i actually want to create one for a PDA because i figured it would need less code and a little simpler than a PC one..i was actually thinking about doing it for a project...i just dont know how i can...

so what kind of skills do you need and most importantly what topics are most vital in creating it..i want to know if i can manage to create something very simple..thank you

am wondering how i can go about creating a simple operating system for a PDA device..can anyone help me and tell me if it is possible and the requirements for it..and also how i can go about...
