About Alex Chen
Alex builds things that make life simpler. Started with a broken Arduino in 2016 and never looked back. When not soldering, you will find him exploring local electronics markets or teaching neighborhood kids their first LED blink.
His lab runs on curiosity and lots of coffee. Every project here started as a problem he needed to solve—whether it was keeping plants alive during a 3-week vacation or knowing who is at the door without checking.
Alex believes the best technology disappears into daily life. No complicated apps. No subscription fees. Just working solutions that anyone can build.
