How To: Send Your Secret Spy Messages Wirelessly Through Light with This DIY Laser Audio Transmitter
Looking to transmit some super-secret audio communications to your other spy buddies? A laser is the perfect tool for getting your sounds heard from a small distance—without anyone intercepting them— even if it's just a cover of your favorite pop song. A laser audio transmitter uses light rather than radio waves to transmit sound. This is a much more secure way to send audio communications because the laser is a focused beam of light, whereas radio waves are not controlled, so they can be pic...
News: This Giant Glass Globe Turns Moon and Sunlight into Power—Possibly Even Solar Death Rays!
André Broessel of rawlemon has developed a solar energy generator that can use both sun and moonlight to create usable power. Oh... and it's gorgeous.

A New Breed of Invertebrate: Half-Rat, Half-Silicone Cyborg Jellyfish
A team of scientists might have just put Jellyfish Art out of business with their new cyborg jellyfish. By arranging the heart cells of a normal rat on a piece of silicone, they've successfully created their own Franken-jellies. When in salt water with a fluctuating electrical field, the rat's heart muscles on the rubbery silicone contract the lobes downward and back up, which mimics the pulsing movement of a young moon jellyfish swimming.

How To: Make Surface-Mount Electronics at Home for Smaller, Cheaper DIY Gadgets
Whenever we make a homemade circuit, we use what are called through-hole components. Any components with long metal leads is a through-hole component. They are great for soldering to, but it's tough to fit enough through-hole resistors and capacitors into a smartphone. To get those last microns, we have surface-mount components for SMDs (surface-mount devices). These are all of those teeny, tiny things you see when you crack open your digital camera or laptop case.

How To: Prank an Entire Dorm with a Perfume-Spraying Swiffer WetJet Booby Trap
Pranks are fun, but finding a way to maximize the affect of a prank can be tricky. Toilet papering the whole campus or repainting all of the parking spaces slightly smaller can take a long time and a lot of resources. A better plan of attack is to booby trap the choke points where your victims are forced to pass through. Think like a guerrilla. A dorm doorway is a good idea.

Post-Modern Vandalism: How to Hack Together These Everlasting Light Graffiti Throwies
Graffiti is a great way of getting your message out to the masses. The earliest known graffiti dates back to 30,000 years ago and used the traditional apply-paint-to-wall technique. Though our paint now comes in cans and not from scavenged berries, the actual graffiti process hasn't really evolved from those first cave paintings.
How To: Design Your Own Custom Arduino Board Microcontroller
Microcontrollers are great. You can do anything from water your garden to catch wildlife trash diggers in the act—and on the cheap. I prefer to use the Arduino microcontroller because of the large and helpful community built around the website. Though it is my favorite, there are some drawbacks to using an Arduino board in every project. It gets expensive, the board can take up too much space, and the rat's nest of breadboard wires are a pain to repair.
