“This website features several hundred demonstrations, models and explanations of topics from high school physics. Most of the apparatus are homemade, produced in a woodshop with table- and jig-saws and a drill press. Detailed instructions are well-illustrated; projects mostly require common hardware store items.
“The website is especially aimed at young teachers who could develop a fine collection of durable apparatus for a quality, lifetime career. This website collection has served the author for over 50 years. Because designs are generally simple, construction is not difficult; if needed friends and relatives (and even students) can lend a hand. More than a few topics are good make-and-take projects. The content is free to copy and use, please take advantage, improve as desired, and share.”
