… or what you get if you video concentric RGB LED rings and put them out of focus.

No shortage of lens flare here

taking the whole proto-plate thing a bit far …

Yes, it’s a very tiny microcontroller board and breadboard doohickey. The board’s a Trinket M0 running CircuitPython 2.0. The base is laser-cut birch ply. Definitely #smol  at less than 75 × 55 mm …

Here’s the SVG for laser cutting:
To build it, you’ll need:

  • 3 mm birch ply (at least 75 mm × 55 mm)
  • Adafruit Trinket M0
  • Tiny breadboard: either a tiny or a Mini one. The board markings match either.
  • M2.5 screws and standoffs
  • 4× stick-on feet
  • 2× 1×5 female header — I cut down a 1×12 female header.

If I were to redesign this, I’d:

  1. make the breadboard outline a score line rather than an etched area. Scoring is much quicker than etching.
  2. Mark pin definitions on the plate. They’re a bit hard to read on the Trinket M0.

Obligatory blinky code for running a 16 LED NeoPixel Ring and the LED in the middle of the Trinket:
