Any schematics or further info on the Precision Clock V2?

It's an awesome project and I'd love to make one for myself.

No schematics yet but I put the source code to the ATtiny up here. At least one person has built a replica of it using an Arduino which might be easier but I don't know if they ever got the centiseconds working properly. It's quite tricky to get it to tick perfectly in time with the once-per-second pulse coming from the GPS module.

The clock is still working great today, I particularly enjoyed watching the leap second happen at new year's eve (it handled it perfectly).

Yea, I used some existing libraries, and put it on an ATmega328p with the Arduino bootloader. Can find the code if you want it.
