Cancelled! Getting Started with Transistors


Electronics enthusiasts use transistors as switches and amplifiers in a wide range of applications. While they are relatively simple devices they are often a source of confusion and frustration when we are called upon to use them. NPN? PNP? MOSFET? JFET? Which of the 10,000 in the catalog is the right choice?

In this class Ray will discuss how the most common transistors work (NPN, PNP, FET) focusing primarily on bipolar (NPN & PNP) transistors used as switches. MOSFETs and using transistors as amplifiers will be briefly touched on. Finally we will look at some rules of thumb and guidelines for choosing a transistor for your next project.

Attendees should have a working understanding of voltage, current and resistance including Ohm’s law. If you’re a little rusty you may want to check out a few online videos as refreshers.

Attendees should bring pencil and paper for taking notes, nothing else is required.

All proceeds go to Knox Makers.

There will be a fee for this class of $19.96 for the general public, $14.96 for current Knox Makers members. There will be a 3 person minimum. If the class minimum is not reached by midnight two days before the event the class will be canceled and all tickets will be refunded.

Directions: Knox Makers parking and entrance is located in the fenced area around the back of the SPARK building.

Knox Makers is a place for the Knoxville area’s engineers, artists, hobbyists, innovators, educators and entrepreneurs to work and play. We are a technology and art collective dedicated to the promotion of creativity enabled and informed by science. Our lectures, workshops, and outreach programs inspire and educate both members and the general public. Our workshop provides members with both the space for large projects and the tools to complete them. We are a non-profit educational organization supported by member dues and staffed by volunteers.
