well, if you're already acustomed to lightscribe disks, look at the inside of the disk. You'll see markings that are perfect for an encoder, you just need to find (mouse?) 2 optos to work with that. The markings are pretty visible in this picture I took: http://dsplabs.cs.utt.ro/~juve/dropbox/lightscribe/IMG_9645.JPG Regards, Alex ------------------------------------------------------------------------- Take Surveys.
