How I build
- 01
Idea & research
Start from a problem or a part I want to push. Datasheets, breadboards and a lot of reading.
- 02
Schematic & PCB
Schematics, power design and routing in KiCad. Boards get made, then assembled by hand.
- 03
Firmware
ESP32 firmware written from scratch: wireless, low-power sleep and a UI that feels finished.
- 04
Enclosure & test
Custom enclosures that actually fit, then real-world battery and range testing before it ships.
