Linux 3.18 Released

Linus Torvalds released Linux Kernel 3.18 last Sunday: It’s been a quiet week, and the patch from rc7 is tiny, so 3.18 is out. I’d love to say that we’ve figured out the problem that plagues 3.17 for a couple of people, but we haven’t. At the same time, there’s absolutely no point in having everybody else twiddling their thumbs when a couple of people are actively trying to bisect an older issue, so holding up the release just didn’t make sense. Especially since that would just have then held things up entirely over the holiday break. So the merge window for 3.19 is open, and DaveJ will hopefully get his bisection done (or at least narrow things down sufficiently that we have that “Ahaa” moment) over the next week. But in solidarity with Dave (and to make my life easier too 😉 let’s try to avoid introducing any _new_ […]

Hardkernel ODROID-C1 is a $35 Development Board Powered by Amlogic S805 Quad Core Processor

Amlogic S805 is a quad core Cortex A5 processor which has found it way into low cost devices such as MK808B Plus TV Stick which can be purchased for as low as $30, or full-sized TV box such as MXQ S85 or MINIX NEO X6. All this low cost devices are nice, but the full source code is not available in your want to adapt them to your need. Luckily, Amlogic releases both an Android SDK, and a buildroot for Linux with GPU and Video Processing Unit (VPU) support, so Hardkernel decided to go ahead, designed a board, and has just launched ODROID-C1 quad core development board for just $35, or the exact price of a Raspberry Pi Model B+, but with much greater specs. ODROID-C1 specifications: SoC- Amlogic S805 quad core Cortex-A5 processor with a Mali-450MP2 GPU (2x fragment cores + 2x vertex shader cores) System Memory – 1GB […]

How To Upgrade Firmware on Ugoos UM3 mini PC

Ugoos released two new dual boot Android / Ubuntu images for Ugoos UT3 and UM3, which reduces the size of the system by 300MB, includes LibreOffice, replaces Firefox by Chromium + PepperFlash plugin, and fixes various bugs: ut3_dualboot_v0.2.rar – For UT3 full sized TV box UM3_dualboot_v0.2.rar – For UM3 mini TV box The firmware update procedure for Rockchip RK3288 is well-known, and Ugoos even includes a word file with flashing instructions in Microsoft Windows with the firmware images. However, it still took me about one hour to find out how to do with Ugoos UM3, so I thought I’d write a post in case others encounter the same issue. I flash the firmware in Ubuntu, so instead of using Android Tool, I flashed it with upgrade_tool command line utility I got from Orion R28 SDK, but you can also download Linux_Upgrade_Tool_v1.2.tar.gz directly. First let’s enter recovery mode. The procedure is […]

Kairos T-Band is a Smart Watchband for Your “Dumb” Watch (Crowdfunding)

Kairos introduced a high-end mechanical smartwatch with a semi-transparent OLED display a few months ago. They’ve now launched an Indiegogo campaign to sell several models for $500 to $1,000+, but they’ve also introduced T-Band, a smart watchband with an integrated display that you can fit to your existing (mechanical) watch, in order to receive notifications, answer phone calls, get directions, and even start your car. There are three models of smartband all running Kairos OS on an ARM Cortex M4 MCU @ 168 MHz with Bluetooth Classic / Low Energy: T-Band ND (No Display) Alerts user of notifications via a vibrator and LED indicator, and tracks fitness / sleep, as well as health data. Sensors – 9-axis gyroscope, accelerometer, compass, optical sensor, and GSR (Galvanic Skin Sensor) which detects skin temperature and sweat. Audio – Digital MEMS MIC for text to speech capabilities (requires 3rd party app) Battery – 200 mAh […]

Polaroid Socialmatic Android Camera Prints Photos on The Go

Polaroid used to make instant cameras allowing you could take a picture, and print it immediately. As digital photography became more and more popular, this type of cameras mostly disappeared, but Polaroid is giving it another go with Socialmatic camera running Android, that can print regular pictures and even selfies thanks to its rear and frontal cameras, using its embedded ZINK Zero Ink printer. Polaroid Socialmatic specifications: SoC – Unnamed ARM processor System Memory – N/A Storage – 4GB Internal Storage + micro SD card slot Cameras – 14MP frontal camera with LED flash, 2MP rear camera Display – 4.5″ Touchscreen LCD with Mood Assistant A.I.

Battery – Rechargeable lithium-ion battery Dimensions – 13.2 cm x 13.2 cm x 3.0 cm Since the […]

Arduino UNO R3 Clones Now Cost Less than $5

An original Arduino UNO R3 costs about nearly $25, and I remember clones would cost about $10 on Aliexpress, but today I’ve been informed about VISduino, an Arduino UNO R3 clone, with some cost optimizations such as cheaper components and connectors, which sells for just 15.50 CNY (~$2.50 US) on Taobao, and $4.90 on Electrodragon. But double checking on Aliexpress, I could find another popular Arduino UNO R3 clone for $4.58 including shipping, but no USB cable. Both boards cut costs by replacing ATmega16U2 by CH340 USB to serial chip, and replacing the ATMEGA328P-PU MCU (DIP) by an SMT version of the Atmel MCU such as ATMEGA328P-AU (QFP). Other changes on VISduino include: Replaced USB B-type connector by a micro USB port Added extra through holes side-by-side with the Arduino headers for easier debugging. Extra 2×4 pin holes with TX, RX, VCC, GND, and I2C pins You may have to install […]

Hisilicon Hi3798M Quad Core Android TV Box with USB 3.0, and 4K / HEVC Support Sells for $53

I’ve been informed about a quad core Cortex A7 TV box supporting 2160p output, H.265 codec and featuring a USB 3.0 port, that’s currently selling for just $52.99 on Aliexpress including shipping, as well as Ebay for $62 from the same seller. Only “quad core ARM cortex A7” was listed in the specs, and the exact processor was not mentioned, but I could see marketing material about “Q3 quad core” used, and a quick search redirected me to Himedia Q3 Quad Core also powered by an Hisilicon processor, but a different device. So I decided to contact the seller (“Buyforsure”) who quickly replied it was indeed powered by Hisilicon Hi3798M processor. The model is called BFS 4KH on Aliexpress/Ebay, but that name has probably been made up by the seller, so it will also be found under other name. Nevertheless here are the specifications of this low cost 4K TV […]
