Here’s a really fascinating circuit that implements a combination lock using relays and logic gates. Even with the schematic and written explanation of how it works we’re still left som… ...

From there, with some size reductions, a Master-Slave J-K Flip Flop, similarly using NAND gates and inverters, can be built. The current state of the project is a working sequencer and counter.

Researchers have reverse-engineered a cellular signal processing system and used it like a logic gate -- a simple computer -- to better understand what causes specific cells to migrate.

Hence, in this study, these researchers demonstrated fundamental logic gates (NAND and NOR) using -shaped spin wave waveguides composed of YIG. This element has three inputs and one output. This also ...

A research team from the University of Bayreuth and the University of Melbourne have successfully used optical logic gates to read, write, and erase binary information, marking one of the first ...
