This circuit is a basic function of the FET 2N3819, which acts as a switch. In the conduction and not conduction. It runs contrary to the transistor. The circuit can be used to delay the cycle is small. Such as delay, 9-volt light bulb, or motor delay to any DC 9 volts. When raising the [...]

This circuit, a simple mixer circuit.It can mix two signal channels and one channel is output.Using a codec circuit,Convert stereo audio to mono audio time. It can increase the number of channels too. By adding a VR1, R1 and C1 to the amount needed. Then connected to Buffett a new one.Most importantly is eating circuit [...]

This be Very Simple Touch Switch Circuit. It used UJT 2N3819 is Main part numbers should set up this outside building circuit. When stay far from electric line or Power Line very much. Enough touch at infront touch 1 metal and 2 make Relay work ON get. When but urgent touch 2 metals only make [...]
