THE *COOL* COOLING HAT
Ok I had an idea... Yesterday while I was taking processors off of motherboards.... I found a rather normal looking heat sink. and droped it on my hat. By now you have probably figured it out that I have a messy room and I want to make a cool(ing) hat. So I am thinking of running a little pump (very little) and fan off of 1-2 9v batteries. Some Kind of coolant (water) and a couple of prototypes And I will have a cooling hat....
(YES PEOPLE I REALIZE ITS WINTER!!! (where I live))
Any ideas ?
