Welcome to another installment in the Design Challenge Weekly Summary series here at Element14! It’s week four of the Safe and Sound Wearables Design Challenge, and things are starting to heat up. We have a lot to cover this week so let’s just jump straight 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 5 - March 11, we have had a total of eleven 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

 

Smart Safety Glasses #2: Playing with capacitive sensing

We kick off this week’s summary with an update from Alex Kucherov’s (salexku) project, Smart Safety Glasses in which he experiments with capacitive sensing, and how it can be utilized to enable or disable a power tool. Alex built a parallel plate capacitor and then measured it’s capacitance in three different cases. This information allowed him to set up a quick test circuit using an Arduino and the CapSense library. Head over to the post at the link above for the full rundown.  

 

 

Safety Jacket for the Tolling Industry #3: TI RTOS and POSIX with the CC1310 Launchpad

 

 

Inderpreet Singh (ipv1) posted an excellent update this week and introduced us to TI RTOS and the CC1310 LaunchpadCC1310 Launchpad. Due to the CC1310’s super long RF range, and low power capabilities, he has chosen it to serve as the main modules in his project. Unfortunately programming the Arm Cortex processors on this launchpad is a little more tricky than programming a MSP430, so Inderpreet wrote and filmed an excellent tutorial on how to get started in this new and exciting realm of real time operating systems. Check it out in the video and link above!

 

 

Winter Survival Suit Post #3 (Kit unboxing)

Over the last few weeks we have seen a lot of the challengers state that their sponsorship kits have not yet been received, but as of this week, it appears that is no longer the case. Dale Winhold (dwinhold) updated us this week with an unboxing post as did a few other challengers. This means that the kits are beginning to arrive, and that everyone can soon get to building out their projects!

 

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!
