Could a single memristor replace both the driving transistor and storage capacitor in micro-LEDs? Prof. Tae-Geun Kim and team ...

One of the joys of writing up the entries for the 2025 Component Abuse Challenge has come in finding all the different alternative uses for the humble transistor. This building block of all modern ...

For our 2025 Component Abuse Challenge there have been a set of entries which merely use a component for a purpose it wasn’t quite intended, and another which push misuse of a part into ...

It ‘s worth noting that back EMF plays a critical role as a natural current limiter during normal motor operation. When motor ...
