I was going through an old project notebook, and ran into the following entry:
“I’ve been trying to figure out how to build avoltage attenuator for a couple of years, and my current brain exercise is to make a circuit that will pop a servo motor to 180° until a touchswitch is hit, then pop it back to 0° and shut off.
sigh. I’ll get it.”
(I have a feeling this was some kind of automated scope lens cap, so I could do darks/flats remotely)
I wish I had better notes for this project…
