I stripped magnets from a hdd and the fan comes from a server. Stirrer bar was bought in germiston for 25 bucks and beaker was 30. All in under r100-
 
Does anyone know where I could get one of those stir bars in the Randburg area?
 
hehe cool stuff man, my arms are sore from shaking my bottles. They so sore I can't ummm....
 
Just a heads up. If anybody wants to order from Labequip, it`s best to email first and make sure they have what you need at the office. They keep majority of their stock off site.

Until I saw this thread I thought this was all my own idea and was going to post something new. Such is life... Some slight differences though. Works just fine using an old 5V, 2Amp cellphone battery charger as power supply.
Currently using parts from an XBox. Thanks to the above will be ordering a proper "Flea" soon and maybe upgrade to a 12V power supply if the flea can handle it.DSC_0291 (1).JPG DSC_0290 (1).JPG DSC_0289 (1).JPG DSC_0288 (1).JPG DSC_0287 (1).JPG DSC_0284.JPG
Currently using the magnet that "locks" the CD to the CD drive.

Built from recycled material. Cost so far = R0.00

Cheers.

I've always been too afraid to use an open piece of metal in my juice. Have you noticed it affecting the flavor at all?

Hi @Caveman , I also use a metal bar and no difference at all. I mixed 2 of exact same juice, one without stirring and one with stirring with the metal bar and no difference. (But I did clean it properly)
 
Anyone found one in Cape town yet?
 
Thanks for bumping this thread. This is surely something that I will make.
Thinking of using a laptop cooling pad. The benefit is that it comes with a table.
Now I need magnets, stir bar and a beaker.
Where can I find a dead harddrive ?? I have several back in india but shipping it from there would be a little too expensive. ;-)
