When a Raspberry Pi Zero runs CPU-heavy Python continuously, it overheats, throttles, and becomes unstable. The RootSaid Fix is to keep the Pi as a Thin Client and offload heavy computation to AWS Lambda, so the Pi stays responsive while the cloud does the work. This article shows the exact prime-number test I ran on…
