AllWinner A80 Octa Core big.LITTLE Processor CPU Usage Under Various Loads in Android 4.4 (Video)

November 23rd, 2014 No comments

Allwinner A80 is one of the few octa core processors featuring ARM’s big.LITTLE technology currently available on the market. The processor comes with four ARM Cortex A15 (big) cores, and four ARM Cortex A7 (LITTLE) core, and tasks will be scheduled to different processor depending on the load to optimize power consumption on mobile devices. However, earlier big.LITTLE processors like Samsung Exynos 5410 has some serious limitations, as they only supported “cluster migration” meaning you could only use the Cortex A7 cluster or Cortex A15 cluster at any given time, so Exynos 5410 could only make use of four cores at most due to hardware limitations. They also used to be two software implementations: In-kernel Switching (IKS) and Global Task Scheduling (GTS). The former could only handle one type of core at the same, and the latter, which I believe…

Unboxing of Zero Devices Z5C Thinko TV Stick based on Rockchip RK3288 Processor

November 22nd, 2014 2 comments

It’s been a long long while since I’ve received an Android HDMI TV Stick, probably because many people prefer TV boxes, and the new ARM processors usually dissipate a lot of heat so thermal management may be an issue with small form factors. But I’ll finally get the opportunity to test a powerful HDMI dongle based on Rockchip RK3288 quad core processor, as Zero Devices sent me their Z5C Thinko TV stick. I’ll start by listing the specifications, and taking some pictures of the device and the board, because doing a full review hopefully sometimes next week. Zero Devices Z5C Thinko Specifications The stick has specifications similar to full sized Android media player minus ports like Ethernet and S/PDIF: SoC – Rockchip RK3288 quad core Cortex A12/A17 @ 1.8 GHz + ARM Mali-T764 GPU with support for OpenGL ES 1.1/2.0…

ODROID-XU3 Lite Development Board – Android Setup and Benchmarks

November 21st, 2014 14 comments

It’s been nearly ten days since I make ODROID-XU3 Lite unboxing, and my plans to first test Linux on the board were thwarted due a problem with HDMI. Luckily, after several attempts I managed to boot the board with Android. So today, I’ll show how to install or update Android on the board, and run a few benchmarks. But since there’s always a silver lining, I’ll start buy writing a bit about the HDMI issue, as I learned a few things on the way. HDMI Output Tribulations ODROID-XU3 Lite looks like a nice and powerful kit, and it may be one of the most cost effective ARM board on the market since it comes to performance to price ratio, so I was excited to try it, but as you know if you’ve read my unboxing post I did not work…

$19 Broadlink SP mini Wi-Fi Smart Plug for Android and iOS

November 21st, 2014 6 comments

Many small companies are now making smart sockets including Broadlink, Plugaway, Orvibo, Kankun, and so on. They are various features, some even have energy monitoring support like Broadlink SP2 (But it died after two or three months on mine), and some are more basic like Kankun KK-SP3 as they can only be turn on/off manually or using timers, but at least that one is hackable and runs OpenWRT. Broadlink has now launched a new low cost version in the same price range of KK-SP3 with SP mini Smart Socket selling for as low as $18.69 on Banggood, but it can also be found on other for a little over $20, such as DealExtreme, Ebay, Aliexpress, etc… It sells for 79 RMB ($12.9 US) in China. Broadlink SP mini specifications: Power Plug – Three flat-pin plug (Chinese type) Wi-Fi – 802.11…

Semtech LoRa SX1272 RF Module Enables Up to 30 KM Wireless Range for Arduino, Raspberry Pi, Waspmote, and More

November 20th, 2014 No comments

Libelium’s Waspmote is a board based on Atmel ATmega1281 MCU that interfaces with over 80 sensors, and various wireless communication modules, and targets professional wireless sensor network applications such as irrigation systems, smart metering, smart cities, smartphone detection, building automation, and so on. They have some professional kits for over 3,000 Euros including training, but a more affordable Starter Kit is also available for 199 Euros on Cooking Hacks. But I’m not going to cover Waspmote in details today. I just mention it because of an article on embedded.com mentioning compatibility with a Libelium / Semtech LoRa SX1272 RF module delivering up to 30km range in ideal conditions (and usually 22+ km range in LOS), and about 2km range in urban settings. I previously featured XBee-PRO 900HP RF Module with a 45km range, so the Semtech module is just another option,…
