[K3PZN-List] CCARC Raspberry Pi Group Gathering

[Peter Morton]

Pat-

Your emails made me recall a Raspberry Pi that was given to me three or 
four years ago by my son.  I searched my cluttered basement and finally 
found it, a Pi 1 B with the slower processor and only two USB ports.  I 
fired it up and determined it was loaded with an old Debian OS release.  
I downloaded Noobs and Jessie, saved the old OS to my PC, erased the SD 
card and copied Noobs with Jessie to the old SD card, but couldn't 
install it because the installation process required more free memory 
than my 4GB SD card had remaining.  So, made a quick trip to Staples and 
came home with a 16 GB SD card (8 GB would have sufficed) and finally 
got Jessie up and running.

I read that the new PI 2 is much faster, has two more USB ports and has 
more memory, so I ordered a kit from Amazon containing the Pi2 and 
accessories including a Wi-Fi adapter and a break-out board and cable, 
and now have it up and running with Jessie installed.

So, now I'm wondering, "What next?"  Where do you plan to go from here?  
What type of applications are planned?  Any ham radio applications in 
mind?  Are people interested in using the GPIO inputs/outputs?   Writing 
C or Python programs?  Learning the Linux commands?

I guess this will all be discussed tomorrow night.  See you there with 
my Pi.

p.s.:  This reminds me of Rich Mitchell leading a group in the club to 
explore the Arduino several years ago.  I still have my Arduino project 
up and running.  It was a dual synthesizer box containing two r.f. 
synthesizers controlled by an Arduino board and my (and Rich's) 
software.  I now have in mind an interface between a PC running N1MM+ 
and MMTTY and a transceiver.  The interface will accept data from the PC 
and provide accurate CW and FSK keying and PTT to the transceiver.  This 
project may require more detail work than my old brain can handle right 
now but it will be interesting if I can learn enough about using a 
Raspberry Pi to see if it could do the task.
