A bunch of folks worked on getting the touch panels working. Then another bunch of folks wanted to setup some sort of crazy control Noisebridge in case of a fire thing with it, [[SCADA]]. The system that runs the touchpanel laptop by the door (172.30.0.31) is required for opengate-www and opengate scripts to work. It is connected by parallel port to a relay which is linked into the door buzzer system. All the touch panel machines use PXE boot and an image from a tftp server on [[Stallion]] to run. They require network access to stallion to come up. Currently the boot image for the panel starts up linux, runs Iceweasel full screen and points to a URL on [[Pony]]. There's a neat extensible interface that provides information and control regarding things we currently have in the space. There are 10x [http://www.parkytowers.me.uk/thin/Wyse3150SE/index.shtml Wyse 3150SE] thin clients available to drive the touch panels. The touch panels are made by iNexio and there is a custom XInput driver available for them in the source repository. The [[Inexio]] touch panels have their own wiki page with more info. == Troubleshooting == Symptom: mouse cursor on the touch panel is flying around without any touch input. Resolution: Remove power to the touch panel and disconnect any USB cables, then plug the touch panel and USB cables back in. ==Requirements== ===Fundamentals=== * Setup a system where anyone can create apps and content for this system. * "Don't suggest it and walk away, implement it instead!" ===Back end=== * Apache! Web apps! ** Everyone can write web pages! ===Functionality=== * You touch the touch panel and it clicks * You drag on the touch panel and it moves the mouse * When the thing boots it brings up a browser full screen * After a time out the browser resets to a "main menu" of sorts ** Includes current time * After a time out the box brings up some sort of interesting screen saver * The browser is killed and restarted once every 3 hours to help with getting stuck in a weird state ** Possibly displaying the current time * When navigating away from the main menu, there's a "home bar" at top ** Link to the menu ** Title of the current page ** Current time ===Application=== * Open the gate * Control X10 lights * Simplistic jukebox ** Currently playing on the main menu * Control the mediacenter * A "internet browser" interface ===Information=== * Local restaurants and menus for each * Bus times * Bart Times * Listing of events at Noisebridge, or the new scheduler * Weather ** With some info on the main menu * Watch a hacker space, links to web cams for other spaces ==Bugs== * Scroll bars are going to be tricky * Navigating to pages outside of the panel site might lead to the browser getting into a weird state. The dumb fix is to kill and restart the browser session every once in a while (3 hours sounds good). ==Installed Plugins== * Refresh2 * autohide * Grab and Drag ==Jukebox interfaces== * http://theory.steelbreeze.org/ * http://www.renedegroot.nl/mpd.xml * http://manatlan.infogami.com/wymypy * http://sites.google.com/site/cseickel/mpdwebamp * http://code.google.com/p/fookebox/ * http://cims.nyu.edu/~stucchio/software/djpirate/index.html * http://sourceforge.net/projects/mmpd/ =Build Procedures= The netboot environment is just debian-live. If you don't read [http://live.debian.net/manual/en/html/index.html the manual] you're likely to break something by accident. It's better to do development on your local machine using qemu and a copy of the config tree before executing the procedure below to push it out. * Log into stallion and make the changes you want to the files in /netboot/config as root. * cd /netboot/config * rm -rf binary* cache chroot * sudo lh_build --force * Back up the contents of /srv/debian-live * '''Test your image''', see the manual for how to set up a test environment. It's simpler than you think. * If everything worked, move /netboot/binary/* and /netboot/tftpboot to /srv/debian-live * Reboot one of the lesser used netboot machines and do a sanity check, make sure your changes aren't causing the machines to run out of memory and invoke the OOM killer. * Reboot the rest of the machines if you're happy. * If nothing breaks after a while, do a hg commit in /netboot/config. == Testing the image == On stallion: qemu -net nic -net user,tftp=/netboot/tftpboot,bootfile=pxelinux.0,hostfwd=tcp::2223-:22 -curses -boot n On pony: sudo kvm -net nic -net tap -curses -boot n
