Examining this circuit is actually quite interesting; looking at the details teaches you a lot about electronics. The current and resistance calculations part really caught my attention. After such intensive work, it’s nice to unwind a bit; I usually play basketball legends to de-stress. Playing is fun and a great way to clear your mind after a tiring day.

I completely agree with the Among Us Online author's assessment. A circuit that is not isolated from the 220V grid and controls a touchable device like an LED strip is extremely dangerous. This is not a small mistake but a fatal risk. Although the circuit is simple and cheap, it is not worth risking your life to save a few thousand dollars.

This is a textbook example of what not to do in power supply design—dangerous, inefficient, and agario totally unsuitable for real-world LED strip use.
