For my most recent presentation I have set up my own Wifi using an old Fritz! Box flashed with Freeze that can route all incoming traffic towards a Macbook (that is connected to the router by cable).<\/p>\n

The presentation with all results is running in a Chrome full screen windows that is mirrored to the projector.

All scripts are available per email request.<\/p>\n\n
