Hey PH! I'm Tu, and I build electronics learning tools in Vietnam. The short version of why ManuStem exists: an Arduino starter kit here costs what many families spend on groceries in a week. So most kids never touch one. I spent the last year putting the whole lab in the browser instead — real avr-gcc compiling real C++, a deterministic circuit sim, and a 3D arena where kids race the line-followers they coded. The part I'm proudest of is the AI debug coach. Kids don't get "avr-gcc: expected ';' before 'delay'". They get told, in their own language, exactly which wire or line is wrong and how to fix it. It's Vietnamese-first (that's where the kids are), with an English toggle. Free taster with no signup — I'd love feedback especially on: does the first lesson make sense to a 10-year-old who's never seen a resistor? Happy to answer anything about the sim, the compiler setup, or teaching STEM without hardware.
