pedalSHIELD Arduino Guitar Pedal.
pedalSHIELD is a programmable Arduino Open Source & Open Hardware guitar pedal made for guitarists, hackers and programmers. Users can program their own effects in C/C++ or download ready effects from the online library.

It is designed to be a platform to learn about digital signal processing, effects, synthesizers and experiment without deep knowledge in electronics or programming.









pedalSHIELD Hardware Design.

Specifications:

Based in Arduino Due.
Configurable sampling time from 8kHz to 192kHz.
More than 2200 instructions per sample at 48kHz
Microcontroller:
84MHz 32bit Atmel SAM3X8E ARM Cortex-M3.
96KB RAM, 512KB Flash Memory.
Integrated DMA.
12 bit ADC/DAC integrated sampling up to 1Msps.
Interface:
3 Configurable potentiometers.
2 Configurable switches.
Blue power-on led PWM controlled.
True Bypass Footswitch.
Connectors:
Input Jack, 1/4 inch unbalanced, Zin=10M?.
Output Jack, 1/4 inch unbalanced, Zout=1K?.
Power supply: power taken from Arduino Due board.
The design was created using KiCad, a open-source GNU free of charge electronic design CAD tool. All schematic native files and bill of materials are public. The circuit can be broken down into 5 simpler blocks: Power Supply, Input Stage, Output Stage, User Interface and Arduino Connectors:

Hardware Hacking a new musical instrument with an Arduino and an Electric Guitar
by Logan Poelman

How do you create a new type of musical instrument using the right sensors, arduinos and some clever ergonomic engineering?
I invented a way to play bass and guitar, at the same time,
using the same 4 fingers and thumb you normally use to play guitar,
on a regular old electric guitar.
(with a bunch of software and hardware and sensors)



Learn about analog to digital sampling, physical computing, MIDI, arduino, physical design, prototyping and more!
I will talk about the design issues, coding challenges, going from idea to POC to prototype to pilot.
Design of the pedal:








take a listen/look at:

initial POC:

improved the software: ! No longer available

Grew up building stuff with RadioShack parts and hacking junk I found in the garbage.
Built my first synthesizer when I was in 7th grade ( UJT Transistor oscillator design). Started programming on TRS80 + Apple II's in 1978
Started playing guitar in 1979
Started my programming career building Video Games in assembly language on the IBM PC & C64, in the late 80's.
(you can play "Ajax" at https://archive.org/details/msdos_Ajax_1989)
Worked on Wall Street for about 10 years building ginormous scale systems.
Former Adjunct Professor at NYU in the Computer Science graduate program.
Guitar player & musician
(my old band)

Inventor.
Noodler.
I've been hacking the Arduino since 2009.
Hacking the Raspberry Pi since 2012.
Over the years, I have programmed in: Ruby, JavaScript, Java, C#, VB.Net, VB, Forth, C++, C, Fortran, SNOBOL, Pascal, Basic
and Assembly (on 6 architectures - ARM,ATMEL AVR, 8086, 6502, Z80, PDP)
I have programmed CPUs, GPUs, DSPs, MCUs in Assembly, C and less soul crushing languages.


My day job: Director of Enterprise Technical Architecture for Best Buy, Co.
BTW, I'm hiring highly talented Technical Architects that can still write code -

The pedalShield Uno is an Arduino shield by ElectroSmash that turns your Arduino Uno board into a digital effects pedal for your guitar. The shield is sold as a kit that you can solder together yourself and the best part is that all of the hardware and software are open source.
