Started from Blu-Ray players now we here. Please take a minute to stop on by, share, or even pledge --- if not for a full Beefy ($750) or LadyBug Classic ($250), for a mini Blu-Ray-hack kit ($25), which will let you do all sorts of optics and little motors projects using the components of a single Blu-Ray optical sled.
