Looking to be the world's best violinist or fastest banjo player? If you didn't start practicing when you were a kid, learning a new stringed instrument is extremely challenging. But an upcoming device may change all of that, if you don't mind being shocked by 28 different electrodes.

The idea that you could buy a cellphone sized video camera that shoots 720p for a hundred bucks would literally seem like nonsense to me five or six years ago, as I sat trying to get a shot worth looking at out of my old Sony pd150. They're here, though, the Flips and iPhones and Kodaks and whatever else and while most of their impact can be measured in the increased frequency of Bieber-tribute videos hitting youtube, having a $100 hd camera also puts me in a mind to go - me a regular old idi...
Andrew Odewahn of O'Reilly Answers posts a HowTo on creating 3D(ish) images through simple processing. Odewahn employs the practice of stereoscopy (a technique for creating the illusion of depth in a 2D image):
How do you clean the blades of a ceiling fan without potentially hurting yourself? For an easy solution, simply use a stepladder and a pillowcase. Encase one blade of a ceiling fan with a clean pillowcase, and then pull the pillowcase towards you, which removes dust from the top of the blade and brings dust down into the pillowcase. Turn fan and repeat for every blade until the entire ceiling fan is clean.
In an attempt to get parents to pick up their kids on time, a number of Israeli day-care centers decided to impose fines on parents who show up late.
NK5 is a genuine wizard with an old monitor. He's hacked together everything from an electric kitty fence to a Halloween hologram using the guts of an old CRT.
The recent report of the ubiquity of extrasolar planets coupled with the fact that it bodes well for searches for life friendly Earth twins, brought me back to my reading of Carl Sagan's 1966 Intelligent Life In The Universe and later article in Sky & Telescope where he came up with a remarkable number in favor of such.
Hardware hacks are something I feel we don't get enough of at Null Byte, so today I figured I would introduce a fun one. I've always been a curious hardware hacker. Taking things apart and learning how their internals work has always been a part of my nature. Quite some years ago, my father showed me a really cool trick on how to hack normal radios to scan frequencies that are normally non-listenable. This little hack allowed us to scan frequencies belonging to law enforcement, and even frequ...
Remember the good ol' days when you actually had to swipe your credit or debit card to make a payment at the store? Now all it takes is a flick of the wrist to purchase goods with your card, thanks to RFID (radio-frequency identification) technology from Chase (blink), Visa (payWave) and MasterCard (PayPass). But soon "contactless" payments will be made by an entirely different beast—NFC, which stands for near field communication.
Laser gun + killing mosquitoes = lots of little boy fun, but what's it all about? Quite possibly the most entertaining, thrilling, and well, downright life-saving presentation at this year's TED conference was Intellectual Ventures' mosquito death ray.
Today's fancy cars come with all sorts of options, from power mirrors to working seat belts. Some of us condemned to live in the reality of capitalist recession have no car, or perhaps a very modest one. But your modest car can still have some cutting edge technology wedged into the trunk and dashboard if you know what you want and where to look for parts. Today, we make a parking sensor using a sonic range finder, just like in the vehicles our owners drive!
What if your fridge knew your food and expiration dates? What if your fridge could tell you which ingredients are missing and where you can get them the cheapest?
There are several ways you can go about creating your NURBS helix curve in Maya; I will demonstrate the two easiest ones.
As much as streaming services like Apple Music and Spotify have dominated the music industry, radio is still alive and well. And why wouldn't it be? Free music, 24/7? It's a great deal. That's why it's so cool that your iPhone can instantly tune in to your favorite radio station, even one across the country.
Welcome to Microwave Energy—the next part of my Making Electromagnetic Weapons series. For the Electromagnetic Pulse Generator, check out the last three articles (One, Two and Three).
Austrian composer Peter Ablinger has created a "speaking" piano. Ablinger digitized a child's voice reciting the Proclamation of the European Environmental Criminal Court to "play" on the piano via MIDI sequencer. Apparently, the computer is connected to the piano, which analyzes the human speech, and then converts it to key-tapping.
The Stun-Gun In this article, I'll show you how to make a small, weaponized highlighter. Before I get into how to built this device, let me warn you. This device is harmful! When used, it can cause burns and/or serious muscle spasms. The voltage is potentially deadly! DO NOT attempt to build this device unless you are experienced with safety, electronics, soldering, and understand circuit schematics.
Social network fatigue sets in when it starts to feel impossible to keep up with all that new content from your friends, followers, and acquaintances on a daily basis. You lose track of stuff you wanted to read more about, and you miss important news from your friends, but are bombarded with inconsequential details from people you don't actually care about. What's the solution? Filter your streams so that you only see the content you do care about, and get rid of the rest.
