New gearbox runs smooth, quiet and with more torque
The new AE series uses a patented one-piece shaft carrier design, and is supported with an oversized ball bearing straddle mount to provide more radial and axial loading capacity. Its stainless-steel output housing and patented sealing technology makes it a versatile, low-cost servo grade gearbox. Its new AE planet gears and greater tooth-to-tooth contact ratio make for more than 100 percent torque capacities versus other spur-gearing geometry. It has an optimized Helix angle that makes it run smooth and quiet, even at extreme speeds. It can go up to 10,000 rpms input with less than 8 arc-min and less than 56 dB. It is available in seven sizes (AE 050, 070, 090, 120, 155, 205 and 235), and is equipped with every single stage ratio (3, 4, 5, 6, 7, 8, 9 and 10:1). It has more binary (double stage) ratios than others of its type. It's covered by a two-year, tip-to-toe warranty and delivery is guaranteed within two weeks or it's free.
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.
