Love that positive metallic click when you put it back together. 😀

Since you can illuminate more than one at a time, you could make a 7+ segment display

Those bulbs are the same as the ones used in old pinball machines: 6.3 V - 250 mA or 150 mA. You can easily find repacement bulbs or even replacement LED's, if needed. Thanks for your good work, Fran ! Thumbs up !

Watching this I had a sudden memory hit me of a children's toy that I must have had as a young kid that did this. I can't put my finger on it.

Should I adjust my television set, or is your T-shirt in control of the vertical and the horizontal ? Congrats' on getting 3.0 up and running 📡

I love the aesthetic of these displays, so simple as well.

Love watching you mess with old displays. Though you shirt today was making my eyes go fuzzy…

This type of display reminds me of a trick they did in "2001 a Space Odyssey" (and also done in other movies) where there is a backlit display with a diffuser. In 2001, those were the displays that said "NAV" and "COM" and such and displayed data or moving figures of an outline of the docking entrance to the space station or whatever. In some scenes, you see this data and images projected onto the face of astronaut. Of course, the light from the display is diffused and would not look like that. Just like the screen you are now looking at is not acting as a focused projector and my words can't be read off your face. Obviously, they merely removed the diffuser for those shots. And perhaps also changed the focus or position of whatever was doing the projecting.

thats a really cool display. I can totally picture them being in some cold war era jet bomber. I would love to make a "control panel" that does absoletly nothing but has all kinds of cool vintage LEDs and displays to mess around with.

That shirt trips me out so much

The DigiKey pen reminds me of a presentation pointer I once found. It used an incandescent bulb and ran off common batteries (I forget the size.) The filament was in a V shape and this got projected by a lens to be the illuminated arrow on the screen. It had some mechanism that let you rotate the bulb without breaking contact so you could put the arrow in whatever direction you wanted.

Wow, you could cause the nuclear reactor to go critical and explode or accidently launch your Intercontinental Ballistic Missile if the repair-guy replaced the lamp bank upside down! I am rather surprised that they didn't design it with some kind of key-way to prevent accidental mis-assembly! Great content as usual, Fran. Thanks for the videos! Maybe someone from IEE will invite you to their factory. Maybe they have a museum?

I like to puff myself up and think I'm into FranLab because Apollo, but, actually, the different vintage display devices are my most "must watch" episodes. The Bina View is still my favorite, followed by the NEMA tube(?).

I love seeing that calculator. I use the same one almost daily.

I so enjoy how you Light Up the tube with retro displays. Their technology is amazing, and you immortalize them in a next generation, digital format. Much Thanks

Your shirt makes me feel like I'm hungover.

Very cool. The type of display HAL would use.

When flashing the "FAIL" on and off a couple of times, I figured some good text might be "COMPUTER MALFUNCTION" and "LIFE FUNCTIONS TERMINATED".

That is a really neat display unit! Thanks for the video Fran!

Thanks, Miss Blanche. 😍

Cool display.

Welcome back! Still KZfaq’s best outtro music 👍

@10:55 I did not expect that! You didn't either. Those look like typical bayonet base bulbs from a 1960's era car dashboard.

I sub to a lot of, “will it run,” channels, you are the original, “will it work,” channel.

Haven’t watched the move but congrats on getting settled and putting out another gold quality Fran lab classic vid!!

Great to see you in the lab again

My wonderful krush giggles like Marge in late Era Simpsons. Love the excitement about swag. I love free stuff you gota see my dumpster surfing "swag"

beautiful display!

" Hey Ernie, you wanna' buy an 8 ? "

Oh yeah, very long ago I worked on a CDC 160-A computer-- it was like the first minicomputer-- 12-bit words, 4K, 12usec instruction time., and a passel of those displays showing the accumulator and the program counter, plus one lone display that showed the CPU status. It read out STOP, RUN, INDIRECT, and I/O. If it showed I/O it meant it was waiting for an iO instruction to complete, so it usually meant it was waiting for a keypress on the IBM typewriter. It had a couple of design foibles-- (1) No subroutine call instruction! Added in the -A model. (2) All IO instructions halted the CPU until IO completion, so you couldn't check for keyboard ready and continue on. and oh, no unconditional jump instructions! So you either had to know the zero or negative value in the AC and jump accordingly, or you had to clear the AC before doing a jump on zero. Good points: very compact, built into the back of a steel desk; all jumps were relative so code was relocatable. But not many sold at $110,000 in 1961 dollars. Anyway, neat displays.

3.0 looking great

Man, those were the days, huh? You could cook an egg on top of that thing. Neat.

These are truly cute !

I seen something like this on an elevator once in Danbury Connecticut

Charming thing. Very random images, but since it was a demo, I guess that makes sense. Good ol' oxidation, yup.

Good to know what these things are so if we ever see them for sale wherever we know to grab them :D

Hi Fran - they look like GE44 pinball bulbs, well - same as used in pinball tables.

I 've got two of these projection displays although with numbers 0 to 9 (and 10 and 11...) , I modified one with RGB LED's and made a single digit clock out of it. It uses different colors for displaying the different time digits and does a 10 second countdown before displaying the next minute :-)

SO glad to see you back at it, Fran! hip, hip, hooray!

Everyone here already knows Digi-Key is one of the best suppliers. Many of my supplies came from them when I worked for iRobot.

Glad to see you back in business, Fran. This unit looks like something they might have used in an old nuke plant (or a movie about one).

I suspect that these were used in some kinds of test electronic test equipment, perhaps also military or medical equipment.

What are you complaining about? DigiKey just sent you a great bit of film chip for your nightlight.

thanks fran :)

I was curious about what the red and gree ones would had looked together, but then given some thought it would be too low-contrast to flash other things on with the warm white bulbs.

Very cool. Love the colour and word combinations. I wonder if you could make a modern version of this using "off the shelf" parts like those 5050 LED lenses you can buy off eBay and 3D print the enclosure to hold the lights and lenses in the correct alignment and focal distance, then use a laser printer with overhead film to print the mask films. Obviously you can just use regular coloured gel film for the coloured ones, but perhaps a colour laser printer could make some interesting masks. On a slightly tangential note, I don't know why it stuck in my head, but ages ago I watched a video where the dude was working on some electronics thing and he got the parts from "diiiiigiii-keeeeyyyy", which he said in the long, drawn out 90s stoner voice that he used in the video. So now whenever someone says digi-key, that's the voice I hear in my head.

"Pass fail!" with a red and green light please :) These bulbs look like Ba9S bayonet to me.

You get the neatest toys! I probably saw that display at the IEE booth at the NYC "Electro" electronics trade show (back in the 80s). I'm surprised the lamp block is not keyed to assure proper orientation. As to uneven lighting, you probably know better than anyone how the filaments are RARELY aligned, so replace the bulbs or swap some around? I'm surprised you didn't use a little flashlight or bare LED when the back was open to check all 12 lenses.

Hi, Fran!! So glad you are getting settled, again. ;-) You Rock and you ARE a Rock! Thank You.

cool ideas...I want to know if I can connect broadcast monitors to modern computers to use with time code or regular black and white displays, for older music software..

Used to have to replace lamps like those. 1829, 1819, always caused grounds which caused bigger problems.

So nice to see you back Fran

You should hook it up to a rotary switch, it seems like the perfect way to select the projection.

Fran you show us the neat little things, like this display unit!

Nice, not sure what I'd ever use it for though..

Fascinating and informative as usual. Thank you Fran.

Speaking of swag, the best I have is a DigiKey ruler they sent me for some reason. Mouser not so much :)

Reminds me of my old Ghostbusters ghost zapper

Interesting displays makes me wonder exactly what it was intended for.

I wonder if IEE had some extractor tool that solved the 3-handed problem. It's obviously not an insurmountable problem, but if they were showing this at a trade show, they'd want to illustrate how quick changes could be. 🤷‍♂️👍️

Funny that faint P in Pass. 😂

Fran, I wish I knew about you 12-13 years ago or so. I had picked up a bunch of new letter things like you use in your intro from government surplus. I had no idea what to do with them so I tossed them. I thought they were so obsolete nobody would want them.

I believe this may be the display that is used in the opening scenes of Lucas' THX-1138. The font of the numbers seems correct.

You might has said it but I missed it, how about changing the bulbs for LED's? :)

Thank you for the video. Very interesting and....fun.

💡 What if you somehow place the "projection sheet" from that pen into that old display? 🤔

Focus you feck!! 🤣 couldn't help myself. That display NEEDS to be used in some kind of Franlab build. Thanks for showing it to all of us😁

I feel you have enough bits and pieces to make an impressive villains lair.

I used to design and build wafer processing machinery for Jurgen Staudt..........somewhere in this crazy world that used to mean something. Today that fact is nothing more than another layer of glaze over the eyes.....lol

Same display as the vanishing elevator floor indicator

It's the Andromeda Strain all over! NOoo!!! ;-)

Nice display, some fun potential there. And yay, Lab 3.0 is go.

Whatcha gonna do with that 7471?🤔

How’s your flying training going?

Lovely stuff Fran. Would you ever consider creating your own custom masks / gels etc for these displays?

Your vid seems sharper/clearer - new camera?

Thanks for sharing. 😉👌🏻

It looks like with IEE failure WAS an option 😜

Why does this display remind me of classic Dr. Who?

Ok, so "series 10" is not the "MIMO"

@12:46 who's your friend

I was thinking that this video was going to be about the inventing process FAIL, wrong, not this time, negative, nope, oh no,...

Your shirt made me dizzy my eyes kept on trying to focus lol btw do you own every technology ever invented 😁 love your channel

Why is it that everything made now looks so very 'born yesterday' compared with this stuff. I'm talking about the unevenness and over all cheapness is worse looking than it should be when using the materials they do today. I mean it's almost like business insists on the born yesterday look as though they like it. Why!? I've been wondering for over 20 years! But the last 10 years in particular.

Pass! Pass! Pass! Yay!

Failure. The noun.
