ABOUT THIS PROJECT


Tell us briefly about your project. Is it a work of art or does it serve another function?

Its an Electric Go Cart! Loads of fun to drive and plenty of torque to get you up and over anything. It has a top speed of 22mph and a range of over 5 miles. Powered by 2x Turnigy Brushless outrunners it has an 8S2P LiPo pack. The steepest hill I have climbed had a grade of 14% and it went up that no problem. It took me about 4 month to build on and off. Some of the tools I got to use while building it were drill presses, a water jet, a mill and a TIG welder. See my build log at www.builtbyben.net

When did you start working on this project and how long did it take you to complete?

I have been working on the go cart since this January. First I made models in Solidworks of the go cart then I bought/made the parts. Next I assembled everything - realized there were changes to be made and worked out a lot of kinks. It has required machining and soldering of almost every part involved.

What was your goal in building this project?

To learn how to build an electric vehicle as well as the individual components involved. Now that I know how to build this one I hope to built a second version (with the 1st version parts) to make it run better and go faster.

Does your project help to solve a problem? If so what problem?

You could use it to commute to work, but really it has very little practical purpose. It exciting to ride and even more fun to build.

What makes your idea unique?

Electric go carts have been built by lots of people before including the people who designed the original ground work that this go cart is based on. I am not claiming in any way that this go cart is the only go cart like it.

In what capacity are you using bearings and what type of bearings?

I am using bearings in the steering for the front to wheels and the steering shaft. Both of these spots use sleeve bearings.

What is the most important thing you want people to know about your project?

I am an 18 year old engineering student who has a passion for building things and learning about new concepts.

How will you use the $5,000 prize?

I would use the prize to buy better parts for a second go cart and race it in the Power Racing Series at the upcoming Atlanta Mini Maker Faire. Then with the leftovers I would try and teach other interested people at my school how to build go carts and spread as much knowledge as possible.
