Hey all. I have an old rotary telephone that I've been taking apart to repurpose for other projects but I was looking at the ringer on the phone and was wondering if I could hook it up to battery supply with an on off switch and a temporary on button to make it ring.
Is that possible? Any ideas on the amount of batteries needed? I always thought the old phones ran on a low voltage power supply but I really don't know shit or if this will work.
