I love it when Sam says "and I've got another project..."
Those tubes are truly magnificent
You could make a museum of just VFDs and LCDs and I'd still want to be there. I've been into those since the 90s, and am still using the very first one I ever got.
Putting valves/tubes into a synth for data/visual relay needs to be a project. A scrolling display would be the ultimate but I suspect the cost would be the ultimate pocket kicker too. 😂
The mystery device looks like a motor controller. It has armature connections (the spinny bit) and field winding connections (the outside magnet bit) and also has the firing angle for control of something like thyristors or IGBTs. The additional isolated gates switches also suggest this.
I love the color they make
That last device immediately put me in mind of ORAC (from Blakes 7)!
I'm guessing "firing angle" will be for thyristor control. Maybe a thyristor based 3phase rectifier?
I'm in the process of restoring an Elektronika-7 I bought years ago, along with a set of replacement tubes, and finally a few weeks ago pulled out of the attic to get to work on it... only to find that I'm short about 5 tubes, and due to recent world events, they're all the sudden not available anymore... Might have to mix in a few worn tubes with the new replacement ones.
Good old IV26 tubes, I bought a load of them years ago for a homebrew version of that Elektronika clock but never got around to doing anything with them - one day perhaps.
I like this place, Good Show.
Damnnnn, I need to use these for my sequencer step displays now!! 😲🤔🤯
My guess is the mystery box has something to do with motor / generator control. Looks like there's a 3-phase section. Firing angle is probably some kind of trigger with respect to the AC phase angle. I doubt it has anything to do with rockets or ballistics. The common terms are just a coincidence. Maybe it was from a university department - hence the transparent box - so you would see what was inside.
I have a bunch of vintage Japanese VFD tubes, Iseden itron DG12Cs, which I got when Fair Radio was selling broken driver boards with 12 of 'em on for $5 each. They're similar to seven-segment displays, but actually have nine segments - the middle bar is broken in half, and there are extra internal vertical bars. If you imagine the 8 with a + overlaid on it, you're pretty close. Each digit also has a trailing decimal and a leading apostrophe, for 11 total elements.
IV-26 Type 1 - are universal, they have all dots as separate wires and it will work in big and small Elektronika 7 clocks, IV-26 Type 2 is designated for the big clock only and IV-26 Type 3 is for the small one.
Superb Sam. The Museum is looking very well stocked with interesting gear.
IV-4/17 18 segment VFDs are lots of fun...
Great update Sam!
That box is ORAC from Blake's 7.
The odd thing looks like a 3 phase motor tester / controller / experiment driver , transparent case would indicate an educational tool or set up for display
