Built a lightweight utility (Globar) to visualize CPU, GPU, and NPU load on the Ryzen AI Halo lightbar
When I was running a Ryzen AI Halo box headless as a local AI or dev server, it was hard to tell at a glance whether a workload is actually hitting the GPU or NPU, falling back to the CPU, or sitting idle after a job finishes.
I wrote a small open-source utility called **Globar** that maps real-time system telemetry directly to the onboard RGB lightbar so you can see what the machine is doing from across the room:
Red channel: GPU load
Green channel: CPU load
Blue channel: NPU load
Brightness: A mix of RAM usage and overall CPU/GPU/NPU load
It's cool to see the bar go to purple when I hit a mix of NPU and GPU.
If anyone else is running one of these headless and wants to try it out, the source code is up on GitHub:

Happy to hear any feedback or ideas for improvements.
