In which I destroy a perfectly good radio-controlled clock in order to build a radio-controlled clock.
I bought a cheap radio-controlled clock mechanism, with hour, minute and second hands. I was intrigued to figure out how to decode the MSF signal, broadcast on 60kHz from Anthorn, Cumbria. After poking around the innards a bit, I eventually found a solderable pad that tracked a digitised version of the signal, and then wrote Arduino code for an ATTINY1614 to decode it.
