If you're looking to see if you're working with a live, dead, or leaking capacitor, this video is just what you need. You'll want to have a multimeter and you need to remember: capacitors can be dangerous things. They hold and release electricity very rapidly, so you can get shocked or electrocuted if you don't exercise caution.

Know how some people have a natural way of lighting up a room? Well, hacker i-am-jen has an artificial one—LED sneakers!

Daito Manabe is awesome. Last we heard of him, he was setting up Japanese school girls with glow-in-the-dark grills. Before that, he was playing himself like a human drum kit. And before that, he was just plain old electroshocking himself. In his most recent appearance, he takes his electro-pulsed facial twitches to the stage, with fellow artist Ei Wada, before an audience at Berlin's Transmediale Festival.

A perfect project for the budding roboticist in you! This video shows you how to make a small robot gripper using basic household items. Press the button and make the robot's come together! You will need: a small blow torch or butane lighter, a glue gun, a dremel or rotary tool (along with several different bits), the free cutting pattern, a permanent marker, a micro servo, some small nails or pins, a small piece of Plexiglass and a paperclip. If you don't have access to a dremel, you can fake...

Well your friend's won't stop dissing your BlackBerry Storm, and you need to show them it can actually play some games. This video shows how-to install the Gameboy emulator on your BlackBerry Storm so that you can play a whole host of cool video games. This method is pretty simple and requires your smart phone be connected to your PC, and that you go and get some software as described in the video. Give it a try and show them you ARE cool!

Make a homemade airsoft machine gun with Kipkay! You will need a basic ball point pen, a film canister or medicine bottle, and an assortment of Airsoft pellets (6 mm size pellets work the best). You'll also need access to a drill, and a hot glue gun.

Man, it's laundry day and once again you have NO quarters. Well, check out this video and you'll never need quarters again. This how-to shows how to pick the lock on a coin operated laundry machine and then rig it up so you'll never need to pay again. Sweeeet.

Do you have one of those jobs where the minutes seems to stretch by like hours? Then shaving off an extra twelve might make all the difference. All you need is cunning (to kidnap the workplace clock for the night) and hacking skills (not to worry, creator Randy Sarafan will help you with that), and you'll be the office hero. Sarafan says:

Samimy is at it again. And this time, his ingenuity has tackled a clever way to take something old and broken and restore it to something new and useful. What are we talking about? Modding a broken hard drive and some busted cell phones into a useful rechargeable USB / solar-powered light, which also acts as a portable mobile charger.

Learn about the history and technology of batteries in this informative video, and learn how to make your own voltaic cells at home, along with other scientific experiments. Jeri Ellsworth demonstrates how and provides several informative facts about the history and technology about the battery.

This is a very easy tutorial - all you need is a chosen sound effect file (like a creepy growling animal or a person screaming) and a sneaky sound system. Play it during the middle of the night and freak out your friends.

Generate electricity using only a nickel, a penny and a mild household acid like lemon juice or vinegar. Make a battery using an alternating stack of these coins and create enough electricity to power a desktop Christmas tree. Follow along in this instructional video and learn how.

If your iPad, iPhone 4 or iPod Touch is already on a tethered jailbreak, this is the tutorial on the new Redsn0w release for all you experienced users. An untethered jailbreak is a type of jailbreak where the device does not require rebooting with a connection to an external jailbreak tool to power up the iDevice. Jailbreaking allows users to get root access to the command line of the operating system, to download otherwise unaccessible extensions and themes, or install non-Apple operating...

An electrophorus is a type of capacitor that generates electrostatic energy. Most of you probably know this force as static electricity, the domain of door handles and polyester shirts. It can be used for all sorts of other fun science experiments though, and this video will show you how an old hard drive, some plastic, Styrofoam, foil, a cat, and other simple materials can be used to make a a simple functioning electrophorus.

An EMF detector lets you pick up on electromagnetic fields, a useful tool if you're into amateur ghosthunting. To make this, you will need some wire, a resistor, and an LED. You will also need an Arduino to use as a controller.

This is an easy and fun project that will add a little light to any night time celebration. Take a few LEDs in any color you want, some basic electronics gear and a hot glue gun. This will be more vibrant than any glowstick you can find in the store, and will last much longer

When you think of robots, you probably think of things that have more than three parts. Not this robot! If you want a robotics project to try that doesn't require an MIT degree, watch this video for instructions on how to build a 'Dizzy Robot' out of only some thin tin, a pager motor, a button cell battery, and this template.

If you want an electrical circuit to send power to an object, like a light, you're going to need resistors. This video, part of an excellent series on basic electronics by Scotty, will teach you how to make a circuit with resistors and an LED light, a real function piece of electronics.

Math scares a lot of would-be electronics lovers away from the field, and if you really hate math this is probably the video in this series where you stop. It will teach you how to use Ohm's Law to calculate resistance and how that applies to a basic circuit.

Japanese artist and programmer Daito Manabe uses the face as an instrument. He makes the human face involuntarily dance using electric stimulators (which, by the way, look like the same kind used for electroshock therapy). The stimulators are taped to the face, and each musical beat delivers a shock, resulting in disturbing face contortions in time to the music.
