Nixie Alarm Clock

7:50 pm Clocks

This is my first Nixie clock. It uses four multiplexed tubes and includes an alarm feature which wakes me up every morning.

There is no snooze function, and the alarm will continue to beep until I shut it off.

The microcontroller is a PIC, coded in assembly. It uses the PIC’s 32KHz oscillator to keep the time.
