I’m often writing about Android / Linux mini PCs, but in this post, I’ll cover a mini camera: Polaroid Cube (POLC3).

FVIEW U2 Rockchip RK3188 Media Player with 2GB RAM, Ethernet, and Camera Sells for $53

If you are looking for deals, when new products come to market, older devices are usually sold at a deep discount, and sometimes you also have the advantage of getting a firmware that has gone through various iterations, and that’s more stable than the ones pre-loaded on new devices. We’ve already seen MK813 quad core TV box selling for less than $50, but it lacks Ethernet, and today I’ve been informed of another Rockchip RK3188 device with similar specifications but with an Ethernet port called FVIEW U2 that’s currently selling for $53 on Buyincoins. FVIEW U2: SoC – Rockchip RK3188 quad Cortex-A9 CPU @ 1.6 GHz + Mali-400 MP4 GPU System Memory – 2GB DDR3 Storage – 8GB NAND Flash + SD slot (Up to 32GB) Connectivity 10/100M Ethernet WiFi 802.11 b/g/n with external antenna Bluetooth 3.0 Video Output – HDMI Audio Output – HDMI + optical S/PDIF Video Codecs […]

TP-Link TL-WDR7500 (Archer C7) 802.11ac Router Review

With several new Android devices coming with the latest 802.11ac Wi-Fi, I decided I should buy a new router with AC1200 class or greater and Gigabit Ethernet support, and with a budget of $100. Xiaomi Mi Wi-Fi Mini router almost matched my requirements, but unfortunately only comes with Fast Ethernet ports. TP-Link Archer C7 selling for $96 Amazon US exactly matched my budget, and outmatched my requirements being an AC1750 router with 5x Gigabit Ethernet ports, and two USB ports. Since Amazon won’t ship to my location and shipping would have gone over budget, I expected to find it locally for a slightly higher price, but it ended up selling for over $200 here, allegedly because of a lifetime guarantee. Finally, I ended up buying TP-Link TL-WDR7500, the Chinese version of Archer C7 with 6 Wi-Fi antennas instead of 3, for $94.32 including shipping on Aliexpress. I’ll take some pictures […]

Firefly-RK3288 Development Board is Now Available for $189

Three days ago, a T-chip representative informed me privately that Firefly development board (Rockchip RK3288) would not be available on foreign websites, and that it was unclear when the board would be selling in China. So either I’ve been lied to, or there’s poor internal communication within the company, as they’ve now listed Firefly-RK3288 board on Taobao for 800 CNY (~$130), and it’s also available on GeekBuying for $159 including shipping, possibly by somebody unrelated to T-chip, especially there are only 3 units for sale. Let’s go the specifications that have slightly changed since the original announcement: SoC – Rockchip 3288 quad core ARM Cortex A12 / A17 up to 1.8 GHz with Mali-T764 GPU supporting OpenGL ES 1.1/2.0 /3.0, and OpenCL 1.1 System Memory – 2G DDR3 Storage – 16 GB eMMC flash + micro SD slot Video I/O HDMI 2.0 up to 3840×2160@60p VGA out (D-SUB connector) Dual MIPI, Dual LVDS and and EDP […]

Linaro 14.09 Release with Kernel 3.17 and Android 4.4.4

Linaro 14.09 has just been released with Linux kernel 3.17-rc4 (baseline), Linux 3.10.54 & 3.14.19 (LSK), and Android 4.4.2 & 4.4.4. Linaro has kept working on their member boards such as IFC6410 (Qualcomm), D01 (Huawei/Hisilicon), Ardnale (Samsung), and Juno (ARM). They’ve also announced they’ll change the tools to build GCC by using cbuild2 instead of cbuild1 for next release, and they’ve enabled a build with gcov (for code coverage analysis) which may mean they’ll work on reducing the kernel size by getting rid off unused code. I’ve also noticed the Arndale and Arndale Octa Ubuntu images are now based on Linux LSK with Mali GPU support since last month. Here are the highlights of this release: Linux Linaro 3.17-rc4-2014.09 GATOR version 5.19 updated topic from Qualcomm LT (ifc6410 board support) and HiSilicon LT updated Versatile Express ARM64 support (FVP Base and Foundation models, Juno) from ARM LT. updated Versatile Express […]

Test Your 4K Device True Resolution With a 4K UHD / 2160p Video Test Pattern

Now many products are sold on the market advertising 4K video output, but how to test and check if it just a lie with only part of the system support 4K (e.g. physical video output), but the rest of the system makes you lose quality? When I worked on DVD players, we had some special DVDs with video pattern allowing us to test different video quality. You can read about different video test patterns in “AVSHD 709 DVD document“. There are also some expensive equipments such as DVDO AVLab TPG – 4K Test Pattern Generator that generate test patterns to calibrate video equipments, but if all we want to do is to check the resolution has not been tempered with there must be a cheaper and easier way. After having a discussion about this issue on Google+, Dan Car decided to create a 2160p (3840×2160) test pattern image with some […]
