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 […]

BeagleBone Enhanced Adds Gigabit Ethernet, More Memory & USB Ports, and Sensors (Crowdfunding)

It’s nice to see BeagleBone Black‘s open source hardware  being leveraged by third parties, as we’ve already seen designs such as BeagleBone Green and BeagleBone Black Industrial 4G in the past, and now UK based SanCloud has decided to launch BeagleBone Enhanced on Indiegogo (flexible funding). BeagleBone Enhanced board specifications with bold highlights showing improvements over the BeagleBone Black Rev.

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 […]

WeTek Hub Android & OpenELEC TV Box Features Amlogic S905-H Revision C Processor

WeTek has been working not on one, but two four new devices recently. I’ve already covered WeTek Play 2S (previously known as WeTek Play+) based on Amlogic S905 Rev. C , running Android 5.1 or OpenELEC, and featuring digital TV tuners (ATSC, DVB-S2, DVB-T2/C), which should become available in Q2 2016. The company has unveiled another model called WeTek Hub with features closer to the ones found in other Amlogic S905 TV boxes I’ve reviewed so far, except it is based on Amlogic S905-H revision C,  comes with Widewine and Microsoft PlayReady DRM, and supports both Android 5.1.1 and OpenELEC. WeTek Hub specifications: SoC –  Amlogic S905-H revision C quad core ARM Cortex-A53 @ up to 2.0GHz with penta-core Mali-450MP GPU @ 750 MHz System Memory – 1 GB DDR3 Storage – 8 GB eMMC flash + micro SD card slot Video & Audio Output – HDMI 2.0 up to […]

How to Resize Partitions and Update Firmware in MXQ-4K TV Box (Rockchip RK3229)

Since I’ve received MXQ-4K Android TV box yesterday, I have started to play with it, and so far I can’t say I’m impressed, as while the device automatically detected the maximum resolution (3840×2160 @ 60 Hz) for my television, I could not play any of my 4K samples smoothly with either the pre-installed Kodi 15.2, Video and Video Player apps, there’s no power off mode (only standby), and the “internal partition” is only 0.96GB large which can quickly become an issue if you plan on installing several apps. Since GeekBuying has released the stock firmware, I decided to try to adapt the method to resize the partitions for GeekBox (RK3368) to MXQ-4K. Rockchip RK3229 Firmware Modding I’ve used a computer running Ubuntu 14.04, and assume you have most tools pre-installed. The first step is to download the firmware (MXQ-4K_ota_ok_20160127.img update.img), and install the tools to extract it :

$61 Xiaomi Mi Box 3 2016 Enhanced Edition is Powered by Mediatek MT8693 Hexa-core Cortex A72 + A53 Processor

There are few ARM Cortex-A72 “class” mini PCs available on the market, and the only one I can think of is Amazon Fire TV 2015, powered by Mediatek MT8173 hexa-core processor, and priced decently at $99.99, but hard or expensive to source if you don’t live in the US. There will soon be one more choice, as Xiaomi has upgraded its Mi Box 3 to use Mediatek MT8693 processor with two Cortex-A72 cores, and four Cortex-A53 cores combined with PowerVR GX6250 GPU. Xiaomi Mi Box 3 Enhanced / 2016 Edition specifications: SoC – Mediatek MT8693 hexa-core processor with two Cortex-A72 cores @ 2.0GHz, four Cortex-A53 cores @ 1.6 GHz, and Imagination PowerVR GX6250 GPU System Memory –  2GB 64-bit LPDDR3 memory Storage – 8GB eMMC 5.0 flash Video Output – HDMI 2.0 up to 4K/2160p @ 60 Hz Video and Audio Features – 10-bit H.265, Dolby and DTS audio Connectivity […]

Firefly-RK3288 Reload Board Features a SoM + Baseboard Design, Supports SATA, Three HDMI Ports, and More

Firefly-RK3288 was one the first boards powered by Rockchip RK3288 quad core Cortex A17 processor, and now Firefly team, part of T-Chip technology, has provided a new version called Firefly-RK3288 Reload with the same processor, but more features, and thanks to design comprised of a carrier board and system-on-module (SoM) – connected via an MXM connector – suitable to people or companies wanting to create their own board without handing the complexity of the processor, memory, and storage part. The table below shows Firefly-RK3288 and Firefly RK3288 Reload specifications side-by side.

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, […]
