Happy new year folks!
DIYdrones hardware development team needs some help, if you think you can contribute in something please PM, our requirements are:
-Any microcontroller capable to handle a little web server can be used.
-The hardware must have WiFi access (behave as an access point).
-The hardware must have SD card slot (where you can store html files).
-Must be cheap (< $100).
The system must be capable to read a HTML file stored on the SD card (including pictures) and create a web server accessible via WiFi (acting as an access point). When the user is connected to the Wifi device-must type any direction like "http://192.168.1.100" and be able to load the HTML files stored on the SD. Something similar to a home router.
The HTML files must be able to read/write to the IO, analog and UART pins of the same microcontroller....
What we need from you are suggestions of the right hardware, software contributions and connections to anybody capable to help us.
Anyone? ;-)

SD card can be easy to add to almost any micro.
Many years ago I worked on a project adding an SD card slot to a product running an Atmel mega8 (I think). As I recall the SD cards have a basic serial interface that can be connected to a UART. In my case the chips UART was not available so I just bit banged it with IO lines.
Not the fastest way to get data in and out but may be good enough depending on your needs. Was for us.
to a certain extend i miss a few points from an archtitecture point of view ;-)

would it not be better to extend the apm with more functionality.
and the same chip for a ground station.
i like to reduce the wire count.
here we just increase everything :)
@Benjamin, I think is something we can do later to expand the system, but for now we just want to create basics. The board is mean to be on the ground.
Yes we are working with rabbit right now, we have successfully created the access point and load a web page using the build in flash to store the HTML file, but I still trying to do the same but from the SD card.

If you are familiar with rabbit you may help us a little bit. ;-)
Now the main point here is that we have all the means to create any board, even 4 layers. We only need the right micro, the right WiFi module and the SD slot. If youknow the perfect combination and would like to contribute maybe with
some coding please let me know...
This what I can do for you, buy you all the parts you need to build a prototype, you make it work (including the open source code), I will create a professional high end PCB and we sell it. If you are interested please send me a PM...
We can use any available board out there as an starting point, but take in consideration that at the end a custom board should be created to reduce prices.
Also, yes adhoc mode can be used, but only at 10mbps. There is a new standard out for peer Wifi http://arstechnica.com/hardware/news/2009/10/wi-fi-direct-protocol-...
http://en.wikipedia.org/wiki/Wi-Fi_Direct
The wlink 6.0 and wlink 7.0 should be able to support this feature, but the biggiest issue is getting a product to support this new mode...
@Matiaz Cimpersek, the PIC Wifi server looks great, almost everything we need to start. Thanks!
