An Introduction to light in electronics

Taken for granted by us all perhaps, yet this book could not be read without it, light plays such an impressive role in daily life that we may be tempted to consider just how much we understand. We most certainly appreciate its existance and although it has been around for a long time and now is the subject of much research, there is further to go if all the ifs and buts are to be eradicated.
Here it can only be claimed that the book makes a start (and we hope, a good one) into a fascinating and enlightening subject. It might be felt that such a study is going to involve us in much mathematical manipulation. Not so, for here nothing more than basic mathematics is employed. The book has been written with the general electronics enthusiast in mind, not the expert although many of these dedicated people may enjoy some light refreshment.

Electronic Projects for the Garden (Out of Stock)

Although library shelves and bookstalls bulge with gardening books, surprisingly few pages are devoted to electricity and electronics. It's no secret that success in the garden is largely dependent on the elements; keeping a weather eye open is important. You can't control the elements, but you can use them to control your results.
This book offers simple circuits that will monitor weather and environmental conditions and provide warnings or take remedial action as necessary. For example, such projects include rain detection, frost warning, temperature monitoring, dusk/dawn switching and automatic plant watering. You will find such interests as security devices process timing, warning cables, ponds and pumps, and low-voltage circuits for lighting schemes.To encourage beginners branching out in electronics, some construction methods are introduced. In the interest of safety, all projects are powered by low-voltage supplies.By: R. Bebbington, 160 pgs, 7 X 4.4”.(BP367)

Practical Fibre-Optic Projects

While fibre-optic cables may have potential advantages over ordinary electric cables, for the electronics enthusiast it is their novelty value that makes them worthy of exploration. Fibre-optic cables provide an innovative alternative to electric cables and represent a practical approach to the problem. Although this subject has not been totally ignored in the electronics press, practical designs using fibre-optics have so far been a bit "thin on the ground". This book provides a number of tried and tested circuits for projects that utilize fibre-optic cables.
The projects include:- Simple audio links, F.M. audio links, P.W.M audio links, Simple d.c. links, P.W.M. d.c. links, P.W.M. motor speed control, RS232C data links, MIDI link, loop alarms, R.P.M. meter,
