NO.1 D3 Smartwatch Specs, Unboxing and Teardown

There are now many wearables, including fitness bands and smartwatches, on the market, but to me many fail on battery life, visibility, and price. The one that would match my requirements the best would be SMA-Q smartwatch, but in the meantime, I’m also interested in testing some more wearables at different price points. Tinydeal sent me NO.1 D3 smartwatch that sells for just $22.99 shipped. I’ll go first through the specifications, before checking of the watch more closely, and in a few days writing a review of the device. NO.1 D3 Smartwatch Specifications You should not expect much for this price, but the watch is surprisingly feature-packed (as taken from tinydeal website): SoC – Mediatek MT6261 processor with 32Mbit RAM, 32Mbit Flash Storage – Internal micro SD slot up to 16GB Display – 1.22″ capacitive touchscreen IPS display with 128×128 resolution Connectivity – Bluetooth 3.0 Cellular – 1x micro SIM […]

Amlogic S905 vs Rockchip RK3368 Benchmarks Comparison

The first Amlogic S905 TV boxes have started to ship, and I received Videostrong K1 Plus a few days ago, but due to some issues with Google Play Store, I’ve decided to postpone the review. In the meantime, I’ve side-loaded popular benchmark apps including Antutu, Vellamo, and 3Dmarks to the device to compare it to its main 64-bit ARM competitor: Rockchip RK3368. I used benchmark results from Beelink i68 review and compared them to K1 Plus, both devices running Android 5.1. A ratio greater than 1 (green) mean S905 is better, while a ratio lower than 1 (red) means RK3368 fares better. Amlogic S905 Rockchip RK3368 Ratio CPU Quad core Cortex A53 @ 2.02 GHz* Octa core Cortex A53 @ 1.2GHz GPU ARM Mali-450MP PowerVR G6110 Antutu 5.x Overall 28,027 34,171 0.82 Multitask 4,260 4,041 1.05 Runtime 2,721 2,949 0.92 RAM Ops 1,960 2,346 0.84 RAM Speed 2,420 2,601 0.93 […]

Amlogic S905 Source Code Published – Linux, U-Boot, Mali-450 GPU and Other Drivers

Amlogic has an open linux website where they regurlarly release GPL source code, and with Amlogic S905 devices coming to market, they’ve released a few tarballs at the beginning of the month including Linux 3.14 source code, U-boot source code, and Mali-450MP GPU kernel source code (obviously not userspace), as well as some other drivers for WiFi, NAND flash, PMU, TVIN, etc… Let’s get to the download links: Linux 3.14.29 source code U-boot 2015.01 GPU drivers for ARM Mali-450MP Broadcom and Realtek Wifi drivers and firmware (November 4, 2015) can be found @ http://openlinux.amlogic.com:8000/download/ARM/wifi/. Other kernel modules (November 4, 2015) @ http://openlinux.amlogic.com:8000/download/ARM/modules/. I quickly tried to build the Linux source. If you’ve never build a 64-bit ARM kernel or app before, you’ll fist need to install the toolchain. I installed the one provided with Ubuntu 14.04:

sudo apt-get install gcc-aarch64-linux-gnu

1	sudo apt-get install gcc-aarch64-linux-gnu

Now extract the tarball and enter the source directory:

tar xvf arm-src-kernel-2015-11-04-9e845bea41.tar.gz 
cd arm-src-kernel-2015-11-04-9e845bea41

RedBear Duo is a Breadboard-friendly Wi-Fi + BLE IoT Board Based on Ampak AP6212 Module (Crowdfunding)

I’ve taken apart lots of TV boxes and together with Realtek, Ampak are by far the most popular wireless modules to provide WiFi and Bluetooth connectivity in those devices. One startup decided to use Ampak AP6212 module, also found in NanoPi 2 board, to create a breadboard-friendly IoT board with Bluetooth 4.0 and 802.11b/g/n connectivity. Redboard Duo has been designed with the same form factor as many other IoT boards such as NodeMCU or Spark Photon, and features the following: Ampak AP6212 module: STMicroelectronics STM32F205 ARM Cortex-M3 @120MHz, 128 KB SRAM and 1MB Flash Broadcom BCM43438 Wi-Fi 802.11n (2.4GHz only) + Bluetooth 4.1 (Dual Mode) combo chip Storage – On-board 16 Mbit (2 MB) SPI Flash Integrated chip antenna with the option to connect external antenna Expansion – Headers with 18 I/O pins Misc – RGB status LED Dimensions – 20.5mm x 39mm The company also made a small baseboard called RBLink with […]

MX HD23 Allwinner H3 Android Mini PC Includes an HD Camera

When Android TV boxes started to take off around 2013, a few model would include a camera and sit on top of the TV such as MK818. However I’ve seen less model in that form factor since then, until I came across MX HD23 Android TV Box powered by Allwinner H3 quad core processor and featuring a HD webcam for videoconferencing. Beside the camera, MX HD23 specifications are pretty standard: SoC – Allwinner H3 quad core ARM Cortex A7 @ 1.2 GHz with quad core Mali-400MP2 @ 600 MHz System Memory – 1 GB DDR3 Storage – 8 GB eMMC + micro SD slot up to 32GB Connectivity – 802.11 b/g/n Wi-Fi Video Output – HDMI up to 4K2K @ 30Hz, 3.5mm AV jack Audio Output – HDMI, and 3.5mm stereo audio jack Camera – 2.0 MP front-facing camera with two microphones (up to 5 meter range) and swivel arm.
