USB Fan question
This is more of an electrical question, but i don't know where to put this...here it goes:
I'm thinking of making a laptop cooler, using the USB port as the source. What's the maximum current I can draw safely from one port?

kay, here's what i came up with...i cheaped out on materials, but at least it's not very noticeable in class...besides the slight fan noise.
I'd like to be able to swap out fans with different connectors, hence the mass of wires. Could be a lot simpler.
Because of the height of the fan grill, i had to raise the laptop a bit.
I don't feel much airflow, probably because of the low clearance between the laptop and the fan.
