We are going to use solenoids to apply pressure to these spots on the neck of the guitar.Hardware OverviewHardware OverviewUser InterfaceMicroprocessorRAMROMMIDI Decoder(Optional)FPGAMotor and Solenoid ControllersPick MotorsSolenoidsFlash CardSoftware OverviewSoftware OverviewUser InterfaceOperatingSystemMIDI DecoderFlash DriverMIDIs to RAMUser InterfaceUser InterfaceOur design will incorporate a user interface so that songs can be played by the user much like a typical CD player.

A solenoid will be picked basedon its size and power characteristics.The end of each solenoid will be padded in order to prevent damage to the guitar.Stepper MotorsStepper MotorsStepper motors will be used to strum the six strings on the guitar. The stepper motor used will be pick based on its size, price, and power specifications.Possible ExtensionsPossible ExtensionsAdd more frets to designElaborate on user interfaceExpand on string plucking timingAdd more frets to designElaborate on user interfaceExpand on string plucking timingDivision of LaborDivision of LaborRandyMicroprocessorUser InterfaceLucasFPGAMechanicsRickMIDI(Reading and Storage)DanMechanicsOverall AssemblyScheduleScheduleMilestonesMilestonesCDRResearch/Test ComponentsWorking mechanicsUnderstanding of Microprocessor architecture Milestone 1Implemented FPGA logicCompleted MIDI translator codeWorking motor and solenoid driversCDRResearch/Test ComponentsWorking mechanicsUnderstanding of Microprocessor architecture Milestone 1Implemented FPGA logicCompleted MIDI translator codeWorking motor and solenoid driversMilestones Cont.Milestones Cont.Milestone 2Combine Code and SubsystemsBegin testing, debugging, and optimizingExpoFull functional designCosmetics addedPossible design extensionsMilestone 2Combine Code and SubsystemsBegin testing, debugging, and optimizingExpoFull functional designCosmetics addedPossible design extensionsRisks/Contingency PlanRisks/Contingency PlanDifficulty programming MIDI decoderSolution: Use MIDI decoder chipProblems using flash card to transfer MIDIsSolution: Use serial cableStrength of solenoidsSolution: Explore other more expensive atternativesUser interface displaySolution: Use computer generated interface displayDifficulty programming MIDI decoderSolution: Use MIDI decoder chipProblems using flash card to transfer MIDIsSolution: Use serial cableStrength of solenoidsSolution: Explore other more expensive atternativesUser interface displaySolution: Use computer generated interface displayMarketabilityMarketabilityThe Player Guitar is the perfect product for the music lover who is unable to play the guitar, but loves the relaxing sound of an acoustic guitar. A great compliment to a player piano. Trying to start a band and missing a guitar player? No problem…. buy a Player Guitar.Any Questions?Any
