OHM 2013
From London Hackspace Wiki
OHM (Observe, Hack, Make) is the latest in the series of four-yearly Dutch hacker camps. 3000 people in a field, with power, internet, and beer. Come and join the London Hackspace/EMF contingent!
It runs from July 31st - August 4th 2013, although some of us will be there earlier to help set up.
i've added a village for EMF. if you intend to do or display something, submit via the CfP so we know about it. i may be able to facilitate your needs too - amran
