For those thinking about the bounce I'm getting, the problem is in twisting. The trusses are plenty stiff in the plane they are in, but when the final section is at an angle to the first section, the first section is being twisted by the weight of the final section being out of the plane of the truss. A counterweight would reduce the twist, but would not necessarily help with torsional stiffness. I think I can stiffen the truss slightly and that might help. It's not helped by the hinge pins not being coaxial. For that I will have to make a custom hinge with the pins joined. While the hinges don't directly make the boom end bounce, they are sagging and that is not helping
Cool idea. I had a thought how to help reduce the bounce by connecting a cable from the end of the support to a pulley connected to a swivel above the primary support connection on the wall with a weight on the other end of the cable. This would provide an adjustable counterweight for the camera while still allowing a full range of motion.
Bounce is a problem. I'm still thinking about that one. The boom is usable, but I may need to remake the hinge. Being a welded construction of commercial hinges, it's a little loose.
I'm eager to see what you come up with to eliminate (or at least reduce) the bounce. I'm just guessing perhaps a spring, counterweight or other mechanical idea.
I'm keen to firm up the hinge as its an experiment, and a bit of a lash up. I may also put some depth on my trusses and try to reduce twist that way. It works as is, so plenty of time for thought. A counterweight or spring might reduce the twist a bit, but I need a dampener really. I'll have to see what devilishly intricate and overly complex solution I can come up with.

Nothing to say just an obligatory boost for the algorithm. 👍👍
Thanks.
