Help wanted for top secret project

Posted by Jordi Muñoz on January 2, 2011 at 5:00pm

Happy new year folks!

3689383891?profile=original

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? ;-)

    @Matiaz Cimpersek, the PIC Wifi server looks great, almost everything we need to start. Thanks!

    I've been looking at this also, but GumStix, does not support AP mode that I could find.  The only thing I found was the pandaboard with a new firmware load for the wlink 6.0 that handles up to six connections.  One of my other ideas was use a USB Wifi and a beagle board or something simpler, but have not found a USB dongle that supports AP managed mode.  ie www.pandaboard.org

    @Ravi the WiFly module is not a generic WiFi network device, it's a device endpoint.
    @Matjaz the BlackWidow uses the ZeroG module; ZeroG were acquired by Microchip and supply of the modules has been under a cloud for a while now. Documentation also seems difficult to come by.
    @Ryan the RB411A is definitely nifty; it could really use a few GPIOs though.

    @lionel Gumstix may be the way to go, but is really expensive, maybe is because has a lot more than we need in terms of power.

    Netduino? 32-bit processor, dot.Net dev environment, Arduino-compatible pinouts.

    Take a look at Microtic, they make pretty generic hardware and a "Router Os" that's Linux. also fits your price point.

    Consider a PCEngines Alix card http://www.pcengines.ch/.  A 2d2 with a mini-pci WiFi card runs around $130, which is a little more expensive than some of the other options, but unless you are going to purchase 100's or 1000's you will come out ahead owing to the ease of software installation and development.  AMD Geode (x86) processor, CF card slot, 256MB of ram.  Voyage Linux (linux.voyage.hk) provides a debian based platform that runs with a read-only filesystem, but uses standard ext2/3 fs do you can quickly flip to rw and use apt-get to install additional software.  A 2d2 with a WiFi card runs at 3-5W, board requires 10-18v.  They do not have an SD card slot, but there are 2 USB ports, and depending on what you are trying to do, you might be able to use the main CF card.

    would this help in any way?

    @Tom Pittenger
    yes, abs. true - the but is, for sw development there is very little memory left.
    to me i would go the opposite way, instead of saying what micro has to used chose the development platform first ;-)

    i would still opt for a cortex design with support external memory.
    the more important question is what peripherals you are going to use...

    and when using linux each peripheral needs a low level driver.

    i would keep the entry low to start with.
