The Crystal Oscillator and Frequency Division

[@brunofonseca9686]

Thanks for the knowledge. Your teaching approach is out of this world. PLEASE DO THE HIGH VOLTAGE POWER SUPPLY VIDEOS!

[@harindugamlath]

Totally agree! Please Please Please!!!

[@GrandsonofKong]

Double DITTO to the above!

[@scottjacko87]

I'd be keen for the HV supply stuff

[@marco56702]

Totally agree!

[@tchristell]

Another vote for HV!

[@alpagutsencer]

hi paul, honestly your videos becomes a some kind of curative medicine these days. Thanks man for your labor.

[@MrCarlsonsLab]

Glad your enjoying! Thanks for your comment.

[@absurdengineering]

I agree. The content is a de-stresser extraordinaire. Magic. I never thought EE content could be so relaxing and yet powerfully informative. I probably sound like a broken record by now, but you’re doing an absurdly good job with these videos, Mr. C. It’s a good decade above lots of other good YT stuff on the scale.

[@sarahhoward9081]

Strange days indeed! Said John Lennon;)

[@toddanonymous5295]

Mr Carlson, I must confess that I always hit thumbs up on your videos at the beginning. You have never let me down. Your videos are priceless

[@MrCarlsonsLab]

Thanks Todd!

[@gandalf87264]

How about a 32.768k crystal driving a 74HC04 which clocks a CD4020 to divide the frequency down to 1hZ. Then clock a CD4040 with that to drive a CD 4515. That's just another way you can do it. It was constantly rubbed into us at university how critical decoupling/bypass capacitors are and to have them as close to the chip as possible. I will never forget it. The professor was a great teacher. It's probably the only reason I graduated.

[@mryoureauser6723]

Just add another div/100 on the 4Mhz chain. Would that be worse to have 4 then?

[@W1RMD]

Since I had to do quite a bit of research and I am grateful to Mr. Carlson for giving us this project, here is to clear up any confusion about the 74HC390 counter ic. Divide by 2: Input pin 1 Output pin 3 Ground pins 2,4,8,12,14,15 Divide by 4: Input pin 1 Output pin 13 Connect together 12&14, 3&15 Ground pins 2,4,8,12,14 Divide by 5: Input pin 4 Output pin 7 Ground pins 1,2,8,12,14,15 Divide by 10: Input pin 1 Output pin 7 Connect pins 3&4 Ground pins 2,8,12,14,15 Divide by 20: Input pin 1 Output pin 13 Connect pins 3&4, 7&15 Ground pins 2,8,12,14 Divide by 25: Input pin 4 Output pin 9 Connect pins 7&12 Ground pins 1,2,8,14,15 Divide by 50: Input pin 12 Output pin 7 Connect pins 1&9, 3&4 Ground pins 2,8,14,15 Divide by 100 Input pin 12 Output pin 3 Connect 9&15, 1&7, 4&13 Ground pins 2,8,14 Also note that pin 8 is always ground and pin 16 is Vcc (+5 Vdc)

[@papaluvspi]

You break this stuff down so well I actually begin to believe I can grasp it at times. Very encouraging! Yes please to HV supply series. Yes please to oven circuits. Thank you.

[@ianbutler1983]

Paul, You are a gifted teacher. You seem to anticipate my every question and answer it. I understand almost everything you teach. Thank you.

[@MrCarlsonsLab]

Thanks Ian, glad your enjoying!

[@seemeknowme]

The "Digital Dial" is definitely my next project! For a long time, I was not convinced that it was within my skill level being discrete logic, but the way you explain it all makes it very easy to understand! Excellent work as always!

[@optimus_lion]

The sound is always spot on my crappy audio setup never clips no matter how loud I go... most impressive Mr Carlson! Thanks!

[@davecompton8414]

Hi Mr. Carlson! This is the first time I've written but I've been watching your videos for a while now. I always give thumbs up. Would love a series on high voltage. Thanks a million for what you do!

[@wsender]

Absolute 100% on the HV supply. I'm really curious to learn more about those. Keep up the great content!

[@litefoot900]

By far the best educator on youtube, the time you take to produce these gems is very much appreciated. Please keep them coming. kind regards from Scotland.

[@MrCarlsonsLab]

Glad your enjoying! Thanks!

[@allanseward7293]

Anxious to see your videos on high voltage PS and the oven circuit. Really enjoy your videos!

[@spbnick]

I too would be interested in the HV supply video. The heated oscillator video would be interesting too, but I'd rather see the project reach functionality first, and then have additional videos on improvements.

The timer IC 555, originally developed from the Swiss Hans Camenzind. Simply but effectively demonstrates, thank you so much!

[@jamesharris9352]

WOW!!! 😯👍 Finally! Someone Who Not Only Builds Electronic Circuits. Yet,... Whom Also Teaches Others, How To Build The Same Exact Circuit In Great Detail!... SO! VERY! AWESOME! 😉👍 Blessings New Subscriber: James Harris... Thank You Paul! 🤗

[@MrCarlsonsLab]

Thanks for your kind comment James, and welcome aboard!

[@cassvirgillo3395]

Hi Paul, Excellent video and explanation. Always a pleasure to watch and learn. Take care, C.

[@GazChamber]

I most certainly would appreciate a video on designing high voltage supply for this project per your comment in the video. I would also be interested to see you discuss constant current sources (sources, sinks, etc.). Thanks!

[@CT1JRZ]

Impossible not to see your videos! Thanks Paul, for sharing so many knowledge. All the best Victor

[@MrCarlsonsLab]

Thanks Victor!

[@5Perf65mm]

The high voltage design/construction series would be great! I really enjoy learning from your excellent videos.

[@nando_br]

Nice explanation. You show us a huge knowledge in simple words!

[@ishimwehonore7436]

Mr Carlson I appreciate you are good teacher thank u god bless u

[@1604max1979]

A video series on high voltage power supply's would be an interesting topic to follow. You are doing great!!

[@TheTsunamijuan]

yes please, More videos. I have been looking forward to more content from you.

[@emilalmberg1096]

I will gladly follow your build of an frequency counter!

[@TheRangerDale]

Yes paul enjoy the flick very clear to understand. Yes Paul I would like to Follow along with you on the Temp control Heater Idea.like always thank you for your Efforts of understanding and knowledge .73's paul

[@MrCarlsonsLab]

Thanks Dale!

[@skycarl]

Wow Paul, this is great. And I am sure I am not alone when I say It would be great to learn how you build a high voltage supply. Thanks as always. Carl

[@Vinceguy000]

Mr. Carlson you are the man!

[@andrec9186]

Hello, you really have a way to explained so we can understand easilly. I really like all your videos and I play them all the time to show my friends how good you are. Keep doing some more interresting videos.

[@MrCarlsonsLab]

Thanks Andre!

[@FlyingShotsman]

Great stuff Paul; you're a wonderful teacher. Many thanks. Please add my vote for the HV PSU and OCXO videos.

[@MrCarlsonsLab]

Thanks!

[@rciancia]

Great video Paul.. Good to see you posting again - as always love your informative videos and truly appreciate the time you put into them. Its not easy so thank you .. Ron

[@TheCrawlingBananas]

Hi Paul! Thanks for the wonderful presentation as always! I'd be 'highly' interested in a high voltage power supply series! Cheers!

[@evanrenberg2682]

Yes, please do a series on HV power supplies Mr. Carlson! 👍🏻

[@kosimov1]

As you mentioned in this video, I am writing to say that I would really enjoy video(S) about old car radios. Especially, I am intrigued about "mechanical rectifiers, which you mentioned in this video. I think I can imagine how it would work, but your way of explaining things would probably be better than I could figure out! I am a fan of you, so do a good job! (I just threw that in to get jollies. I am handicapped so I don't get out much). (Before I'm done with KZbin, I'll probably read EVERY WORTHWHILE VIDEO here! Maybe I ought to download them!)

[@BigTone0777]

Very informative video as always. My appetite for learning electronics keeps growing with each of your videos that I watch! I would love to see a series on high voltage supplys too. Looking forward to the next instalment 👍

[@richardgoebel226]

Please do a series on High Voltage power supplies. A variable power supply for experiments with tubes could be useful for learning how a tube works rather than just watching it on You Tube or reading about it.

[@Max9507]

Awesome idea Mr Carlson, step up transformer theory for old car radios is a fascinating subject. Really enjoyed the repair video on that Ford radio, old car radios are built like tanks and have very sensitive receivers. Thanks and keep up the great work, you are a fine engineer & educator.

[@christopheralbano3570]

I would love to see a series on HV power supplies. It would be especially nice to see more concrete examples of effective methods for decoupling your HV systems from your LV control systems, and go into the theory a bit.

[@MichaelLloyd]

I'm definitely interested in the HV supply video. My 1N14 Nixies and I are looking forward to your next video. I also have 100 of the K155ID1's but it sounds like you aren't going to use those.

[@MrCarlsonsLab]

100! Wow, your set for a while.

[@tm80notgoodwithnames58]

I would like that HV supply video to my possible nixie clock :D Keep up the good work!

[@shana_dmr]

To be honest usual way it has been done in past was just transformer tap, one diode and filtering capacitor, not much of a design;) But doing a step-up converter for battery devices is of course an interesting subject.

[@MichaelLloyd]

Beyond set. It was one of those all or nothing deals and I couldn't pass it up. I couldn't afford to buy a Nixie for each one that's for sure.

[@valordk]

Really nice multi-tutorial. Thanks for having us at the lab today.

[@owenaero]

I love the way your videos are broken down and well explained as well interested in the mechanical rectifier

[@billmoran3812]

Hi Paul, I've been scratching my head for a while on this whole issue of frequency division. Although I've watched many of your videos, I must have missed this one. It's exactly what I was looking for! I want to use the 1 Hz signal from a GPS receiver to keep a 10 MHz frequency standard from drifting over time. Commercially produced GPSDO's are very expensive. I'm trying to develop one that is accurate, but not too costly. Off to order some IC's !

[@nickzambrano]

Yes a video series on oven controlled oscillator design would be awesome!

[@esnam6557]

Thank you very much for delivering the steps very clear. HV Power supply video will be as interesting and useful as this one for sure.

[@DanafoxyVixen]

Definitely keen on a video dealing with HV power supply's and Vibrator supply's. Keep up the great videos!

[@roymercer9065]

Sir you have a natural aptitude for teaching! I very much enjoy your videos. I would love to see something from you on OCXO's. A bonus would be how to control it with a GPS to make a 10 MHz GPSDO to use as a test equipment reference.

[@MrCarlsonsLab]

Thanks Roy!

[@therealtime-o]

So nice to hear that you wanna make a series in high voltage power supplies. I'm interested in nixie tubes in combination with arduino / raspi. Its so hard to find a (simple and easy) stepup from 5V or even 3V to (more than) 190 V. Thumbs up to your Videos and sharing your knowledge with us!

[@JBFLY89]

Definitely interested in a series on high voltage power supplies!

[@llsdigitek]

Paul, Another Mighty fine video... Looking forward to the HV switcher video... Ya make my day with these videos for an old retired engineer. So much so ya have sparked me up to refurb my lab with HP test equipment and get super active! Many Thanks !!! Lloyd-DigiTek-WA9NLA

[@intotheblue50]

Really enjoyed this video, thanks. More please.

[@pneumatic00]

Always enjoy your videos, Paul! Last weekend I got two kewl Hewlett Packard pieces really cheap because they weren't working. A hp 711A which is a 500 volt 100 ma bench supply that I have wanted for a long time because it is small and will fit under the "monitor bridge" on my bench. (I also have a Fluke 407 which is an excellent p/s 550v @ 300 mils but a brute! I used to have a Lambda 71 like yours, also a brute, but it got grossly damaged in shipping and it had a lot of hard to source parts in it so I junked it.) The hp 711A was a great big $5. While I was at the seller's place he brought out a hp 521 which is a 4-place decade counter with the 4 x 12AU7 (5963) tube plug in decades. Always wanted one of those, for no good reason, but for $10 I didn't have to think about it very hard. So I get them home and gradually variac them up...and after a few hours of ramping up the line volts, they sort of worked, sort of didn't. Power supply only went up to 270, counter was frozen. So I opened them up. I remembered in another video you pointed out bumble-bee tubular caps as "always suspect". Each item had (only) 2-3-4 of those and after lifting one end, half of them in fact measured leaky. I shotgun replaced them all and both pieces began working fine, needing only minor adjustment. Power supply now makes 530, counter self-tests good. I will cook them for a while before pronouncing them fixed, but the before/after difference was quite obvious just from those caps. So that was great advice on those bumblebees and I thank you!

[@MrCarlsonsLab]

Glad you got that equipment working. You have some nice older stuff there!

[@bobvines00]

Paul, please do make videos about oscillators & high-voltage power supplies. Also, I'd always wondered where multivibrators got their name, but assumed the name was from much earlier technology. Could you do a video on (multi)vibrators? Especially if you have access to one of the original mechanical vibrators?

[@MrCarlsonsLab]

Thanks for your input Bob!

[@SquantoTerror]

Another great video! Great instruction style. I always get excited when there's a new video out from Mr. C's Lab! Thanks so much for sharing. And yes, I would love to see some HV power supply vids...

[@MrCarlsonsLab]

Glad your enjoying!

[@bobfuller]

Definitely interested in the HV power supply video!

[@kosimov1]

Please excuse me if my remarks or questions here are too personal, but I have been playing your videos quite a lot lately, and I have become intrigued by your entire "setup"! I find myself wondering about you, so perhaps you would be kind enough to answer a couple of questions: -- Are you an instructor or perhaps a teacher or professor of electronics? If you aren't, you should be! You have an excellent way of breaking down complex questions and issues and then presenting your results verbally on you tube. I sincerely believe you have unique teaching talents! While you do valuable work here to contribute to the knowledge and understanding of many who watch your videos, you would be of even greater value if, in addition to what you do here, you also taught young people with your tremendous understanding and technical knowledge! You're probably already teaching somewhere, but I wanted to mention this in case you aren't. I have learned some things from your videos which I am very grateful for. Even though I have a BSEE degree, some of the things you have taught me in your videos are things that I have wondered about for years, which did not come up in my college studies. Thank you for the great videos you make! Please, KEEP 'EM COMING!

[@woodywoodlstein9519]

Larry Holmes I literally think he worked for secret government projects Cuz he never answers these questions. !! And maybe just for suspense Like when Spielberg waited like 20 years to release ET on home video. Either way. I dont blame ya Mr Carlson!

[@erikdenhouter]

"You're probably already teaching somewhere...." Is that not obvious ? He is teaching on youtube, and you wonder on youtube where he is teaching. Making these video's is REALLY time consuming, no time for activities elsewhere I think.

[@TRXLab]

excellent tutorial Paul! Thanks for sharing . Take care 73

[@MrCarlsonsLab]

Thanks Peter!

[@lmaoroflcopter]

definitely interested in HV supply! love watching your videos, thank you for sharing your knowledge.

[@TheRadioShop]

Paul that was fun to watch. You really sparked my interest on this one. I have lots of those chips sitting around here, Off for four days so may just go ahead and build the circuit up. Will be fun the play with. Got to get on line and find me some nixies. Thanks for sharing and always interested in what ever series in the future you come up with. Buddy

[@MrCarlsonsLab]

Thanks Buddy!

[@NivagSwerdna]

@4:32 Definitely nice to see a nixie power supply design. There seem to be many variants of designs on the internet so some ideas around why a particular design works would be very interesting

[@donaldfilbert4832]

Great video Paul! I would be interested in seeing the HV supplies.

[@stefflus08]

High voltage supply, absolutely Yes Please! I've been fumbling around with driving four 8W UV tubes for PCB etching, and I can't seem to find the right ballast. So I think boosting it from my bench supply would be an interesting route. Got some ferrite rod on order, but I'd be most interested in seeing the different ways you'd boost voltage.

[@hassanburrows8535]

Yes please Paul for the HT supplies, especially if you can pull up something on the old automotive units that would be fantastic. My declared interest here is generating ringing current for old polarised bells in telephone instruments, and some small exchanges did deploy vibrating reeds feeding into a step up transformer. Excellent videos as usual. Many thanks for your continued efforts. Saludos.

[@dzee9481]

Paul, love to see your design around a crystal oven and what components you have selected to make it and why you selected those components.

[@berniken6511]

ovenised? yes please Paul. Thank you for this frequency counter series, brilliant. .................Berni

[@pkplexing]

Another champion video, I would be keen on seeing your oven controlled oscillator gizmo, and pretty much any other video in which you describe your designs or how things work. Keep up the deluxe work :)

[@sean999ification]

Very high quality content as usual. I need a hv power supply because I've bought a load of nixie tubes now! Thanks for all your stuff.

[@MrBuck295]

One thing I have not seen, what wattage resistors is used and yes I would like to see a series about high voltage power supplies I would also like to know where you buy high voltage electrolytic capacitors ,as I need to replace all in my guitar amplifier

[@bundylovess]

Thanks mr Carlson I'm keen on the high voltage power supply as well

[@harveyellis6758]

Another excellent video! Thanks for all the work you do prepare and share.

[@DxsupermanxD]

[@Componentfun]

Definitely interested in your High Voltage Supply series, especially "safer" or low-current-output supplies powered with 9V batteries or similar.

[@MrArfisher]

Thanks,Paul, high voltage power supplies for the old farm radios,as well, would be great to know more about.

[@larryk4mu240]

Hi Paul, Excellent series. Very enjoyable, I’ve started collecting parts for the project. 73

[@x_ph1l]

[@dave858man2]

yes I would be interested in seeing the high voltage supply and the oven please love your channel

[@williamna5800]

I love this channel. Great work and thanks!

[@LearnElectronicsCanada]

I second (or third) the HV supply design video. As for the oscillator and freq div chain, wouldn't it be simpler to buy a OCXO for $20-$30 and use that, or are you planning to make something that will give similar precision/accuracy over fluctuating ambient temperatures? It's definitely more interesting to build something equivalent.

[@shana_dmr]

Buying an OCXO isn't very educational, as it has all the oscillator circuitry already built-in, so you just connect voltage supply and it oscillates. Definitely less annoying though, as all oscilator topologies have this amazing feature of stopping to oscillate in the last stage of your design, because they worked with all parasite capacitances and when you try hard on final PCB design they just go silent;)

[@derekkozel]

Thanks for another clear and fun video. I love watching for the content, but the production quality is also really noteworthy. What camera do you use to film?

[@billlaut608]

When Bob Moog built Wendy Carlos her synthesizer back in the 1960s, it included a "Polyphonic Oscillator Bank" that consisted of twelve oscillators for the top octave, which then ran through frequency dividers for the lower three octaves. It would be interesting to see how you would do frequency division on an *analog* signal versus the digital presented here.

[@mirkomueller3412]

Another excellent video - looking forward to the next one !!!

[@supperslash1376]

I would love to see an oven oscillator setup, OSC's also. P.S. I love seeing any test equipment home-made. Like anything that attaches to an oscilloscope, home made frequency counters, any test equipment etc.

[@cyberzonie631]

Great channel! Love your collection of test equipment too. What about a video on voltage doublers/triplers and switching power supplies?

[@LeapFrog_Radio]

High Voltage Supplies, Yes Please!! Thank You Paul, another great video as always. 73 -"LeapFrog"

[@W1RMD]

The CD4017's I've got are VERY sensitive to supply voltage. I had to fool with the input to pin 14. It seems to like a 100k resistor in series with the pulsed 5 volt output from my Arduino made it happiest. It also seemed a little squirly with the output from my Wavetek function generator from the late 60's, although it behaved fine when I got the correct output from that. Too much OR too little voltage on pin 14 and it won't count. Experimenting on a solder-less bread board is a must. A nice CURRENT LIMITED power supply is definitely recommended. 20 mA was plenty for a single CD4017 and 10 leds. Also, Arduino's are NOT short circuit protected on their output pins that I can find, so be mindful of that. What a fun project!
