Here's a small selection of what I get up to in my spare time:
Electromagnetic Field
In 2012, I helped start Electromagnetic Field, a weekend camping festival for geeks, makers, hackers, scientists, and those with an inquisitive mind. Loosely inspired by the big German and Dutch hacker camps, EMF happens every two years and has grown to over 3,000 attendees.
EMF is an entirely volunteer-run non-profit and now relies on the work of hundreds of amazing volunteers. I am a director, principal event organiser, and treasurer.
Limehouse Labs
I'm a co-founder of Limehouse Labs, a small hackerspace in Limehouse Town Hall, east London.
Social media bots
I like building social media bots, especially those related to space. The bots I currently run are:
Spacelog & Earth Lens
I'm a big fan of space exploration and its history. As part of the lovely /dev/fort, I managed — twice — to convince a group of smart web people to help me work on space-related projects of mine, for a week. In a fort.
At /dev/fort 5 we built Spacelog, a site to browse the transcripts of NASA's human spaceflight missions in a lovely format. At /dev/fort 8, we built Earth Lens (sadly no longer online) to browse astronaut photography of Earth.
London Hackspace
I co-founded London Hackspace in 2009 along with Jonty. It's a non-profit community workshop (or Hackerspace) for people to share knowledge and equipment, which now has more than 1200 members. I was a trustee of London Hackspace for seven years, and I'm still a member.
Everything else
When I get enough time to work on other projects, I have a particular interest in software defined radio, brewing beer, hydroponic gardening, and lasers.
