  • 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).

  • We present you a retro assembly. This circuit was absolutely necessary years ago for us to listen to our vinyl discs. We all know what a preamplifier is, but what about R.I.A.A? R.I.A.A is a “Recording Industry Association of America”.

  • Single channel power amplifier with excellent audio quality. Applications in portable radios, tv sets, cassette recorders, interphones, and wireless tranceivers.

  • Twilight switch with 12F629 microcontroller .

  • This led clock circuit is quite complicated to assembly, because of the great quantity of connections it has, but the result is quite visible. 

  • That power supply may be configured, because depending on our voltage regulator, we’ll get more and less current at its output.

  • 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 is made to protect the speakers from the "pump" inconvenience, that is produced in some amplifiers while they are on.

  • The LM4861 is a bridge-cennected audio power amplifier capable of delivering 1.1W continuous average power to an 8 ohm load with 1% THD+N using a 5V power supply.

  • On-off push button with a 12F675 microcontroller.

  • This clock is for nostalgic people from “another electronic age” (without microprocessors). It’s a digital “old fashioned” clock and it’s already seen too many winters. 

  • With the familiar LM338K voltage regulator and a high-powered transistor, the 2N6031, we have set up a powerful 10-amp variable power supply.
