ELECTRONICS: Electronic components distributor Digi-Key Corp. now stocks Stackpole Electronics’ RNCS series of passivated Nichrome chip resistors, a low-cost alternative for expensive and hard-to-find tantalum nitride chip resistors. Digi-Key is stocking the most commonly used values of this series in sizes 0603, 0805 and 1206 packaged on 1K reels. These products are also available in cut tape quantities. A smaller quantity can also be ordered for same-day shipment on a custom Digi-Reel®. The RNCS series employs a special manufacturing process to ensure high precision, ultra-stable performance and long life in the harshest environments. In moisture comparison testing, the lead-free and RoHS-compliant RNCS series outperformed Nichrome chip resistors and demonstrated the anti-corrosive claims characterized by tantalum nitride resistor products.
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 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.
Some humanoid walking robots are also good at running, balancing, and coordinated movements in group settings. Several of our sports robots have won regional or worldwide acclaim in the RoboCup soccer World Cup, or FIRST Robotics competitions. Others include the world's first hockey-playing robot and a trash-talking Scrabble player.
