MorseTweeter v.0.7 running

[LeseLaster]

Hello,

it took some time but finally the Arduino Uno is doing what he was supposed to do:

1. Go to Twitter
2. Look if there is a new tweet with the word "morse"
3. Get the tweet
4. Translate the tweet to morsecode
5. Give the morsecode as an acoustic signal

Now there are cw-signals in my room and I don't have to look at the computer screen. You find details in my blog:
http://hajos-kontrapunkte.blogspot.com/2011/01/morsetweeter-v-07-is-running.html

Of course the project is not finished. The parser for the  HTML-Code has to be optimized, ... The LCD-shield has to be connected and later the Arduino will controll a real morse keyer. Then the code will be published. Stay tuned!

What a great idea! 

Post a video when it's all up and running

Of course I will do that, but have just a bit of patience. I still need some time

Where's that *checking my watch* smiley?!

Great! Waiting for videos!

Just in case you want to see how I did my Morse code encoder and decoder, here is a link. You can simply call MorseOut(string)

raron has also created Morse code programs. Very nice, and high speed exchange between two computers. It's on the old forum.

That is really a good one. Will try it out. And as it is not only pure Arduino but also ham related, I posted it in a forum from the QRP-Club http://www.qrpforum.de/index.php?page=Thread&postID=48689#post48689 (QRP = Low Power Communication < 5 Watts Output.)

One thing I really don't like is your morse keyer  You should have invested a little more http://www.dl0bn.de/schurr/museum.htm

Have fun

Nice morsetweet thing!

I just thought (since someone said A... btw thanks for mentioning me liudr ) I would add my blog post link for that one as well, just in case.

And its google code page: http://code.google.com/p/morse-endecoder/

LeseLaster, thanks for posting my blog to a ham forum. I am completely open to suggestions for improvement. I agree with you. My keyer was not the best. Originally I made it as an impact switch so if a steel ball dropped on top of it, it will trigger the switch. With an electromagnet, it will record the fall time of a ball in air and calculate gravitational acceleration. The thing as a keyer completely sucks, having a spring that is too weak and slides sideways if you press it.

Anywhere we can buy a real but cheap keyer?

raron, are you a physicist too (somehow I have a hunch)? We should both buy some real keyers.

[LeseLaster]

Slightly OT, but anyway.

I would propose a morse paddle. One paddle is for dots, the other for dahs. So it is easy to connect to the Arduino and you don't have to measure time ratios between dits/dahs. If you really want to learn morse code and use it you have to invest a little bit more for at higher speeds good mechanic is crucial.

Have a look at http://www.eham.net/reviews/products/16 A reasonable priced paddle is from MFJ http://www.mfjenterprises.com/Product.php?productid=MFJ-564 or try some homebrew http://www.qth.at/dm3da/collection/.

Hope this helps

Have fun DL1SDZ aka LeseLaster

(Also slightly, well, rather OT, hope its okay)

Alas no, I'm not (yet?) But I would say it is in my field of interests

MorseTweeter is impoving to version v.0.8. I received the LCD-shield and had to struggle with the output. But now it is solved (see discussion http://arduino.cc/forum/index.php/topic,50596.0.html).

Now I have to improve the html-parser, so that only the twitter-strings are send to the Arduino. I have to get rid of things like that:

Code: [Select]

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.1//EN" "http://www.w3.org/TR/xhtml11/DTD/xhtml11.dtd">
<html xmlns="http://www.w3.org/1999/xhtml" xml:lang="de">
<head>

But it is manageable ... hope so  :~

hey, pictures and videos please! Don't keep your sweet success to yourself, at least not on this exhibition board  XD XD XD

Congrats!

[LeseLaster]

OK,ok.

Have a look in my blog http://hajos-kontrapunkte.blogspot.com/2011/02/morsetweeter-v-08.html. But please bare in mind that this is my first video ever and it is only a demonstration of the rolling LCD-shield - Ethernet is temporarily unavailable Error 401 

[liuzengqiang]

Nice, just saw it from a different post where you were asking LCD questions. I'll be updating my Phi-1 shield design soon and this time I'll take specific care that it is compatible with Arduino ethernet shield.

MorseTweeter v 0.9 is running, but I think that this is the end of the project. The software is running, but the parser to strip away all this code from the search.twitter answer is for me too hard to write.

Have a look at http://hajos-kontrapunkte.blogspot.com/2011/02/morsetweeter-v-09-and-perhaps-end.html

You will also find the "useless" code there. Have fun and thanks for the great help form the forum.

Now it's time for the next project, which will be a bigger success
