5V Battery Powered Pocket Sized Variable Power Supply

The power supply presented here is Battery Powered, Variable and pocket Sized. It is portable and fully functional. You not have to now carry AA Sized Cells. I get frustrated when I need AA or AAA sized Batteries. At those times, this power supply is made for. It comes handy when you do not want a heavy duty power supply. This power Supply unit can be adjusted. You can adjust the output with the help of the DIP switches attached. I have used a sticker paper on a left out portion of PCB for showing output voltage information. The circuit is extremely simple. This can be beginner’s first ever power supply unit. You must know Basics Of Electronics and about resistors as they are the main things.”
