Morse display for Twitter Streams
This project uses a Raspberry Pi and an Arduino or Shrimp to monitor tweets and display them as Morse Code.
The Pi requires py-serial and twython.
Install the Python script in a directory of your choice.
You will also need credentials(an application key and secret) to search twitter, which you can obtain from the twitter dev site
The Python code uses Oauth2; once you have an application key and secret, create a file called twitter.ini in a (new) sub-directory called secrets.
The file should look like this:
# key and secret for using twitter API KEY=your application key here SECRET=your secret here
You will also need to install morse_complete.ino on the Shrimp or Arduino.
The Shrimp's CP2012 should be connected to a USB port on the Pi.
An Arduino should be connected to the Pi via a standard USB cable.
You may need to change the port used by the Arduino interface, depending on the hardware and Operating System you are using.
I have had limited success using the Shrimp's CP2012 with recent versions of OS/X. If you are a Mac user you may prefer to use an Arduino.
I've made a couple of blog posts about this project.
