This Multi-function Capacitive Stylus Includes a USB Flash Drive

April 1st, 2015 No comments

If you have fat fingers, or somehow capacitive touchs creens don’t work that well with your fingers, or you simply need more accuracy, you may have purchased one of those cheap capacitive stylus, many of which come with a real ball-point pen and/or a flash light. However, I’ve just noticed GeekBuying listed a few USB multi-functional 6-in-1 touch pens with 4 to 32GB internal flash with prices ranging from 8 to 19 dollars. Based on the picture above, you can open the stylus to take out a USB flash drive that you can insert into your computer, laptop or mobile’s micro USB OTG port via an OTG adapter. Specifications include: Use with touchscreen of smartphone or tablet PC Ball-point pen Files storage (USB flash drive) Money inspection (ultra-violet light) Pointer (red laser) Mini flash-light Dimensions – 143 x 12 mm Weight – 25 grams I find the USB drive-in-a-pen idea pretty neat, although I’ve found out it’s not exactly new….

Cubieboard 4 Ubuntu Review – Setup, Usability, and Performance

April 1st, 2015 No comments

Cubieboard4 is a development board powered by Allwinner A80 octa-core processor with 2GB RAM and 16GB eMMC. I’ve already shown how to get started with the board using the pre-installed Android 4.4 image, and run some benchmarks in Android, so now it’s time to check out the Ubuntu Linaro 14.04 image provided by CubieTech. I’ll show how to install and setup Ubuntu 14.04 on the board using a micro SD card, run desktop applications like Chromium, Libre Office, and son on on the board, and complete the review with some Linux benchmarks. Setting up Ubuntu on Cubieboard4 Firmware images for Cubiebord4 can be downloaded @ http://dl.cubieboard.org/model/cc-a80/Image/. Currently Android 4.4, Debian server, Ubuntu Linaro server, and Ubuntu Linaro desktop with LXDE desktop environment. That’s the latter I’ll use for the experiment, and two images are available: linaro-desktop-cb4-card-hdmi-v0.4.img.7z – Bootable image from micro SD card linaro-desktop-cb4-emmc-hdmi-v0.4.img.7z – Installation image to eMMC to be written to micro SD card (and not via PhoenixSuite)….

How to Read OpenOffice / LibreOffice Files from the Command Line

April 1st, 2015 No comments

Let’s say you have edited a file in LibreOffice Writer, but later you access your computer remotely via SSH for example. You don’t really want to bother copying the file to your current machine, and rather just quickly check its content in the terminal. Is there a way? Since odt files are just some zip files containing XML files, you could manually decompress the file, and open XML files, but there is a more convenient the program is called odt2txt. On an Ubuntu / Debian machine it can be installed with: sudo apt-get install odt2txt For basic usage, you just need to pass the filename as parameter: odt2txt test.odt This is a test But there are also a few more options: odt2txt odt2txt 0.4 Converts an OpenDocument or OpenOffice.org XML File to raw text. Syntax: odt2txt [options] filename Options: –raw Print raw XML –encoding=X Do not try to autodetect the terminal encoding, but convert the document to encoding X unconditionally…

Asus Chromebit Chrome OS TV Stick to Sell for Less than $100

April 1st, 2015 No comments

Google has just announced Rockchip RK3288 Chromebooks, and also quickly mentioned Chrombit Chrome OS dongle, but with very few details. However, several large US blogs like Engadget and Gizmodo got a sample (mock-up?), and shared more details. So now we have the technical specifications of the dongle, which unsurprisingly also feature RK3288 processor: SoC – Rockchip RK3288-C quad core Cortex A17 processor with ARM Mali-T764 GPU. System Memory – 2 GB DDR3L SDRAM Storage – 16 GB eMMC Flash Storage Video Output – HDMI Connectivity – Dual band Wi-Fi 802.11 2×2 (MIMO) a/b/g/n/ac, Bluetooth 4.0 USB – 1x USB 2.0 host port, 1x micro USB OTG port Power – 5V via micro USB port Dimensions – N/A Weight – N/A It’s quite likely the Rockchip processor won’t run at full speed, at least not for a long period of time, as it’s likely to overheat in such small form factor, but for most use cases it should not be noticeable….

Intel Introduces Celeron N3000 / N3050 / N3150 and Pentium N3700 Low Power Braswell Processors

April 1st, 2015 No comments

Intel Bay Trail processor are found in low cost tablets, laptops and mini PCs with prices starting as low as $60 for retail products. The company has introduced Braswell some time ago, the successor of Bay Trail, which among other thigns brings 14nm process technology instead of 22nm, for even lower power consumption. CPU World has noticed Intel listed the first four low power Braswell processor using Celeron and Pentium branding and with 6W TDP max. We only know a few details about the new processor Celeron N3000 – Dual core CPU @ 1.04 GHz (Burst: 2.08 GHz) with 1MB L2 cache, 4W TDP Celeron N3050 – Dual core CPU  @ 1.6 GHz (Burst: 2.16 GHz) with 1MB L2 cache, 6W TDP Celeron N3150 – Quad-core CPU @ 1.6 GHz (Burst: 2.08 GHz) with 2MB L2 cache, 6W TDP Pentium N3700 – Quad-core CPU @ 1.6 GHz (Burst: 2.40 GHz) with 2MB L2 cache, 6W TDP All four processor come…

Onion Omega is an Atheros AR9331 Wi-Fi Module Supporting Various Docks and Add-on Boards (Crowdfunding)

March 31st, 2015 No comments

There are so many inexpensive Wi-Fi modules running Linux that it would be easy to discard Onion Omega as yet another Wi-Fi module based on Atheros AR9331 WiSoC. However, the developers have tried to bring some added value by making programming easier for web developers, integrating it with a cloud platform (free for non-commercial use), and providing basicor Arduino dock, and add-on boards for Ethernet, OLED, Relay… to make building hardware projects easier too. Let’s go through the hardware first, starting with the module specifications: SoC –  Atheros AR9331 400MHZ MIPS 24K System Memory – 64MB DDR2 400MHz Storage – 16MB Flash Connectivity – 10/100 Mbps Ethernet + 802.11b/g/n Wi-Fi up to 150Mbps with PCB antenna w/ uFL connector I/Os –  18 GPIOs USB – 1x USB 2.0 Power Supply – 3.3V; Typ. consumption: 0.6W Dimensions – 28.2mm x 52mm (1.1″ x 2.0″) Since this type of module is not always convenient to use standalone… three docks have been designed:…
