118 posts

Welcome to another installment in the Design Challenge Weekly Summary series here at Element14! It’s the tenth and final week of the IoT On Wheels Challenge, and the number of updates that were posted in the last seven days has to be something of a record. More on that in a moment, but first, if you are new to this design challenge take a moment and read my intro post about this challenge.  Additionally, there will be a listing at the bottom of this post with links to my previous coverage of this challenge. OK, enough of the formalities, let's jump right into this challenge, and see what’s happened over its final days!

 

 

IoT On Wheels Design Challenge

 

 

About The Challenge

 

 

Featured as the third design challenge of 2017, the IoT On Wheels Design Challenge opened for project idea submissions in June of 2017, which was met with many submissions from community members. As I mentioned earlier, the challenge is based around the NUCLEO-L476RG development boardNUCLEO-L476RG development board which is built on the STM32L4STM32L4 Arm Cortex M4 line of processors. Challengers have ten weeks to develop their project, and share their progress in a series of weekly update post. By posting a minimum of ten update post, challengers become eligible to win several awesome prizes, and the chance to become one of our prestigious design challenge winners.

 

 

Entering the challenge is not limited to just the ten chosen community members though,  anyone can join the Challenge as a non-sponsored Challenger. Here's how: Simply get the low-cost NUCLEO-L476RGNUCLEO-L476RG and integrate it into your project, as well as post 10 blogs about your design journey in the IoT on Wheels space (tagging your blogs 'IoT on Wheels'). All Challengers must build their projects in accordance with the Challenge's terms and conditions and all projects must include the  NUCLEO-L476RGNUCLEO-L476RG

 

 

The Official Kit, and The Prizes

 

 

On September 4th, 2017 Element14 announced which 10 community members were picked to participate in this challenge, and those 10 challengers received a kit of sponsored components to use in their design which was sponsored by STMicroelectronics. Each kit contains the following items:

 

 

To learn more about each of these components or to purchase them to use in your own project, visit the official kit announcement at the links above.

 

Each challenger is competing to win one of three prize packs that feature prizes ranging from a Segway Mini Pro, to an Oculus Rift VR headset, Bicycle GPS system, GoPro Hero 5, and even a radio controlled hobby truck. Other prizes include tools from Duratool, a bench power supply, and even a high end pair of headphones. All challengers who complete ten blog post and finish their project will also receive a prize pack including a tool kit from Duratool, a heat gun, and digital multi-meter. These prizes are open to all who enter the challenge, despite not being an official challenger, with the requirements being the same: Use a STMicro NUCLEO-L47RG and post ten blog post by the challenge’s deadline on November 13th.

 

 

The Past Week In Review

 

 

Over the past 7 days, November 12th - November 18th, we have had a total of thirty three (yes I said thirty three) updates posted across seven projects. I have not had the chance to cross check my records, but I do believe that is the highest number of updates posted in one week in Design Challenge history! So with that mind blowing information fresh in your mind, let's take a look at which projects were updated this week!

 

 

 

This Week’s Top Updates

 

 

Project: Smart Bike, Smart Rider  BLOG 5 : From BreadBoard prototype To Homemade PCB

 

 

Our first featured update this week is from project Smart Bike, Smart Rider, the brainchild of Gurinder Singh (gsgill112). In the project’s fifth update, we got a short tutorial on etching your own PCB at home. Most of you who have read some of my non-design challenge work here at Element14 will know how much I love PCB design, and seeing challengers like Gurinder etch their own PCBs at home really brings back a lot of memories for me when I etched my first PCBs in my kitchen many years ago. Instead of sharing a quote from the post, I am simply going to ask you to hit the link above, and read this entire post, if not for the knowledge, then for the nostalgia you might experience while reminiscing about your first PCBs.

 

 

Project: Traffic Predictor #13 - Mission accomplished

 

 

You know, if there is anything I love more than source code, design files, and custom PCBs in these projects, it's to see a “mission accomplished” title at the end of the project. That is just what we got in update number thirteen of Dixon Selvan’s (dixon415) project, Traffic Predictor. “This will be last week in the design phase of the IoT on Wheels Design Challenge and for my traffic predictor project. This blog will be a walkthrough of the entire project. The blogs posted over the two months time is at the end of this blog in a categorized format. Check it out if you have missed out any or to better understand the project,” he wrote. I am once again going to ask you to take a moment and read through this entire post. Dixon has done a great job of summarizing the project from beginning to end.

 

 

 

Project: Fatigue Alert System (Blog #10)

 

 

In his tenth and final update to project Fatigue Alert System, design challenge veteran Dale Winhold (dwinhold) finishes off his project with a demo video. “This is the final blog on my project for this challenge. The videos I am attaching is of the finished project. The first video is of the finished project description, showing the different parts put together. The second video is of it working in the vehicle,” he wrote. “I am very happy how it turned out and that it works so well. I feel it will make a difference the way we drive and more aware of how tired we are while driving. This will also work well to stop distracted driving by alerting you when you aren't paying attention.”

 

 

That is going to wrap up things for this week, tune in next week for another Design Challenge Project Summary, and my final post on this challenge once the winners have been announced. I would like to thank all of the challengers for making this such a great design challenge! Awesome work, and good luck to everyone who made it to the finish line! If you would like to learn more about this challenge, and to see all progress has already been made, head over to the its official challenge page, and as always, remember to hack the world and make awesome!

The Past Week In Review

 

 

Over the past 7 days, November 5th - November 11th, we have had a total of thirteen updates posted across seven projects. Before we get to my highlights for this week, let's take a look at which projects were updated this week!

 

 

 

This Week’s Top Updates

 

 

Project: Traffic Predictor #11 - Module 2 and 3 [Completed]

 

 

Our first featured update this week is from Dixon Selvan’s (dixon415 project, Traffic Predictor. In the project’s eleventh update, we learn that modules two and three have been completed, and Dixon lays out the circuit diagram of the entire project. “This blog will be a walk through of the completed modules 2 & 3… The output/ outcome of these modules is the location of the obstacle(traffic) in front of the driver. This will be fed to the mobile app which will handle the rest of the processing.” he wrote. Head over to the link above to check out the full source code for this project, as well as more information on how it all ties together.

 

 

Project: CycleOps Blog #5 - Updates

 

 

Parker Ellwanger (rpbruiser) posted his fifth update to project CycleOps, and gave us the rundown on the mobile app he has been designing which will display all of the data that his sensors collect. “I have added in Bluetooth functionality in order to search for and connect to devices (specifically the IoT bike). I have also added more information on the lock/unlock button as the small icon was hard to see. Below all of this on the homepage I have added weather details so you know whether or not you need to bring your seat cover, or what to wear, or if you should even ride your bike that day…” he wrote.

 

 

Project: The Konker Connection - Blog 10 - Dual LCD Demo

 

 

Our final featured project for this week comes from The Konker Connection, Douglas Wong’s (dougw) project for this challenge. In update number ten, Douglas showcases the custom PCB that he designed to add two Nokia-style LCD screens to. "It is very late in the project to be just starting to build interfaces, with lots of software development still required, but you have to play the cards you are dealt, or in this case, build the cards when you get them," he wrote. Douglas never ceases to amaze me with the amount of custom PCBs he designs for his design challenge projects, which is one of the things that makes his projects stand out so much! Head over to the link above for a demonstration of both LCDs in action.

 

 

That is going to wrap up things for this week, tune in next week for another Design Challenge Summary.

The Past Week In Review

 

Over the past 7 days, October 29 - November 4th, we have had a total of nine updates posted across six projects. Before we get to my highlights for this week, let's take a look at which projects were updated this week!

 

 

 

This Week’s Top Updates

 

 

Project: Smart Drive - Connecting GPS - Blog #5

 

 

Our first featured update this week is from Sergei Vlasov (vlasov01). In his projects fifth update, Sergei shows us how he integrated GPS into the Smart Drive system. “I've purchased a GPS module VK2828U7G5LF. It is based on UBX-M8030-KT chip, antenna and UART interface,” he said... “It was my first experience working with GPS module. I'm generally happy with results so far.The next steps is to explore STM32L47RG serial interface and connect it to GPS module." Check out the full post a the link above to read more, and to view the source code Sergei provided.

 

 

Project Walking Wheels on Water  #12 Motor Driver L298N for N30 DC motor

 

 

In his project’s twelfth update, F. Yao (fyaocn) showcases how he plans to drive the hobby motors that will be used to propel the project in the water. Using a L298N H-Bridge motor driver to power a N30 motor with a 75mm propeller attached. The motor driver will use a 5V source that will be provided by four AAA batteries. Head over to the link above for more info.

 

 

Project: Traffic Predictor #10 - Evading traffic like a Bat

 

 

Our final featured project for this week is, project Traffic Predictor by Dixon Selvan (dixon415).  In his project’s tenth update, Dixon shows off one of the coolest user interfaces I have seen in one of our design challenges. Using an ultrasonic sensor that is mounted to a servo, he has created a sort of 180-degree radar that will allow more autonomy in the autopilot he is designing. Head over to the link above for the full rundown, and a demo.

 

 

That is going to wrap up things for this week, tune in next week for another Design Challenge Summary. I apologize if this weeks update was a little short, as well as a little late.

The Past Week In Review

 

Over the past 7 days, October 22 - October 28, we have had a total of fourteen updates posted across seven projects. Before we get to my highlights for this week, let's take a look at which projects were updated this week!

 

This Week’s Top Updates

 

 

Project: The Konker Connection - Blog 5 - First Program

 

 

Our first project in the spotlight this week comes from design challenge veteran, Douglas Wong (dougw). In project The Konker Connection’s fifth update, Doug demonstrates a simple hello world blinking led after installing the STM Nucleo L476RGSTM Nucleo L476RG  to the Arduino IDE and programming it using Arduino’s beginner friendly programming language. While some may scoff at all things Arduino, you have to admit, that if it gets people using more powerful boards like the STM Nucleo, then that has to be a good thing right? Head over the the link above to watch the demo video.

 

 

Project: Traffic Predictor #6 - Into the traffic [Part 1 of 2]

 

 

In his project's sixth update, Dixon Selvan (dixon415) begins describing how he is tying everything together, and moving the project “into the traffic” so to speak. In this first installment of a two part series he shows off the Android App that he built allow him to send GPS data back to the STM Nucleo board. As it usually goes when developing apps for Android (my experience) there are always several hurdles to overcome. One such hurdle was a lack of ram on Dixon’s computer, which was causing twenty minute delays every time he made a change and wanted to visualize the data generated. Check out part one of this update at the link above.

 

 

Project: Fatigue Alert System (Blog #5)

 

 

Project Fatigue Alert System by Dale Winhold (dwinhold) is once again rounding out our highlight reel for this week. In the project’s fifth update Dale detailed the list of sensors that he will be using in the project. While this is a pretty mundane post, I feel that many challengers overlook important information like this. Seasoned EE’s and makers will be able to easily figure out what sensors, and other hardware that is used in these projects, but complete noobs will struggle with identifying each sensor, much less understanding what it is and why it’s being used. Post like this help those at home who may be following along, and you can check it out at the link above.

 

 

That is going to wrap up things for this week, tune in next week for another Design Challenge Summary.

The Past Week In Review

 

Over the past 7 days, October 15 - October 21, we have had a total of six updates posted across five projects. Before we get to my highlights for this week, let's take a look at which projects were updated this week!

 

 

 

This Week’s Top Updates

 

 

Project: The Konker Connection - Blog 4

 

 

In his fourth update, Douglas Wong (dougw) began tackling some serious issues that have arose in project The Konker Connection. The first issue Doug tackled was with the gas tank level sensor, followed by him designing a custom interface PCB that would implement all of the features of his design. If you have followed these weekly update post, you know that I am a sucker for custom PCBs in projects, and Doug never seems to disappoint. Head over to the link above to see how he is tackling the gas tank issue, and a more indepth description of the custom PCB.

 

 

Project: CycleOps Blog #4 - Finally We Get To IoT

 

 

After doing some research, and obtaining a free $100 voucher at a tech conference, Parker Ellwanger (rpbruiser) made the decision to use Microsoft’s Azure platform as the foundation of his project. After creating an IoT Hub, Event Hub, and Device Provisioning Service, Parker was able to get the connection string and API keys he needed to begin connecting his project to the web. The post is a little lacking in information about the process, but it does help to open up others to the idea of using Azure for their projects as well. Wrapping things up, Parket also shared a link to his Github repository at which you can find the files he is modifying for this project. Head over to the link above to grab that link.

 

 

Project Walking Wheels on Water#10 Create Mobile APP for  X-NUCLEO-IDB05A1X-NUCLEO-IDB05A1 blewrite control LED on/off

 

 

Our final highlight this week comes from project Walking Wheels on Water by F. Yao (fyaocn). In the project’s tenth update F. Yao detailed how he created a mobile app that would eventually be able to control Flywheels, the small airplane he has built as part of the project. As always, he has created a wonderfully detailed post, with the full source code being available for inspection and download at the link above. I would like to urge all of the challengers to include the source code they write in their blog post just like this as it helps those of us following along at home better understand what is happening.

 

 

That is going to wrap up things for this week, tune in next week for another Design Challenge Summary. If you would like to learn more about this challenge, and to see what progress has already been made, head over to the its official challenge page, and as always, remember to hack the world and make awesome!

IoT On Wheels Design Challenge

 

 

About The Challenge

 

 

Featured as the third design challenge of 2017, the IoT On Wheels Design Challenge opened for project idea submissions in June of 2017, which was met with many submissions from community members. As I mentioned earlier, the challenge is based around the NUCLEO-L476RG development boardNUCLEO-L476RG development board which is built on the STM32L4STM32L4 Arm Cortex M4 line of processors. Challengers have ten weeks to develop their project, and share their progress in a series of weekly update post. By posting a minimum of ten update post, challengers become eligible to win several awesome prizes, and the chance to become one of our prestigious design challenge winners.

 

 

Entering the challenge is not limited to just the ten chosen community members though,  anyone can join the Challenge as a non-sponsored Challenger. Here's how: Simply get the low-cost NUCLEO-L476RGNUCLEO-L476RG and integrate it into your project, as well as post 10 blogs about your design journey in the IoT on Wheels space (tagging your blogs 'IoT on Wheels'). All Challengers must build their projects in accordance with the Challenge's terms and conditions and all projects must include the  NUCLEO-L476RGNUCLEO-L476RG

 

 

The Official Kit, and The Prizes

 

 

On September 4th, 2017 Element14 announced which 10 community members were picked to participate in this challenge, and those 10 challengers received a kit of sponsored components to use in their design which was sponsored by STMicroelectronics. Each kit contains the following items:

 

 

To learn more about each of these components or to purchase them to use in your own project, visit the official kit announcement at the links above.

 

Each challenger is competing to win one of three prize packs that feature prizes ranging from a Segway Mini Pro, to an Oculus Rift VR headset, Bicycle GPS system, GoPro Hero 5, and even a radio controlled hobby truck. Other prizes include tools from Duratool, a bench power supply, and even a high end pair of headphones. All challengers who complete ten blog post and finish their project will also receive a prize pack including a tool kit from Duratool, a heat gun, and digital multi-meter. These prizes are open to all who enter the challenge, despite not being an official challenger, with the requirements being the same: Use a STMicro NUCLEO-L47RG and post ten blog post by the challenge’s deadline on November 13th.

 

 

The Past Week In Review

 

Over the past 7 days, October 8 - October 14, we have had a total of nine updates posted across seven projects. Before we get to my highlights for this week, let's take a look at which projects were updated this week!

 

 

 

This Week’s Top Updates

 

 

Project: Smart Drive - Exploring MEMS board X-NUCLEO-IKS01A2 with Unicleo-GUI - Blog #3

 

 

This week was full of great blog post, and the one that really stood out for me was the third update to project Smart Drive. In this post, Sergei Vlasov (vlasov01) walked us through the methods he used to begin logging data such as fall detection, environmental metrics and more using the X-NUCLEO-IKS01A2X-NUCLEO-IKS01A2 expansion board. The X-CUBE-MEMS1 software package was used for standalone data logging as it includes a fall detection library negating the need to write something custom. This update is full of useful information, and I would highly suggest checking it out at the link above.

 

 

Project: Smart Bike, Smart Rider - NexTion Enhanced Heven SbSr

 

 

In its second update, project Smart Bike , Smart Rider saw a fairly interesting display added into its hardware list. The Nextion display is designed to make GUI design easier for those who wish to add a display to their embedded project. Until this project, I had not heard of these displays, but from what I can tell, they are actually pretty useful for projects where a small touch-screen display is needed. The display’s real advantage comes into play with the Nextion Editor, a drag and drop GUI builder, that is capable of creating some pretty robust layouts. Learn more about this display, and how Gurinder Singh (gsgill112)is using it in his project at the link above.

 

 

Project: Fatigue Alert System (Blog #3)

 

 

Our final highlight this week comes from project Fatigue Alert System by Dale Winhold (dwinhold). In the project’s third update Dale clued us onto some issues he was having with the Nucleo-64 boardNucleo-64 board. He’s having issues with his computer recognizing the board when plugged in, and is hoping some community members can lend some troubleshooting advice. He also showcased his plan to use capacitive sensing to determine if the driver of the vehicle’s hands are touching the steering wheel, and sounding an alert if the system detects that the driver's hands have left the steering wheel.  If you think you can be of assistance in troubleshooting the issues Dale has been experiencing, head over to the link above and drop him a comment.

The Past Week In Review

 

Over the past 7 days, October 1 - October 7, we have had a total of three updates posted across three projects. I am going to highlight all three project updates this week. Before we get to that, let's take a look at which projects received their first updates!

 

 

 

This Week’s Top Updates

 

Project: Traffic Predictor #5 - Machine Learning and Building a case for the kit

 

 

In his project’s fifth update, Dixon Selvan (dixon415) educates us on the basics of machine learning and talks about how he will integrate it into his traffic predictor He also covered how he built a case for the Nucleo-L476RG using something other than a 3D Printer “The case has been built to hold/mount the Nucleo-L476RG kit onto the vehicle therefore while on travel we can record the GPS location data in future modules to identify real-time traffic he said. “The case includes two provisions one to hold the MCU board with expansion boards and the other to hold the battery pack power bank Though the case is not an enclosure type it is hard enough to protect the case hold the kit and battery in position even in tough terrains and allows easier access I have added below photos video of the kit inside the case and mounted onto my bike”

 

 

Project: The Konker Connection - Blog 3

 

 

Doug Wong (dougw) is back with another excellent project update. In blog post number three, we get an inside look into his experiments in measuring fuel tank acoustic resonance in an effort to determine fuel levels. He also spent a few minutes talking about his plans for reading GPS data with the Nucleo board. “My system will need GPS data to determine location and time. I don't know yet if there is already a Nucleo library to parse GPS (NMEA) data, but I have been looking into the NMEA sentence structure from my particular GPS module (UBLOX NEO 6M) in preparation for tackling the parsing task,” he said.

 

 

Project: VeTAS - Blog #2: STM32 Setup, Connection & Transmit Data to Cloud

 

 

Our final highlight this week comes from project VeTAS by Shantimohan Elchuri (shantimohan).  In the project’s second update focused on the STM32 Kit with a quick tutorial on how to set it up and connect it to the cloud. “I am planning to use cloud to store data and manage alerts. Currently I plan to use Azure IoT Hub for this purpose as I have already worked with it as part of me attending various Microsoft IoT workshops and training sessions. I also got Azure subscription as part of my MSDN subscription. That is the reason why I selected Azure as my cloud component,” Elchuri said.

The Past Week In Review

 

Over the past 7 days, September 24 - September 30, we have had a total of thirteen updates posted across eight projects. With so many updates this week, I am going to highlight three project updates that I felt stood out. Before we get to that, let's take a look at which projects received their first updates!

 

 

 

This Week’s Top Updates

 

Project: Smart Drive - First Steps with mbed os - Blog #2

 

 

Making his design challenge summary debut, Sergey Vlasov’s (vlasov01) second update to project, Smart Drive, is our first featured blog post this week. With a secure internet connection being major requirement for his project, Serjey decided to utilize our old friend MQTT as the messenger that would relay data from his sensors to his main node. “My project requires a secure connection with Internet to exchange information. I've selected MQTT protocol as it is open, lightweight (low power consumption), supports data confidentiality (TLS) and widely adopted (including client for STM32,” he said. The frequency in which we see projects that use MQTT in design challenges is a true testament to how powerful and easy to use this almost two decade old protocol is. Head over to the link above to check out the full blog post.

 

 

Project Walking-Wheel on Water#4 Coding on Nucleo-STM32L476 with MEMS board  X-NUCLEO-IKS01A2X-NUCLEO-IKS01A2

 

 

F. Yao’s (fyaocn) project, Walking-Wheel on Water saw the most activity this week with a total of five updates. We are going to focus on update number four in which he walks us through his process to interface the X-NUCLEO-IKS01A2X-NUCLEO-IKS01A2 extension board with the nucleo-STM32L476 development boardnucleo-STM32L476 development board. “The  X-NUCLEO-IKS01A2X-NUCLEO-IKS01A2 is a motion MEMS and environmental sensor expansion board for the STM32 Nucleo It is equipped with Arduino UNO R3Arduino UNO R3 connector layout and is designed around the LSM6DSL 3D accelerometerLSM6DSL 3D accelerometer and 3D gyroscope the LSM303AGR 3D accelerometer and 3D magnetometer the  HTS221HTS221 humidity and temperature sensor and the LPS22HB pressure sensor The  X-NUCLEO-IKS01A2X-NUCLEO-IKS01A2 interfaces with the STM32 microcontroller via the I²C pin I the sheme there are two I2C ports I2C1 and I2C2 While the I2C1 and I2C2 share same I/O pins so the I2C1 and I2C2 are same he said.

Welcome to another installment in the Design Challenge Weekly Summary series here at Element14! It’s week two of the IoT On Wheels Challenge, and things are getting off to a great start. Before we jump into the challenge, you should take a moment and read my intro post that will fill you in on the full details of the challenge as well as the challengers who are competing to win some amazing prizes. Additionally, there will be a listing at the bottom of this post with links to my previous coverage of this challenge.

 

If you are new to the Design Challenge series here at Element14, or my weekly summary series in general, I would like to take a moment to explain what these post are all about. Each week, usually on Monday, I release a new design challenge weekly summary post. I create these post to help those following the challenges better understand what happened within the challenge over the past week. I post a list of each project that got updated, and then highlight between two and three project updates from that week that I felt deserved recognition. This will be my 9th Design Challenge, and as you will see, I truly enjoy watching the challengers and their projects grow over the course of the challenge.

 

I sometimes get asked about my involvement in the judging process, and other than sometimes writing the winners announcements, I have no involvement in the selection, debating, or judging, processes. Early on, I was asked to advise on the Sudden Impact Design Challenge, but I was not writing weekly content for the challenges back then. Furthermore, my opinions have no bearings on the outcome of any of the judging process. Additionally, I wanted to touch on one more topic. I get asked a lot about how projects get featured in this series, and my answer is quite simple. Create a well written, information rich, and visually pleasing project update. Include source code, schematics, design files, and tutorials in your updates. It’s that simple. So, enough with the formalities, let's get on to why you are really here!

The Past Week In Review

 

Over the past 7 days, September 17 - September 23, we have had a total of seven updates posted across six projects. With so many updates this week, I am going to highlight three project updates that I felt stood out. Before we get to that, let's take a look at which projects received their first updates!

 

 

 

This Week’s Top Updates

 

 

Project: Smart Road - Pack Arrives and the fun begins

 

 

In his project’s second post, Grant Colgan (brains93) sits down to and talks about his ideas for this project, and unboxes the official challenger kit.  “My plan is to make the roads safer for all users by giving them more information about the road ahead of them so that they can adjust accordingly…” he said. If you would like the full rundown, head over to the link above for a fifteen-minute video where Grant breaks the project and kit down.

 

 

Project: The Konker Connection - Blog 1

 

 

I was quite excited when I saw that Douglas Wong (dougw) was chosen as a participant in this challenge as his projects never seem to disappoint. I became even more excited when I realized that his project centered around providing current road condition data to his motorcycle using sensor nodes placed along the roadway, with a receiver on the motorcycle. In his project’s first update post, Doug fills us in on his plans to accomplish this, as well as breaking down the modules he will be using to build the sensor nodes and receiver. Check out the full post, and video at the link above.

 

 

Project: CycleOps Blog #2 - Locking Mechanism and More Design Overview

 

 

Parker Ellwanger (rpbruiser) is back for his second weekly highlight of project CycleOps, and this week he became the first challenger to post actual physical progress on his project. With one of the main parts of his project being a smart lock that secures the bicycle’s wheels to its frame, this was the first concept he began working on by designing and 3D printing a prototype of the locking mechanism. If you have read my past summaries, you know that including a 3D printer in your project’s build is the fastest way to catch my attention, and this weeks update did just that. Head over to the link above to find out how Parker designed this neat looking lock concept.

Include source code, schematics, design files, and tutorials in your updates. It’s that simple. So, enough with the formalities, let's get on to why you are really here!

 

 

IoT On Wheels Design Challenge

The Past Week In Review

 

Over the past 10 days, September 6 - September 16, we have had a total of four updates posted across three projects. Since this is the first “week” of the challenge, I am going to kick off my coverage of it by highlighting all three projects. Before we get to that, let's take a look at which projects received their first updates!

 

 

 

This Week’s Top Updates

 

 

Project: Walking-Wheel on Water  #2 - Hardware Parts Nucleo-L476 and IDB04A1-BlueNRG

 

 

In his project’s second update, F. Yao (fyaocn) introduced us to some of the hardware he would be using to build his water takeoff and landing capable glider plane. He plans on using ARM MBed to program the STM32-L476 but mentions that it would be a better option if it was a fully open source solution. He went on to talk about implementing Bluetooth into the project as well. Head over to the link above for the full rundown.

 

 

Project: Fatigue Alert System - Blog #1

 

 

Dale Winhold (dwinhold) kicked off project Fatigue Alert System by giving us a little context on what inspired him to join this challenge. He suffers from a severe sleep disorder that could cause him to fall asleep at the wheel while driving, this situation is exasperated by compounding fatigue factors. Fatigued driving is a major issue worldwide, and Dale wants to create an alert system that will notify drivers that it is not safe for them to drive. His first project blog details how he will monitor driver fatigue, and what his plans are for alerting the driver. Head over to the link above to read his full plan.

 

 

Project: CycleOps Blog #1 - Design Overview

 

 

 

 

 

Inspired to build a device that makes bicycle security safer, smarter, and more technologically advanced, Parker Ellwanger (rpbruiser) introduced us to project CycleOps this week. The concept behind this project is that most bicycle security systems are of the dumb variety, and with the current state of microelectronics and the Internet of Things, there is no reason not to have a fully featured electronic security system for bicycles. He has some pretty good ideas, and will be using a pretty cool framework to power the app that will tie this project together. To find out what that framework is, head over to the link above.

 

 

That is going to wrap up things for this week, tune in next week for another Design Challenge Summary. If you would like to learn more about this challenge, and to see what progress has already been made, head over to the its official challenge page, and as always, remember to hack the world and make awesome!

After a brief hiatus another design challenge is upon us here at Element14, and that means that my weekly summaries are returning as well. Before we get started with week one, I want to take a moment and fill you in on the details of this new challenge. Dubbed IoT On Wheels, this design challenge is centered around the NUCLEO-L476RGNUCLEO-L476RG development board from STMicroelectronics, and task its challengers to utilize the Internet of Things to make their car, bicycle, or other wheeled transportation smarter, safer, and easier to use. If the previous two design challenges from 2017 are any indication, we are in for a real treat over the next few months, so let’s dive a little deeper in and learn more about this challenge, and its challengers.

The Challengers and Their Projects

 

I have listed out each project with a link to its respective challenger’s profile page. Below each project is a brief description of the project in its creator's own words. I will update this info once project names have been set in stone, and their blog pages created.

 

Project: Smart Bike Smart Rider (SbSr) by Gurinder Singh Gill (gsgill112)

Gurinder endeavors to build a smart bike that will detect pot holes advise on weather conditions and grade a cyclists ride based on gradients of hills Safety is another key feature that will get an overhaul with the  X-NUCLEO-IKS01A2X-NUCLEO-IKS01A2 Board

 

Project: Smart drive by Sergey Vlasov (vlasov01)

“I'd like to build a collaborative system, that will connect different participants on the wheels. They will be able to share data collected during their travels, Especially valuable will be data related to events like emergency breaking, collisions, crashes, this data will be linked to the position, speed and other information collected from the sensors."

 

Project: The Konker Connection by Douglas Wong (dougw)

"My Konker motorcycle is a great little machine for exploring the backwoods, overgrown trails, seldom used pathways, dirt trails and back roads. It is street legal but it is designed and built to go off-road. I also use it for commuting to work as it gets great gas mileage. It has only rudimentary instrumentation - in keeping with its rugged purpose, but I would like to outfit it with some useful extra features and this design challenge is a perfect excuse to take a run at implementing them."

 

Project: Avoid the Bump by Abhijit Nathwani (abhijitnathwani)

"The idea is to create a system which tracks the potholes as the vehicles navigate through the city and locate their geographic location so that it is easy for the authorities to fix them. Through the system, I plan to remove one major hurdle/excuse for the authorities claiming they do not know the location of the damaged roads and potholes."

 

Project: Vehicle Temperature Alert System (VeTAS) by Shantimohan Elchuri (shantimohan)

"Now a days we have been hearing about death of children being left inside hot cars. None of the vehicles driven today, old or new, have any way of intimating the drivers that either the car interior is getting hot, left a kid in the car or both. Hence this VeTAS project will enable the drivers to get notification when things are going wrong. "

 

Project: Traffic Predictor and Auto Pilot by Dixon Selvan (dixon415)

"It is everyone who will be annoyed to end up on a busy street with never ending traffic. This made me come up with an idea to machine learn and collect information through the mass storage capability of STM32 Nucleo-64 development board. Using the information collected, we can predict the routes the user use and the traffic he/she will face. We can suggest him/her with the alternative route or time which will save him/her from the traffic."

 

Project: Smart Road by Grant Colgan (brains93)

"I had though, why make a vehicle smarter when you could in theory make all vehicles smarter by making the roads smarter. Using a fabric (or some other means of integrating with the tarmac) you could have smart patches throughout a road with various sensors for measuring temperature, humidity, wind speed and average speed of traffic, the smart road could then broadcast status messages to a console in a car warning of Ice, high winds or even if the traffic is slowing rapidly. This could be made available via a custom made device to pick up the signals or using an app for the consoles which are in built in most cars."

 

Project: Fatigue Alert System by Dale Winhold (dwinhold)

"I have a sleep disorder and this ups the possibility of falling asleep while driving. Fatigue is a factor in up to 21 per cent of motor vehicle collisions, resulting in about 400 deaths and 2,100 serious injuries every year. At 21 per cent, fatigue would rank as the third highest cause of collisions behind impaired driving and speed. This is an issue that needs to be addressed."

 

Project: Walking Wheels on Water by F. Yao (fyaocn)

"Make the wheel walking on the water is to make one plane on floating barrel and passive wheels. The plane can not fly on air, but can float on water and move on road. Driven by propellers."

 

Project: Cycle-Ops Security by Parker Ellwanger (rpbruiser)

"Most people who ride a bicycle on  a regular basis are aware that it is of up most importance to secure your bike, as it is a significant investment, and you would not want it to be gone by the time you get done at work or in the grocery store. Many people are also aware that it isn't as easy to have GPS or use one's phone for navigation on bike as it is in a car or motorcycle. This project interest me as I have seen many bicycles on my college campus stolen and is one of the reasons I have hesitated in bringing one myself. If I can increase security and safety through making a smart bicycle I feel as though it would make it easier for more people to use the bicycle as a mode of transportation."

 

As I mentioned earlier, you do not have to be one of the ten chosen challengers to participate in this challenge and still be able to win a prize. Element14 encourage’ anyone who wishes to participate in this challenge to do so. Simply include a STMicroelectronics NUCLEO-L476RGNUCLEO-L476RG in your project, and then post ten project update blogs across ten weeks.

 

That is going to wrap up things for today, I am a little behind due to power outages and other issues from Hurricane Irma, but I plan on getting out week 1’s update later today. Then you can check back each and every week for the duration of this challenge for a summary post from the previous week’s updates. If you would like to learn more about this challenge, and to see what progress has already been made, head over to the its official challenge page, and as always, remember to hack the world and make awesome!

Welcome to installment number thirty-one of the Design Challenge Project Summary series here at Element14. For those of you who are new to my content, in this series I chose  a single Design Challenge project from current or past challenges, and write a short summary of the project to date. I am selective about which projects I summarize, as I want to highlight quality content. Unfortunately, projects that stall out, or get abandoned, are not chosen for summaries. Some project creators like to keep their own project summary going, and this series is not meant to overshadow those post, but to highlight each project from an outsider's perspective.

 

CCI27012017.jpg

 

The subject of this installment is project Safety Jacket for the Tolling Industry which was part of the Safe & Sound Design Challenge, by Inderpreet Singh (ipv1). The project began the 20th of February 2017 with Inderpreet giving us a little context, and explanation of why he wants to, and how he plans to improve the safety of tolling station workers. As a former R&D engineer at a tolling company, he was Inspired by a traumatic accident that occurred within the company when a toll booth worker was struck and killed by a car. Inderpreet feels that this incident could have been avoided with better communication between the workers, and to solve the issue, he will build a sensor-rich safety jacket that is connected to the IoT, making communication between workers much faster.

 

 

While waiting on the hardware kit to arrive, Inderpreet took some time to re-familiarize himself with the Launchpad ecosystem, and wrote a quick tutorial on how to interface the MSP430G2553MSP430G2553 with the CC110L BoosterpackCC110L Boosterpack. A week later with the package from Element14 still in transit, he used his third project update to discuss the use of TI RTOS with Code Composer Studio 7 as well as on pThreads for the readers who are familiar with POSIX. The challenger kit finally arrived a few days later, and Inderpreet used his fourth project update to share the unboxing festivities with everyone.

In update five and six, Inderpreet took his time to teach us the basics about writing our own protocol stacks for the MSP432MSP432 and TI RTOS. Tutorials like these are one of the major reasons I love the Design Challenge Series here at Element14. They provide a wealth of knowledge, and help simplify often heavy subjects into something non-engineers can understand too. If you are interested in learning how to write you own protocols, this is definitely a pair of post to check out.

 

 

Update seven marked out first look at Cloud CCS since the project started, and instead of writing a few thousand words, Inderpreet decided to explain Code Composer Studio and the TI Resource Explorer by making a video which can be seen above. He then ended the post by mentioning a few issues he is having which are slowing down progress including: issues with MQTT, an unwritten BLE app, and power issued that need to be resolved by integrating a super capacitor.

 

 

Updates eight and nine were both short, and spanned about three days between the two. In update eight, we got to see some of Inderpreet’s experiments on energy harvesting using the BQ25504 and BQ25570 modules. Update nine focused on a 3D printable enclosure for the CC1310 Launchpad. If you are interested in printing this case for yourself, check out the post for a download link.

 

IMG_1864.jpg

 

With the final week of the challenge now here, Inderpreet used the project’s tenth update to write a long and informative post summarizing what he had completed on the project so far. The first topic he touched on was how the project had evolved overtime, and quickly moved into explaining the project’s first working module. This module featured most of the sensors, and the communications core that would relay data back to a central unit. Ending the post with a update on what is left to be done, as well as some photos of the 3D Printed enclosures, Inderpreet was happy with the progress he had made so far.

 

IMG_1895.jpg

 

Update eleven arrived three days later on July 9, 2017, and more work was done on the energy harvesting portion of the project. After some testing, Inderpreet determined that a small solar panel could be used to charge a super-capacitor which would in turn power the small Sharp LCD screen he mentioned in a previous post. More work on this topic continued into update twelve, with wireless charging being the main focus. Using the TI Fuel Tank booster PackTI Fuel Tank booster Pack, and the Qi Wireless Charging KitQi Wireless Charging Kit, two significant parts of the project were completed and checked off of the list of things to do.

 

 

Inderpreet wrapped things up in the project’s thirteenth update, with a full demonstration of the safety jacket in its current state. Again he felt that while the project needed a written demo, a video would be much better medium to explain how it works. With that said, I am going to let you watch the video above, and when you are finished, head over to the project’s fourteenth and final update for a full rundown of the project in Inderpreet’s own words.

 

That is going to wrap up my project summary coverage of project Safety Jacket for the Tolling Industry.This project ultimately went on to receive an honorable mention from the challenge’s judges, and I felt that this was well deserved. While the project got off to a slow start, Inderpreet made up for it with several tutorials and pieces of semi-related content to fill the gaps. I learned a good bit about the Launchpad ecosystem from this project, as well as some programming knowledge as well. If you have not yet read through the whole project, I highly suggest doing so by visiting its blog page. Tune in later this week for another Design Challenge Project Summary here at Element14. Until then, Hack The World, and Make Awesome!

WearableSensors.jpg

 

The subject of this installment is project Invisible Hazardous Environmental Factors Monitoring System which was part of the Safe & Sound Design Challenge. Conceived and built by Douglas Wong (dougw), project Invisible Hazardous Environmental Factors Monitoring System was the grand prize winner of this challenge, and quite frankly, it is one of the best projects I have seen in all of the design challenges I have covered over the last four years. Since this project contained more than twenty updates, I will be skipping some of the shorter updates in this summary.

 

ultra-uv-sun-1.jpg

 

In the project’s first post Douglas pointed out several invisible, yet potentially dangerous, man made and naturally occurring environmental hazards that could create heath and safety issues for humans living, working, or recreating near them. The list included things like the side effects of RF radiation, radon gas exposure, exposure to UV light, as well as several other scenarios. To help better understand if any of these conditions could be cause for health and safety concerns Doug decided to build system of wearable sensors that would allow researchers to collect data that will be vital to understanding what risk there might be when in these conditions.

 

SafeSoundBlockDiagram1.jpg

 

In update two, Douglas laid out his plan to build the ultimate wearable, environmental data gathering, system of sensors which would feature several components from Texas Instruments including: the EXP432P401REXP432P401R development board as the main board, 430BOOST-SENSE1430BOOST-SENSE1, LCD Booster PackLCD Booster Pack, Sensor Booster PackSensor Booster Pack, and CC3100MODBOOSTCC3100MODBOOST WiFi Booster Pack, as well as several supporting sensors from other manufacturers. With the hardware list complete, he then went on to explain that his vision is to build several modules that can be mounted to a user's arms and clothing, each featuring an LCD screen, with the overall look being something that is aesthetically pleasing, and comfortable for the end user. Of course the functionality has to be there as well, and this is why Doug also plans on pushing the data to a networked device via the WiFi Booster Pack, which will allow the data to be analyzed later from the comfort of one's office.

 

UVcct1a.jpg

 

With the concept committed and the outline for success written, it was time for Douglas to begin the process of bringing this monitoring system to life. To do this, he began by talking about what UV radiation is, how it is harmful to humans, and how he plans on measuring it. Since UVA and UVB wavelengths fall between 280 and 400 nm, the ML8511 photodiode was chosen to serve as the projects UV radiation sensor. This did however create a small issue that Douglas was quick to solve. The issue was that while the sensor was designed to measure these wavelengths, it was not designed to be sensitive at the levels of UVA and UVB that reach the Earth from the sun. To rectify this problem he decided to use a general purpose offset and gain adjustment circuit to amplify the signal so that it can be read by the analog channels on the MSP_EXP432P401RMSP_EXP432P401R.

 

MQxCCT.jpg

 

Update four was dedicated to Air Quality, and all of the common everyday items that can off gas potentially harmful gasses into the air we breathe. Things like air fresheners, dryer sheets, mattresses, and many other things release gasses that in large enough quantities, could cause health issues in humans and pets. While many of these gasses are easy to identify by their noxious smells, some are odorless, and require detection through other means. Three MQ style gas sensors will be used to detect these so-called “odorless” gasses, with these sensors mating to a custom booster pack that Douglas will design and have manufactured. This was quite a long and informative post, so I highly suggest you read through it to get a better grasps on how each of the three gas sensors will be utilized.

 

MQxBooster.jpg

 

With the arrival of week five, Douglas shifted into high-gear and got to work designing what he dubbed to be the “Hazardous Gasses PCB.” This PCB will house the three gas sensors mentioned in his previous update post, and was designed to fit on top of the MSP-EXP432P401RMSP-EXP432P401R just like a normal “booster pack” with its pins carefully selected to avoid interference with other booster packs used in the project. There were however still pin conflicts with certain booster packs, and as such, Douglas created a table showing which pins each booster pack uses. He also advised that one should cross reference this list when using conflicting boards, and adjusting their jumper pins accordingly. Like the last, this update post was incredibly informative, and is a valuable resource to anyone who is mixing and matching booster packs on the MSP EXP432P401RMSP EXP432P401R.

One odorless and quite deadly gas that was not mentioned earlier is Radon Gas, which is a radioactive noble gas that emits an alpha particle when it decays. Update six tackled this issue. These alpha particles are able to penetrate human flesh, killing the cells they penetrate, and sometimes modifying the DNA contained within them, which is what makes them so harmful to humans. While these alpha particles do not penetrate our exterior flesh very far, they are able to penetrate lung tissue quite well, leading to lung cancer and other illnesses when radon gas is inhaled. Unfortunately measuring Radon levels is a time consuming process that involves analog capture methods like charcoal canisters, and laboratory-grade measuring equipment.  In an attempt to somewhat detect the presence of radon gas, Douglas plans on using a Radiascan 701 radiation detector to detect a presence of alpha particles. This device features a USB port for remotely monitoring the data it collects which should allow for that data to be ported to the monitoring system fairly easy.

 

 

GasSensors1a.jpg

 

In the project’s seventh update, Douglas posted a short video of himself unboxing the challenger kit, so head to the link above if you want to check that out. Moving on to update eight Doug went about configuring the system to work with the Sharp LCD booster packSharp LCD booster pack, which involved desoldering an SMD resistor and moving it to another location on the booster pack’s PCB. With that done, the next hurdle to overcome was getting the LCD and MSP-EXP432P401RMSP-EXP432P401R to play together nicely in Energia, which culminated in Douglas sharing the source code to make this happen, as well as a short demo video of the project so far.

 

2017-09-13 03_10_44-Safe and Sound _ Aut... _ element14 _ Safe and Sound.png

 

Update nine was a short one describing Douglas’ struggles with MQTT, some of which caused a lot of stress. If you are having trouble with MQTT and the MSP-EXP432P401R MSP-EXP432P401R, be sure to check out the link above for some links to additional software that might be required to make everything work as it should. His tenth update was quite short as well, with Douglas showcasing the Hazardous Factors Sensor PCB that had arrived. He includes a short demo video in each of these post, so be sure to check them out.

 

FireAlarm.jpg

 

A week later, we saw Douglas walking around his town and around his home checking the levels of extremely low frequency electromagnetic radiation that exist in everyday life. Everything from the power lines feeding our homes, to the electric razors we shave with emit ELF electromagnetic radiation. Measuring these levels at different locations could prove to be useful in studies on how certain technologies can cause harm to humans. Doug ended this post after displaying readings from around his town and home, and said that he would revisit the topic at a later date.

 

MQTT_IHEF.jpg WearableMQTTsubscriber.jpg

 

 

Fast Forward a couple of weeks and Douglas has gotten more work done on the MQTT side of things, as well as finishing up the design and 3D printing of a housing for the various wearable sensor packages. This brings us up to the week fourteen project update post, which starts off with a demo video showing off the progress on the project so far, and ends with a short section on the radiation meter that Douglas purchased for the project.

 

WiFiClient.jpg

 

Week fifteen arrived with another project update post on microwaves, and their dangers to living organisms. Douglas showed off more test he had conducted. Unfortunately there was still no mention as to how he would integrate this data into the project, but he did summarize his findings and offer tips to help those interested reduce their exposure to microwave radiation.

 

GasSensorModule.jpg

 

Another week passed which meant that another project update was to come. This time, we got a better look at the booster pack hardware stack fully assembled. Although Douglas was feeling a bit under the weather, he managed to finish assembling the gas sensor board, and showcased an older RF sensing board he built previously for another project. While he still had some of these boards, he opted to go with another pre-built solution that featured an OLED screen to display its data. Unfortunately the pre built unit that he ordered was sensitive in the wrong frequency range, forcing him to order another unit of the proper specifications.

 

IHEF_system1.jpg

 

With the end of the challenge almost here, Douglas dedicated the project’s eighteenth update to showcasing what the completed project looked like and was capable of doing. He said that most of the previous week was spent designing and 3D printing more enclosures, and working out all of the mounting options as well as tweaking things to function better. The end result was nothing less than amazing, and what I feel is one of the better design challenge projects we have had here at Element14. The project continued on after this date (and the challenge’s closing) with Douglas running more microwave radiation test, project spin-off’s, and a couple (1, 2) of other update post showcasing more testing that he did after the challenge’s end.

That is going to wrap up my project summary coverage of project Invisible Hazardous Environmental Factors Monitoring System. After watching this project develop from the start, I was sure that it would place high with our judges, and my assumptions were correct. Douglas was named the grand prize winner of the Safe and Sound Wearables Design Challenge. While my coverage, opinions, and writings have no weight with the judges, I felt that this project was the clear winner due to its in depth updates, and how educational nearly all of its blog post were. Douglas tackled many issues head first, and instead of abandoning the project, or removing features, he found solutions to them, even if that solution took days to figure out. Douglas has always had very well written and very technical yet easy to follow project updates, so I expected nothing less from him, and he did just that. Future challengers would be wise to study his past projects, and take note of how they flow, and the level of detail they feature. This post is getting quite long, so I am going to end it here. If you have not yet read through the whole project, I highly suggest doing so by visiting its blog page. Tune in later this week for another Design Challenge Project Summary here at Element14. Until then, Hack The World, and Make Awesome!  

Welcome to installment number twenty eight  of the Design Challenge Project Summary series here at Element14. For those of you who are new to my content, in this series I chose  a single Design Challenge project from current or past challenges, and write a short summary of the project to date. I am selective about which projects I summarize, as I want to highlight quality content. Unfortunately, projects that stall out, or get abandoned, are not chosen for summaries. Some project creators like to keep their own project summary going, and this series is not meant to overshadow those post, but to highlight each project from an outsider's perspective.

The subject of this installment is project Trackable Safety Helmet for Miners which was part of the Safe & Sound Design Challenge. The project’s designer, Mehmet Bozdal (mbozdal), said that his idea for a trackable safety helmet came to be after he learned of the extreme dangers and subsequent catastrophic disasters that claim dozens of lives every year for those on the front lines in the coal mining industry. Citing methane gas explosions as being the main cause of these disasters, his trackable safety helmet could help provide an early warning of high-gas levels, and also provide a trackable beacon in the event of an emergency.

 

In the project’s introductory post Mehmet posits that since methane gas is the main cause of the majority of coal mine explosions, he should focus a significant portion of his project on detecting and warning the miners of the pending danger. To do this, he needs to use a gas sensor that is capable of detecting methane concentrations as low as 5%, the minimum amount of the gas that is needed to promote ignition. With this knowledge he decided to use a Methane CNG Gas Sensor which is capable of detecting methane concentrations from 200 parts per million (ppm) to 10,000 ppm.

 

With a gas sensor chosen, Mehmet moved on to identifying more parameters that might alert the miners of worsening conditions within the mine shaft, and settled on building out the helmet to monitor several more factors including temperature, barometric pressure, and relative humidity as each of these metrics can change the point at which the methane gas could ignite. Other talking points covered in his introductory post include the addition of an RFID and IMU tracking systems, and implementation of a wireless communication link between the miners and a centralized system that would be able to aggregate all of the data collected from the miners helmets which could be analyzed to trigger a warning system, as well as reporting each miner’s position in the mine shaft.

The regulations for electronics in explosive environments was the focus for the project’s second update post, and it really helped bring into focus how dangerous this could really be. Many people believe that a spark is required for ignition, but in a gas-rich environment, something as simple as an overheating voltage regulator could trigger ignition if its temperature rises too high. Since this testing is quite time consuming, and very costly, Mehmet acknowledges that this type of testing is outside the scope of this project, and that he wanted to mention this type of testing anyway because if this project were brought to market, it would have to receive the proper testing.

 

“Simple device is defined 3.12 of the ANSI/ISA-RP 12.6-1987 as any device which will neither generate nor store more than 1.2 volts, 0.1 amps, 25 mW or 20 μJ." Simple devices can be used intrinsically safe and do not need to be approved. Therefore, LEDs, thermocouples may not need an approval. Unfortunately, my design is not in this category because it requires 3.3V or even 5V for sensors This means that this particular design should be tested in accredited testing laboratories. This is way beyond the aim of the contest and my capabilities (at least for now ),” he said.

With the basics of intrinsic safety covered, it was time to move on with the project and start thinking about how the safety helmet will communicate with different systems within the mine and on the surface as well. While wireless communication is the obvious solution here, but Mehmet has to contend with a lot of earth between the miners and the control room on the surface. To combat this, mines generally have two different communication systems (primary and secondary) that help negate this issue. Primary communication systems usually operate in the high frequency and very high frequency ranges while secondary communication systems work in the low frequency range so that its more powerful signal can punch through the earth and make its way to the surface. Visit the project’s 3rd update to learn more about the protocols that drive these systems and to find out which solution Mehmet chose for this project.

In the project’s fourth update, Mehmet gleefully informed us that his challenger kit had arrived after an unexpected trip to Canada. This allowed the project to move from the planning stage, to getting some actual prototyping work done. To get started, he selected the MSP432 and Wi-Fi boosterpack which would allow him to begin the initial configuration in the next update.

Admitting that he had never used a RTOS before, Mehmet moved into update 5 by challenging himself to learn the basics of TI-RTOS instead of taking the easy way out and using Energia, and Arduino-like IDE designed to make programming the MSP432 series easy. To get started he briefly showed readers how to configure a timer within TI-RTOS and how to write and configure a client on the CC3100 module. To finish up the post, Mehmet showed off a small “Ground Operations Center”  program that he wrote to get the project started. He said that while this is just a basic socket program at the moment, he would add more features in the future.

After a two week absence, Mehmet returned with his sixth update post. This update was all about getting some sensors up and running, but as Murphy’s Law states, whatever can go wrong, will go wrong. While working on interfacing the sensor booster pack, Mehmet discovered that the sample code provided with the sensor pack did not work with TI-RTOS, despite the raw sample code working on its own. This was an issue because integrating the raw sensor code with the WiFi code, could cause timing issues which is something he would like to avoid. To remedy this, Mehmet decided to forego the TI sensor booster pack, and move to an Arduino to collect the sensor data he needs.

Update seven was short, but we saw more work completed on the helmet’s sensors, and the methods used to get data from the Arduino and MSP432 boards to the central computer. Mehmet's plans have the project utilizing each boards serial port to transfer data back to the computer, but this meant that he would have to add the UART driver to the WiFi code he wrote previously that connects the MSP432 to his wireless network. He includes this updated code as well as the TCP Echo source code at the end of this post. Finishing things up, mehmet  said that he “has ordered a MSP430 for NFC communication. It will control the gate and send data to the computer via serial port.”

While the idea to use an arduino to capture the data was a good one at the time, Mehmet was not happy with the fact that the arduino’s size created a problem with being able to fit the project neatly into a safety helmet. This forced him to sit down and modify the Sparkfun MSP432 library to add in support for the ADXL345. With this complete, he was able to remove the Arduino completely from the project, and return to the original plan of using the MSP432 as the primary microcontroller for this project. This post was by far the most informative and well written so far, and I would highly suggest reading through it to learn more, and don’t forget to check out the source code Mehmet has included while you are there.

Update nine was not very long but it confirmed a major milestone had been completed Utilizing the helmet for access control was always a part of what this project set out to accomplish and this is what Mehmet focused on for this update Using a passive RFID tag in combination with the  DLP-7970ABPDLP-7970ABP NFC Transceiver Boosterpack was able to write code that will send user IDs that have accessed a locked portion of the mine in an effort to generate accurate and up to date reports of which miner is at which location in the mine “It will read the tag and send the data over the serial port (the msp430 board convert serial to USB) to the Ground Operations Centre. The Ground Operations Centre will decide to doors open,” Mehmet said. “It registers the users who access the mining side so if multiple access occurred from a single tag it will deny the access.”

 

 

Mehmet continued work on the access control portion of the project in update ten, and showcased the system working with some new features in the video above. “The system is consist of NFC reader and NFC tag. In reality, short range RFDI system will be suitable hence NFC allows a few cms which is very short distance. However, the implementation of the system and how it works is completely the same,” he said. Mehmet included sample code, and a more thorough explanation of how this works in the body of the post, and I highly suggest checking it out, as it is quite informative, especially if you are trying to integrate NFC in your own MSP432 project.

One of the best moments in a design challenge project is when everything comes together and the first working prototype is debuted. In update eleven was dedicated to just this milestone, with Mehmet demonstrating the Smart Helemt V0.1. “I will demonstrate the Smart Helmet v0.1  I am always on the move so I struggle to find time but slowly going further. Let's summarise what have done up to now. I am using TI-RTOS. I stack the Wi-Fi booster pack to MSP432. Connect ADXL345 accelerometer and TMP102 using I2C interface. Detect free-fall, inactivity, and send all the data to Ground Operations Center over Wi-Fi using TCP/IP protocol,” he explained. “I coded Ground Operations Center using C and it still needs some modifications  DLP-7970ABPDLP-7970ABP boosterpack is connected to Ground Operations Center via UART interface It controls the gate and doesn't allow unauthorised access and access without the helmet

 

 

Update twelve continued the demonstration, this time giving us a video walk through of what the helmet is capable of. Unfortunately, this is the point in the project in which we find out that the original plan to include a methane sensor was scrapped due to the fact that a portable version of the methane sensor that is required simply does not exist. This is because all of the small methane sensors utilize a heating element for analysis, and that heating element would cause the helmet to fail intrinsic safety testing, and would likely cause an explosion in a gas-rich environment. While this is a bummer, Mehmet did not let this bump in the road stop progress on the project. In the video above you can see the helmet and its electronics working and sending data back to the Ground Operations Center.

 

That is going to wrap up my project summary coverage of project Trackable Safety Helmet for Miners. While this project was not as rich with knowledge as some of the others in the Safe and Sound Wearables Challenge, I chose to include it here because it illustrates what a complete project can be. All too often we see many projects that hit a major bump in the road, which causes progress to stall, if not die out completely. Despite several large hurdles, Mehmet continued to press forward with the project, and in the end, this perseverance led to him receiving an honorable mention from the judges.  If you have not yet read through the whole project, I highly suggest doing so by visiting its blog page. Tune in later this week for another Design Challenge Project Summary here at Element14. Until then, Hack The World, and Make Awesome!  

 

The Upcycle It Design Challenge achieved liftoff in March of 2017 and marked our second challenge of the year, and what a challenge it would become! The challenge tasked its participants to up-cycle an obsolete item, computer, piece of electronic equipment or appliance and make a cool new electronics project built around the Intel® Edison Kit for Arduino. The participants did just that, as this challenge saw record numbers of updates being posted each week, and the resulting projects were nothing short of amazing.

My Top Projects

 

 

There were a few projects that I considered quite exceptional during this challenge. I do not have any set criteria that I use to determine what makes a great project, but I do look at a few key factors when determining which projects I feel are awesome. I also want to note that my opinion on which projects were the best have no bearing on the judge’s decisions, and my opinion is my own and is not the opinion of Element14. So I am going to list my three favorite projects from this challenge, and highlight my favorite update from its timeline. I would love to hear from all of my readers on which project was their favorite, and why that particular project stood out for them.

 

 

Nixie Display #8 - Controlling the nixie tubes

 

IMG_2751.JPG

 

Nixie tubes have always held a certain curiosity for me, and I think that my interest in them go back to the cold war era scifi movies I would watch as a kid that had these huge computers and control panels filled with the tubes. Im sure that it also has something to do with the ominous glow that they omit, and the retro feel they ad to an environment, but my love of Nixies is not what I am here to write about. Gerrit’s nixie display is nothing short of gorgeous and is quite ingenious in how he merged such a dated piece of technology into modern times. More importantly though, each of Gerrit’s post were very informative and full of photos, diagrams, and source code so that others could follow along at home easily. I chose his eighth update for this feature because it is a prime example of how well written Gerrit’s post are. The entire project is worth reading from beginning to end, but if you only have time to check out one of the many entries, this one is the one you should read.

 

 

Upcycled Clock – Summary

 

 

Clocks have long been one of the household items that I felt needed an update to bring them into something more than a single function role. There are companies making smart clocks that can answer your questions via a voice assistant, and others that can mimic the rising sun with RGB LED technology, but there has been a serious lack of innovation around clocks in the DIY / Maker scene. This is why Carmelito’s project was such a wonderful breath of fresh air to me. With integration such as weather and traffic monitoring, email and twitter notifications, and adding a voice assistant made this project really stand out, and ultimately is why this project was chosen as the grand prize winner. Much like Gerrit Polder’s project, every update was on point, and featured all of the elements that make a great update. I have spent almost an hour trying to decide which post from this project to feature, and in the end, I am not able to come to a conclusion, so I decided to share it’s summary post, so check it out!

 

 

Interactive Race Car Driver - Furby Hacking

Furby’s are one of the coolest and creepiest consumer toys that has been released in the last two decades, and Andy Clark (workshopshed) has shared his autopsy of one of the creepy little mechatronic creatures in one of his updates to project Interactive Race Car Driver. If any of the current, or future challengers are wondering how to structure their project, Andy has done an excellent job with this project. His post are informative, and filled with information, as well as research sources, something that I absolutely love seeing! I must say though, I am a little envious of Andy, as I would love to get my hands on one of these little guys to hack on a bit. Before losing my home to a fire in 2012, I had been collecting Furby’s with the intent of hacking them to small X-Mod RC Cars and trying to make them swarm when near each other. Unfortunately that project died with the rest of my lab in the fire. I may return to it someday still though. Head over to the link above for Andy’s full autopsy of the Furby!

Final Thoughts

 

I have been writing about DIY electronics, electrical engineering, makers, and DIYers for over a decade now, and the projects that appear in these design challenges always seem to amaze me. It’s not just the actual projects themselves, but it's also the people who make the projects that make them so intriguing. As a content creator, and someone who builds projects just to document their build, I understand how daunting of a task it can be to produce a weekly update to that project that includes photos, code, and thorough explanations of what you accomplished over the last several days. Its not an easy thing to do, and Murphy’s law is always present when trying to build a project from scratch. This is why I have so much respect for each challenger who completes their project, or at least attempts to post weekly updates.

 

I want to take a moment and thank everyone who participated in this challenge. Logging in every week and seeing that there were 10+ updates posted was an amazing feeling, and it let me know that these challenges are so much more than just a list of cool projects. They are filled with amazing people who are part of a wonderful community, and are also a source of inspiration, education, and entertainment for so many. So with that, I tip my hat to all of the challengers who left me absolutely astonished at the level of talent and intelligence we have here at Element14 who are willing to share their knowledge and tackle fairly large projects with ease.

 

With that said, I am going to end my coverage of the Up-Cycle It Design Challenge here. Thank you for returning every week to read my updates, and for cheering on the challenger's time and time again! We truly are a community here at Element14, and these challenges and their participants are proof of that. I’ll be back in a few weeks when the next challenge kicks off, so until then, remember to Hack The World and Make Awesome!
