These versatile strings or LED lights are made for signs, displays, entertainment venues, emergency exit lighting and other applications. The LEDs run off 12V dc current, and last longer, use less power, and put out less heat than standard incandescent bulbs. The modules can work alone or in groups of up to 100 units. They are impervious to shock, vibration, frequent switching and environmental conditions. They can be attached to a surface with either double-sided tape or with two screws per module (not included). Each 1.17 x 0.90 x 0.50-in (29.70 x 22.80 x 12.40mm) module has four sealed wide-angle SpiderLEDs. They come in green (525 mm, 2000mcd), white (7000K, 1300mcd), blue (470mm, 550 mcd), yellow (592mm, 800mcd) and red (636mm, 750 mcd).
Advertised as the "Most Powerful Tablet Under $100," the Kindle Fire HD 6 was too tempting for the team at iFixit to pass up. Join us to find out if inexpensive means cheap, irreparable, or just down right economical. It's teardown time!
The first photos made with a 3D-printed telescope are here and they're not as fuzzy as you might expect. A team from the University of Sheffield beat NASA to the goal. The photos of the Moon were made with a reflecting telescope that cost the research team £100 to make (about $161 US).
The increased adoption of wireless technology for mission-critical applications has revved up the global market for dynamic electronic general purpose (GP) test equipment. As the link between cloud networks and devices -- smartphones, tablets, and notebooks -- results in more complex devices under test, the demand for radio frequency test equipment is starting to intensify.
Much of the research on lithium-ion batteries is focused on how to make the batteries charge more quickly and last longer than they currently do, work that would significantly improve the experience of mobile device users, as well EV and hybrid car drivers. Researchers in Singapore have come up with what seems like the best solution so far -- a battery that can recharge itself in mere minutes and has a potential lifespan of 20 years.
