Calxeda has released the results of ApacheBench benchmark comparing their ARM-based EnergyCore solution to an Intel Xeon server in order to showcase the performance and the much lower power consumption of their servers. Here’s the setup: Hardware: Single Calxeda EnergyCore ECX-1000 @ 1.1 GHz, 4 GB of DDR3L-1066 memory, 1Gb Ethernet network port and 250 GB SATA 7200rpm HDD Intel Xeon E3-1240 @ 3.3 GHz, 16 GB memory and 1Gb Ethernet network port. No info on hard drive provided Software: Ubuntu Server v12.04 Apache Server v2.4.2 ApacheBench v2.3 (16k request size) They performed power measurements every 2 seconds and averaged the results. Power supply overhead and hard drive power consumption were not excluded in the measurement, but the entire SoC and DDR memory power consumption were included together. For the Intel server however, they could not measure directly, so they used published TDP values for the CPU (80 W) and I/O […]
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 […]
MK802 Android 4.0 mini PC Factory Video
Nicolas Charbonnier, better known as charbax, has shot yet another cool video in one of the small factories where MK802 is assembled, showing the different steps they follow to build a complete device. The PCB assembly is probably done in another factory, and they just assemble the device in this factory, or I should probably call it a workshop… The place appears to be rather small and everything is done by hand, but that’s what makes the video very interesting. This is the company that sells it on Amazon under the brand “OEM Systems Company”. The first five minutes shows a tour of the factory, and in the rest of the video, Charbax interviews the sales manager and the owner of the factory who both dodge sensitive questions about pricing, BOM costs and quantities manufactured monthly… But hey, you’ve got to try. Jean-Luc Aufranc (CNXSoft)Jean-Luc started CNX Software in 2010 […]
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 […]
Deeper Smart FishFinder: A Sonar For Android and iOS Mobile Devices
Friday Lab has designed and developed Deeper Smart Fishfinder, a Sonar that communicates with your smartphone or tablet via Bluetooth in order to help you locate the best location for fishing (i.e. where the fish are…). Deeper works with Android 2.2 or greater devices as well as iPhones and iPADs running iOS 4.0 or greater. The device, about the size of a tennis ball, is made of high-impact polycarbonate shell. This smart sonar is waterproof and can handle small shocks. You can use the Deeper for up to 6 hours on a battery charge and Bluetooth range is up to 50 meters. You’ll be able to see the bed of the pond, lake or river on your device, know where and how big the fish are as well as the temperature and depth of water. You can watch the video to see how the device was designed and how it […]

Texas Instruments Launchpad MSP-EXP430G2 & Capacitive Touch Booster
This is a guest post about the low cost Launchpad MCU devkit. This kit was unveiled in 2010, but since I’d never written about this $4.30 development kit previously, I’ve accepted to publish the post below with slight modifications and amendments.
