Practicing scales and chord-progressions with the ElektroCaster

“How cool would it be to have a guitar that displays music information right on the fret-board itself?” – A question that took me quite a built-effort to put me into the position to answer it. But now here I am: A proud owner of a guitar that features an illuminated fret-board.

I’m making a new version of the ElektroCaster and want to share some insights into the process. This post is about the new LEF (light emitting fretboard).

The MultEBow

“The EBow is a battery-powered electronic device for playing the electric guitar. The EBow uses a pickup – inductive string driver – feedback circuit, including a sensor coil, driver coil, and amplifier, to induce forced string vibrations. The EBow is monophonic, and drives one string at a time, producing a sound reminiscent of using a bow on the strings.” (Wikipedia)

Pythagoras of Samos was a man with many hobbys. I know him for his experiments with strings and their musical properties. Thats why I call this robotic string instrument “Pythagotron”.

It features:
-2 octaves of pitch range
-fast and precise intonation
-4 actuators for striking, muting, punshing, damping and shorten the string
-modular and parametric design (OpenScad)
-most parts are 3D-printed or easy to gather
-open source
