Sensorwatch is a Casio f91w hardware mod by Joey Castillo.
Movement
The sensorwatch runs the open source "movement" firmware. There are several different flavors of preconfigured firmware available, but it's also quite easy to compile your own. That's what I've done so that I can select the exact modes I want to use in the order I want to use them in.
Flashing the new firmware requires taking apart the watch, but then is as easy as plugging it in with a micro usb cable and copying over your compiled uf2 file.
Currently, these are the modes I have on my watch:
- simple_clock_face
- world_clock2_face
- countdown_face
- stopwatch_face
- sunrise_sunset_face
- preferences_face
- set_time_face
- thermistor_readout_face
- voltage_face
