These days more and more temperature sensor projects appear on the internet so the world must be in need of temperature sensors 
. Daniel got hi’s done and up on the blog. The project is based on the LM35 Precision Temperature Sensor and the Arduino. He also plans on building a temperature sensor with max/min + clock and LCD, he promisses to post it on the blog when its finished.

Keith published a new article regarding a rotary encoder, the little potentioemeters that can spin forever. The article is about a Led calculator that he planed building for a while, and since the circuit has a rotary encoder he gives you some info about rotary encoders.

The first step on the project is joystick control of a servo over a USB connection. The end result which will make the project complete would be a RC rover monitored and controlled with a laptop and joystick on a WiFi network. The first step is already finished and the author managed to control a servo with the joystick.
Another useful application for a LED dot matrix display, well useful for those who use twitter. The purpose of the project is simple, it scrolls your twitters on the led matrix, this way you don’t have to be in front of your computer to see what’s new. Source codes and info about building it is provided by the author. The matrix is controlled by an Arduino
