Adding a motor to a USB Memory Stick
I've got this idea for adding a small motor to a USB thumb drive, for decorative purposes, but I have some concerns. I'm considering adding a very small motor such as this one: secure.precisionmicrodrives.com/product_info.php but I'm weary about the effects of having a motor drawing from the same power as the memory stick. Might this cause problems during read/write sessions? Also, I'm not the most electrically savvy person, so I just wanted a second opinion on whether the 5V from the USB (and 100mA?) should be enough to run the motor. (In my case, torque and speed are not huge issues)
I've also noticed that the motor is listed as requiring 3V, and I'm sure since this is such a small and delicate motor, it would probably be damaged by the 5V supply. Could anybody help me with the circuit elements that would allow for safely operating the motor?
