My Hardware Projects

Bike Lights: LED lighting solution for my bicycle, built around ATTiny861a MCU. Features include two buck (step-down) converters with 2.5A and 450 mA outputs, one boost (step-up) converter up to 30 V and 450 mA, 7 to 12 V input power, ambient light sensor, two status LEDs, two buttons, optional brake lever sensor for brake light, etc.
Tinyboard: multi-purpose 2.5x5 cm board with 8-pin ATTiny (e.g. ATTiny13/25/45/85). Allows various pin and power configuration, including MOSFET-driven outputs and boost (step-up) voltage regulators for LED strings.
