Martian Mars Time Clock Kit
Build your very own Coordinated Mars Time (CMT) binary clock! This clock is designed to keep Coordinated Mars Time, which runs about 2.7% slower than Earth time. Wikipedia has a good article which explains Mars timekeeping: https://en.wikipedia.org/wiki/Timekeeping_on_Mars
This clock looks cool on an desk or table and makes a great conversation piece. Can be powered by a USB connection from a computer, USB hub or even a USB charger! The time is set with a simple on-board touch sensor.
Once built, you may set the time on the clock using this tool: http://jtauber.github.io/mars-clock/
