OT - does anyone remember credit card torches?

[David]

I have a strong memory of torches with the same form factor as a credit
card, so they would fit in a wallet.

I've had a quick look but can't find any on line so far.

Does anyone else remember these?

Thinking of which, back in the 1980s I had a Casio credit-card calculator
less than 1mm thick, called the SL-800.

It was fiddly but worked quite well.

I still have something very similar, except it's a Systema EX4. The
layout is slightly different to this one which is a Systema EX2 and
appears only to have 2 solar cells, whereas the EX 4 has four cells.
Still works, given a reasonable light source.

The Casio really was thin at 0.8mm, whereas a credit card is 0.76mm
thick. I suppose it was a demonstration of what they could mass produce.

As far as I remember, Casio's later credit-card models were two or three
times as thick, like many of the competition.

Now I'm becoming nostalgic ... after having had three slide rules, I
bought this as my first calculator.

And physics. Maybe some engineering applications. They had their place
in applications where accuracy was not particularly important.

They're cute, I have loads, and was an "expert" user. But they are

You would enjoy the round slide rule then.

https://www.ebay.ca/itm/255963555516

The person who owned one of those, claimed they
could do some maths as fast on that, as on a
push button calculator.

It's a bit like Rubiks Cube I suppose, the people
who practice at it, are crazy fast.

My slide rule was made from bamboo and the bamboo
seems to be suspended in some sort of other material.
I couldn't make sense of the grain structure.

The bamboo makes it slide, and the material is inert
enough to avoid distortions of the material over time.
It can get a bit sticky at times (the slide action).
It's somewhere in the house, but I can't remember exactly where.

Loading Image...

It's only intended for carrying a few digits of accuracy,
but for the people who still use things like that, it's
sufficient for shop work.

The good slide rules, were not department store items.
You could buy all-plastic slide rules in the department
store, but those aren't worth owning (they could warp
if you were careless). The bamboo ones are a bit nicer.
The face was finished in white celluloid.

They came with a leather carry case, and the leather carry
case could be fitted to your pants, as a kind of "ornamental
sword". But the novelty of wearing it that way wore off
quickly. And as programmable calculators had just come out,
the slide rule disappeared entirely. The programmable calculators
also had a loop for your pants :-) Always know your
customer. Rule of thumb -- if you own something, fasten
it to your pants.

Of my collection, the ones that have fared best are the plastic ones,
Faber Castell and the like. Wood is hopeless, they have all warped more
or less. The one metal one is OK, a Pickett, but not the nicest action.

The super accurate ones (I have Otis King, Fuller and Fowler) have all
suffered with age. The surprising thing about the Fuller, which has a
huge spiral scale, is that it is not as accurate as it should be, the
scale is not as well divided as it could be.

Slide rules are one of those items once cherished but made obsolete en
masse fairly quickly and since have laid unused and forgotten in loads of
drawers,desks and lofts.
The generation that used them for real and invested in a well engineered
quality version are dying fast and a lot of these fine items can be found
almost for peanuts in antique shops,boot sales etc .
Apart from looking a nice decorative item there isn’t much you can do with
them.

Optical microscopes are another example, a friend bought one that would
have very expensive when it was made 60 years ago. For £30 he bought an
item in good order that kept his children fascinated for days and directed
their interest away from the games consoles and their phones for awhile.

I've had a quick look but can't find any on line so far.
Does anyone else remember these?
Cheers Dave R

Thinking of which, back in the 1980s I had a Casio credit-card
calculator less than 1mm thick, called the SL-800.
It was fiddly but worked quite well.

I recently found 4 in a drawer, still working, & took then to the
charity shop.

Four of the same calculator? Someone must be a collector.

I have a strong memory of torches with the same form factor as a
credit card, so they would fit in a wallet.

They were promotion give aways which were destined for the bin.
