[IMSAI Guy] grabbed an obsolete XOR gate and tried a classic circuit to turn it into a frequency doubler. Of course, being an old part, it won’t work at very high frequencies, but the circuit is super ...
When designing logic for higher-than-usual supply voltages, suchas 24V, you can use a voltage regulatorwith a standard logic family and interfaceit through level shifters.Alternatively, if the logic ...
To demonstrate how computers work, [Alex Gorischek] has made a physical example of how binary logic gates work using pulleys and weights. For anyone who doesn’t know much about logic gates (Wikipedia) ...
