This post documents the journey of building a Linux system on a custom PCB by someone with no prior experience. The text includes detailed steps on designing and programming the PCB, focusing on using the ATtiny chip and AVR Dragon for programming. Controversially, it criticizes reliance on off-the-shelf PCBs like Raspberry Pi and promotes DIY custom PCBs for better understanding. The process involves basic electronics knowledge and explores the challenges and solutions faced during the design and implementation stages. Surprisingly, the post encourages beginners to attempt creating their own Linux-ready PCB prototypes with a few hours of daily dedication.
