John Draper and Heiner Sextro onboard of c-base space station Berlin
 John is also known as Captain Crunch.  The Captain is among  Top 10 of world's most influential hackers . John Draper was a hacker when they still called it phreaking. Here at c-base hackerspace he was our guest. For the first time we have met a person, who witnessed a nuclear blast. This was more impressive to us than the Captains anecdotes  about Steve Jobbs and Steve Wozniak.
 
 
 We made a video in the c-base robolab.
