Ross Smith from the University of South Australia gave an interesting microcontroller design presentation that contains some useful information for anyone that is considering using one in their next project. “This presentation looks at how to develop your own custom microcontroller hardware from scratch. Often laptops and general purpose computers are too powerful and too large to use for simple hardware projects. Often you can perform tasks like controlling DC

This Lighter Accelerometer hack by Bardlund demonstrates piezoelectric properties. “Piezoelectricity is the ability of crystals and certain ceramic materials to generate a voltage in response to applied mechanical stress. Piezoelectricity was discovered by Pierre Curie and the word is derived from the Greek piezein, which means to squeeze or press. The piezoelectric effect is reversible in that piezoelectric crystals, when subjected to an externally applied voltage, can change shape by
