This echo machine has a 220V AC motor, not a DC motor.
What I think I might do is something like an AC light dimmer
triac thing. Like this:
The goal is to slow it down so that I can get longer delay times.
The 75, 150, 225, 300ms delay times doubled would be just awesome.
Hope this isn't OT. Thanks in advance for any input.
