"show cat" yea, sure, I haven't posted this thing in a while. I still love it to bits and will be very sad if it develops serious problems.

Though I also wish its creator a long, healthy, and safe life free of Russian aggression, and not just so they can help me replace it/parts!

The museum has very graciously received a #Philips PM6620 counter, one of the very few Philips instruments to use #nixie tubes.

As well as a #HP 182T display with 8558B spectrum analyzer and a HP5304A counter.

Should you have user, service manuals or schematics for any of these they'd be greatly appreciated! Especially the PM6620 seems very difficult to find.

The HP8558B needs repairs specifically its RBW does not work very well, if you know common faults / repairs let me know.

And finally, assuming that other piece hasn't been published in the last few minutes, a look at a neat project which reads out a motorbike's selected gear from the OBD port.

...except the OBD doesn't report that. So it gets *clever*. Oh, and it displays it on a vintage #Nixie tube, because why not?

Bummer. Got a bunch of these nixies and about half have some missing digits that do this. Trying to scrounge enough to send some to a fellow Tektronix nerd in Germany.
Some of them have digits that just do this and don’t fire at all, while some others have one or two digits that won’t fire unless you jump from an adjacent digit with a little bit of overlap where they’re both on.
I know they had a bit of radioactive magic in them to help them fire, which I assume has decayed beyond helpful at this point.

This is a Sepia composition of my Raspberry Pi5 SBC.

Without even having used the GPIO yet, the machine has brought a lot of Joy to me, already.
I'm studying the deluge of projects boards / breakouts available for the GPIO, so that I can choose what I want to do first, after which I will go of course for those beautiful tube driven clocks. Of course I'm referring to the Nixie tubes.

What I want to achieve is literally controlling the high voltage / current tubes through bridging Hardware with my SBC Raspberry Pie5

@tillymoose

Thank you for the response. Now I know for certain that nice projects are possible. I've just seen that the prices can vary between EUR 15 and EUR 50 per tube, depending upon the size, the colour and the type that you choose

Is there anyone here who has worked with these kind of vacuum tubes? Are there projects released for the Raspberry Pi where I can work with this kind of tubes?

I not only love the way they look but it would be nice to be able to make a device which looks like this has exactly the same tubes but is controlled in another manner then just the pure wonderful analog way

Газоразрядное табло для машины времени, или как я оказался в титрах к японской дораме

Уже не первый десяток лет газоразрядные цифровые индикаторы переживают свой ренессанс. Одни собирают часы и метеостанции на широко распространённых ИН-12, другие уходят в тему с головой и пытаются наладить своё производство ламп немыслимых доселе форм и размеров . Большинство конструкций на газоразрядниках, которые мне попадались в категории «для начинающих», использовали давно снятые с производства микросхемы по типу К155ИД1 или SN74141. Также многие встреченные схемы экономили на оных, используя один дешифратор для всех ламп сразу, коммутируя аноды через оптопары. Поставить же две ИН-12, валявшихся в ящике уже десяток лет, хотелось в свой проект CD-плеера — отображать номер трека или радиостанции. Поэтому хотелось иметь такой же модуль, как и любой другой дисплей — не сильно крупнее геометрически, чем сами лампы, подключающийся по какой-нибудь стандартной шине и не требующий от процессора никаких заморочек с обновлением динамической индикации и всего такого, да и на производящихся по сей день компонентах до кучи. Кто же знал, чем это всё для меня обернётся!

Voltage measurements starting to show signs of life after swapping out a few bum transistors in the 0% zone card. The 0% cursor isn’t working yet, so I don’t know where it’s measuring from, but I can get changing readings by moving the 100% cursor. The change roughly corresponds the peak to peak amplitude, which is promising.
