The Quiet Micro Boat [QMB] is an inexpensive acoustic sensing platform constructed from off-the-shelf hardware and software components to allow for a fleet of acoustic sensors that can be deployed into real-world sensing scenarios at a low cost. The QMBs operate using a Beaglebone Black as a central processor, with jet propulsion generated by bilge pumps for robust ocean operation. Acoustic data are collected through a hydrophone which interfaces with the BBB, and data is centralized using the XBee and Zigbee radio mesh configuration. The talk will focus on the hardware costs and performance, discuss the design cycle and decisions, and feature some of the acoustics projects that have been tested on the devices.
