puredata class

This repo contains a short puredata class with some examples and a webserver. Use pandoc to generate the index.html in the source directory. The included webserver can be used to host the course on the LAN.

Dependencies:

• pandoc
• python3 bottle framework

It also includes a small OSC server that can be used to dispatch data to clients. This server fetches JSON data from online sources and formats it to OSC bundles. It currently dispatches:

• weather data
• bitcoin price data
• cpu and ram data

To run the server you need these python3 dependencies that can be installed with pip.

• python-osc
• psutil

The server listens on port 8080 and send OSC data back on port 8081 to the client who requested the data. The following OSC messages can be sent to the server.

/get/weather [CITY]
/get/bitcoin
/get/cpu

It's running as a systemd service with the following configuration at /etc/systemd/system/osc_server.service.
