There was a time when all that was available to the electronics hobbyist were passive components and vacuum tubes. Then along comes the integrated circuit, and it changed everything. Fast forward a bit, and affordable programmable microcontrollers arrived on the scene. Getting started in electronics became far easier, and the line between hardware and software started to blur. Much more recently, the hobbyist community was introduced to field programmable gate arrays (FPGAs) and the tools necessary to work with them. While not as widely applicable as the IC or MCU, the proliferation of FPGAs among hardware hackers once again opened doors that were previously locked tight.
We’re currently on the edge of another paradigm shift, but it’s no surprise if you haven’t heard of it. After all, the last couple of years have been a bit unusual, so the 2020 announcement that Google was teaming up with SkyWater and Efabless to enable the design and manufacture of open source application-specific integrated circuits (ASICs) flew under the radar for many people. But not Matt Venn, the host of this week’s Hack Chat. For him, it was the opportunity he’d been waiting for.
Matt started like many of us, building electronic kits and building new gadgets out of old discarded hardware. He graduated to microcontrollers, and became particularly interested in FPGAs when the open source toolchains started hitting the scene. Of course by this point, it was much more than just a hobby for him. He was presenting a talk at the 2019 Week of Open Source Hardware in Switzerland when he saw Tim Edwards from Efabless demo a chip that had b ..
