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? ;-)

we need custom made, in order to make it hackable (open source), exposed pins that we need, simple controller, with a simple wifi and simple SD socket.
There's thousands of hardware that can do that, my issue is the software side, we need a hardware that has a software easy to handle...
The server will be accessed by only one device.
Jordi,
reduce your request into only wireless solution mabye because:
1) if you wish to make a server on a Drone, isn´t it better to transfer all the data on another server where all others can read it? Exception can be for high definition photo or video.
2) If you will have high amount of requests to the server on drone, the connection capacity will be full and very slow very soon
3) If you find a cheap possibility to send high definition photo or video wirelesly, you need only wireless board and you store all the data on a PC station only. Than the drone will be SDcardless=> cheaper,lighter,less energy consumer
I am sorry I don't speek about a ready to use solution.
@Robero this is not a flight platform. It doesn't need much processing power, but it does need quite a bit of storage (SD is ideal for this), some GPIOs and at least one (preferably two) UARTs. It should be low-power as it'll need to be battery-powered. It's also quite cost-sensitive.
@Mediadroid there is AJAX involved and a data broker of some sort between the browser-side application and the serial port.
Hi Chris,
I'm yet working on different platform using Linux Inside , depend what is the target of this device , if is similar to a parrot platform or is similar to Astec . If you want to use ROS on it or using Urbi.
I yet hack Ardrone and put a lot of code on my parrot and it work fine.
I think that there're a lot of code for x86 platform .. ROS is an example of what is available . Port that code on Arm is not so simple.
The target price depend of MOQ I'm working on ARM9 with h.264 encoder the price of module start from 80 euro for 1 pcs . Without wifi module and customized carrier board.
using a simple button and posting the form and decoding is not that difficult, lwip has examples, did this for an ARM7 project.
