Thank you for the interest, Gerald.
I have uploaded a circuit diagram, and will be working on explaining
what's what there
BTW, I did the drawing on an XO 1, using Inkscape in Gnome. Slower than
the quad core, but works!
let's ask Jerry (no pun: his website is http://askjerry.info) for the
frame design - he has also a nifty tractor body design there.
Hey Jerry! do you have handy the blueprint of the tricycle that we may
share it with the friends here?
