Tools Native kinfetch - neofetch for your Kindle

[lzampier]

Hey everyone,

I wrote a small neofetch-like tool for Kindle. It's a single static binary (~465KB) written in Rust. Just drop it on your Kindle and run it, no dependencies needed.

What it shows:

root@kindle
-----------
device: Kindle Basic 4 (2022)
os: Kindle 5.16.2.1.1
kernel: 4.9.77-lab126
resolution: 1072x2896
uptime: 1h 10m
shell: sh
cpu: ARMv7 Processor rev 4 (v7l) (2)
memory: 343M / 474M
disk (user): 4.2G / 13.4G (31%)
local ip: 10.45.2.49
tailscale: 100.114.118.55
battery: 46% [Discharging]

It identifies your device model from the serial number.

There's also a --full flag for debug/diagnostic info, handy when posting for help here:

kinfetch --full

Adds: serial (masked), board ID, WiFi MAC, firmware ABI (armel vs armhf), jailbreak method, battery voltage/temp, KOReader version, and installed KUAL extensions.

The name would have been "kindlefetch" but that's already taken by another project that... let's not talk about.

Feedback welcome!

Haha cool!

One suggestion: battery info might elaborate on how much total capacity is left in the battery. There is a KUAL extension called Battery Statistics. It shows percentage, current charge (mAh), temperature, and estimated total charge. Then it divides the current capacity by total design capacity to show “Battery Health”.

Might be useful here too. I’ll see if I get my hands on the laptop today, I can share those extensions I tailored for PA6 and Kindle Scirbe 1, they have slightly different units and file sources for the battery

Thanks a lot for your work!

My PW6 is reporting an abnormal temp report. I suspect it includes one decimal but no separator.

Also resolution seems too big?

[janton]

Yes, the resolution should be something like 1264x1680, or maybe some extra pixel, but not that big.
It's also too big in lzampier's Kindle Basic 4.

[janton]

Maybe it should be better to get the resolution from modes instead of virtual_size.

[root@kindle fb0]# cat /sys/class/graphics/fb0/modes
U:1272x1696p-0
U:1272x1696p-0

[root@kindle fb0]# cat /sys/class/graphics/fb0/virtual_size
1272,3392

It lacks a system icon
