This book describes how to build a number of electronic projects which you can use with your Spectrum, ZX81 or Jupiter Ace microcomputers.
The projects include a Pulse Detector, Picture Digitiser, Five-key Pad, Model Controller, Bleeper, Lamp Flasher, Light Pen, Magnetic catch, Lap Sensor, Photo-flash, Games Control and six more projects that make up a Weather Station.
All the projects are fairly simple and inexpensive to construct. The most complicated part, the Address Decoder, is constructed as a separate item that can then be used with any of the projects.
Once built, the projects are easy to operate and a simple program or two is included to get you started. Of course, those readers who are more experienced at programming can have a lot of fun in writing elaborate programs for these projects, but the beginner can start with a short program and perhaps add extra features later.
