To build self electronic apparatus can be given out of many perspectives: You can save money, you can design the units after own wish, but above all it is fun. Electronic building is not a new hobby. Ever since the start of the magazine Populär Radio 1929 to the current days of Radio & Television has the electronic buildings just been an appreciated and therefore a constantly recurring part. We have in the fifth of Radio & Television's books in the Build self-series collected some of the best of the build instructions from the years 1974 to 1979.
The electronics is been used today in enormously many areas. For that reason specialize oneself often who is building with electronic. Here we have collected instructions within some specialize area as measure instrument, radio control, amateur radio, car electronic, photo electronic in separately chapter. Furthermore you find a generally chapter there such constructions as e.g. burglar alarm and a digital thermometer is included. Various degree of difficulty is represented. So are e.g. instructions for both easy build measure instrument and advanced constructions as a seven canals radio control and a synthesis controlled transceiver for 2 m amateur band.
This is my hope that you shall find buildings that will be suitable for yours interests just, your knowledge and your economy.
Heat up the soldering-iron and tackle the projects!
Good luck!

Unfortunately, I can not publish the radio transmitter etc, only the
pulse-controlled glow plug driver, because of you can not buy the
toroidal core Arnold, transmitter antenna CLC, MF-filter Toko 4100 (yellow) and 4101 (white) and 4102 (black), etc. any longer from Transfunk.
Also, I will not publish or on another way distribute or copy the build projects on the
other sides.
I suggest that you take contact with the constructor or the library.

diagrams then this. No idea
about where to find more. Write down to get a grasp of the function... but
