/diy/ - Do It Yourself

I currently have one of these analog meters on my laser cutter, I would like to swap it, or add to it a digital meter with at least 2 decimal points so I can read it more accurately for reproducible effects.

It has a single knob to control current and I just want a readout of what that current is exactly that the analog meter is running, a percentage, or whatever, just something that is actually a number I can set it to, to get the same strength on the next project.

any advice would be appreciated
