The small-circuit project illustrates a switch mode power supply (SMPS) that boosts low voltage to the high voltage require to drive nixie tubes while being operated on batteries or low voltage ...

[Limpkin] has an idea for a project that uses a lot of IN-9 Nixie tubes. Where a Nixie tube clock would only use four or six tubes, [Limpkin] is looking at fifty IN-9 bar graph Nixie tubes. These ...

[Tony] built a high-efficiency power supply for Nixie tube projects. But that’s not what this post is about, really. As you read through [Tony]’s extremely detailed post on Hackaday.io, you’ll be ...
