Questions

What parts does the Ammeter clock use?

13 parts, built around the LM358 and IRLZ44N. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.

Where can I download the Ammeter clock KiCad files?

From the benhg/ammeter-clock repository on GitHub, at the commit this page was made from: the board is ammeter-clock/ammeter-clock.kicad_pcb and its schematic ammeter-clock/ammeter-clock.kicad_sch. PCBKit opens the board in the browser, with nothing to install.

Can I use the Ammeter clock design in my own project?

Its repository states no licence, so its author keeps all rights: ask benhg before reusing the design.
