BlackBerry PlayBook 4G LTE hands-on

BlackBerry PlayBook 4G LTE handson

RIM’s attempts to get a cellular-equipped version of the BlackBerry PlayBook have been troubled, to say the least. The company signalled its intentions around Mobile World Congress last February, only to watch as carriers backed off — partly as RIM focused its attention on LTE, and partly after carriers grew skittish over sales of the WiFi version. A year and a half later, we finally have an LTE version, and with a faster 1.5GHz processor to boot. But do 4G data and a processor bump make all the difference? And does the upgrade stand a realistic shot in a competitive field that has moved on since the original PlayBook? We’ll find out in our hands-on.

New TI power chips save energy, move towards universal charging

New TI power chips save energy, move towards universal charging

TI isn’t just in the business of making ARM-based processors. The company makes all manner of components and chips. Amongst the things in its vast repertoire of silicon are charging controllers. Texas Instruments’ latest offering, the UCC28700, not only draws an impressively low sub-30mW when idle (meeting new five-star rating requirements from the European Commission), but does so in a tiny package that eliminates the need for an opto-feedback circuit or other external components. A second new controller, the TPS2511, tackles the problem of multiple chargers by moving to a 5V universal system for tablets and smartphones using the USB Battery Charging 1.2 specification. This could mean not only lower electricity bills (if only nominally so), but smaller wall warts that can be used across numerous devices. For more, check out the PR after the break.

Microsoft to Windows RT OEMs: ‘If your name’s not on the list, you’re not making a tablet’

Image

China Times is reporting that Microsoft is only letting an elite few companies build Windows RT tablets in order to focus its research and development resources. It reportedly asked three chipmakers to pick up to two OEMs to bring inside the tent, with NVIDIA grabbing ASUS and Lenovo, TI snagging Toshiba and Qualcomm selecting Samsung and HP. However, the latter company dropped out of the program to concentrate on x86 machines, so it’s rumored that Dell’s currently jockeying to take its place. The first wave of completed tablets will arrive on October 26th, and Redmond won’t open up the market until January next year — so expect Windows RT to be the buzz-word CES 2013.

Naked scanners zoom on your teeth in TI research

The same technology that allows airport staff to laugh at your genitals could soon allow dentists to check your wisdom teeth without first irradiating you with X-rays. Silicon-based terahertz range emitters and detectors, however, could shrink the airport scanner tech down to 45nm CMOS scale, according to research at the Texas Analog Center of Excellence at the University of Dallas, EETimes reports. In collaboration with Texas Instruments, they’ve come up with an on-chip antenna that could eventually find its way into a compact X-ray alternative machine suitable for medical professionals.

Causing headaches – metaphorically – so far has been sufficiently stabilizing the frequency of the terahertz waves, with TI and the Dallas team building on research funded earlier in 2012 by Semiconductor Research Corp. into CMOS detectors. TI uses a phase-locked loop to stabilize at around the 390GHz point, “the highest frequency ever demonstrated for a phase-locked loop” according to TI design engineer Brian Ginsburg.

Future iterations will see that number climb, however, with targets of 600GHz or higher for TI’s 45nm processes. Boosting the output power is also on the agenda, with the current prototype mustering 2.2 microWatts.

As well as the health benefits from reducing potentially cancer-causing X-ray exposure, terahertz alternatives could also be more flexible in how they are implemented. Optical components such as lenses could be used to reflect and direct the waves, potentially making for more compact equipment.

Miselu Neiro synth at Google I/O: exclusive first look at apps from Korg and Yamaha (video)

Miselu Neiro synth at Google I/O: exclusive first look at apps from Korg and Yamaha

Remember Miselu’s Neiro — that prototype app-based Android-powered synth we last played with at SXSW? Not only is it being showcased at Google I/O 2012 here in San Francisco, but we got an exclusive first look at some of the apps being developed for the new platform ahead of the event. The company’s been on a roll since our meeting in Austin, gaining (ex-OQO CEO) Jory Bell as CTO and building relationships with partners like Korg and Yamaha.

Now on its second iteration, the laptop-like synth has evolved from the hand-built prototype we saw at SXSW to a more polished reference design — complete with breakout board for SD card and Ethernet support. As before, the device runs Gingerbread on a dual-core TI OMAP processor and features a two octave velocity and pressure-sensitive keyboard, a capacitive multitouch widescreen, WiFi and Bluetooth connectivity, audio and MIDI I/O, plus USB and HDMI ports. This version even adds XLR and quarter-inch audio jacks — just keep in mind that those specs have not been finalized.

What’s really exciting about the synth is the apps. The company’s ongoing partnership with Retronyms to create a suite of touch-controlled, cloud-enabled musical apps has evolved beyond the drum-machine demo we covered at SXSW. Called nStudio, the suite now also includes a pad-based sampler / sequencer and a mixer. Plasma Sound is a touch-based musical instrument that’s part theremin, part keyboard / sequencer. It’s already available for other devices on Google Play, but was easily tweaked to run on the Neiro — sight unseen — thanks to Miselu’s musicSDK and OS X-based emulator.

Miselu will be showcasing two more apps on its synth here at Google I/O: Korg’s Polysix and Yamaha’s Vocaloid. The Polysix app fainthfully recreates Korg’s legendary 1981 synth — known for its rich, thick analog sound. A real, mint-condition Polysix was even available for comparison during our brief time with the app (see our gallery). Vocaloid takes full advantage of the NSX-1 DSP chip that’s built-into the Neiro. It’s a singing synth app produced by Yamaha that “uses concatenative synthesis to splice and process vocal fragments extracted from human voice samples.”

We’ll be spending some time with the Vocaloid app and its creator — video game designer Tetsuya Mizuguchi (of Sega and Lumines fame) — later today. In the meantime, check out the gallery below and watch our hands-on video with the other apps after the break.
