NERP tonight! Eric Stein: RPi hardware i/o and ZeroMQ

ERP is not exclusively raspberry pi, the small computer and embedded control interest group at Pumping Station:One in Chicago.

Tonight, Eric Stein, who is Chief Cat Herder and president of Pumping Station:One will take time out of his busy schedule to show us a Raspberry Pi and Python based system that sends messages by passing messages.

Eric’s system, which is currently in development, receives input from IRC (internet relay chat) and responds by playing an informational message over one of several louudspeakers located around the PS:1 facility. The Pi does text-to-speech conversion on stored messages and i/o logic and control to select the appropriate audio output channel.

A very interesting aspect of the system is the use of ZeroMQ to pass control messages between the Pi and and a server that does something important that Eric will explain. From wikipedia:

“ØMQ (also spelled ZeroMQ, 0MQ or ZMQ) is a high-performance asynchronous messaging library aimed at use in scalable distributed or concurrent applications. It provides a message queue, but unlike message-oriented middleware, a ØMQ system can run without a dedicated message broker. The library is designed to have a familiar socket-style API.”
