Hi all, I've been dropping in here on and off for a few weeks, and decided to register. I'm a Chem. Engineer working in the medical device industry, but I enjoy developing various circuits for use in my Halloween animatronics and props. They're pretty simple stuff - timers, motor controllers, various sensor circuits and the like. I also do some circuit development for custom and unique fixturing at my work. Anyway, I look forward to learning more about my hobby; I'm sure I'll be asking a few questions from time to time!
