Does anybody make a machinist oriented calculator ?

or what calculators does everyone use ?

how about a waterproof one ?

thanks
Mike

No machinist oriented one, specifically. I keep a TI fractions capable
calculator on my bench. It works equally well in fractions or decimals or
mixed, and converts freely between the 2. Mine came from Radio Shack. For
calculations in long formulas a direct algebraic entry calculator is handy.
One of these, that is programmable, IMO would make a very good "machinist
oriented" calculator.

And for me. I keep one in my belt pouch (along with a 16C for
other purposes), and a second 15C in the shop, in a Ziploc baggie to
keep coolant and swarf out of it.

Enjoy,

Try Google. Here are a couple. There is software available for your PC too.

In my shop, I use whatever dirt cheap or free POS I have at the moment.
Sometimes my brain doesn't want to subtract 0.916 from 1.241 or something.
Upstairs, I use an HP-15C, which I believe is the absolute pinnacle of
calculators as far as what it can do and user interface. There are much
newer lower power models but you have to program those using a dumb computer-
science-like language. The HP-1XC models, on the other hand, although slow
and battery-hungry by today's standards, you can learn *everything* on once,
and you never forget it. Were I to sell it today (fat chance) it would bring
nearly double what I paid for it. At my last engineering job I had young
engineers gasp when they saw it and say things like "Aren't you worried
someone will STEAL that? Do you know how much those go for on ebay now?"

Say what? I think the batteries in my 15C are about
10 years old at the moment. Are more modern calculators
even *better*?

I have and use a 15C too... however, I change the batteries every 3 or 4
years as I worry about them corroding.

I figure batteries are cheap, 15C's are expensive now.

PS, Also have a 32SII. It does fractions very well, best I've ever seen.

I have a 12C and a 15C, and I change batteries every ten years, whether they
need it or not. g

The battery life in those things is beyond belief. That, and my Fluke 75
voltmeter. The battery (or batteries?) has been in there for at least 15
years, and it's still going strong.

I have the 32SII as well; excellent kit. Do you happen to know if the
manual is available electronically anywhere? I tried HP, but only
non-english versions were available. Thanks for any help.

Yup, they're old NMOS technology, whereas today's are CMOS. Also, today's
voltages are much much lower. - GWE

Yeah, and don't forget possibly the greatest savings is that the LCDs use
ambient light and pose no drain on the batt.

Hmm ... I *think* that the 'C' in the model number indicates
that it is one of the early ones based on CMOS technology, instead of
the NMOS used in the earlier ones -- 35, 45, 55, 65, 67, etc. I believe
that there was a 25C as well, a smaller version of the form factor of
the 35 et all, but with CMOS technology.

Those earlier ones *were* battery hungry. The 15C lasts a very
long time, except when a piece of heavy equipment holds some buttons
depressed for a month or two. :-)

Enjoy,
DoN.

The later ones, like the HP48 series, are much worse on batteries than
the earlier C ones. Probably 50 times worse in terms of current. They
go through a set of 3 AAA cells in no time. The others use much lower
capacity button cells and seem to last forever. I think HP must have
switched from their own ASICs to cheaper off-the-shelf technology.

I wouldn't bet my life on it, but I recall reading that the 'C' in all
those HP calculator model numbers meant they had continuous memory...
something really cuting edge at the time. I think the 25-C might have
been the first with it.

Much later they dropped the 'C', but all HP's (that I know of anyway)
still have the continuous memory feature.

Ah HAA!

I always wondered about that. Where were
the A, B, D, etc? What a throw-back to a
different time, imagine a manufacturer putting
the logic type in a part number, now.

That blew my mind! I never would have guessed my HP11C is worth more than I
paid for it twenty plus years ago!!
What do you mean by battery hungery?! My HP11C has the original 20+ year old
batteries in it! I have it laying in the tool box in the shop. I rarely use
it, but ran across it the other day and it is still working fine!

My 10C is also on its original battery and it's OLD. Don't remember
how old it is. Whenever the HP 21 keyboarf started to double on a
few keys. Must have been shortly after the 11C came out.

Mike,

I use an older HP 11C Scientific, among some other vintage HP's and keep
it in a one quart clear plastic zip lock bag that I replace frequently.
Fold the bag round back and tape it. The reason for the affinity for HP
is that I like RPN and the calculator carries 12 places of accuracy,
whether you can see it on the readout or not.

If I want to lay out 127 divisions around a circle, each step is 2.83
degrees, but calculator will carry 2.83464566929 degrees to be added to
the 2.83 degrees. This very accurate number allows the error to be
distributed around the circle as best as you can read your dial.

Not a giggle; I find a crude 6" slide rule very handy for making up gear
trains for really odd threads because you can 'see' the error on ratios.
