January has come and gone, and its week three of the Pi Chef Design Challenge and there has been a lot of new projects posting their first update blogs, but before we get started with that though, let’s take a moment to find out what this challenge is all about.


Pi Chef Design Challenge


About The Challenge


Featured as the first design challenge of 2018, the Pi Chef Design Challenge opened for project idea submissions in October of 2017, which was met with many submissions from community members. As I mentioned earlier, the challenge is based around the Raspberry Pi 3 Model BRaspberry Pi 3 Model B SBC. Challengers have eleven 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 buy  a Raspberry Pi 3 model B and integrate it into your project, as well as post 10 blogs chronicling your project’s progress into  the Pi Chef Design Challenge 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 Raspberry Pi 3 Model B.



The Official Kit, and The Prizes


On January 10, 2018 Element14 announced the 15 community members that were picked to participate in this challenge, and those challengers received a kit of sponsored components to use in their design which was based around the Raspberry Pi 3. If you would like to purchase the official kit, click here.


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 the following prizes:

Grand Prize

        • Breville Barista Express Espresso Machine
        • $1500 USD Newark element14 / Premier Farnell Cart

Third Place

        • Breville Tea Maker
        • $500 USD Newark element14 / Premier Farnell Cart


A finisher who has completed their project, used the Raspberry Pi, posted 10+ updates in the Pi Chef space and adhered to the requirements in the Terms and Conditions will receive a mystery package of element14/Premier Farnell products valued at $65 USD.



The Past Week In Review


Over the past 7 days, January 28th - February 3rd, we have had a total of thirteen updates posted across eleven projects. That is a pretty nice number for week one, so let's take a look at which projects were updated this week!



This Week’s Top Updates



Project: The Cooker Connector - Pi Chef Challenge Blog #2.5 - A Slight Change of Plans



This challenge is turning out to be filled with first. Earlier this week we were contacted by Jonathan Schooler (jschools) seeking permission to change the direction of his project. This was due to an unfortunate coincidence where the manufacturer of the temperature probes that he was using in his project has actually just released the exact project he was building. Out of respect for the company, and wanting to be unique, Jonathan has decided to modify his project and add a servo to the mix that will allow him to open and close the air vents on his smoker based on temperature fluctuation.


Being an avid smoking enthusiast myself, this project has my full attention, and I am actually quite excited to see this new addition implemented. I too have been down this road, and built my own IoT Smoker Thermometer System a couple of years back. Adding air vent control is something I have thought of adding before, so I will be interested in how Jonathan pulls it off. Head over to the link above for the full rundown of the new plans.



Project: Automatic Dough Shaper - Pi Chef Challenge Blog #3 - RPi3 setup & recipe JSON format


Sometimes I am amazed at how much I learn from each project over the course of a design challenge, and this challenge is turning out to be as equally as fruitful. While waiting on her challenger kit to arrive, AnnaLisa Davis (a_davis_22) decided to start designing the control circuit that will regulate the temperature inside the toaster oven she will use to cook her CNC cut cookies. This too is something I have played around with in the past, but AnnaLisa’s approach is much more refined than my attempt was. Head over to the full post at the link above to learn more about the circuit she built.



Project: Bake Mate - Blog #3 - RPi3 setup & recipe JSON format



Rounding things out this week is Avner Fernandes (hans_ober) with his project: Bake Mate’s third progress blog With his Raspberry Pi set up and running Avner jumped right into getting the 4DPi-24-HAT configured and working as well This task was easily accomplished with just a jumper change needed to get things working correctly This allowed work to begin on building out the system’s UI using Python and JASON Head over to the full update for more information on how each recipe will be laid out



That is going to wrap up this weekly summary of the Pi Chef Design Challenge. Remember to check back each and every week for the duration of this challenge for a summary post from the previous week’s updates. I apologize for a short post this week, I unfortunately have been battling something between a cold and the flu for a couple of weeks. 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!
