papywizard User Guide

This documentation refers to the release 0.9.1

Installation

papywizard is entirely written in python, and uses some third-party modules:

• ​PyGTK -- GTK+ for Python
• ​pySerial -- serial bus access for python
• ​pybluez -- bluetooth python wrapper
• ​Visual Python -- 3D Python project (optional)

Linux

As most distributions come with python and all needed modules (just install them through your application manager), there is no need to pre-build a package. Just install it with distutils tools:

$ python setup.py install --prefix=/usr/local

Nokia

As Nokia is based on Linux, it is possible to install papywizard through distutils tools (see previous section). However, it is easier to install the debian package, through the maemo application manager. Add this repository entry in the application manager:

Name	gbiloba.org
Address	http://www.gbiloba.org/debs
Distribution	bora
Component	free

You also need the python repository:

Name	Maemo extra
Address	http://repository.maemo.org/extras
Distribution	bora (770/N800) or chinook (N810)
Component	free non-free

Note 1: on the 770, you need to install OS-2007 HE firmeware, in order to run python2.5. Then, you have to manually install python2.5-runtime package with dpkg (from x-term) before installing papywizard.

Note 2: on N800 and N810, you first need to install maemo-python-device-env package, from the application manager, before installing papywizard.

Configuration

No external configuration is needed; all parameters can be modified from papywizard config. menu.

Usage overview

papywizard is very easy to use, and I hope the GUI is intuitive enough.

The first thing to do is to edit the configuration, to reflect you camera/lens/head/hardware config.

Second, you need to connect to the hardware (Menu Hardware > Connect). If you use the bluetooth driver (default config), you need to enter the correct address of your adapter in the config menu (see above).

Then, just move the head either by opening the Manual move dialog, or using the shortcuts (see below), and set the start/end positions. As an alternative, you can automatically set the yaw to 360° and/or the pitch to 180°.

Once it is done, just open the shooting dialog and launch the entire process. That's it!
