Turn a TI Graphing Calculator into an Intervalometer and Create Time Lapse Videos

Step 7 Enjoy!

Here are a couple finished videos I've made using this method.

It would also be nice if anyone who knows how to program later model calculators (Ti-84, 86, and 89) could write some programs to do the same thing. I could probably write the programs but i wouldn't have any way of testing it.

Have Fun!

I used this method just a back in 2009 to make a time-lapse plane construction video over a weekend. http://www.youtube.com/watch?v=QjARFrVcRKM&feature=plcp&context=C39b2812UDOEgsToPDskLvuiKUi0c_6WJh8JoTfJs0

I'm about to use it again for a new plane. Helps a lot with illustrating construction techniques for new students.

Somebody has some idea or recomms for the same project but using HP48GX+ and Nikon D100 ?

I have written a few programs for my TI-84+ Silver Edition. Most of the programming is the same for the TI-82, TI-83, TI-84. I haven't done anything other than write simple conversion programs. If anyone can find me a link or something to more advanced programming for the TI-80 series I will be eternally grateful. If you want a few programs I made, message me.

Can i have the codes for the ti-84 silver edition????

Bumping from below------------------

From Luberack (Mar. 10, 2011)

I also used silentfallen's program below. Very nice! I did notice that the timing seemed to be a bit off, so I ran the program at various times in front of a stopwatch. I put the numbers in Excel and got the slope of the linear trendline that tightened up the timing tremendously. Here's the scale factors you should use for the TI-84 Plus (not sure about others):
[note: "%" should be replaced by pressing the "STO>" button.]
A*750.64 % W
B*750.64-704.12 % X
So here's what the whole program will look like:
.................................................................................
Disp "START DELAY IN"
Disp" SECONDS"
Prompt A
A*750.64 % W
Disp "HOW OFTEN IN"
Disp "SECONDS"
Prompt B
B*750.64-704.12 % X
Disp "HOW MANY SHOTS"
Prompt Y
For(H,1,W,1)
End
Send(A)
Y-1 % Y
While Y>0
Y-1%Y
For(H,1,X,1)
End
Send(A)
End
...............................................................................
hit "QUIT" to save and exit programming

So you would like the coding for some programs I wrote?

[SamG7]

hey thanks alot! i have a question though. if i have a= 600 it will wait about 6 seconds then shoot 3 shots. so no matter what a is it will take 3 shot bursts. Do yuo know how to change how many shots? Thanks you can email me [e-mail]

You combined my nerdiness for cameras with my nerdiness for calculators. And for that, I love you.

[sjoewert300]

+1 :D I love it!

[vakaloura]

Awesome men!!! This is wonderful to do videos on HD but I have no idea if quicktime can handle it (of course quicktime Pro do it). An easier method is using videocameras but the resolution is lower than this method, anyway men Great Job!!!

[macfreak4]

Yes, QuickTime can handle HD. Apple is one of the biggest leaders in the industry, if their products couldn't handle HD no one would use them.

[koldkiller]

Not even true everyone is just to lazy to actually do something and fix up there stuff to conpare with apple.

Great DIY! I just did it with a TI-82 Now THAT's old school! I think it was the first model with the link port. I have a TI-81 that does not.

[Heedle Blambeedle]

My friend has a TI-79 but it still has the link cable

[fkuk]

how did you do it i cant find the buttons i have the ti 82 could you tell me in very simple steps

You inspired me to make a few of my own! Great method, cool technique. Thanks!

[cybervanig2000]

You are some kind of awesome because that is really cool. People like you are what the world needs more of.

[Grmgunner]

lol now all you need is a harness to put the calc in and clip it to the tripod

[tzhme]

This is amazing i tried it and it works perfectly!! Except my tripod is a POS... anyway kudos

[MilotisX]

beautiful man, SICK

Has anyone gotten this to work with TI-86 and Rebel XTi? I followed the instructions here but the camera seems to just focus when its supposed to take the picture as well.

[kennyboy019]

You need to set the camera to manual focus. Theres a switch on the lens that you need to flip from "Auto" to "Manual". Going to give this a shot when I get home!

[arsheffield]

Using a TI-86 requires a little tinkering with the 2.5mm cable.

I found an excellent write-up here:

[willyisnotsilly]

Great, works for me! Thanks.

[bartgrefte]

Nice project! Btw, what (camera/83+) settings did you use with the 1st movie? Like to know how you got that "ghosting"like effect... Bart Grefte ( [e-mail] )

[Jawatech]

BRILLIANT!
