Simple Infra-Red Transmitter/reciever Shematics

Hosted circuit

This circuit is also Crossed to: , Infrared

This 1 channel infrared transmitter/receiver remote control is the cheapest and simplest you can find. The transmitter transmits a sequence of pulses on 36 KHz frequency carrier. The diodes are Schottky type because of their low voltage drop (only 0.2V). The ripple counter 74HC4060 contains an oscillator which controls the frequency carrier to be 36KHz.

The current consumption of the transmitter with the button pressed is 6mA. The receiver is really simple without any coding/decoding stages. Of course in

I,m design this IR transmitter,all elements are original by schematic diagram. I think that I can power-off or power-on any TV whit this el. device,but this not work? Where am I wrong!Can anybody ask me,please!

.,.how about i haven't BAT 85.,? please!

i'm confusing in ir..which ir can i use?

Note that IR emitter (LD271/LD274) is wrong way around. BAT85 is not a critical component; any small diode like 1N4148 will do.
