Welcome to another installment in the Design Challenge Weekly Summary series here at Element14! It’s week six of the IoT On Wheels Challenge, and things are getting off to a great start. 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 15 - October 21, we have had a total of six updates posted across five 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: The Konker Connection - Blog 4



In his fourth update, Douglas Wong (dougw) began tackling some serious issues that have arose in project The Konker Connection. The first issue Doug tackled was with the gas tank level sensor, followed by him designing a custom interface PCB that would implement all of the features of his design. If you have followed these weekly update post, you know that I am a sucker for custom PCBs in projects, and Doug never seems to disappoint. Head over to the link above to see how he is tackling the gas tank issue, and a more indepth description of the custom PCB.



Project: CycleOps Blog #4 - Finally We Get To IoT



After doing some research, and obtaining a free $100 voucher at a tech conference, Parker Ellwanger (rpbruiser) made the decision to use Microsoft’s Azure platform as the foundation of his project. After creating an IoT Hub, Event Hub, and Device Provisioning Service, Parker was able to get the connection string and API keys he needed to begin connecting his project to the web. The post is a little lacking in information about the process, but it does help to open up others to the idea of using Azure for their projects as well. Wrapping things up, Parket also shared a link to his Github repository at which you can find the files he is modifying for this project. Head over to the link above to grab that link.



Project Walking Wheels on Water#10 Create Mobile APP for  X-NUCLEO-IDB05A1X-NUCLEO-IDB05A1 blewrite control LED on/off



Our final highlight this week comes from project Walking Wheels on Water by F. Yao (fyaocn). In the project’s tenth update F. Yao detailed how he created a mobile app that would eventually be able to control Flywheels, the small airplane he has built as part of the project. As always, he has created a wonderfully detailed post, with the full source code being available for inspection and download at the link above. I would like to urge all of the challengers to include the source code they write in their blog post just like this as it helps those of us following along at home better understand what is happening.



That is going to wrap up things for this week, tune in next week for another Design Challenge Summary. 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!
