Tablets are taking over the portable-computing market, but that doesn't mean the netbooks that they've replaced are useless. It's possible to jam the processing power and battery life of most netbook models into a smaller, touchscreen-equipped package. The project is very straightforward: Remove a few parts, add a touchscreen overlay (about $80; MyDigitalDiscount), reseal the device in its new tablet form, install a driver, and calibrate the screen. And if you use an old netbook you have lying around (or buy a used one), it costs a fraction of the price of a new tablet.
Despite all the huge advances in medical technology in the past couple centuries, petri dishes, one of the most crucial pieces of equipment, haven’t changed much at all. Now a grad student at Caltech has finally brought these flat-bottomed bowls into the 21st century.

Seeing a movie outdoors used to be pretty simple. Drive a bit, pay at the entrance gate, find a parking space, and wait for the towering images to flicker into view. Some nights you'd even get a double feature. But finding a drive-in isn't easy these days. Just 370 remain in the U.S., down from a peak of nearly 5,000 in the 1950s. What to do if you yearn to experience the cinema outside? Create it yourself. For that, you need five elements: the power to drive the whole setup, a video source, a projector, a screen and a sound system.
Tinkerers have been turning flatbed scanners into cameras for a while, but this version by a Japanese modder is one of the finest I've seen--both in technical execution and the incredible quality of the massive 130-megapixel images it creates.
Using an infrared filter blocks visible light, yielding a trippy effect.
Infrared photography, which blocks visible light and captures only the IR spectrum to produce strange, beautiful images like the one above, has been around for more than a century. But it's become more popular recently, since now anyone with a point-and-shoot camera can easily take these unusual shots. Not all subjects are suitable—some objects reflect part of the infrared spectrum, making them appear white and almost ghostly, so you won't want to shoot, say, candid family shots. When done right, however, IR can work wonders. Formal portraits, for example, gain a delicate touch. Because IR softens the image, your subject's skin will be imbued with a smooth glow that effectively hides blemishes and wrinkles. Landscapes, too, take on an ethereal look.
The government is about to turn your oldest television into a useless relic. Instead of heaving the TV into a landfill, here’s how to give it a second life

By now, you've probably heard the news: Next February, television will be broadcast only in digital. If you have cable, you're already covered. If you have an old analog set—anything that pulls in signals over rabbit ears—you can buy a converter box to receive digital signals. But what about that really old TV with the fuzzy screen that takes forever to warm up? Most sets like that can't receive cable or satellite service and don't even have any A/V inputs, so a converter may not be an option.
Before you call Antiques Roadshow, however, you should know that with a transmitter kit, a cable and some solder, you can turn it into a monitor for an iPod video, a security-camera feed or an external display for a PC. Not too shabby for a piece of equipment that used to only be good for watching The Jeffersons.
