Marabunta

Description

Open source parametric musical instrument model that can be tailored to any size

Details

This is a parametric stringed instrument generator that can create anything from a pocket ukelele to a triple bass. The instrument geometry is derived from a spreadsheet; variables such as number of strings and length of strings are produced from the geometrical skeleton file. The present functional version of marabunta is dependent on autodesk inventor; soon a version will be released that uses a python scrypt in Blender to create the model geometry.

The instrument is open source, and designed so that anyone can fabricate it with a CNC machine.

Digital functionality for creating MIDI/DMX will also be integrated for controlling the instrument with the teensy development platform.

also, from ye previous year, some of the FPGA functionality may be added.

"An orphan picture. Other than it is a spider wasp and came from the county I work in I don't know much more about this azure beauty. It was taken when we were first setting up the camera rig in 2012....so likely just fell between the cracks."

Worth noting that both the 3d printer and the camera were purchased with money from an earlier entry.

Marabunta is on hold until the Denver Maker Faire ends this weekend. I will be hosting two booths, the robot spider petting zoo and the levitating laser vaporizer in the Colorado Inventors Showcase. The spiders are closely related to Marabunta, running a custom linux OS that was designed to function as a universal audio workstation. If all goes well, the Marabunta instruments will soon be able to control a swarm of tap dancing robot spiders.
Naming Conventions

I tend to name my instruments after insects and spiders; When I started this project, I called it the hornet. It turns out that there is a hornet bass already on the market, even though there is no hornet guitar. As this system is designed to be capable of creating guitars, basses, mandolins, etc... It seemed worth it to change the name, and avoid the confusion of being the second electric bass called the hornet. Marabunta is a South American colloquialism for hornets that hunt spiders, and is an uncommon enough term that I was able to score the domain for marabunta.net.

underpants gnome scheme:

create documentation on how to fabricate AN instrument, then rebuild structural geometry
release geometry, and translate geometry to python/blender
collect prize
