TI Calculators Play Movies
ipapusha writes "TI Calculator enthusiasts rejoice. A few weeks ago, Dan Englender released a new flash application usb8x. Usb8x is a driver that interfaces with the On-the-Go USB port in the TI-84 Plus and TI-84 Plus Silver Edition. It is designed to be used by other programmers to create drivers for a variety of USB peripherals, including a keyboard and mouse. Already, ticalc.org's own Michael Vincent has interfaced his Lexar JumpDrive to play The Matrix's famous lobby scene. (mirror) ."
Here's another mirror if necessary:

Yeah, but does it run linux?

I must be old. I remember the time where calculators were used to do calculations and even plotting a nice graphic of a function.
Slashdot, fix your code or at least hire someone who is competent at it to do it for you.
I'd ask if it'd run OSX86, but there's way too many buttons. Maybe if it had a scroll ball, though.
i still remember getting one of the first external hard drives for the TI-85. some home grown kit with zshell drivers. it was awesome.
so what calculating functions would need color graphics? like the code editing software that automatically colors tags and modules, could there be a benifit to a color display in high end calculator. Aside from playing movies that is. :)

I had a TI-99/4A that hooked up to a TV and it never played movies - you could only change the terminal colors with BASIC!

...TI calcs have been able to play movies for a long time now. TItanium MultiMedia (TIMM) encodes a movie file to a native format for playback on TI calcs. Of course, this new project is much more impressive if it is decoding standard .avi / .mpg files on the fly.
Some things clearly must be done... just because you can.
It looks more like the Matrix than the Matrix...
Just in time for my senior year of high school...
"I wasn't playing games on my calculator... honest!"
This sig left blank for page turns.
I want to see how it looks on a TI-89.
that this was one on a TI. It would have been much cooler on a HP. Still a nice hack though.
I don't want to start a holy war here, but what is the deal with you TI fanatics? I've been sitting here at my freelance gig in front of my calculator (a TI-89) for about 20 minutes now while it attempts to invert a 7 by 7 matrix. 20 minutes. At home, on my HP48 running at 4 Mhz, which by all standards should be a lot slower than this TI, the same operation would take about 2 minutes. If that.
In addition, during this matrix inversion, The calculator will not work. It has ground to a halt. Even BBEdit Lite is straining to keep up as I type this.
I won't bore you with the laundry list of other problems that I've encountered while working on various TI calculators, but suffice it to say there have been many, not the least of which is I've never seen a TI that has run faster than its HP counterpart, despite the TI's faster chip architecture. My Casio FX-100 runs faster than this 12 Mhz machine at times. From a productivity standpoint, I don't get how people can claim that the TI is a superior machine.
TI addicts, flame me if you'd like, but I'd rather hear some intelligent reasons why anyone would choose to use TI calculators over other faster, cheaper, more stable systems.
*Throws out DVD Player and Laptop*
I don't need these anymore! I've got my TI-84!
The dithering looks like crap. My old HP-49G supports grayscale, what about TI calculators?
Mea navis aericumbens anguillis abundat
The ti86 has an interrupt which is called ~186 times per second. By toggling the graphics viewport every two then one cycles, you could get a very realistic-looking four level greyscale setup. Do the newer models no longer have such a feature? Or is this down to slower CPUs?
Someone with enough skill to program this chose fame on /. over adding to his or her portfolio of game mods. One is a basically useless gimmick. The other could actually be worth a damn and people would enjoy using it.
I'm not sure if this particular "matrix function" is going to be smiled upon by college linear algebra professors...

I must be old. I remember the time where calculators were used to do calculations and even plotting a nice graphic of a function.
You're a young whipper snapper if you "remember" plotting a nice graphic. The true old coots will remember way back when punching in 710.77345 and turning the display upside down was about as much fun as a person could have on a calculator (this trick doesn't even work on the newer bit-mapped font-based calculators). Of course as technology improved, I wasted many an hour playing "Moon landing simulator" on an HP-25 (until I turned the calculator off and lost what was in RAM).
Two wrongs don't make a right, but three lefts do.
Funny, on old Russian calculators you could make
an upside down something that roughly translates
as "suck d*ck" (07931505), although some letters
are latin and some cyrillic. Ah, the memories.
CmdrTaco: You know, we haven't had the chance to use that great 'Blue and Red Pill' icon for the Matrix section in a while. I really miss that. They were good movies, and while some might argue that they don't deserve their own section and icon, I believe they are truly a geek phenomenon.
ScuttleMonkey: Hey, why don't we post this story about using calculators to play movies. Some guy played The Matrix on his TI, it's just the excuse we need. Now everyone who visits the homepage will see the icon and think 'Wow, something about The Matrix! I am interested in that story.'
CmdrTaco: You know, that's just crazy enough to work. Well done ScuttleMonkey, when you get home tonight there'll be another storey on your parents' house. You can finally move out of the basement. Now, all we need is some news on The Hobbit movie and the One True Ring will shine on the homepage for all to see!

Of course, USB is nice and all, but the video-on-calc thing has been done before. By me

WHO NEEDS SHIFT WHEN YOU HAVE CAPSLOCK/ DAMN1
not sure about the 84, but the 89 uses a motorola MC68000 12Mhz part.
:~)
I have personally had problems take more than 30 minutes to solve on the 89. Plotted ODEs which took 10 minutes to refresh, etc. Things that didn't matter enough to break out the cursed Matlab.
More common, using a solve function on a rotation matrix can take a few seconds (more than 10, less than 60), but is something I commonly do with the calculator.
The 89 is actually as powerful as most thousand+ dollar math packages. Matlab requires an expensive plugin to do explicit, and it SUCKS at it (okay, entering values sucks, the solver is fine). And so on. It is just plotting that sucks, as.... well, thats a damned small screen
I know the TI-86 has a 6 mhz CPU. I also know that you often had to wait a damn long time to plot some functions in multivariable calculus. But no, there's no math beyond geometry, so of course they don't need the SIX MEGAHERTZ OF RAW POWER.
WHO NEEDS SHIFT WHEN YOU HAVE CAPSLOCK/ DAMN1
Does it come with 5.1 Dolby Surround? :)
I dont know about you, but I'd rather not wait an extra 30-60 seconds for my second derivative to come up or graph when I can get it faster. It certainly helps on exams (eg. AP -- inwhich test timing is brutally enforced). I also *think* the TI-89 has a faster processor and for quite some time, but just didn't have a usb input.
I believe the right answer is:
"All I want is a calculator that can calculate".
or something.
Hence part of the reason for TI emulators.
I used to write Basic programs on my TI-83Plus in Calc class....now they can watch matrix.... How much learning can they do?
-Palal
For the record, the 84+ uses a dual-speed 6/15MHz Z80.
And the number of people found jacking off watching their calculators dramatically increases...
Trading games on your calculator is a thing of the past. Take it one step further and trade pornos! Instead of playing Mario in class, you can watch him strip! That is, if it suits your tastes.
What I want is a 'keyboard' mod -- turn the TI-89 into a keyboard HID :~)
That would rock.
TI Calculators break the rules of tech - they don't really get much more powerful, and definetly don't get cheaper with time. I bought my i-89 about 5 years ago, for 140 dollars. I just checked and it's 136 dollars (for titanium - it has some more memory and usb) on Amazon. As far as i know, no TI calculator has come out that is the same size and more powerful, and prices have not come down at all. Does TI really have that much of a monopoly on the high-end calculator market? I thought back then that TI graphing calculators would run 10 times faster and be in color by now, and I know they could be for the price.
Minutes? Pfft, I have had problems for solve() that took over an **HOUR** to do on my TI-89. However, my HP-49G+ took less than 10 minutes to solve the same problem.
+ c=d,{a,b,c}), or something close to that.)
The HP-49G+ uses a 75 Mhz Dragonball, but most of the OS is emulated Saturn code, so some of the math is just amazingly fast, while most of the stuff is just reasonable.
(If I rember correctly, the problem I was trying to solve was solve((a*x^2+b*x+c)*y^2+(a*x^2+b*x+c)*y+a*x^2+b*x
If I have nothing to hide, don't search me
Had four or five that never solved -- all sine/cosine functions multiple lines (of written text) long. Didn't say unsolvable, just ran and ran and ran, until I started not caring any more :~)
:~)
;~)
And that is using 's1,c1,s2,c2...' etc instead of (sin(a), sin(b)) etc.
Wasn't shocked to not get an answer.
And yeah, I am hoping to hear of a 'suped up' 89 one of these days. Maybe I should check out the HP, but damn I would hate to have to get used to yet another input device
Cheers
You can actually buy those cheap chinese calculators that you see sales people use..
They have huge number keys for the numerals and +-*/ and =, and THAT'S IT!
Online backup with Mozy, sounds like Ozzie, but more!
I had a TI59 in high school, to which I had added a joystick as well as an interface to control my room. With the joystick, it was possible to play games like moonlanding where the printer would be the screen. The calculuator was programmed to turn on and off the lights in my room. A screenshot of the two peripherals. Of course, there was some surgergy necessary, but the TI59 had survived all.
It only took thirteen years to come up with something that has the same crappy resolution of Atari's Gameboy Pit Fighter port.
Okay, so it is cool and the content itself way better than Pit Fighter. Whole new way of graphing a matrix.
If my grammar and spelling are off, I am [distracted/tired/careless] (take your pick)
...but I won't be scared when it's just (extremely ninja-cool R-rated) video. I'm still waiting for someone to hack audio on these calculator things.
When someone makes a T.I. grapher chirp "yeah you know they call me T.I. but You Don't Know Me" then I'll be scared of the professors. Or scratching my head in confusion.
You can hold down the "B" button for continuous firing.

Slashdot's first reaction to VMware
"If you can watch the Matrix... you can also watch pornos."
Already done, years ago. Back in 94/95 a friend of mine had 'porn images' on his calculator. I remember being impressed that they actually pulled off shades of gray with the imagery. Turns out they did a neat flickery trick with the image to simulate that.
Sadly, the lack of image quality on the porn made the shades of gray more interesting. Still, it made the nerd clique a little more popular for a day or two.
"Derp de derp."
It is evident that TI have now won the calculator war against HP. In the 80's, HP were clearly winning at the top end with the 41C and 48SX. What happened?
Here are a few suggestions:
1) HP were winning at the top end, but paid insufficient attention to the bottom end. TI got the cheap school market, and once graphing calculators became a cheap commodity, the top end evaporated, and TI held the bottom.
2) RPN was loved by many geeks, but presented too much of an entry barrier to neophytes. HP tried to counter this by using algebraic notation on their low-end (starting around 1990). Was it too little too late? Did the lack of unity through the range hurt them?
3) Fiorina dropped the ball. She killed a vibrant part of the company because it didn't fit her printer-and-PC-empire vision of the company.
(I've been a long-time partisan of HP calculators, and have a collection of about 20 of them.)

Hi all, thanks for the comments. I'll make a few myself:
:)
* First: Thanks Google. usb8x is a Summer of Code project. Google's support meant I didn't have to find a real job.
* A greyscale movie would definitely have been better than a B&W one. But the point of Michael's demo was proof of concept for a mass-storage device driver. That's pretty darn impressive as it is, in Z80 assembly with no OS support. I'm sure someone will come along and write a pretty version soon.
* Some more details about the hardware platform: The TI84 Plus has a 15 MHZ Z80 CPU and a 96X64 monochrome display. You can fake greyscale pretty well by swaping planes. It has a 2-bit serial port, and a full-speed On-The-Go USB port. Unfortunately the OS doesn't provide any support for USB device drivers.
* OK, so I'll admit: this was mainly done for the "it's cool" factor. But there are useful applications. As silly as it may sound to you, students these days do plug in keyboards to their calculators to take notes on. Or at least TI would certainly like them to, and now they don't have to buy the ridiculously expensive TI branded keyboard to do so. And TI calculators are actually quite useful if you're in the field collecting data with a Vernier probe. Now you can carry along a USB thumb drive and not worry about running out of space for your data.
* Besides, it's cool

Move over Sega CD, Helllo Ti-84+.. Sweet pixelated goodness
Seriously I never wanted to the see the day when Slashdot would be home to WMV files. An Open Source sponsored website is posting propietary file formats that play like crap on Linux and Macs. I for one will not support this.
Who cares? It's playing at ~1/3 full framerate and is barely recognizable.
This was almost interesting, but then I noticed that there was a strange pattern in the wood in my desk and I got distracted.
What were we talking about again?
I currently have no clever signature witicism to add here.
My first *real* digital calc used a nixie type 7segment display..
Nice cool orange color.
The 2nd was green, some other sort of gas type display..
---- Booth was a patriot ----
I have a HP-49G and I loved the thing. It got me through College Calculus without a problem.
The best thing about the HP-49G? For people like me who came from a HP-38G in high school I could use the normal algebraic mode instead of being forced to adapt to RPN of the 48G. Yes I know real men use RPN but I couldn't adapt to it.
*sigh*
Brings me back.
Am I the only one who had the sudden urge to tilt my monitor to read 710.77345? Ahh, the crick in my neck!
...seriously, if you're worried about playing movies on your calculator, you have more problems than /. can help with. Sure it's a neat trick, but it's not practical.

I'd ask if it'd run OSX86, but there's way too many buttons.
I hear there is a rumour Apple are thinking of releasing their own calculator to help spur iBook sales in schools.
The iCalc has the same number of buttons as a TI-84, but as consession to asthetics, they arn't marked but are instead all a single unified service in a 'brushed metal' finish. Thankfully, contrary to some initial concerns that were expressed, this turns out not much of a problem because it's been intentionally optimised to perform and output the result of a single operation operation (6 x 7), additional operations having been removed so as to avoid confusing novice users.[1]
[1] Though further rumours abound this is in no small part due to the sourcing of Intel for the core chip design and that unresolvable heat disspation problems cropped up when attempting more complex operations. In fact, internal testers have reported that after extended usage, they have noted rounding errors in the units they have received (resulting in the system displaying a result for the calculation of 41.999 (recurring)).
i had to relearn how to cod for my reciprocal function problems on a ti84. but for some reason for me, i think in an rpn mindset. even a conlang i wrote was an rpn type grammar.

So in essence, they've turned the latest TI calculator into a palm pilot?

I'm working on a robotics project, and have a serial (RS232C) interface to my bot's AVR Mega uController. I was looking for a serial terminal that I could interface to it, when it occurred to me that TI calculators use serial interfaces. Does anyone know of a serial term that would turn a TI calculator into a dumb term?
I've heard of FTerm running on Fargo on a TI-85, but can not find a download site.

I love these little Casio's. No graphs - but I've never really needed those. These little $12 USD calculators are amazing, and do integration and derivatives within limits, as well as statistics easily with very little wait time for such a cheap calculator. I used to use the TI-36 ($20 USD) until I found this little guy. Also solves up to 3 variable equations and allows inputing of formula's with variable prompts for solving a single equation for many data sets. I doubt I'll ever go back to the TI calculators.

but they don't have the marketing forces to make it happen ...all engagded on the printer front.
But they're slipping on this last point; thankfully they know it. Hopefully are doing something about it
Yeah. They DRM the printer cartridges. And increase ink efficiency while decreasing ink capacity, so instead of printing 500 pages with one 48ml cartridge you can print 100 with a 5ml one (and pay the same per cartridge). And yes, they are doing something about it. "Cut the dead branches".

I flopped in one of my engineering exams in the university, just because of Casio. No, actually because I broke my HP48's LCD and borrowed my brother's Casio without checking it out first. After years of RPN/RPL, algebraic operations with complex engineering equations... Argh... I hate those cheap pieces of shits. Give me a real calc, give me a new HP48! :)
The only thing I can think of is that a PDA is a bit more expensive. But then comparing the higher end calculators with the lower end PDAs, that doesn't seem true.
A PDA is bound to be more flexible, and have a sheadload more software, and benefits from the economies of scale - there must be many more PDAs sold than fancy calculators.

In the early 1970s when the oil shortage was a big deal and people still thought big-ass calculators with red numbers were pretty nifty, this joke made the rounds:
"142 Israeli soldiers fought 15,469 Arab soldiers for 5 years for oil rights. Who won?"
On the calculator type in 142 X 15469. When you enter the "=" key the result is 710.77345. Now turn the calculator upside down for the answer!
Yeah, it's pretty lame, but remember that people still thought calculators were pretty freakin' cool. Whoa. Words on a calculator.
Is it possible to have that video in something else than a proprietary crappy format from M$ ?
VLC doesn't play that here. And I'm quite sure that Ti84 doesn't either.
I much prefer 5318008, myself.
As do I, but the point was usually to use up the whole 8-digit display. Of course, for 10-digit displays, 5800877351 was popular.
