Series Expedition
Silicon Layer
Explore the silicon foundation of computing across three chapters — the transistor switch, logic gates, and the CPU datapath — as a 3D space where you flip voltages, wire up logic, and follow one instruction.
Suggested route
Follow a sequence that connects progressively deeper views of the same subject.
1/3 · AvailableTransistor
See a MOSFET cross-section where gate voltage opens a channel and switches the source-to-drain current on and off.

2/3 · AvailableLogic Gate
Combine switches into AND/OR/NOT/XOR and watch logic emerge as input toggles drive a live truth table.
18 min · 5 hotspots · 3 checks
3/3 · AvailableDatapath
Follow one instruction through fetch, decode, execute, memory, and writeback, mapped onto the Turing five phases.
