The heart of the blimp is an Arduino ATMEGA328 on a custom designed board that I designed, along with the Blimp control APP you can find on the google play store, just search n1ir for the app. The app was designed with MIT APP Inventor and sends out a simple text string to control the motors and servos.
This year we got the weight down to 67 grams with the battery and can fly with just one helium filled balloon. This has been our best year yet, four years ago we started with four balloons, but with constant redesigns we trimmed the fat. We have also changed the material used in our Bi-Polymer Objet260 3-D printer to a lighter stronger materiel.
