I just updated the Accelerometer Based Mouse post with a video Bernard sent in. This is an awesome video of him playing a first person shooter game called Dark Messiah. In the video he is moving about and fighting while we watch both his monitor and the mouse. The video is embedded at the bottom […]

Bernard shows us how to use an use an accelerometer as a mouse. This project uses a MEMS X/Y accelerometer, a PIC microcontroller and a old mouse. He also describes a trick for powering the new mouse with the unused RS232 serial control lines.

The Maker Fair is in Austin this weekend! If you are in Austin or nearby you should not miss the fantastic event. Take a look at the schedule of events here. My biggest problem is how to see everything.
I will be there to help Paul Badger of Modern Device Company. Drop by the Make Store […]

Frank shows us how to made a PIC based logic probe. He covers everything with step by step instructions and explains the how and why. This article is a great kick start for the PIC microcontroller, Frank really does cover the basics well. Including what software to get, how to set it up, how to […]

Sean shows us how to use an Arduino for kegerator temperature control. A Kegerator is a beer keg built inside a refrigerator. Anyone want a cold beer? He discusses the home brewing process and how a microcontroller can be applied to this and many other sensing and control task. Man I’m thirsty now…
