All you've got to do is a some simple wiring and a little digging in the garden.
Looking for a front-yard upgrade that'll have visitors beating a well-lit path to your door? The answer is an easy to install pathway lighting set. Too often, we're forced to choose between form and function. But when it comes to the route that leads to your front door, you can have it both ways: a pathway lighting system that combines the safety and security of good exterior illumination along with decorative elements that enhance your landscaping. Even though you might not have any experien...
Here is the movie trailer for "Crank 2 : High Voltage"
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 ...
Solar panels are an amazing invention. Catching energy from the Sun before it even enters Earth's food chain, photovoltaics are like an all-natural nuclear power plant. Unfortunately, the constituted parts of a solar panel are rare, valuable, and subject to the coercive forces of market competition.
Tesla coils are totally insane, yet undeniably captivating. And they can be used for many things, from electric painting to dueling musical battles. But one trigger happy fellow has a different use for Tesla's lightning shooting coil. A weapon.

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.
Here's a little gadget I made based on the concept of a potato launcher, a stungun, and a dart gun. The gun uses an explosive gas (butane) to launch a charged high voltage capacitor at a target. The gas is ignited by a small spark, created by a pulse transformer. The trigger automatically fills the combustion chamber with the correct amount of gas, then ignites it with the pulse transformer. The result: a long range stun dart gun.
In this article, I'll show you how to create a simple yet effective way of scaring off intruders. Of course, there are methods around this approach, but it's great for office pranks and general fun. The project requires a little background knowledge in electronics and circuitry, like reading schematics and using a soldering iron.
In this article, I'll show you how to make a simple touch-triggered switch. This is very useful for various electronic projects, from a simple bedside light to a flat panel touch keyboard. The circuit can vary in switching power depending on the transistors you use. For example, if you're looking into creating a 120V light that turns on when touched, you'd need two powerful transistors and an isolation relay. However, a simple flashlight that turns on when touched would only take a couple of ...
Michael Faraday was an English chemist and physicist - a bona fide electromagnetism and electrochemistry genius. Without him, men couldn't walk on live electrical wires. Wait, what?

This is the third part of my electromagnetic pulse series (see Part One and Part Two). By now, I've covered the hardware and general concept of electromagnetic pulse generators, but how exactly do they disable electronics? How can an invisible field of energy have such a catastrophic effect on computers, cell phones, and most any other electronics? I'll be answering all these questions in part three of Making Electromagnetic Weapons.
In this series, I'll be exploring electromagnetic weapons, how to build them, their function and application to the future, and the amazing possibilities electromagnetism has to offer. First, the electromagnetic pulse generator, or EMP. You've probably heard of these before, and their devastating effects on electronics. A simple EMP consists of a capacitor, transformer, trigger, and coil of copper wire. This, when triggered, would produce an intense magnetic field for a brief period, similar ...
Low vision therapist Diane Michels share tips on how to improve what you can see for people with low vision challenges. Ideas like improving lighting by using lighter lampshades or dusting light bulbs, shields for your computer monitor to reduce glare, and contrasting colors for up close work are among the ideas shared. Improve reading for people with low vision issues.
The low golf shot is particularly useful when you are playing a links course and the wind is blowing, as it stops the ball ballooning and losing distance in its flight. It's also the best way to punch the golf ball out from beneath the branches of a low, overhanging tree. A lot of golfers play this shot the wrong way . Keep the golf ball low.
It's what every astronomy-loving geek has always wanted... a beautiful, twinkling home galaxy. As Instructables user MrTrick rightly warns, this project is no small feat. Be prepared to get schooled in:

Your favorite device is running low on juice and needs a couple new AA batteries—and with a quickness. You run to the store and grab the first pack of AAs you see. But should you? There's tons of options available, so which make and model gives you the most power per dollar?
Nikola Tesla. He was the man behind some of the greatest inventions of all time, including radio and alternating current. But perhaps his most visually fascinating invention is the Tesla coil. While maintaining a low current, it can produce dangerous high frequencies and voltages that can well exceed 1,000,000 volts, discharging it in the form of electrical arcs very similar to lightning.

As sheltering at home orders ease up, we still have to remain respectful of social distancing. Camping is one of your best options. You'll avoid the crowded beaches and trails while still soaking up nature. Right now we can all use some fresh air and sunshine.
In this article, I'll show you how to build a simplistic circuit to generate negative ions. Negative ions have been known to contribute to fresher air, happier mood, and general health benefits. However, they also look amazing in the dark (check out the photos below, purple plasma is amazing!). And if all else fails, they make a cool nightlight. If you've ever been around a Tesla coil, cathode ray tube TV or sometimes even on a trampoline, you've probably noticed that smell; the smell of "sta...
Instructable user samsmith17's solution for riding in the dark is a lot snazzier than your typical bicycle light:
Who says nothing productive ever came out of doodling? Certainly not the hacker responsible for this fun (and at least somewhat functional) paper-and-pencil touchpad, which takes advantage of the natural conductivity of graphite: There isn’t much to explain here. It just uses pencil graphite on paper as a kind of two dimensional potentiometer. Four voltage dividers between 5v, 2M ohm resistors, the paper, and my grounded finger feeds signals from each corner into an Arduino. The Arduino does ...
