Projects / The Cubietruck chronicles - Chapter IV: Android TV sequel

Hi Everyone! I'm back!!  8)

Now for (maybe?) the final chapter of Cubietruck chronicles, because some things changed and seems this time for good...

After a few months of working well, the DPF started to (once again) fail...  :-\
The image on the screen started to shake and move like some kind of interference, but it wasn't.
Something like this:


 
I tried different cables, input sources, but in the end it was the VGA to RCA video converter.
After wasting a lot of time trying to fix it, I realized this actually presented an opportunity, because...

1- To buy a new or even better video converter like HDMI to RCA for instance, would cost me the same as a new RPI 2 (sadly, at least that's it in my country).
2- Buying a new RPI would give me the chance to try the new model which I was hopping to.
3- By replacing my old RPI would left a spare board with native RCA video output to hook on the TFT monitor and that way build a new DPF.
4- CT would suit perfectly as an Android TV set on a 24" non Smart TV, and that way make it "Smart".
And that way make a much better use of CT, not just a picture album...

Now let say a little bit more about #4 since it's more of this board's concern. Items 1-2-3 will be for another day's (and board) topic...

As for hardware, I just get rid of everything but top and below acrylics and On/Off button. Just back to basics.
But I have to add a little piece of plastic between CT and top acrylic to make pressure over the board and that way avoid any unwanted disconnection or memory error as in the past.

In short, no more fancy stuff... almost like in the beginning.
But with an extra: a mini wireless keyboard that will fit just great with CT and that way have remote control of Android.

Here some pictures of the rig:






As for software, I downloaded and installed this image:

It already has Kodi, but I was more interested on Netflix and Spotify, along with Chrome and Youtube.
And for wallpaper a cool one called Device Info Live WallPaper:

Here a screenshot:



So that's it! Easy as pie!
Hope you liked it, and see you around!!  ;D

It is for CB2 and Android  ::)

Hi people!! :)

This is the next part of chapter III http://www.cubieforums.com/index.php/topic,3163.0.html
Acronyms:
CT = Cubietruck
DPF = Digital PhotoFrame
TFT = 7" TFT display

To continue on this, another step would be to add a power button bigger than the onboard power button which is too small to handle (even with Ewell case).

So I soldered two pins on the two holes located next to the onboard power button and from there I attached a push interruptor. It has two states, push once to close, push once more to open.

This was preferable to a push button because despite it will be needed to push twice to turn on or off CT, still will be easier than holding the button for a copule seconds, specially for an older person.

Here the pictures on how the button and VGA to RCA conversor were mounted on the acrilyc case:







These are pictures with the 12V fan attached to a side of the case, to push hot air away from CT and the bottom of the VGA to RCA conversor:





Here doing the final tests before to move it to its final destination:






CT is currently located over a computer desk, hidden behind an All in one computer. While the TFT is located nearby CT, on a shelf where former DPF was placed before. After booting on Android desktop and start XMBC, it has 1 minute of delay until slideshow screensaver finally starts, and 15 secs between random pictures.

CT can be turned off by pushing the interruptor, this action triggers a shutdown of the Android system.
And here a video showing how it's finally working (click to enlarge):



As a conclusion, I have to say that no matter how expensive this may look, in the end it has been a cool experience that took a year to be completed (considering from the moment I bought CT on november 2013 until now).

I also hope people have not been offended by this article, I now most of you are Linux fans and you hold high expectations on cubieboard products, specially CT since it is a product designed for much more interesting things than just a dumb DPF running Android...

But this situation is much better than keeping a u$s 100 paperweight, as it was until I came up with this "crazy" idea. In any case I can go and rescue CT anytime if needed, the only thing is to bring a better DPF to replace it...

But I have to thanks CT for all the good and bad moments. During this time a learned a lot from CT, from compiling driver modules on Linux to debug through serial port.
I hope you also have the fun of your lives with this product, or at least to have more luck than me!!

Thanks for everything and see you around! ;D

THE END... ?
