You can keep track of the items you have, the ones that are running out and the ones that are already empty. You can print out an overview of the stocks or a list of items that are already out of stock. If you're on the go, you can VPN into your home network and check which item and how many of them are still in stock. I'll try to keep the setup costs as low as possible, so it'll be a system everyone can build. -I have to admit, that it got more expensive than i thought.

Documentation of the problems with solutions

Running JavaFX with Maven

The first small problem was to get JavaFX running with Maven. Since i wanted to use the Logging-Framework Log4J, Maven was pretty easy to use and a good choice.

+Problem: Deploying JavaFX as .jar to be executed via the commandline
Solution: Using the "JavaFX Maven Plugin" from https://github.com/javafx-maven-plugin/javafx-maven-plugin and building the .jar file on a PC/MAC/Linux computer


Running the JavaFX .jar on PI

Starting a JavaFX Application on a RaspberryPi isn't that easy, since Oracle removed JFX from their ARM install.
-Problem: Installing Java ARM and getting JavaFX seperately
+Problem: Installing Java ARM and getting JavaFX separately
Solution: Installing the latest Oracle Java ARM version, removing all the other Java installations (making sure the now installed one is used). Downloading the "JavaFX Embedded SDK" here: http://gluonhq.com/labs/javafxports/downloads/ and extracting the parts in the corresponding folders of the oracle Java version.

PI is not using the right Resolution of your Display

If you realize, that your JavaFX Application is smaller and squished you should change the hdmi settings of the PI
+

If you realize, that your JavaFX Application is smaller and squished you should change the HDMI settings of the PI
Problem: The displayed resolution is smaller than the actual resolution your display is capable of
Solution: Take a look at https://www.raspberrypi.org/documentation/configuration/config-txt.md on how to change the displayed resolution. For me the solution was to change the hdmi_group -> 2 (since it's a monitor and not a TV) and then you just have to search the right resolution in the hdmi_mode table. For me it was hdmi_mode -> 16
