LIVE Visual Experiences:
For years I have been collecting video wall LED panels from a variety of Ebay deals, campus reuse postings, and scrapped projects. In summer 2025, I decided to finally put my collection to use to put together a (relatively) huge video wall installation to be used at events in my dorm.
Here is a video of the partial installation in action, displaying a visual sequence I set to music myself.
In order to make the installation work, this project took a huge amount of development in mechanical design, wiring and electronics, as well as two custom pieces of software.
Mechanical Design:
I had 3 types of panels in my collection, 32x16 P8 outdoor panels, 64x32 P5 indoor panels, and 64x64 P3.91 indoor panels. So I built a variety of screens using all of them. Here are the CAD models and overall layout of the whole system.
Everything was designed around aluminum extrusion so it was simple to fabricate and modular.
The P3.91 panels had steel pads glued onto the panels themselves, and no other screw holes or convenient mounting points. I had to build a frame with corresponding magnets held in the right positions to keep the P3.91 panels in place. This made for a very annoying assembly process as the magnets did not constrain the alignment of the panels, making it extremely difficult to keep everything aligned.
The P8 and P5 panels were much easier to work with, coming with threaded inserts molded into a frame that each LED PCB was screwed into. I could simply design a frame from aluminum extrusion with a variety of 3D printed pieces allowing the panels to be screwed into place with exactly the right spacing.
