Re: Screw the smartwatches...
Haha, that's lovely! To save you other guys having to read through the link, here's the gist:
Pluto is a programmable digital watch that re-uses case and LCD panel of the Casio® F-91W*. This is the hardware repo, for the software side of things, see pluto-fw. Looking for pictures? There you go.
Displays time in decimal/binary/hexadecimal base
Multiple countdown timers
Uses RTTTL ringtones for alarm sound
Generation of time-based one-time passwords according to RFC 6238 (WIP)
Infrared receiver for software updates and TOTP secret transfer (WIP)
Useless customisation (Key beep frequency, etc.)
approx. 1 year battery life (estimate based on current consumption)
* You know the one. It's the Casio 'Terrorist' watch, commonly seen on young folk near you. Its nickname came from the idea that if you were writing a time-bomb construction manual, you would choose a cheap, reliable, and easily available timepiece. Alas for the US authorities who started the story, possession of a F-91W is about as much use as a proxy for 'terrorist' as possessing a beard.
