Welcome to another installment in the Design Challenge Weekly Summary series here at Element14! It’s week eight of the Safe and Sound Wearables Design Challenge which puts us just over half way through. Additionally, we are just wrapping up the fourth week of the Upcycle It Design Challenge which means we have a lot to cover, 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, April 2 - April 8, we have had a total of five updates posted across four projects. As with all of my weekly summary post, Since only four projects were updated, I will select a two 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.

 

Project: Hearing Guard System - by Jon Morss (jomoenginer)

Project: Winter Survival Suit Post - by Dale Winhold (dwinhold)

Project: Flooding early-warning Alarm Pack by Feng Yao (fyaocn)

Project: Invisible Hazardous Environmental Factors Monitoring System - by Douglas Wong (dougw)

 

 

This Week’s Top Updates

 

Hearing Guard System #7 CCS and TI-RTOS with Class code

 

2017-04-11 06_09_10-Start.png

 

Our first featured update this week is once again from project Hearing Guard System by Jon Morss (jomoenginer). After teaching us how to set up Code Composer Studio to support C++11 in TI-RTOS, Jon moved on to writing a few code examples to help us better understand how to use C++ Classes in a TI-RTOS project. For readers who are not very familiar with TI-RTOS and CCS, this post is definitely a must read, and is worthy of a bookmark for future reference. As many of you know, I love post like this that are educational and sample code rich. Check out the full post at the link above.

 

 

Flood early-warning Alarm Pack #4: Understanding BQ25570 EVM board

Project Flood early-warning Alarm Pack by Feng Yao (fyaocn once again claims the second featured update of the week. This we were provided with a very informative post that detailed the features of the BQ25570 EVM boardBQ25570 EVM board. “The bq25570 device is specifically designed to efficiently extract microwatts (µW) to milliwatts (mW) of power generated from a variety of high output impedance DC sources like photovoltaic (solar) or thermal electric generators (TEG) without collapsing those sources.The battery management features ensure that a rechargeable battery is not overcharged by this extracted power, with voltage boosted, or depleted beyond safe limits by a system load,” he said. “In addition to the highly efficient boosting charger, the bq25570 integrates a highly efficient, nano- power buck converter for providing a second power rail to systems such as wireless sensor networks (WSN) which have stringent power and operational demands.”

 

 

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 2 - April 8, we have had a total of twelve updates posted across ten 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

 

UpCycle It - R2I - #3 - The Kit

My first featured update for the Upcycle it challenge features none other than John Kutzschebauch (jkutzsch) and his project, UpCycle R2I. This is one of those projects that has stolen my heart and attention as it is very similar to something I have been planning to build for some time now. The idea of recycling old refrigerators into egg incubators is for lack of a better word, brilliant. As a hobby farmer myself, the idea of reusing an old appliance to help expand my flock of chickens is very interesting to me, and I will definitely be keeping a close eye on this project. Click the link above to check out this project from the beginning.

 

 

Interactive Race Car Driver - Edison

Design Challenge veteran Andy Clark (Workshopshed) claims the number two spot this week with his project, Interactive Race Car Driver. In the project’s fifth update, Andy walks us through the process of setting up the Intel Edison board, installing a few prerequisite programs, and running a quick test with MRAA. This post caught my eye due to the list of references that Andy has posted at the bottom of the update. This is something I feel that we all should do more often. Having a list of resources where we gathered our info from could prove invaluable to someone else reading our post, and wanting to further understand why we did specific things in the code, hardware, or design aesthetics. Hit up the link above for more.

 

 

Nixie Display #2 - Investigations

Out final featured update this week comes from Gerrit Polder’s (gpolder) project, Upcycled Nixie Display. After showing us how he measured the power rating of the Nixie tubes used in the project, Gerrit briefly educates us on how the numbers in each tube are indexed, and what is needed to drive the tubes. Nixie tubes are something I have always wanted to work with in a project, so I will be paying close attention to this one for sure. Follow along as well by visiting the link above.

 

 

That is going to wrap up things for this week. Remember to check back next week for another Design Challenge Weekly Summary post.
