I wanted to make a soft robot like appendage.
@VijayVigyanShaala suggested use of high voltage on films causes the film to deform.
So, first step is to generate high voltages.
I decided to use my aeroponics mister controller board which generates 100v. Added 2 doubler stages and got 415 volts no load. Here is a pic of the bread board. I will add 3 more stages to get approx 3500v. Hope the bread board does not arc.
@prerak9 built a flyback generator and generates 12 kv.
