Several Members have said that when I see the link "click the image to open in full size" that I should use the right click to open in a new tab and then I will be able to see the pic.
But I can't. All I get is an invite to register with some other site.
Why can't we all use the DIYaudio Attach pics procedure?
Sorry if i am off topic.
Can we use solid Copper sheet to make PCB board by the etching process using ferric chloride?

Not like this board exactly because its double sided with plated through holes. But you can try craft a single sided home etched one or hardwired matrix following the schematic in the manual. For personal use only.
Hi!
Can you someone please help me here?
I am trying to make things safety.
I have all settings to connect two R-Ds to a 1702dac board.
I just want to be sure that I am not making mistakes, about the -/+5 volts to the dac board, feeded by two RDs.
You have here a draw with the squematic.
Can you please tell if I am doing it right?
Thank you very much!

Makes sense!
I was not seeing the obvious, a short is always a short...
Thanks Salas, for answering all the time.

I needed to feed a board with 300ma, 3,3v.
If I'm not wrong, for that I need a 1,2ohm resistor in R1.
Well, I don't have it so I installed one with 1ohm.
The heatsink is very hot, it makes me nervous.
Is it the resistor's fault? Is this normal?
I also have a resistor with 1.5ohm, may it's better to install this one,
while waiting for the 1,2MILLS...
By the way, a Mills resistor in R1 makes a big difference....
Thanks.

Of course it works. Making a double polarity supply out of independent and isolated positive polarity supplies is like stacking batteries and wiring a middle tap between them.
Its normal to have hot sinks when using 1 Ohm and running 600mA to cover 300mA which may even be the peak demand with a much lower average. The boards have 5mm pads for accepting Caddock MP925 & MP930 also.

Salas,
between mills and caddock, what are your personal preference?
I mean, on this current draw context.

Haven't directly compared them in that position. Caddock MP 900 series had enough positive subjective recommendations by DCB1 users for setting the main CCS nonetheless. If that info is of any value in a different purpose regulator with different client circuitry to feed of course.
Well, My experience with mills in that position is excellent.
I guess that I will havr to try if I want to havr an objective opinion.
