Projects and Circuits

Projects & Circuits is a compilation of selected construction projects appearing in Electronic Enthusiasts issues. Since copies of old issues of Electronic Enthusiasts have already run out, we decided to come out with Projects & Circuits. 
Most of these projects are presented in how-to-do format with detailed circuit operation, construction procedure, and necessary illustrations. The approach is synonymous with an assembly manual. Steps have been taken to simplify construction work and avoid possible confusion.

 

Available Projects & Circuits Volume

All reasonable precautions are considered in the preparation of the circuits and diagrams to ensure the reliability of the magazine. However, we cannot accept legal responsibility for it. Technical errors that escaped detection during publication and discovered later are immediately corrected and printed in the ERRATA section of the forthcoming issue and subsequent reprints.
