Always Innovating MeCam is a $49 Voice-Controlled Nanocopter Camera

Earlier today, I’ve posted a list of some interesting sessions for the upcoming ELC 2013, and one of the talk entitled “Lessons Learned in Designing a Self-video Self-hovering Nano Copter” by Gregoire Gentil, Always Innovating CEO, caught my attention. In this presentation, he will talk about the technical challenges the company encountered when they designed MeCam, a self video nano copter to point-and-shoot yourself, that should sell for just $49 retail. The MeCam launches from the palm of a hand and hovers instantly. It streams video to an Android or iOS phone or tablet that can be easily shared on social media platforms such as YouTube, Facebook, Google+ and Twitter. There’s no remote control for the MeCam as it’s either controlled by voice commands, or it can be setup to follow you around thanks to the follow-me feature. It can also do panorama shots automatically. The products is still in […]

$199 Gizmo Explorer Kit Powered by AMD G-Series APU is Now Officially Available

Back in November, I came across the Gizmo Explorer Kit, an embedded development platform based on AMD G-Series G-T40E dual core APU that includes the development board itself (Gizmo Board), two expansion I/O boards, Sage SmartProbe JTAG development tool, some accessories such as cables and power supply, and a DVD with the documentation and SDK. Today, Sage Electronic, Texas Multicore Technologies, and Viosoft officially launched GizmoSphere community that aims at “fostering innovation and development for x86-based embedded Accelerated Processing Units (APUs), and driving and enabling technology projects of interest to independent developers with a focus on stimulating and encouraging innovation for existing and new applications that leverage APUs”. To help with this initiative, they also produce the Gizmo Board, and corresponding Gizmo Explorer Kit, a development board that boots with coreboot, and can run a variety of operating systems such as Android, Linux, Windows, and other RTOS. You can refer to […]

Embedded Linux Conference 2013 Schedule

The Embedded Linux Conference (ELC 2013) will take place on February 20 – 22, 2013 at Park 55 Hotel in San Francisco, California. ELC consists of 3 days of presentations, tutorials and sessions. There will be over 50 sessions during those 3 days. I’ll highlight a few sessions that I find particularly interesting, and that did not get presented at ELCE 2012 (AFAICR). February 20 11:00 – Anatomy of the arm-soc git tree by Olof Johansson, Google We are now two years into the new maintainer model for ARM platforms, and we have settled down into a workflow that maintainers have adjusted well to. Still, when new platforms arrive, or when maintainer ship changes hands, there’s sometimes a bit of ramp-up in getting used to how we organize our git tree and how we prefer to see code submitted to fit that model. This presentation will give an overview of […]

How to Access the Serial Console in HI802 / GK802 mini PC

One of the advantage of HiAPad Hi802 (aka Zealz GK802) is that it provides access to UART and I2C pins via through holes on the board. UART4 Tx and Rx pins give you access to the serial console which is a must for bootloader (U-boot), and kernel development or for debugging. The first thing is the open the casing and locate the debug pins on the board. The very best way is probably to solder a pin header, but since I don’t have header, nor soldering iron, I’ve done it the “MacGyver” way with 3 wires connected to TxD, RxD and GND, and some sticky tape. You can now insert the other side of the wires into your USB to TLL debug board (GND <-> GND, Tx <-> Rx, and Rx <-> Tx), and connect it to your Windows or Linux PC. The serial board should be recognized as a […]

LTSI 3.4 is Now Available for Download

Nearly 2 years ago, the Linux Foundation’s Consumer Electronics (CE) working group created the Long Term Support Initiative (LTSI) Linux kernel for consumer electronics devices in order to have a common stable platform released every 2 years, and share the kernel development work among competing companies including Hitachi, LG Electronics, NEC, Panasonic, Qualcomm Atheros, Renesas Electronics Corporation, Samsung Electronics, Sony and Toshiba. Last week, the CE working group has released LTSI 3.4 kernel, based on Linux 3.4.25 kernel release and including several backported features from newer kernels including: The Contiguous Memory Allocator (CMA), which is extremely useful for embedded devices that have very limited hardware resources and will better handle the large memory requirements of multimedia applications. CMA originally was merged into the 3.4.0 kernel release, but its functionality was quite limited. Since then, the feature has been significantly improved in the kernel.org releases and those fixes have been added to […]

PicUntu – Rockchip RK3066 Linux Distribution for mini PCs (UG802, MK808, …)

Many people are using RK3066 mini PCs because they currently offer the best performance to cost ratio, but until now they were mainly limited to Android Jelly Bean, although there was some preliminary port of Ubuntu available for the devices. Now, this preliminary port has become a specific Linux distribution for Rockchip RK3066 PCs-on-a-stick called PicUntu, which is based on Ubuntu 12.10, and can optionally support Xfce or Gnome desktop environments. This distribution is known to work on UG802 and MK808, but should also work on some other RK3066 mini PCs such as iMito MX1. The latest version is Picuntu 0.9 RC 2.2, and features such as WiFi, Ethernet, HDMI audio, USB webcam are known to work, What you won’t get, however, is hardware video decoding and GPU support since Rockchip does not provide the relevant binary files for Linux, but this does not seem to stop the developers from […]

GPUs Comparison: ARM Mali vs Vivante GCxxx vs PowerVR SGX vs Nvidia Geforce ULP

I’m always very confused when it comes to comparing GPUs in different SoCs, and I could not really find comparisons on the web, so I’m going to give it a try even though, as you’re going to find out, it’s actually quite a challenge. There are mainly 4 companies that provide GPUs: ARM, Imagination Technologies, Vivante and Nvidia. [Update: Two comments mentioned Qualcomm Adreno and Broadcom VideoCore are missing from the list. Maybe I’ll do an update later]. Each company offers many different versions and flavors of their GPU as summarized below. ARM Imagination Technologies Vivante Nvidia Mali-400 Series: Mali-400 MP Mali-450 MP Mali-600 Series Mali-T604 Mali-T624 Mali-T628 Mali-T658 Mali-T678 PowerVR SGX Series 5: SGX520 SGX530 SGX531 SGX535 SGX540 SGX545 PowerVR SGX Series 5XT: SGX543MP1-16 SGX544MP1-16 SGX554MP1-16 PowerVR SGX Series 6: G6200 G6230 G6400 G6430 G6600 2D graphics: GC300 GC350 3D graphics: GC400 GC800 GC1000 GC2000 GC4000 ULP GeForce (Tegra […]
