Innovate with Pivotal RabbitMQ and Rasberry Pi | Pivotal P.O.V.

Adam Bloom from Pivotal has written a guide to installing and using RabbitMQ on a cluster of Raspberry Pis.

Here’s what they say about RabbitMQ:

With Pivotal RabbitMQ, we have a highly scalable, efficient, easy-to-deploy message queue. Beyond the long list of support for languages and protocols that could connect to a cluster of Pis running RabbitMQ or distribute messages to individual Pi subscribers, RabbitMQ also supports MQTT for when Pis are clients or sensors. With MQTT, any device on a network can send data directly to a message queue, and the protocol is ideally suited for sensors and mobile devices.

Foundation forum member ‘dozencrows’ has modified the ‘Motion’ software used for motion detection for the Raspberry Pi camera module. I’ve tried it myself and it works brilliantly and with only a couple of seconds lag.

Instructions on available on the Raspberry Pi Foundation Forum. If you have problems running it, read the rest of the thread as many of the common issues are covered there.
