fetdet1 Ridiculously sensitive charge detectorHere’s a simple project that might be interesting to try out. This simple circuit can detect the invisible fields of voltage which surround all electrified objects. It acts as an electronic “electroscope.” Regular foil-leaf electroscopes deal with electrostatic potentials in the range of many hundreds or thousands of volts. This device can detect one volt. Its sensitivity is ridiculously high.
