Offline Wikipedia on the Kobo
I often use my Kobo Clara HD where there is no WiFi available and the included offline dictionaries aren't always sufficient. So it would be nice to be able to look up words or names of people mentioned in the book on Wikipedia. With an internet connection the default Kobo firmware allows you to do this by long-pressing and then selecting the Wikipedia icon. So it should be possible to setup Kiwix with an offline copy of Wikipedia and use that instead. As it turns out it is possible with a few hacks. After a little research I found that a3nm did something similar in a blog post from 2013, which is a bit outdated now though.
This article assumes that you have access to the Kobo's internal files, either through a root shell using SSH or Telnet or by taking out the SD Card and that you are using a Unix operating system. Before doing anything make sure you have a backup.
You will need to download a Wikipedia ZIM-Archive of your choice from the corresponding page. I used the English "all nopic" version, which is 38GB as of writing this and will therefore require an SD-Card upgrade.
