Calculator with mechanical keys

[reparto]

I am fed up with having to buy a new calculator every couple of months, are there any scientific calculators with mechanical keys?

hm, I don't think so...simply because the size of mechanical switches would cause a HUGE calculator with the size of a notebook. the only one I am aware of is the "alpsulator" but it has only the basic calculator functions.

I am not fussed about size tbh, I have a large bag which I can easily fit 3 gaming laptops. If only...

well, sadly manufacturers see it different and are all about "the smaller the better"...so it seems you are out of luck on this one.
but when googling I stumbled over this piece of machinery which just kinda fits to the topic but I still link it because I find it very interesting:

I might actually buy that.

I reckon you could do Sin and Cosine on that using some approximated algorithm (its also how computers do it) so it should be usable-ish.

oh, I would too....just one problem: they go for 1000-2000 € on ebay...
if you can find a shop that sells replicas let me know...

Yeah I checked and they are insanely expensive. But a very useful thing to have incase of an EMP blast...
