Engineering Projects For You

Free electronics projects, circuit diagrams and software codes available for students and hobbyists. Complete instructions on DIY electronic devices also available. These projects have been tested by EFY and are available with source codes. These are helpful with understanding concepts of electronics including basic components. The projects are designed to be helpful for engineering students and professionals building their own designs and circuits. The projects are also compiled from time to time to provide a single destination for project junkies. Let us know how you feel about the content and any thing you would like us to cover in the future. We hope you enjoy the content on this page!
