Looking for a neat decoration for your next soirée? How about floating fleet of glowing balloon blimps?
[Kensho Miyoshi] — an avid reader of Hack a Day — needed an art installation project in Tokyo, he came up with these clever glowing balloon blimps.
They feature a mini gondola hanging from the bottom of a regular balloon which holds a small motor with a propeller, an Arduino Pro Mini, LEDs, an ultrasonic sensor and of course, a battery. They float up to a certain height with the LEDs shining bright, and when the ultrasonic sensor trips, it all turns off and the balloon sinks gently back to the ground. The process repeats, and in a completely dark room it looks like a series of glowing bubbles forming and floating away, again and again.
To see the floaty, glowy, balloon blimps, stick around for a video after the break.
We’ve also covered a similar project recently on how to make a $13 remote-controlled balloon blimp using those micro-scale RC cars, a great project for young hackers.
