The Too Big, Too Light & Too Strong MDR-EX1000 Gentle & Sweet to Ears

Sony has come out with a very large 16 mm dynamic driver. It is almost as big as one can get on any of the IEM. The uniqueness being that its 16 mm driver is using a variety of modified Liquid Crystal Polymer compound, and is the excellent material available for developing the formation of diaphragm out of it, having higher rigidness properties associated with high degree of internal loss as a result of deploying modified liquid crystal polymer, this all are responsible for high accuracy in conversion of signals to the sound waves.

In addition there is “transverse field pressing” technology adopted in the manufacturing process resulting boosting of the magnetic force of 440KJ/m3 yielding very powerful neodymium magnets put to use in the drivers, achieving superior sensitivity to the minutest alteration of signal.

Review of Seagate Barracuda 7200.12 hard drive with 1000GB capacity

Seagate, known for its reliable hard drives, now manufactures hard drives that are eco-friendly in nature. Apart from capability and performance the 12-generation drives of barracuda family proved to consume power, creating environmental friendly systems. Seagate barracuda 7200.12 family consists of hard drives whose capacities range from 1000GB, 750GB, 500GB, 320GB, 250GB and 160GB. All these drives have their unique performance and ability to save power. This 7200.12 family hard drives offer performance, capacity and reliability with good combination. The pros and cons of Seagate barracuda 7200.12 hard drive with 1000GB capacity is reviewed in this article.

Specifications of barracuda 7200.12 1000GB hard drive:

The 7200.12 1000GB drive has a 3GB/s SATA interface with NCQ. It has a cache memory of 32MB and it has the ability to work with sustained data rate of 125MB/s. The maximum throughput rate of this barracuda can sustain up to 126 to 131MB/s, which makes this barracuda the first hard drive to achieve this speed with 1000GB capacity and spindle speed of 7200 rpm. The acoustic output of this drive is 2.5 bels and 2.7 bels during idle and seeks situations respectively. Combining all these specification, the barracuda 7200.12 1000GB delivers high performance than its rivals.

MCU Has High Speed, High Endurance, Low Power RAM Built-In

Fujitsu Semiconductor America, Inc. has launched a new 8 bit MCU for general-purpose applications, featuring Ferroelectric Random Access Memory (FRAM) embedded in a single-chip.

Specifications :

  • MCU – MB95R203A
  • Power Supply – 1.8Vmin – 3.6Vmax
  • Bus Width – 8 bits
  • FRAM Capacity – 8Kb Non-Volatile.
  • A/D Converter, UART, I2C, Timers, I/O Ports-16.
  • On-chip, One-pin debug.
  • On-chip, built-in Oscillator.
  • 20-Pin SOP or 24-Pin DIP Packages

Advantages :

By embedding FRAM within an MCU total cost and footprint has been reduced.  It will simplify system design. This architecture has eliminated the interconnections between MCU and external RAM and thereby significantly improved the transaction speed between MCU and the embedded memory, resulting in performance that exceeds Flash or EEPROM.

Project Lighthouse show way to Qt roadmap; reveal QML and commitment

The Nokia’s Director for Qt development, Lars Knoll gave a detailed description of the Qt plans at the Qt Developer Days conference. The development on a wider scale was driven by user needs such as web integration, 3D graphics, tactile feature supports and improved performance.

Qt Quick was also discussed in the conference. Knoll pointed out the role played by QML user interface language in Qt. Nokia uses Qt Quick to denote the QML and related technologies. The programming for the user interface is done in a finer pace to suit the developers. This could revolutionize the field of user interface developments and determine their future in Qt mobiles. Eventually, the development will have its effect on desktop and the way of the developers.

Qt Quick components strive to create pre designed user interface apps for QML and thus play a significant role in accelerating the growth of Qt Quick. QML Layouts can have an option to retain the original look on MeeGo as well as other OS plat forms. A newly devised debugger switches from QML to C++ and vice versa. It is currently under development. The QML tooling is to get a dynamic restructuring with such features. It allows the system to reload the layouts when an app is working simultaneously.
