Ruby60 0 Posted November 7, 2013 Report Share Posted November 7, 2013 Question for all you electrical brains out there: What kind of circuit can I build to convert 120V AC to 4.5V DC? I picked up this 5ft tall animated Santa from the Rite-Aid today. The animation is a moving mouth which moves in sync to several Christmas songs and a Christmas story. The mouth movement and sounds are powered by 3 AA batteries, so that's about 4.5V DC. I am going to try to animate the arms by installing a deer motor and some linkages. I'd like to power the mouth from this 120V AC deer motor and eliminate the batteries. So can someone please draw me a schematic or explain how to convert 120V AC to 4.5V DC?
