I've been working on some UAV stuff and thought I would share a little bit about I'm doing, and also see if anyone would be interested in getting together and working on a joint project.
My end goal is to do a solar-powered, high altitude, high speed UAV with a wifi-based ground station (possibly another protocol like zigbee 900mhz, if wifi proves to be impossible). I would be happy to break any of the following: Flight above 30k feet, Breaking 400mph, 10 hour flight time, wifi-based fpv and my pie in the sky goal is to fly at 100k feet @ 900mph, which is the orbital speed at that height. While technically possibly, I doubt its feasible. :)
I have a couple of RC planes, a 400-sized electric trainer (currently smashed, heh) and have a 2.6 meter "Super Easy Fly" powered glider that is on the way. In the end, due to the speed goal, I'd like to have a custom designed plane that will probably resemble the X-43A hypersonic scramjet test plane.
For the ground station, I have a telescope mount ordered that will be here next week that has drive motors, a 24dBi parabolic dish antenna, a laptop, wireless routers (one for the plane, and possibly one for the ground station), usb wifi adapters (5 of them, so that I can compare power levels and automatically point the dish antenna), and a surprisingly good IP-network camera. The camera and router run from 5v, so I also picked up a Castle 10amp BEC that I can use to power everything.
I've also got a couple LiPo batteries on the way, a 14.8v 5000mAh and a 11.1v 4400mAh.
This weekend I intend to cobble together some of the parts and put the the router, network camera, BEC, and a small LiPo battery in a plastic container at the top of Mission Trails park and test the range of the wifi setup that I've got. I can see the top of the mountain from my apartment, which is about 1.5 miles away, so that makes it an easy target. :)
If anyone would be interested in collaborating, please send me a message or post a reply. Also, feel free to ask any questions or note any concerns.
