Product News Displays & UIs LED backlighting The revolution of low cost everyday 3-D printing arrives
OMC has released profiled LED back- lighting technology that is ideal for custom LCD glass modules. The technology ensures that very consistent illumination is provided across the entire display.
It is possible to feature single or dual chip LEDs depending on power output availability and requirements, and are available in full RGB and blue/white colours.
The company also now offers a fibre optic link service targeting the high voltage market. HV applications such as power distribution networks and power supplies often require optical isolation because of the voltages present however, achieving consistency of performance has proven a challenge for many providers. During manufacture of its housed optical transmitters (Tx) and receivers (Rx), OMC powers each active element and tunes the performance of the device to ensure that the electro-optical char- acteristics of each and every device fall within a customer-specific performance window, exactly matching the required performance specification.

The affordable 3-D printing revo- lution has arrived with a high- performance 3-D printer created by Belgian manufacturer Velleman. Available from reichelt elektronik, the printer comes complete with a kit that includes all the tools needed for assembly at no extra cost.
This solution is ideal for anyone who needs single copies or small lots of self-designed or obsolete objects – as this can now all be conveniently manufac- tured with a 3D printer. Objects can be printed down to the nanometer range. The Velleman K8200 uses Fused Filament
Fabrication (FFF) technology to create three-dimensional objects with a size of up to 20 by 20 by 20cm, either from PLA (polylac- tide) or ABS (acrylnitrile butadi- ene styrene). A very precise printed object is ensured by the heated printing plate Reichelt

Xmos makes beautiful music with Sony headphones
USB multicore microcontrollers from Xmos have been selected by Sony for its new PHA-2 portable headphone amplifier. The company’s xCORE-USB multicore microcontrollers will be used in the design of the Sony PHA-2. This device targets the current trend for high perform- ance but with a compact design
for portability uses multiple audiophile USB interfaces with a high resolution DAC and head- phone amp and is compatible with USB Audio Class 2 and DSD (Direct Stream Digital) technology; as a result this is said to provide a higher quality audio experience for listeners. The headphones can support music files with sample rates of up to 192kHz and full 24-bit res- olution, that is said to be on par with studio quality digital audio. With the rising demand for higher quality music from
portable devices, this range of microcontrollers is well equipped to meet these demands. They can be programmed to support a wide variety of streaming formats, including asynchronous data transfer that ensures jitter is removed. In addition to this, Xmos advises its solutions sup- port a range of source devices including PCs, portable music players, current and legacy Apple products, and common Android smartphones. XMOS
