A Quest! Answered
OK - first off, hello everyone!! I've not posted an Instructable for perhaps 4 years now, but I have done a fair few things in the intervening time (shortened life story to follow - if you just want details about the project, scroll down.)
Not sure when, but in early childhood I started playing around with K'NEX. I'm sure you'll all agree thats acceptable for a kid of about 5. Several years progressed before I discovered the art of K'NEX weaponry - which led me to create my first ever (and widely crap) Instructable.
My fascination for things that you have to put together to make them work has not faded - I have become involved heavily in the Greenpower Race Series for Schools (www.greenpower.co.uk, if anyone's interested - I'm Rob on the forum) and next year will probably be my last truly competitive one - I'm building the one for next year over the summer. Having looked for a couple months about what I can do next, I've come up with a bit of a foolhardy quest that sevearl people have probably already done.
The Project (hello, if you've just scrolled down) is to design, build and drive on the road an Electric, 2-seater, Hardtop Sports car with the following features: 85 MPH top speed (15 more than the Motorway limit), 500 mile range, flash charging capabilities, various mod-cons (e.g. a windscreen), some luggage spaces and a price tag of as little as possible. I'm probably going to be designing the chassis on a 3D CAD program (either Solidworks or AutoCAD) over the next couple of years, as well as getting enough money, sourcing parts, and designing the PWM (Pulse Width Modulation, controls how long the motor is on for in any given second) system.
Here is a list of what I see as I need to do:
Source electric motor
Source batteries + charging system
Source parts for chassis - Welder, rear differential, steering components, bits of Aluminium/Steel (haven't decided which) box/tube.
Build rolling chassis.
Anyhow, I will be making an instrucable and will hopefully publish it once I'm done. The whole thing will consist of my entire design process and building processes. Everything from chassis stress testing to choosing what type of dials to have.
Hope that was mostly interesting!
