Hey everyone, just for quick introduction whilst im here. Im a College student enrolled in a Welding program. One of my shop classes are allowing us 10 weeks total, (1 class a week 3 hours long) to build ourselves something of our choice. Everyone is doing tables, chairs, fireplace. Something im not particularly interested in, for me that is too original and to put it simply, boring.

I'm looking for fresh ideas, and perhaps some plans to go with it.

I do have an idea or so. I had the thought of building a unicycle with a bike-style frame on it. The pictures below are Electrically powered unicycles where i got the idea from. I was thinking about building something similar but without the fancy computer equipment and stabilizers, maybe even thought of putting a small gas motor on it.

This is my first time fabricating something so i am very new to it. If you guys had any help for ideas or to help me with the unicycle that would be greatly appreciated. I am willing to spend around $100-$150 on this project(Metal material not included) The metal materials are already covered by the school. However, i can not order stainless or aluminium or sheet metal. So basically mild steel.
