Anyone else have an idea how to make one.
The idea i came up with was using a copper plate as a base, attaching a magnet at the bottom of the copper plate, then heating aluminum up to it's melting point and putting it on the copper plate, reason being because aluminum shows magnetic traits when in liquid form. then once it was all cooled off again drill some holes in appropriate places and mount to a chip. At least just to try it see how well it works.
