Integrated circuits shrank transistors dramatically, and this trend continued from the first example in 1959. Just twelve years later, in 1971, Intel announced the 4004 - a four-bit processor that was ...

Horrible Science fact It's all well and good having a perfect, simple circuit but it it includes a switch, it will only work if the switch is in the on position meaning the circuit is closed. You ...

Also, the known J-and D flip-flops first needed to use an anti-glitch R-S circuit, making the design too complex. So, I tried a simple circuit using a 7402 quadruple NOR gate (see the figure).

Play dough circuits 2: experiment with electricity Last time, we went through the basics of how to make simple electrical circuits with play dough and light-emitting diodes, now it's time to ...
