Installing and customizing CoreELEC in X96 Air

I previously installed CoreELEC on another TV Box (Ugoos X3 Pro), which unfortunately died after only 9 months during the summer (due to the unit overheating, which I learned is a common problem for cheap Android TV boxes). So this time I purchased a X96 Air (4GB/32Gb) and had to do the whole thing again.

So this is a note-to-self in case I ever have to install CoreELEC again on some other device.

Installation of CoreELEC is simple enough by following this guide. Basically, it involves downloading and writing the firmware to a microSD card using usbimager. Then insert the microSD card, reset the unit and hold the reset until the logo appears. The unit will then proceed to boot into CoreELEC.

First thing is to connect to WiFi, then enable SSH. This allows me to login via ssh and execute:

ceemmc -x 

from the terminal. This writes CoreELEC to the built-in eMMC storage, after which I am able to remove the microSD card and reboot the unit into CoreELEC via the built-in storage.

Now here comes the bit that was tricky enough to get me stuck for quite some time. 

I am using a Mele F10 Airmouse, and CoreELEC was able to detect it automatically when the USB receiver was plugged in. However, I wanted to reconfigure the keymap such that during video playback, the left and right buttons will do forward and back stepping by 10s, and the back button will do stop the video. 

This can be achieved by adding /storage/.kodi/userdata/keymaps/keymap.xml:

<keymap>
  <fullscreenvideo>
    <keyboard>
      <left>stepback</left>
      <right>stepforward</right>
      <browser_back>stop</browser_back>
    </keyboard>
    <mouse>
      <mousedrag>noop</mousedrag>
      <mousemove>noop</mousemove>
      <rightclick>stop</rightclick>
    </mouse>
  </fullscreenvideo>
</keymap>

The back button on my airmouse will sometimes map to browser_back, and sometimes rightclick. I am not sure why, so I have mapped both to the command stop in the keymap file.

Also change System > Interface > Skin > Fonts to Arial based so that Unicode filenames can be displayed.

Don't forget Settings > Interface > Regional > Timezone country for the correct time.

Finally, my new TV box has a LED display at the front, and I was delighted this is supported by CoreELEC to display all kinds of info (date, time, CPU temperate etc.). This is configured by downloading the appropriate device VFD file as /storage/.config/vfd.conf (I used x96-max-1gbit-vfd.conf), and also to install the OpenVFD addon.

Update: Line adapter for Ozito Blade Trimmer

Update (Dec 2021): If you access to a 3D printer, I would now recommend this solution , which makes it super easy to replace the trimmer line. I have been using it for a few months now with zero issue.

Filament Joiner Part 2 (With Display and Knob)

Thanks to the current corona-virus crisis, the parts I ordered for the filament joiner project were taking forever to arrive. But now that they have finally arrived, I can put them to good use. These were the parts ordered: 0.96" OLED display SSD1306 Rotary switch encoder KY-040 Here is the final circuit diagram: The OLED display is connected to the SDA and SCL pins of the Nano (A4 and A5 respectively), and powered by 5V and GND. The rotary switch encoder is connected as follows: VCC => 5V GND = > GND CLK => D9 DT => D8 SW => D2 My prototype board now looks like this: The updated code for driving the knob and display is available in  heater-with-display.ino in the Github repository . We now have a fairly compact (about 7cm x 5cm) and independent filament joiner (no need to connect to PC) that is driven solely by a 12V power supply. Here's how to use it to join printer filaments. More usage details in my previous post .

Adding "Stereo Mixer" to Windows 7 with Conexant sound card

This procedure worked for my laptop (Thinkpad E530) with a Conexant 20671 sound card, but I suspect it will work for other sound cards in the Conexant family. I was playing with CamStudio to do a video capture of a Flash-based cartoon so that I can put it on the WDTV media player and play it on the big screen in the living room for my kids. The video capture worked brilliantly, but to do a sound capture, I needed to do some hacking. Apparently, there was this recording device called "Stereo Mixer" that was pretty standard in the Windows XP days. This allowed you to capture whatever was played to the speaker in all its digital glory. Then under pressure from various organizations on the dark side of the force, Microsoft and soundcard makers starting disabling this wonderful feature from Windows Vista onwards. So after much Googling around, I found out that for most sound cards, the hardware feature is still there, just not enabled on the software side. Unfortunately, to
