of course no one makes bipolar computers .... understanding FETs without understanding the quantum stuff is pretty easy

- ChuckMcM 11y agoTell that to the PDP-8 on my dresser (it's all Bipolar TTL logic, but you are not wrong). FETs are a lot easier to understand in many ways, there is a reason they took over as the dominant semiconductor switching element :-). Although my favorite FET demo is a piece of surgical tube connected to a faucet, and a water balloon sitting on the tube as the "gate". You can demonstrate all sorts of things like avalanche voltage (water flow regardless of the gate state), gate leakage (poke a small hole in your balloon), pinch off potential etc. Makes a great science fair project for you parents out there.
