We (JSConf organizers) are starting something similar (focused on bridging software/web developers into Makers) with RobotsConf http://robotsconf.com/ Would be happy to collaborate on what works/what doesn't -- handle is the same everywhere! Great job on the launch btw.
sure, we plan to have tracks for beginners too, also as making things is not only about coding and soldering we will have a lot of different opportunities for building and tinkering with stuff!
