Editor's note: Richard Alan Wotiz started taking products apart when he was old enough to pick up a soldering iron. In 1991, he started his design consulting business, and his specializations were hardware and software for consumer products and children's toys. Richard passed away on May 30, 2012. The entire Circuit Cellar community benefitted from his work, and his many projects and articles will continue to inspire engineers for years to come.
