Welcome to another installment in the Design Challenge Weekly Summary series here at Element14! It’s week thirteen of the Safe and Sound Wearables Design Challenge and this week also marks the ninth week of the Upcycle it Design Challenge. Project updates were again a little light this week in the Safe and Sound challenge, while the participants in the UpCycle It challenge continued with another solid week of updates across several projects. We have a lot to cover, so let's just jump right into it.

 

 

Safe & Sound Design Challenge

 

Featured as the first design challenge of 2017, the Safe & Sound Wearables challenge tasks its participants to conceive and build a 'safe and sound’ wearable that protects a person from personal and environmental risks, or monitors personal health or protects personal property from theft.

 

 

 

The Official Kit, and The Prizes

On February 14th 2017 Element14 announced the list of the official 15 challengers picked to participate in the challenge, and those 15 challengers received a kit of components to use in their design which was sponsored by Texas Instruments. Each kit contains the following items:

 

Participation in this challenge is not limited to the sponsored challengers however. Anyone can enter, and all they have to do is Design with TI - integrating Texas Instruments’ latest microcontroller (MSP-EXP432P401R) MSP-EXP432P401R LaunchPadMSP-EXP432P401R LaunchPad into a wearable that is Safe & Sound.

 

 

The Past Week In Review

 

In the past week, May 7 - May 13, we have had a total of three updates posted across three  individual projects. As with each of my updates, I like to highlight at least three of the past week’s updates, but with just three updates this week I will be highlighting just two of these projects. Before we get to that, let's take a quick look at which projects were updated in the past seven days.

 

 

This Week’s Top Updates

 

    • Environmental Factors - GAS Sensors - blog 16

Returning for the second week in a row to this list is project Elemental Factors by Douglas Wong (dougw). This week Doug managed to get an update out despite being sick, and to get his sensor booster pack assembled and stacked with each of the modules that make up the sensor portion of his project. “The black module on the left is the CO2 sensor, at the bottom is the UV sensor, the orange sensor is an MQ3 (alcohol), the red sensor is an MQ7 (carbon monoxide), and the stainless sensor is an MQ135 (air quality). The 3 sensors at the right are in sockets, allowing any MQ sensor to be substituted. The pots allow me to adjust offset and gain of each signal to get the best range out of the A/D,” he said. Head over to the link above to read the full update.

 

 

    • Trackable Safety Helmet for Miners #8: ADXL345 Driver for MSP432

Project Trackable Safety Helemt For Miners by Mehmet Bozdal (mbozdal) received its eighth update this week with progress on getting the ADXL345ADXL345 working with the MSP432MSP432 that is the center of his project. “I modified the Sparkfun Arduino library for the MSP432 with the minimum setting. First, we need to wake-up accelerometer and tell it to take measurements. This is done sending commands to POWER_CTL register. Second, we need to set the range of the sensor. The range varies from 2g to 16g,” he said. “The more the range the less the sensitivity. I prefer the sensitivity so set it to 2g which is the default value. I may change this values when I embed the design inside the helmet and take real scenario measurements.” Check out the full post and read over the code examples that Mehmet has provided at the link above!

 

Upcycle It Design Challenge

 

About The Challenge

 

Featured as the second design challenge of 2017, the Upcycle It design challenge tasks its participants to upcycle 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 Official Kit, and The Prizes

 

Challengers will build their projects using an official assortment of parts from Arduino, Intel, and Element14. Each kit contains the following items:

 

The Upcycle it Design Challenge features 15 official challengers that received a Challenger Kit for FREE, but thereafter anyone can join the Challenge simply by posting in the Upcycle it space (tagging their blogs 'upcycle it') to be in with a chance to win prizes. Anyone completing a project by the June 4th deadline and posting at least 10 times on the Community detailing their project build will be in the running to win some awesome prizes, including a Keithley DMM7510 Digital MultimeterKeithley DMM7510 Digital Multimeter worth almost $4,000.

 

*The official Challengers must build their project in accordance with the challenge's terms and conditions. All projects must include the Intel® Edison.

The Past Week In Review

 

In the past week, April 6 - May 13, we have had a total of nine updates posted across seven projects. With so many projects this week I will be highlighting three that I found helpful, educational, or just interesting in general. Before we get to this week’s highlighted post,let's take a quick look at which projects were updated in the past seven days.

 

This Week’s Top Updates

 

 

    • Commute time to work using Google Maps API

 

 

With a long work commute on his mind, Carmelito Andraded (carmelito) showed his readers this week how he planned on using his upcycled clock to give him a visual and audible indication of when he should leave for work to avoid traffic issues in his area. “If you live in California, specifically in Los Angeles and the surrounding counties you soon realize that the area has a huge traffic problem, which meant I had to find a more visual way of identifying, what is the ideal time to leave for work, which is normally a 25 to 30 mins commute on a good day,” he said. “The idea here is that as part of the final setup we are going to replace one of the mirror panels with a 3D printed part which diffuses the LEDs. Here is a quick video that demo’s the setup and I am using eSpeak to read out the time to work.” Check out the full post at the link above!

 

 

    • Nixie Display #9 - Hardware hacking

It’s been a couple of weeks since I featured the progress being made on project Nixie Display, and Gerrit Polder (gpolder)has made some very nice progress! This week he set out to switch over to the smaller Intel Edison module, but ran into some issues with the logic level voltages. To fix this issue, Gerrit hacked in a 5V sparkfun logic level shifter board to bump up the 1.8v signal from the edison. “The GPIO levels of the Mini Breakout Board are 1.8V, instead of 5V like with the Edison Kit for Arduino and GROVE kit. So first action was to select and order logic level converters,” Polder said. “After some digging on the internet I found a couple of links to a Sparkfun bi-directional level converter with four channels which according to the references works for the Edison…” The link above will take you to the full update where you can find more info on using a logic level shifter with the Edison as well as a few other updates to the project.

 

 

    • Interactive Race Car Driver - Hotrodding the Edison

My final featured update this week comes from Andy Clark (Workshopshed) and his project, Interactive Race Car Driver. While this update was not a very technical one, it just might be the first time in maker history that someone has added some very cool looking hot-rod header pipes to a development board! Using his 3D printer, Andy crafted up a set of faux exhaust pipe headers to give his Edison board a more sporty feel, and to better tie it aesthetically into the project. Head over to the link above to read the full update and to download the printable file for the exhaust headers!

 

 

That is going to wrap up things for this week. Remember to check back next week for another Design Challenge Weekly Summary post. Until then head over to the official Safe & Sound Wearables Challenge Page, as well as the Upcycle It Challenge’s landing page fore more Design Challenge content! As always, remember to hack the world and make awesome!
