2020 has been an absolute rollercoaster and seeing the man, the myth, the legend Dan Gelbart bless our YT feed has absolved me of most of my ill will towards this year
I love this man. He has a rare ability to explain only the bits one needs to tell his story. I wish he lived next door. My dad was an engineer and any answer to a science question I asked him started with pulling out his ballpoint pen.
I wish you had more time to make videos like this. Just so much to learn. I always thought that there was more to the story then what we are being told. Thank you!!
Sir, thank you for the nice presentation. By your narrative I could feel you do have not only a heart of an engineer, but the also the mind and the soul. Well done!
Wow. Such a great story teller. I could listen to this man read me the ingredients on the back of a cereal box and be just as captivated. Thank you Mr. Gelbert for sharing some of your collection and the interesting stories behind them. I'd love to see and hear about more of your collection of inventions and their inventors!!
Your work and knowledge is appreciated and cherished. Thank you for your life's work, and the consideration to share with the world your historical and practical expertise.
I have been to this wonderful place twice, but I'm too busy running a company right now. I try to see all the science and technology museums in the world as they will all close down (many already did) because of low attendance.
Sir I can't thank you enough for the lessons you gave me from your videos. there are not so many people in the world who can convey this information very efficiently and precisely as you do. you are the best teacher I could wish to have. thank you.
Fantastic, I really look forward to new videos from you Dan. I re-watched the spot welding episode over breakfast and coffee yesterday. I appreciate you taking your time to make these and share with us! I would love to spend a day with you learning and chatting!
Dan, thanks so much for taking the time to produce this amazing and compelling educational resource. It's obviously a lot of work; please know that it is very much appreciated. When I did my undergraduate physics degree at the University of Waterloo, we had a much-liked professor whose speciality was the history of science. He would augment his teaching with riveting personal stories like those of Haber and Bosch. Off-topic, I met you once in the early 90s when you were at CREO. I was a graduate student at SFU and my solid-state physics prof - an energetic, industrial battery physicist I'm sure you recall - brought us down for a tour. You generously spent an hour with us explaining development of your optical tape recording technology. Thirty years later, I'm sitting here binge-watching your videos at the Vancouver MakerLabs to improve my own prototyping skills. Stay well.
Those were some amazing stories. I've seen my fair share of old mechanical exchanges, in the basement of a 100+ year old telco. I worked there years ago. I had heard of wheatstone, but had no idea he created a one wire solution. I listened to every word, fascinated. Just like all your videos. Thanks!
Dan, as always it was a real pleasure watching another of your wonderful videos... your knowledge of all things mechanical and otherwise that you share is most appreciated... I had hope that you would do more after your series of 18 around you shop...Thank You Sir!!!
@Dan Gelbart Many thanks for taking the time and effort of making and sharing Your excellent videos. I find them both educational and entertaining, and it's content of this kind that makes UA-cam worth while in my humble opinion. Best regards.
Where to start. A great collection expertly curated. You are an excellent communicator with intellect and an obvious sense of humour. Your anecdotes about Maiman were to me especially interesting.
Thanks for showing us your amazing collection. I would love to see a video on the history of machine tools and foundations of mechanical accuracy? You seem to have a deep knowledge in these areas as well.
all I can say is that l truly love your great kindness ......to take the many hours of work to take the time to give us all the great things you do ....... God speed to you sir.
I have seen some of your machining videos in the past and found them very interesting, but watching you show your wonderful collection and explain the history behind them was fascinating. I would love to see more videos of you taking about the industrial arts.
Thank You Dan, for the wonderful backgrounds and insights to these inventors and inventions. I won't forget these now. I've always felt it's important for us to realize the origins of things and get a feel for the creative geniuses who came up with them. Also, really appreciate seeing your collection and perspective. In reference to the latter part on fraud, I'm Curious about your insights into Royal Rife. Thank you again for what you bring to us!
I need more. Learned so much from every video. Even the ones I had no interest in watching. 2 minutes in I would be hooked. This man is one of the most intelligent people I've ever seen but can still break stuff down so anyone can understand. Man I wish it wasn't over.
Thank you very much Mr. Gelbart for sharing these interesting stories and historical exhibits. I really appreciate your effort and enthusiasm in showing them to us. On a sidenote that might amuse you: "Invigorating" trinkets had a short comeback not too long ago in the form of hologram wristbands made from silicone and a mysterious "negative ion powder". That powder being Thorium, Thorium silicates and oxides respectively. It's getting even closer to the case of radium doped jars (albeit way less funny) when you hear about ceramic milk bottles for babies being made with it. Nevertheless please keep it up. Fantastic insights!
You have such a gift not only for invention and creation, but for teaching as well. Thanks for taking time to make videos like this, Dan. I still rewatch your prototyping series occasionally, just cuz it’s so chockablock with great information.
An antique store in Gastown had lots of those wax cylinders and players, circa 1972. A fun toy to own is a Q-switched ruby (actually Nd:YAG) laser, a surplus tank range finder.
39:20 "...the kelvin galvanometer..." We used them at Caterpillar research in 1964. They were called light beam galvanometers. The machine was called a CNC High Speed Strip Chart Recorder. We recorded signals on 12 track 1" tape at high speed. We then slowed down the replay and recorded it onto the chart...running at high speed. The beam channels were directed onto light sensitive paper that was pulled at a constant velocity and wrapped onto a receiving roll. The roll was later developed in an ammonia atmosphere to reveal the traces. The tape allowed us to find the points of interest on an oscilloscope before committing it to the expensive recording paper.
Mr. Gelbart, I have watched all your videos, I think, and I am a fan and admirer. You have an unusual breadth and depth of knowledge, and you are an engaging teacher. I believe you are involved in the commercialization of 3d metal printing, and I think this advancement will become part of history. I like these new videos about historical instruments.
Thanks for the video. I'm in the process of restoring an Edison Standard Phonograph. I've completed the main unit but it is lacking the horn. Your video gave me a good idea of the size, style, and structure of the original. A little disappointed that you didn't get round to the Curta calculator you had on the desk. I have one that was issued to one of the designers of the UK's first atomic power stations. Curta's story is fascinating.
Thank you, a highlight of any day when you upload. I would, and I'm sure countless others would, love to see you create a device from start and inception to finish and refinement.
Dan What an incredible video - and I am so pleased you gave credit to Joseph Swan for inventing the electric lightbulb. So many people think it was Edison. It always amazes me that films or movies took so long to get sound. You would think film would be harder than sound!
When I think I know the story behind an invention, now common in our world, Mr Gelbart tells me the full story with details I didn't know. I have only recently discovered his channel and am watching as many of his videos as time allows. I've already learned much from listening to him speak. What a great man, I wish I could spend a week chatting to him and learning.
I am so happy you are back. I love all of your content. I would love if you could show us how you build your nice spotwelder. This thing is just great.
I love these topics. This guy is really enjoyable to listen to - I love his style and the way he tells stories and educates. I wish I had had him as one of my engineering professors.
Your channel is fantastic. I guess restoring some this historic kit is part of what you use your amazing workshop for? The copper wire for the transatlantic cable was made at Bolton's Copper Works in Oakamoor, Staffordshire, England, which is about 3 miles from me.
This is a very interesting presentation. I watch your prototyping video series over and over as I enjoy your detailed and clear explanations. Would you please consider doing a video of your prototyping “tips and tricks?” I know you cover many in your series but I would not be surprised that you have many more based upon your years of experience. Thank you for sharing your knowledge and I look forward to your future presentations.
Thank You! I have been the proud owner of an Edison cylinder phonograph, an early He laser, and still have a DeForrest audio tube. I adore 'archaic' technology that is driven by singular efforts of genius. We stand on the shoulders of giants. Oh, and I have have an inexplicable penchant for instruments of quackery.
Thanks very much, Dan Gelbart, your words, knowledge and experience are greatly appreciated whenever they appear and, too, your marvelous squeaky chair (now who invented that?)(37:25). There's a review of the Norbert Wiener book "The Tempter", Random House 1959 in the journal Science published 04 Mar 1960 Vol. 131, Issue 3401, pp. 655 review by Donald N. Michael and you probably have that issue on a shelf there.
You can't imagine how much I enjoyed this. I put the video on TV and it was having a friend telling me some interesting story. Thanks a lot for sharing
Great video! Thank you for sharing your vast knowledge. Please make more! If your lathe ever needs a new home give me a holler. LOL Still dreaming about that thing 5 years later....
wonderful video full of history i will watch again with my son. it is really interesting to know how strangely life works for everyone including great minds. great to see you again dan. take care ps loved the humor too :)
subscribed. I've watched a few of your videos by chance (youtube wants to show me what true accuracy is) and your videos are fascinating. Thank you Dan!
Mr. Gelbart - I love your content, your teaching, and your stories. Please do continue to share as much as is enjoyable for you.
Ditto!!!! :)

When Dan Gelbert takes the time to make a video, you stop what your doing and give it 100% of your attention
Albeit two weeks late I stopped what I was doing and watched.

Please please, Dr. Gelbart, please go to the Metiers Art Museum in Paris and make a series on the scientific instruments and models there.
I have been to this wonderful place twice, but I'm too busy running a company right now. I try to see all the science and technology museums in the world as they will all close down (many already did) because of low attendance.
In one hour, I learn from Mr. Gelbart more than I have learned my whole life. Thank you sir.
Mr. Gelbart it is so much joy to watch your videos, please keep recording more.
Nice to have you share your personal collection, we are thankful you did this it is very interesting to see you share these items. Lance & Patrick.
I just wanted to say, never stop making videos. They are by far the most enligtening videos on youtube. Thank you!
Prof. Gelbart: your channel is right up there with UA-cam's very best. My sincere congratulations.
Mr Gelbart is great to have sharing your knowledge again. It has been a long time. Please the videos coming.
This content is just a cut above. The rare artefacts, the details, wonderful! Thank you Mr Gelbart!
