I’m dreaming up a diy 12v bench power supply so I went and got myself a little 5a panel meter and a shunt.
I wanna see my panel meter working and get a feel for it.
I’ve used a panel volt meter before which was … educational for me.
That was just for an art piece to look vintage but it didn’t need to be accurate.
This time I want it for measurements, so I need to run some tests with a 0-5amp load.
My idea was to wire up a lot of ws2812 leds and turn them on one by one. My hope was that as I turned on more leds I would be able to raise the current draw.
I recon that would work but it seems overly complicated and I’m sure that’s not how it’s meant to be done. Typing in “testing my pannel meter” in a search engine just yeilds results for DMMs understandably.
What’s an example of a super simple setup I can use to get a feel of this panel amp meter?
I have so much electronic equipment now… surely I have something that’s easier than pulling out an arduino and programming addressable leds.
