Sol v2: 420mm (16.5”) wide, 1,600+ RGB LEDs wall-mounted behind laser cut translucent black acrylic. Mapped in XY & polar coordinates, driven by an ESP8266 using the FastLED library.

Mounted on 3mm wood back plate, 3D printed inner frame to keep the LED rings evenly spaced, with M3 standoffs between the back plate and frame, and between the frame and front acrylic.

The LEDs could theoretically draw ~96A (480W @ 5V), but I’ve limited them to ~2A using FastLED’s power management. Currently powered with a small sealed 10A power supply.
