Nixie tubes (also known as digital display tubes) are a very common thing, but the most common ones we have always seen are red. Actually, I think it's quite ugly. Therefore, for so many years, I have wanted to find an RGB digital tube, so that it will be more beautiful. But after searching everywhere, there are red, green, blue, and white ones, but there is no RGB color. There is no such thing in a certain treasure. Since there is no such thing, then I will make one myself. So today I I am going to make a cheap and cool RGB digital tube.
