This document describes the research, design, and testing of the speed gun designed by Group 2A for the School of ECEN 4024 Capstone Design class of spring 2017. The project was assigned at the beginning of the semester to be turned in after demonstrating its functionality at the end of the semester. The purpose of this project was to demonstrate the skills obtained through the School of Electrical and Computer Engineering curriculum in one project covering many areas of electrical and computer engineering. The specifications are set by the group, and the end design must match these specifications. In this report, the responsibility breakdown, budget and schedule, background information and research, methodology, detailed design, and end results are all described.The group was allotted 250bytheSchoolofElectricalandComputerEngineeringdepartmenttodesignandbuildafunctionalproject.Group2Abrokeaparttheworkloadbasedonskillsandcomfortabilityworkingwithcertainareasoftheoverallsystem.ThesesectionsincludedRFcircuitryforRoy,electronicscircuitryforTyler,softwaredevelopmentforMatheus,andpackagingdesignforAndrew.Eachmemberperformedtheirshareoftheworkaswellascontributedtotheothersectionsasneeded.Afterresearchingtherespectivesections,thegroupcametogethertodesignanoverallsystemtoperformatthespecifiedgoals.Aftermanychallenges,hardwork,andcollaboration,thegroupwasabletocompletetheprojectaheadofscheduleandreachsomeofthestretchgoalsfortheprojectincludingaPCBdesign,BLEimplementation,andmultimodeoperation.Thedevicemetthespecifications,successfullymeasuringthespeedofabaseball.Innormaloperation,thespeedgundoesnotexceedatotalcurrentdrawof120mA,consuming600mW.Thegroupstayedwellunderbudgetcominginatagrandtotalof162.64
