Qualcomm Showcases 4K LTE HDMI TV Streaming Dongle

There are now many wireless display adapters supporting Miracast, EZCast, DLNA, Airplay…, and streaming videos from your smartphone to the TV over Wi-Fi in 720p or 1080p resolution. Qualcomm recently unveiled a prototype called “4K Stream Adapter (4SA)” that does about the same but instead support 4K UHD resolution, and allegedly supports LTE thanks to its Qualcomm Snapdragon 800+ processor. According to a PCWorld report, Qualcomm mainly expects the device to be used to stream 4K video captured with a phone to a 4k UHD television, but it might also ending up supporting online video services such as Netflix, and mirroring your mobile device’s display onto the big screen. It’s also said to use a “basic Universal Plug and Play protocol” to connect with other devices, and the company is working to support communication with media apps such as BubbleUPnP, VLC and MXPlayer. Currently 4SA is only a prototype to […]

Add GPIOs to Windows, Linux, Android Computers and Devices with FTDI USB Adapters / Breakout Boards

It’s possible to to add GPIOs to your computer, (openWRT) router, or Android tablet using some FTDI USB dongles that expose I/Os. On operating systems based on Linux, including Android, you can use the GPIO sysfs interface (/sys/class/gpio) to easily control GPIOs from the command line, and in some cases Rx, Tx, CTS, .. pins can also be used as GPIOs. Zoobab has tried it with various FTDI USB adapters, and Oneping OP-1010 breakout board based on PL2303 HDX chip, and the results are mixed, but it could worth a try. There are currently patchsets ([1] and [2]) awaiting acceptance to mainline kernel that will enable GPIO support for these USB devices, but in the meantime you need to patch the kernel yourself, and then enable the relevant options in the kernel config for example “USB_SERIAL_PL2303_GPIO” or “USB_SERIAL_FTDI_SIO_GPIO”. The first patch is for PL2303 chips, and the second for FT2xxx/FT4xxx […]

Patched Android 4.4 SDK Supports Beelink R89 & Hotack T031 Boards

The first batch Tronsmart Orion R28 Pro/Meta Android TV boxes where ships with a micro SD card loaded with Android 4.4 SDK, so I tried it myself, and posted instructions to build an RK3288 Android image, but when I flashed the image to my device, I quickly realized it was an older firmware (106k4), so the SDK would not be so useful, since all the recent bug fixes were not included. Luckily, more recent Android 4.4 SDK were released or leaked, and naobsd decided to port it to Hotack T031 and Beelink/Netxeon R89 boards that are found in many RK3288 Android TV boxes. Since he does not own any devices based on Netxeon R89, he asked me to try, and I did so on Tronsmart Orion R28 Meta. Bear in mind these are images built from a patched SDK, so not everything may work, there’s no Google Play Store, and […]

$50 UNI-T UT61E Digital Multimeter Supports Data Logging to a Windows Computer

Since I don’t use a multimeter that often, and don’t need high precision, I bought an ultra cheap multimeter (Sunwa DT830B) locally a couple of a years ago. I normally use it for continuity testing (no beep though) for repair work / checking solder point, and some quick voltage measurement, and it works well for these simple tasks, although the lack of buzzer makes it a little inconvenient. But I discovered its limits when I tried to measure current. The 200 mA range works fine, but I started to encounter issues when switching to the 10A range, as device under tests would just start rebooting if the current draw was too high, and the manual indicates that you “cannot measure more than 15 seconds in the 10A range”. Since I did not want to spend $100+ on a Fluke multimeter, I did some research for a better multimeter, and finally […]

Updated Android 4.4 Beta and Ubuntu Images for pcDuino8 / A80 OptimusBoard Boards Released

pcDuino8 and A80 OptimusBoard are the only two Allwinner A80 development boards currently “somewhat” available, and albeit the PCB color is different, every else is basically identical, and pcDuino8 firmware should probably run on A80 OptimusBoard and vice versa. If you own any of these boards, you may interested in two images, one with Android 4.4 (beta), and one with Lubuntu, recently released by pcDuino / Linksprite. Android 4.4 (beta) 2014-10-08 – sun9iw1p1_android_optimus.img to be flashed with PhoenixCard (Windows) or Livesuit (Linux) Lubuntu 14.04? 2014-10-08 is comprised of two files: Kernel – pcduino8_kernel_livesuit_20141008.img to be flashed with PhoenixCard or Livesuit first. See instructions to use Livesuit with A80 OptimusBoard. Rootfs – pcduino8_ubuntu_20141008.rar. First extract the rar files to the root of an SD card or USB flash drive. There should be two files: pcduino8_ubuntu_20141008.img and update.sh. Now connect the mass storage device to pcDuino3 / A80 Optimusboard, and reboot the […]

Mini PC Polls: Networking Connectivity, Video and Audio Outputs

It’s always interesting to find out how people use their devices, and I recently discovered Google+ support Polls as Droidmote posted a poll to find out whether people used Wi-Fi or Ethernet with their mini PCs, and I followed up with polls about video and audio outputs. Around 50 people have answered to each poll up to now, so even if it may not representative, let’s have a look at the results so far. About half of the people are connected via Ethernet, and the other half are using Wi-Fi after 43 votes. Wi-Fi is normally more convenient, but may not be as reliable, and for users playing high bitrate videos Ethernet is a must, unless you find buffering enjoyable…. After 58 votes, most people still connect their mini PC to a Full HD television via HDMI, with a few connecting it to a 4K UHD TV, and nobody using […]
