Welcome to another installment in the Design Challenge Weekly Summary series here at Element14! It’s week eight of the IoT On Wheels Challenge, and the project updates continue to roll in. Before we jump into the challenge, you should take a moment and read my intro post that will fill you in on the full details of the challenge as well as the challengers who are competing to win some amazing prizes. Additionally, there will be a listing at the bottom of this post with links to my previous coverage of this challenge.


IoT On Wheels Design Challenge



About The Challenge



Featured as the third design challenge of 2017, the IoT On Wheels Design Challenge opened for project idea submissions in June of 2017, which was met with many submissions from community members. As I mentioned earlier, the challenge is based around the NUCLEO-L476RG development boardNUCLEO-L476RG development board which is built on the STM32L4STM32L4 Arm Cortex M4 line of processors. Challengers have ten weeks to develop their project, and share their progress in a series of weekly update post. By posting a minimum of ten update post, challengers become eligible to win several awesome prizes, and the chance to become one of our prestigious design challenge winners.



Entering the challenge is not limited to just the ten chosen community members though,  anyone can join the Challenge as a non-sponsored Challenger. Here's how: Simply get the low-cost NUCLEO-L476RGNUCLEO-L476RG and integrate it into your project, as well as post 10 blogs about your design journey in the IoT on Wheels space (tagging your blogs 'IoT on Wheels'). All Challengers must build their projects in accordance with the Challenge's terms and conditions and all projects must include the  NUCLEO-L476RGNUCLEO-L476RG



The Official Kit, and The Prizes



On September 4th, 2017 Element14 announced which 10 community members were picked to participate in this challenge, and those 10 challengers received a kit of sponsored components to use in their design which was sponsored by STMicroelectronics. Each kit contains the following items:



To learn more about each of these components or to purchase them to use in your own project, visit the official kit announcement at the links above.


Each challenger is competing to win one of three prize packs that feature prizes ranging from a Segway Mini Pro, to an Oculus Rift VR headset, Bicycle GPS system, GoPro Hero 5, and even a radio controlled hobby truck. Other prizes include tools from Duratool, a bench power supply, and even a high end pair of headphones. All challengers who complete ten blog post and finish their project will also receive a prize pack including a tool kit from Duratool, a heat gun, and digital multi-meter. These prizes are open to all who enter the challenge, despite not being an official challenger, with the requirements being the same: Use a STMicro NUCLEO-L47RG and post ten blog post by the challenge’s deadline on November 13th.



The Past Week In Review


Over the past 7 days, October 29 - November 4th, we have had a total of nine updates posted across six projects. Before we get to my highlights for this week, let's take a look at which projects were updated this week!




This Week’s Top Updates



Project: Smart Drive - Connecting GPS - Blog #5



Our first featured update this week is from Sergei Vlasov (vlasov01). In his projects fifth update, Sergei shows us how he integrated GPS into the Smart Drive system. “I've purchased a GPS module VK2828U7G5LF. It is based on UBX-M8030-KT chip, antenna and UART interface,” he said... “It was my first experience working with GPS module. I'm generally happy with results so far.The next steps is to explore STM32L47RG serial interface and connect it to GPS module." Check out the full post a the link above to read more, and to view the source code Sergei provided.



Project Walking Wheels on Water  #12 Motor Driver L298N for N30 DC motor



In his project’s twelfth update, F. Yao (fyaocn) showcases how he plans to drive the hobby motors that will be used to propel the project in the water. Using a L298N H-Bridge motor driver to power a N30 motor with a 75mm propeller attached. The motor driver will use a 5V source that will be provided by four AAA batteries. Head over to the link above for more info.



Project: Traffic Predictor #10 - Evading traffic like a Bat



Our final featured project for this week is, project Traffic Predictor by Dixon Selvan (dixon415).  In his project’s tenth update, Dixon shows off one of the coolest user interfaces I have seen in one of our design challenges. Using an ultrasonic sensor that is mounted to a servo, he has created a sort of 180-degree radar that will allow more autonomy in the autopilot he is designing. Head over to the link above for the full rundown, and a demo.



That is going to wrap up things for this week, tune in next week for another Design Challenge Summary. I apologize if this weeks update was a little short, as well as a little late. I have been battling a fairly bad cold for the last few days, and have not been able to muster up the strength to finish editing this until today. If you would like to learn more about this challenge, and to see what progress has already been made, head over to the its official challenge page, and as always, remember to hack the world and make awesome!
