$25 GL.iNet 6416A is an Hackable OpenWRT Router with Easy UART and GPIO Access

There are plenty of low cost routers supporting OpenWRT, but GL.iNet 6416A has several advantages compared to devices like TP-Link WR703N. Both are based on Atheros AR9931, but GL.iNet router has more memory and storage (64MB RAM + 16MB Flash vs 32MB RAM + 4MB Flash), two Ethernet ports instead of just one, and 6 GPIOs, the serial pins, and power signals (5V, 3.3V and GND) are all easily accessible via though holes or headers. Gl.iNet 6416A can be purchased for about $25 on DealExtreme or Amazon US, and it used to be listed on eBay, but is now out of stock. Gl/iNET 6416A specifications: Wi-Fi SoC – Atheros AR9331 MIPS processor @ 400 MHz System Memory – 64MB RAM Storage – 16MB Flash Connectivity – 2x 10/100 Mbit Ethernet ports, 802.11 b/g/n Wi-FI up to 150Mbps USB – 1x USB 2.0 port, 1x micro USB port for power Debugging […]

Linux (Enlightenment and Lubuntu) in WeTek Play Amlogic TV Box

Last week I reviewed WeTek Play, a TV box with two DVB-S2 tuners, powered by Amlogic AML8726-MX dual core ARM Cortex A9 processor, and running Android 4.2, but the company also released several Linux based images including one with Enlightenment window manager, and another, temporary one, with Ubuntu core which allows you to install Lubuntu or Xubuntu with apt-get. There are also working on OpenELEC, but have not released the binary yet. Today, I’ll try the Enlightenment image because it also supports hardware video decoding via Gplay (gstreamer), and show how to install Lubuntu. The instructions below have been done in a computer running Ubuntu 14.04, but a Windows computer can also be used. Download Wetek-Linux.img.bz2 Connect a micro SD card to your computer, extract and flash Wetek-Linux.img: In Linux using a terminal window:

In Windows, extract the image, and use Win32DiskImager to copy the image to your micro SD […]

How to Build and Run Android L 64-bit ARM in QEMU

[Nov, 2014 Update: The method below does not seem to work anymore, but a 64-bit ARM emulator “emulator64-arm64” has now landed in AOSP, and updated instructions are available here]. Most people can’t afford Juno Cortex A57/A53 development board, and mobile processors based on the latest 64-bit ARM cores are only expected by early 2015. But thanks to a small team at Linaro, you can now build and run Android L 64-bit ARM in the latest version of QEMU that supports Aarch64. Alex Bennée, an engineer working for Linaro, wrote a blog post in Linaro’s Core Dump blog explaining the Android emulator is actually based on QEMU,  the differences compared to mainline QEMU, the work they’ve done on Android L at Linaro, and most importantly, provided the basic steps showing how to build and try Android L 64-bit ARM (ARMv8) in QEMU. I’ve just done that, but unfortunately, albeit the builds […]

Using an Android Mini PC as a Desktop PC (Blogging Version)

I use an x86 computer running Ubuntu 14.04 as desktop PC, spending most of my time working on this blog, which mostly involves reading and writing articles in web browsers (Firefox, Chrome), handling emails, communicating via Social networks, manipulating and editing pictures. But for reviews, I also need to take pictures and videos, tranfer these to my PC, and upload videos to YouTube. When I create tables, I normally type them in LibreOffice Calc, and copy/paste the results in WordPress editor. But this post side, I’ve put my noisy PC aside, and I’m writing from an Android 4.4 TV box, namely Probox2 EX, in order to evaluate how convenient, or not, Android may be for simple computing needs. First let’s indentify some applications used in desktop operating systems such as Windows and Linux (Ubuntu 14.04), and their equivalent in Android. I made the comparison table below in AndrOpen Office (AOO), […]

WRTNode is a Hacker-Friendly Open Source Hardware OpenWRT Wi-Fi Module Selling for $25

There are now some tiny and low cost ($15 to $20) Wi-Fi modules supporting OpenWRT such as VoCore and AsiaRF AWM002. However due to their small size they may not be that hacker’s friendly as they can’t have 2.54mm headers due to heir small size, and I’ve recently received AsiaRF AWM002 only to find out it not only needs 3.3V supply voltage, but also 1.8V and 1.2V. So I’d need to make my own power circuit with the required LDOs, or purchase a $20 base board to use the module. Here comes WRTnode another larger Wi-Fi module but with more usable 2.54mm headers, and based on the more powerful Mediatek MT7620N processor @ 600MHz. WRTnode hardware specifications: Processor – Mediatek  MT7620N 600MHz MIPS CPU (MIPS24KEc) System Memory – 64MB DDR2 Storage – 16MB SPI flash Connectivity – Wi-Fi 2T2R 802.11n 2.4 GHz up to 300Mbps Expansion Headers – 2x with […]
