Nice. It sure beats my usual method of throwing my headphones in a cluttered drawer of random stuff in my desk.
I imagine if you spin the disc fast enough, the files would fly out of the sides because of centrifugal force!On a more serious note though. I imagine it's possible to write something uniform across the whole disc. Imagine you write a 1 to every memory location on the disc. Not only would it render the information on the disc unreadable; it would also give the disc a uniform color - (I know for many CD's and DVD's the written area is darker than the unwritten area). There's a program called DBAN (Disc Boot and Nuke) that does something like this for hard drives, it might work for disc media.Going from your picture, your works look very nice. Good luck!
Nice product, now when we are at the DVD subject, I like to know if its possible to delete a allredy DVD/ CD or Blu-Ray write only disc, so I can keep the disc but delete the files, and it still looks like a new DVD? I collect discs and build lighting fixtures from them, but some time i get discs with files on that i dont want to be read again, thats why i like them in the same condition as new.

Try connecting a "dummy" coil to the disconnected output. Try to choose a coil of similar impedance to the yoke. (1-2mH, 5-10 ohms).Next time try using a small black and white unit. The simpler the better.
I've definitely experienced this flaw! Especially with a pair of nice low impedance headphones being plugged in at the same time as a pair of cheap ear buds. Luckily, my non-audiophile ears weren't sensitive to any introduced distortion, but the volume difference is huge. For high impedance loads (auxiliary ports and the like) I haven't had any issues.The resistor thing is interesting. I'll admit that I don't entirely understand passive audio circuits that work that way; I suppose the 33 Ohm resistor effectively swamps whatever impedance your headphones are, so the differences become negligible?
Unfortunately this project suffers from a basic flaw - the implementation means that any set of headphones can load the other set(s) and therefore introduce distortion to all sets. This is because different makes of headphones have different impedances which the output device (phone, amplifier, etc.) sees as a variable load and so ends up providing variable output power which one moment can be too much and the next not enough to drive the different headphones.Even the same make and model of headphones can have variations in their specifications - all specifications are nominal i.e. expected with a tolerance of +/-5% usually.Decades ago now (1987) I built a few variations on a splitter box based on circuits published in various audio magazines and audio textbooks - the best one had each socket loaded with a 33ohm resistor on each leg containing audio (i.e. the left and right channels for each socket but not the ground line for what is hoped are obvious reasons). All resistors were matched to within 0.5% (i.e. +/-0.165ohms) What this did was ensured that the load seen by the driving device (amplifier, phone, etc.) was constant at all points in the circuit; variations in the impedance of individual headsets became a non-event.

no problemactually I finally did it! and I find out what was the problemthank you very much for your help :) and your instructions.
Great design, would it not be better to use an Aluminium foil as the reflectivity ratio is probably better compared to the CD.
I used jerkey's suggestions and just rotated the coils and hooked the old horizontal coil to the speaker lines. This is intended for a brain-in-a-jar project so random wave patterns is just fine.
You should do fried eggs! that would be funny... your friend grabs them and then yolk is everywhere!
I got an old CRT monitor can I use for abovewhich wire is best to extend the coil wires out of the cabin like any suggesions to use a Monitor cable etc.Frequency limitations of this CRT oscilloscope
-1 for using "camouflage" instead of "hamouflage". Otherwise awesome. Will soy ham work, do you think, for us weird, commie vegetarians?
I used an auxillary cable that my teacher found me. it was old enough.
The headphones that I use have tons of tiny coloured wires within them, not the three wires described.
Hey, I really want to make this but all the headphones I've cut apart are too new! Could you let me know what kind of jack to buy? Thanks.
