Easy electronic projects

Easy electronic projects 1

Hello friends,
I have been hearing from friends that needs to build a simple electronic projects and cheap. Which I also like them,and collect these basic projects in : Mini Projects and Cool Projects

The electronics Projects work surely. Because I know that you need to have great experience in Electronics.

But in these Categories have many projects,sometimes you may find the project you want is difficult.
Therefore, so I post this article to collect a projects list to easy to find circuit that you need.

The example below….
Note: However because I update this article manually so slow update.
You should see in Mini Projects and Cool Projects and Simple Circuits better.

Power Amplifiers with PCB
