Making the Wings

  1. Bend sculpture wire to create 2 identical wing shapes. Try to conserve amount of wire used to minimize weight. Use epoxy to secure the ends.
  2. Attach servo accessory to the ends of the wings keeping check of orientation and secure with epoxy. Secure with small pieces of tape if necessary.

  4. Cut out identical pieces of Mylar or foil and attach to wire shapes using a glue gun. Leave the foil loose when attaching so it takes a hemispherical shape when wing is flapped.
  5. Attach wings to the servo.
  6. Wire up the servos using wire-wrapping wire.
  7. Plug the control wires from the servos to digital pins 2 and 4 and connect to 5V power and ground on a breadboard and/or Arduino Uno (for testing)
  8. Upload a basic servo program to check wiring making sure that both wings exhibit identical motion.
  9. If wings are not moving check continuity in circuit, secure connections and try again. If circuit works, disconnect and prepare wiring for Arduino Mini Pro.
  10. Insert servos through 2 small identical plastic cups and glue to secure in place. Make sure wings move without any obstructions. Cups are useful in attaching wings to the balloon and hiding wires.

  12. Mark points on the empty 36″ blimp envelope where wings will be mounted. Points should be in exactly opposite on the balloon surface and provide balance to the blimp.

  14. Cover the cups with Mylar foil using glue gun.
  15. Fill up 36″ Mylar envelope with Helium.
  16. Attach servo cups to the balloon using small pieces of tape. Let wires hang loose.
  17. Cover the tape with pieces of Mylar or foil.
