Hardware

• PHAT DAC installieren - http://www.instructables.com/id/Multiroom-Client-With-Raspberry-Pi-ZERO-and-PHAT-D/?ALLSTEPS
• alternativ: PCM5102A installieren
  • Anschluss: https://www.raspberrypi.org/forums/viewtopic.php?t=57069#p1162299
  • kann mit Skript vom PHAT DAC aktiviert werden, sonst s. http://disq.us/p/1l7ux1s bzw. https://www.hifiberry.com/build/documentation/hifiberry-software-configuration/
• Lautstärke über IR regeln
  • JBL-Fernbedienung nach Musikraketen-Anleitung auslesen
  • PoC Fernsteuerung
  • Alternative: Lautstärkeregler direkt ansprechen mit Transistor als Schalter (http://www.elektronik-kompendium.de/sites/slt/0208031.htm)

CNY70

• https://www.youtube.com/watch?v=KLkNqmqXVtA - Fehler in der Schaltungsskizze! Muss NPN- statt PNP-Transistor sein.
• http://www.vishay.com/docs/83751/cny70.pdf
• Achtung: Beim Vishay CNY70 ist im Vergleich zum Temic der Transistor um 180° gedreht! (s. Kommentar bei http://www.strippenstrolch.de/1-2-12-der-reflexkoppler-cny70.html)

Einrichtung

• SD Card read only: "Raspberry in Blue", c't 21/2016, S. 152
  • Update unter https://www.heise.de/ct/ausgabe/2016-21-Den-Raspi-als-Bluetooth-Empfaenger-einsetzen-3330683.html In der Befehlsfolge auf Seite 154 fehlt in der ersten Zeile ein Leerzeichen. Der Befehl zum Löschen der Dateien lautet korrekt: sudo rm -rf /var/lib/dhcp/ /var/spool /var/lock /etc/resolv.conf
  • Falls Sie das Dateisystem doch nochmal ändern oder Updates einspielen wollen, können Sie es mit "sudo mount -o rw,remount /" und "sudo mount -o rw,remount /boot" wieder temporär beschreibbar machen.

Scripting

• Bugfix
• Interrupts statt busy waiting: http://raspi.tv/2013/how-to-use-interrupts-with-python-on-the-raspberry-pi-and-rpi-gpio-part-3
• run statt call https://docs.python.org/3/library/subprocess.html

Gehäuse

• Buttons per Acryl-Transfer beschriften? ch.16.05.110-115.pdf
• Beim Zusammenbau Kamera vor dem Verkleben testen

Sonstiges

• Backup SD Card sudo dd if=/dev/mmcblk0 of=/media/tilman/ROT/raspberry-pi-zero_before-read-only.img bs=4M
• Passwort ändern und aufkleben
