#2It's funny, but this could have been me. I also wrote a toy OS in 2001 and I learned by using many of the same resources you listed.
One thing that makes this all SO much easier these days is the Virtual Machine. I remember back in '01 I didn't really know much about them and so, everytime I wanted to test my OS, I would dd it to a floppy and then boot it on a crappy laptop I had lying around. I probably would have stuck with it had I used a VM and some scripts.

#3Xv6* is a good place to start studying the workings of a Unix-like operating system.

What would you say about writing an OS on something like an Arduino ? Without mucking with ASM, you could at least give it the ability to run multiple processes and implement some IPC. I've been trying to do something of the sort but I've got other high-priority stuff to get out of the way first.

#5The amount of amazing resources he has put into his repo along with the code is astounding.

#6Writing an OS kernel is a great experience. You will be a stronger programmer at the end.
Another good resource is CMU's course on the subject: http://www.cs.cmu.edu/~410/

#7Writing a toy OS is something that while seemingly intimidating, is actually pretty approachable. My mind was blown when I came across Lions' Commentary on UNIX as a HS sophomore, and I ended up spending the whole summer working on some dinky Unix'y clone.
I do OS development and most of my coworkers had similar experiences.

I've started building a webversion of Lions' Commentary,
maybe this is helpful for someone.

#9Back in the days I also managed to write a bootloader and handle interrupts from the keyboard. I found GeekOS to be a great source to learn from. I even contributed a patch. http://code.google.com/p/geekos/

It's a great idea. Having the OS run on a ROM directly would make things easier...
For me, the worst part of writing an OS to x86 is that you have to start with a bootloader, a primitive filesystem, change CPU modes... all that before you get to the fun part (memory management, threads, running programs, improving your filesystem). Then I discovered LILO and GRUB, but it was too late!
