DIY-arcade VS abracabra

Here are three hobby projects I've worked on during the last 2 years. I've written extensive guides for all of them:

https://github.com/maxvfischer/DIY-CNC-machine A CNC-machine I built from scratch, using 40x 3d-printed parts.

https://github.com/maxvfischer/Arthur An AI art installation I built from scratch using a GAN network, Samsung The Frame, a button and a PIR-sensor.

https://github.com/maxvfischer/DIY-arcade A full-size Arcade Machine I built from scratch.

Here's an extensive guide I wrote a couple of month ago of how to build your own full-size arcade machine from scratch: https://github.com/maxvfischer/DIY-arcade

An automatic Zen Garden drawing infinite patterns in sand. Using stepper motors, inverse kinematics and a Raspberry Pi Zero W (including, code, images and tutorial). I'm almost done building the robot, but still have quite some implementation to do. Also, the guide is far from done, I've mostly uploaded images so far.

Yes, I plan to set this one up with an old computer running retro pie for the software to donate and I will build a second one for myself using a Raspberry Pi 4 also running retro pie. Original inspiration comes from this amazingly well documented build: https://github.com/maxvfischer/DIY-arcade

Half-baked as in eating it can cause gastric problems, not as in 50% done?

https://github.com/hadrianw/werf a graphical mouse driven text editor inspired by Plan 9's acme. It can open quite big files, you can WIMP around a bit, but README is just wishful thinking, it can't even save files. Written in C with cairo and fontconfig. Currently for a few years I'm in process of rewriting text buffer, I have something nice, but did not test it enough and did not integrate it. Now I'm thinking of a rewrite in Zig to learn it and also make it easier to test. But that's my wishful thinking again.

https://github.com/hadrianw/tomatoaster a ChromeOS like Linux distribution based on Void Linux build system, AB partition scheme, building squashfs image without root privileges. Currently I did a nice and almost proper script to handle it and do not need to patch as match to build an image, that runs, but is not entirely useful. Need to clean-up the script and commit. Mostly bash, bunch of patches and config files and a bit of C.

https://github.com/hadrianw/abracabra a search engine, that will not index pages with ads (all results would be uBlock-Origin clean), that is not yet even a proper pipeline to check whether a page does contain ads or not, no crawler yet at all. I want to go through Common Crawl archives first. I did something in Go first (https://github.com/hadrianw/abracabra-legacy), but now I'm rewriting it in Rust, because of awesome lol_html crate, that will make filtering fast and easy. Currently writing code to filter URLs with Rabin-Karp and a bit of loops. It created an e-mail thread years ago with people wanting to help, but I've been too slow.

I don't want much help to code things, I would appreciate however a bit of pointers on a couple of things regarding Rust and watchdogs (to recognize a partition as unbootable and reset the system to the previous partition).
