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).

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... ;)

Hello,
I'm planing on using openCV to do some calculation (3D scaning, movements, ...).
when I'll have time... :D
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.
