You can define the word crazy in myriad ways. Some would say using SMD resistors and QFN microcontrollers as structural elements is crazy. Some would say hand soldering QFN is crazy, much less trying to do it on edge rather than in the orientation the footprint is designed for. And of course doing it live […]
If you want to build hundreds of a thing (and let’s face it, you do) now is a magical time to do it. Scale manufacturing has never been more accessible to the hardware hacker, but that doesn’t mean it’s turn-key with no question marks along the way. The path is there, but it’s not well marked […]
Jeremy Hong knows a secret or two about things you shouldn’t do with radio frequency (RF), but he’s not sharing. That seems an odd foundation upon which to build one’s 2018 Hackaday Superconference talk, but it’s for good reason. Jeremy knows how to do things like build GPS and radar jammers, which are federal crimes. […]
Ground is an interesting topic when it comes to engineering. Either it’s the reference level for a digital circuit (not necessarily at zero volts, either), or it’s the return path for current, or it’s the metal chassis, which shouldn’t be the return path for current or else something’s terribly broken. Erika Earl’s talk at this year’s […]
