where do you get the motor?

Awesome the way you used that connector to couple drill bit and motor shaft, very useful

a clockers must -- if your CPU gives thermal -- you just drill more holes to the PC case (shot up me stupid cat, muhahaa)

If you want to reduce chance of damaging your USB port, try the next configuration.


I mean add a Diode like people said on previous comments xD

I don't see any EMF or spike suppression circuitry, I'm not sure I would use the USB rail as a power source for this, motors throw out a heck of a back voltage.

BeachsideHank thanks for the reply!

isnt it allready on the motor?

I hope someone else can verify, but it looks like a simple disk capacitor to me.

i'm gonna check this next week. i'll let you know what it is!
