Power Consumption of Amlogic S812 and Rockchip RK3288 TV Boxes

The recent post comparing the power consumption of ODROID-C1 vs Raspberry Pi boards, as made me want to give another try at power consumption measurements. Regular reader already know I made a power measurement board and cables capable of hading different connectors (micro USB, mini USB, power barrels,  etc..), but eventually it failed to deliver enough current to the boards for any meaning testing. But since I now have a better power supply, and multi-meter, it was worth another try, especially since I could draw some pretty charts. I decided to test the three most popular Chinese SoCs for mini PCs namely Amlogic S812 (4x Cortex A9), Rockchip RK3288 (4x Cortex A17), and Allwinner A80 (4x Cortex A15 + 4x Cortex A7) using respectively Eny M8S, Open Hour Chameleon, and A80 OptimusBoard. If you are paying attention, you must have noticed Allwinner A80 is not part of the title, that […]

Review of Zidoo X9 Android Media Player and Video Recorder

Zidoo X9 is quite a unique product on the market, as it’s the only low cost Android platform that I know of that features an HDMI input port with recording capabilities. The hardware is actually based on Kaiboer F5, with some modifications, but the latter focuses on the Chinese market, while Zidoo X9 targets oversea markets with an English firmware by default. I took pictures of Zidoo X9 and its board about a month ago, but a busy schedule and some initial issues with Google Play Store delayed the review. Finally, I’ve completed testing of the device, and ready to share my findings about performance, stability, and features in this review. OTA Firmware Update I’ve had to go through two firmware updates before carrying on with the review, and this part is working great, and they even include a detailed changelog with each release, which they also publish on their […]

Linux 3.19 Release – Main Changes, ARM and MIPS Architectures

Linus Torvalds released Linux Kernel 3.19 yesterday: So nothing all that exciting happened, and while I was tempted a couple of times to do an rc8, there really wasn’t any reason for it. Just as an example, Sasha Levin used KASan and found an interesting bug in paravirtualized spinlocks, but realistically it’s been around forever, and it’s not even clear that it can really ever trigger in practice. We’ll get it fixed, and mark it for stable, and tempting as it was, it wasn’t really a reason to delay 3.19. And the actual fixes that went in (see appended shortlog) were all fairly small, with the exception of some medium-sized infiniband changes that were all reverting code that just wasn’t ready. So it’s out there – go and get it. And as a result, the merge window for 3.20 is obviously also now open. Linus Linux 3.18 improved performance of […]

Raspberry Pi Model B+ Can Now Be Purchased for About $30 Shipped

The Raspberry Pi maybe promoted as a $35 ARM Linux board, but in reality once you had taxes and shipping the price can be quite higher. For example on Element14 Thailand, I would have to spend 1,300 Baht ($40) + shipping,  or even 1750 Baht ($54) to get the board. But since Raspberry Pi 2 launch, sales numbers for R-Pi model B+ have most likely dwindled, and some sellers are trying to get rid off stock. Some deals I have found or been tipped off: $30.29 on Amazon US. Free shipping in the US on orders over $35. $31 including shipping on Aliexpress $33.99 including shipping on Bangood $37.81 including shipping on DealExtreme $37.88 including shipping on Ebay If you know of other better or similar deal for the Raspberry Pi Model B/B+, feel free to leave a link in comments. Thanks to Onebir for the tip.
