I see so many misconceptions about BJTs, people seem to either over-complicate the hell out of them, or over-simplify and then wonder why things don't work. I want to find a nice middle point, something overcomplicated that doesn't work. Today's post is to build a simple ground-up understanding of the BJT using fun analogies that … Continue reading WTF is a BJT?

ABCs of PCBs
Printed Circuit Boards (PCBs) are the backbone of electronics, the land we build on. To the average person, when you're thinking of circuits, you're thinking of PCBs. The first PCB I professionally designed (well, modified) There's a lot to say about circuit design, layout, signal integrity, safety, manufacturability etc. but I wanna get even more … Continue reading ABCs of PCBs
Misconceptions: small-signal analysis
One of the, if not the biggest hurdles to understanding transistor circuits -- and system modeling -- is small-signal analysis. As with all things, the reason it's difficult to understand is that professors are given very little time to provide context, so it's given or received like scripture on golden tablets in a language you've … Continue reading Misconceptions: small-signal analysis
“So like…what even IS a resistor?”
A friend of mine who had taken a circuits class asked me this and at first I was confused. He took a whole circuits class, half of it was spent on resistors. And then I realized it's honestly a really good question. They're presented as a scribble on a chalkboard with no context, you do … Continue reading “So like…what even IS a resistor?”
