info-beamer-node for OSUE Exams

An info-beamer node from dividuum/info-beamer-nodes, modified for the OSUE exams @ TU Wien.

The subdirectory scripts contains startup scripts for the Raspberry Pi or Jetson TK boards connected to the displays of our labs, and a tool to generate the exam schedule for the nodes.

The info-beamer node is running during the OSUE exams to display student IDs w.r.t. slot, i.e., time and room. Tutors can use this info to log in the students. Further it shows how much time the students have left (per slot).

PLEASE NOTE: The software is based on other open source software, check the subdirectories for the LICENSE.

Configuration

See the README in the scripts folder how to configure the nodes for an exam.

Installation

Copy the node directory to the Raspberry Pi.

Install the startup scripts (e.g., add a cronjob).

Usage

Copy the python script send-command or clone this repo to the lab application server.

For example, start the first slot in lab room 4.

$ ssh <lab/osue/info-beamer-node>
$ ./send-command -r 4 reset
$ ./send-command -r 4 forward
$ ./send-command -r 4 start
