The Only Cat That Won’t Chew Your Wires
Build a 3D-printed, ESPHome-controlled cat lamp with an ESP32-C3 and LED filament. Grab the open source files and light up your home!
Cats are commonly found in the home labs of electronics hobbyists, where they do helpful things like chewing on the wires of circuits that work too well. But not everyone can have a cat, due to allergies, space restrictions, or for other reasons. GitHub user likeablob thinks that every home lab should have a cat, so likeablob created one that everyone can own: a cat-shaped ESPHome-controlled lamp.
The entire enclosure is 3D-printed, and aside from this casing, you will only need an ESP32-C3 Super Mini development board, and about 30 cm of flexible LED filament. Firmware for the microcontroller was built using ESPHome, which makes it a snap to integrate with your smart home. This makes it possible to use your phone, a smart speaker, or a computer to flip this little kitty light on and off.
The circuit diagram, 3D design files, and instructions are all available on GitHub under a permissive MIT license. Go grab them and get started on your own cat lamp, even if you already have a lab cat at home to assist you.
