[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 ...

Logic Noise is an exploration of building raw synthesizers with CMOS logic chips. This session, we’ll tackle things like bells, gongs, cymbals and yes, cowbells that have a high degree of non ...

It is worth noting that 3XOR logic gates are not manufactured by the industry. It will be shown below how 2XOR and 3XOR elements can be synthesized from a set of standard discrete elements. Figure 1 ...

Why? I will explain, but first let me say to those who have been playing with this puzzle: (a) You can not use XOR gates and (b) there really is a solution. In fact, as “The Black Adder” would say ...

Figure 1: Robots emulating AND, OR, XOR gates and a half adder in a living animal. We then added N robots (EP1P2N architecture), N being activated if and only if both X and Y are present.
