Self-balancing skateboard robot

XenonJon received a truckload of attention for his skateboard/Segway-style balancing platform which he created, making quite a splash at the Makerfaire in Newcastle. Since us humans are all about improving ourselves always, he has made up his mind to build a cheapest version possible without it being complicated at the same time. While the build is documented very well, you will still need to email him personally for the Arduino code.
