He subjected his initial design to a lot of careful experimentation to verify that he had met his design goals, and then embarked on a little tweaking mission in KiCad to trim the PCB’s footprint down by 27%. The three separate blog posts are well worth a read by anyone interested in learning about electronics design. But paid special care to minimize the EMI output of the boost converter through careful design, and he managed to pack everything into a compact 14-cm² PCB. The overall goal is simple: 5 volts in, 170 volts out at 20 mA. But most Nixie power supplies seem to want 9 volts or more on the input side, which can make integrating them into the typical USB-powered microcontroller project difficult.įixing that problem is the idea behind ’s 5-volt Nixie power supply. Their enduring appeal is due in no small part to the fact that they’re hardly plug-and-play generating the high-voltage needed to drive the retro displays is part of their charm. Love them or hate them, Nixies are here to stay. Vintage aircraft instrument becomes an USB peripheral. Teardown returns to Portland in June 2023.
