Hello everyone, and welcome back to another weekly design challenge summary. It’s the seventh week of the PiCasso Design Challenge. Lots of progress has been made over the past week, but before we get to the good stuff, let’s take a few moments to learn more about this challenge, it’s challengers, and what hardware they are using.
PiCasso Design Challenge
About The Challenge
Featured as the first Design Challenge of 2019, this challenge task its twenty participants with creating their artistic masterpiece using a Raspberry Pi Model 3B+. Challengers can either push their boundaries by using the computing power of Pi as the brains of their artistic work or to improve the aesthetics of their surroundings.
While twenty project proposals were chosen to be the official projects of the challenge, entering the challenge is not limited to just those twenty community members. Anyone can join the Challenge as a non-sponsored Challenger, and still be eligible win one of the three prizes. If you are a non-sponsored challenger all you need to do is integrate the components from the official challenger kit into your design, and post 10-weekly blogs detailing your project’s build.
The Official Kit
The PiCasso Design Challenge is sponsored by the Raspberry Pi Foundation. 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 to purchase them for your project.
- Grand Prize: DJI Mavic 2 Pro Videography Drone
- Runner Up Prize: Nikon D3500 DSLR & Lens Kit
- Finisher Prize: Raspberry Pi Arcade Kit.
To be eligible, a challenger has to complete their project, use products from the challenger kit, and post at least 10 updates in the Sixth Sense Design Challenge space. To learn more about the prizes, head over to the PiCasso Design Challenge Prize Page.
The Past Week In Review

This Week’s Top Updates
Project: Art-a-Tronic - PiCasso Design Challenge Blog #11 - Audio Adventures and Social Media Integration
Our first featured project update this week comes from Enrico Miglino’s project, Art-a-Tronic, and focuses around giving SevenOfNin a voice of its own. Getting the audio out was fairly straight forward with Enrico utilizing the Raspberry Pi’s analog audio output and a small amplifier that would be permanently mounted in the cyborgs head. The more challenging part was giving it a voice. Instead of using text to speech software, Enrico decided to use phrases from television shows as a way to make things more interesting. “Coherently with the design of the animatronic and the environment with which it reacts and interacts Seven Of Nine speaks using sentences from film, TV series, videos and more,” he wrote. “The initial difficult has been finding a method to develop the set systematically: after searching on the net, a great help come from the site playphrase.me where you can search by word or sentence over 350k short pieces of video that you can download. Better to take a try than explain how it works.” To learn more on how this works, and to watch a video of it in action, head over to the link above.
Project: Hologram Pi-ramid - PiCasso Design Challenge Blog #4 - Plexiglass Pyramid
Claiming the second spot this week is the fourth update to project Hologram Pi-ramid by Luis Ortiz. While we all appreciate updates on the electronic hardware as well as the software segments of each project, I have a serious love for clean mechanical builds, and that is what this weeks update from Luis was all about. Using a 3D printed jig, some solvent-based glue, and some plexiglass, Luis was able to make a flawless pyramid that will be perfect for projecting a hologram onto. “To bond all the Plexiglass pieces together I used Methylene chloride, also known as dichloromethane or DCM; a fast-drying solvent that welds some plastics by softening the polymer and fusing it together, which I applied with a small blunt tip syringe allowing it to flow along the surfaces to be joined via capillary action,” he wrote. “To add support I used some of the 3d printed parts assembled together, a rubber band and a little help of gravity.” A photo of the assembled pyramid and a quick demonstration video can be found in the full post at the link above.
Project: POV Globe - PiCasso Design Challenge Blog #6 - Power Transmission
One of the things I love best about Design Challenges is observing how the challengers solve problems that arise during their projects build. What makes this so special for me is when a solution is presented that I would have never come up with. In the sixth update to project POV Globe, Dale Winhold was faced with the challenge of supplying power to the Raspberry Pi that is mounted to the rotating section of the POV globe. My solution would have been complicated, expensive, and involved a collector ring, but Dale simply supplied power to the spinning disk by feeding the power through each pole of the globe. The south pole feeds in the positive line, and the north pole feeds in the ground line giving the Raspberry Pi and LEDs a constant connection to power. Dale has included a short demonstration video at the end of the full post.
That is going to wrap up this weeks coverage of the Picasso Design Challenge. If you have not yet done so, please take a moment and check out all of this weeks updates, and show our challengers some love in the comments section of each update post.
