Here it is, at long last. The Soapbox proof of concept takes to the road. Actually, to the parking lot. It’s a lot safer. 
I promised video, didn’t I?
First of all, a simple systems check:
Tonight I tightened the transmission chains, they were falling off on tight curves. Also adjusted the long board to center the mass a little bit more, the tail was way too heavy. And switched the sealed lead-acid batteries with some lead-gel batteries to increase power.
And after that, a few rides and cartwheels around the place:
Not bad, for an electric vehicle that is completely unbalanced and has power controllers that run away in unpredictable manners…
This thing is very much like riding a go-kart. I bet that I can get the same thrill at a quarter of the speed…

Dizzy yet … I am just watching

Yep… very high nausea potential. But it is FUN to ride!!
Right now, with such little control over power distribution between the two wheels, I can’t go faster than that. Maybe when I put in the seat I can risk a little more g-force.
Funny how you really can’t escape Physics; If I block one wheel with the brake and use the other one to spin, the blocked wheel is obviously the center of the rotation; but if I let go of that brake, then the mass center (me) becomes the center of rotation… with the unpowered wheel spining backwards. This is a Physics lab on wheels. Cool.

COOOLL!!!…
make sure you add an acceleration sensor to avoid being spit out of the seat

If you take a look at the next post, that’s exactly what I’m doing.
