Step 1: Get the parts
- 1 TV-B-Gone
- 1 IC-socket
- 1 optocoupler
- 12 IR-LEDs
- 1 9V battery
- 1 flashlight
- Soldering stuff (knife, soldering iron, wire, etc.)
Step 2: Modify TV-B-Gone
To be able to put the IR-LED into the socket you have to cut he pins and grid the boarder of the LED to fit through the hole in the case.
Step 3: Modify Flashlight
Put the IR-LEDs onto the board with 4 in a row. The ends of the rows are all connected to the lamp socket. (The pulses made by the TV-B-Gone are very short, so you can connect it without a resistance).
Step 4: Insert the optocoupler
One of the output pins is connected to the battery, the other is connected to the light socket. the Other pin of the socket is connected to the battery.
Don't forget to isolate the pins.
