How to Resize Android’s Internal Storage Partition in Rockchip Devices

I installed Light Biz OS firmware on GeekBox yesterday, but I’ve quickly realized many applications such as Gimp Inkscape would not install due to the small 1.94GB “internal partition”, so I asked how to increase the partition size in GeekBox forums last evening, and got an answer overnight from “dewet”. The good news is that it worked so I’ll share the steps I followed in a computer running Ubuntu 14.04. It might also be possible to perform the same tasks within a Windows machine with Rorkchip’s Factory tools First let’s download the utils with relevant scripts and binaries:

Now copy your device or board’s firmware file “update.img” to the working directory, and unpack it:

The output should look like:

The files will be in the “output” directory. For our purpose “parameter” file, and especially the last line (CMDLINE) where we will want to adjust the userdata partition […]

How to Use Nextion Serial Touchscreen Displays – Part 1: Standalone Mode

Itead Studio launched an Indiegogo campaign earlier this year for their Nextion TFT displays that can be connected to external board such as Arduino or Raspberry Pi via the serial interface, or even a standard computer provided you have a USB to TTL debug board. The campaign was successful with over 1,700 backers, and the company recently sent me two samples for review: a 2.4″ display and a 5″ display. In this post, I’ll look at the boards, and make a small standalone demo with Nextion Editor in Windows. Nextion NX3224T024 2.4″ Display The first item is a 2.4″ TFT display called NX3224T024_011N (non-touch) or NX3224T024_011R (Resistive touch) with 65536 color, 320×240 pixel resolution, LED backlight and up to 200nit brightness. It ships with a cable for the serial connection (5V, Tx, Rx, and GND). The back of the display features the serial connector, a micro SD used to load the […]

Razberry Board and UZB Dongle Add Z-Wave (Plus) to Raspberry Pi Boards

Z-Wave is one of the low power wireless communication protocols used for automation, and supported, for example, by gateways such as Samsung SmartThings Hub or Vera3. Z-Wave Plus is a certification program used to identify Z-wave 5th Generation hardware platform, allowing a greater range up to 45 meters, 50% improvement in battery life, 250% more bandwidth, and providing a standardized method for Over the Air firmware updates (OTA), among other things. Zwave.me, a startup registered in Switzerland, is specializing in Z-Wave products and solutions, and among their other products they’ve also designed Z-Wave hardware to turn the Raspberry Pi board and other compatible hardware into a Z-Wave gateway. RazBerry module will fit into the 26 or 40-pin header found on Raspberry Pi boards, and comes with the following  specifications: Sigma Designs ZM5202 Z-Wave transceiver module Frequencies – Storage – 32KB SPI flash for network data CPU/MCU Interface – UART (Tx/Rx) […]

Samsung Introduces $250 SmartThings Home Monitoring Kit

Samsung has recently launched SmartThings Home Monitoring Kit including a SmartThings hub, a motions sensor, two multi-pupose sensors to detect when windows or doors are opened, and a smart outlet for home automation and monitoring via mobile devices. Some of SmartThings Hub technical specifications: Ethernet for connection to router Communication Protocol – ZigBee, Z-Wave, IP Range – 15 to 40 meters Power Supply – In-wall power adapter with about 10 hours of backup power from 4 included AA batteries Dimensions – 10.67 x 12.45 x 3.3 cm Weight – 218 grams Operating Temperature: 5 to 35°C (Indoor use only) They’ve decided not to include WiFi, or omitted in the product page, so it would have to be close to your router. The multi-purpose sensors, and motion sensor are powered by a pre-installed CR-2450 battery, while the smart outlet takes 100 to 220V (12A @ 120V max). All three devices communicate […]

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 […]

MeLE F10 BT is a $20 Bluetooth Air Mouse and Keyboard

MeLE is mostly known as a manufacturer of Android TV boxes and air mice, and I use MeLE F10 Deluxe air mouse in all my Android mini PCs review, as even though it’s not perfect it does the job much better than an IR remote control, and is more convenient to use than a USB keyboard. The two MeLE air mouse I’ve purchased come with a 2.4GHz RF dongle that needs to be connected to a USB port of the device you want to control,  but now the company is now about to launch a Bluetooth model with MeLE F10 BT. MeLE F10 BT (RF01BL) specifications: Connectivity – Bluetooth 4.0 (CSR1011) IR support – Yes, including IR learning function. Buttons Life – About 100,000 presses Sensors – G-sensor, Gyroscope Keyboard – QWERTY keyboard Battery – 2x AAA batteries (>30 days in standby mode) Dimensions – 169x48x19 mm Beside Bluetooth connectivity, […]

MOI Pro AMD IPTV Streaming Server Supports Up to 16 Tuners

TBS Technologies is a company specializing in digital TV tuners, with their catalog includes various DVB-T2, DVB-C, DVB-S2 and ATSC tuner cards. They also happen to be the designer of Matrix board and Matrix 2 Android set-top box, both of which run Android or Linux and support some of the company’s tuners. But they also have higher end products such as MOI Pro AMD IPTV streamer based on an AMD Embedded G-Series processor, and supporting up to 4 tuner cards with up to 4 tuners each. TBS MOI Pro AMD specifications: SoC – AMD GX-412HC quad core processor @ 1.2GHz with AMD Radeon HD GPU @ 300MHz (7W TDP) System Memory – 4GB DDR3-1333 Storage – 30GB mSATA SSD, 1x SATA @ 6.0Gb/s, Video Output – 1x HDMI, 1x VGA (reserved connection?)

Rockchip’s Light Work OS Makes Android Look Like Windows

Android is not exactly great to use as a desktop PC, so there’s been various attempts to improve this for Android boxes, tablets, and laptops for example with Remix OS, bringing a more desktop-like user experience. Rockchip showcased multi-window supports in some tablets a while ago, and now they have “Light Work OS”,  an operating system based on Android 5.1 that feature a start menu and multiple windows support. PiPo even decided to use a background image with Windows logo in their PiPo X9 tablet powered by Rockchip RK3288. The problem with Android used as a mini PC goes much further than the lack start menu or window mode, but copy/paste can be a pain, and things you take for granted on desktop, simply may not be available in Android apps: some graphics elements may not be clickable, some website features may not work properly (I’m thinking WordPress editing here..), […]
