You can buy inferred LEDs at any RadioShack for less that two dollars each and you wont need more than eight. A cheap webcam can be as inexpensive as $16.00. Literally all you have to do is connect the LEDs together and power them up with a 9 volt battery. You should put a 5 ohm resistor in series with them just to be safe and you should never power just one LED off of the battery alone or it will burn out. LEDs are designed to run on minimal electricity in the first place. Once you have your LEDs connected together just plug the webcam into a computer and turn out the lights. You should now be able to see the LEDs lit up when you look through the webcam.
