the problem
Most musicians take way too many pedals to gigs.

We will design a programmable effects box that will allow the musician greater flexibility and less baggage.

The Problem
goals
Goals
  • CD Quality Audio
  • Real Time Processing
  • Bitchin’ Effects
  • User Selectable/Programmable

via USB/PC interface

technical objectives stage 1 hardware
Technical ObjectivesStage 1 Hardware
  • DSP from Analog Devices: ADSP-21261
  • Codec from Analog Devices: AD1836
  • 2 inputs: RCA and ¼” TRS
  • 3 outputs: RCA, ¼” TRS, and

3.5 mm Headphone Jack

  • Memory for temporary sample storage
technical objectives stage 2 software
Technical ObjectivesStage 2 Software
  • Software is composed of two major parts
    • Loader/OS
    • Effects/Main Program
  • Main Program -> three tasks
    • Receive Samples
    • Process Samples
    • Transmit Samples
technical objectives stage 3 packaging
Technical ObjectivesStage 3Packaging
  • Make the device attractive
  • Make the device robust
  • External buttons for user control
  • LCD for interface feedback
  • Built in window
  • Illuminated circuitry
competition
Competition
  • Similar devices cost $100-$200 on average
  • Some are much higher
  • None are truly programmable
  • Some devices only produce a single effect
  • The “Butt Probe” retails for $549…
estimated cost
Estimated Cost
  • Our initial estimate for parts: little over $100.
  • Analog Devices has donated a development board that we will use as a model as well as a software development platform.
