Welcome to another installment in the Design Challenge Weekly Summary series here at Element14!  We have officially wrapped up the first week of the Safe and Sound Wearables Design Challenge, things are already off to a great start. Before we jump into this week's updates, I want to remind everyone that we are currently accepting project applications for the Upcycle It Design Challenge with Intel Edison. The application process closes on March 3rd at 23:59 GMT, so you still have some time to get your proposal together! Now that we have those bases covered, let's jump right into this week’s updates!


Before we get into the meat of today’s post, I want to take a moment and clarify a decision I made to change the date range of which I base these post. My goal each week is to publish a new weekly summary post every Monday, and with the previous range of Monday through Sunday, I simply had too little time to read through every project update and still get my summary post out by Monday evening. It caused me to get very behind on weeks where we had an abundance of post, and that is why I now use Sunday through Saturday as the range for each weeks summary. This gives me an extra day to make sure I have read everything, and craft a well written post. I apologize for any confusion this created last week, and I should have clarified why I changed the date range in my post.


I also wanted to reiterate a few things for those who are new to my weekly summary series. These post have no bearing on the outcome of the challenge in terms of judging the eventual winners. I simply write these post to help community members and other readers quickly process which projects were updated over the past week, and to showcase a few projects that I felt had exceptional updates that week.


Now that we have those bases covered, let's jump right into this week’s updates!


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, February 19-25, we have had a total of twelve updates posted across nine 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


Hearing Guard System #1: Introduction to Project




Over the years, Jon Morss (jomoenginer has noticed that laboratory and data center employees often suffer from hearing loss from prolonged exposure to the equipment that is present in those types of environments. Citing a CDC report, more than 22 million Americans are exposed to potentially damaging noise each year, with more than 10 million who already suffer from hearing loss due to exposure to these types of noise. Unfortunately, those who already suffer from some form of hearing loss will not be able to identify noise levels that could continue to damage their hearing. In his project intro, Jon lays out his plans to create a wearable device that will help solve this issue by alerting its wearer whenever they enter into an environment that contains noise levels high enough to damage one’s hearing.



Invisible Hazardous Environmental Factors Monitoring System - blog 3




While working out how he plans on measuring the UVA and UVB radiation that is present on any particular day, Douglas (dougw) realized that the sensor he planned on using was not very sensitive to UV levels in sunlight, and that his project would require the signal coming from the UV sensor module to be amplified to provide a signal that can be measured properly. To do this, Douglas used a simple general purpose offset and gain adjustment circuit which utilizes a Texas Instruments TLV433 Quad op-ampTexas Instruments TLV433 Quad op-amp. This circuit will eventually become one of the five sensors that will reside on a custom booster pack for the Texas Instruments MSP-EXP432P401R LaunchPadMSP-EXP432P401R LaunchPad.



Winter Survival Suit Post #1 (Introduction)




Dale Winhold (dwinhold) jump started his project, Winter Survival Suit, this week with its introduction post. The project focuses around building a wearable suit that is able to monitor your body temperature in several locations, and then turn on a heating system that will warm just the part of your body that drops below a predetermined temperature. A MSP-EXP432P401RMSP-EXP432P401R will monitor the sensors and control the heat while a 430BOOST-SHARP96430BOOST-SHARP96 will display the information to the person wearing the suit.


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!
