1) Grab old sparkplug
2) Bend the ground electrode straight with pliers
3) Grab your board and head over to your car
4) Pull any sparkplug wire and plug the bended old sparkplug in it
5) Jam the sparkplug ino the USB plug thingy so that it the ground and center eletrode more or less touch the data and voltage lines and as little as possible to the outside metaly bit (insulate with electrical tape for extra dramatic effects)
6) Set up a camera to capture everything on film
7) CRANK THAT ENGINE!!!!

If for some magical reason the board survives, dip the board in gasoline and repeat step 7
9) Upload video of your now undeniably destroyed keyboard on youtube and place a link here
THE ABOVE IS DANGEROUS, DO SO AT OWN RISK I CAN NOT BE HELD BE RESPONSIBLE IF THINGS GO WRONG. In fact if things do go wrong, ill probably just laugh my ass off and send the youtube video to all my friends!
