Do It Yourself CD Changer

SuperDuG writes "This is a true homebrew solution to saving a few bucks when it comes to cd changers. And to make it even better the whole setup is controlled by none other than linux. Seems like a nice setup to do batch burns without user interaction. Source is provided if you wanted to build your own." Not sure if this is very practical, or even if it would be cheaper than buying a changer, but it sure looks cool.

Kenwood's been useless, too. Not that I'm bitter or anything. :)

      As far as how the things actually work, no, they use different control signals. Most do put the line-level audio on 3 wires back to the head unit, but they vary on how they detect the presence of a changer and control said changer. It's a good idea, though, and I'd really like to know if anyone ever documents how any of them work. It just *can't* be much more than can be done with a serial port...

    I was thinking of doing the same by making a MiniDisc megachanger. Instead, for now, I bought a Sony CD-Audio megachanger and it worked out of the box. I still intend to go back to that idea though.

    One thing I wish would be done is better control of the Sony CD changer. There are S-link projects out there but all use the parallel port, and IMO, that's too hacktastic, I'd want to continue or build a serial port S-link controller. There is some _very_ slick control software that can even ID all the discs and tracks in the changer, and you select a track on a computer and the changer will play your music. Most people would do MP3 instead, but man-machine and electrical-mechanical interfacing is cool.

    Unfortunately, there aren't any Sonys that can burn discs, at least none that I know, and none that I know that can be used as a CD-ROM changer, at least affordably, so this project still has some merit.

  21. Usefull for a small inde band. by chrestomanci · · Score: 4, Interesting

    A friend of mine used to be in an unsigned Metal band. He told me that one of the most boring parts is copying CDs. Apparently commercial CD copy companies usually had a minimum order that was quite large, and always invented problems with whatever was sent to them, creating longer turn around and more hassle. The cost per CD was also quite high compared with burning their own on a CDR.

    Instead, what he would do, is to setup his PC next to a sofa in front of the TV, and manually swap CDs, while watching TV. He said that if he managed 20 CDs per hour (on his 40x burner) he would be doing well, but tropically managed less than that.

    It was of course, boring, and prone to error.

    A contraption to automatically load, burn and unload CDs, like in the article, would have been much better. He could have loaded it up with 200 blanks, gone to bed and come back in the morning to find it jammed, but at least with ~100 CDs done :-)

      Do a Google search for CD Duplicator.

      You can get a brand-new autoloading CD Duplicator (either attached to your PC or standalone) for $1500. It will also print and attach the labels.

      You can probably find something used on eBay.

      It seems to me that $1500 - $2000 is a worthwhile investment if it 1) avoids pissed off fans whose CDs won't play because of errors caused doing this by hand, 2) saves hours wasted in front of a PC, and 3) gives a pro-quality image to the band.

    This is definitely cool. For all the people saying this type of hack is irrelevant because of the storage difference between HDs and CDs, I must say that's rather short-sited when you consider that the form factor for optical media is most likely going to stay the same all the way into the violet laser media. So, while you could call this an out-of-date CD changer, you could also call it a cutting edge Blu-Ray changer. And commercial alternatives are insanely overpriced.
    But this is certainly not the last word on the matter. I've got my own plans as well. One thing we didn't see was any kind of performance specs about how big of an unattended stack the thing could handle. I read the part where he said it was just for fun, but I'd still like to know how many he could do consecutively.
    The option I'm considering is where you take a plastic housed stack of a hundred hundred discs sitting on a conveyer whith a slot at the bottom of the stack only big enough for one disc at a time to be rolled out. I think some of the commercaial solutions might work like this.
