Almost every boy experiments at one time or another with electricty and electrical apparatus. This book is presented in a manner which can be readily understood, and wherein a boy can "do something". The author has tried to present matter from a boy's standpoint, and to show the young experimentor just what he can do with the tools and materials in his possession or not hard to obtain. There is no better education for any boy than to begin at the bottom of the ladder and climb the rungs of scientific knowledge, step by step. Mr. Morgan has not only told how to make the various motors, telegraphs, telephones, batteries, etc., but he has also explained the principles of electricity upon which they depend for their operation and how the same thing is accomplished in the everyday world. CONTENTS Magnents and Magnetism Static Electricity Static Electric Machines Voltaic Cells and Batteries Electro-Magnetism and Magnetic Induction Electrical Units Wires and Accessories Electrical Measuring Instruments Bells, Burglar Alarms and Annunciators Telegraphy Microphones and Telephones Induction Coils Transformers Wireless Telegraphy Radio Receiving Sets An Experimental "Wireless" Telephone Electric Motors Dynamos An Electric Railway Miniature Lighting Miscellaneous Electrical Apparatus Each Chapter above has many, many topics to its credit. For instance, if we take just the last Chapter, Miscellaneous Electrical Apparatus, you will find the following sub-topics: How electricity may be generated from heat How to make a reflectoscope How to reduce the 110v current so that it may be used for experimenting An induction motor A motor without brushes Alterning current power motors Electro-plating Electrolysis Copper-plating Nickel-plating How to make a rheostat A current Reverser or Pole-changing switch Reversing a small motor How to build a Tesla high-frequency coin High frequency currents How to make a Tesla coil Experiments with high frequency currents Photoelectric cells or electric eyes The photophone Selenium How to make a selenium cell How to oeprate a selenium cell Conclusion
So you can see that just one chapter alone has a wealth of information for dads and sons alike. Purchase this book for your little apprentice and do some "bonding" over a great book!
Geared toward the older boy, this book by Sherman R. Cook includes 33 projects with excellent teaching material and much boy interest. The projects show how to get satisfactory results in a short time. Great for class projects and science fairs! There are "how to do it" suggestions, bill of materials lists and all of the projects can be readily made in a shop which has the usual hand metalworking and a few woodworking tools. The projects have been made as simple as possible because of the short interest span of boys. You're sure to enjoy working on these "how to make" projects with your son or daughter!

From out of the pages of Mechanics & Electricity Magazine and Modern Electrics Magazine prior to 1914 comes a collection of articles on high voltage and high power machines. Here you get a major series of articles by Stanley Curtis revealing details of a Tesla coil you could build having a secondary 18" high and 5" in diameter. You get details on the coil, the condensors, power transformers, various spark gaps, and all kinds of unusual technology. Much of this, no doubt, ended up in Curtis's hard-to-find Tesla coil book that we once reprinted. Great illustrations. Other articles cover the construction of a Tesla coil with a secondary wound on a glass jar about 4" diameter about 9" long, how to build a high-frequency resonator, how to build an X-ray set (don't aim it at me!), and a series on building an induction coil that could give a 6" long spark. And that includes details on insulating the wire, building the spark gap, constructing a motor-driven mercury interrupter, and even building, if needed, a plunge battery with mercury, potassium bichromate, and sulphuric acid. And you get a number of short articles on high frequency electricity, building a miniature Tesla coil, a small carbon-arc furnace, a coil winding jig for secondaries, and a water rheostat.
