my first intractable so give suggestions :)
ummm... not liable for shorted out usb ports, broken computers, flying fan blades of doom or anything else people can get sued for :)
overall... don't blow your self up.
Step 1: Supplies
tiny motor (I used a zip zap truck motor yellow one)
nail gun nails (or some flat conductor)
plastic or something flat and NOT a conductor (thats cuttable)
soldering iron - solder
hot glue (super glue works better but is a pain to deal with)
usb port thing
some kind of knife (to cut the plastic)
Step 2: Cut Plastic
I used a flash drive to get the right shape
Step 3: Nails
cut the nails down to size
Step 4: Glue Glue Glue
(optional) glue the switch to the side of the motor.
note you probably shouldn't have the outside metal of the motor hitting the nails.
Step 5: Solder Stuff
solder the+ of the motor to the right set of nails
(if you are using a switch put the +end of the motor to one side of the switch and the right set of nails to the other side of the switch)
