    Yup.. It's about the same as if I had asked "I get old computer stuff abandon with me. What should I do with it?" . I give it to people who want or need it.

    In other industries, there is a standard 90 day storage.. After that, they can do with it as if it is their own. If it's legally titled stuff (like a car), you have to request a court ordered transfer of ownership. Something like a calculator? If the owner didn't come get it, it's yours.

How are they junk? A TI-83 can run for months on AAA batteries you can get at the dollar store, doesn't need constant software attention like upgrades, doesn't contain personal information and can't get trojaned or otherwise compromised.

It turns on instantly, does what it's supposed to do correctly the same way each time, and turns off instantly. I have a TI-83 on my desk at all times. The user interface can't be beat either.

MNNorske (2651341) | about 2 years ago | (#41300107)

I still use my TI-85 from my senior year of high school back in 1994-95. It still runs fantastically and is incredibly handy when I need to punch up numbers on something and don't want to fire up my computer. I've probably only changed the batteries in it about five times over the life of the device too. It just keeps going. When I look at the graphing calculators they put up for the back to school sales these days they don't look any more advanced than my trusty TI-85. Just a different plastic molding.

Verdatum (1257828) | about 2 years ago | (#41300149)

Being Junk is debatable. What matters is they retail for $100 and up, and scores of high school math courses require them. My Algebra II class (in 1998) might as well have been retitled to "How to use your TI-83 calculator" Class tutorials often worked buttonpress by buttonpress. I lost 3 of them over the course of my high school career (two were stolen from my bookbag), and this was certainly no fun for my parents.

Yes, I realize the older models sell for cheap on ebay. I purchased my 3rd this way and still have it (I suspect it was stolen too), but when you've got an assignment due tomorrow, and even if you get an extension from the teacher, you risk falling behind, so you often bite your lip and pay Best Buy prices.

I wish they weren't so expensive. They shouldn't be. With the exception of some tiny crappy memory expansions, they haven't changed in like 20 years, yet the price tag has only gone up. I'd love to see some project like OLPC destroy this monopoly.

Re:Give them away (2)

arth1 (260657) | about 2 years ago | (#41300375)

With calculators, appearance is everything. Even small nicks and scratches will knock down the price to a tiny fraction, and because these were both forgotten by careless students and loaned out to others, it's fairly certain that they're not in great or even very good condition, and will lack manuals and boxes.
So they'll be worth very little.

Note: Certain models are rare, and can be worth more. If you have a HP-10C or TI-78 in the collection, you can get good offers, even if not in perfect condition. If you find a TI-88, we're talking thousands.

If the OP doesn't know what to do with found calculators yet the OP works in a school where students would benefit from these calculators, I think we're in trouble. Next time I'm sleepy or hungry and don't know what to do about it I'm going to post a /. article and ask everyone.

That is what I was figuring. You are a science teacher. You have a supply of calculators that you can loan, what else do you need to do with them.

I mean if you have a huge inventory of them you can share them with other science teachers to share too.

Ti-83's while useful they are only really good for 11th grade-12th grade students. Once you go to college they normally require the higher end calculators (If they still do so, I would except they may be using Matlab or Maple)

In theory they could go to an unprivileged school however the idea of giving stuff to a school sometimes causes more political problems then it is worth.

So just share them with your peers who may have a student forget or loose their calculator.

There are plenty of kids out there whose parents won't justify spending $100 on anything educational, so just keep those calculators on hand in your classroom and loan them out to students who need them. In doing so, you're giving underprivileged kids the same resources that more well-off children always have at their disposal, and hopefully by having the same tools as their peers, you can keep them engaged, interested, and learning.

That's nerd-worthy to me.

Re:Keep loaning them out. (1)

If you must have brick and mortar, any pawn shop will have one. Or you could buy a modern grapher like the Casio FX-9750 for $50. TI does run a racket and they offer a vastly inferior product. I have a stack of Casio's and I am amazed at how cheep they are and how much better they do everything vs the same TI-83 that I used in middle school in 1992. I was helping a kid with some simple math assignment the other day and I was shocked at how ridiculous using the TI product was, gave him a $20 Casio FX-115ES from my pile and he's never looking back.

Re:Keep loaning them out. (0)

Best Buy carries them. But "price controlling?" I don't think that word means what you think it means. A manufacture isn't obligated to limit their profit on an item. In the USA, if they can get it, they're welcome to charge it.

Considering how many students carry smart phones now, I doubt TI will be making them much longer. Teachers will no longer be able to loan a student a calculator, so the student will need a $400 phone with $50/month plan to use that free/cheap calculator app.

I studied in America, did junior high, and i purchased a TI-82+ which was and still is an amazing device. However, aside from graphically plotting charts a normal 20$ calculator will do the trick. I can understand that some parents don't see the value in spending 100 bucks if their kids are dumb as dirt. A graphical calculator only really become vital in advanced mathematics. Kids should learn to understand the math and not how to use a calculator..

I still don't see why anyone would need a $100 calculator. I am a Physics student, even been to an olympiad, so I have probably used a calculator more than most of my peers. However, I had a $20 Sharp from elementary school to university, and my classmates had similar ones. In all this time, I've never needed anything except basic arithmetic, angular/hyperbolic/log/exp functions and the value of pi.

So, what have I been missing all these years?

As the author of that hack, I solidly second that suggestion. We also have a bunch of other calculator hacking projects that might interest you, like case-modding, adding features likes backlights, PS/2 ports, a touchpad, etc. There was the FloppyTunes project ( [] ) that lets you play music on a floppy drive with a calculator. Since you have so many calculators, though, CALCnet would be fun to play with, and since we're always looking for people to help with a wireless version of CALCnet, that might be something fun. And no one has written a distributed computation system with CALCnet yet!

I don't know about your school, but in every one of my middle school and high school math classes, students always needed more loaner calculators than they had. (my college banned calculators from math classes, which didn't really hurt since all I took was Calc II).

If you find that students are consistently being responsible and bringing their own, I suggest donating them to another school, so they can get some use from them.

There's not really anything interesting you can do with them - they aren't powerful enough to do anything other than do simple math, or perhaps play a mediocre Wolfenstein clone on (yes, it's real - google "ti-83 doom app").

I am a trifle surprised that nobody seems to have banged out a USB/bluetooth 'calculator keyboard' peripheral(external numpads are a dime a dozen; but I've never seen one with a scientific calculator's complement of operator symbols and things), since building HID devices to spit out whatever keycodes burned into their dinky little processors isn't a wildly expensive process; and would make phone or computer-based calculating a bit more comfortable.

As for dedicated calculators, though, it seems most unlikely: the second you get good enough to help little timmy skip learning in favor of data entry, you can kiss the educational market goodbye, and that is close to being the entire market for calculators, in volume terms... Test administrators can get touchy enough about the pathetic internal storage of the TI-83 and similar, they aren't likely to warm to something that has a radio data link and could trivially be farming out the problems on your math test over the internet to somewhere poor enough that "take a lazy first-worlder's SAT for $50" sounds like a really good idea even to those with actual math skills...

I hope that your school system isn't requiring its students to buy expensive graphing calculators out of their own (or their parents' own) pockets, but that's another diatribe.

If you have more calculators than you need for your own lending program, and the other math teachers (if any) at your school are also adequately equipped, then share them with other schools in your area. There's probably a classroom not too far down the road - perhaps across the tracks? - where they don't have a large number of kids carelessly abandoning valuable electronics.

There's lots of single parents and otherwise poor families that can barely scrape together school supplies for their kids, let alone buy the graphic calculator that they would need to get into a precalc or AP math.

To teach in a district that has no needy kids and can all afford $100 for a graphing calculator. What's wrong with what you were doing and lending them out to kids who need them?

Donate them to some third world country / school? Combine it with a project to collect more calculators, I for example, have several collecting dust that I would gladly donate in such a case.

To loan to his students. That's what mine does. And, who wants to spend $100 on a calculator they're only going to need in one class?

Please keep doing what you're doing. I had my graphing calculator stolen in high school, and was not happy about having to shell out the cash for a new one. I had a test later that day that required one, so I went to the head of the department and she reached into a box marked "graduated" and pulled one out. She put every found calculator that came her way into a box labelled with that year. Four years later she moved it into the graduated box, understanding that the student had since left and would not be claiming their lost property. She simply handed me one and said not to worry about it. A decade later I still use it.

Put some games on them. Or periodic table software. I love TI-83s, mostly because you can put your own software on it. Had some sort of a skating game on mine at one point. Also Tetris, Falldown, Snake, those pyramid puzzles for some reason...

Assembly programming (2)

rasmusbr (2186518) | about 2 years ago | (#41300065)

As a matter of objective fact, the nerdiest thing you can do with a TI-83 is to write assembly programs for it on your PC, send them to the calculator through the proprietary* cable (if you've got one) and run them. If you don't have time to do it then maybe you have a student who has time. Challenge your students to write a simple program that draws something on the screen!

*It goes without saying that it would be nerdier if you built your own cable and used that.

Calculator porn? (0)

Anonymous Coward | about 2 years ago | (#41300091)

My friend used to draw some mad calculator porn using the draw program. Since you work with kids maybe porn isnt the best idea. Maybe a LOST sign across four calculators that you could hang. Or you could do math formulas and hang it in the classroom. You'd need external power sources. I'd second the comment to ask on boing boing or apartment therapy since slashdot users seem to not be very artistic based on the comments so far.

Loan them to nerds-to-be (5, Interesting)

Sarten-X (1102295) | about 2 years ago | (#41300103)

A story I've kept for years as inspiration. A hundred points to anyone who can find the source:

One of the best parts of high school was when my math teacher took a spare TI-83 and let me use it exclusively for the whole semester, under specific terms: Do something awesome with it, and he'd let me skip my final.

Three weeks later, I'd written a small text adventure. A few weeks after that, I had a trading game with a complex market. By the end of the year, I had turned that same trading game into a graphical one, where the goal was to sail around the world buying low and selling high. The more money you had, the more likely you were to be attacked, which also took place in stunning 1-bit color graphics. The game's actions were controlled through a menu system, which was also used to launch the game (as opposed to the various tools I'd written to do my homework for me).

He was impressed, and I was inspired. When I started applying to colleges, I finally knew what major I wanted: computer science.

Keep loaning out those calculators. A student might need one, and not even realize it.

hattig (47930) | about 2 years ago | (#41300169)

Actually, I am surprised at the lack of tablet/smartphone graphing applications that replicate and enhance the functionality provided by the dedicated graphing calculators.

Loaning them out when needed seems a perfectly suitable solution to the problem. Maybe get them to write some games - that was popular back in the day.

Or to draw the batman logo as an algorithm.

Kids interested in PROGRAMMING! (1)

Anonymous Coward | about 2 years ago | (#41300327)

The TI-83 and especially the 84 are powerful easy to use and learn devices for programming.

In highschool my algebra teacher actually went into loops, and the math text book had blurbs how to program and i taught myself BASIC that way. Youve got an 8x16 character lcd screen, OR something around 94x180 pixels you could directly address. ie collision detection in a 2d game.

Hey developers, what if you had a pocket sized device you had to carry anyway that you could program on with 0 hurdles. I've passed my calculator down to my brother who used some of my programs as they were and learned from the rest to make his own.

If this inspires you, get an 84 not an 83, its got a better screen, and isnt slow, its got twice the speed and storage. Both are bottlenecks on the 83.

More than just arithmetic (0)

Anonymous Coward | about 2 years ago | (#41300367)

Eventually, some of those calculators may stop working, Why not expand your pedagogical uses beyond the math/science classroom? Hand the old broken models off to a club like FIRST and let your students get some experience taking apart electronics- even among prospective engineering students, surprisingly few people ever get to do that as kids. Or hand some live calculators off and let your students learn programming.

Helping students to avoid paying for wildly overpriced electronics is a noble goal, but remember that these devices have more classroom uses than just arithmetic.
