Hello OSHUGgers, I hope this is an acceptable announcement for this list.
Electromagnetic Wave (May 5th) is a day filled with talks and workshops for those with an inquisitive mind or an interest in making things, held on a converted East German fishing vessel moored in London. https://www.emfcamp.org/wave Talks so far include Zeppelins, Wifi radar, open-source vacuum cleaners and WebGL.
As part of the team getting Internet to the boat (harder than you might imagine) I've also managed to get a TV Whitespace licence for experimenting. Whitespace will soon be open for us all to use, and is particularly interesting for the Internet of Things.
As the country's (world's?) first "popup" whitespace network what we're looking for is experiments, interested people, Internet of Things ideas or skills. Read more about it here: http://love-hz.com/post/48999576581/emw-event
Hope you can join us or even just offer ideas
Ben
