Welcome to another installment in the Design Challenge Weekly Summary series here at Element14! It’s week four 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.



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 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.



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