Hey BadCaps crew! ⚙️⚡
Weekend tinkerer turned full-on “if it’s broken, I’ll open it” kind of person 😅
I’m into everything that can be taken apart, fixed, improved, or occasionally turned into spare parts — mechanics, electricity, electronics, and all the messy stuff in between! 🔧🔩
Curious by nature, I love figuring out how things work (and why they suddenly don’t).
Super happy to join Bad Cap — a place where tech passion, creativity, and good humor all meet! 😄
Can’t wait to share ideas, projects… and a few glorious failures along the way! 😉Comment

Hello World... I'm new to the forum, my name is Charlie. I like to repair stuff rather than throw it away (unless its well past common sense to repair). I like to understand how our devices, that make our everyday life easy, work the way they are. And I enjoy electronic devices in general.Last edited by Cfpm_spot; 10-17-2025, 10:34 PM.Comment
