Open-Mesh Mini-Router - Low-Cost Mesh     As a different approach, consider: you can get an embedded Linux box with WiFi, plenty of RAM and flash, a serial port and some spare GPIO pins for US$29 + shipping (http://www.open-mesh.com/index.php/low-cost/accton-mini-router-w-power-suppply.html). There is a Linux kernel module which lets you easily bitbang I2C over GPIO, or else you can build a 1-wire master with a few extra components if you are set on that. That way (assuming you already have a wireless network) there is no need to get the XBee adapter for your computer, or you could even save many days worth of temperature measurements straight to flash or send them over the Internet rather than having to have the computer on all the time, so you save on power.     http://www.open-mesh.com/index.php/low-cost/accton-mini-rout...     tags: linux _g Brain Workshop - a Dual N-Back game     fluid intelligence     http://brainworkshop.sourceforge.net/     tags: mac linux intelligence brain Marvell: SheevaPlug Development Kit     The SheevaPlug is a development platform, targeted for use as a plug computer, and designed to run network-based software services. It features a Kirkwood Series SoC with an embedded Marvell Sheeva™ CPU core running at 1.2 GHz. This device connects to the network using GbE, offers desktop class performance, and can be used to replace a PC-based home server for many applications. Peripherals connect using the included USB 2.0 port.     http://www.marvell.com/products/embedded_processors/develope...     tags: linux ulinux sheeva GlobalScale Technologies - SheevaPlug Dev Kit     In the plug computing model, network-based software services from a desktop or laptop computer are simply moved to a more efficient device that can be left on all of the time, at ten percent of the cost. Basic examples of such services include web, email, and virtual private network servers hosted in homes and small offices. Moreover, the rapid increase in the amount and variety of digital content and network-connected devices in the home are creating even more opportunities. Software services are needed to locate, manage, secure, and share this data.     http://www.globalscaletechnologies.com/p-22-sheevaplug-dev-k...     tags: linux embedded plugcomputer Flavio’s TechnoTalk ‽ Blog Archive ‽ Hardening Linux: ...     http://geminis.dyndns.org/wordpress/index.php/2005/06/16/har...     tags: linux security
