I will discuss how to mount a transistor to a heatsink & assemble the circuit but won't get into soldering as some RGB LED strips come with leads (and there is no shortage of great tutorials out there).

Your author’s first project covered by Hackaday was for a meter created using an automotive gauge stepper motor. This isn’t the first custom meter we’ve seen on Hackaday. The software savvy will say it’s pretty easy to replicate, but the hardware-only hackers among us might need a bit of help. The data is then sent via USB-serial to the Arduino Mega. A bit of math converts this into pointer values and LED colors. Basically they are using a Rust program to call systemstat, obtaining the current CPU utilization data in Linux. The system is controlled by an Arduino Mega, with the meters driven using the PWM pins. The whole bank going red would sure get our attention! The LEDs allow a splash of color to draw attention to the current state of the machine. The RGB LED strip is positioned so two LEDs fit under each meter. Of course, the original milliamps legends wouldn’t do much good, so designed and printed graduations that glue over the top. The meters themselves are low-cost 5 mA devices. The monitor is built from 14 analog meters, along with some WS2812 RGB LEDs.Įach meter represents a core on ’s CPU, while the final two meters show memory and swap usage. Recently, they have created a hardware CPU monitor that displays how PCs are parallelizing compile tasks at a glance. Over at Computing: The Details loves to make fun projects.
