A small wxpython application to control a video projector via ethernet.
I need this to control the shutter of a panasonic video projector during a theater performance. The projector has a built-in web interface and no other way of controlling it via ethernet, A web interface is quite clunky for this purpose, Further, the shutter shall be opened and closed from the video playback program, which can emit keypresses, midi messages and much more, but is unable to navigate web interfaces.
Thus, what I need is a program that can be controlled by a system-wide hotkey, toggles the shutter upon triggering and provides a a small visual feedback window.
projectorControl is developed under Python 2.7. I don't know if I used something that needs this version, maybe you'll get lucky with 2.6 or 2.5.
It is tested with Windows 7 only. The application might run on other platforms, however, the hotkey feature will only function with Windows.
The following external dependencies exist:
- wxPython - the GUI framework
- PyPubSub - publish-subscribe-API
- My own "threadsafe" version of PyPubSub.pub.sendMessage()
- requests to make HTTP requests to the projector
- Beautiful Soup to parse HTM
A .spec-file for PyInstaller 2.0 is included, so you can easily build an .exe for Windows containing all of the dependencies.
Just run
python projectorControl.py
inside the src/projectorControl directory
or start the built .exe-file
projectorControl will parse a config-file named projector.ini that must be in
the same directory
as the .exe or the projectorControl.py script.
No problem, the projector "model" is completely decoupled from the GUI and the
control logic. Just have a look at projector_model.py as an example of how to
implement your own Projector class.
I'm using Turq as a mock HTTP server. The
file turq_rules.txt contains the configuration for Turq to respond like the
actual projector. You have to change the state of the mock projector manually,
by (un)commenting the appropriate line.
