Thanks, I didn’t know any of this.

I just started a hobby project with Bun, it’s my first time trying it. I would like to know what you are referring to when you say “what Bun did”. Can you share more information?

This might not be your issue, but it might be useful to know: if you connect two disks with the same GPT UUID, they might start misbehaving. Perhaps GRUB might not care, but Linux does. Did you ever clone a disk or partition without changing the UUID?

Can I do a shameless plug? Not necessarily all of these are my favourites, but most of these are pretty nice. Here’s my list.

My top fav is Mindustry, which has already been mentioned. Another not very popular FOSS game which is pretty good imho is OpenClonk.

(Personal opinion not based on scientific evidence.)

I would say that’s not possible for a hobbyist. The main issues with this kind of DIY phones are performance, compatibility with existing software, and most importantly battery life.

The Raspberry Pi was never designed to be used with a small battery while still staying connected to the internet to receive notifications all the time, like a smartphone. If you want to build a usable smartphone you will need an efficient co-processor to do these tasks. This could get complicated fast unless you use a CPU designed for this job.

There has been some interesting progress with desktop environments and small touch screens. Still nothing as good as Android, but nice UI is no longer the main issue imho.

As for compatibility, good luck running Signal, Matrix and Thunderbird in the background without draining the battery.

That being said, if you are just doing it as an excercise without expecting to build a device that will replace your main phone, you can definitely give it a try. Have fun and learn much!
