Tp-link wr703n as Openpilot (and maybe other) wifi telemetry link, and HD webcam broadcasting TUTORIAL

Hello

I found that lot of people discovered this new feature of the wr703n flashed under openwrt : It is able to stream an USB webcam (soon a Gopro using an easycap) and also to make a bridge between a serial interface (USB according to CDC driver or 3.3V TTL).

see : http://www.diydrones.com/profiles/blogs/hacking-a-rc-helicopter-for...

Here is the tutorial (3 parts + 1 part unbricking ;) ) on Openpilot Forum : http://forums.openpilot.org/blog/52-fertitos-blog/

So I started a TUTORIAL to help those that would like to add this feature on theyre drone and start developping new sensors :

I'ld like to work on a laser line avoidance system using the webcam :

If you have question... ;)

This is very cool.  I think the TP-Link uses the AR9331 SoC which is a pretty good little system.  The company I work for sells a product based on that chip.  The only thing you will run into with this is that it is a 1x1 802.11n chip which means that it will use more airtime to send data.  One tip, keep the radio in 20MHz mode, the Tx Power will drop by 3 dB if you put it in 40MHz.  Good luck to you on this and I look forward to seeing the results.

Excellent work. I wonder if OpenCV could be used to do some really cool stuff with such a setup: http://opencv.willowgarage.com/wiki/FullOpenCVWiki

Hello,

I'm planing on using openCV to do some calculation (3D scaning, movements, ...).

when I'll have time... :D

Nice work!

You mention Easycap video for Wr703N. Did you manage to compile Easycap adapter driver? Is it possible to get it from you? Would like to include in
