How to Reduce SD Card Firmware Images Download Size

So I’ve just received a Roseapple Pi board, and I finally managed to download Debian and Android images from Roseapple pi download page. It took me nearly 24 hours to be successful, as the Debian 8.1 image is nearly 2GB large and neither download links from Google Drive nor Baidu were reliable, so I had to try a few times, and after several failed attempt it work (morning is usually better). One way is to use better servers like Mega, at least in my experience, but another way to reduce download time and possibly bandwidth costs is to provide a smaller image, in this case not a minimal image, but an image with the same exact files and functionalities, but optimized for compression. I followed three main steps to reduce the firmware size from 2GB to 1.5GB in a computer running Ubuntu 14.04, but other Linux operating systems should also […]

LeMedia is a Linux Distribution based on Debian and Kodi 15.2 for Actions Semi S500 Processor

LeMaker has recently released LeMedia, a Linux distribution based on Kodi 15.2 and Debian Jessie for their Guitar board powered by Actions Semi S500 quad core Cortex A9 processor, also found in Lemon Pi, ActDuino-S500 and Roseapple Pi boards. The good news is that H.264 and MPEG4 hardware video decoding is implemented, as well as PowerVR SGX544 GPU 3D acceleration. This is an early version and while IR receiver, WiFi, HDMI and LCD output, and audio are working, the company explained that HDMI support may be flaky, USB 3.0 speed is not optimal, and touchscreen support had to be disabled. They also included a “LeMedia Settings” in the image to have a similar experience as “RaspBMC Settings”. The images for booting from SD card or eMMC can be downloaded here. It’s quite likely they only work on LeMaker Guitar board, and I could not find the Linux 3.10.37 kernel, nor […]

WeTek Core 4K Media Player Unboxing and Teardown

WeTek Core is the latest media player from WeTek Electronics, based on Amlogic S812-H processor with 2GB RAM, and 8GB flash. By default, it will ship with Android 5.1 using DRM libraries enabling Netflix HD, but you’ll also be able to install OpenELEC, and later on Lubuntu once/if the community gets involved like for WeTek Play. The company sent me one sample, and I’ll start by checking out the device and internal hardware. WeTek Core Unboxing That’s the package which lists the specifications and provides links to WeTek Facebook page and forums. The box ships with a 12V/1A power adapter with clippable US, EU and UK plugs, an HDMI cable, WeTek’s IR and RF 6-axis remote control with voice search function, a small (and cool) tool for firmware updates, and a blue document showing the device’s ports. The power button and LED are located on one of the corners at […]

Weightless Development Kits are Finally Available (Sort of)

The first version of the Weightless standard aiming at lowering cost of IoT communications was published in 2013, but so far development kits were nowhere to be found. Nwave has now launched a Weightless-N SDK using sub-GHz spectrum, but not the white space spectrum used by Weightless-W, probably due to regulatory hurdles. Specifications and features of Nwave development board: MCU – Silicon Labs EFM32G210F128 ARM Cortex M3 MCU @ 32 MHz with 128KB flash, 16KB SRAM Connectivity – RM3 radio module (868MHz) and antenna connector (X3) USB – X1 USB port for connection to PC or UART interface, X2 micro USB port Debugging – UART, and 10-pin JTAG connector (X4) Expansion header – 16 through holes for GND, 3.3V, GPIOs, ADC, Timers output, I2C, etc… (X5) Misc – Three Jumpers for UART and other selections (TBD), reset buttons for USB ports? Power – 5V via USB ? Dimensions – N/A […]

Zidoo X6 Pro Android TV Box Review

Zidoo X6 Pro is a 64-bit ARM Android TV Boxes  based on Rockchip RK3368 processor, promising support for HDMI 2.0 and video decoding up to 4K2K @ 60Hz. While the others I’ve tried so far, such as Beelink i68,  are pre-loaded with some version of Kodi 14.2, X6 Pro comes with a modified version of Kodi 15.1. I published pictures of the Zidoo X6 Pro TV box and board a few days ago, and today I’ll review the box’ features, performance, and capabilities. First Boot, Settings and First Impressions I’ve connected a USB hard drive to one of the two USB ports, as well as a USB hub with two RF dongles for Tronsmart Mars G01 gamepad and MeLE F10 Deluxe air mouse, a USB keyboard, and a USB webcam. I’ve also inserted an Ethernet cable, an HDMI cable, an optical audio cable, a Class 10 micro SD card, as […]

Xiaomi Mi Smart Remote Center Review

Xiaomi Mi Smart Remote Center is a tiny box with WiFi connectivity and IR transmitters that is used to control infrared enabled devices such as TVs, medai players, air conditioners and more with your Android smartphone. The good thing is that it only costs $20, so I asked GearBest to send a sample to check it out, which they did. I’ll start this review by checking out the hardware, before running MiHome app to control a television and air conditioner. Xiaomi Mi Smart Remote Center Unboxing and Teardown The package is just a cardboard box with Mi logo. Once you open the page there’s a sticker with the QR core redirecting to MiHome app. You can peel it off, and take the box out of the package, where you’ll also find a USB to micro USB cable for power, and a user’s manual in Chinese only.

AMS AS7000 Biosensor is Designed for Strapless Optical Heart Rate Monitors

Heart rate monitors (HRM) with chest straps are now being replaced by more comfortable strapless HRM, such as UWatch UX. These products are enabled by photoelectric sensors that sample light modulated by blood vessels, which expand and contract as blood pulses through them. One of such solutions is the recently introduced AMS AS7000 including a Cortex M0 core, and a DSP implementing algorithm to process raw photoplethysmography (PPG) readings from the sensors to convert them into digital HRM and HRV (Heart Rate Variability) values. Highlights of AS7000 Biosensor: MCU – ARM Cortex M0 with 4KB RAM, 32 KB EEPROM I/Os – 9 GPIOs, UART, SPI, I2C Analog electrical and optical Frontends Hardware sequencer Synchronous detector Integrated LEd driver with current control Optical filters Supply Voltage – 2.6 – 3.6V Temperature Range –30 to 70°C Package – 18 pins AS7000 can deliver greater accuracy when it is paired with an external […]
