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.

Risks and challenges
The risks of this project are low. We have already finished a lot of prototyping, material research and testing as well as already produced a small batch of pre-production units with our established suppliers. PCB's are already fully functional but might undergo another revision. The firmware will undergo further optimizing for minor usability and sound improvements. The enclosure has undergone several prototyping cycles already, we've tested a range of materials, gluing, folding and printing technologies. The side panels are already injection molded samples and just need a few slight adaptions.
Of course it can still happen that there are minor delays, because we can't foresee everything. Surprises lurk everywhere.
