I made a new electrostatic polarity detector.
Sensitivity has been improved compared to the previous version.
The output from the FDS8958A was amplified using a transistor.
Another advantage is that the anode and cathode sensitivities are approximately the same.
The previous version had much higher anode sensitivity.
