[NetBehaviour] Helium balloon aerial photography.

Helium balloon aerial photography.

So, you’ve got an itching desire to inflate 150 helium balloons, but 
have no idea what to do with them afterwards? Well, readers Stefan and 
Michel decided to build a simple aluminum frame to mount a cheap digital 
camera and do some aerial photography. Instead of building a complex 
timing system they just attached a strong motor from a security camera. 
It’s powered by a AA and is geared really low so it only triggers the 
shutter every 12 seconds. They deployed the rig from the fortifications 
surrounding Wilemstad in the Netherlands. There are several pictures of 
the city (and the occasional envious child) on their site. If you follow 
the “continue reading” link you’ll see a couple more pictures of the 
camera mount.
