Hi. My name is Rob Thompson and I have about 5 or 6 regular sized Numitrons and 2 or 3 small sized Numitrons. The small ones actually plug into an old circular I.C. socket. Anyway I'm hoping perhaps you will release the code and controller used. I'm not good at writing code but I could design a PCB no doubt. I'd love to build a Numitron clock. I have an old David Forbes Nixie clock (ZM1040 tubes) that I love but would love a Numitron one also. My two cents worth. Love the photos. Beautiful work btw. Rob Thompson
