How to make an interconnect Step by Step With Pics - Page 16

post #226 of 1002
i can't answer your question, but was going to pose another to cable gurus.

im guessing that most airlines output their sound in dual mono thru 1/8" jacks. will i have any problems if i just make a 1/4" inline jack to two mono 1/8" plug cable for my summer travelling coming up?

This looks like a balanced cable, but wouldn't this also apply to a stereo cable as well? As for an RCA-RCA cable, one pair should be used for signal and the shield for ground, but the other pair? Signal, ground or nothing?

Finally, would it be better to construct a mini-RCA cable with three pieces of Star Quad so that all sections are shielded?

Thanks,
Brian

So what's the consensus on this?

I'm about to build my first headphone extension with star quad cable and need to figure out whether to connect:

* blues and whites for the signals and shield for ground (as recommended by Canare)

* both whites as ground and blues for the signals (as I've seen several times in this thread)

* some other configuration

dunno if the shiiping and handling cost thing every got resolved, i have not read all 10 pages yet (up to 4) but item cost and shipping was talked about. ill share my recent order totals from them.

this is from markertek

The following item(s) shipped via UPS Ground on 11/29/2004. Tracking # ################

2 [35HDNN] Switchcraft 3.5mm 3 Conductor Plug @ $3.49/ea = $6.98
2 [F-12] Canare Stereo Mini Plug @ $3.30/ea = $6.60

Shipping Charge: $5.66
Sales Tax: $0.00
Handling and/or Misc/Credit: $4.95
TOTAL: $24.19

that was for plugs, this was for cables

The following item(s) shipped via UPS Ground on 11/29/2004. Tracking # #################

1 [L-4E6S WE] Canare Cable Star-Quad White @ $0.36/ea = $0.36
1 [L-4E6S GY] Canare Cable Star-Quad Grey @ $0.36/ea = $0.36
1 [L-4E6S BK] Canare Cable Star-Quad Black @ $0.36/ea = $0.36
1 [L-4E6S OE] Canare Cable Star-Quad Orange @ $0.36/ea = $0.36

Shipping Charge: $5.66
Sales Tax: $0.00
Handling and/or Misc/Credit: $4.95
TOTAL: $12.05

so the lesson learned is to order in bulk. i only bought what i did in the amounts that i did to try my hand before i inveted more that the 36 bucks i did.

update*

So to test my soldering skills and get some practice in before i ruin some of the more expensive cable supplies i bought, i grabbed a super cheap pair from radioshack and tooka crack at it.

so i stripped the **** brand wire i had, now the ground for this wire was bare copper wires wrapped around the 2 inner cables, so i moved it to one side twisted it and used it that way, this wont be an issue on the star quad cable i bought. this is the cable set up not soldered.


a dab of a solder on each wire.


and the completed cable, which measures 6inches perfectly tip to tip.



its decently strong and holds signal just fine and works in stereo*!

* i had an issue with this on a cable i tried to make with out soldering

Thanks for the pics, infiskik. That reminds me that what we're missing from this thread is more pictures of the *soldered* connections. After all, that's the hard part. More detail at this level would be very useful.

that picture isn't good enough??????
post #231 of 1002
i kinda get what he means, like pictures of the actual solder joints.....
post #232 of 1002
np, like i said that was just some **** cable, pics sucked too was soldering on my comp desk and didnt realized my lighting was all weak.

anyway, i followed brschmid guide pictures exactly. so i owe it to him.

i just got my techflex, the cable and plugs should come today. once they do im going to make 3 more cables, il post more pictures using better lighting and the good supplies :P

Did Markertek stop selling the Canare connectors, I can't find the F-12 on their page anywhere.
post #234 of 1002
nope, this link should work for today

http://www.markertek.com/SearchProdu...m=F%2D09&off=2

if not jsut search " F-12 " only and it will bring up 3 results, its the last one that say

Ok, i hate double posting but the 2 are each on their own subject and this one has pictures so i didnt want to combine them.

So as i stated before i got my star quad cable and connectors from markertek

finally had time tonight to bother making some cables.

Im not going to do the walk through like brschmid already did but i will do a pic by pic sequence, with a tiny

description of each.

1. some supplies
A. Star Quad with Techflex on it.
B. 3 extra pieces of quad cable
C. 2 extra pieces of techflex
D. SwitchCraft straight plugs, ones mentioned by brschmid (plugs, barrels, and sleves)
E. Canare plugs, ones mentioned by brschmid.
F. My Kershaw onion knief w/ half serated blade (best wire stripper ever by personal opinion :P )


2. cabl stripped bout 1/2 inch. shows the rubber outside, metal braid, thread, and wires in their natural twist.


3. Cable stripped. see picture for explanation.


4. cable stripped and conductor wires stripped and seperated. barrels and sleves PUT ON.


5. solder points unsnipped. marked 1 2 3, 3 is ground, look at brschmids post for other 2 (its 2am i forget)


6. solder points snipped. still marked 1 2 3.


7. solder points from other end of cable still 1 2 3. (i bent the prongs a tad to make it easier on myself)


8. finished 8 inch cable, with orange star quad and grey techflex, and the switch craft plugs.


Ok, thats the assembly steps, these next pictures go over some tips i figured out to make things a tad easier on

yourself, or atleast they did for me.

1. i think brschmid went over this, but be carefull on how much of the rubber you strip off, and take the time to

compare the depth of the plug and its conenctors. on the first 12 inch cable i made with the grey star quad i

stripped a little too much rubber off and the crappy radioshack plug was not that deep. well as you can see the the

plug isnt deep enough for the amount of rubber i stripped, so i have this horrid gap. i plan to fix it with heat

shrink later.


2. when putting the the techflex on i suggest leaving a tad off since its not expanded you can slip the barrel and

sleve on the cable and flex much easier. youll figure it out pretty quick since the ends of techflex tend to frey

quite bad when trying to slide it on the cable. Also its not the easiest thing to pull on the cable to being with,

but it works like a chinese finger trap, so push it together and then slide it on. And if you look in the assembly

pictures i have the edge of the stripped area taped with blue painters tape (doesnt leave sticky residue) to hold

the techfex tight so it doesnt frey while working on the inner wires.


3. The hardest thing i had to figure out was how to tell which wires were which on the other end. I didnt want to

spend 80 bucks or so on a multimeter, since i didnt have one already. so i did a little improvising. I used a

LED(2)and 4 tiny button cell batteries(1). I stripped all 4 of the inner wires on one side of cable, and only 2 on

the other. i hooked the batteries to the end with the 2 exposed wires(3), then tested each wire on the other side

systematically with the LED. ghetto but it worked.

nice pics, do you want me to add them to the initial post? i can host them from where all my pics are hosted from if you would like.

let me know.
post #237 of 1002
Your more then welcome to host them and/or add them to your orginal guide.

10 pages back some people might not see them :P
post #238 of 1002
ok i got a couple of questions regarding litz braiding cables.

if i want to do a stereo, should i go for: left, right, ground, ground? or: left, right, ground, shield (terminated on one end only)??

then say i want a 1m cable, how much of each would i need to use, say 1.3m? how much wire does the braiding "consume"???

Home Depot sells a multimeter for $8.00 that is accurate enough for probably pretty much everything, especially figuring out which cable is which .
