Showing effects on the Masska nixie display
Finished the "masska" display! This is for a client who wanted to show his company name on nixie tubes. After ruling out B-7971 tubes as they are too expensive and rare, knowing there were some nixie tubes with letters instead of numbers, I looked at the datasheets of the IN-19's and IN-15's and found that I could create the word with a combination of IN-15A and IN-15B tubes.
Instead of going down the easy path by just wiring up the relevant cathode letter for each tube and turn on, we decided to use a custom clock chip programmed to just display a single "time" all the time and every minute display an animation to exercise the other letters in the tubes. Dave at unusualelectronics did a great job of the custom chip and I was able to use the same PCB I would use for a 6 digit nixie clock.
The client did not want an old multimeter as the case, as I usually do for nixie clocks, just a basic wooden case. I was inspired by a laser cut case I saw on the internet, so I designed this base on the look of that. The tricky part was how to get all the case pieces to stay together without using screws. I created ridges on the two panels that would hold the tube sockets and the front panel and then cut out notches in the lid and base to line up with the ridges. This would hold them in place with a combination of PVA glue and hot glue. A couple of magnets in the lid and case hold to top down.
I am really happy with how this turned out, Dave did a fantastic job on the programming and with a stain and oil on the case, it has come up alright as well. This has turned out to be an international project! Nixie tubes are bought from Russia (manufactured in Ukraine), chips programmed and circuitry designed in the UK, case made in New Zealand and all assembled in Australia!
