Here’s a really tiny r/c blimp that doesn’t need several cubic feet of Helium to get off ... based on an 11-inch party balloon that can provide about 11 grams of lift. This doesn’t allow ...

It’s also renewable. “So, we fill the balloon with helium or hydrogen to lift it to altitude, and after that, the balloon is sealed so that helium stays in the balloon throughout the duration ...

Above the duck, a balloon, constructed of paper and fabric, provided the lift necessary to carry aloft ... This double balloon helium/hot air system, however, remains among the most successful ...

The balloon is called a Gryphon Stratolite and is designed to operate between 45,000 and 75,000 feet, according to World View ...

But you can still fly your own with a helium balloon and some electronics. One notable project — the Blimpduino — has evolved into the Blimpduino 2. The open-source software is on GitHub.
