I'm planning on building my first custom mod. I'm still doing a lot of research, but I plan on doing some sort of unregulated box mod for my first build. There are many extensive guides and walkthroughs out there on how to do certain builds, and I feel like I have enough tinkering skills and common sense to safely execute them. This dive back into electronics has me scratching my head trying to remember those electrostatics classes from years ago. I'm looking for a resource that is more than a reddit wiki and less than a textbook that pertains to battery safety and use, soldering, and designing/planning circuits. I'm finding so much good stuff on this forum already! Y'all are great!
