I have few FET but It will work of not I don't know. I have BS170 FET. I found another FET "596s" inside of electret mic. Other FET can't find. Will these two FET able to detect Static cherge like shown in schematic (FET version)?
Another is Transistor verson Detector. Is it sensitive? I want to use 557 as a PNP and another general purposes as a NPN (like 547), is it valid?
Do you have any other simpler ans sensitive?
I hope detector will detect charge without touching its probe (Ant), almost far from few cm.
