Stream Live TV to Your Computer or Smartphone with U4 Quad Hybrid Android TV Box, Kodi and TVheadend

TVheadend is a streaming server and recorder for Linux, FreeBSD and Android supporting DVB-S, DVB-S2, DVB-C, DVB-T, ATSC, ISDB-T, IPTV, SAT>IP and HDHomeRun as input sources, and while in theory it should be possible to configure any recent Android TV set-top box with digital TV tuners, configuration is complex, and there’s no guarantee the tuner will be recognized. However, the manufacturer of U4 Quad Hybrid has already configured their box to support HTSP clients, so I’ve installed the latest firmware, and given it a try with my Android smartphone running Kodi 15.2 with TVheadend HTSP client, and I could successfully stream live TV (DVB-T2 free-to-air channels) to my smartphone. Once you’ve scanned the channels using DVB-T2 and/or DVB-S2, there’s no other configuration in U4 Quad Hybrid TV box, but you’ll still need to find out your IP address by going to Setup->Network, and WiFi, Ethernet or 3G depending on your […]

RPi-Monitor is a Web-based Remote Monitoring Tool for ARM Development Boards such as Raspberry Pi and Orange Pi

It can be pretty useful to monitor the CPU load, memory and storage usage, and network traffic of your boards, and they are already graphical tools like System Monitor on Ubuntu providing most of the information, and monit can be used on server, but I’ve recently been introduced to RPi-Monitor utility for Raspberry Pi and Orange Pi boards (patched version), that very easy to install, and provide neat chart of many different variables. Since I’m currently playing with Orange Pi One board running armbian, so that’s the platform I’ve used to run RPi-Monitor (OPi-Monitor). The usage should be exactly the same on Raspberry Pi, but the installation steps are little different. To install RPi-Monitor on Orange Pi One, open a terminal or access the serial console, and you can install and start the service with a single command line:

It actually took around 8 minutes on my board, as […]

Accelerated 3D Graphics, Hardware Video Decoding, and Network Performance on Orange Pi One Board (Video)

I’ve just written Getting Started Guide for Orange Pi One, a $10 development board based on Allwinner H3 quad core Cortex A7 processor, where I explain how to install and configure Armbian distribution on the board. As promised, I’ve also tested 3D graphics acceleration, and hardware video decoding, and also included some Ethernet benchmarks. Since ARM Mali-400 GPU found in Allwinner H3 is only capable of OpenGL ES, as in most ARM SoCs, you can test 3D graphics acceleration by using es2gears (and not glxgears as I’ve seen some other do in the past):

The log shows the utility is using Linux-r3p0 Mali driver, and the gears are display at a high frame rate close to 300 fps. If I switch to full screen, the frame rate drops to about 43 fps, which should still be acceptable. CedarX is the infamous closed source and GPL violating media library released […]

Orange Pi One Board Quick Start Guide with Armbian Debian based Linux Distribution

Orange Pi One board is the most cost-effective development board available on the market today, so I decided to purchase one sample on Aliexpress to try out the firmware, which has not always been perfect simply because Shenzhen Xunlong focuses on hardware design and manufacturing, and spends little time on software development to keep costs low, so the latter mostly relies on the community. Recently, armbian has become popular operating systems for Linux ARM platform in recent months, so I’ve decided to write a getting started guide for Orange Pi One using a Debian Desktop image released by armbian community. Orange Pi One Unboxing But let’s start by checking out what I received. The Orange Pi One board is kept in an anti-static bag, and comes with a Regulatory Compliance and Safety Information sheet, but no guide, as instead the company simply asks users to visit www.orangepi.org to access information […]

K3 Wintel Windows 10 Keyboard PC Review

GeekBuying sent me K3 Wintel keyboard computer since I was interesting in testing a device in this form factor, and at the time I listed the specifications, and took a few pictures of the device and its internals. I’ve now completed the review, and found it to perform very well for a Bay Trail computer. K3 Wintel Key Computer Setup & System Info But the initial part of the review did not start so well, as I was asked for a license key for the device as went through the initial setup right after selecting my languages and regional settings. GeekBuying clearly states the mini computer comes with a “Licensed Windows 10”, and I could not find any on the device or the user’s guide, which appears to be a near-exact copy of a Windows 10 Lenovo tablet PC user’s guide… So I contacted GeekBuying, and after a few days, […]

Using a Cheap USB Microscope To Read IC Part Numbers

It’s not always easy to read the part number on IC you find on boards, and some time ago, I watched a video where Lady Ada used a USB microscope to demonstrate how to solder some components, and probably using that 5.0 MP model sold on Adafruit for about $80. But I found a similar looking USB microscope with a 2.0MP sensor and 1000X magnification on Ebay for $16.59 shipped, so I bought it, received it today, and I’ve given it a try. Such microscopes can be used to inspect skin and hair, PCB, textile, bank notes, jewelery, and so on. There are apparently other models based on the one I purchased with useful features like auto-focus, wireless support, different levels of magnification, and different colors. Supported operating systems include Windows and Linux, Android, and Windows 8 according to the package. The microscope comes with a stand, a CDROM with […]

10-bit H.264 and H.265 Video Playback in MXQ-4K Rockchip RK3229 TV Box

Rockchip RK3229 is an exciting media processor because it’s found in ultra low cost TV Boxes such as MXQ-4K, outputs up to 4K @ 60 Hz, and supports 4K video decoding of 10-bit H.264, 10-bit H.265 and VP9, including videos with very high bitrates (200+ Mbps). That’s the theory, which I’ve put to the test with MXQ-4K TV box. Since the network interfaces of the device are limited to 100M Ethernet and 802.11n WiFi, and some videos are well above 100 Mbps, I’ve decided to test video playback from a USB hard drive instead. I’ve tried the three pre-installed video player apps: Kodi 15.1, “Video”, and “Video Player” , and they all have similar capabilities except Kodi is a little less stable on this device. The system detected my 4K TV (LG ) and automatically set the resolution to 3840×2160 @ 60 Hz, which I used for the remainder of […]

MXQ 4K Rockchip RK3229 Android TV Box Unboxing and Teardown

MXQ 4K TV box list of features is rather impressive, as the 4K media player packs support for high bitrate (200 Mbps+) 10-bit H.265 and H.264, as well as VP9 at 4K resolution, 4 USB ports, Ethernet, and HDMI 2.0 for just $30. That price includes shipping. We just don’t know how it performs, but we’ll soon find out as GeekBuying sent me a sample for review. I’ll start by checking out the hardware, before testing it over a few days, and write a complete review. MXQ 4K Unboxing The retail package shows MXQ-4K  “OTT TV Box” and some of the key selling points like Kodi support, 4K, HEVC/H.265, and son on. You’ll also find the Android 4.4 Kitkat logo since strangely Rockchip did not provide an Android 5.x SDK for their low cost processor. The device ships with an IR remote control, a 5V/2A power supply, an HDMI cable, […]
