http://www.cryptoanarchy.us/store/index.php?route=product/product&product_id=64The Arduino open-source microcontroller platform can be programmed and equipped to perform a nearly endless list of functions. It's the best all-around centerpiece to a modern electronics project. Arduino is best used for is straight-up fun - the open design means Arduino board is suitable for almost all projects, and add-on "shields" extends its abilities with ease. The Arduino Duemilanove ("2009") is a microcontroller board based on the ATmega328. It has 14 digital input/output pins (of which 6 can be used as PWM outputs), 6 analog inputs, a 16 MHz crystal oscillator, a USB connection, a power jack, an ICSP header, and a reset button. It contains everything required to support the microcontroller, simply connect it to computer with USB cable or power it with a AC-to-DC adapter or battery to get started. USB cable for connecting PC is included. The Duemilanove is the latest series of USB Arduino boards
