The most fascinating project you can build is something with a bunch of blinky hypnotic LEDs, and the easiest way to build this is with a bunch of individually addressable RGB LEDs. [Ole] has a great ...

The matrix binds the fiber reinforcement, transfers loads between fibers, gives the composite component its net shape and determines its surface quality. A composite matrix may be a polymer, ceramic, ...

A switching matrix used in a test system connects a signal on a particular column to an instrument on a certain row. Typically, there are more signals than instruments, so several voltage measurements ...

Computer scientists are a demanding bunch. For them, it’s not enough to get the right answer to a problem — the goal, almost always, is to get the answer as efficiently as possible. Take the act of ...

Fingerprint matrices transform scattered light into clear images, overcoming challenges in opaque environments and paving the ...
