Title: Computer Components and Magnets
Post by: JonnyBoy on February 07, 2005, 03:24:23 pm
Hey everybody. I am planning on making a control panel with the computer components built in so I can plug the CP straight into a TV. I also planned on hacking a set of computer speakers with a 5.25" set of   Sony Xplod speakers. My worry is the speaker magnets may mess around with the computer components which will be in close proximity. Would a set of bucking magnets help me out? Will there even be any affects on the computer parts? What do you recommend I do?

Bucking magnets are great for putting speakers next to monitors- but I don't know if you can count of perfect cancellation of magnetic fields in all directions.  Which might be important if you're going to have your hard drive nearby. 

A little magnetism near a monitor = you need to degauss.
A little magnetism near a hard drive = you've lost your hard drive!!

Maybe you should put an audio line-out on your controller next to the video out, and use the tv speakers, or home stereo.  Or a headphone jack.  Or build your Xplods into separate enclosures, that you could plug into your controller, but set far away.

Or, try it out anyway, it might work fine! :P  I offer warnings and alternatives, but don't insist that I'm right.

Yeah, I probably should just go with the audio line out. Is there some sort of connector that I can get to plug straight from the onboard audio to say, an RCA jack on a TV?

Yup, it's about 2 bucks at Radio Shack for the adapter.  Plus, you'll need a set of RCA cables long enough to reach.  Just tell them you want a cable to go from your computer soundcard to your TV or home stereo, they should be able to help you out.  It'll look like a headphone plug on one end, and have RCA plugs on the other end.

You got that 1/2 right.  Hard drives are shielded, so you would need a *very* significant magnetic field to corrupt any data.

You could always use some good old fashioned lead paint... ;D

Peale, I guess it's a good thing I've got a disclaimer!   :o

Honestly, I always heard magnets would murder my drive- another urban legend debunked!

I've had computers next to LARGE magnets for many years.  This one is hooked into the TV and stereo.  The big speaker right next to it has a 15" sub in it.  No shielding.  Been there for almost two years.  No data loss.

i put two speakers within 6 inches of a hard drive in my first bartop...no issues

I used to be in radio- Bulk Erasers are fun!  Put metal things on 'em, push the button, and watch 'em dance!  We found out that if you put a paperclip up there, and just pop the button one time, the field would throw that sucker across the room.. we used to have distance competitions.
