I love making beeps and bloops with the Arduino pitches library, but sometimes archaic 8-bit tunes just don't cut it. Whether you want your robot to terrify your enemies with a demonic synthetic voice, you just need a pocket boom box on the go, or you want to a miniature guitar amp, a simple LM386 amplifier can crank up those signals loud enough to play through any speaker.
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.
Valentine's Day is almost here, and if you're like me, you're scurrying to do something special for your mate. The standard chocolates and flowers just isn't cutting it anymore, and you can only make so many homemade cards before it becomes banal and meaningless. So, what can you do that shows you put some work into it, while not breaking the bank?
This weekend, hackers broke into the servers of the popular shoe shopping site Zappos, giving them access to the personal information of 24 million Zappos customers. The user data taken included names, email addresses, billing and shipping addresses, phone numbers, the last four digits of credit card numbers, and encrypted passwords. However, full credit card data was not lifted, and passwords were cryptographically scrambled.
Building a DIY Alarm System: The Concept So, you want to protect your property, or maybe a room, car, or even your backyard. The concept of an alarm system is to notify the "alarm administrator" that there is an intruder entering the previously designated boundaries. The triggers for this boundary could be as simple as a pressure sensor, or as complicated as a laser network. They all do the same thing, but some work better than others.

A modern iPhone is capable of running sophisticated, exquisitely-rendered games that rival titles on current-generation consoles. However, there is some value in classic video game titles, whether you grew up playing games on the Atari 2600, Nintendo Entertainment System, and Sega Genesis or not.
People fundamentally distrust magicians. And they should. The illusions they proffer are just that, illusions meant to astound rather than tangible interactions and results that have weight and meaning in our real world. Our lizard brains know this, and, no matter what the outstanding feat of "magic" presented, we nevertheless hold fast to our survival-based grip on the truth: we just saw simply "can't be real."
Router gateways are responsible for protecting every aspect of a network's configuration. With unfettered access to these privileged configurations, an attacker on a compromised Wi-Fi network can perform a wide variety of advanced attacks.
Your phone's keyboard is one of the most commonly used apps. Whether you're typing out status updates, sending private messages, or just bombarding everyone in sight with as many emoji as you possibly can, you probably couldn't get by without a good keyboard app.
Typography is an important aspect of the video editing process.

Enlight Videoleap for iOS makes this all easy.
I noticed the neon yellow sign at the new location of Pho Bar in Chinatown right away. The sweeping cursive yellow letters spell out "Crazy Rich Broth"; the same phrase printed on the back of servers' shirts. It's the kind of minimalist but colorful design feature that is especially popular on Instagram at the moment — shots of patrons in front of a glowing sign.
Android's settings menu is actually pretty daunting. There are options for nearly everything, so in the sea of various menus and submenus, it's easy to overlook important privacy and security settings. On Google's Pixel phones in particular, there are 20 such settings that you should double check.
The tactic of brute-forcing a login, i.e., trying many passwords very quickly until the correct one is discovered, can be easy for services like SSH or Telnet. For something like a website login page, we must identify different elements of the page first. Thanks to a Python tool for brute-forcing websites called Hatch, this process has been simplified to the point that even a beginner can try it.
It's common for IoT devices like Wi-Fi security cameras to host a website for controlling or configuring the camera that uses HTTP instead of the more secure HTTPS. This means anyone with the network password can see traffic to and from the camera, allowing a hacker to intercept security camera footage if anyone is watching the camera's HTTP viewing page.
Apple Watch owners know the struggle — it's the end of the day, and those rings aren't met. Whether you forgot your watch before hitting the gym, let the battery run out, or just didn't move enough, you could feel the sting of fitness failure. But it doesn't have to be this way. You can actually close your Activity rings yourself; it just takes a little know-how.
MoviePass was once the best subscription service on the market for getting cheap movie tickets. For the price and the number of films you could see and save money on, it was unbeatable, but recent changes to the service have made it less enticing. While it still works well for some users, others may have to rely on other options. Personally, I'm leaning toward the latter.
The macOS 10.14 security update tried to make parts of the operating system difficult for hackers to access. Let's take a closer look at how its new feature works and what we can do to spoof the origin of an application attempting to access protected data.
Hackers often rely on lazy system admins and unpatched vulnerabilities to get access to a host. Keeping intruders off of our machines requires us to update daily, only run the services we need, and read the code, among other things, but we can still make mistakes. Luckily for us, we can limit the damage caused by those mistakes by running SELinux.
It's easy to have your password stolen. Important people like executives, government workers, journalists, and activists face sophisticated phishing attacks to compromise their online accounts, often targeting Google account credentials. To reduce this risk, Google created the Advanced Protection Program, which uses U2F security keys to control account access and make stolen passwords worthless.
Format strings are a handy way for programmers to whip up a string from several variables. They are designed to save the programmer time and allow their code to look much cleaner. Unbeknownst to some programmers, format strings can also be used by an attacker to compromise their entire program. In this guide, we are going to look at just how we can use a format string to exploit a running program.
The one thing that separates a script kiddy from a legitimate hacker or security professional is the ability to program. Script kiddies use other people's tools, while hackers and security pros write their own tools. To that end, we're going to see how a stack overflow vulnerability allows us to flood a variable with enough input to overwrite the instruction pointer with our own commands.
Surveillance is always a useful tool in a hacker's arsenal, whether deployed offensively or defensively. Watching targets yourself isn't always practical, and traditional surveillance camera systems can be costly, lacking in capabilities, or both. Today, we will use motionEyeOS running on a Raspberry Pi Zero to create a small, concealable Wi-Fi connected spy camera that is both affordable and easily concealed.
Every time you make a call or send a text, you're giving the recipient your phone number. This can be quite the security vulnerability, opening yourself up to scammers, spammers, and the feds.

(Hint: Using Tor is not enough.)
