getting a basic stamp to brodcast a webserver....

shanker

Hello all so i am new to this hole things. But i want to get a basic stamp to broadcast a web server that you can log on to. using wireless. almost like Apache or something like that. what do you all think and could you point me in the right direction ?

You could start with the PINK module here: http://www.parallax.com/Store/Microcontrollers/BASICStampModules/tabid/134/txtSearch/pink/List/1/ProductID/40/Default.aspx?SortField=ProductName%2cProductName

And grab an ethernet to wireless bridge here: http://www.amazon.com/D-Link-DWL-G810-Ethernet-Wireless-Adapter/dp/B0000CEPCH


While not as portable (due to the bridge) it's still valid as a proof of concept.

http://www.sparkfun.com/commerce/product_info.php?products_id=8665 do you think something like the xbee would work ? for the wireless.

xBee works very nicely for wireless. Use the xBee Pro because of the greater range and transmit power. I suggest you use the older series firmware (Series 1 - www.digi.com/products/wireless/point-multipoint/xbee-series1-module.jsp) because the newer "mesh" stuff requires a network controller xBee device.

Remember that xBee is not the same as WiFi. You'll need an xBee unit at the PC end of things.

sweet that makes a world of seance thanks for the info...also thanks for the link that is even cheaper than sparkfun wow thanks

Hay mike so you are saying that i would have to host apache from a main PC and brodcast it over to the xbee pro device do you know where i can find more info on this topic thanks

What I'm saying is that xBee only gives you a wireless serial connection.
It doesn't really give you a network connection in the usual sense.

A PINK module is really what you want along with an Ethernet to WiFi bridge
to give you the wireless connection. All of this takes a lot of power and will
run through batteries pretty quickly. Soshimo has the right idea and some
good links.

Note: A Stamp is just not fast enough nor has enough memory to provide
any kind of web server. The PINK has an internal processor that takes care
of most of the work.

A Propeller does have the ability to do a web server. Look at the YBOX2 for
an example of this: www.ladyada.net/make/ybox2/

There are some WiFi interfaces that could work with a Stamp, but would still have some problems with speed and memory availability.
Digi makes several: www.digi.com/products/embeddedsolutions/digiconnectwime.jsp
These are not "plug and play" in that you'd need to provide a 3.3V regulator and mounting / connection board
as well as some kind of interface between the 3.3V logic and the 5V logic levels of the Stamp.
