I make small ESP32 devices and the software that talks to them. Printer monitors, clocks, a label printer that runs in the browser, a lamp you turn on by touching it.
Everything here started because I wanted the thing on my own desk. Some of it flashes straight from the browser, some of it you build by hand. All of it is open source.

SmallOLED
208GitHub starsA little OLED on the desk. Live CPU, GPU, RAM and network from a Windows or Linux companion, and an animated clock the rest of the time. Plenty of people run it only as the clock. Four panel sizes, a printed case for each.

DFPlayerDoorBell
A doorbell that plays whatever MP3 is on the card, wired into Home Assistant through ESPHome. Unglamorous, and still ringing at my door every day.
LedLamp
An LED lamp switched by a capacitive pad instead of a button. An Arduino Pro Mini and a TTP223, and nothing on the board doing more than it has to.
