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.
Orchard Audio's ApplePi DAC is the most advanced and highest performance sound card hat for the Raspberry Pi.
The main goal of the project is to provide audio quality at a price point that is currently not available in the market. For less than $250 (ApplePi + Raspberry Pi) you can achieve performance currently only available at $750+ USD. In addition, ApplePi DAC eliminates the need for pre-amplifiers, saving even more money.
Over six months of development went into this project. Using only the highest quality and performance components available, the ApplePi DAC was designed from the ground up to offer commanding performance (see specifications below). Using the latest packaging technologies, ApplePi DAC became a reality. Performance was verified on a state of the art audio analyzer from Audio Precision.
The Audio Beatnik
"Ok, specs are great and all, but how did it really sound? Frankly, very good, surprisingly good." and "The mid-range and truthiness of the music rivaled that of the other DACs I have on hand that cost significantly more."
"Sound-stage and spatial resolution are just excellent."and "This DAC is producing the most detailed sound to ever come out of my Raspberry PI, all the subtle nuances of my test tracks were there and clearly distinguished from everything else."
Developing the ApplePi DAC is not cheap and requires a lot of time. All of the contributions will be directly re-invested in new products to expand the ApplePi family.
With the prototype units, the design has been fully tested and proven. Only some minor fine tuning is needed before moving to mass production. This includes tweaks to components and component placement to improve and streamline manufacturing.
Most of the risk is associated with setting up mass production. I am currently working with three different manufacturers and suppliers to get everything in order.
