Process

Illustration

Initial proof of concept was sketched using an iPad and an Apple Pencil in Pixelmator. The final vector-based Illustration was also done on an iPad in Vectornator.

Wood work

The sign was built from 3/4 inch ACX plywood. The design was transferred from computer onto the plywood with a projector. It was then meticulously cut by hand with a jigsaw.

LEDs

Two separate strips of SK6812 LEDs light this piece. Each strip consists of about 85 LEDs. The LEDs are controlled by a Seeed XIAO RP2040 microcontroller and they were sequenced in CircuitPython. Asynchronous I/O was required to sequence both strips of lights simultaneously from the same microcontroller.

The outer strip uses a standard rainbow fade. The inner strip uses recursion to mimic fire/candle light. The recursion is used to make a fractal of the brightness over time - which is what gives it the simulated flickering effect of fire.
