I made a blimp made of an ordinary balloon and a simple gondola. The gondola can be easily equipped to the tie of a balloon.

It includes

 - a small motor

 - a propeller

 - a microcomputer (Arduino Pro Mini)

 - LEDs

 - an ultrasonic sensor

 - a battery.

The helium-filled blimp goes up by rotating its propeller. When the distance between the ground and itself grows to a certain length, the blimp detects it by the ultrasonic sensor and turn off its motor and LEDs. Then it goes down (by its own weight) and turns on the motor and LEDs when it reaches the ground. There appears a space like darkness in the water with light emitting bubbles going up by flying these blimps repeating the cycle of this motion.

The blimps fly for about 30 mins.

Thank you for comments!

I just added a simple video. Check it out!

What size is the balloon?

Comment by Kensho Miyoshi on December 23, 2013 at 11:08am

The diameter of the balloon is about 50 cm when inflated.

That takes a lot of patience & balancing.  If someone could make a fan & sonar module small enough, it just might go all the way.

Interesting Project.  But why do you need it to keep going up and down. I would want it to maintain almost constant height and heading. Then hanging a small camera would give me flying study cam :).

I wanted to make a performance available even in ordinary spaces (not only in high-ceiled spaces). But I am also interested in the trial you have mentioned.
