PC Keyboard with Scientific Calculator Buttons

D

D from BC

I still like using my scientific calculator for electronics
calculations.

I misplaced my calculator one day and decided to try out Windows Xp
built in calculator..
What a pita moving the mouse around to each button.

How come there's no PC keyboards with scientific buttons like handheld
calculators??
(I didn't notice any at Future shop .)

Heck...My PC works with multiple keyboards...
Anybody seen a scientific keyboard + software..?
I want SIN COS and TAN buttons damn it! :)

I do use Mathematica and Excel on occasion but I'm lazy to learn hot
keys and don't like gaming style mousing for little calculations.

Optimus Maximus will be able to have that functionality, if it ever
actually ships and if anyone actually wants to spend 1200 on a
keyboard. (I do, I do!!!)

Wow!!! Each button is a color display.. Arrfff! Arfff! :)

I can just imagine all the CAD icons or electronic symbols on the
keyboard buttons..SIN COS and TAN buttons too in calculator mode.

I liked the Half Life keyboard demo on
http://www.artlebedev.com/everything/optimus/demo/

And best of all..There will be an ANY key!!

So expensive :(...

I use the excellent HP48 emulator from I-can't-remember-where, that has
pretty much all calc the keys mapped to keyboard ones (as labelled on
the calculator image).

Get a real calculator again, they cost next to nothing, you'll sleep
better at night, and you'll be able to take it into the lab or
wherever. Infinitely better than any PC calculator.

Typing sin(something) in C was never very difficult.
If C is too complicated get an old BASIC somewhere.
But I often write small C programs to do some number crunching.
printf() is your friend.

How utterly horrid!

Google has a calculator too, type "sin(1)" and there's your answer,
never have to leave your bowser.
Google calculator even gets the correct answer to the ultimate
question:

Browser? Linux has things like scilab,
google for:
scilab-4.1.bin.linux-i686.tar.gz
and/or read:
http://linuxgazette.net/issue98/pramode.html

I usually have about 8 xterms (or rxvt) open with all sorts of stuff, browser
too.
No KDE crap here... fvwm, just 9 virtual desktops (enough really).

42 huh? ;-)

scilab:

-->sin(%pi / 2)
ans =

1.


-->sin(%pi )
ans =

1.225E-16

Oh well, nothing is perfect :)

So, you want to calculate sin(15)-- key in (on the numeric keypad)
"1", "5" then "S" (or "s"). Three keystrokes, how hard is that?

One should always eschew the lowly desk rodent and "la boule roulante"
for key commands triggering frequently-used functions.

S is for Sin? Wow...only a bunch of other hot keys to slowly learn
over time.. Like the @...

Huhhh...I found the XP calculator hot keys.
I've listed some below..

ln n
log l
+/- F9
M+ CTRL+P
MC CTRL+L
MR CTRL+R
MS CTRL+M
n! !
pi p
Radians F3
C ESC
CE DEL
sin s
cos o
sqrt @
Degrees F2
tan t
Exp x
x^2 @
F-E v
x^3 #
x^y y

I have an idea..
Since my PC can use multiple keyboards..I'm going to buy another
keyboard and stick notes on the buttons.

SIN on the S button
COS on the C button
EXP on the X button
PI on the P button
Sqrt on the @ button <<a little more difficult to remember

But even that sucks because the buttons are all over the place and I'd
rather use a calculator..

So I might get a small handheld PC keypad and just assign every button
somehow.

Maybe wireless too :)

A bluetooth calculator?

You don't have to !

Just type the numbers in from the keyboard. + - / and * all work too.

Doh! ....
Damn...its the lead :p
But math function keys are all over the keyboard, even if I knew where
they were.

I'd like to find a "one hand" blank keyboard and assign buttons.

Maybe 2.. A left hand keypad and an right hand keypad..

For example:
Left hand keypad for schematic control...Right hand on mouse..
Right hand keypad is for math.

Keyboards are great for word processing but seem sucky for program
control were all I'm doing is selecting icons.

It was a joke, pointing out that most people these days don't have to
leave their browser to do anything.
Linux has things like scilab,

and/or read:

too.
No KDE crap here... fvwm, just 9 virtual desktops (enough really).

I didn't understand a word of that!, but I suspect you might need to
get outside more :->

I'll happily continue to use my *real* calculator for most tasks,
thanks.
I can take it with me in my pocket, it's got zero boot time, never
crashes, requires minimal keystrokes, and does not need to burn 100W
of power. The best tool for the job is always purpose designed.

Anybody using a scientific calculator with a USB connection?

Wouldn't it be cool to do this...

Make a calculation on the USB calculator...
1.34*10E-4 Amps squared * 4.87ohms = blah
(Format for 2 decimal places)
Then press one button (on the handheld calculator) which pastes from
the clipboard into a schematic program or sim program.

So I click on each part..punch in some calculations...paste..
Next part..calc calc calc ..paste
Next part ...calc calc calc ..paste

Yeah, cool, but where are you going to source the 4.87ohm resistor
from?
And how does the program know you are dealing in ohms?

Dave.

Normally I grab my handheld calculator, make some calculations and
then I have to type the result in LTSpice for each resistor.
It would be nice just to transfer the result with a button.

Later on I change all the values to closest production values.

Ohms is the default in LTSpice

You'll just have to retype them all again anyway when you re-layout
the circuit in a proper schematic editor so you can make your board.

Cough... :p
Yup...For now..
I just had some trouble with Mulitsim. (Models and some learning
difficulties with the program.)
So I often prefer to do spice with SwitcherCADIII...
Then I do the ridiculous thing of redoing the schematic in Mulitsim
not for spice but just for capture because it's nicely linked to
Ultiboard for PCB layout.
Linear Tech can quote me on that :)

Either I'll get Multisim working for me or I'll learn to format
LTSpices netlist for Ultiboard.

Regardless...I still would like to have a dedicated keyboard in some
fashion to do scientific calculations at any time with results that
transfer to the clipboard.
I did a little googling and only found USB numeric keypads.. No user
defined keys on a blank keypad yet.

Do a search for Console Calculator (ccalc.exe). It's freeware, quite
small and you just copy it over to wherever, no install needed.
