These swinging frogs, part of Froggy World amusement park, are made from 3d printed parts and a Jameco gear motor. Parts and design files at:...
The Jameco motor will slide into the slot on this base--just solder two small wires to the motor before you insert it.
Insert the motor in the base and push the cross beam onto the motor shaft. All parts should friction fit.
Print two seats and drill 1/16 inch holes for fishing line "ropes."
Drill holes in the top rod to match the holes in the seats.
Secure the seats with fishing line.
Glue the frogs in their seats--no seat belts here!
Apply 1.5 volts (one D cell) to the motor and the frogs will swing. Put 3 volts on and they will move so fast that you can't see the individual frogs...
