How to build a hi-fi cable for my stereo system without a lot of money?
This question has probably been none, but the answer was probably to quite unexpected. A problem with cables is that high frequencies only transported on the surface of a conductor be, there is too high inside the cable, the self-induction, or eddy currents are too many and the signal is weakened. You can read about this in the Wikipedia under the skin effect . The whole thing was already implemented in real high-end cables and those there to buy: eg click the X Monocle from Kimber Kable ... but consider the price of the like by 1000 is about € ... Who
fun tinkering with the can, but just a Cat5, Cat5e or Cat6 take better cable - because they have a better screening - and to build its cable itself. .... how can all look like this?
Preview .... of cinemafia
material list:
Lan cable, at least 3 times, I recommend 6-7 times longer than the desired length Later,
per channel 2 RCA plugs / terminals, connectors spell or what popular. for stereo consequently 4th ..
tape - much better, however, shrink tubing
tool:
knives, scissors, pliers, soldering equipment, hot air gun for shrink tubing
now the how-to, and ask the first time completely read through before taking action ..:
first Lan cable and attach to the desired length + 10cm least! repeatedly cut off by the patch / LAN cable. recommendation per channel I 3 pieces ... cope cut for stereo consequently 6 small cable.
second a) On one side of the 3 cables, the small inner lines about 5cm, ... depending on the skills ... freileigen and the individual lines Strip - 8 pieces per Lan Cable ... therefore 24 times stripping ...
surprised at the picture, please do not put that on it already covers three of the RCA connector, you should be there now are still not on it, and later one of only!
then solder each half of the 24 cables to the two poles of the RCA connector, this example is available from the Conrad, Pollin, Elektronicteile reichelt or other vendor.
The whole design to be somewhat tricky, because normally only heard a cable plugs into the ... Consequently, the opening of 24 small cable is too small. I have this solved so that I soldered every 8 of the 12 cables per channel per pole to the other 4 of the pole and then almost 2 times (because 2 pole) 4 cable into the connector leads to fit just so and then provided with the solder eyelets - important heat, both cable and eyelet and tin, otherwise you get a bad solder joint - this requires some experience and intuition, and sometimes more than 4 hanging;)
second b) Now you should have the 24 small Kabelchen soldered to the plug, and now you should all with shrink tubing, or alternatively, if not available wrap with insulating tape.
then either make a knot in the cord - I've solved it, or sonstein "stopper" attached so that no force acts on the cable later ... is not absolutely necessary.
3) lichens - now you should have the 3 LAN cable in front of you, on the one side is soldered to a connector. Now places the 3 cables in parallel before you, so they do not cross.
The lichen is now easier than you think. First, it sets the left over the middle in the middle, while the medium moves almost to the left. Now, you put the rights of the in the middle. Now again the left in the middle, then the rights and so on, until you almost reached the other side since. Now you can back your knot
4) Now solder the 2 Connector just like to point 2 at the other end. Re-shrink tubing over it.
done is your Cat5 Audio Cable!
If you well for, what it looks like like this:
Wow ...
If you want it, only without optics and without lichens, like this:
....? ah
by the way, here is another guide ...
I have "something" built differently, because I've built a cable, which distributes the signal from stereo to 6 channels, in which one simply soldered to one end corresponding to 3 male - of course the right cable! .... so that I can provide my 5.1 receiver with stereo, otherwise the rear speakers are too quiet. (Since my Mac OS X only provides stereo ...) to DVD Guggen I'll have my turn on XP ...
I will still try to make a few more pictures and look totally different to even a little bit, but I think it can remain the almost.
Where ... these tutorials will give more often, so I can reach more people with me and to the Web 2.0 to enrich. I
