Category: Inside Circuits Views: 5614 Rank: 10 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 Datasheet file1: Click here to download BAT85.pdf datasheet.

Related circuits The FM oscillator/modulator is a voltage-control led oscillator, which exhibits a nearly linear output frequency versus input voltage characteristic for a wide deviation. It provides a good FM source with a few inexpensive external parts This decoder features a sine wave recovery channel and uses a PIN diode attenuator driven by the sine wave recovery system to cancel out the sine wave sync suppression signal. This astable will trigger itself and run free as a multivibrator. The external capacitor charges through RA and RB and discharges through R8 only. Thus, the duty cycle is set by the ratio of these two resistors, and the capacitor charges and discharges between 1/3 Vs and 2/3 Vs. The circuit consists of the launch timer itself and an automatic-off timer. When power is applied to that IC, the countdown LED's sequence is on until they are all lit. When the last one LED1, is fully lit, transistor Ql saturates, energizing RY2. When that happens, a circuit between the lantern... is capable of flashing a large lamp. Flashing rate is determined by the 10-KO resistor and the 50-mF capacitor. Voice Activated Switch And Amplifier Circuit In certain applications, such as transmitter or other communications and control applications, this circuit should be useful. Both audio output and dc control outputs are provided. Voltage-To-Frequency Converter I Using a Burr-Brown VFC 32 IC, this voltage-to-frequency converter uses few components. The circuit values This circuit has a frequency range of 0 MHz to 2 MHz. Frequency can be adjusted to a precise value with trimmer capacitor C2

thx alooot for the nice schematic

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.
