  • Adam walks us through his collection of analog calculators, culminating in one of his newest favorite objects: a 3D-printed Curta calculator that's a perfect scaled reproduction of the intricate mechanical computer. This incredible replica was engineered and built by Marcus Wu, who started the project two years ago.

    Amazing! My dad was the national distributor for Curta back in the 50's. My brother and I used to demonstrate it at conventions so that my dad could say, "So easy, a child can work it." My dad and brother also repaired them. It was a beautiful, extremely well-made machine. When electronic calculators came in, it put my dad out of business. Fortunately, he was at the age where he could retire. This reproduction is amazing! Like you, I found it emotionally very touching.

Modern typography arose in the 1800s, modern engineering in the 1910s, precision engineering in the 1920s-30s, micro-engineering in the 50s, etc. Yeah most modern design and production concepts began well before you were born, who woulda guessed? And frankly the 3d printed one is less amazing, it's just a less precise duplicate created on a relatively dumb machine.

      DoctorShocktor that's rather ignorant. the point of the comment is that while our styles and aesthetics have changed, the curta retains a modern look. of course the 50s we're not prehistoric, but it's the era is obviously dated. the vast majority of people don't wear beehive hairstyles with floral dresses or pompadours with black leather jackets, yet the curta has an almost contemporary feel to it. as well, i do not understand how the 3d printed replica is less precise; it uses the same schematics and mechanisms as a genuine curta, but in 3x scale and in ABS plastic. it is the same machine in a different medium. and i must say, for a dumb machine in its infancy, 3d printers are certainly versatile enough to make "smarter" machines with relative ease.

      While he was in the concentration camp (he was Jewish), he was ordered to work with the local machine shop to produce this rumored amazing mechanical calculator. The head of the shop actually told him that if his design actually resulted in a working mechanical calculator as Curt claimed, one would be given to Hitler as a present and he (Curt) would surely be declared an Aryan and his life spared. Curt did not want to become an Aryan by any means, but he did realize that turning his ideas into a working device could save his life. So he began to draw the detailed plans based on the device he had imagined he could build.

I just saw the video of the assembly of the mostly 3D printed Curta quite recently. It really shows the complexity of the device and how many parts it has. If it ever was to break (unlike the real thing) you can always have new replacement parts 3D printed.

      Let me explain why.
      It's interworkings are all custom as the calculator is made. Meaning, instead of a normal watch where they're all the same internal workings going the same way. The Kurta is a fully custom gear working. Meaning, if you where to compare one from to the other, they would be completely different for the gear timings. Meaning, a person would have to go one by one and make sure each number worked. On. Each. Slide.
      That is why they cost an arm and a leg.

My initial Curta was stolen when my wife was assaulted and had her handbag stolen- Yes she was my 1st concern but the loss of the Curta a close second...
    Since this time I have acquired 2 Type 1s and 1 Type 2 all in immaculate condition. These are truly one of the most amazing devices ever and a small community that still knows them and collects them. I LOVE the 3D printed version- what an incredible piece. I really want one!

      My main concern keeping me from buying it, is the impracticality of buying something that expensive. You have to verify very carefully that you are getting a Curta in appropriate condition. That it does not get lost in transport etc.
      But if I could meet a person and inspect its condition, I think I would be willing to pay what it costs.

      @@CLaw-tb5gg It is the same as buying art of gold though. Both are pretty much useless, but they are ways of storing value.
      The first time someone made me aware of this was a friend who collected expensive watches. I wondered how he could afford it, but he pointed out to me that, it didn't really cost him anything, as collectable watches don't fall in value.
      That is quite different from say a fancy Apple Watch. They may seem cheaper but after a couple of years an Apple watch will have lost most of its value. The cost of owning something is the value depreciation.
      That is why it is very different to buy an expensive computer and a Curta. Your computer will loose massive amounts of value over a few years, while the Curta will actually increase in value.
      Yes the computer has more utility but a Curta is more useful in terms of value storage than a modern computer.

    I wonder if the mechanism needed lubrication of some kind. It sounded dry and stiff when he operated it. I would be afraid of damaging it, too! (Replacements parts from the maker are just a phone call away.) However, fixing it must make watch repair seem like something done by blacksmiths! Amazing.

    • @MarcusWu
      @MarcusWu Před 6 lety +4

      The mechanism is lubricated with a PTFE dry lubricant. The sound you hear is actually the ratcheting of the anti-reversal pawl against a toothed gear at the bottom. In videos that does sound like it's running w/o lubricant.

    • @thomaslevy2119
      @thomaslevy2119 Před 6 lety +1

      Thanks for the info. I didn't think that you would forget to lube something with so many moving parts. (For those who may not know, PTFE is plastic compatible and will not soften or dissolve 3D printed parts as petroleum-based oils can.)

    • @MarcusWu
      @MarcusWu Před 4 lety

      I don't think a 1:1 scale printer is possible with a resin printer. I've seen the 1:1 scale parts and they are very small. At that size, the resin may not have the strength or rigidity necessary to operate. It would certainly be interesting to try, though. I'm looking forward to getting a resin printer soon.

    Building the Curta using a 3D printer is unbelievable. Of course building the original Curtas was pretty amazing. Seeing that old DataMath brought back memories. I started with TI in 1973. The calculators we were building (almost all by hand) had 3 circuit boards and over 100 components. They sold for $160 at Nieman Marcus. Three years later we were building TI-1200s. They had about 6 parts and sold for $10 at checkout stands. We built 75,000 per day! It was a hell of a ride. I am proud to have been part of a group that put calculators in every school kids hands.

      No. for filming something like this where they only use one camera that would make it a nightmare and take twice as long to film. its so much easier to freecam these types of videos so you can just go in and get an angle without having to take the camera off of a tripod, edit that out afterwards and then put it back on and hope its in a similar spot otherwise the videos would end up jumping around the place... Using a tripod doesnt go with their workflow or the flow of the video so they don't use one... it isn't a one day build or with a guest so they can spend more time on it its just a video where Adam has got a cool thing and they film it.

    Adam: I know you don't read comments, but ... I loved the Kurta when I first saw it. I was able to buy a Model II for about $150 or so, IIRC, in the mid 1960s. As you say, it was obsolete shortly thereafter but it will forever have a place in my heart. (Right along with my 6" Post slide rule that saw me through countless college classes and my late father's 12" K&E.) What an odd feeling ... I think you had it too ... to see something so beautiful and functional and KNOW that it is probably the least sensible way to get the job done today. Thank you for this video ... and your perfectly relatable reaction.
