That sounds like a good tip from Dave - have you found relevant websites, blogs, magazines to contact? Then of course finding people who are interested in programming and the technical side of things on social media. I'd guess the people in your team could look at the channels they use themselves and use those to tell about the campaign.
Notice you have a twitter account which is a good. Have you looked for relevant communities on other channels like LinkedIn, Google+, Reddit and other forums. Thinking technical people, would there be channels on IRC worth getting involved in?
What do people think, how important is it to have a Facebook account linked to their Kickstarter? I noticed there isn't one linked on your campaign currently.
Good luck
