Other Calculators / Black edition of NSpire CM-C CAS

« on: January 20, 2013, 12:57:52 am »

This model should have been found long ago...
The black one now has a CAS engine.
http://education.ti.com/zh-CN/china/products/graphing/npsire_cm-c_cas/features/features-summary

On taobao, the CM-C and the CM-C CAS have almost the same price.
The CM-C costs 980~1180 yuan (158~190 USD), and the CM-C CAS 1100 yuan (177 USD). (Unlike those very cheap NSpire Clickpad, here are the price from official TI agency.)

Other Calculators / Need Help! Battery for PLT-SSH1

« on: November 24, 2012, 11:45:44 pm »

After the nspire color, i found another PLT-SHH1 prototype on taobao!
And I noticed that all that prototypes are from 佛山 ,Foshan Guangdong.
Maybe there is a recycle center?
http://item.taobao.com/item.htm?spm=a230r.1.10.1.bDIuar&id=20629844499
However, the model doesn't include the li-ion battery. Can I DIY the battery by myself?

Casio PRIZM / Chinese text reader and IME on 9860 (by diameter)

« on: August 12, 2012, 10:41:01 pm »

Here are some Chinese programs on 9860, just for fun!

I have got diameter's permission to release his Add-Ins.
There is a E-C dictionary by Wudy but I haven't asked him for permission to release it here.

User guide of the IME:
Copy simspell.g1a, hzk12.df, pinyin.py to flash.
Run simspell, press optn to use the IME and press vars to input punctuation.
The font file hzk12.df is shared by the text reader and the IME.

User guide of the txt reader:
Put txt files in flash or sd card, run the add-in, press left or right key to select file.
BTW, Anderain and Diameter is the same guy

Casio Calculators / Questions about .g1l files

« on: August 12, 2012, 08:15:28 am »

Diameter, a programmer in China, developed an Add-In for reading Chinese txt files. Now he is working on Chinese localization of 9860. There is a Russian Language Add-in which released long ago, so similar things may can be done to Chinese.
Here are some questions:
1. How to make *.g1l files? Does CASIO provide any software?
2. Does the g1l file contain a full font, or just "tell" the OS to display the characters that stored in the system?
3. Are there any limits of the font, for example, must be 8x6 large?
Thanks!
And sorry for my bad expression of English

This is an example of Chinese display of 7x7 characters.

Site Feedback and Questions / why peanuts?

« on: August 01, 2012, 07:44:37 pm »

I wonder how the tradition of giving peanuts to newcomers formed? I guess maybe it's because, according to the hitchhikers guide to the galaxy, one will lose some protein after the teleportation. Is that true?

Other Calculators / Does anyone own a CASIO FX-991DE PLUS?

« on: January 11, 2012, 01:08:17 am »

I didn't know this kind of model until today...
http://www.amazon.de/Casio-FX-991DE-technisch-wissenschaftlicher-Rechner-nat%C3%BCrlichem/dp/B0050OTQ42

It seems to be the most powerful scientific calculator of CASIO... I mean, the most powerful one in all CASIO scientific calculators.
And I really want a photo of its PCB~ or maybe an emulator?

Math and Science / TI has a bad CAS, isn't it?

« on: October 14, 2011, 08:12:51 am »

TI using a bad CAS on its 68k and NSpire series.
Both of NSpire CAS and TI-89 titanium can't solve:
integral 1/(sqrt(x+1)+sqrt(x-1))
But both Classpad and hp-50g can...

I wonder what BAD CAS does TI use?

Other Calculators / NSpire OS 3.1, the new dictionary

« on: September 25, 2011, 09:00:28 am »

A few weeks ago, TI released a new OS3.1 of NSpire, which contains a dictionary. But before using the dictionary, you should install two dictionary files by Teachers' Software first. And here's the two files.

-The dictionary icon only appears on OS 3.1 for CX. But the size of non-CX OS file is even larger than the CX OS file. So I wonder if someone can crack the non-CX OS to use the dictionary feature.
-You can open the .tco and .tcc files by 7-zip. Maybe we can hack the dictionary files and make an on-calc wikipedia?

Other Calculators / The Way To Upgrade CASIO fx-82es To fx-991es For Version B.

« on: August 15, 2011, 01:22:41 am »

<This is something that people in China who has fun with calculators discovered several years ago.>
<CASIO scientific calculators, especially fx-82es is absolutely the MOST POPULAR calculator in China.>
<In fact, fx-es series have serious bugs and because of that, we can have fun with it.>

http://youtu.be/EaBY-ZkZJNA

I hope we can find some bugs like this on TI's scientific calculators...
[well, the largest bug is, TI use Toshiba T4x processors.

*Sorry for my double posting...
Here is the emulator.
