What is a prototype?

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.

Functional Prototype

Demonstrates the functionality of the final product, but looks different.

Appearance Prototype

Looks like the final product, but is not functional.

Design Prototype

Appearance and function match the final product, but is made with different manufacturing methods.

Production Prototype

Appearance, function, and manufacturing methods match the final product.

We are bringing you the zero version of our wildly popular Audio Injector Raspberry Pi sound card. The sound card which is input capable, output capable and is ready for your to solder on an electret microphone - as simple as that.

Stretch goals achieved (you will get these) :

#1 at $4 500 : 2x RCA (red+white) RCA header for a breakout board. You can use it for inputs or outputs - you can attach it to one of the stereo headers - (not assembled)

#2 at $7 000 : 2x RCA (red+white) RCA header for a breakout board. You can use it for inputs or outputs - you can attach it to one of the stereo headers - (not assembled)

#3 at $9 500 : An electret microphone to fit the empty footprint (not assembled)

This includes everything you need to get yourself hooked up : The sound card, two IO boards, two cables, four headers and two RCA blocks.

Stretch goals to get (you could get these) :

#4 at $12 000 : We supply one potentiometer (not assembled)

#5 at $14 000 : We supply the second potentiometer (not assembled)

Specifications :

Direct Inputs : Unpopulated Connectors (stereo)

Direct Outputs : Unpopulated Connectors (stereo)

Potentiometer Inputs : Unpopulated Connectors and potentiometer (stereo)

Potentiometer Outputs : Unpopulated Connectors and potentiometer (stereo)

Headphone : Powered headphone connector (plenty loud). Populated

Microphone : Electret ready, just populate.

Sample rate : 96 kHz, 32 bit (with 24 bit ΔΣ DACs and ADCs)

Jitter control : Crystal locked, codec master, low jitter (Crystal on the card).

Hardware: Works with the Raspberry Pi2, Pi3 and Zero

We need your input

This is a unique live project where you get to have input on the live re-designs. We are up to design number 6 (with number 7 this week). We have changed from RCA headers to 3 pin 0.1 inch headers. Not only one, but the possibility of tapping off the input/output lines directly or after potentiometers for hardware volume control. We have also added a headphone header. Do you want something different ? Then please pledge and drop comments.

Risks and challenges

This is a low risk project. We have previously had two kickstarter projects and shipped those products on time. This sound card is based on the Audio Injector Pi sound card and is a very stable and popular product. We expect no surprises from this small form factor version of that sound card.

Part of our challenge is to meet the very small form factor, reduce noise and deliver the package which you want. We are asking you during the campaign to help us focus and redesign the input/output headers to find a product which is best to match your needs.
