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 (thinkpad) 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.
This laptop runs uses PXE boot and an image from a tftp server on [[Stallion]] to run{{verify}}.  It will not boot without network and this server on the remote system.


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.

=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
