"Component" pins are aluminum rod through brass shims.

Discrete NPN Transistor Demo.

Blue button applies "bias voltage"  to the collector and emitter.  Yellow button applies base current, and current can be seen to "flow"  -- depletion zones collapse around the P doped base and a tone is emitted.

Slider changes speed of current flow.  Slider knob is a large silicon crystal.  Transistor body 3D printed and handpainted (vintage TI yellow).

Discrete transistor collection inset.

Left panel is a walk through of binary numbers (top).  Below the break is a game that runs through binary numbers 1-15, using the four buttons.

Middle panel is an overview of how transistors combine to make logic gates, with three pushbutton gates.

Last panel is how gates combine to add two numbers.
