I needed a status indicator for my Raspberry because my RPI server is running headless and I did not always want to access it from the outside.
So I ordered this cheap 0.96 OLED display (128x64) in China (the link to Ebay is below), and developed a case for it.

The wiring for this project is very simple (4 cables).

There are also many more scripts with which you can feed the display (no support on my part)!
see link: https://www.raspberrypi.org/forums/viewtopic.php?t=150342

Furthermore, this case is also available in a 30mm fan version, as well as a passive cooled version.
The goal behind this is to create a modular system for many applications, which can be expanded.

The next step will be a 2.5 "hard disk drive that can be operated with a cheap China USB to SATA converter (<$ 5). --> done

Leave me in the commentaries like your suggestions and ideas what extensions would be synonymous sill!

Have fun with it, and share your Makes ...

Ich benötigte für meinen Raspberry eine Statusanzeige, weil mein RPI-Server headless läuft und ich nicht immer von außen darauf zugreifen wollte.
Also habe ich mir in China dieses günstige 0.96 OLED Display (128x64) bestellt (den Link zu Ebay gibt es unten), und ein Gehäuse dafür entwickelt.

Die Verkabelung für dieses Projekt ist sehr einfach (4 Kabel).

Es gibt auch viele weitere Scripte mit denen ihr das Display füttern könnt (kein Support meinerseits)!
siehe link: https://www.raspberrypi.org/forums/viewtopic.php?t=150342

Des Weiteren ist dieses Gehäuse auch in einer 30mm Lüfter Version, sowie einer passiv gekühlten Version verfügbar.

Das Ziel dahinter ist ein modulares System für viele Einsatzmöglichkeiten zu schaffen, welches man erweitern kann.

Der nächste Schritt wird ein 2,5" Einschub für Festplatten werden, den man mit einem günstigen China USB zu SATA Konverter betreiben kann (<5$). --> erledigt

Hinterlasst mir in den Komentaren gerne Eure Anregungen und Ideen was für Erweiterungen noch sinvoll wären!

Viel Spass damit, und teilt Eure Makes...

Gruß SG

the wireing:

Display VCC --> RPI PIN1
Display Gnd --> RPI PIN14
Display SCL --> RPI PIN5
Display SDA --> RPI PIN3

fan(5v/0,2A/30mm):

fullspeed(5V): "red" wire fan --> RPI PIN2
or:
lowspeed(3,3V): "red" wire fan --> RPI PIN17

GND fan: "black" wire fan --> RPI PIN9

the software part:

ssh to your Raspberry and follow the next steps:

• sudo apt-get update && sudo apt-get upgrade -y (update at first)

• sudo raspi-config (go to interfacing options/klick i2c/enable --> yes)

• sudo apt-get install -y python-imaging python-smbus i2c-tools (install dependencies)

• i2cdetect -y 1 (detect the Display (in my case its "3c"))

• git clone https://github.com/adafruit/Adafruit_Python_SSD1306.git (install the Adafruit https://www.adafruit.com library to use their stats.py example for our display)

• cd Adafruit_Python_SSD1306 (go to the Adafruit folder)

• sudo python setup.py install (install)

• python stats.py (first try! it should work!?)

• sudo crontab -e (make it rebootable via crontab)

• Scroll to the bottom and add the following line:

@reboot /usr/bin/python /home/pi/Adafruit_Python_SSD1306/examples/stats.py

• save & exit

• You are done, everything should work now...

!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
if your 2,5" HDD wont't run, try:

• open a terminal and type: sudo nano /boot/config.txt
• and edit @ the bottom: max_usb_current=1
• sudo reboot

now it should run
!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
