The Growing Importance of Control Theory for DIYers

Brian Douglas

Control system theory is a branch of engineering that handles how to manipulate a dynamical system’s inputs to change the behavior or outcome of the system to something that is desired. The concept is simple enough to understand. In fact, … Continue reading


Linux Home Automation

Neil Cherry

My first home automation (HA) project included an Atari 800XL, a Heathkit X10 interface, and the “Build the Home Run Control System” article series from Steve Ciarcia’s Circuit Cellar column (BYTE, 1985). I was forever hooked on HA. Eventually, I … Continue reading
