## Hardware
- PHAT DAC installieren - http://www.instructables.com/id/Multiroom-Client-With-Raspberry-Pi-ZERO-and-PHAT-D/?ALLSTEPS
- 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 <prev>
- 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


## Google Drive
sudo mount -o rw,remount / && sudo mount -o rw,remount /boot
