Infrared transmitters using LM3909

Infrared transmitters using LM3909
This is an infrared transmitter circuit of the signal is small and using a power supply of 1.5 V only. by the main electronics are the two LM3909 (oscillator IC LED Flasher) Normally, we tend to put it to work as a simple flashing light circuit. Use a source of low-power 1.5 V, which is working now easier to use transistors. The high frequency is very simple, just change the high frequency device only. C1 and R1 is less than the highest frequency.

TV Remote Jammer Using 555 IC

TV Remote Jammer Using 555 ICTV Remote Jammer Using 555 IC

The TV remote control transmits television signals as pulses of frequency around 37.5kHz. Each button on the remote control is pressed or equivalent has a pulse signal codes. This remote transmits pulses of the circuit block of the same frequency as the remote to your TV confuse decoding the transmitted signal.

The heart of the circuit is the 555 timer IC in astable circuit works mode.The output series of pulses at a frequency of 18 kHz to 48 kHz by simply adjusting the 5K potentiometer. What you do is adjust the potentiometer until frequeny jives to its distance from the TV or until the signal is ignored by television.
