A prototype is a preliminary model of something. Projects that offer physical products need to show backers documentation of a working prototype. This gallery features photos, videos, and other visual documentation that will give backers a sense of what’s been accomplished so far and what’s left to do. Though the development process can vary for each project, these are the stages we typically see:
Proof of Concept
Explorations that test ideas and functionality.
Demonstrates the functionality of the final product, but looks different.
Looks like the final product, but is not functional.
Appearance and function match the final product, but is made with different manufacturing methods.
Appearance, function, and manufacturing methods match the final product.
Mozzie is Ozzie (Australian slang) for mosquito. We called our audio synth software Mozzi after being kept awake one night by mozzies buzzing in the tent while camping,
From our experience with many Mozzi projects since then, we have found that there is a basic set of audio components and connectors required in every project, and repeatedly building this basic platform is a pain.
So we designed the MozziByte hardware platform to support our Mozzi software.
MozziByte provides a digital audio amplifier, audio socket, speaker pins, battery connector, power switch and prototyping area for connecting sensors, knobs, and switches to an Arduino Pro Mini.
MozziByte amplifies your sonic creativity by providing an audio hardware platform that lets you focus on designing sound and interaction, rather than fiddling with breadboards and tangles of wires.
MozziByte allows designers, artists, musicians and students to rapidly prototype and create innovative and imaginative sonic products, sound art installations and custom synthesisers by providing the core audio components needed in every project.

Risks and challenges
We have tested a short run of ten SMD Assembly prototypes, and have identified the following risks and challenges.
We have established working relationships with two different manufacturers and have gained a good understanding of the process through three iterations of PCB design, prototyping and production.
We are experienced with finding alternative sources for parts when they unexpectedly go out of stock or become too expensive.
Defects and Delivery
We will order an additional 10% replacement Mozzibytes to cover manufacturing defects and postal delivery losses.
You are a user and Fan of the Mozzi sound synthesis software and would like to support the development of the MozziByte hardware platform that makes it much quicker and easier to bring Mozzi sketches to life in sonic objects, interfaces and installations :)
