"A set of bathroom scales lives underneath the coffee machine in the kitchen, connected to an Arduino Ethernet that measures the weight, calculates the number of cups of coffee in the machine and sends the data out to Xively. All the measuring electronics of the scales has been bypassed and the Arduino measures the mass of the water in the coffee machine by reading resistance change from the strain gauges at each corner of the scales, via an INA125 instrumentation amplifer. Detail on connecting the instrumentation amplifier to the Arduino is shown in the ArduinoInstAmp repository in GitHub and I’ve written about it previously."

"I recently designed “Roomduino” to control electrical devices in my room from internet, it's a solution base on Arduino, I custom designed two boards for the small system, the first is a "network gate" board, which is like a hub or a master node, built by an Arduino compatible board and an ethernet board. the second board is a "network node" board, which is a electric switch board with 2.4GHz RF board for communication with "network gate", it controls electric switchs of your devices. A "network node" board must be fit into your electric socket, a DIY work is necessary in this step."

$90+ Kickstarter. Raspberry Pi & Arduino compatible. It's a little fully-certified cell phone board that you can snap into other boards, e.g. your project.

A WiFi enabled board that can be programmed with Javascript. Lots of ports. No word on pricing, which I guess is the key thing.

Who wants an Intel-made open source Atom board without WiFi for $200? (Newark says $285 but +David Anders informs me that Newark has the price wrong and the other other vendors have the correct price).
