"Electricity-Free Computer Logic Spinning Innovation"

The Action Lab demonstrates making logic gates from chains and gears, using Spintronics as a commercial toy example, and highlighting the analogies between mechanical components and electric current. The setup includes a spring wound motor as a "battery," gears as resistors and junctions, and switched gears as inputs, showcasing the potential for creating chained inverters, NAND gates, and NOR gates. While unwieldy in practice, the concept illustrates the possibility of mechanical computing and the idea that everything can be viewed as a logic gate.
