List of Electronic Projects by Lewis Loflin
I've been a part-time adjunct professor at a local community college teaching electricity and electronics. My electronics website reflects what I've taught or been asked to look into by visitors. I have 40 years experience in electronics from vacuum tubes to modern solid state and industrial controls. In college I had a year each of physics, chemistry, and biology along with C, C++. Pascal, and assembly.
I taught myself the coding for Arduino, PICAXE, Raspberry Pi, Microchip PIC, Debian and Slackware Linux, CSS etc which I approach in a way to give my students a basis for their own projects. Every page on this website was hand-coded by me. My education philosophy is learn the basics, find working examples, then use what works as a foundation for further learning. Modify and try new ideas. I'd say my job title would be applied technologist.
