Wireless voltage detector circuit
This is one extremely simple wireless voltage detector circuit.
Although it is probably not very smart to use it as voltage probe it can still be used to detect high voltage presence in wires and also as a touch operated switch. The LED can be replaced with a relay to turn on and off some device (but only while there is something to detect). The circuit is very simple and it consists of only 3 transistors, 3 resistors, 1 LED and a 9V battery. This is actually a high gain Darlington transistor and the probe is a small piece of copper or a wire that will detect almost anything.
Check out the video after the break.

Uopste ne radi kako treba . Vise detektuje dodir, nego napon .
