Welcome to another installment in the Design Challenge Weekly Summary series here at Element14! It’s week five of the Safe and Sound Wearables Design Challenge, and this week also marks the return of my project summary series. There have been a lot of good project updates over the last week, so let's just jump 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, March 12 - March 18, we have had a total of nine updates posted across eight projects. As with all of my weekly summary post, I will select a few of my favorite updates from the week and highlight them briefly below, but first let's take a quick look at what projects were updated in the past seven days.



This Week’s Top Updates


Safety Jacket for the Tolling Industry #5: Writing your own protocol


2017-03-21 16_49_08-Safe & Sound - Safety Jacket for the Tollin... _ element14 _ Safe and Sound.png


As an engineer there will be times where you have to take matters into your own hands and write your own protocols to get the job done, and with more than a decade of experience Inderpreet Singh (ipv1) is doing just that in the fifth update to his project, Safety Jacket For The Tolling Industry. In this educational yet easy to read update, Inderpreet walks us through each step of the process he uses to create his own protocol stack. From the terminology, to the code, it’s all there. I’m positive that this post holds something inside for everyone from seasoned engineer to home hobbyist, so head over to the link above to check it out.


This post actually came at a good time for me as I am actually in the process of learning to write protocols myself, and this update really helped me wrap my head around things a bit more. That is what makes these design challenges so valuable to the community, and why I hold such a high regard for those who join the challenges and share their knowledge. Collaboration and the sharing of knowledge like this is the true driving force behind innovation, and is what makes the Element14 community so special!



Hearing Guard System #5: Audio Circuit - Part Deux



My next featured updated this week comes from Jon Morss (jomoenginer) and his project, Hearing Guard System’s fifth update. If you have been following this project, you will remember that Jon recently started work on the project’s audio circuitry. In part two we get our first glimpse of the code that will run on the MSP-EXP432P401RMSP-EXP432P401R to handle the audio task as well as controlling the 430BOOST-SHARP96430BOOST-SHARP96 LCD.



Telemetry System For Smart Clothes #2: The shirt




Alexander Molnar’s (amolnar) second update to his project, Telemetry System For Smart Clothes, earns the final spot in this week’s summary. It’s not a very large post, but I wanted to feature it because despite still not having received his sponsored kit, Alexander is continuing to push forward by working on the shirt that will hold all of his sensors. Over the course of the design challenge series we have seen many attempts to hide wiring inside of clothing, but I think that Alexander may have just set the new standard for the best way to embed wires inside of clothing. Using a unique weave pattern, he created little channels that will allow the wire to flex and move with the natural movement of the clothes when worn, a problem that has plagued wearables designers for years. Great job Alexander! Hit up the link above to check it out!



That is going to wrap up things for this week, but check back next week for another Design Challenge Weekly Summary post, as well as my first Project Summary post of this challenge. Until then head over to the official Safe & Sound Wearables Challenge Page, and as always, remember to hack the world and make awesome!
