Hi Isaac,
Thanks for asking.
I have not yet decided what kind of motors to use.
I like to use solenoids as I see that it works well with an electronic padlock that I have.
I am trying to figuring out how they can supply the high current and voltage (12V/1A) that is required for this bistable holding solenoid. See my post #16 above.
I think that they use a square wave to feed a an inductor, who in its turn charges a big 4700µF capacitor. Ithink that the capacitor is then when discharged able to supply the high voltage and current for a short amount of time, but enough to drive the solenoid.
It seems to me quite cumbersome, and I don't want to use coils. Is there any other method to achieve the same?
Thanks!
