It is painful, but it's not all lost. First, the 2.0 watchy that can be bought on aliexpress is pretty good already and I'm not comfortable with posting this for I think obvious reasons, but I'm working on an ideal watchy for me: https://github.com/Szybet/Yatchy
It won't be a commercial product or anything, it will be just a perfect watchy for people who want something better than 2.0
because it's mainline kernel something is broken across kernel -> driver -> fbink -> qt platform plugin and it's slow to draw things on screen. We are looking for solutions and have a few ideas already
Some kindles are locked up on cpu level for no reason - fuck amazon
Apart from that, nothing really. Most often people just start to port devices, we help them and one day they dissapear wasting our time and effort :(
3 devices are being currently ported, anyone who has a ereader can come in and try to port it. Only time is needed, we can help with the rest.
The only device that we couldn't port was the first sony ereader because some weird cpu watchdog ressetted the device after boot - so our knowledge was limited on a complicated device
The device also needs kernel sources to be released for it, but kobo and kindle do release them ( sometimes after complaining ) so thats fine too
There is no minimum spec. It runs on a kobo mini 800 mhz 1 core cpu and 256MB of ram and lags a bit. On a kobo nia which has 1 Ghz 1 core 256 MB ram it's fine
As I stated in the FAQ, even more performance could be traded for disk size, with a bigger sd card
The system is really hackable, for example: It has xorg ( It's not super stable but yea ), an alpine rootfs so a package manager. I added USB support to it ( hot pluggable, which is not possible on the stock OS, if at all ): audio, mouse, keyboard: https://github.com/Szybet/niAudio
I was interested in writing apps for my ereader. It was stupid for me that every app on the stock os ( Koreader, plato, Obenkyobo... ) has to implement their own sleep manager ( A developer in the community, Aramir still has nightmares after it ), wifi etc. Now InkBox and it's background services manage that.
It's stable as hell: There is a recovery mode in which you can export the whole SD card over USB, enable on screen boot logs. The system is immutable which helped me many times.
Once again, apps: We use musl and glibc so we are not limited by either one ( postmarketOS guys have problems running koreader because musl ). We also provide some ereader friendly libraries, a easy to use Qt toolchain ( I ported many Qt apps, with more or less success. The ones that are an official app are: feathernotes, rssguard, nachat, maps. The ones i gived up on: Marble, Okular )
We fix things broken on the main OS: At least for my kobo nia I made the touchscreen a kernel module and reset it every sleep / wakeup to prevent a lockup which happened to me on the stock OS. It also sleeps now in and doesn't wake up, so better battery life in sleep. On every wifi connection it synces time, it drifts a bit.
We have a reader up but it's not great. A rewrite is ongoing, will finish this year for sure. It won't be better than koreader for sure, we don't have 200 developers but it uses Qt, which enables us to use better looking UI than simple menus like Koreader / Plato.
Oh did i mention we have koreader as a user app? you can use it ;)
Yes, most or many of those things could be done on the stock OS - but no one did it for a simple reason: you want to control things or there will be chaos.
As for now, InkBox is mostly an app launcher for me, but I really like it for it. No more stock OS resets :)
For the average user? if you are not interested in those apps, in not hacking your ereader, not doing something unusual with it InkBox is probably not interesting for you. But if you use koreader anyway, dislike the stock OS and like open source, you are welcome.
We are also looking for contributors ( Rust / C++ or anything really ), this project has more potential than it seems
I updated the post with an official response
