I am currently building a animatronic project pretty similar to Adam's C3PO build and I'd like to copycat the idea to use a powertool battery to power all parts.
My question is, in that video it looks like Adam is powering all parts from Arduino to the lights off of one 20v 1.5ah battery. But does he also powers his two 24v servos from it? I am especially curious as he uses a buck converter to step down the 20v to 5v in his circuit. So are the servos powered separately then?
I would love to have your opinions on that and if someone got the circuit layout somewhere I would be happy to have a look on it as well.
