Projects

Each one written up in full — how it works, the decisions behind it, and where it caught me out.

ESP Hub

A desk hub on an ESP32-S2: nine apps behind a wheel menu, driven by one rotary encoder and two buttons, drawn to a 128x64 OLED at a 60 fps frame budget.

ESP32 Shipped

FanCam

An ESP32-CAM that streams MJPEG to a browser while driving a 4-wire fan at the 25 kHz PWM spec, reading its tachometer on an interrupt, and catching a stalled rotor before it cooks.

Embedded Prototype

Matrix FIDO

A board port: driving a 64-pixel panel from pico-fido without ever blocking the CTAP path. The authenticator latches intent on core 0; a 60 Hz task on core 1 does the pushing.
