Hi ! I want to build a blockclock for myself, with this type of tubes: https://en.wikipedia.org/wiki/Nixie_tube but I don't have a lot of knowledge to how actually doing it. All I want is to count the mined blocks. Nothing else. Can someone point me a source of information, or link to the parts that I need to get in order to build it ? Every piece of information is welcome ! Thank you !!!
