Digital clock with pic 16F84A.
Single channel power amplifier with excellent audio quality. Applications in portable radios, tv sets, cassette recorders, interphones, and wireless tranceivers.
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.
Twilight switch with 12F629 microcontroller .
With a simple circuit and a microcontroller pic, 16F873A model, we designed this digital voltmeter in addition to any power source.
Pictures of some of the published electronics assemblies.
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.
This circuit allows us to connect a 128x64 display with the PC parallel port.
100W amplifier STK4044XI. rn
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.
That simple power supply is based on the usual 12 volts 7812 voltage regulator.
To assemble a computer part by part is actually simpler than it looks like. You only have to follow basic rules.
