Add bonus script: kindle-display

[dennisreimann]

Added my Bitcoin Status Display. Let me know if this needs more documentation or integration.

Tested ACK

But without a btcpayserver there is no price displayed.

It uses a Firefox to render out (via cron every 5 minutes) the png file for the Kindle. Seems a bit heavy for the task.
But works on my 2GB Ram Raspberry Pi.

This is great, but setting up the Kindle is far from trivial (just taking a break from trying to make usbNetwork work ). Will make some notes if succeed at some point.

I'd like to suggest to put it in the SETTINGS menu with the other display related things.

Testing:

./XXsyncScripts.sh kindle-display dennisreimann
./config.scripts/bonus.kindle-display.sh on

Yes this was super hard, you need to find the right thing for the model and firmware version. It took me like 2 hours. Already forgot how I did it (was 4 weeks ago).

I'd like to suggest to put it in the SETTINGS menu with the other display related things, rather than listing in SERVICES with the 1 click installs.

@openoms Ok, thanks for your suggestions. As discussed I'll leave this out of the menus as it is hard to seet up and I don't explicitely want to advertise usage of this. The main purpose of adding it was that some people were asking for it and it will make their life easier :)

Also added your notes to the main README of my repo, others might find them helpful when setting up USB networking.

I consider this finished for now – it is also using a fixed version of the app instead of pulling the master branch on install.

After getting this work initially now I only have this image generated on my RPi:

Node version is: Node.js v12.16.3.

Tried reinstalling, restarting, but not sure what is wrong.

@openoms this looks like the initial data could not get generated. Not sure why this might have failed. I tried running off/on and for me it worked, but I'll submit a fix PR that ensures the file is there so that the server can start.

Addressed in #1316

Just thought I would comment that this is working well for me too. I had some trouble with the USBNetwork setup, even with @openoms extra instructions that you added. This is what I eventually found and was successful with (https://www.mobileread.com/forums/showthread.php?t=204942):

-     un-plug cable (if still plugged in)
-     toggle USBnetwork ON in launcher
-     plug the cable
-     kill any automation (or configure yours to do: )
-     sudo ip link set up dev usb0 (It may already be up)
-     sudo ip address add 192.168.15.201 peer 192.168.15.244 dev usb0
-     use the networking until your done (telnet 192.168.15.244)
-     un-plug cable
-     toggle USBnetwork OFF in launcher

@grnqrtr Thanks, I've added it to the README.

Also a heads-up for everyone: With #1321 and the kindle-display v0.4.0 I've refined this a bit more, which allows to choose the exchange rates and require outside connections to be done via Tor. Thanks @openoms and @csperle for the contributions that lead to this! 🍰
