Quoted from legtod2:One thought I had on the spinning rotor target was to virtualize it as a mode and emulate the spinner.
For those who have or played CE3K the rotor solenoid fires frequently and target wear of the spinner and switch can be problematic.
Maybe I will just virtual display on the backglass the spinning target values and keep the target stationary. When a trigger for spinner occures I was adjust the value of the target dynamically.
hmmmmmmm
that sounds like cheating! I have most of a CE3K roto assembly minus parts like the targets and switches if you need parts. it's just living in a box.
In my first homebrew (not completed yet) I built a roto-target like assembly using a multiple rotation servo (used in sailboat models) to run the target. it can go 3 full rotations then reverse direction as needed. I'm only using it for one target up at a time instead of 3, so only need one switch, and I know the value of which target is up because the servo positions are all mapped accordingly.
