'Tis the season to salvage junk! Where I live, poeple put out big piles of trash every year in April. It's amazing what one can find. Last year I must have found 15 or 20 speakers. I first found out about rare earth magnets from the Smash Lab episode ''High Rise Escape''. I soon learned that they could be found in old speakers. Alright, enough talking, go find some speakers!
Step 1: Open 'em Up.
Okay, now that you've found some some speakers (you have found some, haven't you?) get out a hatchet and knock in the back and then the sides. If you don't have a hatchet, you could use a hammer. If you don't have a hammer either, then what the heck are you here in the first place (I mean, who comes to a site about making things without a hammer!). It's a good idea to do this outside, as it makes rather a mess.
Step 2: Pry the Magnet Off.
This part's simple. Just hammer a crowbar in there and pry the thing off! Actully, you should wedge a flat head screwdriver in first and get a bit of a gap first.
Step 3: Do It Again!
Now that you've got one magnet, try for 20! I've been collecting for 2-3 years and I've got almost 40. My best one looks somthing like a a landmine, and weighs, oh, I don't know, 30, maybe 40 pounds.
What to do with all those magnets? Maybe you could sell them on Ebay, or start a speaker repair shop - it's up to you. Have fun with this.
Black Hole over and out
