Hello everyone, and welcome back to another weekly design challenge summary. It’s the eighth 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, 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.


The Prizes

      • 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.

The Past Week In Review


Over the past several days, April 28th - May 4th, we have had a total of seventeen updates posted across eleven projects. I will be highlighting three of my favorite updates from this past week, but before I get to that, let's take a look at which projects were updated. 



This Week’s Top Updates


Project: PiCasso Adapting Art to Viewers - PiCasso Design Challenge Blog  #9 - Displaying Art



Claiming the top spot this week is the ninth update to project Adapting Art to Viewers by Frank Milburn. In this update Frank walks us through his implementation of the Pi Presents software, and how he is using a separate Raspberry Pi to handle the facial recognition portion of the project and a second Raspberry Pi to manage all of the audio and video display functionality. “ I did a search for existing software and found Pi Presents, "a toolkit for producing interactive multimedia applications for museums, visitor centers, and more", He wrote. “It is Python-based.  The video player uses omxplayer with all supported formats, and the image player supports all formats in the Python Imaging Library.  It also includes a message player and audio player.  Numerous working examples that demonstrate the capabilities are included.”  Head over to the link above to read the full update, and to watch a short demonstration video of the facial recognition working, and how it will trigger the art adaptation events.



Project: Kinetic Art Mobile - PiCasso Design Challenge Blog  #5 - Finally a PCB Design



Our second feature update this week comes from project Kinetic Art Mobile, by Gene Breniman. After four interesting updates, Gene has finished the custom PCB design that will power the kinetic mobile. The design utilizes an Atmega168 as well as Bluetooth connectivity, a fan controller, and an accelerometer/compass. This PCB also features several large holes to help aid in airflow over the PCB. Additionally a few LED PCBs were designed as well. “The Main PCB is riddled with 12 - 0.1" holes to allow additional airflow, through the board, into the fans below (there will also be some airflow around the board edges).  I will be trimming the PCB into a circle, as my PCB vendor (lower cost) only allows for rectangular boards,” he wrote. “The LED boards are sort of a universal design that will be connected to the main PCB, providing pairs of  LEDs along the circumference of orb and a single LED providing downward lighting (right angle mounted, hacked LED PCB).  This will provide me with 18 - fully programmable RGB LED to illuminate the sides and bottom of the orbs.” Check out the full update at the link above.



Project: PiMassive - PiCasso Design Challenge Blog #2 - CNC Time



Claiming our final spot this week is a project I am very interested in seeing completed, project PiMassive. In the projects second update Wesley Gardner shares two videos of his home-made CNC router carving out the massive Raspberry Pi body out of a sheet of plywood. “So the program I am using for carving is Vectric VCarve Pro and the CNC I will be using is my MPCNC version 1 which has gotten a ton of revisions in the last 4 years but mine is still going strong so no sense in upgrading it quite yet.   Certainly will be making a newer one for a laser engraver in the future,” he wrote. After watching both of the videos, and having a CNC router of my own, I think I may have to follow Wesley’s lead and make one of these myself for my lab’s wall. Head over to the full update at the link above to watch both videos, it's definitely worth your time!



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. Check back next week for another weekly design challenge summary.
