Regulated Power Supply UPDATE

Finally I was able to find cheap panel voltage meter, which I can use for new version of my LM317 regulated voltage supply.

Few months ago I made LM317 voltage regulator, but it has no display to show you actual voltage. Only way how to determine actual voltage on old version is to make scale, but that is not reliable. So I’ve decided to take the old circuit put it into new project box and add this display. Now it finally looks like a power supply and I can be sure that I know what I’m getting on the output.


  1. Hello,

    Thank you very much for your ideas to post comments. Power supply is great for powering all kinds of electronic projects. It produces a well filtered, variable volts and easy to build and the parts are realitively easy to find...
