This an electrostatic field detector (a.k.a. as "V-Scope") that uses a common antenna to repond to ambient electrical fields. The LED glows brightly when positive charge approaches and becomes dimmer or blinks when negative charge comes in contact. | This an electrostatic field detector (a.k.a. as "V-Scope") that uses a common antenna to repond to ambient electrical fields.
