Mezmerize DCB1 Building Thread

johnwmclean · 5th November 2010, 11:51 PM

I would like to get underway a build thread particularly devoted for Tea-Bags Mesmerize pcb.

There is already a lot of cross referencing material available, from Tea-Bags blog:

http://www.diyaudio.com/forums/blogs...formation.html

http://www.diyaudio.com/forums/blogs...e-edition.html

A build guide can be found here for the Blue Edition v1.0.4 pcb:

DC-Coupled B1 Buffer Build

I know a few members from the Mesmerize GB are building balanced versions including myself, I’m after as much info regarding this option, in particular wiring schemes for inputs, outputs and switching etc.

Those of you with greater knowledge please chip in when possible

I’m looking forward to receiving my boards and getting started. Many thanks to Salas, Tea-Bag and others.

Let’s discuss.

Thanks for setting this up John.

Is it still possible to get the boards for these?

jimbop, yes it is. PM me for details.

Of course, let it be known I am only distribution talent, no more. This is more significantly Salas great design, and PCBwork by CRT. A global effort if you will.
But this is a builders thread....

So, my advice for today - be careful when selecting LEDs, they want to be 1.8v, 20ma type, and 3mm.

AMB is about to release it’s δ1 relay-based attenuator, it’s prototype faze is nearly complete and production boards will be released soon. It’s designed to work with the LCDuino-1 I/O processor.

The δ1 relay-based R-2R stereo attenuator

This is what I plan to use.

I looked at that attenuator a while back, and it looks interesting. Is AMB planning to release their LCDuino-1 anytime soon?

I have the feeling its very close, from what Ti has posted up recently.

Scouring this forum has yielded very little info for balanced/differential version, but I have found this;

Balanced B1 Buffer

I’m guessing the wiring will be similar for Mesmerize?
