Just curious, what elastic material did you use to store the potential energy?
We have been using the standard surgical tubing available. But it's a prototype, so it's undergone some iterations looking at different tubing and springs as well.

It's just a prototype, so 80/20 was easy and we had pieces that size laying around. Not sure yet what the final system will employ for materials.
We were mostly trying to ascertain the correct amounts of force, lever arm lengths, release points, force application method, and retract/release system, etc. Learned a lot and still working on it though - it changed a lot today.

I don't feel too bad for the light - it needed to be dusted off anyway, apparently
