| Four band audio bargraph display, using IN-13 Nixie linear bars. |

A couple of years ago, I stumbled upon an IN-9 Nixie linear display datasheet in Russian. Some members, 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. This IC provides seven bandpass outputs, but since I only had four Nixies, I combined them into low, mid-low, mid-high and high bands. 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. |
