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 ...

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 ...

This intelligent electronic lock circuit is built using transistors only. To open this electronic lock, one has to press tactile switches S1 through S4 sequentially. For deception you may annotate ...

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 ...

Yesterday morning I ran across what sounded like an interesting story from Hewlett-Packard’s labs that seemed to involve a possible transistor replacement, nanotechnology, and the indefinite ...

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 ...
