In a recent video [QWZ Labs] demonstrates an interesting technique to use 3D printing to make creating custom PCBs rather straightforward even if all you have is a 3D printer and a roll of copper tape. The PCB itself is designed as usual in KiCad or equivalent EDA program, after which it is exported as […]
Compared to the old 8-bit Arduinos, it’s incredible how cheap modern microcontrollers like the ESP32 have become. But there are even cheaper options out there if you don’t need that kind of horsepower, and are willing to do a little work yourself, as [atomic14] demonstrates. The CH32V003 is a dirt cheap microcontroller—which can reportedly be […]
Hackaday readers are likely the kind of folks that have a favorite keyboard, so you can probably imagine how devastating it would be to find out that the board you’ve sworn by for years is going out of production. Even worse, the board has some internal gremlins that show up after a few years of […]
Vacuum fluorescent displays (VFDs) are one of those beautiful pieces of bygone technology that you just don’t see much of anymore. At one time they were a mainstay of consumer electronics, but today they’ve largely been replaced with cheaper and more energy efficient displays such as LEDs and LCDs. While they might be objectively better […]
