I was the last failure on this cable.
my problems:
1. BNC connectors.
I cant' tell you how many I bought and ruined on this cable. seems there are many different variations of BNC plugs, and they require crimping and not soldering.
I even went out and dumped $60 on a crimper for this (and other) projects. Still can't get the right freakin' connecters. I just dont know what i'm doing w/those.
2. opened up the 3.5mm end only to have a bunch of broken resistors fall out. this was the home-brew attenuator.
my problem here is that i'm not an EE. so I have no clue as to what values these have, how much attenuation they are providing...etc.
This new problem lead me to buy several books on EE basics so that I could learn how to make this.
3. time.
I have too many projects, kids, dogs, wives..., leaving much time only for things that I know I can finish once I start.
good luck.
fwiw, I have rebuilt the original cable, sans -10db pad. PM me your addie and I'll send it back.
Do you have the resistors still? The stripes should tell you what they are... the attenuator should be nothing more than a resistor between hot and ground I believe.
Edit: ok, a little more complicted than that, but still doable
http://www.electronics-tutorials.com/basics/attenuators.htmR1 comes out to ~1156
R2 comes out to ~853
Mouser stocks a metal film 1/4 watt 845ohm and 1.15k ohm resistors, so with $.50 worth of parts you should be all set if my latenight calculations are correct.
P/Ns are 271-845 and 271-1.15k respectively
