So I just finished disassembling this garbage Epiphone amplifier I had sitting around (it came with my starter guitar). There's lots of good electronics parts (pots, capacitors, a few big transistors, resistors, other -istors, etc.) and I know at least a couple of these will be helpful in the near future (one of the pots will act as a fan control for my Zippy PSU's jet engine, I mean fan). But what to do with the speaker?
I've already used the magnet (still inside the speaker) to lift up a few difficult washers. The speaker had terrible sound quality so it's no use as what it was made for. So is there anything neat you can do with a speaker magnet?

How big is the speaker?
There's plenty of things to do with a speaker.

Most of the time those amps are good for modding / circuit bending (http://www.google.com/url?sa=t&source=web&ct=res&cd=1&ved=0CBwQFjAA&url=http%3A%2F%2Fen.wikipedia.org%2Fwiki%2FCircuit_bending&rct=j&q=circuit+bending&ei=aU_vS93nO8WclgeL_Ni0CA&usg=AFQjCNEn_7apE0B1PhSlPOj5EFmPXpSNEg) if you're a guitar player or electronic musician of any kind.

Not everyone's cup of tea, but the aesthetic is not too far out of line from geekhackers :P

Hmmmm, I'm going to try that with my Fender right now. :D

I have a feeling the eyeball mod looks better than it sounds.
You can rip the cone off and use the coil as a resistive load for sound dampening (http://www.tedweber.com/atten.htm). My Allen Amp just rips the neighborhood even at 35 tube watts.
Would this be the same concept as a Marshall Power Brake? I'd love to get natural tube distortion from my Fender Hot Rod DeVille 4x10 at a lower volume, but I haven't found a solution I'm comfortable with... playing with speaker loads intimidates and worries me.

I've decided not to mess with my amp, I just got it a couple months ago. For the record, it's a Fender Vibrochamp XD. Best amp I could afford at the time, and more than I could afford now. :p
Anyway, the magnet is apparently permanently bonded to a metal housing, and the housing is welded to the aluminum speaker frame. I tried to remove the fabric and coil and such, but either I'm too clumsy or it's too cheap because that stuff tore like tissue paper.
Know of a way to remove a magnet from a housing like that? I'll post pics tomorrow, need to get more AAs.

If you have a terminal or RS/6000, then sure.

Okay... there must be some of those in the netherlands webwit could pick up and try the keyboard on.

Platters make awesome coasters, even for my 1 Pint coffee cup. Magnets are way strong. Ripster obviously has Arty type uses for the Head mechanism. An Empty HD shell is just great for confusing the living hell out of drunk techhie mates when you tell them you have a HD problem you can't fix ;-)

I've seen hard drive platters being turned into speakers on more than one occasion. They have absolutely no bass, but it's pretty awesome to watch.

Wow, never heard of hard drive speakers before, very cool!
Found this (http://www.youtube.com/watch?v=ZMmiqS8gKu8) when I was looking around, his keyboard has to be coated with some pretty nasty crap when he was done.

Actually the head mechanism is what (usually) makes the noise.
