Update 10/22/2012 - For those few who may be interested, I'm now using this software on my personal quad with ACM 2.7.3 and 2.8. This software now compiles with Arduino 1.0.1 and works with Mavlink 1.0 or 0.9. The wiring and hardware requirements has not changed. You can download the software from my personal website at this link.
Since I purchased my Arducopter last November, I've wanted to use my NTSC video camera, Remzibi OSD, and 1.280 Ghz video transmitter with my quad and experimented with different ways to do it. It was easier with Arucopter NG RC2 since Mavlink was not in use and I could generate my own serial stream to the OSD. With the release of Arducopter 2.0.x and Mavlink it was a little harder. I really wanted to have Mavlink up and running to my Ardustation tilt/pan antenna and notebook while using the on board OSD.
My solution was to add an Arduino Pro mini to my quad configuration and modify some Mavlink Ardustation software from phillip.anthony.smith to create the serial stream that the Remzibi OSD likes. The details of this mod and link to the my Mavlink to Remzi converter software is available here:
