Voxel Driver Base 16x16 RGB

Drive base for controlling 16 x 16 RGB matrix through PCIE slot.
This project was inspired by a youtuber called "mitxela".
Here is the link to the original design: https://youtu.be/HKpBhE7QVAI?feature=shared 

My version of the design had two main goals;
      1. Make it run off external power source
      2. Expand the capability of the display with RGB and double the amount of pixels.

How it works: 
1 x RP2040 Drives the Column P channel high side FET
3 x RP2040 for sinking current on each row colour
Wireless phone charging coils feed power to the drive base pcb.
A CD drive motor is mounted to the drive base pcb.
CD drive motor shaft is fixed to a mount with the charging coil and 5V power source.
Whole assembly rotates around mount point, rpm is determined by the IR feedback pulse.

Boards from JLCPCB arrived and built up a quick prototype assembly with qi coils, RF-300 motor, and a brass shaft coupler.

Qi Coil:

Motor:



IR Sensor:


Shaft Coupler: (2 to 5mm I chose, depends what you mount to)

Solder parts together, then mounted with hotglue because I really wanted to see it light up haha.

Almost looks like a Christmas tree running some buggy unsync'd code

**Currently working on code for volumetric persistence of vision display animations.**

 **Improvements to be made **:
1. use the hardware uart # properly on the column driver chip for potentially better performance
