Shorter than previous build, more rounded ends, still controlled via wireless Wii Nunchuk. Probably as far as I can take this now apart from moulding the whole thing in carbon fibre!
Upgrades will be confined to software - better steering "feel" on corners and so on.

Video of myself and others riding it all day long in a street carnival in Oxford July 2010, the "Cowley Road Carnival." Battery still showed full charge at end of the day on the LED display and took just 2 hrs on charger to genuinely bring it back up to full charge.
Self balancing skateboard carbon deck opened: 88 LiFePO4 cells. The battery management circuit board was in the deck (which is why old one was longer). In this one it is under the main deck.

In the end I merged this with my pneumatic tyre version. Ended up a bit bigger but the combination of long battery life from the deck full of batteries, plus the pneumatic tyres for rough surfaces proved worth making these changes.
Tip: Using a vacuum cleaner when cutting (dremel disc) carbon fibre is very good idea as fibre dust very nasty. However, don't use a Dyson, the carbon particles do get through the cyclones and do get into motor which then emits clouds of smoke, sounds very sick, then stops - forever!
