Over the next few months, I'll be focusing on building a fully functional, long range UAV. This series will consist of several in-depth articles on my progress and the steps involved, so you can follow along and build your own unmanned aerial vehicle! The budget is $800 and w ...more

The new iPhone 5 was just revealed yesterday, and it's 18 percent thinner and just 1/5 the weight of its 4S predecessor. It's also taller with a larger screen, which gives you a fifth row for apps now. As far as speed is concerned, it has a speedy A6 chip and can tap into wire ...more

Making your own circuit boards can be a daunting challenge. You have to design a schematic, test it on a breadboard, design the board layout, and then after all of that, you still have to print and etch a board! Luckily, we have Fritzing. Fritzing is a free open-source PCB d ...more

Smartphones are crazy awesome. You can do your banking, track your children, find directions, and even pretend to have a mustache. The only thing that these personal supercomputers are missing is physical interaction with the environment. I wanted to be able to call my house ...more

Etching your own circuit boards is tons of fun, but etching requires strong chemicals to dissolve the copper plating on blank circuit boards. The normal ferric chloride solution works well, but can be expensive and leaves permanent stains. Luckily, we can whip up our own etcha ...more

In my last guide, I showed how you could crack the combination of any Master Lock combination padlock in 8 tries or less using my online calculator. Now, as promised, I'll be showing you how I devised the attack, which is based off the well-known technique that reduces the 64, ...more

A couple of months ago at the Black Hat security conference, hacker Cody Brocious gave the hotel industry a nasty surprise when he figured out how to hack the locks made by Onity that are used in millions of hotels worldwide. The reason his hack is so impressive is because it ...more

There are hidden Wi-Fi networks all around you — networks that will never show up in the list of available unlocked and password-protected hotspots that your phone or computer can see — but are they more secure than regular networks that broadcast their name to any nearby devi ...more

The USB Rubber Ducky is a famous attack tool that looks like a USB flash drive but acts like a keyboard when plugged into any unlocked device. The Ducky Script language used to control it is simple and powerful, and it works with Arduino and can run on boards like the ultra-ch ...more

Smartphones and other Wi-Fi enabled devices send radio signals called probe frames to locate nearby wireless networks, which makes them easy to track by listening for their unique MAC address. To show how this kind of tracking works, we can program a NodeMCU in Arduino to snif ...more

If you want to get started sniffing Wi-Fi networks, you usually need to start with a wireless network adapter. But thanks to a Wi-Fi sniffing library written in Arduino and the ultra-cheap ESP8266 chip, you might not need one. For less than $10 in electronics, you can build a ...more

Keys are on the way out. They're clunky, take up precious space, and slow you down when you have tons of identical-looking gold ones on your keyring. Everything we can open with keys can now also be opened with wireless technology in just a click—so why use keys anymore? Sure, ...more

Homemade circuits are amazing. You can build any kind of circuit on a simple perfboard, as we have seen in previous projects. However, some projects require very tiny circuit boards. We could special order some boards from a printed circuit board (PCB) factory, but that will m ...more

In this article, I'll show you how to send SMS messages with Python. You'll need Python 2.7 or later, urllib and urllib2. The code basically uses an online text messaging service to "POST" html data, as if a person was entering the data themselves. The uses for something like ...more

General Electric isn't known for their Christmas lights, but maybe they should be, because their GE Color Effects are pretty awesome. Especially the LED Color Effects G-35 String sets. And especially when someone named Darco hacks them. Darco, whose real name is Robert Sun Qu ...more

The USB Rubber Ducky is a well-known hacking device in the cybersecurity industry, but it needs to be preprogrammed before it can be used. That means it's not easy to issue commands to a target computer since you can't interact with it from afar after plugging it in. And if yo ...more

The ESP32-CAM is a convenient little camera module with a lot of built-in power, and you can turn one into an inconspicuous spy camera to hide in any room. There's only one issue: it does omit a USB port. That makes it a little harder to program, but with an ESP32-based board, ...more

Ever wonder how all of those tiny chips and components can fit inside your laptop or smartphone? If you tried to squeeze them in there yourself, your laptop would quickly become too heavy for your lap, and your mobile phone would need wheels to stay mobile. The secret to mini ...more

Whether you're in an airport, restaurant or waiting room, the insidious grip of televisions on human life is omnipresent. Sometimes it's nice to talk to other human beings while looking at them directly—actually hearing what they have to say. Thankfully, there's a DIY device ...more

The cell phone has come a long way. The very first "mobile devices" were made and used by the military in the late 1930s, with the first commercial mobile telephone service introduced by Bell in 1946. These devices were hardly what we'd call mobile today—some took up the whole ...more

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 in ...more

April Fools may be over, but any day is a good day to prank someone, and the best time to do it is when everyone's eyes are glued to the television. Turning off a TV during a climatic moment is the best way to prank a TV-obsessed sibling or friend, but it's even more hilariou ...more

Bash scripting is a convenient way to automate things on any Linux system, and we're going to use it here to automate certain tasks we use all the time. Bash is a simple language for stringing together several different Linux utilities. Its simplicity makes it easy for beginn ...more
