With another year behind us, we are once again at the beginning of a new design challenge season here at Element14. Week two 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:

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 21st - January 27th, we have had a total of eleven updates posted across nine 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: Bake Mate - Pi Chef Challenge Blog post #1 - Introduction



My first featured post for this week happens to be the first update blog for project Bake Mate, by Avner Fernandes (avnrdf) who has identified several issues that often cause issues with how a recipe turns out. Most of these issues stem from flawed unit conversions that can be complicated for some people to do on the fly. To remedy these issues, Avner will build a device that will allow chefs and bakers to precisely measure out the correct amount of ingredients needed to properly prepare any recipe of their choosing. To do this he will use a Raspberry Pi 3, 2.4-inch touchscreen, a load cell for measuring weight, and a thermocouple for measuring temperature.


Normally, I try to not feature intro post but I really liked the way this post was laid out, and I felt that it actually explained the issue he has identified, as well as his  solution to that issue. The flowchart was easy to follow, and his explanation of each component of the system was clear and concise. This is exactly what I like to see in an intro post, and hope that it will help future challengers understand what makes a great introduction post by me highlighting it here.



Project: The Spice of Pi - Blog Doug 2 & The Spice of Pi - Blog Glenn #1




My next highlight for this week is actually about two separate blog post for the same project but by two different people, neither of whom are in the official challenger list I might add. I have said many times that I love seeing challengers collaborate with each other as well as other community members, and I think that our old friend Douglas Wong (dougw) and Glenn Vander Veer(glennvanderveer) took this in its most literal form. Doug and Glenn have teamed up to compete in this challenge and to test the age old theory that two heads are better than one. Doug will be handling the hardware side of things while Glenn will be working on the code for the most part.


So what are they building you ask? If you have followed Doug’s other design challenge projects I am sure you are just as curious as I was, so I won't spoil the surprise, and you will just have to check out the project’s introduction post. I will tell you that I am excited to see how it turns out, and may be implementing this one in my own kitchen.



Humble Bundle - Sous Geek Cookbooks



My final highlight of the week is not a project but a post from Element14’s own Phil Hutchinson (e14phil) that clued us all in on a sweet collection of geeky cookbooks that are on sale in the latest Humble Bundle. “For the uninitiated The Humble brand/website is a charitable method of publishing your Games, Ebooks or other digital media,” he wrote. “Every month Humble compile a different set of themed Games or eBooks that you buy starting at $1+, you then choose what percentage of your purchase goes to charity and what goes to the chosen charity for that bundle.”


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. 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!
