Motor is: Jameco Part no. 2128219 (Jameco.com)
This is powered by one D cell battery.
STEP 1:
The Jameco motor will slide into the slot on this base--just solder two small wires to the motor before you insert it.
STEP 2:
Insert the motor in the base and push the cross beam onto the motor shaft. All parts should friction fit.
STEP 3:
Print two seats and drill 1/16 inch holes for fishing line "ropes."
STEP 4:
Drill holes in the top rod to match the holes in the seats.
STEP 5:
Secure the seats with fishing line.
STEP 6:
Glue the frogs in their seats--no seat belts here!
STEP 7:
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.
