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!
Christian Cantrell, Adobe's Air Product Manager and Evangelist, has released a video to demo websites that take advantage of the motion sensors in a mobile phone, tablet, or laptop via JavaScript. Now, let's take a look through the code and break down the core pieces that you'll need in order to build your own sites that can determine the 2-axis tilt, 3-axis gyroscope, and compass direction of the mobile device it's being displayed on.
I'm back with the third part to my laser weapon series (see part one and two), and I'll be explaining the function, application, and potential of semiconductor lasers, aka laser diodes.
Did you know there is hidden data in your digital pictures? Well, there is, and that data might be a security risk to you. Think back at all of those pictures you're in and are connected with. I'm sure some of those you'd like to distance yourself from. And surely you wouldn't mind checking out the metadata in a few of those images. In this article, we'll be going over how to do just that.
A practice amplifier can be just about anything, but by definition it’s probably not something you are going to gig with.
This Revit Architecture 2009 video tutorial covers how to import geometry from Rhino via Autocad. Really this technique will work for any program that can output a .sat. Even if the program cannot, Rhino imports many formats (such as .step or .iges) which you can then export as a .sat for Autocad. The basic logic in this tutorial is to create a tower which has geometry too complex to build in Revit. We then pass it through Autocad to export a closed solid .dwg. As of now Rhino only exports .d...

Welcome to Compute & Conquer! This article may seem a little basic. We all have an idea of what a computer is but the fundamentals are necessary. Without knowing how something works, how can we determine a problem and find a solution when something goes awry? Way too often, I find myself helping someone with a very "easy to fix" problem on their computer. A problem which could have either been avoided or fixed had they had the basic knowledge of how to use a computer. Even worse, I've seen to...
In this article, I'll show you how to prank your friends on April Fool's Day with the very popular Google Voice, a computer to land/mobile calling feature. Basically, Google allows you to play whatever you like through the microphone port on your computer, and play it right through to your victim's phone. Whether it's Rick Astley ("Never Gonna Give You Up") or a text-to-speech application, general hilarity always follows.
Here's a simple and easy addition to your own Jacob's Ladder. If you don't have one, here's how to make a Jacob's ladder.
In this article, I'll be showing you how to make a cool visual representation of sound using an old cathode ray tube (CRT) television, a stereo, and a sound source. You'll also need a pair of wire cutters, and a few screwdrivers. To properly understand this project, it's a good idea to learn a little bit about how CRT TVs work. Check out this article on how they work.
When it comes to coffee, some people just like perfection. Most would agree that the best cup of coffee comes from home, after roasting your own green coffee beans. But not everybody has the time or money to have complete control over their coffee's flavor. Roasting via stovetop or oven produces mélange (not quite perfection), and home roasters can be pricey.

As advanced gaming systems continue to evolve, older classics like the Nintendo Entertainment System (NES) are one step closer to extinction. They're rotting in the basements of gamers. They're gathering dust at the local pawn shop. Or worse... being thrown out in the trash like a used up condom. But not everybody is getting rid of their NES—or more specifically, their NES controllers.
Age doesn't matter in the world of programming, only skills, and recent high school grad Jack Eisenmann definitely has them. He recently built a homebrew 8-bit computer from scratch, calling it the DUO Adept. A worn television makes up the monitor and speaker system, an old keyboard acts as the input controller and the actual computer itself is housed inside a clear Rubbermaid container, consisting of 100 TTL chips and a ton of wire.
It's been about five months since Google first unveiled their prototype future computers running Chrome OS, and the time is nearly here for the Chromebooks to be unleashed on the public. But there are a lot of qualms over the release of Chromebooks, with most criticism coming from their lack of traditional laptop-based features such as an optical drive, storage space and the ability to run comprehensive software programs like Adobe Photoshop.
As a kid, my favorite thing to do at the Natural History museum was a midday stop, when my family strolled past an antiquated looking vending machine in the museum's musty basement. The Mold-A-Rama machine was oddly shaped, George Jetson-esque, and spewed out made-to-order, brightly colored plastic dinosaurs. There was such joy in watching the liquid wax pour into the mold, and then eject a warm, custom toy—well worth the dollar or two demanded. A version of this tradition was recently elevat...
Every key on a telephone keypad has its own sonic signature, a sort of calling card composed of two distinct tones: one high, one low. While it's easy to tell the difference between the individual pitches in a single row—see, for example, this article on using your cell phone as a musical instrument—, it's often difficult to differentiate between notes within the same column. Unless, of course, you outsource the work to a computer! Which is what Uruguayan hacker [Charlie X-Ray] recently set o...
CNA skills may vary from state to state. Depending on your state of residence, the skills section of the CNA certification exam will consist of three to five randomly chosen skills.
Let’s say you have a MOOG keyboard you want to send into Logic. To set this up, there’s a few things to do in Logic.
Burger Records, a vinyl/cassette label based in Fullerton, Ca. and run by members of Audacity and Thee Makeout Party, have reissued 3 cassette tapes from Cleaners From Venus. "Midnight Cleaners" (1982), "In The Golden Autumn" (1983), and "Under Wartime Conditions" (1984). These cassettes have been loooong out of print and nearly impossible to find. If not for blogspots, some of these tracks would never be heard again. Martin Newell (Mr. Cleaners or Mr. Venus???) started recording and releasin...
Hello null byte!! I found a local local privilege escalation exploit on Exploit-db known as CVE-2015-5889: issetugid() + rsh + libmalloc osx local root by rebel. You can visit the link here or find the code on pastebin here.
I can't begin to tell you of the many times my friends and I get into arguments that eventually lose any semblance of structure, becoming shouting matches where we just lob the stupidest, meanest insults we can fathom.
In this how to, I'm going to explain how to install a new TV socket. Parts
+Tom Anderson of MySpace has been very active on Google+ over the first week, and he's not shy with his thoughts on the evolution of the industry he once owned. Here's his take on this morning's Facebook announcement and Mark Zuckerberg's response when asked about Google+.
Steam has been a game-changer in the PC indie game market over the last eight years, making smaller games available to millions of users at lower prices than ever before. And few times in those eight years have there been as much indie awesomeness on sale for as little money as this weekend.

In my last article, I discussed how you could download almost any video from almost any video sharing site using the free NetVideoHunter add-on in Mozilla Firefox. Now in this article, I will discuss how to convert those videos you’ve downloaded to any format—also for free. Most of the time, the videos you download with NetVideoHunter are in FLV (Flash video) format, which is something that not all video players can play. That’s why I made this article.
Bash (Shell) Scripting for Beginners Intro
There are many impressive accomplishments in Minecraft, too many to name in fact. Sprawling builds, complex machines, and massive servers are the hallmark of Minecraft and things keep getting bigger and better. No one doubts the epic scale Minecraft has reached, but every once in a while something grand comes along that sets a new benchmark in awesomeness. By far the most recent step in this long line of big ideas was an innovation pushed forward by YouTube user Kimundi2. The premise of this ...
I like to grow vegetables all year round, and I couldn't afford the big gas bulbs, or the power to run them. The big gas bulbs:
I'm sure most everyone has some kind of fluorescent light source in their home; those long white tubes that emit a bright white light when turned on, or maybe a few of the CFL power-saver bulbs. These bulbs actually require very little "power" (i.e. a high voltage:almost no current ratio) to emit light. In fact, static electricity is enough to make them flicker. Inside these tubes is a gas, and when electricity flows through that gas, it gets "excited" and produces light.
In this article, I'll be showing you how to make a simple yet effective static electricity generator. Basically, this device allows you to carry a constant static charge on your body and discharge it on anything grounded or of opposite polarity. The electricity generated is around 8-10 kV, at a very low current. The shock is enough to startle your friends, just like a static shock from a trampoline or carpeted room. You'll need a little experience in soldering and circuit design to build the ...
In this article, I'll show you how to create a simple yet accurate demonstration of the "rising ionized gas" principle. In other words, a transformer, two metal prongs and lots of evil laughter. Remember those large "towers" in the background of Frankenstein movies with a "lightning bolt" rising upwards every few seconds? That's called a Jacob's Ladder; one of the coolest awe-inspiring demonstrations of high voltage. Here's a video of the final product: Materials and Tools
Here's another delicious Byte. Ucha Gobejishvili, a Georgian Security Researcher under the handle of longrifle0x, discovered two cross site scripting (XSS) vulnerabilities on the official website of Forbes. He discovered the hole in two different locations on the site, and has already informed the website of the vulnerability.
