Hey all, so im making a simple (or so I thought) electrostatic detector based off a mpf 102.
The schmatic looks like this. I got it from someone else, and there circuit is working great, they actually already built 3 with the same design, however mine doesnt work.
The Idea is the light and buzzer are off. And when the coil picks up a static charge, the light and buzzer will turn on.
However mine is reverse. As soon as you turn on the circuit. The light and buzzer are already going off. When you introduce a static field, the light and buzzer turn on.
Is there a reason mine is working in reverse to how it should and all the others.
I already ruled out environment as im testing mine right next to one wired the same way that works.
Thanks.
