Ben, I have a spirit of saint louis novelty phone that is not working. What i would like to do is use an arduino if it is possible to make it work again and maybe add other functions and use the original keypad too. The hand crank on the side and the bells do nothing but maybe the arduino can control a selonoid to make them ring when a call comes in. You can use your imagination on the hand crank maybe a coffee grinder.
EDIT: Maybe you could add a hand crank generator as a recharger for the arduino and have a battery meter to tell you how much time you have left on the batteries.
Thanks Joe
