Ticks randomly, but keeps “perfect” time.
A single AA battery will run it for 18 months-ish. Connect ‘clock’ terminals to a lavet stepper motor style clock movement.
NOTE: This version has incorrect crystal loading capacitance. It runs ~120 ppm fast. There is a more recent design that fixes this.
BOM:
- R1 - 10k
- R2 & R3 - 100R
- C1 - 10 µF
- C2 & C3 - 22 µF
- C4 - 0.1 µF
- D1 & D2 - BAT54A
- L1 - 47 µH
- IC1 - ATTiny45
- IC2 - NCP1402 3.3V
- Y1 - 32.768 kHz, 10 ppm

GPS serial and PPS for Raspberry Pi.
Takes an AdaFruit Ultimate GPS module and connects RX and TX to the GPIO serial pins (optionally - solder jumpers to disconnect them are on the board), the PPS output to GPIO 18, adds a CR1220 battery clip on the bottom for warm-start, a U.FL connector for an external GPS antenna and a FIX LED.
