The company's newest single-axis controller/driver, designed for lower-cost network support, has communications options such as RS232, RS465, CAN and Ethernet. It allows CAN-using devices to work at the same time with a supervisory network that uses RS232, RS485 or Ethernet. It works well with the company's NEMA 17 and NEMA 23 frame I-Grade step motor/encoders. It comes with breakouts for power, communications and I/O. Its closed loop control (servo) of a stepmotor offers all the accuracy of a traditional servomotor, with better torque for applications up to 2,000 rpm. It works with only one cable for motor and encoder signals, and functions well on lines up to 50 ft. It comes with 12-48V dc input power, built-in voltage clamp and power resistor, four analog inputs, electronic gearing and camming, SSI encoder interface and many other features.
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.
