Finding the center of an elipse (I guess) with random points on the circumference? Answered
First thing to note is that this is NOT an assignment for school, it is a real life issue.
I'm trying to make a collar for a little laser diode module which has proved to not be centered (as expected, it was only about £5). After sticking it in a lathe pointing at a wall (the wall isn't parallel with the lathe thus making it an elipse problem) and spinning it by hand, I get a wobbly circle/elipse shape which i then marked out on a sheet of paper to find a center point from which I can find how many degrees off it is which will allow me to make a proper laser re-alignment collar.
