I Replaced My Laptop’s WiFi with Coral TPU – Here’s What Happened!

Published at : 18 Dec 2025

In this video, I take an 11-year-old Lenovo S210 Touch laptop that has been running 24/7 for the past four years and attempt to upgrade it with a Coral TPU by replacing the old WiFi card. Can this ancient laptop handle AI-powered object detection for home surveillance? Watch as I transform this laptop into a powerful AI-based NVR using Frigate for real-time object detection and automation. If you've got an old laptop lying around, this video might inspire you to give it a new life. Let’s see if the Coral TPU works and what kind of results we get!
