Hacking Bus Displays
Background
City of Oulu / Oulun Energia is dumping old bus displays and we got two of those. We promised to do our best to build something from them.
Devices
- Both are designed for outdoor public use, so they are heavy, metal enclosed, robust boxes.
- One is larger (1m x 1m) one sided, two 'modules' stacked vertically. Heavy.
- Second one is smaller two sided, two 'modules' back-to-back. Surprisingly heavier.
Mass media and modem (they used to communicate through 3G) were removed before we got them. Modem was apparently attached to the main card through ethernet. Device shows the IP on display upon boot.
Plans
- Figure out how they work
- Use at least one (larger) as information display. (Twitter? IRC?)
- Smaller ones for some project.
Generic technical info
- Telnet
- FTP
- Web-server
Linux (none) 2.4.17_mvl21-rpxlite #8 Fri Jan 16 16:59:00 EET 2004 ppc unknown
Posting content
It seems that you can POST information to WEB-server and it will be show at display. E.g.
Using curl: curl -d @display_request.xml http://10.2.0.139:8080
- display_request.xml
<?xml version="1.0" encoding="UTF-8"?> <displayMLRequest xmlns="http://www.peek.se/DisplayML/" version="1.12" dateTime="2001-12-17T09:30:47-05:00"> <setDisplay template="TimeOutTemplate"> <textField region="Top" align="center" valign="middle">Tarlab FTW!</textField> </setDisplay> </displayMLRequest>
