What

SlabPi is the replacement for Slab on a Raspberry Pi 3. It has been moved, because of downscaling.

It runs the MPD Server and espeak. It is running on Raspbian Stretch Lite with berryboot.

A DAC+ Hat has been added for better audio quality.

RAM increased with zram.

espeak

Espeak is now functional, there were ALSA problems.

Motion webcam

Running motion for webcam, see this link

Possible resolutions:

  • 160x120
  • 320x240
  • 640x480

Can be checked with:

v4l2-ctl --list-formats-ext

The thing is not stable, and sometimes the /dev/video0 changes in /dev/video1 are something. Weird shit :p It is included in the Home Assistant view of Jarvis.

MPD

Fixed an issue where MPD hangs on song change. Fix it by uncommenting "device" option in the "audio_output" block (in my case ALSA) in mpd.conf. This is a common error.

Connection through client.

Host: slabpi.dhcp.nurd.space

Port: 6600

DAC+

PiFi HIFI DAC+ Digital Audio Card added for better audio quality.

Installation:
