Things people build on an ESP32
A curated list of real ESP32 builds - mostly ESP32-S3 boards with a screen on them: clocks, dashboards, sensor readouts, badges, tiny synths. Every entry links to a public repo, so you can build it yourself.
These have been flying around X lately, not least since Steve Ruiz's post. A lot of them run on the Waveshare ESP32-S3 Touch AMOLED 1.8″ - a good place to start, but any ESP32 belongs here.
