Mr Carlson's Lab, do you think you could do a series for beginners? I’m a current EE student and would like to get to your level in vintage electronics. A series outlining skill building projects would be great. Thanks for all the interesting videos
Was there a follow up video to this if so what was the title
Time to drop everything I am doing! Carlson is in the house!
Had one of your mystery tubes when I was a kid - 70 years ago -- was mounted on a Bakelite chassis in an octal socket along with a vacuum tube of some kind and a relay. Mystery tube had a :"plastic": dome over it and a light tube. Shine a light on the tube, set the sensitivity control just right and the relay would close. Could use it when a parent was sneaking up on me and would break the light beam and a bell would ring warning me to put my comic book down and pretend to be sleeping. Thanks for the memory.
Great story Robert, thanks for sharing that!
J. Millen Co. mini oscilloscope, was made to fit in the place of an S-meter on a communications receiver. Millen was a legend in radio engineering, and designed some of the best equipment for National Radio Co. including the SW-3, SW-5, HRO, and NC-100 series
Best trivia quote ever. "If this is too easy,, they can get a lot harder. I have some very strange devices"
Early flux capacitor prototype. I had one in my Delorean.
No, no, much earlier than that. I had one in my VW Bug (Beetle for non-Americans).
I love, love, love the way you bring ancient electronics back to life, and into modern context. You sure find some interesting pieces! 😁
No idea what that device is but I do know what the best electronics channel is! Just love your output and you always leaving us wanting more!!
Watching your videos makes everyday life a bit more bearable! To me it's my "Bob Ross" moment, listening to your explanations of awesome stuff i've never seen before. Thanks for all those hours of fantastic video material, showing us the joy of electronics!
Raise your hand if you ran around the house with a flashlight shining it at all your flickering power strip lamps! *raises hand*
Only have the one old power-board to test this, but after trying it with a 9-LED torch (way too bright for my eyes to tell how fast it stopped the flicker), I then tried again once I'd left it disconnected for a while with a single-LED torch (about 2 secs to react), then again later with a laser-pointer (which caused the neon to react & steady instantly)!
lol i did :D
You'd think its own light (neon) would be enough to stabilise it!!!
I paused the video to run around the house with a flashlight.
@@mechanicfrank900 Same here 😊 Unfortunately, I could not find a single flickering neon bulb... All perfectly steady 🙁
It’s a transtator, the basic building block for all federation technology.
Millen 1 inch oscilloscope used one in my ham shack 50 yrs ago ,love your website, thanks
You could buy them in the 70s. I have a similar 6" Russian made tube with unsymmetrical plates. Cheap new old stock.
I recently found this channel and have been blown away by the level of information you provide! Seeing how old electronics work has been a great experience!
Glad you're enjoying!
When I worked in radio we had an old old old mixer desk. It had one of those on it, to show the sound (not the typical waves you see today, but stereo, with a center dot, showing sound from the center and out, depending on stereo/loudness/etc).
You’re videos has such great audio Mr. Carlson. Very impressed by the quality of the sound and of course great lighting to really see what you’re working on , thumbs up!
The moment I saw that little tube face sticking out it made me think of my portable Cossor 1039M that I’m currently restoring. And what did you do - pull out a Cossor tube. Made my afternoon that did!
Gotta love 50's electronic test equipment, thanks for sharing Mr. Carlson.
I like the Lambda Model 71 power supply!
Always happy to see a new video from Carlson lab
I used to see ads for this little device in 1950s QST magazine. I believe it was made by Millen. It's a tiny oscilloscope with a one-inch CRT and circuits for focus and brightness. It needs a power-supply and sweep, deflection circuits.
Very cool! I love this channel, because I learn things I didn't even know I didn't know.
Very nice little o'scope. Thanks for sharing, Mr Carlson :-)
Years ago I built one from scratch as part of a homebrew tube-type 40 meter AM/CW transmitter/receiver rig and I connected the horizontal plates to the filament supply to get the horizontal sweep and connected a slug-tuned coil and capacitor tuned-circuit that would resonate in the 40 meter band (7-7.3 mHz) across the vertical plates and the thing worked nicely for adjusting the modulation on AM and monitoring the keying on CW. To couple the 7 meg RF into the coil I wrapped a couple turns of insulated hookup wire around the body of the coil-form in phase with the 7 meg coil and connected one side of that link to ground and the other side was placed nearby the transmitter section's output tank coil.
You are the Carl Sagan of electronic repair, captivating absolutely love your videos please keep them coming
Many moons ago I used the same crt in a homebrew modulation meter, wish I still had it. Circuit came from an RSGB Handbook. Love the LIssajous trace.
How does Mr. Carlson's lab not have a million subscribers yet?
ikr
Your videos are so well done. The best on CZcams.
damn I expected a hologram of princess Lea to appear.. asking Mr Carlson to save her...
Oh, that thing is adorable! Thanks for the video, Mr. Carlson!
Woo hoo! Millen 90901 mini oscilloscope unit! Saw it in the radio amateur's handbook when I was 11. Nerd porn at its finest! I've got one of those now too!! Highly collectible. Hooked mine to a scope clock board. Thought I posted a video?? Guess not. The center of the screen is dim because of sine wave scanning. It is causing a form of velocity modulation.
videolabguy I remember this scope too. I read ARRL Handbook really much as young in the 60’s when received my ham callsign OH2BIO. I still have some older ones on my library. Those were real masterpieces. And heavy too.
Yeah, I used to love looking at the Millen ads in 1950s QST magazines.
I was born in 1940 and my dad was into electronics. He had a 1946 ARRL Handbook that he encouraged me to study as soon as I could read. I remembered all the cool ads in the back pages. Ham radio was banned during the war but ARRL was still active. I think a lot of hams went to shortwave listening. A few experimented with carrier wave(?) communication over the power lines. I had a one tube, regenerative SW, receiver that he built for me and a decent antenna. I used to listen to the hams on the 75 meter phone band. I was puzzled when ssb came along. He bought me a Hallicrafters S-40b in the early '50s. I got my Novice in the '53, General in '56 and 1st Class Commercial in '57.
I wonder if Cossor actually made these as well, as they were the ones who marketed the world's first all-electronic oscilloscope back in 1932.
Wonderful! Looking forward to the project to use that little CRT =D
Must have been fun designing new tubes back then. I do remember a drawing of a similar looking photocell from a Philips book for automatic doors!
Wow, I haven't seen a setup like that since I was a kid in the '60s. I had 2 friends who's fathers had shops like yours, but they were never interested in any of it. They became my foster-fathers due to my own dad shunning me from birth. They were both kind and patient with me and got a kick out of my enthusiasm and I learn a lot. One gave me a military emergency 2-way radio that was the size of 2/3 carton of cigarettes with rabbit-ear collapsible antenna that formed 2 "Ts". I managed to hook it up and when I hit the transmit button the TV went berserk. I called a friend 1/4 mile away and he said his was doing the same. I subbed your channel and look forward to more
Thanks for sharing your story Keith!
You are an awesome teacher and you really know your stuff. Thank You, Mr. Carlson!
Done with work...straight to Mr. C’s lab!
Interesting video, Yes I did learn something from you today. I will look forward to your next video. Thank you.
I do love the mini CRT what a treat. You have come up with some of neatest stuff. Your trivia question device looks like a high power arc lamp. So it will be fun to see what it actually is. Thanks as always. I love the videos...Vic
Cool! Now build the world's tiniest Asteroids game with that little guy!
Photocell tube was the first thought on the mystery gizmo. Great to see a young feller so well versed in the old craft.
When you got that Lissajous pattern on the CRT I was reminded of an old TV show where they control the vertical and they control the horizontal. Aah, flashbacks!
_"There is nothing wrong with your television set. Do not attempt to adjust the picture. We are controlling transmission. If we wish to make it louder, we will bring up the volume. If we wish to make it softer, we will tune it to a whisper. We will control the horizontal. We will control the vertical. We can roll the image, make it flutter. We can change the focus to a soft blur or sharpen it to crystal clarity. For the next hour, sit quietly and we will control all that you see and hear. We repeat: there is nothing wrong with your television set. You are about to participate in a great adventure. You are about to experience the awe and mystery which reaches from the inner mind to - The Outer Limits."_
Even reading that raises goosebumps! As a kid, I had to hide behind a pillow watching that show!
My TV did that "Soft Blur" thing real good...Not so much on the "Chrystal Clarity" bit
The Outer Limits. Watched it as a kid. Great show.
That's just bad-ass. I love the old tube stuff. NO idea what the device is for the trivia. Cheers! Chris - NI7I
this "trivia" was all new for me. again, best thanks!!!!
I learned all of this material in the 50's and 60's. I spent 40 years in the electronics business. I'm retired now and miss it all so much.
Thanks Paul! Cool little CRT! I guessed wrong the last time and would guess wrong on this one.
I like that little device. I think that's nice for display in your curve tracer project. Thanks
You had me guessing! Thanks Carlson for an always interesting vid!
And again a very interesting video. Beautiful old device! Thanks, greetings from the Netherlands 🇳🇱! 🤗🤗🤗
I wouldn't guess without the others' comments :) Interesting trivia question! Thanks a ton! 👍
When I saw it, I knew what it was. Smallest oscilloscope I have ever seen. 1950's pocket version. I'm impressed that it fired up. You find the most interesting electronic equipment, I never find the cool stuff here in AZ.
The mystery device is a flux capacitor used in time travel. Thanks Paul. Thanks for taking us way back when.
I built one of those small displays into my 500 watt WRL transmitter as a modulation monitor. It worked very well. I really enjoyed seeing one of them again.
Those are nice transmitters Bruce! The Globe 500 is a beast.
Just tried the neon indicator + flashlight thing and yup, it works! Cool stuff!
Very interesting, great video. Thanks for sharing Paul!
You're welcome!
That was very interesting, I had no idea that this kind of displays was made.
First thing I thought was the tuning scope for RTTY demodulator.
I have a 1936 Stromberg Carlson console radio I inherited from my Great-Grandfather. It needs a full-on restoration. Would love to send it to you and have the pleasure of watching a CZcams video of it's restoration and modernization to make it even more practical and safe to use today!
My college roommate found a pair of similar devices in flee market. A way cool device you set on top of your left and right stereo speakers, connected to each speaker you could "watch" the music... Had setting on in my speakers for several years in the early 1980s...way cool and fun.
Excellent vid once again Paul... 10/10
Thanx, i was going to say crt and even modulation display. That's one thing that I'm good at is guessing what high tech stuff is. It was a newly posted video but then you went ahead and spilled the beans.
At about 17 minutes, the description of the photoelectric effect being used to initiate conduction in a tube... yeah, it blew my mind. I've seen a neon lamp that would only work when externally illuminated by light of sufficient energy, and have lost most of my hair trying to figure out how to make proper use of the effect. Thanks to your discourse, I still have enough hair to comb over.
Thanks for all the great videos.
Looks to me like it came out of an aircraft. Just loved the throwaway remark later on "the radioactive material fizzled out".
Oh! I have one of those as well I found in a dumpster. Thanks for the info!
It reminds me of a device I saw in a "quad" receiver that thought was really neat. It displayed merely a dot, but as you adjusted the volume of each speaker, the dot moved to roughly demonstrate where the audio "center" of the room would be.
Love your videos man so much knowledge to share thank you!
You're very welcome!
That is an old side viewing argon gas photo tube. It's used in a circuit for a relay type application. 2 of the pins are connected to both caps. Great video.
That would be my guess argon gas due to the purple color. Do these glow purple when energized? Photo electric sensor 1940-1950 judging from the font used on the tube.
one of THE first takeaways was that you powered up an unknown unit where usually you say that bad caps can cause major issues. and also that as soon as you removed the high voltage you seemed to have your fingers all over it seemingly unconcerned about any possible "charged" caps. still, was cool to watch the process, thanks
"We will control the horizontal. We will control the vertical."
"We can soften it to a soft blur or sharpen it to chrystal clarity"
Unless a bunch of dopes put a Dangerous Buffoon in charge, then WE don't get to control anything any more. And that, my friend, is the outer limit of the Twilight Zone.
very good video thank you from Gary in the UK.
Another outstanding video!
i have an old alarm clock from the 70s that used to have that problem with the neon bulb light for the clock and that photoelectric effect thing is really cool to see
Terrific video as always. thanks!!
Mr Carlson, you are a true geek. You can't spell geek without a double E.
That little Millen scope looked familiar. They used to show that device in their ads in QST in the 50’s.
As for the challenge question, I think it’s some type of phototube, possibly infrared. It would conduct if it was receiving light waves. They were used for door alarms etc before photocells.
Must be a a phototube and if it's from RCA it must be a a 9xx series. I've seen tubes like that in movie cinema projectors for audio and projector switch mark circuits. Nice greets from Germany🙂👋
Sebastian Weinert that’s what I thought too. I recognized the internal configuration as a phototube and due to its small size I assumed it was for a projector
i already had the time to look for the type. Must be a RCA 921 or 926
Would be interesting to test its spectral response using various coloured LEDs?
I have NEVER seen one in person. Only drawings of them on paper.
Thumbs up always, and a bow, sir!
If you have it, it will work. You da man!
I vote for photo-electric tube. Predecessor to CdS cells. Love the trivia!
That 1cp1 brought back memories. It was used in a Technical Materials Corporation 10kw Navy shore transmitter for syncing the oscillator.
Photomultiplier tube? Fascinating video as always.
I think the 1-52 RCA is a phototube/ gas photocell, used in old proyectors to make the soundtrack for proyected films. Works like a IR encoder today.
Very nice video! I haven't seen your channel before.
Thanks!
Oh, an afterthought. You can make anything work, design anything, and explain it for dummies like me! Thanks
Another note about loctal based tubes. Many times you'll find them squeezed in fairly tight spaces and you can't get your fingers on them to pull them out. The correct way is look for the little dimple on the side of the metal base and push the tube at the top in the direction of the bump. This releases the lock and when you quit pushing the tube will basically just fall out. Of course with this little scope you can't do that but I noticed the base of the tube does have the little bump. I learned this the hard way on the radio in my 1948 Dodge...
Your knowledge is exceptional
Great video Mr Carlson
You are one consummate professional. My hat off to you, sir.
Really cool! Thank you.
I have one of those tubes + the magnetic shield. It was for a mini-oscilloscope project that was featured once upon a time in Radio Electronics (I think) from the '60s. The other tubes used, were 12AX7's. It was a great project, although the CRT display is only 1 inch! I may still have the actual article.
Yup what WB3BJU said below, I had one around here in my tube junk boxes. They were used in sound projectors with a focused beam of light on it for the sound track of 16 mm or other film sizes and code tape machines for teaching Morse code and I am sure other things that used modulated light. Happy Spring Paul, KØOJ
Nice. I love that little scope. It would make for a small handy little modulation monitor for a ham radio station, particularly if you're running on AM and need to check for\
overmodulation, clipping, asymmetrical peak limiting, etc.
Outstanding!!!
Not sure where you're located, but if I ever find myself traveling through your neck of the woods, I would love to get a tour of some of your devices and machines. I'm loving these videos.
I had one of these inn the 70's. It was new. I put it into a BUD box with a simple HVPS and added connectors for X Y inputs, to use with AM transmitters. I don't know what ever came of it. It was a neat device.
I say its a photo tube and I've seen them used in assembly line sensors, (as part of a counter) "magic beam" sensors (used in alarms and door beams) and supermarket scanners.
Hi again, Mr. Carlson !!... Am slightly off topic here, but can you answer this !! :-)
On an 'eevblog' general-chat forum the other day, a member was discussing the re-building of
his bench/shelves for work/test-equip etc., and I commented by posting a pic of 'YOUR' workshop :-)
(It has probably pointed many new people to your CZcams posts, haha...)
Anyway, there were many comments.... Mentioning such things as......
-Shelving & supports for your equipment !
-Power usage / Heat / Equip-Ventilation issues !
-How you wired your 'chained' power-supplies !
-Having more equipment than one may need ?
Of course, if they knew you, and the fastidious way that you throw yourself into your work, to the
point of being a perfectionist and utter enthusiast with your love of older equipment/projects,
then they would love your Posts like so many of us do !!! (Enough FACTUAL crawling!! haha..).
It would be nice to gain some insight regarding the above, so I can report back!!
Thanks mate... Glenn.
I never owned one, but I saw many trapezoidal patterns on these in ham radio publications in the 1960s. If I had one today, I might tend to use it for displaying stereo audio, a great tool for determining channel correlation, or lack thereof.
Still have a tiny crt from a viewfinder lying around, sadly it uses magnetic instead of electrostatic deflection. I still plan on turning it into a tiny analog scope just as a project. Fun things to play around with!! This'll be interesting, thanks for the great content!
I had the same idea, becaus I did taken out a really tiny crt from an old video camera. The crt is about 10 mm thick and 25 mm long...
Nice!! Interesting and fun!
Nice to see the little Millen scope in operation. Kind of thing I always saw in Millen Ads, but never saw working.
This is so cool. I have a small crt based viewfinder from an old camcorder that's basically the same as what you have here. The only difference is it accepts a composite video signal. It needs new capacitors (only 2 or three). But will make for a really neat project sometime. Can't wait to see what you decide to do with yours. It's so much easier to work with than my little 1cm crt.
one of the first things that came to my mind when you described it was it could be used as a tool to determine unknown frequencies and phase shifts if used to view lissajous patterns. I'm surprised you didn't mention that when you up the first pattern.
A), izzat a photo tube from a movie projector?
B) I have a freezer in my basement that used to drive me wonky bcuz th power lamp (neon) flickered in th dark & was on full when I turned th lights on.... I actually did ur recommended experiment years ago to make sure I wasn't going loopy!
GREAT videos! Keep it up!
