# Idea - Music Library and Radio Player (Logitech Media Server Client) - Synchronize multiple players at the same time - Direct control on the device (Touchscreen and Volume Controller) - Power supply can be disconnected without damage (the microSD in Raspberry is not ideal for 24/7 operation as a "hard disk") - Clean, closed housing with power socket - Speakers should be able to be chosen arbitrarily (3.5mm Audiojack) - Integration into Smart Home must be possible - Energy-saving # Components - Raspberry Pi Model 2 - 3.5 inch Waveshare Display (not HDMI but via SPI BUS) - "Rotary encoder" for Volume Controller - microSD - Minimum 2.5 A power supply - Small materials such as cables, sockets etc. # OS / Software PiCorePlayer with a Real-Time Kernel is used as the OS. This OS runs completely in RAM, which means that the microSD card is only used during booting. The advantage of this is the speed of the system (the microSD is a bottleneck on the Raspberry Pi) and that the device can be removed without damaging the microSD card or the system. On the PiCorePlayer, the software Squeezelite is already pre-installed, which is needed to communicate with the Logitech Media Server. Furthermore, the CPU has been "underclocked" and a fixed clock rate has been set (ARM processors regulate the clock rate according to demand in normal operation, but this is not ideal for this application). This article greatly simplifies the display setup, but cannot be taken over step by step. # PiCore button-tool install pcp bu cd /mnt/mmcblk0p2/tce/optional wget http://downloads.sourceforge.net/project/picoreplayer/beta/sbpd.tcz echo "sbpd.tcz" >> /mnt/mmcblk0p2/tce/onboot.lst pcp rb // Insert in WebUI under System start (GPIO PIN 6 and 12 is used here) /usr/local/sbin/sbpd -d -s e,6,12,VOLM
