Arduino Adventures – DC Buck Converters

My next electronic adventure is in the world of Arduino and the Atmel ATMega32 MPU . So I'm going to get the Arduino starter kit and work my way through the projects that come with it. Once I have a grasp of it. I'll solder up my own board for a project I've been hatching. 

So, first things first. I'll need to power my projects. Enter Buck Rogers.

Well,,,,,, no. Buck converters. I got a larger one with a display to power the breadboard phase. Once done I have some smaller ones to house with my projects.Linear voltage regulators would be cheaper but they have draw backs in efficiency and the amount of heat they dump.
 

 5.3V on the buck converter display but just 5V on the Fallout style Multimeter,

my digital one is dead.

The little guy on top will be gong into the project and then I'll keep the large one for the breadboard stuff.

Thinking about another console mod for my first AVR project. Control everything through an ATmega32, with a display and some mode selection buttons.

I got both the large and small  buck converters on Amazon for a fair price.
