Follow and UpVote me on Steemit so you don't miss a single project schematic.
These are very easy schematics to follow if you know the symbols.
If you go as far as to build these projects people may think you to be a genius.
Don't tell them any different, they don't need to know.
Very simple schematic using an LM317 adjustable voltage chip commonly referred to as a Buck Converter. The thing that make it adjustable is the 10K potentiometer. Just add a meter to the output and you can dial up any voltage you need that's less than 12 volts. Power LED lights, battery fans, AM/FM Radio or any other small project you might have in mind.
what is D2 good for ?!?
