My DH is a computer geek. His office? Packed to the rafters with old systems, parts and all sorts of 'crap'. (I call it crap, he calls it stuff.) Anyway, he derives great pleasure from disassembling harddrives that have died. He like the magnets. Upon my request he delivered a stack of platters and rings to me because I just KNEW there had to be a crafty use for them.
So I took a couple platters, a seperater ring, some pipe, some cut crystal chandelier prisms and some beadalon and made some windchimes out of them. They sound amazing. I think it's because the clapper (small platter) is also made of metal, so the tone is really resonant and rich.
The crystals fill my porch with millions of tiny, spinning rainbows and if I open my blinds my livingroom gets its fair share too. The super cool thing is that the platters are highly reflective so they reflect the rainbows too. I love these and they weren't hard to make or expensive. The hardest part was drilling the holes in the platters. Those things are TOUGH.
Hopefully the super extra special crimping job I did and the fact that I used beadalon wire instead of string will mean that these will hold up for a good long while. I can't tell you how many windchimes I've bought that've fallen apart in less than a year due to cheap string rotting away.
