Draft and unofficial, not affiliated with Fab Academy. Check prices, GST and parts before you buy.
Summary
A desktop mood lamp: the diffuser is cast in a silicone mould taken from your own 3D-printed master. A 12-LED ring and ESP32-C3 sit in the base; a button cycles modes and a small web page sets the colour over Wi-Fi.
What it teaches
Design a diffuser dome with a cavity for the electronics, print the master, make a two-part silicone mould (parting line, pour/vent design, release), cast in clear epoxy, finish (sand to frost), then drive a WS2812 ring from XIAO ESP32-C3 with a Wi-Fi colour picker page.
Topics it touches, in Fab Academy-style terms:
- 3D scanning and printing
- Molding and casting
- Output devices
- Embedded programming
- Networking and communications
- Computer-aided design
Safety notes
- Epoxy and silicone: work ventilated, wear nitrile gloves and eye protection, follow the supplier's mix ratio by weight.
- Do not cast electronics into epoxy; keep the LED ring in a removable base (heat and repairability).
