Back in 2015 I wanted to build an clock based off segmented LED displays that showed the time in Swatch Internet Time (.beats) format -- the official time format of tilde.town.
A mere 7 years later, this is that clock.
It's written in pure C with no external libraries and only targets Raspberry Pi's running Linux, with the kernel-level I2C stack.
- Obtain a Raspberry Pi
- And an Adafruit 14-segment LED display (with I2C Backpack)
- Wire them like Adafruit suggests
- Add
dtparam=i2c_arm=onto/boot/config.txt make && ./beatclock
Enjoy.
(Thank you to Dave Madison who documented the protocol in an approachable way.)
