I've been working a big B-7971 array and numitron clock. I'm a computer scientist but the EE stuff isn't first nature quite yet... Here's a couple videos of my recent experiments:
https://youtu.be/LzOKLMmQZDM https://youtu.be/TbwpUXnU_Eg I found a place that sells aluminum bar stock that would make a nice base for the B-7971 array. It's 3/8" x 4" x 36". I've been looking to tap the aluminum with M2.5 threads for the standoffs. I've got screws for the top of standoffs on the PCB now but would like to find some nicer hex screws. Originally I thought maybe someone made base material with a grid of female threads in it but haven't found anything like that... It's how I started learning the tool and die.
