Hi, I’m Sikyong. This channel delivers practical electrical engineering education: basic circuit theory and simulations, PLC programming with Siemens S7-200/S7-1200, and electrical cabinet design using AutoCAD & EPLAN aligned with IEC/TCVN standards. I also share tips and walkthroughs for selecting, installing, and maintaining genuine licensed software to keep your devices secure and reliable. To balance study and work, enjoy curated music—focus beats, chill instrumentals, and uplifting tracks.
