I am fairly sure he is still very active and have certainly heard from him in the last month or so, have you tried emailing him? Contact details are at: https://www.nixieclock.biz/Contact.html
I am very interested in your IN-13 based project - I have been wanting to build a spectrum analyser for several years, I have experimented with drive circuitry and made the things glow but go no further than that. I did plan to use a big Teensy micro with lots of i/o, one port to drive each tube on a 20 tube system but I suspect that there are more elegant methods. Please do keep us posted on your plans. - Richard On Wednesday, 4 March 2026 at 14:18:02 UTC Christopher Jackson wrote: > Hi everyone, > > Sorry for my intrusion. > > I will have more in a month or so a new design I am working on using Bar > Graph IN-13 Nixie Tubes, Arduino based although the languages used are > unimportant since I design in a few dozen different Assembly languages. > > It is a 33 tube architecture which can act as a weather station using > weather related sensors to give the user a moving window of 33 > seconds/minutes/hours/days/(years?).
