I share hands-on demonstrations and educational content focused on electronic and mechanical repairs. You'll learn how to diagnose and fix a wide range of issues using simple, affordable tools—like basic voltmeters and handheld oscilloscopes. I also dive into vintage electronics, showcasing how these classic devices work and exploring how we used them decades ago. Whether you're a beginner or a seasoned tinkerer, there's something here to spark your curiosity and build your skills.
