[GreenKeys] Old Dog with some New Tricks.

[John Spigel]

I've added some photos of one of my TTY projects I mentioned a while 
back for generating TTY FSK audio using a Raspberry Pi, They are near 
the bottom of the page here:

You use the 3 position 'coded' toggle switches to select the source or 
file and then cycle power to reboot. The stream will start automagically 
in a minute or so. For better audio you may use a usb-audio adapter 
cord. You don't need a screen. But can attach a screen, KB and mouse for 
editing if you like. I use Putty and Winscp remotely from a laptop. This 
is my first python project so just getting my feet wet.

Here are examples of the shell scripts called from the python code.
You can use these alone or with the gpiotty27.py code.

All for fun and to share and demo some of this heavy iron. Can't get enough.
