From the project

Custom adapter PCB for the 3D volumetric display project, based on and modified from the Active-3 adapter by Henner Zeller (part of the rpi-rgb-led-matrix project).

Custom adapter PCB for the 3D volumetric display project, based on and modified from the Active-3 adapter by Henner Zeller (part of the rpi-rgb-led-matrix project).

The original Active-3 design supports up to 3 panel chains with 4x 74HCT245 ICs. This version was modified for the volumetric display rotor:

- Reduced from 3 HUB75 outputs to 2 (matching the dual-panel rotating arm) - Reduced from 4x to 3x 74HCT245 ICs - Reworked board outline to fit inside the 3D-printed rotor core - Added JST-XH 3-pin socket for photo-interrupter connection - Added JST-XH 2-pin socket for DC-DC 5V power input…
