A bit of fun for all you gadget freaks

Ever wondered what's inside an old fashioned mechanical calculator?

How on earth could anybody even begin to design something like that?

I have a strange love of Typewriters, printing presses and Counting machines, In fact I own one of these

(Olivetti) and some other bits and bobs. Thanks for sharing.

Oh I love things like these

That's just crazy

I remember using them in school around 1970. They weighed a ton when you had to pick them up, but they made the most wonderful sound when you turned the
Handle. It sounded like lots of gears all moving into place. I loved that sound. I know, im a sad person

 

[welsh dragon]

...a sad person and a bit calculating

Come on rocky. You must remember them as well, after all you're the same age as me.

I do......and like I you I loved them

Does the Gibson A14 ticket machine float your boat?

These look like Robocop's slippers.

On the nostalgia front I've just unearthed a slide rule and, much to my amazement, I can remember how to use it.

Is it Faber Castell or one of those bamboo jobbies whose name escapes me?

It's neither of those though I did have a Faber Castell. When I peeked in geekiness I used to participate in slide rule calculation competitions that my sixth form physics teacher used to organise. We used to talc the grooves to minimise friction on our slip sticks and stop the jumping past the aimed values which required correction and slowing down the calculations.

I had one - booty from helping my form tutor clear out the mystery cupboard in our form room. I also got an O-level physics text book that was way more in-depth and interesting than the GCSE one I was supposed to use.

It was a lovely thing - I think my dad had it on his desk at work at one stage but I don't know what happened to it. They were bloomin' heavy, you're right. Not very comfortable cycling home from school with one in a rucksack.

It's amazing how you can go from that to a calculator that is no bigger than a credit card and is powered by solar energy.
