Any help VERY much appreciated

p.s. I should have said this is in effect a new machine, used for about five minutes!

]]>I am relatively new to the Casio comunity but in the last few weeks I learn a lot on my own and I am now pretty familiar with the Casio SDK and C.

So if you have questinos I am here.

Here is my first project.

You can download the project from my GitHub:

]]>I recently went to a second hand selling site named... well it does not matter. A seller had a CFX-9850GC PLUS along with a TI-83 cheaply.

The TI had some keys not working, almost easily fixable.

While the CFX-9850.... Well done CASIO.. There is no protection between the 4x AAA batteries and the PCB, just the PCB green coating... which led the calculator inusable. I had to use some sandpaper to sand down the corrosion.... Then I saw that the keys were working.

I knew the Casio had some Self-Test thing, which is F6 + a b/c + AC and I could test all the keys.

Then I used some nail polish to seal the sanded PCB area around the batteries power input terminals. The calc smells nice now....

Now at least if the batteries leak again, the nail polish should prevent the leaked battery juice from making damages.

My humble option is that the screen kinda sucks, too dark for me. My eyes are not what used to be.

My questions are....

I want to make an homemade cable-to-pc cable. Where do I find information to make one? I read I could connect the terminals of the 2.5mm directly to the RX/TX/Ground but I need graphical schematic wiring.

What tool I need to use to capture the screen?

Thanks.

Basically, I have a Casio FX 82-MS 2nd Edition and the hacks that work on the first edition don't work on the second (obviously). In these three years, has anyone found anything that works on this calculator?

]]>

The calculator can do this kind of calculation:

80 - 10% = 72

Thanks a lot

Thanks so much for any help!

]]>I install FA-124(Version 2.04) and download CAS.g1a.

I read manual but I can't import '.g1a' file.

It must choice only *.g1m/*.g2m.

Help me!

]]>I think i found a secret mode on the casio fx-82MS. It allows you to have calculation history and a few more stuff.

1- press shift + clr

2- press 3

3- VERY quickly press = and on

4- if you dont do it fast enough it wont work, and you might have to do it multiple times

if it works, the screen will be dim and instead of a "0." appearing, a "0," will appear

is this something special or?

lets say you did below calc

2*4=8 then if you press + (or - or / or * what ever) it says

ANS+ But in my old 5500 it was

8+ (it was writing result of previous calculation which was 8 not ANS)

I want it to do as 8+ not ANS+ because if i want to get back to lets say i did

8+5=13 then get back and wanted to make it 8+7 (not 8+5) it gives me 13+7 Because ANS changed to 13 but i want to be able to go back exact line and i cant do this in 5800P

Any way to do that?

]]>If you need more resistors you can iterate on the if statements.

from math import* a = float(input("R1 Value = ")) b = float(input("R2 Value = ")) c = float(input("R3 Value = ")) if c == 0: firstOneOver = (1/a)+(1/b) solution = (1/firstOneOver) print(solution) if c > 0: d = float(input("R4 Value = ")) if d == 0: secondOneOver = (1/a)+(1/b)+(1/c) solution = (1/secondOneOver) print(solution) if d > 0: e = float(input("R5 Value = ")) if e == 0: thirdOneOver = (1/a)+(1/b)+(1/c)+(1/d) solution = (1/thirdOneOver) print(solution) if e > 0: fourthOneOver = (1/a)+(1/b)+(1/c)+(1/d)+(1/e) solution = (1/fourthOneOver) print(solution)

The fastest algorithm for greatest common divisor calculation. Pretty annoying that this calculator doesn't have Intg() and Mod(). But you can at least emulate them with code.

]]>I don't know how to call this program but I used it to set prices for things in games where you can only exchange integer amount of currency and items.

So for example lets say that 3 fubars costed you 5.46 jubas to make and you want to sell fubars with profit between 15% and 20%. You would type 5.46/3 for A, 1.15 for B and 1.20 for C. Then the program will tell you that you need to sell 6 fubars for 13 jubas at an ~19% profit.

You type your code on the left side using standard keyboard symbols, and it will replace some of them with unicode symbols that look like those that exist in Casio calculators and put it on the rights side where you can copy it from.

The editor is made with fx-3650P II in mind because that's what I use these days. Any symbols that I am missing and that you want me to add just message me here or at the email on the webpage.

]]>This is the same program as this one: https://community.casiocalc.org/topic/7379-statistical-significance-calculator-fx-5800p/

C is the count of experiments you did.

B is the probability of an experiment being successful.

A is the number of successes you had during those C experiments.

Given these three it will tell you what is the probability that you'd get at least the same number of successes by pure chance. For example if you get a result of 0.994 that means that there's a 6/1000 chance that your successes were the result of pure luck.

Additionally if you give 0 for A, it will instead tell you how many successes you'd need to have in order for the result to by less than 1% probable to be pure luck.

]]>It prints prime factor then exponent until there are no more prime factors.

]]>It asks for an initial guess X. Then it will print the current Y value (the one that we're trying to make zero) then the new X guess, then again Y and so on, until Y=0.

we use the classpad with the screen-reciever app to show our students how to work with the classpad. But this only works on an older windows 10 machine. As soon as i plug in the usb-cable und select screen-reciever, windows will only detect a mass storage device and it won´t work. Any ideas or suggestions on how to fix this problem?

Thanks from Germany,
