I show how I built the demonstrator for my systems & stability video. It's an electromechanical pendulum, and it's kewl -- or it was, until I broke it making this video. https://youtu.be/YW33PVTYhdw -- Tim Wescott Wescott Design Services http://www.wescottdesign.com I'm looking for work -- see my website!

I got it working and glued it in place, but had to break the glue joint for the tear-down. Then I failed to fiddle it back into working again. :( Maybe I'll replace the ball bearing with a flexure, as I recommend in the video. Or, maybe I'll just put the damned thing on the shelf and cook up another video!! -- Tim Wescott Control systems, embedded software and circuit design I'm looking for work!

I think you learn the MOST on "pet projects" where you aren't arbitrarily constrained by a client's notion of what it should do, how it should work, what it should cost, when it should be finished, etc. Your money, your time, your imagination! Nothing to get in the way...

Thank you. I recall seeing you post about production issues some time back - the video & audio quality are fine.
