Space Camera 4 (TEDx)

7 Nov 2011


For TEDx 2011, I was asked to do a talk about the ‘space camera’ projects. I decided I’d do a live launch during the talk, and show the images live.

We had lost connection to the payload, but someone in Rotterdam found it on the street, and called us up for the $100 bounty. Immediatelly when it landed, a woman got it. It landed 20 meters from the river Maas in Rotterdam. She tried to call us (i didnt pick up, I was attending a TEDx Delft talk, she thought it was a bomb, so “She opened it ” (=ripped the whole front off). Then she called the police, which said “Oh yeah we know about that, it’s not a bomb”, then I called her, picked it up after a 15 minute drive!
