Here's an idea...for those of us who would like to see our calcs become even more useful...it shouldn't be impossible to rig a remote signaling device emitting a beyond - human - hearing tone, have the calc wired with serial-like cables (no solder, plugged in instead) and have it be able to try to come toward the signal. Heh. A homing calculator, rolling toward your desk in the middle of the test, avoiding walls and such..wait ... oh no... HEY, WATCH YOUR FEE..*step* *CRUNCH* *sob*

I think that's the kewlest thing ne one has done with the TI-86. It is also the most useful. I have only one question is this an automated robot or was it given instructions suring the contest? I haven't done much ASM programming for a while and I never was much good. Could someone maybe comment the source too (for us ignorant C++ programmers)?

That is completely awesome! Or as my friends and I say, "That is the non anti chronic!" I just have to ask one thing, who in the world could beat that? I mean geez, what the heck did their robot do, the friggin' Olympics! Gee whiz! If I was running the show, you would have won, in a hardcore kind of way!

Wow Guys this is really neat. I always dreamed of doing something like this with my little calc. Looks like you beat me to it. :-P I dont know nearly enough to interface my calc with something like this, but if I did, damn you better watch out. Nice Job!

Is there any extra info on how he built this? I want to do this too!!!

You know I just can't get over this. This is a great example of the capabilites of a graphing calculator. Now if someone would only create a remote control robot... using a TI-86 or 89 with MINIMAL hardware modifications as the controller.

It would probably be quite easy to make it remote based. Since his robot already uses the standard TI linkport, you could build two IR links and hook one IR link to the robot and the other to the calc. You wouldn't even need to change the program. It would just suddenly work wirelessly.

If you wanted manual control over the robot, then you would need a new program though. Also, IR isn't that great for an object that is going to turn around because IR is line of sight but oh well. =) Until someone makes a radio link, this is all we have.

when the TI-hardware list actually did work on TI-hardware, they DID develop (to a point) a radio driven link. i dropped off the face of the planet for a while so i have no idea where it stands. the last i heard was "well, this and that were working so i guess..."

-KAKE

There has been a radio link made... Its in the /txt/hardware/ archive of ticalc.org... The auther says it works from 30 to 50 feet (can be expaneded if your using a big ass antenna) and uses between 90 to 100 mhz (uh oh hate to be receiving top 40 stations on my calc)... I discused the idea with my electonics teacher, he knows little about RF so if anyone here wants to update the plans i would ask that you
1. increase the power
2. change the spectrum to a typicly unused block
3. maybe have an LCD screen of the operating spectrum.. the one now just has coil control

Now there's an idea if you can have digital readout of the spectrum why not have a TI86 scanner? You could have it automatically scan maybe 5MHz(since 8MHz have 3 left over for processing the signals, plus you only need to scan every 1 khz or so) at a time looking for raio signals including police band, citizen's band, ham radio, even TV. Hey you could even set up your own SETI station but I guess 8MHz isnt enough for that. That would be some petty kewl stuff to do.

Great Job David! You did a great job on your robot. Thanks for showing the power of the TI world. Again, Great Job!

hehehe, are you thinking what I'm thinking? Me and my TI 89 are going to TAKE OVER THE WORLD!!! Once I learn assembly that is...

Get outta here, you schizophrenic. (j/k)

I think the term is megalomaniac

No, I think the term is just PLAIN SAD.

Great Job!! Isn't the prettiest thing to look at though. (From what I can tell from the pic)

Heh Heh. i'm one step ahead of you. heh Heh... Push "clear" and I destroy a small country... Pust Tan and I get, well, tan. Push convert, and you change genders :)

press "sin" and you gotta go to the priest. press "exit" and leave life.

press "0" to go to the TI headquarters to tell them what a great calc the 86 is. press "1" to tell them what a lousy calc the 86 is. press "2" to ask them what the hell they thought they were doing when the made the 86. press "3" to ask them if you can legally marry an 86. press "4" to tell casio to (oops, can't swear ]:-) ) off. press "0" leave this moronic menu.

Hey Destructo86, you killed it. It's not funny anymore.

Is there anyone out there who could build and program a decibel meter for the ti-89??? ...Or even make a RTA (real time analyzer)?? e-mail me if you know of someone who could do this.
Thanks

This could be possible... You would have to build a A/D converter and hook it to the calc, the make the proper program that reads the data coming from the A/D converter...
