This is a soldering kit for building your own ammeter clock (i.e. showing time with ammeters).

  • The circuit is driven solely by various CMOS logic chips from the CD4000 series.
  • The board itself has a crystal driver for accurate timekeeping, however it does not have a backup battery.
  • Powered by a 5V adapter with reverse polarity protection. (Adapter not included.)
  • Adjustable trimmers for accurate current outputs.
  • Fully open-source.

The Ammeter Controller Kit Contains the PCB and all the parts for populating the board. Does not include the front panel, ammeters, power supply, or enclosure.

Aluminium Front Panel A white front panel made with aluminium PCB. The front panel is designed to fit three 85C1 analog ammeters and four 12mm push buttons. Made to be put on a 9.8"X 7.5" X 4.3" enclosure box. (More info in the manual.)

Enclosure Kit (2-4 weeks lead time) Additional enclosure parts in case you don't want to source them yourselves. Please note that most of the time it's going to be cheaper and faster if you buy these parts yourselves from AliExpress or Amazon, and these are not stocked. Expect 2-4 weeks of lead time while I source them for you. This kit includes:

  • 1x 9.8"X 7.5" X 4.3" enclosure box
  • 1x 85C1 analog ammeter (30mA)
  • 2x 85C1 analog ammeter (100mA)
  • 4x 12mm momentary push button and connector (with or without LED)
  • 1x 5.5x2.1mm Panel-Mounted DC jack
  • 1x 5V DC adapter
