I see a number of people are showing interest in OSD. I have uploaded the OSD system I've been using since 2003. If there is enough interest I could provide a few boards to those into surface mount soldering.

This is link to a short video of it in action. A little windy and not the best video link but you'll get the idea. The board uses a PIC processor and a STV5730 video overlay chip. It uses a switching power supply and is very efficient power wise. Designed to be used on very small UAV's.

I was launching it off my roof and recovering in a soccer goal net. I launched it one morning when the wind was calm on the ground and blowing pretty hard just a 100 feet up. I got lost over my neighborhood and ended up crashing a mile away. Thats when I programmed the unit to give me a heading and the distance back to my launch point. The distance displayed is in 100's of feet. Power is percentage of power applied to the motor not rpm.
