This is cool robot project by Nicola. He build Self-Balancing Robot which can stand without fall. He use Arduino Diecimila as main processor. For the sensord the robot project use Sparkfun IMU Combo Board - 2 DOF - ADXL203/ADXRS401.

This is a combo Gyro/2-axis-acelerometer. Of the many combinations avaiable, i’ve choosen the one with smaller range but better precision, as i think it’s more important in fine balancing. I’d like to have something that is stable and not swinging back and forth. (more…)

Do you want to modify your Espresso machine for low cost and more control? well, you can try what Nash Lincoln did. Modding the Gaggia Espresso with Adding a PID temperature controller and computer interface.

The goal of this project is to create a computer interface for my Gaggia Espresso machine replacing the factory thermal switches with a PID controller and the “steam” and “pump” toggle switches with a LCD/button menu system. This project use Arduino Decimillia micro-controller which utilizes the AVR AtMega168
