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 amazing what you can do with a few transistors and some additional components. And this is the place to start.
Most of the circuits are "stand-alone" and produce a result with as little as 5 parts.
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.
