Waveguides come to mind, but so do active elements like filters made from nothing but PCB traces, which is the subject of this interesting video by [FesZ]. Of course, it’s not quite that simple. A PCB is more […]
Join us on Wednesday, September 25 at noon Pacific for the High-Speed PCB Design Hack Chat with Bil Herd! Printed circuits have become so commoditized that we seldom think much about design details. EDA software makes it easy to forget about the subtleties and nuances that make themselves painfully obvious once your design comes back […]

Unfortunately for [Jeremy Ruhland], it turns out that FR4 is not great light pipe material, at least in one dimension. The backstory on this has to do with #badgelife, where it has become popular to reverse mount SMD […]
