Qualcomm Showcases 4K LTE HDMI TV Streaming Dongle

October 21st, 2014 5 comments

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,…

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

October 20th, 2014 12 comments

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…

Patched Android 4.4 SDK Supports Beelink R89 & Hotack T031 Boards

October 20th, 2014 No comments

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…

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

October 19th, 2014 12 comments

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,…
