infra red transmitter and receiver

[anmolt]

anyone know a simple circuit for these ..........basically need the receiver to act as a switch so that it can turn on the mosefet as it receives the IR ........

What's the IR input? If any input would work you have cap that charges off the IR output put that to your FET, then every time there is IR signal the cap charges up and turns the FET on. Cap holds the FET on for X time. Also need a resistor to ground to slowly discharge it as well.

MosFET IR switches - fffppppp!
I hope I never see the day when I'm that damned lazy that I can't raise the effort to tell the wife to get up and switch the bloody MosFET.

I'm sorry...what.....I've done that one before........? Oh......
