Linux Conference Australia and FOSDEM 2013 Videos are Now Online

FOSDEM 2013 took place last week, and the organizers are in the process of uploading videos. Up to now, 5 main tracks sessions have been uploaded (Firefox OS;  Free, open, secure and convenient communications; FreedomBox 1.0;  Samba 4; and systemd, Two Years Later) as well as over 20 lightning talks. You can find the videos at http://video.fosdem.org/2013. You may also want to check my previous post for a lists of interesting talks, and I’ll probably feature some FOSDEM 2013 videos in this blog, at least the open source GPU driver talk. Linux Conference Australia took place on January 28 – February 1, 2013, and the 5-day conference featured lots of talks including several dealing with graphics in Linux, and one developer apparently trashing X in terms of complexity and performance, and explaining how Wayland was better. Others Linux sessions dealt with subject such as 3D printing, supercomputing, Arduino, big.LITTLE processing, […]

Review of Measy U2C Rockchip RK3066 Mini PC With Built-in Camera

I’ve received 2 new devices to play with this week, as Geekbuying sent me Tronsmart Promotheus set-top box and Measy U2C, a mini PC with a webcam, so that I can test and review them. Today, I’ll leave the “Spaceship” set-top box parked in another galaxy, and I will review Measy U2C mini PC. This HDMI dongle is powered by Rockchip RK3066, runs Android 4.1.1, and comes with 1 GB RAM, 8GB Flash, Wi-Fi & Bluetooth connectivity, and a built-in 2MP Webcam. For complete specs, you can check my post about B12 mini PC since this device uses the same board internally. Geekbuying sells this all-in-one mini PC for $74.99 including shipping. As usual, I’ll post some unboxing pictures, and then review the device, this time, with a section dedicated to the webcam, since this is the key selling point of this mini PC. Measy U2C Unboxing Measy U2C comes […]

Crazyflie Nano Quadcopter Open Source Development Kit

If you can’t wait until 2014 to get the MeCam, Seeedstudio has something for you: The Crazyflie Nano Quadcopter, which looks similar to the MeCam, but does not feature a camera, its control board is powered by STM32F103CB MCU @ 72 MHz with 128kb flash and 20kb RAM (so, no it won’t run Linux), and at $173 the price is significantly higher. Here are Crazyflie key features: Small and lightweight, around 19g and about 90mm motor to motor Flight time up to 7 minutes with standard 170mAh Li-Po battery Standard micro-USB connector for charging which takes ~20min for the stock 170mAh Li-Po battery On-board low-energy radio@1mW based on the nRF24L01+ chip. Up to 80m range (environment dependent) when using the Crazyradio 2.4 GHz USB dongle Radio bootloader which enabled wireless update of the firmware 32 bit Cortex M3 MCU: STM32F103CB @ 72 MHz (128kb flash, 20kb RAM) 3-axis high-performance MEMs […]

Replicate CAPE Adds 3D Printring Capability to the Beaglebone

Beagleboard.org launched the Beaglebone Cape Design Contest back in November, several designs were submitted, and yesterday, they announced the 3 winning CAPEs who will be manufactured and sold by Circuitco Electronics: Replicape by Elias Bakken – 3D printer cape Interacto by Chris Clark – Cape with a triple axis accelerometer,a gyroscope, a magnetometer and a 640×480 30fps camera. Geiger cape by Matt Ranostay – Geiger counter cape Since today I’ve started to write about 3D printing, let’s carry on and have a closer look at the Replicape. The Replicape 3D printer cape includes: 5 stepper motors (X, Y, Z, Ext1, Ext2) 3 high power MOSFETs (PWM controlled) for 2 extruders and 1 HPB 3 medium power MOSFETs (PWM controlled) for up to 3 fans 3 analog input ports for thermistors 3 inputs for end stops (X, Y, Z) Programmable current limits on steppers motor drivers (SMD). No need to manually adjust […]

3D Systems Cube and CubeX 3D Printers and Cubify Online Service

3D Systems was at CES 2013 to showcase their 3D printers, and their online 3D printing ecosystem called Cubify, where you can design your own model, order the object to be 3D printed, which is then shipped to your door. They have 2 printers that are available for the home market: Cube 3D printer ($1,399) Print size: 140 x 140 x 140 mm / Resolution: 200 microns CubeX 3D printer ($2,799 to $4,399) Print size: 275 mm x 265 mm x 240 mm / Resolution: 125 microns. The CubeX can support 1, 2, or 3 printer heads in order to print objects with multiple colors and/or materials. Charbax shot a video with the company, and I’ve learnt quite a few interesting things about 3D printing: It’s been around for nearly 30 years, but only used by the industry until recently. 3D printing takes a lot of time. The small spaceship […]

Raspberry Pi Now Has Experimental Support for VP6, VP8, MJPEG and Ogg Theora Video Codecs

The guys working on the Raspberry Pi (mainly dom) have added preliminary support for VP6, VP8, MJPEG, and Ogg Theora free video codecs, as well as Ogg Vorbis audio codec. Unlike H.264, MPEG-2 and VC1, those are not handled by the hardware video decoder in Broadcom BCM2835 processor, but are accelerated by the Videocore GPU. This means that only SD (and possibly 720p) videos are supported for those codecs. The best way to get support is probably to patiently wait for the Raspberry Pi foundation to release a new Raspbian image, but in case you couldn’t possibly wait, here are the steps to follow: Download and run Hexxeh’s rpi-update script in the Raspberry Pi in order to get the very latest build:

Add the following two lines to /boot/config.txt:

Reboot the Raspberry Pi The GPU firmware is now updated, but you still need the latest version of omxplayer. […]
