I own a lot of HATs for my Raspberry Pi. Between the Unicorn HAT, Scroll pHAT and Blinkt! you might say I’m addicted to LEDs but I’ve recently managed to find a new addiction in 3D printing.
Whilst the Unicorn HAT is a lovely, colourful, 8×8 matrix, the individual NeoPixels are naturally round and quite bright. Needing to get to grips with our Maker Space’s 3D printer I decided a good first project would be a diffuser that would turn those circular LEDs into square ‘pixels’.
