I saw this at the London hackspace: A pillar with a bunch of computer displays showing all different sorts of things. So I thought: Let's build one for the lab as well! We have a whole bunch of monitors, let's make them do something cool.
Ideas
One SomefruitPi per Monitor
- Many Pis on a network
- Super cheap: OrangePi? [1]
- Problem: Most are VGA based, Pis only do HDMI
- HDMI VGA converter? Do they work?
One PC, many graphics cards
- Old PCI Multihead cards (e.g. nVidia Quadro NVS280)
Mounting
The displays need to be mounted somehow. Ideally, we would just get a ton of display arms. But they are expensive. Maybe we can just build them ourselves?
Software
- Displays should show a website, or run through multiple websites on sort of a schedule
- Centrally managed
- https://github.com/tiefpunkt/signman
- Currently uses Midori browser, because Chromium is not available on standard Armbian build for the OrangePi One, and Firefox doesn't support kiosk mode out of the box
Hardware
- OrangePi One
- Cheap HDMI->VGA Adapter
- OS: Armbian [2]
- Getting started: https://docs.armbian.com/User-Guide_Getting-Started/
- Initial login: root/1234
- Software runs well, just the VGA output is weird
Mounting
- We have some steel piping we'll mount to the wall
- Monitors will get a VESA-to-pipe-clamp mount, which attaches to the steel pipe
Setup
- Flash SD card with Desktop version of Armbian
- Boot up in CLI
- Login as root, PW 1234
- Create user "mumalab"
- Fix resolution to FullHD: h3disp -m 10
- Update packages
apt-get update apt-get upgrade
- Install browser
apt-get install midori
- Prepare mumalab User
su - mumalab wget https://raw.githubusercontent.com/tiefpunkt/signman/master/client/signman.sh chmod 755 signman.sh crontab -e > */5 * * * * /home/mumalab/signman.sh
- Reboot
- System will boot into graphical interface
reboot
