Version 1 was made mostly out of wood. Working from my house in the summer of 2010, I didn't have any fancy shop equipment, so the most powered tool I used was either a hand drill or a Dremel. It did work wonderfully. A lot of the part selections were sourced from XenonJohn's excellent Instructable.

I brought the board to Tech, where I teamed up with Jamison and Xo and entered the board in Georgia Tech's Inventure Prize. It was temporarily called Glide Board, for lack of a better name.
We couldn't present that crudely designed and constructed board, so we created a second version.

Version 3 was never fully built. Made from transparent polycarbonate, it was to have fancy brushless hub motors.
Version 4 was designed with parts from version 1 with a significant difference: strain gauges. This eliminated the whole tilting back section.
|Ideally a PIC24H, but was hacked together with an Arduino
|Four strain gauges from a bathroom scale
|Two brushed 250W Currie electric scooter motors
|6S, 22.2 Volt, 5 Ah lithium polymer "longpack"
|Dual 25A Sabertooth motor controller
|12 MPH limited by motor controller
|2 miles or so
