IR Input

I’ve built my modification of the Barton Infrared Input. It’s pretty much as I breadboarded it with a couple of trivial exceptions. One is that I wanted to change the direction of the gate sensitivity/threshold pot… but I managed only to mirror it along with its inputs in the schematic, so it came out the […]

Playing with fire

The Barton BMC78 Infrared Input is one of those modules that realistically you probably would not use much, but it’s fun enough to want to build it anyway. It’s just an infrared phototransistor, AC or DC coupled to a buffer, with a CV to gate function. Check out the demo. I built the circuit on […]
