New project · Reference v1.1
A tiny XIAO ESP32C3-powered police car with flashing lights, a two-tone siren, MPU6050 tilt calibration, battery monitoring, and a Home Assistant dashboard with personality.
These projects are designed around daily use instead of one-time demos.
Each project starts with a real household or field problem and grows from actual use.
Critical functions stay close to the hardware and do not rely on a cloud service just to keep working.
Features, fixes, visuals, and lessons learned are kept with the project as it develops.
