Buddies,

Do any of you have any design advise/circuit for building a simple barcode scanner? I understand that there are a few ways of actually sensing the barcode 1.) using infrared bean 2.) using a CCD image capture 3.)using a laser diode and what not!

I am very keen on the sensing part, upon getting the info I can process it with any MCU, btw sometimes back there was this CueCat who everyone seemed to disect, however no one has any info on the sensing side, even that might help :)

Cheers
Linux
