Texas Instruments SensorTag Unboxing, Getting Started with Bluetooth Low Energy in Linux (with a Raspberry Pi)

Texas Instruments CC2541 SensorTag is a Bluetooth Low Energy (BLE) development kit with 6 sensors (IR temperature, humidity, pressure, accelerometer, gyroscope, magnetometer) mainly destined at mobile application developers for iOS, and soon, Android 4.3. I’m interested in BLE, as I expect most new phones with come with BT 4.0 BLE (aka Bluetooth SMART), and this technology may help bring the Internet of things to life, allowing us to interact with sensors, smart appliance (e.g. light switch)… Since it just costs $25 (including international shipping), I decided to buy it, and give it a try. Today, I’ll show some unboxing pictures, and how to communicate with the kit using the Linux command line. TI SensorTag Unboxing I ordered it at the end of May, and receive it by Fedex on the 18th of July, about 7 weeks later, in the package below. Inside we’ve got a Quick Start Guide for iOS […]

WigWag Simplifies Home Automation, Provides Raspberry Pi and Arduino Shields

WigWag is an home automation kit aiming at simplifying home automation, yet allowing developers to roll their own system via Arduino and Raspberry Pi Shields. Wigwag is currently composed of three devices: WigWag Sensor Block – Universal sensor device with 8 environmental sensors (light, detect motion, sound, temperature, humidity, movement…), 4 control features (relay, IR blaster…), and 2 expansion ports. It can be powered by 4x AA batteries (possibly for up to 1 year), or a USB power adapter. This device runs Contiki OS on Freescale MC1322 MCU (with built-in 6LoWPAN radio). WigWag Relay – Connects WigWag and third party devices to their cloud service, allowing interaction with Internet services, such as email, Dropbox and Twitter. It acts a bit like a central server managing all your WigWag Sensor Blocks or other connected devices such as Phillips Hue light bulbs or Belkin WeMo outlets in your house. IP networks (Wi-Fi & Ethernet) […]

Risun D05 is an Android TV Stick Powered by Rockchip RK3068 SoC

I’ve just discovered another dual core Rockchip SoC called RK3068, but it may not be new, as I can find some references as far back as September 2012. Amazingly, I can’t seem to find any announcement, and details are scarce. Very few products feature this chipset, but Risun D05, an Android mini PC, is one of them, so let’s have a closer look. Risun D05 specifications based on Alibaba listing: SoC- Rockchip RK3068 dual core ARM Cortex A9 @ 1.6 GHz with dual core Mali-400 GPU System Memory – 1 GB DDR3 Storage –  4 GB NAND Flash, with option for 8GB or 16GB, + micro SD card slot (Up to 32GB) Video Output – HDMI 1.4 male Video Codecs – MPEG 1, MPEG-2, MPEG 4,H.263, H.264, AVS, VC 1, RV, VP6 VP8, Sorenson Spark, MVC 1920x1080P 60FPS. Video Encoder – H.264,VP8,MVC(1080P) Audio Formats – MP1, MP2, MP3, WMA, WAV, OGG, […]

Lernstift Digital Pen Hits Kickstarter for $150

Lernstift is a digital pen running Linux that aims at helping children learning how to write by vibrating when they’ve made calligraphy or orthography errors. I’ve covered the overall concept in an earlier post, which you can read for details. The company has made some progress, and they have just launched a kickstarter campaign where you can pledge 99 GBP (about $150) to receive the pen later this year or in early 2014. We do know a little more technical details. The first prototype was based on Gumstix Overo (TI OMAP3 or Sitara), but they are now working to design a custom board based on the platform for the final design. The pen comes with 128 MB RAM and runs embedded Linux. In order to gather handwriting data, Lernstift leverages a motion sensor that combines gyroscope with accelerometer, and adds a magnetometer. They’ve got a drawing with Freescale MMA9950L, but […]

Hacking MK908 mini PC for Serial Console Access

Thanks to Omegamoon (and this brother) we already have instructions to connect the UART pins on MK808 in order to access the serial console. He’s done it again with MK908 mini PC featuring Rockchip RK3188. Tx and Rx pads are located on the RAM chips side, and he has connected the green wire to Tx (Going to Rx on TTL debug board), and a yellow wire to Rx (Tx on debug TTL board). A ground pad is available on the other side of the board. Since I got a sample for review from Geekbuying, I decided to give a try myself. The pad are quite small, so this may require patience, but it’s perfectly feasible. I wanted to keep the device closed, so I passed the wires through the ventilation holes (enlarging them a bit with a precision screwdriver), put back the main heatsink on RK3188, and reassembled the enclosure.

Zyxel NSA310 / NSA320 Hackable Network Access Storages Run Debian Linux

Yesterday, we saw how to make a NAS enclosure for the Cubieboard, but DesertF0x commented “Better take a NSA-310 or NSA-320. It is easy to install Debian and it has Gigabit!”, and I decided to have a look. The 2 devices appear to have been released at the end of 2011, and are powered by a Marvell ARMv5 compatible processor. Many NAS are expensive kits, but NSA310 (1 bay) is currently available for $88.50 and NSA320 (2 bays) for $95.34 on Amazon, which is just a little cheaper than the DIY Cubieboard NAS solution (~100 USD). Price looks attractive, now let’s have a look at some technical details, and instructions to install Debian. Both NAS more or less share the same hardware specifications except for a few details: Processor – Marvell Kirkwood 88f6281 ARMV5-TE compliant processor @ 1.2 GHz (Hardware datasheet) System Memory – 256 MB (NAS310) or 512 MB […]

MINIX NEO X7 Quad Core Set-top Box Redesigned, Available Soon

When MINIX unveiled their RK3188 based MINIX NEO X7 at the Hong Kong Electronics Fair in April, they showcased a new enclosure design. Many people seemed to dislike the new “Lamborghini” casing, but the company listened to complains, and redesigned it to a more traditional casing, very similar to the one used for NEO X5. The company also disclosed the official specifications. SoC- Quad core Cortex A9 processor with quad core Mali-400 GPU (Rockchip RK3188) System Memory – 2GB DDR3 Storage – 16GB NAND Flash + SD/MMC card reader (SD 3.0, MMC V4.41) Connectivity: 802.11 b/g/n Dual-band Wi-Fi (2.4 / 5GHz) with external antenna 3G support via external USB dongle (not provided) 10/100M Ethernet (Supports hotspot sharing via Wi-Fi) Bluetooth V4.0 Video Output – HDMI 1.4a, full HD 1080p, 3D movie file format supported Audio Output/Input – HDMI 1.4a two channels, optical S/PDIF AC3 multi-channel, headphone and microphone jacks USB – […]

Cloud Media FreeOTT Player Review

Syabas was a company designing set-top boxes such as Popcorn Hour Media Tank that were relatively popular before the Android media player invasion. The company is now called Cloud Media, and they offer a tiny media player called FreeOTT that connects to their Apps Market and bring online video, Internet radio, social media and other streaming media to your television. The device is free (as in free beer), as it’s not actually available for sale to the general public, and the only ways to get it is to have your ISP or telecom provider set it to you, or win one from the regular giveaways organized by the company. I won one via a giveaway announced on their Facebook page, and I had just to pay $5 (via Paypal) for shipping. The company does not provide detailed specifications for their device but we do know it’s a Linux based media […]
