This $13 device saved me from buying a bunch of expensive smart bulbs

Sun, 11/30/2025 - 16:01

Smart lighting is the gateway drug of the smart home, but replacing all the bulbs in my home would be a non-starter. We just built our home, and the ceiling is filled with recessed lighting.

Why I refuse to buy a wireless keyboard with a built-in battery

Sun, 11/30/2025 - 15:30

All of my most recent wireless keyboards have built-in lithium batteries. At first, this seemed like a step-up, but it turns out that when we're talking about peripherals, there are plenty of reasons to prefer good old removable AA batteries.

Wall-mounted Home Assistant displays are cool, but you don’t need one

Sun, 11/30/2025 - 13:00

Why is everyone suddenly obsessed with wall-mounted dashboards and control panels in their smart homes? These displays can take the form of touchscreens with controls or E-Ink panels that just display information about your home. For most, the usefulness of such a project is severely limited.

Sun, 11/30/2025 - 12:00

The FORMULATEXT function is often dismissed because it merely transforms a formula into text. However, that raw text is exactly what makes it so valuable. So, stop thinking of it as a one-trick pony—it's the perfect tool for auditing, input control, and logic validation.

BitLocker is the most common way to encrypt your Windows PC to protect it against data theft in the event that someone steals your PC, but it isn't the only option. If your PC doesn't have BitLocker and you want something more fully-featured than Device Encryption, VeraCrypt is probably the tool for you.

4 New dark patterns added to Windows 11 in 2025

Sun, 11/30/2025 - 00:00

Another year, another long list of changes to Windows that "nudge" you into making choices or adopting behaviors that aren't in your interest. At some point, it really feels like Windows stopped existing to make the actual users of PCs happier, and now serve a different master. I think these changes are the most worrying.

Sat, 11/29/2025 - 22:25

Windows 11 users are getting a frustrating new bug that completely hides the password sign-in option on the lock screen, making it incredibly difficult to log into their PCs. This isn't a total lockout, but it's certainly a massive headache if you use a real password.

Why do some phones use these weird fast-charging USB cables?

Sat, 11/29/2025 - 22:00

For the longest time, smartphone battery life was a real issue. I remember my first few smartphones basically traveling with me from charger to charger. They would charge at my desk, charge in my car, and charge next to my couch. While phone battery life is now much better, the real revolution has come from fast-charging.

The weird world of Kindle page-turner remotes

Sat, 11/29/2025 - 21:00

So you buy a Kindle and you think to yourself, "I sure would like to turn the pages from way over here, surely there's a solution for that?" Well, to my personal surprise, I have recently learned both that people who want to turn eReader pages at a distance exist (it makes sense when you think about it) and that Kindles in particular have no elegant way of achieving this goal. Hence, the existence of weird and wacky "Kindle page turners."

Google and Amazon are particularly good at selling the smart home vision, but these platforms have some big drawbacks, too. Consider switching to or starting out with a more capable and reliable alternative, which will save you money and frustration in the long run.

Sat, 11/29/2025 - 19:30

I use all sorts of software when I travel: a VPN, streaming music apps, cloud storage, and more. I turned my Raspberry Pi into a one-stop-shop travel router that combines all of those uses into one device, so I don't have to worry about them individually on my phone, laptop, or console.
