Base model of the solder exhaust fan near completion
This project was collaboratively developed by the Fall 2017 AC/DC Fundamentals class. Principles in this project provided an application of Ohm's Law and calculating voltage and current on a standard computer fan using a digital multimeter. The project introduced soldering, circuit design/schematic drawing, component selection, electronic product design, and iteration. This project became a regular tool in the lab used by these students and more to work on projects and safely solder in the lab space.
Life is better with less solder fumes. The exhaust fan in action...
