Hi, I’m Yopie — an electronics enthusiast and Senior RF & Microwave Engineer.
I’ve been passionate about electronics since middle school, and decades later I’m still experimenting, building, breaking things, fixing them again, and always learning.

Professionally, I work in high-frequency technology — from terrestrial radio links and satellite communications to radar systems — but this website is purely about my personal hobby projects. Everything here comes from hands-on experiments on my home workbench.

🎯 My Goal

Build more, buy less — and share the process openly so we can learn together.

Welcome to YopieDIY — and happy experimenting! 🔧✨
