I turned a Raspberry Pi Zero 2W and an OV5647 camera into a Wi-Fi security camera with a Flask live feed, OpenCV motion detection, MP4 recording, and Google Drive uploads. The original project was straightforward—the fun part was updating it for modern Raspberry Pi OS, PEP 668, Picamera2, Python virtual environments, and current Google OAuth.
One innocent question, twelve terminal windows, an old Dell with a new job, and somehow cow ghee. A look at what happens when “I’m just going to check one thing” turns into another completely unnecessary adventure.
A modern take on one of my early DIY projects: turning an old laptop into a digital picture frame. See how the original build worked, what I learned along the way, and how a Raspberry Pi makes the same project smaller, cleaner, and easier to build today.
Learn how I deployed two Pi-hole servers to provide redundant DNS filtering, network-wide ad blocking, and improved reliability for my home lab. This project covers the design, benefits, and lessons learned from running a highly available Pi-hole environment.
This project transforms a Raspberry Pi Zero into a dedicated Google Calendar display using Raspberry Pi OS (32-bit Desktop). Since the desktop environment is included, only Chromium and a few configuration changes were needed to automatically launch Google Calendar in kiosk mode at startup. What I Configured Result When powered on, the Raspberry Pi boots…
