I have a few of these beastly looking whatever they are I acquired from taking apart few copy machines and what not.
Just wondering what it does and how it operates. It has got 3 legs.
And what are them shiney clear glass like LED's. Are they plain LED's or there is more involved with them.

Don't know what that black EYE looking thing is but the clear LED's might be infra red. Or they could be just about any color. I have a bunch of red, yellow, green, blue and white. I even have several IR LED's. They are all clear.
