It's a little late for Halloween [View:/resized-image/__size/16x16/__key/commentfiles/f7d226abd59f475c9d224a79e3f0ec07-96269e9f-897b-45c4-99da-4c7c9e4fc28e/contentimage_5F00_2516.png:16:16], but my board is now ready for next year! Drew and Bonnie, thank you very much for all the work you put into this and for helping many of us bring our work to fruition. This is the first project like this that I have tackled in, um..., 50 years. Having it work was extremely gratifiying and should open me up to new hardware projects.

Merry Christmas to all,

Ralph

I'll experiment with the different audio files and amixer later. I want to look a the code now to see if the blinking and duration can easily be randomized, to resemble more of a candle flicker, and maye even break it up ino four sets of lights.

Next year, we will have one that also blinks with the sound too.

Regardless, this was a great start. Thanks again!

It looks the same as yours...

Are your speakers working?

Well, my soldering skills are suspect ;-), and I've not been able to blink a light yet. Guess the two us need to put our Pi's in the same pumpkin...I have sound and no lights, and you have lights and no sound...

I'm able to blink the lights, but it appears that I am not able to play wav files with mplayer.

I've tried restarting alsa-utils, and also tried a new image.

These errors stood out:

mplayer: could not connect to socket

mplayer: No such file or directory

...

AO: [pulse] Init failed: Connection refused

Failed to initialize audio driver 'pulse'

The results from the recomended test:

pi@raspberrypi ~/files $ mplayer howl.wav

mplayer: could not connect to socket

mplayer: No such file or directory

Any recommendations would be appreciated.

I am running an August 2012 Raspbian image. When I went to install the software for this, I found that when I got to the step to install "RPi.GPIO" the compile failed (couldn't find Python.h). I'm not that familiar with the Python environment or Debian, but I was able to find a solution pretty quickly. I installed python-dev (sudo apt-get install python-dev). Then, repeating "sudo apt-get install RPi.GPIO" ran cleanly. Maybe this will help someone else...

My software runs fine now and I can play the sounds. Just have to get out a soldering iron tomorrow and see if I can do the hard stuff ;-)
