Can anyone make a program that retreives FM radio waves and play them at a certain chanel? I know that you can produce sound by putting it by an AM radio, so why cant it receive radio waves. If you cant make it receive FM can you make it receive AM? Thanks a lot.

Without special hardware, it can't receive (more accurately, filter and decode) radio waves.

What's happening with the AM radio playing what the calculator plays is the same thing that happens when you drive under power lines while listening to AM: it's just interference being picked up by the AM radio.

You can think of it (I think) as the calc is sending an electromagnetic (radio) signal at ALL frequencies, and so the AM radio "hears" the signal at any frequency.

So nope, sorry, the calc can't pick up radio stations without special hardware. You might as well just get a cheap radio.

AM is Amplitude, not frequency

AM -> Amplitude Moduleator
FM -> Frequency Moduleator

Sorry, just a pet peeve

To listen to a different AM channel, you'd have to change the frequency- in AM the frequency changes the same and the amplitude changes, so you'd have to change the constant to distinguish between channels... (I think)

Eh, whatever.

Do you have any idea where you could get the... radio transmitty program music thing?

Oops. I meant the frequency _stays_ the same and the amplitude changes (in AM)... Whoa. O:-)

you're right. and FM changes the frequency-the amplitude stays the same- that's why FM doesn't get much interference

AM uses different frequencies for different stations/channels. The analog signal is modulated using Amplitude Modulation, that is, changing the amplitude of the carrier wave based on the signal.

Because I like to help people learn programming and stuff, I have setup a few yahoo groups where people can learn from me/eachother, share files/programs, post messages, etc. - Trust me, I am among the best, so I think it would be very beneficial.

I am very willing to teach people everything I know whenever I have free time (I like to work on a one-to-one basis). Check out my groups if you are at all interested or curious.

Below are the web addresses for my groups (CAREFUL, I had to put a space after each slash, so if you copy and paste, delete the spaces):

I want to input/output high/low voltages through the cable. When using a multimeter:
pos. on red, neg on copper: 5.6 V, no current but stops cursor.

Any ideas for how to control the current and/or voltage? i.e. through transistors...

Anyone know the output voltage/amperage of the link port?

:-/

Why do you need to know?

I'm guessing the voltage is between 3 and 5 volts and the amperage is much less than one ampere (which depends on the load).

Hello!

First off, I think this site is fantastic! I'm new to this so I apologize if anything I say is a bit redundant or novice.

To the point, here is my idea:

I am in the process of assembling a statistic-based rock n roll band and I want to utilize my TI-83 calculator as the primary instrument. Basically, I want to compose graphs and have the TI-83, or my mac intrepreting the graph from the calculator, convert the data into sound.

i've already done a little research and know I need a TI-connect kit. As far as the program is concerned, I am bit lost.

Can anyone help me out? If so, you will definitely get a shout out in special thanks section of the cd booklet with your complimentary copy of "the normal curve".

Thank you!

ian.
aka the normal curve

Instead of doing all that graph stuff, get Omnicalc.
You can play music usig it. Refer to the owners manuel.

What are some good games for the 89 that have sound in them? I know I got one once but I can't remember which game it was.

i need an antenna to increase the range of the waves that the calculator outputs to am radio. anyone got any ideas or no what size resistor to use with a signal amplifier

Hey guys, I'm new, and I need to know one thing: how do you listen to sound generated from a calculator?

It's been mentioned probably many times already, but I'll add another so this answer is easier to find.

There are at least three good and easy ways to hear the sound:

1. Tune an AM radio to an unused frequency (no station). Hold the calc close to the radio antenna.

2. Buy a cheap (about 5 USD) 2.5mm to 3.5mm adaptor. Plug the adaptor into the calculator and any standard headphone into the adaptor.

3. Buy a cellphone or similar headset which has a 2.5mm jack. Just plug it into the calculator.

Keep in mind that the sound quality is quite low, so don't be surprised when you hear it.

I've already released this program
which is a guide on how convert any audio file into an 8xp file and play it using brandon sterner's Wav player 83+. I have noticed that this guide needs much updateing and i might actually venture out into the program sector.
I need someone who is good with writhing basic batch or cmd. (i know nothing about computer programing, only Calc basic) I need to run a program on every file in a folder and then output the result in another folder. If you are interested please download my program and look it over to see what it does. i really don't need to do the converting to wav anymore, most people can do that on their own. if you think you would be interested please e-mail me. (send me some form of contacting you besides e-mail, i can receiuve but not send.) Thanks!

ah yes, but if you only had one hand you'd be saying "it's not like I have TWO HANDS you know!", but you do, so there >:-Þ

Why is there not a program to convert midi files into Calcmod .z80 files. Would it not be similar to PolySnd MIDI Coverter
