Are you on the fence between using your phone as a 3D scanner or buying a professional 3D scanner? I’ve always wanted a 3D scanner, but I also thought my phone would be just as good. I scanned the same object with both a professional 3D scanner and my iPhone 17 Pro and printed the results—and they were not what I expected.

It's Monday morning, and an "updated" copy of an Excel workbook is sitting in your inbox. But when you open it, it's often impossible to tell what's changed. Instead of playing a game of spot the difference, use these built-in Excel tools to highlight differences in seconds.

Narwal’s latest Flow 2 robot vacuum packs a lot of new features compared to its predecessor. With better suction performance, a higher-temperature mopping system with real-time self cleaning, and better navigation, the Flow 2 is a great upgrade to an already fantastic robot vacuum/mop.

There was a time when a luxury car was defined by the logo. Those lines have blurred today, as many mainstream manufacturers offer vehicles in their lineups with advanced powertrains, upscale interior layouts, and connectivity technologies that hold their own against luxury namesakes at a lower price.

When Android phones first took off over a decade ago, custom launchers were all the rage. The idea of completely transforming your phone’s look and feel was a huge draw for enthusiasts—and even non-techies. Today, however, launchers are almost unheard of. They’ve largely fallen out of favor in favor of whatever your phone came with, and frankly, I think that’s for the better.

When you buy a new smart TV, you expect a quality viewing experience as soon as you turn it on. Still, you may be accidentally accepting lower picture quality, unreliable connections, and privacy issues by keeping the default settings. The best performance gains are already inside the device you own. By following these steps, you can fix these distortions, stabilize streaming, stop the data tracking, and speed up your TV to what is now standard in the industry.

Your smart home hub won't last forever. It might be due to the hardware dying or becoming outdated, or because your smart home provider pulls the plug. Whatever the reason, you need to be prepared.

I consider myself part of many fandoms. Some are from my childhood, others from college, and now, as a young adult, but they all mean something to me on some level. One of those just happens to be Star Wars.

Just because your Android phone is starting to get old, it doesn't mean you have to replace it. There are things you can do to keep it running for longer. I recently decided to factory reset my old Pixel to try to freshen it up. Then, after I set it up again, I changed a few key settings. The result is that it feels almost as good as new.

When I was growing up in the '90s I always read about this mythical connection called FireWire. It was a connection mainly found on Macs, and I had never even seen a Mac in person until I was an adult, but long before then it had lost to USB decisively even on its home Macintosh turf. Or did it?

When Android phones first arrived, there wasn’t a built-in flashlight feature. So, flashlight apps were extremely popular—and profitable. One particular flashlight app got caught doing something not so bright, and the US government had to get involved.

True-crime documentaries are always a sure-fire hit on any streaming platform. 2025 saw the release of some doozies—beyond the usual SEO suspects, such as Chaos: The Manson Murders, American Murder: Gabby Petito, and The Fall of Diddy—that proved to us the true crime genre is moving in a direction that values education over exploitation.

I consider myself to be an expert procrastinator. Over the years, I've tried no shortage of tools and techniques to fix this problem. Pomodoro timers, distraction blockers, minimalist writing apps. Most of them are well-designed and do exactly what they claim. They help you track time and encourage focus. What they don’t do is enforce it.

The internet is global, but thanks to a complex set of pre-internet rules and legal agreements, there are virtual borders in place that restrict what you can see and do. Sometimes, it is also useful to appear as if you're accessing the net from a different location than you really are. In both cases, the preferred tool is a VPN or Virtual Private Network.

I experimented with Android Auto for a while, but I just wasn't terribly happy with its performance. Recently, however, all of that changed. I decided to give Android Auto another shot, and here are five ways it's improved since I last used it.

If you have a 3D printer sitting idle, it’s time to put it to work. Your PC gaming setup can be made so much better by printing instead of buying off-the-shelf parts. Here are five things that you should definitely 3D print before you ever consider buying.

Even having a super speedy fiber connection won't make you immune to various bottlenecks. The reality is that if you use the internet, you're bound to have some issues with it at one point or another. For many, this can lead to a long stretch of frustrating troubleshooting that ends in an annoyed phone call directed to your ISP.

For most people, the Linux terminal is where you troubleshoot issues or run sudo commands—not a place where you do your day-to-day work. I used to think the same way until I stumbled into the world of TUI (Terminal User Interface) apps—terminal-based tools with real interfaces. I tried a few, and while most didn’t stick, these five did. In fact, they’re so good they’ve replaced several graphical desktop apps I used before.

Being an avid reader on the modern internet sucks. After the disastrous pivot-to-video debacle of 2015 and experiencing the excessive amount of ads, pop-ups, consent forms, and overlays that plague modern websites, I yearn for the days of Google Reader and the simple RSS feed.
