Read more here: Inside a TV Remote Control

"So the basic operation of the remote goes like this: You press a button. When you do that you complete a specific connection. The chip senses that connection and knows what button you pressed. It produces a morse-code-line signal specific to that button. The transistors amplify the signal and send them to the LED, which translates the signal into infrared light. The sensor in the TV can see the infrared light and "seeing" the signal reacts appropriately."

Thanks fuse...thats just what i was trying to find too!

I've not tried it out personally but I've heard that if you point a remote at a VCR camera you may be able to see the LED flashing on playback.

the CCD sensor has a wider sprectrum sensitivity than our eyes and can pick up the the Near IR signal.

Anyone know where I can find robotics parts ?

Found one at wwww.roboworld.com.sg but I want more sources.

Thanks !

Depending on your budget try these sites for a start
www.robotstore.com which is a professianal hobbyist store
www.budgetrobotics.com
same but cheaper

Try also
www.sciplus.com/categorySpecial.cfm

I'll be honest You actually gave us the "Key words" to find these
So here is the rest of the results ...I think you'll find something suitable here
