From an elective course at Rotterdam University of Applied Sciences, I was given the assignment to make something in which I had to use at least 2 machines.
I then decided to make the Warp Core of the USS Enterprise NX-01 because I'm a big fan of Star Trek and I've always found this to be a fascinating thing from the series.
I also made an Instructable of this project where you can read all about this whole project and how you could make one yourself. This is the found via at my instructable
