The Zero-Blade Technology is largely inspired from the sailboat and is likely to increase the efficiency of the current wind power conversion devices. The blades are replaced by a sail-shaped body while both hub and gearbox are removed. Instead of spinning the blades’ rotor, the wind is being harnessed by a sail which follows a non-rotational back and forth motion. Such movement follows a knot path and allows the conversion of the majority of the kinetic energy into mechanical energy (using pistons). The same is then converted to a hydraulic pressure that could either be stored (in hydraulic accumulator) or instantly converted to electricity via a hydraulic motor and a generator. Thanks to the aerodynamic shape of the Saphonian, the drag force becomes the driving force of the system while the lift force becomes almost nil.
the This is a great little, Arduino compatible board, which has an XBee slot on the back, making it cheaper than purchasing an Arduino and XBee shield and also giving it a much much smaller form factor. It is compatible with the Arduino API although you need to download the Funnel library as it has some other functionality. – well worth a look
It based on the original design from LilyPad Arduino v1.6. It has connections for a Lithium Polymer battery and includes a charge circuit over USB. An XBee socket is available on the bottom of the board

» DS18B20 Temperature Sensors and Arduino
Spent the day working with DS18B20 temperature sensors and getting an Arduino to read the data they spit out. Lucky for me and you, we have the shoulders of giants to stand upon as we copy and paste some magical code to get us started
