Finally done!

A project log for STM32 Open Source Multimeter

A multimeter, based on the STM32F373, which can measure voltage, current and power (both bipolar and DC or true RMS with multiple ranges).

I have finally arrived at the point where this project fulfills all goals I have given it. I'll release the source files along with an article (summarizing all functions, old and new) soon, hopefully before the end of this week. But before that, here's just a little teaser of the finished DMM:

This thing certainly looks fantastic!
I also love that it's a fairly cheap but pretty damn powerful device for this kind of measuring - plus, the USB interface means DIY logging, so who doesn't love that?
Love the buttons and casing, BTW :>

I actually made something similar with my DSKorder, but it's more for digital signal processing rather than voltage/current.

Too bad this didn't use the ESP PICO, otherwise you could've added WiFi connectivity. Still, this seems like a really fun project <3
