Date/Pages: July 2006; 70 pages
Abstract: An economical and robust data logger is presented that is well suited to ballistic environments. This ballistic data recorder acquires two channels of analog data over a 0- to 5-V range, with acquisition times as short as 2.3 ?s and record lengths as large as 0.5 MB per channel. The microcontroller-based architecture allows many data acquisition parameters such as rate, mode, triggering method, and record length to be selected and varied by the user. Onboard batteries and charging circuitry further enhance the data logger?s applicability and flexibility. Complete details of the ballistic data logger?s hardware and software are presented in this report. A description of the hardware begins with a broad overview of the ballistic data logger?s capabilities and method of operation and increases in complexity to provide complete electronic schematics, fabrication methods, and component procurement information. A complete listing of data logger software is provided with extensive documentation. The ballistic data logger?s performance is verified with an example of acquired data.
