Paperwhite MOD: LED change to red or amber?
Anyone know of a replacement red or amber LED for the Paperwhite? Or maybe a source for a removable film that would slide over the screen and give a red tint?
The idead was to replace the white LEDs with red or amber ones. I've been doing a lot of reading in a dark room so as not to disturb my wife. I've also been told by my phsycian not to use an LCD or other backlight device in the evening so as to sleep better. On the rare occasion that I need to use my Linux machines, I use them with the Debian package redshift; it gradually changes the color temp of the LCD, elimintaing blue, as dusk evolves. |

This question has come up before. The last time suggested solutions included tinted overlay sheet and altering to an inverted palette. The touch-screen technology makes overlays impractical though.
The lightpipe technology makes led replacement impractical. IMHO Most teardowns feature the tiny little group of leds in some detail. The inverted palette is, by far, my favourite solution. Last edited by twobob; 08-11-2013 at 07:51 PM. |

I'm also interested in inverting the pallette.
I was showing someone my PW over the w/e and they asked if it was possible to display as white on black rather than black on white. |

There's a nice implementation for the Kobo that could possibly adapted for the Kindle: https://www.mobileread.com/forums/sho...d.php?t=212162

I was looking to invert the eink screen (black background / night reading mode) but couldn't find a clean solution for kindle online. Although I could not get kindle reader to invert colors, I found a solution others were using with Koreader. Here is what I did.
-JB, KUAL, USBnetworking (optional) -install Koreader -run Koreader for the first time to create a (/mnt/us/)koreader/data/cr3.ini file Then the aim is to do what trekk did here and modify the cr3.ini file: http://www.mobileread.mobi/forums/sh...=216960&page=9 switch the "crengine.display.inverse=0" from 0 to 1. This can be done manually and then Koreader will always produce a black background book with white text, or you can make a few changes to the Koreader files to create a toggle switch. A new file "koreader_night.sh" should be put in "/mnt/us/koreader/" which has the following lines (thanks muness): Quote:
Then add a toggle menu item to the Koreader menu.json file. Quote:
Now you can read in night mode on a Kindle through Koreader and you can toggle it on and off. Next step is to work out how to sync the book pages between Kindle and Koreader. Any ideas? Last edited by aconicq1; 02-03-2014 at 09:57 PM. |

Nah. It is usually more tricky to do it on Kindles (but then, they have a wicked, but working X11 server running), but I'm tempted to say that Kobos are a bit more hackable in general. Kobo isn't trying to scare independent developers away like Amazon does...

yeah, i don't know anything about kobo, nook hacking, but i can't see them putting in more effort than amazon. i'm worried in a way that, we won't be able to have nice little (and some not so little) customizations like the ones we do now, in the future
