As someone who is using the Raspberry Pi professionally, I'm nervous when I see that rainbow square in the top right corner in both their screen snapshot and the video (0:16 in). It's a sign that the Pi doesn't get enough power which might results in an unstable operation or even SD card corruption. I hope there's still a human backup sorter should the system fail :-)

My Raspberry PI corrupts data if the power goes out unexpectedly. I don't understand why it's used for any non-hobbyist application, at least if using the internal SD card to do a lot of read/write. I got myself a fanless cherry trail based system to replace it. Some guy did a hardware modification to fix his: http://therandomlab.blogspot.com/2014/04/how-i-solved-my-sd-card-corruption.html http://therandomlab.blogspot.com/2014/04/how-i-solved-my-sd-...

  I fully agree. That's why I've invested lots of work into my digital signage os (https://info-beamer.com/hosted https://info-beamer.com/hosted): It's booting into a read-only squashfs that contains everything. The squashfs, kernel and PI firmware itself are on the read-only FAT partition. All data that is required as display content ends up on a second read/write partition. If there is any data corruption or similar problem, my system can fully restore that automatically. Here's a small blog post were I wrote about this: https://info-beamer.com/blog/building-a-reliable-raspberry-pi-distribution https://info-beamer.com/blog/building-a-reliable-raspberry-p.... So far the system has never had any problem from power loss or cutting power. Interesting hardware hack you linked there. I haven't seen that one before. Thanks.

  Perhaps you'd have better luck using "industrial grade" SD cards; should have more robust firmware.
