Ubiquitous wireless networking does more to create a nano-sensors everywhere future than cheap supercomputing. Micro-controllers have had more than enough computing power to tell me the temperature in the back yard with battery power for decades now. It was sending the data anywhere usefull that was hard. As little as 2 years ago, $50-$75 was about the cheapest I could put a project on the internet, wired or wireless. Today its about $5. You can buy the whole little computer in the form of a TP-Link router running OpenWRT for about $22. I have seen the future and its made of wifi.

  Here you go. How bout $1.46. This assumes of course that your project has USB and you know how to handle the Ralink chipset. If not, just buy the TP-Link 703 and hook it to your arduino. http://www.amazon.com/SANOXY-USB2-0-Wireless-802-11-Adapter/dp/B004I8B8Z6/ref=sr_1_4?ie=UTF8&qid=1333957173&sr=8-4 http://www.amazon.com/SANOXY-USB2-0-Wireless-802-11-Adapter/... If you want the whole computer instead of just wifi, try this: http://www.volumerates.com/product/tp-link-tl-wr703n-openwrt-compatible-pocket-11n-150m-3g-mobile-wireless-broadband-router--blue-ship-with-openwrt-pre-installed-upon-customers-request-103048 http://www.volumerates.com/product/tp-link-tl-wr703n-openwrt... OpenWRT preinstalled for your convenience.

    Cool! Just bought a tp-link wr703n for use as an Arduino wifi bridge (24 USD). We'll see how it goes. Thanks for the tip! That Ralink USB dongle looks like a great way to hook the Raspberry Pi up for internet, too.
