Full wave precision rectifier
This precise full-wave-rectifier is a circuit made to rectify those values that a normal bridge rectifier cannot rectify.The diminution of the diode bridge rectifier’s typical power is (obviously, it depends on the type of the diodes) of the 0,7 volts-an approximate value.
A Digital voltmeter
This circuit is composed of two integrated circuits. A digital analogue converter (CA3162) and a seven segment decoder (CA3161).
Voltmeter ammeter and wattmeter with pic
The project that we present here is a meter of volts, amps and watts, to which we have also incorporated a temperature sensor to activate a fan, or other mechanism that we want, through a relay.
128x64 display for Pc
This circuit allows us to connect a 128x64 display with the PC parallel port.
Automatic Pc power on
This circuit is used for switching a computer or any other device which start operating by a click, after a blackout (when power is restored).
Proximity sensor power on for Pc
This circuit is based on the infrared receiver IS471F. The running principle of the circuit is easy.The transmitter is an infrared LED that emits a modulated signal monitored by the 4-pin of the IS471F.
Fan regulator with potentiometer
This is a simple and a very useful circuit to slow down the PC fans and remove the noise.
