For the Lamina B.L.A.C.K I wanted to use orange colored nixie tubes, like the ZM1210. I ordered some glass lacquer for light bulbs in orange and red colors than I mixed them until I had a desired color and dipped them to paint. For each B.L.A.C.K clock I need 6 nixies, plus I send 2 spare
Just received a bunch of IN-9 nixie bar-graph tubes. Something cool and new is coming hopefully. I have some design ready, let see what comes out of it.
