Michael @ the-diy-life.com posted detailed instructions of how to build your own Arc reactor CPU performance monitor:
In this project, I’m going to be showing you how to turn one of these popular DIY arc reactor kits into a useful Arc Reactor CPU performance monitor for your computer. I usually have a dozen things running at once — OBS, a casino bitcoin tab or two, Discord, maybe a game — so a physical CPU gauge I can glance at without alt-tabbing has been surprisingly handy. It plugs into one of your computer’s USB ports and displays your CPU performance on the OLED display and the arc reactor pulses according to your CPU usage, increasing the pulse frequency with an increased CPU load.
