I made this airplane spinner for work. We make video surveillance SW for large business/stadiums/Towns.
This is used to see if the cameras have any ghosting effect and to see if it is a fluid motion.
I Thought this would be nice on a layout wit 2 or 4 airplanes/blimps and even some action figures like Superman?
It uses a 115VAC disco ball motor that is 5RPM and cost about $10.00 or so.
If there is any interest I can post pictures on how I built it for ideas.
Have video but having problems going from my I pad to here.
