I spent 35 years as a technical high school teacher and technical director at Ancaster HS Ontario. I taught electronics, and introduced Auto Cad. I got rid of light bulbs in series and parallel and introduced grade nine students on how to make circuit boards. I created a course to interest female students based on videography which is still being taught today after being retired for 26 years! I’ve recently purchased a C-beam CNC and enjoy it very much. I am a Amateur radio enthusiast & like building PC boards on my CNC to get away from chemicals. However, I’m hooked on Inventables and have a few items on the projects page.
