How To: Create a PCB Etchant That Automatically Improves After Each Use

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 etchant at home with everyday chemicals! Better yet, our new etchant will turn an eerie green color rather than the dull brown of ferric chloride.

How To: How Red-light Cameras Work

As you may have seen in your city or town, red light cameras are on the rise in the United States. In many instances in my area, these cameras have sprung up seemingly out of no-where, and mostly without any reason. Over use of these systems can make privacy (even on the road) a fleeting possibility.

Glass Cutters Are for Tools: How to Dissolve Glass Using Sodium Hydroxide

Glass is one of the least reactive substances known to chemistry. It is the standard container material for almost all lab chemicals because it's so inert. But there are a couple of substances that have strong reactions with glass. Sodium hydroxide, aka solid drain cleaner or lye, can easily be stored in glass as a solid, but when molten, it reacts violently with glass and can actually dissolve it away! So, the next time you clog up your drains with broken glass beakers and flasks, rest assur...

Know Your Rights: How to Escape Unlawful Stops and Police Searches with Social Engineering

Law enforcement can make a lot of folks cringe. Too often do we hear on the news, and even experience in our own lives, the unjust way that an unacceptable portion of law enforcement treat the very citizens they are supposed to protect. People's rights are violate each and every day by law enforcement, simply because they are timid and uneducated with the laws of society. This dirty trickery shouldn't be played on harmless citizens under any circumstances.

News: New Biometric Device Steals Fingerprints from 6 Feet Away

Dactyloscopy isn’t going anywhere. Forensic science has much relied on fingerprinting as a means of identification, largely because of the massive amount of fingerprints stored in the FBI’s biometric database (IAFIS), which houses over 150,000 million prints. And thanks to the departure of messy ink-stained fingertips, biometric analysis isn’t just for solving crimes anymore.

But there's one more thing, and it's something we usually only see one other time each year— fireworks.

How to Be Your Own SpaceX: Design, Build & Test Liquid-Fueled Rocket Engines

Move over NASA— SpaceX is taking over. Well, not really. But today, the privately funded spacecraft company broke all expectations when their Dragon capsule fell to a soft landing in the Pacific Ocean, completing an undoubtedly successful demo flight of nearly two full trips around Earth. It was the first re-entry of a commercial spacecraft ever, bringing commercial space transportation closer to reality.

How To: Build a Wireless Energy Transfer Array to Power Light Bulbs Without Plugging Them In

In this article, I'll show you how to built a Wireless Transfer of Energy Transmitter. Simply put, this device will send electricity to a florescent light bulb and light it up, from up to three feet.

However, the circuit described in this article consists of a flyback transformer, n...

How To: Be a Navy SEAL

There's no doubt about it—the most elite military force in the United States is hands down, the Navy SEALs. They can operate at sea, in the air and on land, and their ability to conduct missions underwater separates them from most other military units in the world. They've fought in World War II, Vietnam, Granada, Afghanistan and Iraq, but have gained some serious hype in recent years thanks to SEAL Team Six, aka DEVGRU, aka NSWDG, who saved Captain Richard Phillips from Somali Pirates in 200...

Minecraft: Her Crushed Dreams
