Hi,

I dont know if it’s the right place to announce that, but i thought it will be a useful information for DIY freaks like me  ;)

Thats why, dear Thorsten: please forgive me that im comin up with another DIy thing in your forum, but i am sure, you will be interrested about this too. You know that i love my midibox NG  :)

I saw today a german magazine (from dezember 2002) called “elektor” (www.elektor.de) with all the shematics, pcb layouts and partlists for an usb audio interface with

1x stereo analog in

1x stereo analog out

1x spdif  in

1x spdif out

1x usb

I personally havent build it yet, but i am planning to. The professional double sided PCBs can also be ordered directly from their web page for about 17 euro. (looks like a profit project, but anyway :stuck_out_tongue: )

This post is not to advertise them of course, but just to announce another DIY baby to our world.

I can’t post any picture of it now, because i haven’t scanned them. Ill try to scan the layouts, pics, shematics and the partslists and send to people via email if they wanna learn more about and can’t find the dezember 2002 release of the magazine. Maybe some of you can host the pics, it would be better instead of sending everyone one by one.

The pcb is as said a doublesided pcb and the size of it is about like a core or MF module.

It uses the IC1: PCM2902 and IC2: OPA2353UA from texas instruments/burr-Brown.

There is a site that i found in the web (www.asio2ks.de)  that gives a free beta release of an universal asio driver for nearly all PCI, USB, Onboard soundcards, if you mail and ask him kindly about. So it could be useful with this diy or even with your onboard soundcard  ;)

Hope this information was usefull.

regards

I think yes. I planned to buy some audio interface for my laptop (it just has some lame mono micro in with a HORRIBLE quality).

Would be very grateful if you can send me some stuff ´bout that!

What about mike? Cant he make these PCBs, too?

Thats the problem, i only have the magazine and they didn’t put any information about it on their website but selling still their pcb for it.  As soon as i finish scanning the pages, i wish that someone could host the pictures for everybody to download. I didn’t give my email to avoid spam, but you can still msg me in this forum.

Wow!

That’s a lot of effort for something so cheap.

http://shop3.outpost.com/product/3113100

It does not have SPDIF I/O, but it’s $29.90 ($9.90 if you believe that rebates actually come).  USB<->audio converters are cheap these days if you look around.  I paid about $59 for mine (not this Telex model) and it compares in quality to a decent outboard D/A converter.

Later!

Smashtv,

On your link is a DAC (digital audio converter) only, but what i am talking about is an USB Audio Interface with ins and outs.  Anyway, i personally would not spend 50-60 dollars to a cheap usb audio int., i would rather solder it by myself and may have fun watching it working.  Like i do with my Midibox NG :wink:
