Ethernet and USB On-the-Go peripherals, coupled with compact size, are the key features of two 68K/ColdFire families from Freescale Semiconductors. Though the chips are designed for applications like industrial control, home automation and environmental monitoring that require small size and low pricing, they still have 256 Kbytes of Flash. The two, 32-bit families run at 60 and 80 MHz, delivering 2.1 MIPS. One version offers a USB 2.0 full-speed Host/Device/On-The-Go Controller, while the other provides a10/100 Fast Ethernet Controller with Ethernet PHY. In volume quantities, the 3.3V lines list for $5.49 and $7.99.
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.
