You can easily build a barebones Arduino yourself. This project shows a breadboarded Arduino without an FTDI chip. This means no USB connectivity (this could be however accomplished using a USB-Serial breakout board).

Use an ATMEGA168, a 1kΩ resistor, a button, two 22pF Capacitor, two 10µF Capacitor, 5V Voltage Regulator, and a 16MHz clock crystal. You could program the chip with a USB-Serial breakout board or you could program the chip with an Arduino board and then pop it in the circuit. The power source should be at least 7 volts (we don't have that part yet).

Sorry, but this was a very messy schematics... Your should update it! Some parts should be definitely updated!:)

if you can't download, just create a file named name.fz and then open it in Notepad. Then past in it the Script you found clicking the downloads. So you save and drag and drop it in Fritzing. Fritzing then will ask you to convert the components and the Project in a .fzz file.
