Welcome! This site is a collection of my automotive projects, technical research, and documentation. Having spent countless hours digging through forums and websites for specific technical details or explanations, I know how difficult it can be to piece together reliable information from scattered sources. I also know how valuable it is to find someone who has taken the time to document what they've learned and make it available to others.

I don't expect you to take everything here at face value. My goal is to share what I learn, explain my reasoning, and cite the sources behind it wherever possible. Over time, I hope to build a useful collection of information that helps others working on similar projects.

If you'd like to learn more about me, visit the about page. Otherwise, feel free to explore my projects, browse the technical library, or take a look through the gallery.
