Morseus

Morse signals translator.

We believe in the importance of communication, especially when you're in great need and conventional channels are not available, but you can rely on one of the simplest (and fastest at the same time) information carriers, light. By this, we enable you the possibility of sending and receiving Morse light signals without even knowing the code, but just having the Morseus app installed on your portable device, without the need of an internet connection, GSM or any kind of access.

With Morseus you can decode Morse signals sent from humans in real-time, then talking with them in "their language" at the very same speed, all of these by just opening the app and pointing the camera towards the light source, even from far away. Write text, click Start and now you're replying in such a way that the sender will perfectly understand your message.

Installation

You can download prebuilt binary executables for your platform by accessing the links below:

• Mac, Linux, Windows: https://goo.gl/BUc9kx
• iOS, Android: App/Play Store

Manual install

If you want to manually install the app on your supported platform, then you need to download the repository, install the package alongside its requirements and finally run the app's main executable script.

For this project, we're gonna use Python 2 version and closely follow the instructions below. They are compatible with the Mac platform, but with minor changes you can make them work on Linux or Windows too.

Install Python interpreter and pip:

Mac

$ brew update && brew install python
$ easy_install --upgrade pip

Make sure that you're using the correct version of pip by running pip --version. It should use the Python 2 version, if not, try with pip2 instead.

Clone repository and install package:

$ git clone https://github.com/cmin764/morseus.git
$ cd morseus
$ ./setup.sh    # setup.bat on Windows (use `sudo` on Linux)

Note that Morseus relies on libmorse library which is installed automatically by pip using the requirements file. If this doesn't install as it should, please clone the repository and install the package by running ./setup.sh.

You'll also need to have Kivy fully and correctly installed, using a proper version of Cython. For doing that, we recommend uninstalling any previous version of kivy and installing the latest one with: pip install git+https://github.com/kivy/kivy.git@master, but first, just figure out what's the version you're installing and use the appropriate Cython described here. Depending on the actual configuration, you may be needing other dependencies as well, like OpenCV or GStreamer. For more information on installing kivy, please consult the following page.

Usage

Run the main executable

Mac

$ python main.py

That's it, it should work straight out of the box. Just grab your phone and tap on your lantern app (or a real lantern) or why not :), text into a Morseus mobile app, to send Morse light signals to the receiver menu presented to you, in order to see how the application is working.

You can switch afterwards to the Send menu in order to send your text message as light signals emitted by a black rectangle which is coloured into white for every dot or dash.

Custom Options are available for you in case you're not happy with the current configuration.

Remarks

The idea behind this software is to communicate in Morse code without any kind of required knowledge, calibration or beforehand configuration. It just works!

Development

You can be part of Morseus and bring your contributions into it by developing and solving the remaining issues and TODOs.

Optionally install virtualenv:

Mac

Put the following in your .bashrc, .bash_profile, .profile etc.

# Python virtualenv.
export WORKON_HOME=$HOME/Envs
export VIRTUALENVWRAPPER_PYTHON=/usr/local/bin/python
export PROJECT_HOME=$HOME/Repos
source /usr/local/bin/virtualenvwrapper.sh

If you go on with the .bashrc solution, then don't forget to add a source ~/.bashrc in your .bash_profile file.

$ pip install -U virtualenv virtualenvwrapper
$ source ~/.bash_profile
$ mkdir -p $WORKON_HOME
$ mkvirtualenv morseus

Use workon morseus command to activate the virtual environment every time you want to work through it and deactivate for leaving it.

Install requirements, develop and test:

Don't forget to uninstall the package first (if installed):

$ pip uninstall morseus

Then:

$ pip install -Ur requirements.txt
$ python setup.py develop
$ python -m unittest discover

Don't forget to run with sudo -H if you're working outside the virtualenv and using a linux environment.

Run tests, create and serve documentation:

$ nosetests
$ cd docs && make html
$ cd build/html && python -m SimpleHTTPServer

Enter http://localhost:8000 for viewing the documentation.
