We wanted to build a "bigger" matrix display with Neopixel stripes as a birthday present. This is the outcome.

Used parts:

  • 50x50cm picture frame
  • 50x50cm shaded acryl glas
  • 841 Neopixels (we used the 12V version)
  • 12v Powersupply able to provide at least 11A
  • ESP32 running WLED
  • metal sheet with holes
  • printed parts
  • wires
