$80 MK818 / MK818B Android Set-top Box Sits on Top of Your TV

There are already a few set-top boxes that are designed to be placed on top of a television such as Archos Connect TV. Those usually come with a webcam, which makes them ideal for video conference, and much more convenient than mini PCs with a webcam such as Measy U2C or B12. GeekBuying is now offering such device with the MK818B (aka MK818) powered by RockChip RK3066 with 1 GB RAM, 8 GB Flash, and a 0.3 MP front camera for $84.99. They could probably have done without the “so far away, yet this close!” marking at the front of the device… MK818B has the following specifications: SoC – Rockchip RK3066 Dual Core Cortex A9 @ 1.6 GHz + Mali-400MP4 GPU System Memory – 1GB DDR3 Storage – 8GB NAND Flash + SD Card slot (Up to 32GB) + micro SD Card slot (Up to 32GB) Camera – Built-in front […]

How to Autostart XBMC in Android

Android is great thanks to its versatility and the ability to install the apps you need. However, if you have an Android set-top box or mini PC connected to your TV, you may just want to use it as a media player running XBMC, and clicking on the XBMC icon each time you start your device is not ideal. Luckily, there’s an easy solution to autostart XBMC or any application in Android: Install AutoStart – No root in your Android device. Run the application and select XBMC as shown below. There’s no need to tick “Show notification at boot-up”, since XBMC will just show in the foreground. Done! Next time you restart your device XBMC will run automatically. I’ve tried it in Tronsmart Prometheus, and it boots to XBMC within 50 seconds. If you want to use another app in Android, simply exit XBMC.

Updated Review of Tronsmart Prometheus with Android 4.2 and XBMC

Earlier this month, a new firmware for Tronsmart Prometheus with Android 4.2 and XBMC with hardware acceleration has been released. Several users left divergent opinions about this firmware, so I’ve decided to give it a try, and write an updated review of Tronsmart Prometheus. I’ll focus on the new features and performance of Android 4.2, XBMC video testing, and see if some of the bugs I found in my earlier review have been fixed. Android 4.2 Features and Benchmarks The firmware file and instructions are available on Tronsmart website. The procedure is straight forward so I won’t repeat it here. During the first boot after the upgrade, you’ll be taken through a wizard to configure your device (e.g. Ethernet, WiFi,…). The first think you’ll notice is a slightly different Home Screen in Android 4.2. There are several small UI improvements / modifications, but the most interesting features for me in […]

Linaro 13.03 Release with Linux Kernel 3.9 and Android 4.2.2

Linaro 13.03 is now available, and features Linux Kernel 3.9-rc3 and Android 4.2.2. This month, Linaro has released their first Origen Quad Android image, as well as Tiny Android build for Arndale. The ALIP image listed in the download page is still based on Ubuntu 12.11, but as doc Bormental noticed earlier this month, the latest ALIP Quantal 13.03 image is available for download at https://releases.linaro.org/latest/ubuntu/quantal-images/alip. Some development tools (gcc, g++, vi, make..) are now included in Android, so you can develop and build natively from your Android device. Linaro has kept on cleaning the Linux kernel ARM tree for Exynos and ST Ericson SoCs. More work has been done on big.LITTLE for both IKS and HMP, as well as ARMv8 OpenEmbedded, and an initial GRUB port on ARM UEFI is now available. Here are the highlights of this release: Automation and Validation A simple CLI tool for communicating with […]

Droid Stick A2 mini PC Recovery with AMLogic’s Hardware Flash Tool

In some circumstances, for example by installing the wrong firmware or doing something wrong by playing god (as a root user), it’s possible to brick your device. This happened to me with one of my Droid Stick A2 mini PCs based on AMLogic AML8726-MX. I changed some files in /system/etc/permissions directory, lost Wi-Fi access, and even replacing my changes with the backup files would not solve the problem. It also changed some permissions in the system, and it was not possible to restore the firmware the usual way. At the end of last month, dbtablets left a comment with download links to “Amlogic USB Burning tool”, but I only decided to give it a try today, and after some efforts I was successful. Just make sure you only use this method as last resort, i.e. a standard firmware upgrade does not work, and you’re about to throw your device in […]

UG008 and UG008B Rockchip RK3066 Android 4.1 Set-Top Boxes

For those of you who prefer to have a full sized set-top box with an Ethernet port powered by Rockchip RK3066, there aren’t that many options (i.e. Mini X5, TVi7, Wise TiVi Box) and they are usually significantly more expensive than equivalent mini PCs. But there’s no a cheaper option with UG008, a media player powered by Rockchip RK3066 with 1GB RAM, 4 to 8 GB Flash, as well as Ethernet and Wi-Fi support, that sells for around $62 and up. Here are the specifications of this media player: SoC – RK3066 Dual Core Cortex A9 @ 1.6 GHz + Mali-400 MP4 GPU System Memory – 1GB DDR3 Storage – 4 to 8 GB NAND Flash + micro SD slot (up to 32GB) Connectivity Wifi – 802.11b/g/n with external antenna 10/100M Ethernet Video Output – HDMI + AV Video Formats and Codecs – WMV, ASF, MP4, 3GP, 3G2, M4V, AVI, […]

Mini PCs (MK802+, UG802, GK802 & iStick A200) Linux Performance Comparison

Ian MORRISON (linuxium) has tested Linux with several mini PCs powered by different processors. The main point of his tests was to evaluate the performance difference between running Ubuntu 12.04 natively, or in a chroot in Android using tools such as Complete Linux Installer. I previously tried Linux on Android in ODROID-X, and found the applications start time when running from an low-end SD card pretty dismal, and the graphics performance poor. Ian had a different approach, and decided to use a subset of Phoronix Suite benchmarks to compare different hardware / software combination and posted the results in “mini PCs” G+ community. There’s a lot of data, and analyzing the results is not really straightforward without spending some time looking at the data. In this post, I’ll explain how the tests have been conducted, explain the results and try to draw a conclusion. Mini PCs and other Hardware Under […]
