Moto Mod Updates - Techy Stuffs
Moto Z is turning out to be an awesome platform, No More Rubberbands! No More Adapters!
I've finished the power supply design! Doesn't sound super exciting, but it is!
I have clean +/- 5 Volt rails. I am working on selecting DACs from a pool. I have it narrowed to two, for two separate models I am making.
One will be used for the simplicity and cost - PCM5142
The other will be used when I get more time to really look into high bitrates/depths - AKM4490EQ
The I2S audio is being provided by the development kits that Motorola put together, claims to be up to 192kHz/24Bits. The PCM5142 version will be running 96kHz and 16bits. I think that will be more than adequate for mobile listening and honestly my design skills would be hard pressed to get better than 12.5ENOB at any bitrate. In the future, this thing will be update-able, as all good amps are these days. (even the firmware is OTA update-able).
Updates - Background and Stuffs
All the above is very exciting but let me lay something on here for clarity; Indiegogo.
Indiegogo and Motorola partnered up to do this
https://enterprise.indiegogo.com/motomods/
It is a really great opportunity because it unleashes the power of the Motorola Design peeps onto the world of specificity like headphone amps, glucose meters and other cool things. I won this challenge by submitting my design of the headphone amplifier, they sent me a bunch of cool hardware to get going and here we are. In return, I will use Indiegogo to help start up the project.
I am SUPER excited, and largely terrified because even though I have some (limited) background in EE and CS, it won't prepare me to actually make a product. This will be something that will unfold with time.
There is a common feeling that crowd funding is not a great idea. I have to agree for various reasons.
- I feel that crowd funding puts the word out too soon. This puts pressure on me to get this thing in a box and to your door... pressure is not a good thing.
- I feel that crowd funding creates a false mask of crowd-designing. This is not the case here. While I will be reaching out on forums like this one, the design and all aspects of it are my own and not reallllly open for funders to push me into a box.
There are others but nevertheless I will raise money starting on Indiegogo; it is a great way to spread the word. I would like to sell to forum-ers because I can get some rapid feedback.
I don't intend on making a USB Headphone amp, that space is all jammed up.
I will update this thread when I switch on the Indiegogo campaign (after I get the prototype working). Should be before the end of February!
