DIY DC power cables

Just email him. I have made 3 different cables now, not listed yet on his website. 

 

Make sure you bargain. His price quotes tend to be somewhat, um, aspirational.

Guys - help!

 

Did someone here (was it you, @Superdad?) describe a step-by-step here on how to make a serial cable using the Canare 4S6 star-quad cables and the screw terminals?

 

If so, please point me to it, as my searches are coming up empty.

 

I'm doing a bakeoff next week and find myself in need of a way to connect 2 LPS-1s to generate a 12V DC input.

Here you go.  Substitute pairings of star-quad is fine.  Each screw terminal gets only one (pair) of conductors.  The jumper in the middle is from "+" of one plug to "-" of the other.  Imagine the LPS-1s as a pair of batteries you are putting in series.  You take minus from one end of the stack and plus from the other.  Remember, you are not paralleling them!  And oh yeah, set one to 7V and the other to 5V to get your desired 12V.

 

 

Duh, of course. I was overcomplicating things in my head.

 

So the "jumper" in the middle, connecting + to - across plugs: I would just use a section of cable and use just one of the 2 pairs of star-quad, leaving the other pair unattached.

 

Now a follow-up question, for extra credit - or, for some, raving insanity!

 

What if I wanted the aggregate 12V output AND also the 7V output from one of the LPS-1's? What then, sensei?

You guys are making this more complicated than it is!  

 

 

Don't you know us better than that by now? 

 

Wait until you read what we have in mind!

Look ma, I mean @Superdad, my first DIY serial DC cable!

 

Thanks for the pointers!

 

 

Tested it on 2 LPS-1s set at 7V, and was thrilled to read 14V on the ol' multimeter!

I have read similar reports as well as smoke generators from numerous sources.

 

Just need to locate a source.  Maybe George Cardas will sell me a few meters of what he supplies to Pangea?!  ;-)

 

The way the Pangea copy gushes about it, you'd think George personally mines the copper, then lovingly draws them into conductors for our benefit.

I could only find a few sellers here in Asia, they're asking for approximately $145 per meter and no wonder most online stores aren't willing to sell a relatively expensive 16AWG silver wire

Then I read something below and 5N silver should be as good as it gets

Actually Oyaide made their own 5N silver FTVS-910 for AES cables but that looked like a potential candidate for DC cables to me

Diameter of each silver wire is 1.05mm so that's roughly 18AWG

Outer diameter is 8.5mm and this particular DC plug is good for anywhere between 6.3 and 8.3mm

Indeed, the Oyaide FTVS-910 behaves as a very fine DC cable.
