This hidden device can intercept remote control signals and play them back!

This fun project lets you take control away from the person holding the remote control by intercepting the invisible signals as they travel through the air so you can play them back to the TV or video machine. You can also “train” your Remote Hijacker by recording certain button presses directly from the remote so that you can play them back later on, taking total control over the target appliance. Because this project records the remote control pulse stream directly, it will work on any infrared based remote control, able to learn a few button presses.

This project uses a very simple microcontroller program that just times the pulses coming into the infrared decoder and then stores them in the internal SRAM for later playback. The source code is made as simple as possible, allowing for plenty of room for modifications and alterations to suit your evil genius agenda. Because no interrupts are used, the C program could be ported to just about any microcontroller, and will work on all of the Atmel microcontrollers as is. Larger internal memory allows more button presses to be stored, with the Amtega88 (1K SRAM) allowing about three button presses to be recorded and played back.
