More “nixie tube” fun, this one a really gorgeous tube clock in a CNC-milled wooden enclosure. The builder has the schematics, layout, BOM (Bill of Materials), firmware, etc. on the site, and is also is making clocks for sale, for US$1,500 each. He says it’s about $190-200 in parts. Not the easiest build, with a lot of surface-mount components, but if you’re up for a challenge… Cool clock!
