if you've decided you want one, jump at that price, cos that's well below wholesale price. though there's a good reason they sell so much slower than the cdj's....

I first overclocked a CD player about 1 year ago, at my first position as an electronics repair technician. I simply used a coil and a capacitor as the 'tank' circuit, hooked up to the clock pin on the CD player. This worked pretty well, but you had to move a ferrite core into and out of a coil to change the pitch on the CD player. This obviously wasn't the best solution.
I went out and bought a couple of CD players from my local second hand shop, and started mucking around with them. I took the cover off, shorted out the switch that detects when the cover is open, then pulled out the 16 MHz crystal. I then fed a variable clock frequency into the CD player, and bingo! the CD player was pitch controlled.
My first couple of circuits were just a really simple Resistor-Capacitor oscillator, but that had the problem of changing pitch when you put your hand near the slider! Sort of like theremin, but not really all that good for matching beats.
I then started to try to make a voltage controlled oscillator, and came up with the pitchman circuit. This has gone through a couple of different versions, and although the current version is pretty good it could probably be improved apon a bit more.

Here I am, slowing down the spinning CD player with my finger. This actually works, and you can hear the pitch bend down, |
