If you’ve spent any time on hackaday.io, you may have noticed that more than a few denizens of the site are fans of “alternative” electronic logic. Aiming to create digital circuits from such things ...

Figure 1a shows a latching circuit based on an optocoupler, IC 1. If the off switch remains closed, pressing the on switch powers the LED in the optocoupler. Thus, the transistor in IC 1 turns on. You ...

The often-quoted Moore 's Law says that we can expect processors to double in capacity every 18 months. And that has held true. Now computer scientists warn that - without some significant ...

With a recent breakthrough in making circuits with molecules, Hewlett-Packard hopes to change chip history and expand its own role in the process. Researchers from the Palo Alto, Calif.-based ...

US scientists have made nano-scale devices they claim could one day replace current transistor technology. The tiny devices, "crossbar latches", are made up of a combination of crossed-over platinum ...
