• Kitchen Player update

    Matt Callow • 09/30/2015 at 00:50 • 0 comments

    Now with case!

    I've put the android phone into a small wooden case that I made on the laser cutter at RoboDino using the excellent tabbed box maker plugin for Inkscape

    Here's what's inside

    The phone is running:

    • Tasker
    • AutoSqueeze (tasker plugin)
    • SqueezePlayer
    • Headset Button Controller

    There are two buttons which are connected to the microphone input which allow control of the player.

    • Red button; single click = play/pause, double click = reset
    • Black button; single click = next track, double click = previous track

    Of course, it's also possible to control the player via any of the many Squeeze controller apps, or the web interface.

    Later I may look at exposing the screen to allow track info to be displayed. But for now, this is working great.

  • OpenELEC

    I tried the OpenELEC build from here http://www.horus.com/~hias/tmp/openelec-wolfson/5.0-rc-cirrus/

    This supports the cirrus audio card out of the box, which is great. I had no problems using this for a quick test of XMBC/Kodi

    But, It's not really what I'm after. It's a specialised distribution for Kodi. I'd rather use a more general purpose distro (so that I can modify it later)

  • Linux Images

    I tried a couple of Linux Images to see if they support the Cirrus Logic audio card.

    • Volumio 1.5 - does not support the audio card.

    Using Squeezelite, I can set up a simple squeezebox player

    Squeezelite v1.7, Copyright 2012-2015 Adrian Smith. See -t for license terms
    Modifying rc.local to run squeezelite at startup:
    pi@raspberrypi ~ $ cat /etc/rc.local 
#!/bin/sh -e
#
# rc.local
#
# This script is executed at the end of each multiuser runlevel.
# Make sure that the script will "exit 0" on success or any other
# value on error.
#
# In order to enable or disable this script just change the execution
# bits.
#
# By default this script does nothing.

# Print the IP address
_IP=$(hostname -I) || true
if [ "$_IP" ]; then
  printf "My IP address is %s\n" "$_IP"
fi

  • Lounge Player

    This one will be a connected to my Hi-Fi amp. It will be housed in a Reciva Internet Radio (https://radios.reciva.com/) case:

    but with the internals

    replaced with a Raspberry Pi Model A+, and a Cirrus Logic Audio card

    I'll use squeezelite (https://code.google.com/p/squeezelite/) as the player. First, I need to get the sound card working.

    I'm going to look at the piCorePlayer image(https://sites.google.com/site/picoreplayer/) to see if that supports the sound card (I expect it doesn't)

    Failing that, I'll try the 'official' cirrus_audio.img from Element14.

  • Kitchen Player

    Matt Callow • 01/08/2015 at 01:49 • 0 comments

    My player for the kitchen consists of an old HTC wildfire phone running SqueezePlayer and a pair of Altec Lansing amplified speakers. This has been working well for a week or so. Since I already had the phone and the speakers spare, the total cost so far is A$5.29.

    I'd like to add some local control buttons. I'm thinking of wiring up 3 buttons as per this article http://hackaday.com/2010/11/03/patching-into-android-music-control/ and then using Tasker and the autosqueeze plugin to control the player. I may also need Headset Droid to capture the button presses.
