Re: Have you turned your calculator on at all since the summer began?
Tzazak  Account Info

I helped someone out with a bug report, brought it on one of my vacations, and wrote most of my story on it. I also got it out when Corrupt got updated. When I copied my story into word and changed : to tabs, it came out to 12 pages.

Uh, font size is limited to "big" or "small". It's more likely to have been in "small" or atleast in that size when viewing. This is unless the programmer made their own font+size. ;-)

Also helped with a bug report, I think, in that I reported one. Turn "Parenthesis Assistant" on in Omnicalc 1.10 then try this problem on an 83+:
"((8 nCr 4)/(4nCr1))/(12nCr5)"
~reply to this if you can also see a problem in doing that.
+It's still winter here and we're at school so I pretty much use a calc every week day.

AMS: 0,1,2 (basically 8, 12, 16 on a computer). You can also make custom fonts.

Also, he was referring to the font size on the computer that when printed would have resulted in a 12 page paper that didn't overflow the calculator.

I tried it. It wont let you close the brackets.

It seems that you cant close brackets on any expression with nCr in it..........

The flaw is that parenthesis assistant fails with tokens that have spaces in them.

This bug has been fixed in Omnicalc 1.2 (recently released, see link)

Just checked in Omni 1.00 (on a Silver), the problem also exists there; it won't allow you to close any of the parentheses. Looks to me like it resets the "open parentheses"-count to zero whenever it encounters an nCr token...
(Btw, the same applies to nPr.)

In Word there were 12 pages...and there are more than 2 font sizes in Word...Read more carefully...
To stay ON TOPIC with the survey, I have only used my calculator about once a week. I store a variable called my_money on my 89 which is about 0.89 and is the percent of my money after taxes I get to keep. I use the calculator once a week with this formula: HoursWorked * CurrentWage ($7.50/hr) * my_money = money that I get on my next paycheck. :)

I just started learning it yesterday, and found it to be even easier than I expected!

I haven't looked into Tkinter much. Would you recommend it over PyQt?

Tkinter

I haven't tried PyQt, but I'd reccomend Tkinter becuase it's part of Python, so you can easily run it on computers with python installed.

Ive had this same problem occur to me with my Silver loaded with Omnicalc 1.10. I got so annoyed that I had to turn it off. Once we stopped learning probability, I turned Parenthesis Assistant back on. :)

I have a 10 page story it MSWord in 12 point Times New Roman (Windows), single-spaced. I regularly put it on my 83+ under NoteFolio (several AppVars), with games to spare.

Oh yeah, no kidding... I write stories and stuff like that on my TI-89 when I'm bored. I've made some REALLY huge files just from the text editor; I type on that thing all the time! At one thing I had a sort-of journal/diary thing going on when I was bored during the school year. IIRC, a file that I made in one day was over 10KB on my calc. Actually, most of my calculator's memory is taken up by text documents.

A rechargable will not fry a calc.
The calc might not like running at 1.2V but that would seem a bit odd - as everything else out there (including cameras, flashes, etc are as happy with 1.2 as 1.5V

I have always run my 82 on rechargables.

What power supply / calc.

Just realised - home made power supply?!
6V
over 4.8V battery pack - you will over charge your cells.
Drop to a 4.8V supply if you you to try that trick.

Better Idea

Two options - put in a diode so they don't charge --or-- find a way to put in five (5) 1.2v batteries so it totals 6v as it should be.

Or if you don't mind a special charger there is always the 1.5v Rayovac Rechargable Alkaline but then you need the Rayovac Alkaline Battery Recharger.

Yea, ive use rechargable batteries in all of my electronics, including my 83, 83+SE and 89, and never had a single problem with any of the calcs and rechargable batteries. I dont see a problem with 1.2 volts because when regular batteries start to get old, thier voltage drops to around 1.2-1.3 anyways. Plus the rechargable batteries voltage is a steady 1.2 volts instead of dropping and theyre more cost effective. :-p The only problem is that when they die, you usually dont get a low battery warning, in which they die that quickly.

That's true--I haven't had any problems using rechargeable batteries either. Any device that doesn't run on 1.2v per cell is wasting a lot of even a 1.5v battery's life. (If you have any devices like that, don't throw the batteries away when it stops working; you can use them in something else that uses less power for a while.)

The low battery warning is where you have to be careful. On my TI-89, I've had more than one occasion where the (rechargeable) batteries have died before the calc even detected it, causing my RAM (and sometimes even the Flash archive) to be lost. So, I just check the voltage of my batteries every once in a while and when they get down to about 1.2v (they start around 1.3-1.4v fully charged) I recharge them.

That happened to my 83+se once, only it was with non-rechargeable batteries. Also, it was when my cousin was borrowing it for the ACT... I felt pretty bad.

How can you survive without rechargeable batteries? I think TI has like an alliance or business deal or something with battery companies and just wants us to waste our money buying alkalines...

I don't think it's just TI... look at all the stores. They have Alkaline batteries displayed prominently all over the place, and then hide the rechargeable batteries (if they even have any) somewhere most people won't notice them.

Marketing at work. :)

Normal internal power conditioner on any calculator, I thought.

However, I also didn't want to risk a $170 calculator by testing this.

My mom used to use rechargables all the time for her graphing calcs, and nothing ever happened to any of them (until one of her students dropped one of her TI-82s down the stairs). ;-)

But really... it's bad for the calculator? If so, that's a good thing to keep in mind...

why would a calculator use a power supply?

Batteries supply DC voltage. There is no need for a power supply to convert AC to DC, although there might be a need for a voltage regulator.

Re: Re: Power Supplies.
ti_is_good_++  Account Info

They have to condition the power, regulate it, and distribute it to various chips. That's a power supply. It's not a bridge rectifier, it's just a conditioner so that the calculator doesn't get fried by non-ideal power supplies (basically degraded batteries or AAAAs or ones dating to the Nixon Administration).

A power supply is a device/circuit/etc. that converts/conditions power for the load in ANY way required-not just 120VAC to 5VDC. Almost every electronic device uses a power supply of some kind.
