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

5 Stages of understanding transistors
The transistor will go down as one of the most consequential inventions in history, behind agriculture, paper, and the Super Soaker. But on the list of inventions that have completely transformed the very fabric of the human condition, it showed up pretty late in the game, and that's because it's a fairly complex thing. Conceptually … Continue reading 5 Stages of understanding transistors
WTF is parasitic capacitance?
I've always enjoyed the term "hand-wavey". It's such a stark contrast to what people imagine engineers do. You learn all this advanced calculus and linear algebra in college, and get a giant transfer function for your circuit and do the Laplace transform and draw a graph and there's all this talk of poles and phase … Continue reading WTF is parasitic capacitance?
