This means you can use ANY NPN transistor, such as 2N2222, BC108, 2N3704, BC337 and hundreds of others. We have labelled the NPN transistor as BC547. There are lots of categories and I am sure many of the circuits will be new to you, because some of them have been designed recently by me.īasically there are two types of transistor: PNP and NPN. Transistor data is at the bottom of this page and a transistor tester circuit is also provided. This has already been covered in TALKING ELECTRONICS Basic Electronics Course, and can be obtained on a (mailto: send details of how I can pay for the CD) (posted to anywhere in the world) See Talking Electronics website for more details: To save space we have not provided lengthy explanations of how the circuits work. Many components can be obtained from transistor radios, toys and other pieces of discarded equipment you will find all over the place. We have even provided a simple way to produce your own speaker transformer by winding turns on a piece of ferrite rod. Most of the circuits are “stand-alone” and produce a result with as little as 5 parts.

It’s amazing what you can do with a few transistors and some additional components.

The idea of this book is to get you into the fun of putting things together and there’s nothing more rewarding than seeing something work. Most of them can be made with components from your “junk box” and hopefully you can put them together in less than an hour. The second part of this e-book will contain a further 100 circuits. This e-book contains 100 transistor circuits.
