There’s something to be said for the 'If a little is good, more is better, and too much is just right" approach to design. I tend towards extremes so it’s either that or KISS.
Cool! I’ve always liked the cabled out builds like that, really cleans it up and allows for putting the control box in lots of locations. I really want to do something like this on my 3d printer even just to clean it all up but probably not worth the effort there.
The thing with the ghosts are tricky.
I am in good hope for Halloween this year.
The functions are:
Doors open/close via two servos
LED stuff blinking etc as in the movies
Smoke generator via electric cigarette and small vaccum motor
Rattlemotor
Radio controlled foot pedal (Not on picture)
Soundboard
Once finished I will post an update here But I can tell you it is a hell lot of work.
