PiCasso Design Challenge

I have reached the conclusion of the Picasso Challenge and I must say it has be quite a challenge journey!. I enjoyed so much working on this project where I learned tons of new things and it gave me the opportunity to stay in touch with awesome members of the Element14 community. I'd like to take this opportunity to present one more Hologram demo, hope you enjoy it!. Warning: The following video contains loud sounds   Bill of Materials Electronics Assembly Other 3D ...
Initializing the Addressable LEDs Before doing any programming, one important step of the process is to initialize the the WS2812B as they will turn on each time power is connect to the Raspberry Pi. The easiest thing to do here is to write a simple Python program that will be executed every time the Pi boots, initializing (turning off) the Addressable RGB LEDs without requiring a manual script run.   Editing rc.local The rc utility is the command script which controls the automatic boot pr ...
I'm finally heading to the conclusion of this project which I have enjoyed beginning-to-end. Essentially this project will use a Raspberry Pi 3B+ and a Raspberry Pi Touch Display to work, but I've added as a bonus a few custom made PCBs and will add a Camera Module V2 to try making it more interesting.   The custom made PCBs have arrived which means is time to gather all the components needed and to start assembling the electronics!.

I'm really excited at this point as the project is nearly finished. While the PCBs are being manufactured is time to paint the 3D printed parts!. To paint the 3d printed parts I have chosen Matte finish Black paint (some times known also as Flat finish); Black will be the perfect background color for the hologram projections and a matte finish will reduce any reflection to the minimum, also will provide the entire project a a better overall look.

After a successful Pepper's Ghost test, my next step in the project build is to work with some of the electronics.   When I was researching and collecting ideas to include in the design of the Hologram Pi-ramid, I really wanted it to be able to work in a similar fashion to the 2D/3D Holographic Displays commercially available, where the holographic 3D content (visual effects, animations, information) is combined with a physical object placed inside the hologram generator; this is perhaps t ...
In a previous project update, I described the process of building a simple Plexiglass Pyramid essential for this project to come alive. I'm very excited now to show to my fellow readers my firsts tests of a Hologram like projection based on the Pepper's Ghost principle; it was very difficult to find proper animations of objects from different angles to show what can be done with this kind of project so I had to come with my own approach -without expending too much time in this test-.   Whi ...
I'm very excited about the progress of the Hologram Pi-ramid. At this point I'm just one step away of testing the Pepper's Ghost principle.   In the previous blog post, I've covered the 3d printed parts and some assembly. Such parts will help in the construction of the Plexiglass pyramid too as they will provide support when gluing the pyramid which is made of 3 pieces of 2mm thick (0.08 inches) clear Acrylic -also known as Plexiglass among many other names. To cut the Plexiglass I used ...
Once I was happy with all necessary the details in my project design, I started 3d-printing all the parts required to begin testing the assembly which overall is looking really good!.   3-D Print settings Below the settings used: Printer: Creality CR-10S -a big thanks to Element14 for this awesome price! Material: PLA Blue-denim Infill: 15%, triangles Adhesion: Brim Supports: No Layer height: 0.2mm   Assembly and materials required It didn't make much sense to me to incorpora ...
Following up the initial design of the Hologram Pi-ramid, the next step that made sense to me was to start designing the project in a 3D CAD/CAM software; this allows me to get a feeling on how the project should look like, make adjustments, corrections and most importantly, I wanted to measure the dimensions of each side of the Plexiglass pyramid once it was defined within the project.   I started by finding mechanical drawings of the key components like the Raspberry Pi 3B+ and the 7" To ...
While I was looking for inspiration to bring and idea to life for the PiCasso Design Challenge I came across something clever, really unique and something I really wanted to try for myself once I understood how it worked: A Hologram-like projection using the Pepper's ghost principle.   Using the Pepper's ghost principle one can create a 3-D illusion displaying symmetrically opposite images that seem to float in mid-air and which are visible from different angles, this by no means is a 3-D ...
