Advanced users can implement new hardware devices in Rattlesnake.\n\n### Capable\n\nRattlesnake has been run with over 50 control channels and 12 shaker drives while streaming over 250 channels to disk.\n\n### Research Focus\n\nTo facilitate MIMO vibration research and development, users can program their own control laws to load into the controller at runtime.\nSee [Control Laws](https://github.com/sandialabs/rattlesnake-vibration-controller/tree/main/control_laws) for examples.\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fsandialabs%2Frattlesnake-vibration-controller","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fsandialabs%2Frattlesnake-vibration-controller","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fsandialabs%2Frattlesnake-vibration-controller/lists"}
