Since the begining of the year a group of students and I have been working on the design and construction of an Electric racing car. We've been assisted by one of the student's grandad and a couple of the school's STEM (Science Technology Engineering and Maths) Ambasadors, one of whoms companies has provided the majority of the funding for the project.
A set of construction regs and a starter kit consisting of four 12v car type batteries (used as two sets of two to give 24v power)and a 24v Motor, is supplied by the organising body so that all the teams have the same starting point. Teams are then free to design and build the car to race.
The deadline for completion is the 20th June, for the regional heat at Goodwood.
The team have all been meeting to work on the design development and construction on Mondays after school, however progress wasn'tr as fast as it might have been so last week during half term the grandad and I had a day working on the project, I've also done quite a bit over the last few days with the aim of being ready to do some full power electrical testing next Monday.
We are at a stage now where we have a car that steers, and stops, has the mecanism for the drive system in place and the seat and harness installed. We still need to test and install the electronics, our first choice is a speed controller designed and built by another stem ambasador, but we might end up just having on and off from a foot switch, with speed control regulated with our nuvinci CV hub. We'll have to see how it goes over the next week.
Here's some pics.

but it's realy over built, made from 'e.r.w' though, so not that heavy really
