`Hello everyone, and welcome back to another weekly design challenge summary. It’s week seven of the Design for a Cause Challenge and a lot of progress has been made, so lets cut to the chase and learn more about the challenge before we get to our first three featured project updates!

 

Design for a Cause Design Challenge

 

The Challenge

 

Featured as the third Design Challenge of 2018, this challenge task its participants with designing a piece of assistive technology for individuals living with physical or mental impairments using the Arduino MKR1000 Dev Board.

 

 

While sixteen project proposals were chosen to be the official projects of the challenge, entering the challenge is not limited to just those sixteen community members. Anyone can join the Challenge as a non-sponsored Challenger, and still be eligible to win one of the prize packs. If you are a non-sponsored challenger all you need to do is integrate an Arduino MKR1000 into your project, and then post 10 blogs about your progress in the Design For a Cause Challenge space and then tagging those blogs 'Design for a Cause'.

 

 

The Official Kit

 

As mentioned earlier, the Design for a Cause Challenge is sponsored by Arduino and its Arduino MKR1000 Development Board. Each challenger will receive all of the components below plus a wide assortment of additional passive, and digital components to build their projects with. If you would like to enter the challenge for yourself, or if you just want to follow along at home, you can purchase all of the components in the kit right here at Element14.

 

 

To learn more about each of these components as well as the other components included in the kit, visit the official kit announcement page or click the links above.

The Prizes

To reward the creativity and innovation of the challengers in the Design for a Cause Challenge, element14 is offering some cool prizes that both sponsored and non-sponsored finishers can win. To learn more about each prize pack, visit the official Design For a Cause Challenge Prize Page.

      • Grand Prize: $900 USD to the winner’s favorite charity,  FLUKE 279 FC/IFLEX Digital Multimeter, and a  Tinkerkit Braccio Robotic Arm DIY Kit.
      • Runner-Up Prize:$500 USD to the winner’s favorite charity Tenma  72-8474 Oscilloscope and a Microduino Quadcopter w/Joypad
      • Finisher Prize:  It’s a surprise! To be eligible, challengers have to post at least 10 update blogs and use an Arduino MKR1000 in their design.

 

 

The Past Week In Review

 

Over the past 7 days, August 19th - August 25th, we have had a total of seven updates posted across six projects. I’m going to pick a couple of my favorite updates from the week and highlight them below, but before we get into that let's take a look at which projects were updated this week!

 

 

This Week’s Top Updates

 

Project: Fingerprint Skeleton Key - Design for a Cause Challenge Blog  #6 - Slider mechanism part 2

 

 

Getting things started this week is Milos Rasic and his project, Fingerprint Skeleton Key. Following up on his work in the project’s second update, Milos continued development work on the slider mechnisim that will move the key into position when it is needed. 

Instead of working with metal this time, Milos opted to use plywood as he had limited access to a 3D Printer, and because it is much easier to work with than the metal he used in his previous attempt. “I am keeping with a pretty similar design compared to the first attempt but with less screws. First thing we need are 4 identical pieces 70x30x3 mm each. The prototype I'm making will be housing 3 keys and for now we will need 2 holes on one of the shorter sides of the part. Here are the final cut and drilled pieces,” he wrote.



Project: SeeingEyeduino - Design for a Cause Challenge Blog  #7 - Assembling the project

 

 

Dale Windhild is back in my spotlight with the seventh update to his project, Seeing Eyeduino. The focus of this week’s blog was the assembly of the project’s main systems, marking a major milestone in the project’s development. Using a breadboard, and a handfull of jumper wires, the electronics quickly came together, which means that Dale has just a few task left to complete before the project is finished. “In the past week I have made up most of the remaining parts for my project. The Braille finger pad was the most important part of this project,” he wrote.  “I attached the Arduino to a breadboard to make it easier for attaching the wiring. On the other end of the breadboard is the L298 IC motor controller”


That is going to wrap up my weekly summary coverage of the Design For a Cause Challenge. Check back each week for a complete summary of the previous week's updates. If you would like to learn more about that challenge, and to see what progress has already been made, head over to its official challenge page. I'll be back next week for another installment of my Design Challenge Weekly Summary series here at Element14.
