Calibre on Raspberry Pi 3

[pckopp]

TL;DR Works fine.

I recently got a Raspberry Pi 3 (RPi3) and got it connected and setup. I did a standard install of Raspian Pixel, updated the firmware and OS to the latest, and configured the wifi and bluetooth interfaces. I have an 8G Class 10 microSD card for the OS.

I was curious about running Calibre on it so I gave it a try.

'apt-get install calibre' seems to work fine. Calibre 2.5 was installed.

I used my Windows system to copy a big library to a USB 3.0 flash drive and mounted that on the RPi3. That library has about 2400 books of all different file types. It takes calibre about 21 seconds to start and bring up the main screen and be ready.

Calibre recognises my Kindle and transfers books without a problem.

I converted a 920K mobi file to epub and it took 20 seconds.
A smaller 400K took longer, about 40 seconds.
CPU peaked around 60% during the conversion. OTOH, conversions on my Win10 i7 system with a fast SSD and lots of memory aren't blazingly fast either.

The RPi3 seems to have enough oomph for this. I have calibre open and idle, the File Manager open, the Chrome browser open with tabs for Facebook, Twitter, and Mobileread. The CPU meter varies between 15 and 20%.

Seems fine to me.

Happy holidays everyone.

Hi,

just having installed calibre on my Raspberry Pi 3 aswell.
Have your tried to download news?
Does it update the recipes when you use ebook-convert on the console?

Lets say you want to download NY-Times I type in the console:

ebook-convert "New York Times.recipe" NY.epub

and I get:

InputFormatPlugin: Recipe Input running
Trying to get latest version of recipe: nytimes_sub
Failed to download recipe, using builtin version

On my MINT Linux and Windows computer it works.
What can be the reason? Do you encounter the same?

I had not done that before so something new for me.

Your command did not work for me. It generated a huge list of data and I think the RPi3 got overwhelmed. Started out fine but then started generating a lot of errors. Finally quit with a segment fault. That looks like it would generate quite a large return file.

I tried something simpler.

ebook-convert "New York Times Technology Beat.recipe" NY.mobi

This worked and created a NY.mobi file that is perfectly readable. The file is only 84K.
