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 (W… ...

Pairs of gates can be used to create AND and OR logic based on the levels of output observed. When a pair of gates are both off, output is low; it's higher for a one-on/one-off situation (OR) and ...

Last week, MIT researchers published a blog post highlighting a paper detailing work on fully 3D printable electronics — namely a simple, semiconductor-free logic gate. The original paper was ...
