Chair mod

post #1 of 13
Thread Starter 
I came up with an idea this afternoon while i was messing around with an electromagnet connected to my stereo. I was holding it in my hand while listening to music and I was thinking it felt really cool to feel the music in my hand like that.

Then i though... what if i were to put this and more in my chair. I have one of those cloth netting chairs (really thin with little holes in the fabric) so I took the magnet and used a twist tie to attach it to the back of the chair.

Then I cut a piece of wood to run along the very back part of the chair and attached the electromagnet. So now I have the electromagnet about an inch from the back fabric of the chair (and the magnet).

So I sat down and picked out a song with some good bass (it responds much more to bass) and (surprisingly) it worked very on the first try.

I was thinking it would be cool to add more of the electromagnets all over the chair so its not just in one spot as well as adding more powerful ones.

As of now I'm using one amp to power my speakers and another to power the electromagnet because the volume needs to be up very high to power the electromagnet (i think because of the fact that the resistance of it is like 20ohms rather than like 8 for most speakers (i think ))

Pics to come...

Would be quite expensive in the long run to get amps to power all of them -- but cool nevertheless! Looking forward to pics my friend

Was it Modki? I think it is. He did a chair mod. It looks awesome.

Good luck on yours!

Well it's broken now actually : ) lol... it was only a prototype. I put the electromagnet on an aluminum base to radiate heat from it and i used some thermal paste and hot glue but the glue melted and it fell off.

As far as power I don't think it uses all that much. I'm thinking about as much as the speakers I've been using anyway. I have 2 amps laying around so I could power 4 easily. Too bad I don't have any more electromagnets.

I'll get some pics with a better version tomorrow.

Can't you just make an electromagnet with some metal pipe and thin wire?

Well, get a decently sized guitar amp/speaker combo, and jack it into whatever sound source you're using and attach the speaker section to your seat. It'll vibrate like crazy.

That's pretty simple actually, it's essentially an amp connected to a speaker with the woofer replaced with a weight. It'll shake like crazy.

So wait is sound going to come out of these or just vibrations? I like bass as much as the next guy but wouldn't this get kind of annoying?
