Oh Data, You so Awesome! We are going to use Node.JS to gather us some data. Given nodes plethora of well abstracted network abilities and it's deep evened nature, it will make quick work of plugging into various data sources and gathering / making good use of said data.
In this article, I'll show you how to make a simple touch-triggered switch. This is very useful for various electronic projects, from a simple bedside light to a flat panel touch keyboard. The circuit can vary in switching power depending on the transistors you use. For example, if you're looking into creating a 120V light that turns on when touched, you'd need two powerful transistors and an isolation relay. However, a simple flashlight that turns on when touched would only take a couple of ...
Joel Wulf with the Bremerton Fire Department discusses the right way to use a fire extinguisher. Fire extinguishers are safe and effective for use on small fires, but the entire contents are discharged in 10 to 15 seconds so you should never put yourself in danger by trying to use one to put out a large fire.
Giveaway Tuesdays has officially ended! But don't sweat it, WonderHowTo has another World that's taken its place. Every Tuesday, Phone Snap! invites you to show off your cell phone photography skills.
How many times have you been on the water and you've cast off a crankbait? You pick up the crankbait rod and make a cast, start your retrieve and your bait runs off to the side. Tuning will keep it straight. Wade Bourne, host of Wade's World on MyOutdoorTV, shows you how to tune up a crankbait.
No one fishes with a frog as lure, except when it comes to the non-living kind. This soft plastic frog bait is the perfect lure for bass fishing. They look lifelike, but won't make you feel like an awful fisherman. Watch as Wade Bourne of MyOutdoorTV shows you how to fish a plastic frog bait.
Airsoft doesn't get any better than a cloud chamber BB machine gun, aka Cloud BBMG. This design has an incredible rate of fire. If you've got a full charge of compressed air, it can easily fire more than 50 rounds per second at a 350 ft/s muzzle velocity. Since this is a legit airsoft build, it should be handled safely with the same care as any other airsoft firearm, and you should be wearing the same protective gear—protective mask, safety glasses, etc. My video details the build of this bea...
First, I would like to explain that among my family members, I am considered somewhat of an oddball. Mostly because of some of the mods that I have performed on a few of my woodworking tools. After I show you what I did to my drill press, you may be inclined to agree. When I first hatch an idea in my little pea brain, the first thing I take into consideration is whether or not this mod is irreversible and will destroy my tool. In the case of my drill press, I determined that it was safe to pr...
The worst can always happen. Even if you think you're absolutely prepared, you can somehow find yourself stranded in the middle of nowhere by yourself. It can happen. Without a map, without a compass, without a cell phone... without food and water.
In this article, I'll show you how to make a high-powered, long-range, air-powered rocket gun. This launcher is based on a sprinkler valve, a modified propane tank, and a few other components. Though not hard to make, this device is VERY dangerous! The rocket can seriously harm, if not kill any living thing it's shot at. Here's a video of it in action, quite an accurate shot by my friend Chris... Parts
Video games consoles have long wanted to be more than just consoles. Nintendo Japan called the NES the Famicom because they wanted to make it the sole family computer. Obviously that didn't work out, and most efforts to make consoles into all-in-one entertainment systems have had similar fates. Sony has done the best job with the Playstation consoles, probably because they have experience with other types of electronics that most video game companies do not.
Quitting a bad habit is not as straightforward as simply quitting cold turkey and getting it right the first time. So what to do if you really want to quit doing something that isn't good for you?
Tesla coils are totally insane, yet undeniably captivating. And they can be used for many things, from electric painting to dueling musical battles. But one trigger happy fellow has a different use for Tesla's lightning shooting coil. A weapon.
NASA reports that the sun erupted late last night with a large solar flare—an M8.7 class flare. The classification is calculated according to the peak flux of 100 to 800 picometer x-rays near Earth measured from the GEOS weather satellite. There are 5 letter classifications for solar flares, each with a linear 1-9 number scale of severity. M is the fourth most powerful class, with X leading the way. But last night's earth-directed coronal mass ejection (CME), captured by the Solar Dynamics Ob...
It is always a bittersweet moment to find yourself looking back on the fond memories that seem to have taken place in the distant past. When your favorite song from 10 years ago comes onto the radio, or when a sudden scent reminds you of the summers you spent as a child—these types of moments tend to trigger the fondest of memories. For this week's challenge, we'd like to see a photo that captures a nostalgic feeling, whether it be your favorite childhood food, meaningful memorabilia you've s...
If you didn't think you could make a high speed photography trigger or hack together some creepy googly eyeballs for Halloween, then you've got another think coming, because learning how to use Arduino just got easier thanks to Jody Culkin and her wonderful comic book introduction to the Arduino platform (and electronics projects in general).
Gamers who haven't already gotten tickets to PAX Prime, there is sad news. Three-day passes for the event are officially sold out, three full months before it starts. That is a Coachella-like ticket sale speed for such a large event.
It's more addictive than Angry Birds, perhaps as relaxing as transcendental meditation, and satisfyingly simpler than GarageBand. It's Otomata, a newly programmed generative sequencer designed by Batuhan Bozkurt, a Turkish sound artist, computer programmer, and performer. But really, it's best described as an audio/visual music toy that anybody can play online—with beautiful results.
WonderHowTo favorite NurdRage once again triggers the inner mad scientist in all of us (well, all of us WonderHowTo-ians at least). Below, watch what happens when steel wool- found in every common household Brillo Pad- is lit on fire.
About a decade ago, Deus Ex came out to rave reviews. Except this guy Tom Chick hated it. And said so, in a pretty blunt manner.
Attention all iPhone users. Engadget posts a helpful tip on possibly avoiding that painfully long iPhone 4 upgrade wait:
Sometimes ghetto is the way to go. Yankee ingenuity is always the way to go (at least on WonderHowTo, that is).
...his easy laugh and southern charm. Pull this trigger...it is just so electric. Not just the spark, but the 50,000 volts cursing through the tumid chamber, filled with liquid soluble polydimethalsiloxane.
Very cool project by Benjamin Gaulon. Gaulon has created a graffiti writing paintball robot, entitled PrintBall. He uses technology from (previously posted) EyeWriter to tag with his eyes, plastering a wall with paintballs.
On the surface, deleting conversations in Messages seems harder in iOS 13 after Apple removed the "Edit" button on the main page. Fortunately, they added a new gesture that lets you remove entire threads and individual messages with ease.
Are you trigger happy with a specific emoji with a particular friend? Do you like flinging emoji poo at a buddy who keeps acting sh*tty? We have good news. In the Facebook Lite Chat app, you can now set a specific quick access emoji for easy emoji spamming.
So, you undid something you typed on your iPhone. Maybe you used the new gesture in iOS 13 to do so. Maybe you shook your iPhone, on purpose or accidentally, to trigger the traditional undo method. Either way, you want your text back, or to redo your edit, and you aren't sure how to do it. Luckily, it's as easy as a swipe.
Most of us swipe on Tinder while on the go. With all the pictures, Tinder on Android and iOS uses a decent amount of data. If you know the pain of Tinder triggering overage fees, limit the data-hungry app. There's a little trick you can use to help keep your swiping up and your mobile bill down.
With the back button gone in Android 10, the new back gesture forced Google to change the way you access side navigation menus. The new angled swipe that you have to do to access the hamburger menu isn't the easiest, so you'll likely go back more times than you want. Well, there's an easier way.
If you're anything like most iPhone users, then you've probably grown tired of Siri's antics by now. She frequently has trouble with even the most basic of questions, and severely lags behind Google Assistant with regards to usability. Unfortunately, Google Assistant for iPhones has been less than ideal.
Spending time in a holographic environment brings the virtual world to life, but it doesn't actually create much interaction with your physical environment. So Daenet created a concept app called HoloTwin to demonstrate how holograms and real-world devices can interact with one another. While very simple, HoloTwin uses a holographic light bulb as a virtual switch for an actual, physical LED light. While you wouldn't want to strap on the HoloLens every time you wanted to adjust the lighting in...
Most new stereos come with an auxiliary port built in, but if you drive an older car, you're usually stuck with the radio or CD player, and we all know both of those options suck.
The great thing about security apps (other than the obvious) is that there is an abundance of them littered throughout the Google Play store. Cerberus, Got Ya!, Avast! Mobile Security, Norton Security & Antivirus, and Android Lost Free are just a few of the gems you can find in the plentiful sea of security apps for Android. Once in awhile, though, a new security application comes along that stands out from the rest, like AeGis.
It's hard to believe that a photo-sharing service could become as big as Instagram has. So big, in fact, that there are tons of websites, software, and products aimed at integrating it into our lives even more. Hell, you can even be Instagram for Halloween.
We all have that friend. You know, the one who can't resist posting pictures on Facebook of every single thing their newborn does. Babies are cute and all, but new parents don't seem to get that not everyone wants to see a play-by-play of every moment of their child's existence. For the rest of us, Unbaby.me is here to help. Unbaby.me is a Chrome extension that replaces baby photos in your News Feed with pictures of "awesome stuff." It's super easy to use. Just go to the homepage, click Add t...
According to Wikipedia, "Sympathetic Resonance is a harmonic phenomenon wherein a formerly passive string or vibratory body responds to external vibrations to which it has a harmonic likeness."

Metal is a great material to work with. It's rigid, tough, malleable and conductive, but sometimes the part we need doesn't exist in any store. In order to create custom pieces, you need to either melt the metal and cast it in a mold, or heat it until it's soft enough to shape with your hammer. Properly melting metals can be a bit dangerous in our home shop, but we can make a coffee can forge for all of our home blacksmithing needs.
In this series, I'll be exploring electromagnetic weapons, how to build them, their function and application to the future, and the amazing possibilities electromagnetism has to offer. First, the electromagnetic pulse generator, or EMP. You've probably heard of these before, and their devastating effects on electronics. A simple EMP consists of a capacitor, transformer, trigger, and coil of copper wire. This, when triggered, would produce an intense magnetic field for a brief period, similar ...
There's still about eight months before the final chapter in the Mass Effect series comes out, but some trigger happy fans are already building replica costumes and prop weapons to celebrate the upcoming release. BioWare themselves recently commissioned some of these projects, which were shown at their booth at Comic-Con 2011 a couple weeks ago in San Diego. One of these projects was the armor that turian Garrus Vakarian sports in Mass Effect 3, by Kommissar Props. But even more impressive wa...
