![]() ![]() ![]() KIT OF PARTSTalking Electronics supplies a kit of parts that can be used to build the majority of the circuits in this book. 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. If you are starting in electronics, see the World's Simplest Circuit. Before you start, the home-made Speaker Transformer project and Transistor Tester are the first things you should look at. No matter what you do, I know you will be keen to hear some of the "noisy" circuits in operation. This way they can be re-used again and again. 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). The choice is up to you but the idea is to keep the cost to a minimum - so don't buy anything expensive. 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. All you have to do is identify the leads of an unknown device and you can build almost anything. Basically there are two types of transistor: PNP and NPN. 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. This has already been covered in TALKING ELECTRONICS Basic Electronics Course, and can be obtained on a CD for $10.00 (posted to anywhere in the world) See Talking Electronics website for more details: data is at the bottom of this page and a transistor tester circuit is also provided. 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 components. It's amazing what you can do with a few transistors and some connecting components. ![]()
