Lego Mindstorms EV3 Hackable Robots Run Linux

The LEGO Group has announced LEGO MINDSTORMS EV3, a new platform for consumer robotics designed for both younger generation and robotics enthusiasts, at CES 2013. MINDSTORMS system is powered by the new EV3 Intelligent Brick, that comes with more memory (64 MB + 16 MB internal flash memory) and a faster processor (ARM9 @ 300MHz), and runs a Linux-based firmware. EV3 Intelligent Brick also features an infrared port, a 178×128 LCD interface, a USB host port and SD expansion slot, and is now compatible with iOS and Android for remote control via Bluetooth 2.1. Thanks to 6 buttons present on the EV3, users can now program many functions directly, in addition to the ability to download programs from a desktop computer. Lego claims a simple robot can be built in 20 minutes without having to plug it into a PC. Beside EV3 intelligent brick, the set comes with 550 Lego Technic […]

Piglit OpenGL Driver Testing Framework Now Works with ARM Linux & OpenGL ES

Piglit is a collection of automated tests for OpenGL implementations that aims at improving the quality of open source OpenGL drivers by providing developers with a simple means to perform regression tests. ARM SoCs that come with a GPU usually (always?) supports OpenGL ES however. That’s why, Tom Gall (Linaro) has modified Piglit in order to bring this test suite to ARM Linux and OpenGL ES. There are about 6,900 OpenGL tests in Piglit, and currently 1,047 Piglit (OpenGL ES) tests can run on ARM . Tom also explains that piglit developers are now using waffle, a cross-platform C library that allows one to defer selection of GL API and window system until runtime. This will allow your to select the variation of the GL API (GL, GL ES) and windowing system (X11, Wayland…) you want to use at runtime. The code is still heavily modified, but it’s in the […]

PowerUSB Computer Controlled Power Strips Review

PowerUSB power strips are four outlets power strips designed to help users save power by better understanding their devices power consumption, and automatizing tasks such as power on/off using timers, printer on/off controls, and more. One outlet is always on (for the main computer) and the 3 remaining outlets can be controlled via USB and the control software installed in a Linux, Mac or Windows x86 machine. The three of the four outlets are controlled through the software. Those power strips should allow lower electricity bills, and cover the cost of the strips ($69 to $129) within a few months. There are 4 models: PowerUSB Basic – $69.99 – The simplest model. You can control the 3 programmable outlets with on/off timers and keyboard shortcuts. PowerUSB Digital IO – $109.99 – This version adds 5 digital input/output lines for instrumentation and automation. The current model has 3 inputs and 2 […]

ZEALZ GK802 / HI802 mini PC Can Now Run Ubuntu 11.10

After Freescale made available i.MX6 development resources, we all knew this was a matter of time before Ubuntu runs on Hi802 / Zealz GK802 mini PC based on Freescale i.MX6. The guys at GeekBuying have done it, and a beta version of Ubuntu 11.10 can run on the Zealz GK802. This is not the first time Ubuntu or another Linux distributions can run on one of these mini PCs, but it’s the very first time we should get full hardware graphics and hardware video decoding in Linux. You may have noticed the screen is cut on the sides, that’s because they haven’t done overscan adjustment before shooting the video. They are using Ubuntu 11.10 (Linaro) because that’s the version released by Freescale that supports GPU and video acceleration, and if they used Ubuntu 12.04, it would not work until Freescale releases the proper drivers. However, scrolling does not seem particularly […]

$159 CuBox Pro: Open Source Development Platform Based on Marvell ARMADA SoC

Back in 2011, SolidRun unveiled the CuBox, a miniature open source development platform based on Marvell Armada 510 SoC (88AP510) and aimed at applications such as multimedia, set-top-box, network attached storage (NAS), thin client, digital signage, automation… SolidRun has now announced an upgraded version called CuBox Pro based on the same platform but with 2 GB RAM, and a redesigned casing. Here are the specifications of this development platform: Marvell Armada 510 SoC – 800 MHz dual issue ARM PJ4 processor, VFPv3, wmmx SIMD and 512KB L2 cache. 2GByte DDR3 at 800MHz 1080p Video Decode Engine OpenGL ES 2.0 graphic engine HDMI 1080p Output (with CEC function) Gigabit Ethernet, SPDIF (optical audio), eSata 3Gbps, 2xUSB 2.0, micro-SD, micro-USB (console) Standard Infra-red receiver for 38KHz based IR controllers. No JTAG required. Unbrickable for Developers (i.e. you can’t brick the device to the point you have to physically remove the flash, burn it […]

Smallart U-Host AllWinner A10 mini PC is Available for $20

Last July, I reviewed Smallart U-Host (U1A), an Android TV stick based on AllWinner A10 with 1GB RAM and 4GB RAM. At the time, I had a positive opinion of the device as the Android firmware was stable, and mostly did it was supposed, and it was feasible to run Linux distributions on the device. At that time, it was sold for $70, but this morning, Clint, one of my reader, informed me he spotted an AllWinner A10 device selling for $20.50 on Dealextreme. This device and the user interface resembles very much to Smallart U-Host, but the model name reported on Dealextreme is U2. According to Smallart U2 page, this device is based on Rockchip RK3066, so it’s just another naming mistake on DealExtreme. The rest of the specs are identical to Smallart U-Host: SoC – Allwinner A10 (Cortex A8) @ 1.5GHZ System Memory – 1GB DDR3 RAM Storage […]
