Here’s a video of the CD machine in action. Playing/pausing of the CD is done using the normal buttons on the CD player.
Sorry about the player stopping suddenly at the end. That happened because I was making the one “dangerous connection” on the machine. When connecting the first and second pins on the bottom row, the CD player crashes. This can be easily fixed by turning the anti skip feature off, then back on, as shown:
It’s also a handy way to quickly get out of “ridiculous” sound mode quickly to start manipulating the sound from its normal state again.
And there you have it, the Sony Discbitch – a circuit bent CD player. I hope you all enjoy and have fun if you choose to build your own!
Until next time!
Additional screws added to keep the CD player in place better:
Now, at the moment, one could push play, but nothing will happen. This is because of a small button in the lower left of the CD player that prevents it from playing discs when the lid is open. It’s pretty tiny and my phone takes awful pictures, but here’s what it looks like (for what it’s worth)
Apply crazy glue to stick it down and… We’re finished!

Wait, what’s going on here?
It seems to me that there is something missing on this outer face of my box. What could it be?
PHOTOSHOP. (filename: bitch as in badass riot grrrl cd player machine not as in something derogatory also the person who writes this blog is a woman.png):
I want to put this on the outside of my box. Employing state of the art preschool technology, I printed the image out, traced it, scribbled pencil on one side of the paper, and went over it again with the paper taped to my box.
Hard to see the pencil outline, but it’s there.
Time to go over it with a soldering iron.
To get everything from the CD player working with the new patch bay, I soldered each pin from the RAM to a banana jack, and connected the two switches.
I then screwed the faceplate into the box I made and let the CD player rest on top.
The contraption is now finished!
Or is it?
For the faceplate of the CD machine, I used a piece of plastic. I cut some holes to mount the panel to the rest of the box, plus ten holes for banana jacks.
Banana jacks are a beautiful thing. These are what each pin of the CD player RAM will connect to. When the machine is finished, each jack will correspond to one of the RAM pins, and they will be connectable via patch cables. Banana cables/jacks are super awesome for making patch bays because the cables are able to stack, meaning you can cram multiple cables into each other to connect more than one thing to a given jack at a time. It’s great.
Anyway, I then drilled two more holes in the faceplate and used a square file to shape them into suitable rectangles for the CD player’s switches to sit in. I desoldered the switches from the CD player in order to measure them and put them in the faceplate properly.
Here’s what everything box-related looks like all together so far:
Now that everything is semi-done, I’d like to put my machine in a pretty box.
For less experienced boxmakers, I must stress the importance of CONSIDERING THE THICKNESS OF YOUR BOXMATERIAL. It may sound obvious, but real life boxes differ greatly from theoretical math class boxes because they’re made of actual physical stuff – determining your dimensions with your material in mind will keep your pretty box from becoming an ugly box.
Anyway, my plan for the CD player’s housing is something vaguely reminiscent of a frankenstein Moog effects unit. Wooden sides with a black faceplate and all that. Here’s a wood-like substance with my cuts outlined:
Here’s everything after cutting. I used a bandsaw because I have access to one, but one could use a less fancy tool depending on what is available. After all the pieces were cut, I did a big vertical cut in what will become the bottom of the box. This made a bit more space for the electronics and faceplate and all that.
Here are some little brackets I made myself out of sheet metal. The process consisted of cutting the little strips, drilling holes, and bending them into right angles with my bare hands like a boss.
Finally, I screwed everything together. It looks like this:
The bottom piece fits snugly inside the three outer sides and the cute little L brackets are bolted in place. Yay!
Solder a little wire to each RAM pin, and you end up with this
When a CD is playing and you connect these wires together, crazy stuff happens. I highly recommend grabbing some alligator clips and playing with your machine at this point. It’s loads of fun!
There are switches attached to two of the pins because I’m crappy at soldering. I accidentally broke the connections to two of the pins while attempting to solder to the tiny contacts, so I went ahead and chucked on/off switches for those pins in there while I was fixing them.
And that’s it! The electronic component of this project is now complete. You can all go home now. Next: putting it in a pretty box!
