Better WLED LEDMap Generator

Code to create a WLED LED-Map (the JSON that tells WLED the positions of the LEDs) with some features that I didn’t find in any online editors: Dragging the mouse over the canvas fills all hovered cells, rescaling the map to a different size, inverting, and inserting LEDs in between existing ones.

Relay-Boxes

A universal relay box for interactive builds: Ethernet-controlled with an integrated PSU, switching 230V, 12V, 5V and dry relays via OSC or Art-Net. I use it across projects like my Supertuxkart and the Palapa Spaceship to drive lights, fog, motors, and effects with simple, robust control.
