As Amazon gets set to ship out the Kindle Paperwhite, its new e-ink e-reader that features an integrated light, its chief rival appears to be getting a price cut. At least two major retailers -- Target (shown above) and Wal-Mart -- are now advertising the Nook Simple Touch With GlowLight for $119. That's $20 less than the original $139 price, and the exact cost of the entry-level Paperwhite (which, unlike the Nook, includes "Special Offers" ads).

When Barnes & Noble introduced the Nook GlowLight earlier this year, it had problems keeping up with demand (it later admitted … Read more

Here in Albuquerque, we have a 5-feet-to-pass law. You need to give cyclists that much room when you go around them in a car. It's easy to visualize when you have marked bike lanes, but some drivers push the limits on unmarked streets, especially at night.

If bicyclists carried their own bike lanes with them, it might help alert motorists to give them proper room. That's where Xfire's clever Bike Lane Safety Light comes in. The light uses two 5mW red lasers to create bike lane markings and five red LEDs for increased visibility overall. … Read more

The iPhone 5 may have the same light leak problem that initially plagued other Apple devices.

Chiming in on the MacRumors forum, one user posted a photo of the new iPhone in relative darkness, showing a small flash of light coming from the top of the device behind the glass panel. Another posted a similar picture displaying the same light leak. Other users have since added to both discussions, reporting the same issue on their new iPhones.

Apple's Discussion Forums have also picked up a few complaints about the light leakage.

Some users say they received a replacement unit … Read more

The mundane task of turning on the lights generally involves a simple flick of the switch, but Norwegian designer Stian Korntved Ruud thinks it could get a lot more interesting.

Korntved Ruud, who graduated last year with a master's in industrial design from the Oslo School of Architecture and Design, created "Circuit breaker," a series of five switches that force users to interact with the panel and thus present new ways of turning the lights on.… Read more

Adding blinking lights to anything is a surefire way to make it totally obnoxious. For some of you, that's a good thing.

Here are two techniques you can use to add sound-reactive lights to your stereo, boom box, computer, or pretty much anything that makes music.

The first option is to use something like an EL Wire Sound Kit. These are sold online from various places and include some combination of electroluminescent wire, a power adapter, and a special power inverter that drives the wire's power in response to sound picked up by an integrated microphone.
