The last item, the addition of a battery-powered lawn mower to the charging circuit, was the easiest part to accomplish. I went online and bought Sears' best battery-powered electric lawn mower. I ran an extension cord from the inverter to the transformer cube that powers the mower's battery charger. Once charging was complete, it was time to try the mower out on the grass. The unit mowed my entire lawn without a problem, and it was easier to maneuver around the lawn than my old gas mower. It...

Most people in suburbia are grid connected and content. They would like to do something with solar electricity, but really don't know where to begin. I found myself in a similar position. I loved the idea of going solar, but wasn't ready to make a large investment. Instead, I decided to start small and take my wife's home office off the grid. I also decided that I wanted to do the work myself. With these ideas as a starting point, I designed a small, stand-alone solar-electric system. I wanted...

In The Classroom
Over the years, things have changed in high school shop classes. The days of squaring up a board by hand with a jack plane are over. Today, these classes are called technology classes, and they had better be interesting which means being high tech, hands on, and light on theory. Although we still are required to teach specific shop skills, these skills are taught by using practical applications. At Darlington High School in Wisconsin, where I teach in the technology lab, we believe that the...
