Some kits do require you to wind your own coils or trim off a lot of excess plastic which can be time-consuming.īefore we assemble the base components, we need to make up the electrical circuit. There isn’t anything you need to modify or change during the build, you can even use one which is preassembled if you’ve got one you’ve already built.ĭepending on your kit, it should take around half an hour to an hour to assemble. Theses Arc Reactor kits have been around for a couple of years and most of them are reasonably good quality, so you shouldn’t have any trouble following the enclosed instructions and assembling your reactor. We’ll start by assembling the Arc Reactor (with is done according to the enclosed instructions), then solder the electronics, then assemble the base and finally upload the sketch and run the Python script. I’ve split the build process up into a couple of steps to make it easier to follow. How To Build Your Own Arc Reactor CPU Performance Monitor They’ve become a lot more affordable and really expand your workshop capabilities. If you don’t have a 3D printer and you enjoy DIY projects and building things, you should really consider getting one. You’ll also need to 3D print the components for the stand. 1 x M5 x 8mm Hex Head Screws – Buy Here.4 x M4 x 8mm Hex Head Screws – Buy Here.4 x M3 x 8mm Hex Head Screws – Buy Here.Current Limiting Resistor (500 ohm) – Buy Here.What You Need To Build Your Performance Monitor Here’s a video of the build and the Arc Reactor in use, read on for the full step by step instructions as well as the code and print file downloads. The device doesn’t need any external power, it is powered by the USB port as well. On the computer’s side, a python script reads the CPU performance data from a Hardware Monitoring application and posts this data to the Arduino through a serial communication port. The arc reactor LED and OLED display are powered by an Arduino Uno in the base, which receives updates on the computers CPU usage every two and a half seconds and adjusts the pulse duration accordingly. This lead me to my computers CPU performance and I then decided to add the OLED display for a more accurate readout as well. I initially thought about using an Arduino to make the LED pulse as some sort of readout or indication. I started out by assembling an Arc Reactor kit, which has a built-in USB powered LED light and that got me thinking of a way to turn it into something useful for my desk. It plugs into one of your computers 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. 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.
