    Hi Everyone:

    I am looking for small optical sensors for a coffee table I will be building. Any ideas? I mean small!!!!

    I have found small infrared detectors in VCRs that I have dismantled.
    I've used them to operate crossing gates and flashers. Most are about 1/8"square, I've seen them as small as 1/16".
    Would something like that work?

    Thanks All:

    I have taken senors out of VCR's. I have even built the contol cuircits for it. It's a pain in the a@# to fine tune! I replaced them with Banner Optical senors, but they are too large for the coffee table!

    I have check out the links, thanks guys! I have bookmark them all.

    Happy Holiday's,
