Device0058

Built as a set of two, this is a classic stepped tone generator originally designed by Forest Mims, also known as the Atari Punk Console. Built inside an old surplus plastic enclosure.

You have controls for frequency and pulse length, as well as a toggle on/off, and a led power indicator.

For demo check out Device0021, which has the same circuit.
