(WIP) "Probelt" Voltage Display

thingiverse

WIP - After owning this motherboard (ASUS Crosshair VII Hero) for a while now, I've discovered that it has a "Probelt" for taking live readings with a DMM when overclocking, and so on. It's a neat feature, but as an occasional overclocker, I'm not really using it to its full potential. Eventually, the idea of installing some mini voltmeters came up, which led me to find these ones on Amazon - they're the only ones that can read hundredths of volts when below 10-12V: https://www.amazon.com/gp/product/B07W8V7HHB/ref=ppx_od_dt_b_asin_title_s02?ie=UTF8&psc=1. Note that you'll need to get the 3-wire kind because you can't draw power from the probelt. However, I managed to connect all the PWR and GND wires together and ground it on the probelt, which allowed me to use only one black wire and five yellow wires going to the probelt, along with one red wire drawing power from a free molex connector in the case - all temporarily held in place with solid core wire. I wondered if I should keep the GNDs separate, but since these voltmeters use high-side measurement, it doesn't matter. The readings aren't extremely accurate, so this mod is mostly for aesthetic purposes. I'm still working on the mount, especially the back piece, which I haven't printed yet. I'm also thinking about adding a power switch and exploring other mounting ideas. I have no idea how many motherboards come with a "Probelt" or something similar, but I thought I'd post it anyway. If you have something like this on your motherboard, let me know - maybe we can create a more universal mount or even design one custom for you.
