This is a small project which was done basically out of curiosity. I didn't have enough 74141 Nixie driver ICs in the lab to rebuild a vintage piece of metrology equipment, which is why I decided to just try and create a simple component that can mimic the features of the 74141 and 7441A out of modern SMD components, with the goal to have a pin compatible drop in replacement.
Born as the solution to a problem I had with my isolation transformer kicking out the mains fuse every time I switched it on I build this simple inrush current limiter.
My main goal was to keep it as secure as possible, trying to prevent failures of the relais from causing fires.
You want to know something more detailed about me and my carreer? Just take a look at my CV.
To give you the possibility to learn about me and my skills and abilities I created this reference section to show off some of the things I have done.
