Welcome to our Website! We are here to show You how to make various interesting electronic devices on your own. Some of the devices are: Amplifiers, Power sources, Metal detectors, Alarms, Insect repellant, light, sound or touch sensitive devices, Whistle responder which produces sound when called by a whistle and our visitor's favorite Light and LED devices… We can’t name them all right here, so we suggest You browse through our collection of diagrams on your own.
We have over 400 free electrical diagrams, divided into 10 categories. You can check out the list of categories here, or in the main menu on the right. By entering one of the categories, You will see a list of circuit diagrams with a brief description.
You won’t need too much of an experience, for making most of devices offered here, but it’s necessary to know how to work with a soldering iron, know the circuit symbols and also correct reading of the electrical diagrams.
We have to mention that some of the diagrams use voltages that can be hazardous to health and your life, so we urge You to read the disclaimer before making any of the devices from our website.
We hope You will have fun, and also learn something while making devices using information from this website. Thanks for visiting!
