This is an open-source KiCAD 5 design files for a logic chips-driven clock that output time on three ammeters.
This is a unique clock that will certainly impress people around you.
- Ammeter Output
- Shows hour, minute, and second on three ammeters.
- Works with both analog and digital meters.
- Quartz Crystal-driven Clock with CD4060 IC
- Design with logic ICs. Only need 11 chips for the circuit to work.
- Set Hour, Set Min, Reset, and Clock Halt buttons
- Ammeter adjustment trimpots
- Aluminum Front Panel design available here
We are currently at Revision 2. Changelog is below:
Revision 1 (July 2021)
