Edimax 3G-6200nL & Raspberry Pi

I am sharing the setting I recently got together. At the time of preparing it, it makes much sense to me. After completing it, I found it pretty useless; but maybe it gives some inspiration to someone to do similar thing for a more useful project so I am sharing.

First I flashed my old Edimax 3G-6200nL with OpenWRT, details are on the OpenWRT forums, a guy did an awesome job to put together the trunk image.

'Tho the configuration of the router was very hard and painful due to only 16 mb of ram on the device, many resets has been issued till I am done with it and disable the LuCI for good for some more space in the memory. The model 3G-6200n has 32 mb of ram, just a reminder.

I used the router's Wi-Fi to connect to an AP. Share the connection through its Ethernet. So Raspberry Pi gets internet wirelessly (well kind of... lol) and used the router's USB to power up the Pi, strangely it did the trick no problem. I am using only one mini blutooth dongle on the Pi for both keyboard+mouse. But I also modded the Pi with a very mini fan and a cooling plate, fan operates from the gpio of the Pi itself as seen in the photos.

So what do I have here?

2A@5V adapter of the 6200nL powers up both the router and the Pi as in such configuration. I have a Linux ARM PC with a dedicated router which consumes as little as 2A@5V.
