Related to this question, I need a means to display information on various displays placed around the room. Each display has different information. Ideally, I would have one laptop setup in a corner running a BASH script that coordinates everything (I'm familiar enough with BASH to handle this aspect). It sends out information that can be displayed on specific screens:
echo "Good morning!" > /dev/screen1
echo "Please stack the blocks as high as you can!" > /dev/screen2
echo "Fill out form B, then proceed to station 4." > /dev/screen3
echo "Your shift ends in 5 minutes. Please wrap-up your current task." > /dev/screen4
If possible, if images could be sent out, I'd generate them in the script using ImageMagick before being sent out just to make the text more pretty; if not, live updates of text on screen is well and sufficient.. Even running those machines in console mode only would be good enough a solution!
The ten laptops running Linux would display the information to visitors in the room; there is no need for anyone to interact with these devices, they'd be locked for viewing only.
Much thanks to those who helped answer my original question, but my situation changed a bit:
- I was unable to obtain permission to setup a Web server...
- ...but very, very surprisingly, was permitted to wipe the 10 computers and put Debian on each!
Basically I have my own personal laptop running Debian to run the BASH script, plus 10 laptops used as displays also running Debian, and if needed, they can all connect to Wifi...or I can buy long USB cables or Ethernet cables or whatever is needed to communicate between devices.
What is needed to create such a setup, given Web servers are no longer an option, but I'd have full control over the OSes on the 10 devices?
