Hello all - First answer, I did the artwork in various graphics apps, then printed out the negative on clear inkjet transparency film. I used the photoresist film on a sheet of brass, then conventionally etched in ferric chloride. After etch, did an aged effect with mini-torch and added patina with a salt-water dip. Light burnishing on 1000-grit silicon carbide sandpaper to bring the highlights out, clear acrylic overspray for protection.

Second answer - what kind of detail do you want? The circuit done in KiCAD, boards by JLCPCB, and I cut the cabinet panels with my dinky 6-watt laser engraver system. Display readouts are in-12 or in-16 Numitrons from Russia. Clock circuit is all discrete 4000-series CMOS logic, no arduino or uController.

That's beautiful. How did you make the name plate? 

Just a photo???????  Come on guys, a little detail please!
