Baanto ShadowSense Technology Enables Virtual Graffiti Drawings on Multitouch Displays

Baanto ShadowSense is a new 2D and 3D tracking technology using sensors that allow the system to determine the relative angle and as well as other characteristics of the shadow cast by an object. The system is provided as a frame with several sensors (4 typically) that you can connect via USB to your computer. It is an USB HID device, does not need drivers and support Windows XP/7, Linux and Android. This proprietary technology has the following key features: Traceability of multiple points or objects simultaneously (up to 5 points) Up to 10,000 fps. 16 MPixel resolution of shadow position. Simple algorithm that can be implement in 8-bit MCU. Low power draw. Less than $10 US per sensor. A typical configuration uses 4 sensors and plenty of small LED emitters as shown the illustration. Up to 1mm resolution of object position. No optical lenses are required The resolution is […]

AMD Introduces AMD G-T16R G-Series APU with 2.3 Watts Power Consumption

AMD has unveiled another APU in its Embedded G-Series processor family with the AMD Embedded G-T16R, which aims to provide a more powerful (up to 3x) and less power-hungry (7% less) replacement to AMD Geode LX processors. The AMD G-T16R is targeted at very low power, small form factor and cost-sensitive embedded designs. The company claims the processor consumes about 2.3 watts on average or 4.5 watts thermal design power (TDP). This new AMD embedded processor targets industrial control, point-of-sale, medical appliance and transportation markets.  As with the other G-Series platforms, the G-T16R can fit into small form factor boards by implementing a two-chip platform: APU + controller hub. AMD G-T16R is clocked at 615MHz, features a Radeon HD 6250 GPU and supports 1920×1200 resolution via VGA, single link DVI and DisplayPort 1.1a video outputs. It can also output 1080p via HDMI and LVDS. The APU supports Windows Embedded Compact […]

Oval Elephant Android / Linaro mini PC HDMI Stick

Since Rikomagic MK802 and Zero Device Z802 mini PCs have gone viral and started the Android mini PC craze, this type of device has been popping a bit everywhere… The latest interesting device I found is Oval Elephant Mini PC based on AllWinner A10 processor with 1 GB RAM and selling for 71.49 USD. They have appears to have a whooping 11 in stocks now to be shipped on the 3rd of July, but they are also taking pre-orders and if there is enough demand (over 1,000 pieces), the price would go down to 68 USD. The device pictured above is just a prototype, and they have decided to replace the HDMI mini male output by a proper HDMI output (probably male). As I said before I prefer this form factor, especially since you can just connect mini BlueTooth dongles (no sure that one works with Android / Linux though) to […]

Migrating a WordPress Blog from Apache2 to Nginx

This blog is hosted on a Linode VPS with 512 MB RAM and running Ubuntu 11.10. Up until today, Apache2 was the web server, and it worked fine except sometimes, it reached connection and memory limits, and the blog would go offline for a short period of time, especially right after a new blog post. So this week-end, I decided to switch to nginx (pronounced engine-x) web server which is said to use less memory than Apache2. Let me know if something suddenly stopped working… nginx is a relatively recent web server, and the documentation on the web seems to become outdated pretty fast, so I’ve decided to document what I’ve done. The first thing I would recommend is to try it in your own local server first,  and make sure most things are working including plugins. Testing your WordPress blog with nginx in a local server I run Ubuntu […]

VIA Announces ARM Cortex A9 Based Digital Signage System

VIA has unveiled its ARM Digital Signage (DS) system for cost sensitive high volume digital signage deployments. The system is based on an unnamed Cortex A9 processor (possibly Wondermedia WM8850?) with up to 2 GB RAM and 64 GB Flash. The company expects the device to be used in a wide range of applications such as kiosks, POS systems, video walls, menu boards to TVOIP, cloud streaming, and Out of Home Advertising. Here are the specs of this digital signage player: All in one system-ready to load software Designed for Android operating system Industry standard ARM Cortex A9 SoC Hardware acceleration of the most demanding video formats for resolutions up to 1080p DVI-D display port (HDMI Optional) 4x USB 2.0 ports 10/100 Ethernet port Audio-out/ Mic-in Up to 64GB NAND Flash Up to 2GB DDR3 SDRAM Dimension – 18 cm x 12 cm x 2.5 cm The VIA ARM DS […]

Freescale Announces Availability of Kinetis L Series Cortex M0+ MCU and Freedom Devkit

ARM unveiled its ultra-low power Cortex-M0+ core back in March, and Freescale and NXP also announced their plans to use this new core in some of their micro-controllers destined to power the internet of things. Yesterday at Freescale Technology Forum (FTF), Freescale announced the availability of alpha samples of its Kinetis L series. This new low power MCU family will allow existing 8-bit and 16-bit architecture to be replaced by 32-bit architecture without increasing power consumption, cost or size, and the company expects them to be used in devices such as small appliances, gaming accessories, portable medical systems, audio systems, smart meters, lighting and power control. The ARM Cortex-M0+ processor is said to consume about a third of the energy of any 8- or 16-bit processor, while delivering between two to 40 times more performance. Kinetis L series MCU  can consume as low as 50 uA/MHz in very-low-power run (VLPR) […]

Getting Started with Emcraft Systems Cortex M3/M4 Starter Kits Running uCLinux

A few months ago, I wrote a post about running uCLinux on Cortex M3/M4. Since then I’ve had the opportunity to play a with Cortex M3  & M4 boards capable of running Linux, as last week, I received Emcraft Systems Freescale K70 Starter Kit together with their MicroSemi (previously known as Actel) Smartfusion SoM. Today, I’ll show some pictures of the baseboard and modules I received in the kit, and some details about the documentation and how to get started with the modules. Unboxing Pictures Here’s the baseboard with Ethernet, USB interface using USB-UART bridge connected to the UART0, JTAG connectors (P3 and P5), two push-buttons and a breadboard for easy access to unused signals (ADC, I2C, SPI, UART and GPIOs). P4 and P6 are the sockets to plug in the SoM. There is a lithium-ion battery (CR2016) at the back of the board for the RTC clock. As previously […]

WM8850-MID Android 4.0 Tablet Unboxing and Review

I recently bought an Android 4.0 tablet with a 7″ capacitive touchscreen based on the new WonderMedia WM8850 processor (Cortex A9 + Mali-400). In my first post, I called this tablet UGoos UG-LMW70, but I just received a no brand package with nothing mentioning Ugoos or the model number UG-LMW70 anywhere. Android settings just show WW8850-mid for the model number. The tablet comes with a 5V power supply, a miniUSB to USB cable, a short miniUSB to USB female adapter, headphones and a user manual in English explaining how to use Android, but nothing about the tablet itself. The tablet has vol-/+ buttons and a power button (left side below), and a power jack, microSD slot, headphones jack, a USB host port, a mini HDMI port, a miniUSB port and a microphone (right to left). They did not include a mini HDMI to HDMI cable, so I did not try HDMI […]
