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.

Every time I look at one of these I just can't believe they're from the 50s. Like even the font that says Curta looks so modern and the overall material and everything. Amazing piece of awesome engineering. Edit: Obviously the 3D Printed one is amazing as well!

[@DoctorShocktor]

Der Eggad The 50s wasn't prehistoric times. 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.

[@alecwhatshisname5170]

DoctorShocktor there's actually a subreddit for people like you. Reddit.com/R/iamverysmart

[@caseyhayes7510]

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.

If it ever was to break (unlike the real thing) you can always have new replacement parts 3D printed.

[@SH-pc4xt]

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.

Hi Adam, I purchased my first Curta in the late 60's -remember the ads in Popular Mechanics and Scientific American! We used it extensively for TSD rallies along with a Heller 100th reading odometer and a split stopwatch. 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!

[@warpatato]

FeelsBadMan

[@tannerman6851]

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.

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.

What everyone does: "I want to buy a Curta!" *goes to eBay and sees the prices* "Actually no I don't!"

[@erikengheim1106]

Charles I did that and STILL want to buy one. Yes I know it is expensive as hell but they also keep their price well, which means there is not cost really to owning it. You can sell it and get back more than you paid for it. 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]

@@erikengheim1106 Thing is though, as cool as they are they're basically entirely useless. I really can't justify spending that much on something just for the coolness factor.

[@erikengheim1106]

@@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.

Adam you rock on tested and you rocked on mythbusters thanks for all the cool stuff you did in mythbusters and the stuff your still doing on tested and mythbusters has helped me through some tough times

[@Ord3ith]

anyone else immediately think of William Gibson’s Pattern Recognition?

[@MarcusWu]

I still need to finish reading that book -- it's on my night stand right now.

[@xy9ine]

i was unaware of the curta prior to reading that book. was amazed to discover it was a real thing. such a lusty little object. i can't fathom the work that would have gone into Macus' build. kudos!

[@FlameForgedSoul]

It's the reason I clicked the video, nice to know I wasn't alone there!

[@Riva1000]

Oh yea! I read and re-read the book maybe three times. (And all the other Gibson’s books too :) )

[@t3ripley722]

I'm a huge Gibson fan, I've probably read his Blue Ant trilogy once a year for the past 3 years.

[@BobBob-qg4lo]

I wish I could be as happy as Adam is about this calculator

[@blogobre]

Marcus just sold 1000 of them.

[@scottsterling7659]

blogobre where can I buy one

[@MarcusWu]

Unfortunately, the time cost involved is high. I don't know if there's a way I can sell them assembled. Maybe as a kit, but it would still require significant work to manually fit, paint, and assemble all the parts.

[@rouge5140]

Marcus Wu maybe sell a non painted kit whit only the nubers painted? I would buy one even for 500 bucks

[@WillWatches]

Marcus Wu what about the blue prints for the 3d printed model?

[@MarcusWu]

They're at www.thingiverse.com/thing:1943171 If you're talking about the source CAD files, they are on OnShape (cad.onshape.com/documents/57e3f5c529d2af11276b1529/w/eafe4a700fe87f2b71bc3d31/e/a1cecd297d7cbe45e3c24de8)

[@averageanon5504]

Can we just take a moment and appreciate Adam's excitement that's similar of an excited kid opening up present on a Christmas morning. Man, that bring back memories.

[@mpetersen6]

Are drawings available The geek in me yells "that is so freaking cool" The only thing geekier is Clickspring's Antikythera Device he's building

[@MarcusWu]

The machining he does is amazing

[@mpetersen6]

@@MarcusWu Of all the KZbin machining channels the top 3 IMO are Clickspring, Stefan Gőtteswinter, and This Old Tony.

This may just be the most beautiful thing I've seen in my entire life.

[@5chr4pn3ll]

There is a joke to be made here but I will not be the one to make it....

[@kamikazebacon5499]

5chr4pn3ll I mean, it wouldn't "curta" do it.

[@reeceengineering]

I didnt care to much about the calculator but seeing Jamie be so excited and the impressive craftsmanship of the box and calculator was awesome.

[@quebirt]

Some people are going to watch this and think, "this dude is getting way too emotional about a 'thing.'" I hope those people are passionate about something else, and not just dead inside. The history of the Curta. The fact that this guy appreciated it enough to follow through with such a project. The detail and care to do such an amazing job. These people are why we no longer live under rocks. On the other hand, I'm going to throw out every project, finished and unfinished, in my workspace because I will never do anything this impressive.

[@scottresch9912]

We need more people excited about truly historical things. It is the sum of all the things humans have endeavored and accomplished that has brought us to where we are now. And I truly believe the respect and admiration Adam and wu show twords this amazing device and the history behind it is what we all need a bit of in our lives. Get excited, find a passion, learn the history, and evolve from that point. That is humanity's purpose.

[@CecilMerrell]

Yes! There is a great amount of history behind this calculator!

[@keetrandling4530]

Oh, Adam! I'm so happy for you; it's so moving to see the joy in your nerdly little heart!

[@rangnar90]

It is amazing to see how much joy it brings Adam to see special things like this! Really entertaining.

[@Azulineazuline]

Through this channel I learn about a lot of things that I had no idea existed or how where they made or how cool they were and I looooveee to see someone like Adam explaining this thigs while being so excited

[@randomposts6277]

Your episodes make me so emotional. I grew up on myth busters and it has effected my life in so many positive ways. Thank you for continuing to spread “cool knowledge”. 😎

[@jonathanroussos8916]

I have loved my type 2 Curta for many years. Cool to see the printed one.

[@AngieWilliamsDesigns]

I love how how excited you are. Very impressive work Markcus.

[@Swishy_Blue]

Insanity, dedication, perseverance and technique.

[@3931100]

I have a # 2 setting here on my shelf. Being a journeyman Toolmaker I can appreciate the precision of this fine crafted calculator. I bought it in 1968. I would sell it since I am 88 and would like to pass it to someone that take good care of it - for a price.

[@0xteknogeek]

I still have my grandfather's version of this calculator. how awesome!
