How I'm building my bi-copter with Android and Arduino

Last year I was fascinated by the "How to build your own Quadrocopter" by Lenz Grimmer and decided that somehow I should try to do a similar thing. This talk is about the way I'm building a bi-copter using lessons learned for last year's talk and also with the errors I've made so far. My journey to getting a flying device running Multiwii is not yet complete. In this talk I will present all the common problems related to the project, - sourcing for the right components - choosing the materials - messing around with software - how not to blow everything up As of today, the bi-copter itself isn't build yet, but I have almost all things ready to start building it. But I sincerely hope to have it ready for a demo in my talk at Codebits 2011.
