Opposable Stick · beta firmware 0.1.0

Make your own Stick

The Stick lets your agent tap and type on an iPhone. It pairs with the phone as a Bluetooth keyboard and pointer, and your computer drives it over USB. We don't make the hardware: you buy a small ESP32-S3 stick from its maker for a few dollars and install our open firmware on it here.
