hot plate

Ah! It's brilliant! I shall use the case of the other plate warmer and go with this pentium idea, it should get plenty hot now. Although I will have to go buy another Pentium 1. Last time I saw my other one is when it fell out of the truck and got buried in the drive way. Oh well, guess I will have to go to the junk yard and spend .2 cents to get another one

Whilst I think it's a great idea; somehow I don't think you can draw enough power to heat a coffe mug from a USB port.

It's also a lie that heating coffe is the only think old Pentium CPUs are useful for; they have many applications in embedded products and routers.
