Opendive – Low Cost DIY Open Source 3D Virtual Reality Kit for Smartphones

About 10 days ago, I wrote about solution to record and play 360 degrees panoramic videos. One of the itmen was vrAse virtual reality case for your smartphone, and allows you to enjoy immersive 3D experience. If you’d rather do your own, than buy a kit for about 100 Euros, there’s an open source project called OpenDive that does about the same thing, and allows you to play games in 3D. All you need to do is to download the 3D files, print the head-mounted glasses it with your 3D printer, and buy the lense kit (6.99 Euros) to get a complete working system. You may have to modify the design, and adapt it to your phone dimensions. And if you don’t have a 3D printer, somebody provided instructions to do your own by cutting wood or plastic sheets. You then should be able to watch 360 deg. panorama videos, and […]

Selecting the Best Adobe Flash Player in Linux for x86 and ARM

I’ve had countless and recurrent crashes caused by Adobe flash plugin either in Firefox and Chromium, mainly while playing videos from YouTube or other online video services that still mostly use flash, instead of HTML5. Adobe flash death is certain, but up to now it has been soooo slow, so I doubt that thing will truly die any time soon, and unfortunately it will probably be with us for many years to come. To work around the issue, I started by enabling Youtube HTML5 player, and try to play embedded videos inside YouTube instead of the orignal website. I still had crashes from time to time, and this method did not help with other video services. So I decided to check out what I could do to fix the issue. When you go to http://www.adobe.com/software/flash/about/ you can check your flash version, and Adobe will also list the player version for […]

Mediatek Hotknot is a Low Cost Alternative to NFC for Chinese Phones

NFC first started to be found in phones running Android 2.3 in 2010, and most flagship smartphones integrate NFC. But in China, at least, the story is different with about 10 percent of smartphones enabled with NFC, according to Mediatek. That’s partly why the company has designed Hotknot proximity technology, which is in theory capable of anything NFC does, but comes at a lower cost. Contrary to NFC, Hotknot it does not require RF transceiver and antenna, but instead relies on a new type of capacitor touch driver IC designed for touch screens combined with data from a gravity sensor (G-sensor) to ensures the actual contact, and a proximity sensor (P-sensor) to detects the presence of nearby objects. It’s not clear when the first smartphone with the technology will hit the “e-store”, but HaoJung Li, product marketing manager of MediaTek’s wireless communications business unit, told EETimes, that every MediaTek customer, […]

Mali-400 GPU Is Now Working in Linux for Rockchip RK3188 Devices

Accelerated 3D graphics in Linux with Mali-400 via OpenGL ES has been possible for nearly a year on RK3066 devices, but there was no such support for RK3188. This week however, both Naoki FUKAUMI and omegamoon have reported OpenGL ES to work in in their respective RK3188 devices. I don’t know which device omegamoon used, but Naoki did so in Radxa Rock, and even posted instructions to build it yourself. They’ve mostly followed the work done by olegk0 for Rockchip, and Mali drivers build instructions provided in linux-sunxi community, and it can be summarize in 3 main steps: Cross-compile drm.ko, mali_drm.ko, ump.ko, mali.ko in a Linux machine Copy and load the four modules to your RK3188 based board or device. Install dependencies and binary Mali drivers from sunxi-linux in your Rockchip device Once this is done you can try some OpenGL ES demos such as esgears2 or glmark2-es to test […]

AAEON EMB-KB1 AMD G-Series SoC based mini-ITX Embedded Motherboard

AMD announced their G-Series SoC combining CPU, GPU and chipset in a single chip nearly a year ago, but AAEON EMB-KB1 is the first mini-ITX board I’ve ever heard of using these embedded SoCs. The board features first generation AMD SoCs in dual and quad core configuration, with up to 16GB RAM, up to 9 USB interfaces, 2 SATA III ports, and 2 USB 3.0 ports. AAEON EMB-KB1 hardware specifications: SoC GX-420CA quad-core CPU @2.0GHz with AMD Radeon HD 8400E GPU @600MHz – 25W TDP GX-217GA dual-core CPU @1.65GHz with AMD Radeon HD 8280E GPU @450MHz – 15W TDP System Memory – 2x SODIMM sockets for up to 16GB DDR3/DDR3L @ 1600MHz/1333MHz Storage – 2x SATA III (6.0Gb/s) I/O Chipset – Fintek F8186D-I Connectivity – 2x Gigabit Ethernet (Realtek 8111F) Video Output – 1x LVDS, 1x VGA, and 1x DVI up to 1080p or 1920×1200 Audio – Mic-in, line-out, and […]

Mediatek MT6589 Linux Source Code, CyanogenMod 11 Image for Wiko Stairway Smartphone

Mediatek and their customers have still not gotten into the habit of complying with the GPL license, and releasing the relevant source code such as the Linux kernel. There appears to be at least one smartphone, Wiko Stairway, where the Linux kernel has been released, and chrmhoffmann, a members of XDA developers forums, has even released on unofficial CyanogenMod 11 ROM (Android 4.4.2 Kit Kat) for the device. There are three source repositories for the Linux kernel, “android device“, and Android. I’ve only looked into the kernel which is version 3.4.5. Mediatek has apparently messed up the Linux kernel quite a bit, and you’ll have to do some funny things to build the kernel, and all Mediatek options in menuconfig are in a sub-section called “Mediatek Properitary Configuration” (sic.), and it’s not possible to simply go to System Type menu to change the processor type for instance. Let’s get the […]

$120 Raspberry Pi Bundle with LCD Display, Expansion Boards, Cables, and Accessories

Yesterday, Element14 has announced Wolfson Audio Card for the Raspberry Pi which adds multiple audio inputs and outputs to the low cost ARM Linux board, as it has been widely reported in the blogosphere. I’ve just mentioned it in case you missed it, as instead I’m going to write about a bundle with the Raspberry Pi Model B, lots of expansion boards, cables, and accessories such as a power supply, or a remote control that can be purchased for $120. It may not be useful if you only have a specific project in mind, but if you want to play around and interface with lots of different hardware, or even offer electronics lessons, it could be interesting. The complete kit includes: Raspberry Pi Model B with 512 MB RAM. Acrylic Case for RPi (not shown above) Expansions boards and modules: DVK511 Expansion Board with headers, jumpers, LEDs, and potentiometer 2.2″ […]
