As you see in that video the pictures some are a touch long in aspect ratio it was running to fast ..... my drum was never synced all manual control for the stepper motors line mirror and frame glow drum speeds.
You could do a system read the posts here ...

I like you drawings it reminds me of the art in the Secret Life Of Machines

The electromagnetic spectrum has no theoretical limit at either end. If all the mass/energy in the Universe is considered a 'limit', then that would be the only real theoretical limit to the maximum frequency attainable.
