A couple of years ago, I stumbled upon an IN-9 Nixie linear display datasheet in Russian.
Some fellow members (Prairedog and Altaero) in this forum, helped me translate it and my curiosity was piqued.
I was able to obtain some IN-13 tubes on Ebay (they are longer and more linear) and after making some static displays, decided that it would be best if I made an audio VU display.
Almost simultaneously, I found the MSGEQ7 Seven Band Graphic Equalizer IC, and decided that it would be a better project.
I finally completed the project as shown in the video: https://youtu.be/5oLu2AATviQ
The core is a solid block from a Mesquite root, which is hard enough to be machined and provides a very unique and handsome look.
The video does not do proper justice how gorgeous this project actually looks in person.
