DIY Stirplate

[Barley-Davidson]

I just finished my homemade stirplate - the total cost was about $40. Could be done for less but I picked up most of the stuff at radio shack. Parts list at the end of this post.

First I threaded the power wire into the project box, tying it off so it stays put.

Next I added the power switch and speed control. You could skip the switch and just make it always on when plugged in.

Then I wired everything up.

The fan is attached to the bottom plate with bolts, nuts and washers. The fan can be adjusted lower if need be.

The magnets are mounted on a metal disc. Right now they're just stuck on, if I find them drifting around I'll glue them down.

There are lots of how-to's online for this project. I based mine on this one http://onebeer.net/sp_howto.shtml

Don't forget that old hard drives make a good source for rare earth magnets.

Very nice, barley! I"ve been planning on doing one myself soon.

Thanks.
I've got the soldering skills of a chimp and I was still able to slap it together while my son took a nap. It's a pretty easy build.

Great job. Now I just need to make one damn it.
