Im presenting some of my own tested schematics. You can choose one of four categories just by clicking of the corespondent picture. The components I used, are usually not so hard to procure. Id tried to keep my work as close as possible to the industrial standards.
Audio Schematics:
This section is about preamplifiers, medium power amplifiers, power amplifiers, ton corectors, equlizers, VU-meters, and others.
It is presented the entire audio chain, from audio input (a small aparatus output: walkman, pick-up, cd-player) to speakers. It contains also a speakers protections module.
Step by Step
motor schematics:
This section explain how to controll a Step by step motor directly from a personal computer. You can also, with small modifications, a dc-motor controlling. It pay attention to the computer port protection.
Power electrical
motors schematic:
This section present a few conection possibilities for the high power electrical motors and generators, high power converters. The schematics are only symbolic, without any real values.
All kind of 
other schematics:
This section is about all kind of electronical circuits. You can find here the small domestic automats, light solution for house and parties, detectors, laboratory application.
