If your vehicle has triggered a check engine light with fault codes P2024, P2025, or P2026, do not rush out to buy a replacement part just yet. While OBD-II scanners point directly toward an EVAP system failure or temperature sensor issue, the actual root cause is very often an unseen broken wire in the harness.
When I bought my 2006 Volvo XC90 back in April 2024 with 251,000 miles (now sitting strong at over 266,000 miles as of September 2026!), one of the very first things I wanted to do was upgrade the ancient factory head unit.
Like most people raised outside of Japan, the concept of an electronic bidet toilet seat sounded pretty weird to me at first. I’d heard about them and seen them popped into pop culture—like in Cars 2 when Mater gets completely startled by a high-tech Japanese toilet—but I never actually considered getting one for my own home.
Nearly sixteen years ago, I was a brand-new homeowner who knew surprisingly little about maintaining a house. Major home systems intimidated me, and our natural gas furnace sat right at the top of that list. When our heating system began failing in the dead of winter—about three years after we moved in—it didn’t feel like a routine home repair. To make the stakes impossibly high, we had just brought home a newborn baby. With an infant in the crib, every cold draft felt urgent, and every mechanical malfunction felt dangerous.
My son recently dove headfirst into the world of PC building. After weeks of research, part selection, and careful assembly, his new machine finally powered on — success. At the heart of it sat an ASUS Prime B550M-A WiFi II motherboard, packed with modern features like PCIe 4.0 and Wi-Fi 6.
Why this post exists
Homeowners are often told that any cracked heat exchanger is an immediate life-safety emergency that requires instant furnace replacement. This message is usually delivered with alarming language, unclear camera images, and very little explanation of how furnaces actually work.
This article is not arguing that cracked heat exchangers are harmless or should be ignored. Instead, it explains why continuous carbon monoxide (CO) monitoring can be a more practical, objective, cost-effective and homeowner-friendly safety strategy than routine, speculative heat-exchanger inspections — especially in modern homes with modern furnaces. The goal is simple: focus on real risk, not fear.
Fifteen years ago, I bought my first home. Like most buyers, I relied on the professional home inspection, which included a radon test. It was summer, and the results came back at 2 pCi/L—well under the EPA action limit. I was told the house was safe, and for most people, that would have been the end of the story.
Pi-hole is a powerful network-level ad blocker that acts as a "sinkhole"—a black hole for advertisements and trackers. Instead of letting those ads reach your devices, the Pi-hole swallows them whole, protecting every phone, laptop, and smart TV in your house. It is a fantastic tool, and there is an excellent hardware and installation tutorial over at the official Raspberry Pi site that covers the "how-to" perfectly.
However, do not finish your setup until you read this. Most tutorials give "textbook" advice that works in a lab but fails in a family home. If you follow the default settings in most guides, you will very likely find yourself unable to use the internet at all. The software will be running and the lights will be on, but your devices will be stranded. Make sure to come back to this post after you've followed the basic install steps to fix these two traps.

In 2024, I decided to give my 2006 Volvo XC90 (currently pushing 262k miles!) a much-needed audio system upgrade. My goal was to install a modern Android head unit to gain features like Android Auto, Apple CarPlay, and dedicated inputs for a backup camera and dashcam.
The main installation went smoothly, with one small exception: the radio antenna connection.
The head unit didn't come with a radio antenna. I purchased this antenna adapter from Amazon. But there was a problem. The head unit's chassis didn't have enough clearance to accept the antenna plug, so a modification was necessary.
