My Current Project

Yes, I am still working on MARVIN, but for the last few weeks I have been spending some time on a really neat project.  It is an Microsoft Excel spreadsheet that converts old RTTTL ringtones into a language that the NXT can read.  I have converted about 100 songs so far, and I keep tweeking it to make it work better.  Right now it converts to RobotC and NXC.  I hope to add more languages soon.

Here is a screenshot of the file.

Ringtone Converter for RobotC

If you like to play music on your NXT, if you use RobotC and have access to Microsoft Excel, have I got a deal for you!

I have created an Excel spreadsheet that will very easily convert RTTTL (Ring Tone Text Transfer Language) ringtones into RobotC code with very little effort. RTTTL ringtones are the original ringtones that were just beeps and tones.

The Excel file contains over 300 ringtones ready to convert just by selecting which one you want and then putting the code into your file. You can also add your own ringtones that you may already have or have found on the ‘net. I have found thousands of free ringtones. It will only work with RTTTL format files and RobotC.

Some of the files need considerable tempo adjusting to sound right, so I have added a way to adjust the tempo of the music.

Here is a sample of the output of the file: (yes, this code works, try it out!)

I don’t have a site for downloading, so all you’ll have to do is send me an email at Tinkernology_at_yahoo_dot_com requesting the converter and I will reply with the Excel file along with a RobotC file I created with 42 songs already converted and ready to play for your use. That’s almost 10 minutes of music ready to play.

And if you are an Excel Junkie like me, you will enjoy tearing this file apart. I spent many hours working on it.

Rock On!
