Here is a Web site by a guy who designed working versions of all the basic logic gates, that is the NOT, OR, NOR, AND, and NAND gates, with Lego blocks.

Lawrence Livermore National Laboratory scientists and engineers combed mechanical computing with 3D printing to create “sentient” materials that respond to changes in their surroundings, even in ...

A logic gate is an electronic component (or set of them) that performs a logic operation, in which the binary values 0 and 1 are represented with two different voltage values, as seen in the previous ...

A hybrid computer uses rotating mechanical beams for memory and electrical contacts for logic, performing reprogrammable computation through physical motion in environments where conventional ...

Before we plunge headfirst into the fray with gusto and abandon (and aplomb, of course), let’s remind and reassure ourselves that—although the following discussions focus on the devices and ...

Digital gates are fundamentally analog in nature. They use transistors. Sure, these transistors are operated at their conduction extremes (which is why they are called “digital”), but during the logic ...

One of the hardest things about studying electricity, and by extension electronics, is that you generally can’t touch or see anything directly, and if you can you’re generally having a pretty bad day.
