Home-Made speaker Test 1 !

Scris de sjackm pe mai 20, 2009

Hey all, I found a cool method to build a speaker ! Just search after “kipkay” on youtube, you’ll surely find it :P

And it’s quite cool too. This is what I did :

  • Made a coil on some scrap paper
  • Glued the coil on the plastic plate
  • Built some suspensions from scrap paper which will sustain the plate and coil
  • Put some magnets in the center of this coil while allowing it to move freely vertically

The result wasn’t as I was expecting, and I immediatly noticed the problem : the coil has a low resistance , meaning that it lacks of wire.

Well, anyway it had sound and also at full bass the plate was moving up and down, cool :D . At some point the coil began smoking. Here are some pictures and a video(smoking) with it :

Motor dintr-o bucata de sarma si magnet

Scris de sjackm pe martie 6, 2009

Am incercat sa fac un motor dintr-o bucata de sarma, magnet , curent electric desigur si niste agrafe de birou. E cam fail, dar macar am reusit sa-l fac sa se invarta.

Dupa ce fac rost de un magnet cilindric incerc sa fac un motoras calumea ( e doar pentru amuzament, am eu destule motorase acasa :P ). O sa ma mai documentez . Chestia asta functioneaza prin inductie magnetica ? ( de aia o sa ma documentez :P )
