My man ... I absolutely love your content! You are a joy to listen to, given your soft-spoken and enthusiastic nature, and this is a master course in human ingenuity. I had no idea that the majority of these gadgets even existed, before I came across your channel! Thank you ... I sincerely enjoy this. :)
...then shalt thou count to three, no more, no less. Three shall be the number thou shalt count, and the number of the counting shall be three. Four shalt thou not count, neither count thou two, excepting that thou then proceed to three.
Something I find on it's way out these days sadly is tactility. The intricate elements of interaction with a device that gives physical feedback on its operations. Take smartphones, in car entertainment etc. Tactility is all going out the window in our new touch era. There is nothing more rewarding than using something that gives feedback and response when you use it, turning a real key in an ignition, a knob on an old car or using a really good mechanical keyboard or even a typewriter or in this case a mechanical calculator. It is so calming, and rewarding.
I absolutely agree with you here! There's not a whole lot of satisfaction in using a smartphone, as compared to one with actual buttons (even though the utility is much higher). One of my "down the pipeline" projects is to build a custom control panel for my smart home equipment, with buttons, LEDs and all that good stuff. More things that must wait until after uni. :)
This was the first mechanical calculator I ever saw. Our math teacher brought it one day to school to demonstrate us the mechanics behind the basic calculations and to show off how pocket calculators used to look like in _his_ days.
Love this video and it's softer sounds, the calculator isn't as abrasive as the typewriters or other calculators. Also enjoy the laid back and close miced way you recorded your explanation. Would love more of these!
I'd never get past the first 5 minutes without going unconscious. Mind you, that would make the audiobook very good value as it would last a long time.
Can you do another video using this wonderful device and the 2dn version of it. Mechanical calculators are amazing when you think about it. I'm going to have to own one of these some day. Thanks for sharing!
Ah yes, now I know why I got the green parrot "boop" video offered to me. I subbed to you after watching the calculator "asmr" video. What a lovely bird.
Man I would love a nice mechanical computer like this but I looked on eBay and they go for lile $1,500. The bigger adding machines are like $50 though, it would've been cool to be able to take this to class though.
This looks amazing, but I can' wrap my head around one thing, When you flip that one tiny switch, it makes the rotation subtract in the counter register. But pulling the rotator up does the exact same thing, but by doing the cool discarding the final carry thing. Why are there two ways to subtract?
The counter register only counts the number of revolutions you make. The Curta will always subtract with complement addition. Pulling the rotator up makes the Curta subtract the amount in the setting register from the amount in the accumulator register (where the result is kept) and registers a negative rotation in the counter register (subtracting one). That switch inverts the relation between the rotator add/subtract setting and what's registered in the counter register. This is useful in case you want to keep track of how many times you've subtracted something, such as during subtractive division. Hope that answers your question!
What do you typically use to take care of your devices internals? - I'm sure they don't need much up keep, but in the event you want to do such a thing - what is used for lubrication and protection? Silicone, White Lithium?
First I wanna preface this: If you get a Curta, do *not* lubricate it. If you're not 100% sure what you're doing you might destroy it. If I need to lubricate a device I usually use sowing machine oil. Unfortunately I'm not sure exactly what's in it. Generally speaking the machines won't need much upkeep, but a "new" machine has likely not been used for years and needs some TLC. Apart from that, q-tips, rags, pressurised air and a good ratchet screwdriver tends to be the only tools you need. (although I did need a hammer one time...)
Ineteresting, thanks. Ha that hammer incident sounds interesting. Anyway, I love these Curtas, they look so cool and the complexity in such a small package is amazing.
Very spiff and spiffy. Fine mechanism - what goes around, comes around. Do you suppose you can work it one handed with practice (over a hard pillow - no bouncing)?
I bought it from a very nice American gentleman. It came clean and in pristine condition, as you say. I haven't seen any defects on it. Poor fellow wanted to give it to his kids, but they weren't interested in it. All I can say is that it's in a nice home now where it's well appreciated.
@@1stSpyGuy I'd love to have one, even if just as a curious showpiece! How can someone not find a little numbermill like that fascinating. And I suck at maths. :D
They were really commonly used by Formula 1 pit crews to work out whatever kinda math those guys need to do. It was very useful for them to have a portable calculator. Curta's marketing material would seem like it billed itself as the "calculator for the executive businessman on the go".
This is very cool, and I'm fascinated by these mechanical calculators. One question, though: why did you choose 496 as your starting number for addition?
I pick numbers kinda randomly, but leaning towards numbers that promote carry operations. 96 would create a ripple carry in a multiplication.. (9 + 9 = 18 and 6+6 = 12)
Division and chain multiplications are generally hard to follow unless you have a useful real-world application to go on,. Those are the ones where I pick my numbers in advance to make it more comprehensible. Addition, subtraction and simple one-time multiplication are not hard to follow. It's easier to pick some number at semi-random,see above. You give me way more credit for planning my videos than I'm due.
Fair enough! Unfortunately in America in 2017, certain things will make me sit up and take notice (if you don't know why, google the number). I wanted to be sure it was just coincidence. Thanks for explaining.
@@maddiemonster the number 1488, which appeared due to the multiplication of 496, is well-known as a neo-nazi symbol. it's just concerning to see it, generally.

A TF2 player with an interest in old, geeky mechanical stuff. My man.
"i think we can all appreciate a clean number" lol sure can awesome video!
have you ever considered doing audiobooks? your voice is incredibly relaxing
Joel Zerr the way he says opportunity is awesome
An "asmr" channel had uploaded his video, because of just that
Matt Giles when does he say that?

You say the word opportunity incredibly, you have a great accent
"I think we can all appreciate a clean number every now and then." - Words to live by.
Can you do another video using this wonderful device and the 2dn version of it. Mechanical calculators are amazing when you think about it. I'm going to have to own one of these some day. Thanks for sharing!
How much did you pay for this exact specimen?
I see them going fro 700-2000 USD
this device is really cool, wish I had one
Can I have it?! Pretty please?! 😂
I NEED one of these!
Also, really nice presentation box for it! Beautiful stuff, man. Thanks for sharing it with us.
Ser ut som en tidsinställd handgranat. Skruva 3 gånger för 3 sekunder till explosion.
It looks like a grenade, also your voice is very relaxing

And how do you attach that thing to a line and a fishing rod? Seems like a decent mess coming.

When you are a artillery soldier in an area where a EMP exploded this will come in handy.
I wonder if you can still aim and shoot modern artillery without the computerized parts...
You should get a Babbage analytical engine and do a video of how it works...
Yeah, I'll just go down to the nearest Walmart and get one.
Who did you buy it from? It seems in pristine condition. Was it cleaned?
I bought it from a very nice American gentleman. It came clean and in pristine condition, as you say. I haven't seen any defects on it.
Poor fellow wanted to give it to his kids, but they weren't interested in it. All I can say is that it's in a nice home now where it's well appreciated.
@@1stSpyGuy I'd love to have one, even if just as a curious showpiece! How can someone not find a little numbermill like that fascinating.
And I suck at maths. :D
Where did you get the case?
Came with the Curta. The guy who sold it to me made it himself, apparently.
thanks for the reply -- shame they're not for sale!
I saw this and thought that this is awesome so I looked online to buy one and they all sell for over $1,000! I’m so sad :(
Why are they so expensive?
For what are they used? Military?
They were really commonly used by Formula 1 pit crews to work out whatever kinda math those guys need to do. It was very useful for them to have a portable calculator.
Curta's marketing material would seem like it billed itself as the "calculator for the executive businessman on the go".
Is it supposed to look like a grenade, or maybe i should stop drinking coffee at 3am?
My guess is both ;)
This this was Great 👍
It looks new, but I'm sure it's old. When were Curtas manufactured and in use?
Mathew Woodard 1948-74
And based on the serial number, I'd say this particular one is towards the center of that range...
Вот раньше делали на века, и до сих пор не зависает не глючит.
