Stringy (Project #14, June 2017)
In order to purchase items from our shop you need to be a
logged-in active member of the Boldport Club.
Stringy synthesizes guitar sounds using an efficient implementation of the Karplus–Strong string plucking synthesis algorithm inside of a tiny PIC microcontroller. It can play plays notes over five octaves (twelve notes in each octave) in either acoustic or electric guitar style.
Stringy is a remix of MadLab's 'Funky guitar' who also fully implemented the PIC's firmware.
You'll need speakers, a 9V battery and a piece of wire to act as a 'wand', in addition to the contents of the kit.
Assembly and much more information is available here.
This item will be shipped to you together with the next scheduled shipment, normally on the 15th of every month.
