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 […]

Pyboard MicroPython ARM Cortex M4 Board is Now Available for $45

MicroPython is both a lightweight implementation of Python 3.4 programming language, and a board, aka pyBoard, based on STMicro STM32F4 ARM Cortex M4 micro-controller running Micro Python. The project had a successful Kickstarter campaign in 2013, and they’ve completed shipment of the perks to their backers last June. The company has now launched its own store, so let’s see the progress of the project. The board has been re-designed since Kickstarter campaign, but the specifications remains the similar, but with some extra I/Os exposed: MCU – STMicro STM32F405RG micro-controller @ 168 MHz with 1MB flash, 192KB RAM, and an FPU. External Storage – Micro SD card slot, supporting standard and high capacity SD cards Expansion Headers: 24x GPIO on left and right edges and 5x GPIO on bottom row, plus LED and switch GPIO available on bottom row 3x 12-bit analog to digital converters, available on 16 pins, 4 with […]

Rikomagic Announces MK902II LE Ubuntu Mini PC Powered by Rockchip RK3288 SoC

Rikomagic announced their MK902II mini PC based on Rockchip RK3288 in May, and which has started shipping recently for about $130. The company have now announced MK902II LE (Linux Edition) based on the same hardware, but instead of running Android 4.4, it’s running Xubuntu 14.04 with some virtualization technique that allows it to run x86 Linux programs such as Skype, and it can even support Wine to run Windows programs. MK902II LE specifications: SoC – Rockchip RK3288 Quad Core Cortex A12/A17 up to 1.8GHz with ARM Mali-T764 GPU supporting OpenGL ES1.1/2.0/3.0, Open VG1.1, OpenCL, DirectX11 System Memory – 2GB (Dual channel 64 bit DRAM controller) Storage – 16GB Internal eMMC with Xubuntu 14.04 preinstalled + micro SD card slot Video Output- HDMI (1080p), and AV output Audio Output – HDMI, AV output, optical output, or external USB audio card (not included) Connectivity – Gigabit Ethernet, 802.11 b/g/n Wi-Fi. USB – […]

Performance Comparison of Amlogic S805 and S802 Processors

Amlogic S805 is a quad core Cortex A5 processor for entry levels Android media players, S802 is a quad core processor with faster Cortex A9 cores clocked @ 2.0 GHz, and S812 is an upcoming upgrade of S802 with HEVC/H.265 hardware video decoding, and Gigabit Ethernet support. I’ve already written about the features differences between AML8726-MX, S802, S805, and S812, but since I now have some devices I can make direct comparison between S802 and S805. It’s quite clear on paper than S802 should be significantly faster than S805, so the only question to answer is by how much, but I’ve been asked to do it, and it could be a fun exercise. The hardware devices used for the comparison are two Android media players: EM6Q-MXQ for S805 and Probox2 EX for S802, and I used the results from three Android benchmarks: Antutu 5.1, Vellamo 3.x, and 3Dmark Ice Storm […]

openPicus Introduces Wi-Fi and GPRS IoT Kits Powered by Microchip PIC24 MCU

openPicus has launched two new development kits for the Internet of Things with either Wi-Fi or GPRS connectivity, based on their FlyportPRO modules featuring a 16-bit Microchip PIC24 MCU, and sharing the same baseboard. These kits can be used as a Web server with firmware update over the air (FOTA) (Wi-Fi version only) among other things, and support TCP, UDP, FTP, & HTTP protocols, as well as MQTT (Message Queue Telemetry Transport), a light weight messaging protocol running on top of the TCP/IP protocol, used when a small code footprint is required and/or network bandwidth is limited. openPicus FlyportPRO Wi-Fi and GPRS modules share mostly the same specifications: MCU – Microchip PIC24FJ256GB206 16-bit MCU @ 32 MHz with 256KB Flash, 96KB RAM External Storage – 16Mbit Flash memory (for FOTA), 64Kbit EEPROM Connectivity GPRS Module – SAGEM HILONC GPRS Transceiver (quad band: 850, 900, 1800, 1900 MHz) with uFL connector for external […]
