Calculators The original handheld (digital) calculator.

AI Thread Summary
The Curta calculator, designed in the Buchenwald concentration camp, was manufactured from 1948 until around 1970, when electronic calculators became prevalent. It is praised for its intricate mechanical design and functionality, with prices on eBay reaching around $1000. Discussions highlight its impressive engineering, with some expressing a desire to own one despite its cost. The Curta is noted for its compact size, measuring 55mm in diameter and 85mm long, which contrasts with larger electronic calculators. The conversation also humorously suggests its potential as a self-defense tool due to its solid construction. Comparisons are made to other calculating devices, including the abacus and the ENIAC, emphasizing the elegance of the Curta's design. Overall, the Curta is celebrated as a remarkable piece of engineering history.

The original handheld calculator.

Curta

This was designed in Buchenwald, the German concentration camp, the first prototypes built from the original hand drawings worked. It was manufactured from 1948 till ~1970 when cheap electronic calculators came on the market.

I would love to hold one of these mechanical beauties and feel the gears at work! (Can be had for ~$1000 on Ebay.)

There is a article about the history of the man and the machine in the Jan 04 Sci. Am.

WOW!
What an absolutely brilliant design!

I am impressed.
I want one.
 
Yeah, me too! I think I am in love! Unfortunatly they are simply to expensive a toy at this point in my life.

And unfortunately for me, my girlfriend would say the same about me (although she is wrong:wink:).
 
I originally posted this in Engineerind design, cus this is such a beautiful example of a well engineered product, but, on second thoughts. It is not about design. But a really cool and amazing machine.
 
But the real question is: Can it run Linux?
 
What a BEAST! and if someone annoys you, you can club them with it! (see Ivan's thread) THat is really great and i think that it should be made cumpulsory in every home, as a great calculator, and a handy security measure, in case of break-ins.
 
I thought a thread titled: "The original handheld calculator." would be about the abacus. Ever used an abacus, Integral?
 
i was thinking of abacuses (abaci??) but you still have to do the working out anyway don't you? It is just a visual aid i thought...

what a great toy, i would try to use it on a test but of course it probably isn't on the list of accepted calcs lol.

Did you actually look at the dimensions on this thing? It is 55mm in Diameter and 85mm long! you consider this a bludgeon?


I have seen handheld electonic calculators bigger then this. i.e. a TI 9X what ever the number on those huge inelegant monsters is.

It could be a mini-club. Yeah, graphical calculators are also beasts. And damn annoying.

Pretty clever design, incorporating a calculator in the shell of a pencil sharpener. Now... can it still sharpen pencils?

Lets see Texas Instruments make a calculator that dual functions as a pencil sharpener.

Commercialize it: "Broken pencil? Forgot your calculator? Have no fear, Curta is here!"

Does sin fine...for small angles!

That calculator reminds me of the ENIAC . A total monstrosity of a machine which filled an entire room and weighed thirty tons.

Not sure why something that fits in the palm of your hand would remind you of a monstrosity? This little mechanical calculator is about as elegant as mechanical design can get.

A Monstrosity? What could you be thinking!

I must be needing some sleep.. it looked big to me. I meant big as a car battery, not a full room!

Now THAT'S a bludgeoning implement...if i had quite a few like-minded friends with forklift trucks...
