Well, it's good you can get past the difficulties and continue.
I have a friend who loves to design things of this nature. He will get so exited over it he then begin the demolition aspect of the build, then upon starting, get about 15% into it and only then realizes it wont work.
He will then spending days making up complicated devices to get past the difficulty encountered, which of course lead to other complications, and more research, more designing and money spent.
Eventually he loses all interest in it, and moves onto something else leaving multitudes of projects in the partially completed stage.
It's funny, and sad, but always predictable.
