Telemetry

Last year I spent a decent amount of money trying to get telemetry to help us tune the trebuchet. I finally gave up and felt that my time was better spent elsewhere. Recently, as the weather has changed, I have started getting more and more done and started to feel more confident about what we could accomplish this year.
As a result, I have started to look back at the idea of telemetry and figure out how I can get the information that I need. I’m now at a point where I think I know what information I need and how I can get it. The hard part remains how to build something that gets me that information.
The way I see it, if I can get a device implanted into a testing ball that will read g forces, and will be able to the roll of the ball and at what point the in the swing the roll happens, I should be able to tell two important things. The first would be if my sling length is correct, that is the G forces. The nest would be what my release point is, that is the other two components. If I can put those two things together I should be all set to fine tune the machine to an optimum sling length and a 45 degree release.
I’m hoping to learn Arduino on my families spring vacation which I think will open up this area for me a lot.
