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.
About this project
NanoSound is a Raspberry Pi audio add-on board for audiophiles. While it works out of the box running volumio & kodi, it is designed to be fully customizable and configurable by taking advantage of Raspberry Pi.
In addition to being a high quality HIFI Audio DAC, it provides additional functions such as:
Skipping songs and Volume Controls using buttons and Infrared remote control
Turn On and Off your raspberry Pi (Even Remotely!!)
Displaying the status on the OLED screen (Pro version)
Note that the buttons of the infrared remote control with be fully labeled in the production version
Yes, it works out of the box with Volumio & Kodi. A pre-configured Volumio & Kodi image will be available for download. Just plug NanoSound onto the Raspberry Pi, assemble the included mounting screws, insert the SD card and it's done!
NanoSound is an audio add-on board designed to plug on top of Raspberry Pi 2 / 3 (which has 40-pin GPIO connector).
Texas Instruments TPS7A4700 Ultra Low Noise Voltage Regulator for supplying the DAC
Pi Power switch (using same design as our Pi Switch product)
6 GPIO buttons for Media Control
Infrared receiver and remote control
1.3" OLED display with multi-language support
It provides an all-in-one solution for audiophonics who want an affordable and high quality DAC with many convenience features.
Absolutely, NanoSound is fully customizable and programmable! we take full advantage of the Raspberry Pi’s open architecture.
The 6 buttons are simple GPIO buttons. Python source code will be provided to read button events.
The IR receiver and control is LIRC compatible. Lircd.conf will be provided to read button input.
The 1.3" OLED display is using i2c. The python display driver code is open sourced.
The onboard on/off switch uses the same design and software as our first kickstarter project. It has an attiny85 onboard and is open sourced.
Because NanoSound’s DAC uses the very common Texas Instruments PCM5122 DAC chip, it is compatible with many distributions (such as Openlibre, Raspbian) etc. Nanosound’s DAC uses the same driver as HifiBerry DAC+ .
NanoSound uses a high quality Texas Instruments PCM5122 DAC (Burr Brown 112/106-dB Audio Stereo DAC With 32-bit, 384-kHz). It is also accompanied by HIFI grade components from EVOX RIFA, WIMA and ELNA.
We have tested NanoSound with many hi-end hifi systems and headphone. The quality is really good and on par with audio player which cost a few hundred USD more.
We have done blind listening comparison with other DACs using same chipset. As far as we are hear, they all sound equally good!
Yes, 3D printed case will be available for optional add-on item and is undergoing development. The stl file will be downloadable for free for those who want to print their own case.
Rewards & Models:
NanoSound Basic (You can add the 1.3" OLED Display Later)
Not a techie? Dont worry, installation is very simple:
Risks and challenges
As you can see from the video and product demos, the prototype is pretty much working and completed state. Our engineering and development are very confident in delivering the product on time with satisfaction.
Possible Risks of delay:
- Unexpected manufacturing problems during initial production. We will ensure that they are found as early as possible to minimize delays
