Repairing things is one of the best reasons to get a 3D printer, and it might just give you the push you need to learn to model items for yourself. If you’re looking for some inspiration, here are some examples of how a 3D printer can come in clutch and save you money.

The ESP32 microcontroller has become hugely popular in the worlds of DIY electronics and smart home automation. You can use the small chips to build an enormous range of different things at relatively low prices. One of the biggest barriers for people dipping their toes into the world of ESP32 is the fear of having to get stuck in with a soldering iron, but there are plenty of genius ESP32 projects that don't require any soldering at all.

Hulu's July lineup might even be more impressive than last month, which included the fifth and final season of The Bear. July's offerings include splashy premieres and anticipated returns. Kicking things off is the sequel to an underrated 2019 horror comedy that I thoroughly enjoyed.

Welcome to your guide to Pips, the latest game in the New York Times catalogue.

Released in August 2025, Pips puts a unique spin on dominoes, creating a fun single-player experience that could become your next daily gaming habit.

Currently, if you're stuck, the game only offers to reveal the entire puzzle, forcing you to move on to the next difficulty level and start over. However, we have you covered! Below are piecemeal answers that will serve as hints so that you can find your way through each difficulty level.

How to play Pips

If you've ever played dominoes, you'll have a passing familiarity with how Pips is played. As we've shared in our previous hints stories for Pips, the tiles, like dominoes, are placed vertically or horizontally and connect with each other. The main difference between a traditional game of dominoes and Pips is the color-coded conditions you have to address. The touching tiles don't necessarily have to match.

The conditions you have to meet are specific to the color-coded spaces. For example, if it provides a single number, every side of a tile in that space must add up to the number provided. It is possible — and common — for only half a tile to be within a color-coded space.

Here are common examples you'll run into across the difficulty levels:

• Number: All the pips in this space must add up to the number.

• Equal: Every domino half in this space must be the same number of pips.

• Not Equal: Every domino half in this space must have a completely different number of pips.

• Less than: Every domino half in this space must add up to less than the number.

• Greater than: Every domino half in this space must add up to more than the number.

If an area does not have any color coding, it means there are no conditions on the portions of dominoes within those spaces.

Building a smart home can feel like an expensive process. There are plenty of excellent smart home devices that come with price tags to match. You don't have to spend a lot to build a great smart home; there are some excellent devices that are relatively cheap.

I hate it when the internet goes down, or I can't get cell reception. We tend to take it for granted that we have access to insane amounts of information from our phones, and only appreciate it when it's gone. I wanted to create something that would let me access some of that information even when I was offline, so I decided to turn my old Kindle into a Wikipedia archive.

Google Maps is one of the best ways to get around because of how it adapts. Things like traffic and construction zones are taken into account, but so is fuel efficiency. However, it’s not a one-size-fits-all setting, and you probably haven’t touched it.

Smart speakers come in all shapes, sizes, and price points—you can even make your own. But before you put one in your home (or another one), there are a few important questions you should ponder.

Netflix is packed with something for everyone year-round, but its collection of summer shows and movies is incredible. Whether it's a light romance or a seasonal adventure, your summer watch list this year can be filled with the hottest titles.

Once, my homelab was a simple setup. I had an old PC stuffed into a corner of my basement with a few Raspberry Pis haphazardly scattered on the top of the case. However, as my setup has grown in usefulness and complexity, I had to seriously reevaluate how everything was configured so that it was consistently useful.

The Austrian GP offered another thrilling weekend of racing from the best drivers in the world. George Russell came out on top after holding off the advances of Verstappen and Antonelli. Ferrari and McLaren constantly swapped positions just behind in what was one of the most interesting GPs of the season.

Will we get more of the same from the British GP? We certainly hope so.

If you want to watch F1 2026 for free from anywhere in the world, we've got all the information you need.

When is the British GP?

The British GP is the ninth race of the 2026 F1 season. Here's the full schedule from Silverstone:

• Practice 1 — 7:30-8:30 a.m. ET on July 3

• Sprint Qualifying — 11:30 a.m. to 12:14 p.m. ET on July 3

• Sprint — 7-8 a.m. ET on July 4

• Qualifying — 11 a.m to 12 p.m. ET on July 4

• Race — 10 a.m. ET on July 5

Fans can follow all the action from this race weekend without spending anything.

How to watch the British GP for free

It's important to note that Channel 4 will be providing live coverage of the 2026 British Grand Prix for free in the UK. That's nice and easy for fans in the UK.

If you're based in the U.S., you'll need to take a few additional steps to watch this race weekend for free.

I subscribe to Amazon Prime. I subscribe for the fast shipping, exclusive Prime Day deals, and access to Prime Video. It's the access to Prime Video that becomes all-important for F1 fans.

It is now possible to sign up for a seven-day free trial of Apple TV+ through Prime Video Channels. F1 is exclusive to Apple TV in the U.S., so by accessing this free trial, you can watch select races for free this season. The subscription costs £9.99 per month after the trial ends, but you can cancel this renewal at any time. By cancelling ahead of the renewal, you can watch the British GP this weekend without spending anything.

I understand the argument that I'm not really watching for free because I subscribe to Amazon Prime. I get that, but Amazon Prime does offer a 30-day free trial period if you're new to the service. By signing up for this free trial and then gaining access to Apple TV through Prime Video Channels, you can truly watch select races for free this season.

If you've already used this hack to watch a race this season, there are some alternatives.

My recommendation is to go direct to Apple TV. This popular steaming service comes with a seven-day free trial for new subscribers. Alternatively, Apple One bundles Apple TV with Apple Music, Apple Arcade, Apple Fitness Plus, Apple News Plus, and 50GB of iCloud Storage for $19.95 per month after a one-month free trial.

The best Apple TV free-trial offer comes with purchases of new Apple devices. New subscribers can get three months of Apple TV for free after purchasing any eligible Apple product. If you're planning on buying something from Apple, you could gain access to Apple TV for a pretty large chunk of this season. You will obviously need to buy something, but if you were already in the market for an upgrade, this method makes a lot of sense.

This season of F1 is unlike any other. Every season of F1 has a number of fascinating storylines to follow, but due to a major set of regulation changes, there's so much uncertainty right now. And uncertainty can lead to exciting racing.

Lando Norris secured an incredible title victory on the final day of last season. Now the pressure is on McLaren to defend that title against a long list of talented drivers and motivated teams. The likes of George Russell, Kimi Antonelli, and Lewis Hamilton are all challenging for race wins this season. Mercedes look like the team to beat this season, but Ferrari are not far behind.

If you are interested in watching F1 2026 for free from anywhere in the world, we've got all the information you need.

The midsize pickup manages to be popular and overlooked at the same time. In 2025, Toyota sold nearly 275,000 Tacomas in the U.S., even outselling the Corolla. Yet it is the full-size and heavy-duty trucks that often steal the headlines thanks to their staggering tow ratings and prodigious power outputs.

I've never understood the appeal of wall-mounted tablets for controlling a smart home. To me, dashboards have always felt like expensive replacements for physical switches. However, a recent project finally made me realize that wall-mounted control panels can have their place

Camera accessories are some of my favorite things to 3D print. Photography can be an expensive hobby, and one that rewards experimentation and creativity.

Installing programs on Linux is a fairly simple process. Using a package manager and an installation command ( sudo apt install [program name] for example) in your terminal installs an application, assuming it's available in your distro's repositories. As I grew more experienced with the operating system, I stopped installing Linux apps the traditional way, largely because the other options offer more control, variety, and customization.

Happy 4th of July, America. This year's Independence Day celebrations are a little extra special as we celebrate the United States of America's 250th birthday.

Across the country, many people will spend the day at the beach or at a barbecue, capping the night off with a fireworks display. But, if you're spending the night indoors, there are still plenty of ways to celebrate with an array of July 4th fireworks livestreams.

Macy’s 4th of July Fireworks 

Perhaps the most well-known of the Independence Day celebrations is the Macy's 4th of July fireworks. If you live in NYC, you can catch them live. Otherwise, you can tune into NBC or Peacock at 8 p.m. on July 4th to watch the show.

While the U.S. is celebrating its 250th, Macy’s 4th of July Fireworks is also celebrating a milestone with its 50th anniversary this year.

PBS's America Made in Virginia: 250 Years Together

While many of the livestream options on this list will require a paid subscription to a particular streaming platform, PBS is airing its 4th of July special on YouTube for absolutely free.

America Made in Virginia: 250 Years Together will start at 8 p.m. on July 4th and culminate in a fireworks and pyrotechnics display from Colonial Williamsburg.

Disney Celebrates America

Disney is also getting in on the 250th anniversary of the United States celebrations with its own event.

Disney+, Hulu, and the ESPN app will stream a 24-hour broadcast called "Disney Celebrates America" that checks in on 4th of July celebrations around the country, which will ostensibly include at least a few fireworks displays. The grand finale, Star-Spangled Bash in Nashville, will also be hosted by ABC and deliver one of the country's largest fireworks and drone shows.

The broadcast kicks off at 10 p.m. on Friday, July 3rd, with the main event out of Nashville starting at 8 p.m. on July 4th.

Freedom 250 fireworks display

There's been a lot of controversy surrounding President Donald Trump's own Freedom 250 group, set up to lead Trump's 250th anniversary celebrations. You've probably seen the memes about the lackluster attendance for Trump's Great American State Fair all week.

With that said, Freedom 250 is claiming they're about to have a record-breaking 40 minute long firework display on the 4th of July with more than 850,000 fireworks. And, according to the group, the MonumentCam atop the Washington Monument will be the premier free-to-watch livestream to watch it all.

The Great American Block Party 250

Paramount+ and CBS are hosting their own 3-hour Independence Day special at 8 p.m. on July 4th. 

Like Disney's, the show will check in on 4th of July celebrations and firework displays from around the country. The broadcast will also culminate in their own feed of Freedom 250's Washington, DC, fireworks display.

I test new robot vacuums on a regular basis and compare them to the top performers from previous months, with all my evaluations taking place in my own home on various rugs, tile, and hardwood floors. As I test each robot vacuum and tweak its settings for optimal performance, I keep notes on its overall suction power vigor, scrubbing efficacy (if it's a robot vacuum and mop combo), pet hair pickup, the convenience of its automatic emptying and self-washing mopping pads, accuracy of smart mapping and small obstacle avoidance, and the overall user experience. But the final boss here is cost efficiency — I'll be the first one to point out when a cheap robot vacuum actually works well for the price, or when a high-end robot vacuum is actually worth the splurge or not.

July 2026: I added the Narwal Flow 2 as the new pick for best roller mop robot vacuum overall, bumping the Roborock Qrevo Curv 2 Flow to the best roller mop robot vacuum under $1,000. The Narwal Flow 2 has stronger suction power and more advanced AI spill detection.

March 2026: I added the Roborock Qrevo Curv 2 Flow as the best roller mop robot vacuum, replacing the Dreame Aqua10 Ultra Roller. Though the Dreame has more powerful suction on paper, the Curv 2 Flow demonstrated better edge mopping and comparable vacuuming. I also replaced the Eufy X10 Pro Omni with the Eufy C28 and shifted it to my budget roller mop pick. The X10 Pro Omni is two years old at this point, and the new C28 offers more advanced cleaning and obstacle avoidance.

January 2026: I added the Dreame X60 Max Ultra Complete as the best robot vacuum right now and shifted the Aqua10 Ultra to the best roller mop robot vacuum. The Roborock Saros 10R, which was listed as the best option for corner cleaning, has been removed from the list. It costs nearly the same amount as the X60 Max Ultra Complete, which has near-identical corner mopping abilities and much stronger suction power.

December 2025: I added a disclaimer to the pick for best Roomba value in light of iRobot's bankruptcy news.

October 2025: I added the Dreame Aqua10 Ultra Roller as the best robot vacuum right now and shifted the Roborock Saros 10R (previously named the best robot vacuum right now) to the option for best corner cleaning.

July 2025: I removed the Shark Matrix Plus 2-in-1 robot vacuum from this guide. While it was a solid budget mopping robot vacuum for its first year or so on the market, it's now a little bit too basic compared to other newer budget robot vacuums.

A virtual reality experience that asks attendees to sign over their biometric data sounds like the start of an episode of Black Mirror. But it's actually the reality of the Black Mirror Experience, now open at The Shed in New York City.

SEE ALSO: Every 'Black Mirror' episode ever, ranked by overall dread

The experience guides you through the halls of Phaethon Labs, a futuristic company where you can build a digital clone of yourself called a LifeAgent. This AI clone is able to do all the unpleasant tasks you don't want to do, plus set you up for success when it comes to your life goals. All it and the Black Mirror Experience need from you are your name, your life goals, and your face and voice. You cannot participate in the experience without consenting to the use of your face and voice.

In a world where our personal data is sold and packaged on the daily, you may think, "What's one more consent form, right?" But for anyone who's seen Black Mirror, the idea of giving up your likeness is enough to raise red flags. (Or, if you're like me, it'll make you full-on queasy.) Plus, there is precedence for concern: Remember when Netflix used users' photos in billboard ads tied to "Joan is Awful"?

If you feel discomfort about giving up biometric data for a fun VR outing, staffers at the Black Mirror Experience will walk you through what the process actually entails. Your data is stored by UNIVRSE, the VR company behind the experience, for four weeks following your trip through Phaethon Labs. If you would like your data to be deleted earlier, there's an e-mail address you can reach out to. I did so, and the response to my request was speedy and helpful.

Once you get past the biometric data hurdle and strap on your VR headset, what's next? Attendees go through a "neural scan" to better understand what their LifeAgent can do for them. This involves playing mini games and telling Sigmund Freud about a recent dream. (Yes, really.) The latter sequence also involves AI-generated responses from Freud where he analyzes your response and cooks up an AI image of said dream.

After that, you finally meet your LifeAgent, a digital replica with your face and voice. The results brought back my nausea in full force. My LifeAgent was a postcard straight from the uncanny valley, one that prompted me to consider the AI technology behind it and how fast it has advanced over the past few years. I had signed up to have this version of me made, but we also live in a world where anyone can make AI deepfakes of anyone else, with examples ranging from viral memes to film and TV studios resurrecting deceased actors. (For its part, the Black Mirror Experience uses human performers. Karina Matas Piper voices Phaethon Labs founder Cody Winters, while James Phillips voices various characters. Elsewhere, Imanol Dieguez serves as the mocap actor.)

After the unsettling reveal of your LifeAgent, the rest of the Black Mirror Experience rings oddly hollow. Instead of truly interrogating the implications of AI deepfakes and concerns of privacy and misinformation, it launches you into a sci-fi action sequence. The VR environments here are impressive, especially a series of labyrinthine tunnels and a vast underground construction facility. However, none of this bombastic action feels in tune with the true spirit of Black Mirror, whose episodes most often build to devastating conclusions instead of rollicking shoot-outs.

The Black Mirror Experience doesn't let you sit in that dread long enough. It only briefly gestures out to the problems its AI LifeAgents could cause, ranging from alienation from simple human tasks to full-on identity theft. But then it turns around and revels in AI technology, even turning your AI-created LifeAgent into a souvenir video for you to remember this dystopian trip by. Staring at the eerie grin plastered over my AI self's face in my own souvenir video, I kept thinking of one of Black Mirror's most prescient reminders: If you give tech companies an inch, they'll take a mile.

The Black Mirror Experience is now at The Shed until Sept. 6.
