A Nixie Clock in A
The incredibly compact IN-14 based nixie clock in a Marine Band
harmonica case. It shares the same code as my previous clock,
The circuit is mostly the same, except that it's changed for
IN-14's and made to fit in the tight space of harmonica case.
Eagle stuff is here.
Source code: Harmoshnik updates follow the Satashnik tag. This time I've had a chip that needed some serious calibration for its RC oscillator, the code update is mostly about that.
