Wouldn’t it be nice if VFDs made a resurgence? Just put VFDs on everything, already! Make VFDs the new “blockchain” or “neural networks” or whatever. Priorities, people!
For those of you who enjoy links, I have great news! I found some!

can you make a video on all the other little custom displays of various technologies?
VFD is the technology behind Nutube, used by Vox, Ibanez & others for guitar & amp gear in some newer products. VFD can do the same thing as a 12AX7, but with lower current.
It's a TN type negative LCD. You can tell trivially that it's TN type because of the poor viewing angle. TN displays like this were very cheap.
5:31 totally agree. They are always the wrong colors
I am going to go with early 90's on that JVC based on the button styles, coloring, and controls. 1990-1994 likely. ALL the stereos looked like that because Poineer came out with the phenomenal VSX-D702S receiver…. which everyone copied – I have one in my stereo rack to the right of me right now, use it every day!
GM made similar negative lcd dashboards in the 80s, something like that https://www.youtube.com/watch?v=EEGZaqly5jc . Also halogen lamp backlit
@0:25, What timeline are we in? Is this the Alpha or Beta line?
0:11 WRONG they do it with OLED these days.
3:30 hoiup
I was about to say "maybe this is during a time before manufacturers were slapping buzzwords on products to sell them" then I noticed "ROLLED RECEIVER" and "Quartz Lock" prominently displayed above the display panel.
at 3:44 that is my favorite radio station: WUNC
7:05 I saw a Rick Roll coming there.
JVC ran this line for a while. Not long after retiring their stackers, they kind of wound down their presence in the home electronics market. The amplifier was a good find. That was a well-sold model.
Fisher FM-26. It was a tuner that complemented the Fisher CA-26 integrated amplifier, back when "component style" sound systems were popular. (Actually, the FM-26 needs the CA-26, as it doesn't have its own power supply and plugs in to a proprietary DC power output socket on the CA-26.) Getting back on point, the Fisher FM-26 has an LCD with a warm yellow backlight, and a tiny red filter over one of its display elements to make it appear to "glow red" when it becomes non-opaque.
I have a feeling this style of reverse-contrast LCD + backlight was introduced when custom LCDs started becoming cheaper than custom VFDs, but the aesthetics of VFDs were still in-vogue.
I gotta say, man, watching your videos while inebriated is rather entertaining. It's entertaining when sober too. Okay, your videos are just entertaining in general.
TIL that vfd exists.
1:10 should be a 1990-1994 Lincoln Town Car instrument panel
For those who are curious.
Variable frequency drive. VFD that’s what I thought at first.
4:28 – I recommend investing in a simple diffraction spectroscope. It's fascinating to see the different spectra of different light sources and the absorption or reflection of various materials, plus it can help you figure out what kind of light you're looking at. I can see local street lights that are fluorescent. I can see that the little red lights that tell me my stovetop surface is hot are neon. I can see how a typical color LED has an emission spectrum with a smooth peak, while a laser LED has a single, pronounced spike. I got a basic one for about $30, and it's so clear that I can even see absorption lines from Earth's atmosphere. With a little bit of familiarity, you'll be able to tell whether you're looking at a filtered incandescent light, a mixture of red and green LEDs, or a true amber LED.
Your amber looks brown to me
Phosphors are incredible. They catalyze the vaporization of the tinest packets of condensed phase spacetime, converting them back into plane waves for us to see with our eyes.
Psh JVC! Lamoid! Oh… Pioneer… well I suppose that is okay. Lol
Get a cotton swab and some alcohol, and clean that JVC. It may be old, but it can still be spotless.
All I know VFDs as is "Variable Freqeuency Drive" and I was very confused. I was like "we've never used more of them and they're seriously amazing."
From the title, I was expecting a video on variable frequency drives…
Took me until about 5:40 to get the Lemony Snicket reference… lol
Don't complain too much, the equipment is 32 years old and still works.
You got bamboozled.
False, V.F.D. stands for "Very Fun Dragon"
I think your microwave just has an LED display.
Kind of disappointed this was not about Variable Frequency Drives 🙁
"Am I off my rocker? Well as it turns out my rockers is on the corner so I am indeed off of it!" 😂 🤣😂 🤣
Check out the display on the JVC RX-709… when I had one in the mid 90s it's display was the coolest thing I'd ever seen on a receiver.
And here I thought you were about to discuss motor controls 😜
My short-attention-span brain rather likes this shorter format of Technology Connections.
Those VFDs are so beautiful. Reminds me of my parents' old sterio setup.
Dot matrix VFTs look so cheap and ugly to me
Somebody better notify the Volunteer Fire Department about this.
The best thing about the VFD colour scheme is that it is reasonably friendly to dark adapted eyes. The bright blue LEDs that were all the rage when blue diods could be made cheeply are _horrible_. Sure, even red LEDs can be too bright, but they rarely illuminate a whole room.
I almost expected to get rickrolled at the end
My parents used to have this radio which had a huge VFD, displayed time, titel and songwriter. Which disk was playing and have 5 or 6 bands for the spectrum analyzer. Sadly we discarded it, but i want it again (if even possible) i dont know the name, or the brand anymore sadly. If anyone here knows some which has the same layout please let me know 🙂
why not just search "vfd mimic backlit lcd"?
That "HA" sound effect killed me :')
1:43 – this sounds like most 13 year old boys when a girl is in the room.
If you tried to use these to build something, it's more expensive than a color LCD or even color OLED panel.
