Ever wonder how to make an engine out of soda cans? Not even sure if it's possible? These videos will show you how to build a working Stirling engine out of cans and other general materials. Here it is in action:
If you've found your speakers to be lacking in the visuals department, this is just the mod for you. Using 3" PVC, you can turn your speakers into light-up glow rods that pulse to the beat of your music. You'll need some electrical skills and experience soldering to get this one together, but otherwise it's not all that complicated. The main components you are going to need are speaker drivers, PVC pipes, LEDs, and the necessary cabling for those devices. The device works best with higher vol...
Attaching files to an email is way more convenient than trying to link people to third-party file transfers. Unfortunately, the standard 25MB limit is far too small to send some files, like large videos or multiple audio files.
Making little robots with a LEGO Mindstorms NXT set is already cool, but putting one underwater? Now that's just crazy. That didn't stop this engineer, who built a LEGO submarine that can not only maneuver around his fish tank, but can also be remotely controlled with his Xbox controller. The craft has a sealed battery compartment, exposed Power Functions motors, and features real-time communication between it and a laptop using a NXTbee wireless module.
Here's an awesome weekend project that could leave you with a fearsome "Ping Pong Ball Mauler" capable of firing hundreds of balls a minute at your unsuspecting neighbors. Christian Reed built it out of a poly drum and a homemade pneumatic device. He turned a standard shop vacuum into a high volume, low pressure system that allows his contraption to continually fire a constant stream of ping pong balls at a rate of hundreds of balls a minute. Best of all, all of the parts he used can be bough...
Okay, it's not actually cake-powered, but it does use cake! Owing to the fact that cake and trapdoors are less than half a block tall, we can use fenceposts (which are a block and a half tall) attached to pistons to push people along, because the tops of the fenceposts will invisibly pop up through cake and trapdoors.
Getting angry makes you look weak, especially in an argument. Defuse your temper with these helpful tips.
This is no paper gun like you've ever seen before. Seriously. Tacome1942's homemade paper shotgun is a life-sized, fully functional Remington 870 replica. It would be hard to tell it apart from the real deal, not to mention it practically sounds like an authentic shotgun, too. The shotgun is made of approximately 97% paper, the remaining 3% consisting of pins, wires, and springs. Check out all the videos below to see the finer details, including the trigger group, shell stop, and disassembly ...
Thanks to modern "smart phones" and the internet, media by the people, for the people is finally a reality. Here's how to use your phone to be a mobile journalist.
Watch this video tutorial to learn how to calculate your carbon footprint. A carbon footprint is an equation that estimates just how much you, personally, are contributing to global warming—and all you have to do is plug some info into an online calculator. Figuring out how to make your footprint smaller, of course, is another matter.
NASA -- the National Aeronautics and Space Administration, the United States government's most infamous agency, the powerhouse of space exploration -- teaches you the basics of Isaac Newton's Laws of Motion. Who better to learn motion theory from than NASA?
There are more actions available for the Action button, but only a handful of iPhone models have that button. However, there is another button with new features you can use, and you can access all the fresh features on any iPhone model that can run iOS 18.
You can play background sounds on your iPhone to help you focus, stay calm, or fall asleep, giving you a personal sound machine wherever you go. Even better, there's a way to set each of your apps to play one of Apple's six ambient soundscapes automatically. When you open the app, its assigned sound plays, then it stops when you exit or switch to another app.
An unfortunate byproduct of Samsung's One UI version of Android is redundancy, where you have the Google/AOSP way of doing things mixed with Samsung's methods at the same time.
Though Microsoft has had trouble keeping up with the demand for HoloLens 2, the company has been able to supply modified headsets to the US Army.
Google Images, TinEye, and other reverse image search engines can help you find where images appear on the internet. You can discover what TV show or movie an image comes from, who took a photo, and if the profile picture of someone you're talking to online is really them, among many other uses. And there's a shortcut for iOS that makes running a reverse image search easy.
Unless you've been totally off the grid, there's a good chance you're aware that the Disney Plus streaming video service launched this week. And, if you're on this site, you're likely salivating over the new Star Wars series, The Mandalorian.
The prospect of loss or theft is something we constantly live with. Stolen iPhones fetch a premium price on the black market for parts like OLED display assemblies, frames, and charging ports. Making matters worse, if someone were to steal your phone, they could simply turn it off to avoid anti-theft features like Find My iPhone.
We public testers are in luck. Today, Apple released the second developer beta for iOS 13.2. As is the case with most beta releases, developers get theirs first, while public testers are left waiting. Will we get our update the same day, or will we need to wait? As it turns out, Apple decided to throw us a bone. The second public beta for iOS 13.2 is officially here.
The idea of squeezing your phone might have sounded a bit out there when it was new, but it's now a hallmark feature on Pixel devices. As useful as it is for summoning the Google Assistant, however, it certainly would be nice to be able pick and choose what action is triggered by squeezing the phone. Well, now you can.
Many apps, including Facebook, Twitter, and Facebook, do not let you download videos, even if they are living on your own account. Saving these videos usually requires a third-party app or screen recorder, which is inconvenient and can result in loss of quality. However, TikTok, the newish popular short-form video platform, makes it easy to download videos — even if they're not yours.
Until very recently, Apple apps were among the only ones that would play nicely with Siri on iPhones. If you wanted to take advantage of the digital assistant to, say, compose an email, you would need to go with Apple Mail instead of the email client you actually use. As of iOS 12, this is no longer the case.
Owners of Google Pixel devices now have a plethora of imaginary friends to play with thanks to the Playground augmented reality app.
In a world where augmented reality is becoming the hero of the movie marketing, Universal Studios has decided to use the technology to reinvent the traditional movie trailer, a time-tested tactic of film promotion, in support of the forthcoming Robert Zemeckis film, Welcome to Marwen.
Google subsidiary Owlchemy Labs has cooked up an experimental ARCore mobile app that enables smartphone users to follow along with their VR friends as they play games in a head-mounted display.
The latest sponsored augmented reality experience on Snapchat from a movie studio might be its scariest — and perhaps most popular — yet.
Accused of violating whistleblower and age discrimination laws by its security director, Magic Leap has taken an internal situation to the US District Court to clear its name of the allegations.
As we have seen previously with the likes of SethBling's Mar I/O videos and other examples, video games seem to be a great source for training AI neural networks. Augmented reality and machine learning are part of a collection of technologies that seem to be growing toward a point of maturity, and that will likely cause them to be intertwined for the foreseeable future. As developers, machine learning will definitely change the way we create software in the coming future. Instead of going lin...
By default, when you receive a FaceTime video call on your iPhone, the speakerphone kicks in immediately after answering unless you're wearing headphones. It's the exact opposite when it comes to FaceTime audio calls, but it's pretty easy to remedy if you'd rather have the speakerphone kick in instead of the built-in ear speaker.
Augmented reality headset maker DAQRI has collaborated with the US Navy to outfit the company's Smart Helmet device for use on battleships.
It seems to me you can't swing a dead cat near an augmented reality developer without hearing the word Vuforia escape their lips. PTC's software solution has become the go-to for most developers in the mobile AR space, and since they recently added full support for the HoloLens in Unity, I figured it was about time we learn to make something with it.
With smartphone makers ditching the headphone jack in the hopes of a truly wireless future, we're having to rely on Bluetooth devices like earbuds and headphones more and more. But the downside here is that these devices aren't physically connected to your phone in any way, which makes it way too easy to leave an important accessory behind.
With as much creativity and freedom that we have on Android, it feels a little underwhelming that the only gesture we can perform on the status bar is a downward swipe to expose the notification tray or quick settings. Maybe this is a field for Android to expand on in the future, but until that day, third-party developers are exploring this now.
Windows 10 is officially here, and frankly, there's a ton of new features in Microsoft's latest operating system. From the return of the Start menu to the new Edge browser, Windows 10 can take some getting used to.
The king of all Xposed modules is alive and kicking on Android Lollipop. GravityBox received an update over the weekend that will bring its bevy of UI tweaks to folks who have installed the framework on their Android 5.0+ devices.
Looking back at my childhood in the '90s, I can't help but feel like I was deceived. Movies that took place in the "future," like in the year 2015, would showcase awesome technology. You know, self-driving or flying cars, hoverboards, and virtual displays controlled with hand gestures—so where are they?!
Getting caught using your iPhone at school or work (when you're using it for personal reasons) can be a little bit embarrassing. Even worse, it can be detrimental to how you're perceived by your teacher or boss. But sometimes you just have to beat that next level of Candy Crush, view a risqué photo on Snapchat, or send an important WhatsApp message.
Google's Chrome Remote Desktop, which allows for remote access to your personal computer from your smartphone, has been out for almost a year now. Sadly, it's only been available for Android devices—until now. So, if you got an iPhone (or other iOS device), you can now access and control your computer directly from your smartphone or tablet just like with Android.
Navigating through the darkness—literal darkness, not the existential variety—is always a difficult task on its own, and my Android doesn't necessarily make it any easier. Many manufacturers offer quick access to a flashlight or torch feature, but my Galaxy S4 doesn't have an easily accessible toggle or button available to turn it on.
We all have apps that we use most frequently, or system preferences that we're regularly adjusting. Whether it's Netflix or a new game that you're hooked on, there are times when you want quick and easy access versus searching for them, even if they're on your home screen.
