Saldiamo e testiamo un alimentatore fai-da-te ⚡️ kit da 4€ (Tutorial completo) Truffa o affare? 1/3

Video 1 (Part 1/3): In this video, we will assemble and test a small adjustable power supply kit that I purchased on AliExpress for only €2.29 (currently selling for €4). We'll see together if this DIY project is a real bargain or if the money has been wasted. I'll guide you step by step: from component selection, to soldering, to the final testing with some small modifications to make it more stable. It's a perfect project for those approaching electronics!
