Well if you connect two candles together (“A” and “B”), that would make a NAND gate already, with lit being 0.

To connect two of these candle NAND gates together, you’d have to make sure it wouldn’t burn in reverse though. I’ll leave that exercise to the reader…



It's not clear how two lit inputs results in an unlit output or vice versa with that setup. How do you make that work?


How do you imagine them being connected?
