U5 PVR Deluxe Android Set-Top Box Review – Part 1: Specs, Unboxing, Teardown, and SATA HDD Assembly

Last year, I reviewed U4 Quad Hybrid, an Android TV box powered by Hisilicon Hi3796M quad core Cortex A7 processor and with a combo DVB-T2/C + DVB-S2 tuner. with digital TV tuner. It worked pretty well, except for a few bugs here and there, the processor is not the most powerful, and video output & decoding is limited to 4K  @ 30Hz. The company – Shenzhen Vivant Technology – is now back with a new model called U5 PVR powered by a more powerful Hisilicon Hi3798C V200 quad core Cortex A53 processor with fast interfaces like USB 3.0, SATA, and Gigabit Ethernet, as well as support for 4K @ 60Hz via a HDMI 2.0a interface. There are actually three variations of U5 PVR with Deluxe/Slim/Normal models, and the company sent me U5 PVR Deluxe model for review. As usual, after listing the specifications, I’ll start the review by checking out […]

Yundoo Y8 (Rockchip RK3399) TV Box Review – Part 1: Unboxing and Teardown

Rockchip first unveiled RK3399 hexa-core processor at the beginning of 2016, but we had to wait longer than expected to get devices to play with. The first retail product based on the processor is really Samsung Chromebook Plus, and we only saw a few TV boxes for pre-sale in January such as Yundoo Y8 or R-TV Box K99, and with the first shipments occurring in March. However, I’ve also noticed many companies postponed the launch of the RK3399 mini PC/TV box, and no company contacted me for review so far, so I had no rush because that probably means the boxes were not quite ready. But starting at the beginning of next month, more companies will start selling their model, and GearBest proposed to send me Yundoo Y8 model with 4GB RAm, 32GB flash, and decided to give it a go. In this first part of the review, I’ll only […]

Qualcomm Tricorder XPRIZE Selects Two Winners for Commercial Medical Tricorders

Healthcare takes around 10% of worldwide GDP, and while in some cases an increase in the healthcare to GDP ratio means better care for people, in other cases it may  lead to a decrease in the population’s living standards. There are political, business, and legal issues involved in the costs, but overtime I’m confident that technology can both improve care and lower the costs, in some instances dramatically, especially if open source designs become more common, and there’s some work in that respect with open source projects for prosthetics, opthalmoscope, and even surgical robots. Some commercial projects also aim(ed) to lower the costs of diagnosis tools such as Sia Lab’s medical lab dongle or Scanadu medical tricorder. The latter project sadly did not manage to pass FDA approval, and the company will stop supporting it on May 15, 2017, but that does not mean others have given up on developing […]

RDA Micro RDA8810 Android SDK with Linux & U-boot Source Code for Orange Pi 2G IoT Board Released

Orange Pi 2G IoT board was released a couple of weeks ago, shortly followed by Android and Ubuntu images, but since it was not based on Allwinner, but an RDA Micro  8810PL processor, we did not have any source code so far, which can be a real problem for a development board… Shenzhen Xunlong has now managed to upload a 6.7GB Android SDK to MEGA, with the link published via Orange Pi Resources page. MEGA has a download limit which depends on how much traffic they get at the time, and after 5.3 GB download,  I was asked to register for a PRO account, or wait for four hours before resuming the download. If you want to avoid this limit for any large MEGA download, you can run megadl instead. That’s what I did in Ubuntu 16.04 (remember to escape any special characters with \):

Once the download is […]
