Trumeter APM-FREQ Decorative Mains Frequency Meter

Erstellt: 2021-11-21 / GeƤndert: 2021-11-21 / REV 01

Brightness sensor for switching the decorative mains frequency meter on or off (depending on my presence at home). Just for fun project.

The Trumeter APM front panel instruments are an interesting piece of (niche) equipment.
