TV Remote Jammer!

Step 4 How Does it Work?

This is a pretty simple concept. When you press a button on a remote crontrol for a TV, stereo or other IR device, it creates a series of pulses which the receiver in the target device; in this example, a TV, decodes into the corresponding function. This frequency is around 35-40kHz. To confuse the receiver, this jammer sends out a steady stream of binary code (1's an 0's) at the same frequency, but contains no information to decode. The receiver basically sits there and does not respond at all and the real information cannot get through to it as long as the jammer is on. Voila! You've 'jammed' your TV remote!

I think that the infrared transmission frequency standard is 38kHz.

Could you please provide a close up of the back and front of your circuit. Thank you!
