Well, the name is a bit too big for a project as little as this, but I couldn’t think of anything better at that moment.

It is a little circuit you can use on your bread-board. Most microcontroller-projects run at 5V, but cheap power supplies lack this setting. So the first step in building a circuit on a bread-board is building the power supply. Over and over again.

This is not much fun, so I built this circuit to use it ‘en bloc’. After building it, I thought of inserting another diode to prevent wrong connection to the power supply. Too late for me, but you should put one in if you build one of these.

I created the label using Eagle, even if it is not derived from the circuit I used. Anyway: It’s in the downloadable package.

At first I didn’t want to release this to the public. But after finding a link to a similar project in the Make Magazine — it’s on Instructable, and a detailed step-by-step guide to a circuit like this at SparkFun I did.

I just can say: I did it before I saw the other articles. :-)

I suppose the idea is simple enough for anybody to have it…
