Over the recent weeks here at Hackaday, we’ve been taking a look at the humble transistor. In a series whose impetus came from a friend musing upon his students arriving with highly developed ...

[Kevin Darrah] wanted to make a simple 3.3V regulator without using an integrated circuit. He wound up using two common NPN transistors and 4 1K resistors. The circuit isn’t going to beat out a cheap ...

Microprocessors in smartphones, computers, and data centers process information by manipulating electrons through solid semiconductors, but our brains have a different system. They rely on the ...

What many engineers once saw as a flaw in organic electronics could actually make these devices more stable and reliable, ...

For decades, chipmakers have squeezed more computing power out of silicon by shrinking transistors, but that strategy is ...

US-based semiconductor manufacturer Diodes has added new automotive-grade bipolar transistor series, DXTN/P 78Q and DXTN/P 80Q, to its portfolio. The components are intended for use in vehicles with ...

In Parts 1, 2, and 3 we took a closer look at calculating “ac” gain and how to desensitize the circuit to temperature and transistor parameter variations. In part 4 we consider the effects of a ...

The idea of using a super-regenerative radio to receive commercial FM stations can be found at various locations on the Internet. Because the circuit is so small, it might be impressive to lab ...
