    I'd love to find a wireless solution similar to uController's PropNIC.
    I'm considering pulling apart a Ethernet-->Wireless adapter and adding it to my setup,
    but it seems silly to have a card with a MAGJACK, then a pigtail to a wireless device.
    (Might be the cheapest route though.)

    Well I could design a board that has the device that Ariba listed. www.ewiznet.com/goods_detail.php?goodsIdx=135.

    I can imagine other parts including memory, keyboard, VGA, and mouse ports. I can have 5 boards made for under $150. Perhaps we can come up with a list of parts and Ill put it all together.

    there is a place close to me that is cheaper for really small runs. if you make for spin studio I will buy with parts. if there are less then 5 wanted I can get you a quote at the local place. it was listed in forum "parts" made by me if you want to look them up.

    WIZ812MJ does not look like it has any of the extra features xport has like acting as a server.

    The Wiznet chips are just hardwired tcp/ip stacks, so all you get is an interface to create tcp/udp sockets. You still have to implement all the application protocols above that (dhcp, dns, http, etc).

    The xport implements dhcp, http, and telnet for you. The xport is by far the easiest to use, but unfortunately that makes it also a lot less flexible. My main complaint is that it only supports 1 tcp socket at a time, and has a slow socket close time.

    The enc28j60 is just an ethernet mac/phy controller, so you have to implement everything (including the tcp/ip stack). It's the hardest to use, but it is also the most flexible solution. The main issue with using the enc28j60 is that the base tcp/ip stack takes ~8.5KB program memory, which means you'll loose some of your application code space.

    ok. Well here is a question. What would be involved with this ic to make a web page with check boxes that controled leds? Would be a great demo on how to use as server.

    i am already planning to use over 50 propellers. 1 more to control the web interface is not a big deal.

    Take a look at the ybox2. The bootloader and most of the applications for it have a built in webserver for configuration purposes. You basically receive the request headers from the browser and reply with html. The API used to access the tcp socket is almost identical to FullDuplexSerial.

    Here's a screenshot of a file manager webserver app I wrote running on a prop: harrisonpham.com/dp/system/files/ScreenShot162.png.

    don't tell anyone i told you this but you can get 4pcb.com to make you multiple boards for the price of 1 by compiling them onto a single sheet and then cutting them apart. Need the paid version of eagle to do it though.

    I Looked it up and I can get 20 boards(2"x1") made locally to me for $200. I need to get a few other boards made up also. At that price I can take 10 of them. Again assuming that it could be made compatible with spinstudio(ucontroller.com)

    1 thing i forgot to notice is that this is a board with everything on it already you just need to attach wires from several of the pins to your development board. do we really need a pcb made? do we not just need to connect to J20-1,2,3,4,20?

    looking again I am wrong about what pins to use.

    I have not played with serial communications other then writing to the eeprom in my id object and using counter ics. what needs to be hooked up?

    if you are looking to make a board with large flash memory and everything to make a solid state server I will buy one. spin studio would be silly.
