Download book 200 transistor circuits TALKING ELECTRONICS, This e-book contains 100 transistor circuits. The second part of this e-book will contain a further 100 circuits. 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 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.
It’s wonderful what you can do with a few transistors and some connecting components. And this is the place to start.
Most of the circuits are “stand-alone” and produce a result with as little as 5 components.
We have even provided a simple way to produce your own speaker transformer by winding turns on a piece of ferrite rod. Many components can be obtained from transistor radios, toys and other pieces of discarded equipment you will find all over the place. Transistor data is at the bottom of this page and a transistor tester circuit is also provided. There are numerous categories, and I am sure many of the circuits will be new to you because some of them have been designed recently by me.
Basically, there are two types of transistor: PNP and NPN.
All you have to do is identify the leads of an unknown device, and you can build almost anything.
You have a choice of building a circuit “in the air,” or using an experimenter board (solderless breadboard) or a matrix board or even a homemade printed circuit board. The choice is up to you but the idea is to keep the cost to a minimum – so don’t buy anything expensive.
If you take parts from old equipment, it will be best to solder them together “in the air” (as they will not be suitable for placing on a solderless breadboard as the leads will be bent and very short).
This way they can be re-used again and again.
No matter what you do, I know you will be keen to hear some “noisy” circuits in operation.
Before you start, the home-made Speaker Transformer project and Transistor Tester are the first things you should look at.
If you are starting in electronics, see the World’s Simplest Circuit. It shows how a transistor works, and three transistors in the 6 Million Gain project will detect microscopic levels of static electricity! You can look through the Index, but the names of the projects don’t give you a full description of what they do. You need to look at everything. And I am sure you will.
