With this hack you will be able leave the remote in a room and it will turn the TV on or off/change the channel every couple of minutes automatically.
Please note that this was produced n a college dormroom and was done with the few supplies I had. I am sure that there is a way to make this more compact but I did what I could.
Thinkgeek Micro Spy Remote
Thinkgeek conductive glue
555 timer chip
9-volt battery connector
High Gauge wire
Aluminium can (optional)
Tape (electrical tape works well)
needle nose pliers
wire cutters and strippers
possibly other common household tools.
Step 1: Deconstructing the remote
Use a knife to peel back the front covering of the remote. It is a flexible piece of plastic with an adhesive on the inside surface. There are also black dots of conductive material that makes a connection when the "buttons" are pushed.
Remove 6 Phillips head screws. Keep these in a safe location for later. Lift the circuit board out of the lower casing by carefully lifting the back side up first and then pulling out. The goal is to not damage the infared LEDs at the front of the circuit board.
Keep the sticking front plate from sticking to anything by keeping it in a safe place. Try to maintain the integrity of the adhesive to make it easy to reassemble later.
