i need power source for it and so i need some light weight batteries that dont weight so much and arent super expensive.
how can I make it so that all the servos share the same battery pack
GIVEN that I will not be using more than 1 of the servo/motor at 1 time?
I know you can put a circuit in series and the currents add up,
cant I block the power for some time and provide power to the other servo (I dont care whether the unpowered servo holds position or not)
what I mean was if you have a bunch of current generators the current through the whole circuit is the super position..
Also, I have access to university student machine shop so I can use that.
I should probably get me a thick sheet of aluminum and stick the gear on there and pin a needle or such through it to keep it in place.
You want your gears to mesh tightly, but not so tight that they will bind, and not so loose that they will slip under stress, which will just wear the teeth.
