NickelMenu: An integrated launcher for Kobo eReaders

[Aleron Ives]

As far as I can tell, Kobo's battery meter has significant drift based on your charging habits. If you try to follow the guidance of keeping the battery between 25 - 75%, the meter starts to think that 75% charged is 100% charged, because it never goes above that point. I now have a > 20% disparity between what the battery icon reports and what the voltage indicates about the charge level. I'll try doing a full charge next time to see if I can get them to line up again.

I've been playing around with it off and on on the Clara HD, and it looks like the values that it has are:

-rw-r--r-- 1 root root 4096 Jun 7 09:47 uevent
-r--r--r-- 1 root root 4096 Jun 7 09:48 status
-r--r--r-- 1 root root 4096 Jun 7 09:48 time_to_full_now
-r--r--r-- 1 root root 4096 Jun 7 09:48 capacity
-r--r--r-- 1 root root 4096 Jun 7 09:48 voltage_now
-rw-r--r-- 1 root root 4096 Jun 7 09:48 voltage_min_design
-r--r--r-- 1 root root 4096 Jun 7 09:48 type
-r--r--r-- 1 root root 4096 Jun 7 09:48 time_to_empty_now
-r--r--r-- 1 root root 4096 Jun 7 09:48 temp
-r--r--r-- 1 root root 4096 Jun 7 09:48 technology
-r--r--r-- 1 root root 4096 Jun 7 09:48 present
drwxr-xr-x 2 root root 0 Jun 7 09:48 power
-r--r--r-- 1 root root 4096 Jun 7 09:48 health
-r--r--r-- 1 root root 4096 Jun 7 09:48 current_now

Unfortunately, no voltage_max or charge_full.

I have obviously missed doing something basic in trying to set this up on my libra 2. What am I doing wrong?

My guess would be that you copied the script into a text editor that uses Windows line endings (CRLF), instead of Linux line endings (LF). You need to use a different text editor, such as Notepad++, to convert the script to Linux line endings. I use MadEdit for such purposes, myself.

I did use notepad++ but will check the line endings. Thanks.

Edit: Telnet to my libra 2 shows the file structure to be similar to the Clara HD listed a couple of posts above.
