Electric motorbike build

As a designer and motorcyclist, I had the idea of building an electric motorbike for a long time. The opportunity arose when I was in my final year of an honours degree in industrial design at Victoria University. I rode a 1987 Honda VFR400 to my lectures and the bike started having engine problems. I pulled out all combustion-related components and sold them. By the time I had a plan for an electric motorbike laid out I was part-way through a post-graduate diploma in Computer Aided Design (CAD) at Christchurch Polytechnic.

Build Small Boat Trailer

TO BUILD A SIMPLE trailer for a small light, runabout of 10ft to 13 ft long by about 5ft wide (3-4 metres long by up to 1.5 metres wide) this design is ideal. It is suitable for a dinghy, tinny, Parkercraft or even your children’s yacht. You can adapt this economical design, but componentry is not cheap, so keep it simple if you want it to remain as affordable as possible.

Gantry crane for model railway

STEPPER MOTORS are to conventional DC motors as computers are to calculators – in other words, much moresophisticated. The ability of stepper motors to specify rotation precisely both by velocity and angle opens new doors for movement control. The downside is that to get the most out of these little beauties, you need ancillary digital-pulse control circuits, a fact which may deter some sheddies from exploiting their numerous advantages.
