So how does it play them ? You hacked an actual CD player or you made it from a CD drive ? If you hacked a CD drive, you could help me, because I'm working on a CD changer as well, and I am most interested in making it out of an old CD drive.
I hacked the CD player. I put opto couplers across the switches so I could simulate a press and I took a signal from the motor to know when the disc had finished.
@nophead I see, so no IDE hacking, that's what I wanna do. Seems possible and I had been confirmed so, but I can't find anything useful yet, like where to plug the board or what code to write :(
@cristian3131, No not for that project but I have written IDE drivers for CDROMs at work. IDE is 16 bit parallel port. You send ATAPI command packets to talk to a CDROM.
Dude this great! I built something like this for old 5 1/4 floppies before the days of hard drives! I love it!! Brings back memories!!! Keep up the good work!
I have always dreamed to build jukeboxes but I havn't the necessary knowledge and specialized tools. I have a preference for vinyl (45 RPM) type jukeboxes than CD's ones. Now, with the PC multiple possibilities, I have discovered a particular one: the PDF Jukebox System (PDFJS) made on PDF multimedia format (a musical PDF document) with Adobe's audio-video embedding technology. I work also on Lamentia's WINCAB/DOSCAB projects for more real as a jukebox!
The video was made while I was dismantling it so there won't be any more I'm afraid. I can tell you the worst case delay was when it had to play the bottom CD from the top left corner. It would have to move 9 to adjacent pegs and then carry the bottom one to the player. I think about 1 minute in total. As long as the playlist had more that one entry then it would get the next disc ready close to the player so the changeover from one disc to the next was only about 10 seconds.
wow, that's pretty damn cool, i'm going to start on an mp3 jukebox soon, i'm starting with an early 70s fisher amp that i bought at a garage sale for $2
Reminds me of the robot that came with Nintendo. He could pick and place disks around his perimeter at target locations just like that.
Very nice! :)

Wow! this would be great for Towers of Hanoi puzzles. Nice work!

I cant believe you dismantle it. Did you redesign it to make it work better?

@nophead Can you teach me to do that PLS ? I have an Arduino board so that's what I wanna tap into if possible. Again, I have been told so :D

The vertical axis was reclaimed from another project, I made the rest from scratch, more details at the url mentioned in the description.

sure it can flip cds around but it would be good to show how quick it can go from the time you select a cd to the time it loads and starts playing.
