In the first instalment about the self-balancing single-axle electric 'vehicle' in the Summer Circuits issue we explained the operation of the electronics. There is, of course, also some mechanical construction required before the ElektorWheelie is ready to be used. The ElektorWheelie is delivered as a kit containing all the necessary parts. The kit contains all electronic bits, the batteries, the steel housing, the wheels, the motors, the control lever and an economy battery charger. The printed circuit board comes completely assembled and ready mounted in the housing, just like the motors. In this article, with the help of a few photographs, we describe what remains to be done by you.
