EDIT: The USB drive will still work and hold memory after you are done. There is no reason to cut of the circuit board; it would be almost impossible to do that with the USB drive you will need for this project!
Please, comment and criticize.
Step 1: Get the Supplies!
You will need:
Kingston Data Traveler mini fun ($13 to $30) from amazon.com:
A old laptop keyboard or some keys.
Tape. Optional if you (Like Me) do not want to make this permanent.
Xacto knife. Maybe a screwdriver (not philips head) or other prying tool would work.
That is All!
