@creativeJuice Haven't tested yet.. this is part of a side project, a little breakout box for the bottom USB port in my PC and the headphone jack, probably just some wooden box that I'll put on my desk and put the ports along with some GPIO rails for them in. I currently don't have the female to female part for within the box done yet, but when that's done I'll check and report back :) but I expect the increased ampacity along with the decreased resistance to be able to drive headphones, speakers and stuff like that at a higher volume (because the voltage drop across the wire is lessened).

@Condor nice. But reality can often surprise than theory 😂 But nonetheless keep at it and let me know the outcome 👍

@kenogo the commercial one was about 1.8 times the length of the one I've made.
After further testing I also found out that my measurements were off by quite a bit.. I didn't take into account the resistance of my lab bench power supply's wires (~700mΩ) and just read off my lab bench power supply. After hooking up my scope for a proper 4-wire measurement I was able to determine that the commercial one has a 2.57Ω resistance whereas mine is 420mΩ.
The connectors I've bought from here: http://s.aliexpress.com/uYRZ7ZR3
@shellbug I think it is yes.. but I'm not sure. I just picked it up at a dollar store long ago. The thermal and electrical resistance of the gloves makes them very suitable for high voltage and high temperature applications.. that's all I know. Is there some way to test whether they're leather? -
@Condor I’ve heard you can test for real leather by placing a lighter under it and do a burn test. But I reckon Google also might have the answer to that
-
@ChainsawBaby I've read something about that on Wikihow yes.. due to the price range alone, I suspect that this isn't real leather, after reading about its properties and value. The gloves serve the purpose though, and I'm glad that its production didn't skin some poor animals :)

@Condor I don't know, but if they were cheap it's probably some synthetic leather.
*builds a DIY 3.5mm audio wire out of metal jacks, 28 AWG electrical wire, and Ethernet wire coat as a sleeve*
*measures its resistance by doing 4 wire measurement*
(4 wire measurement explanation => https://youtu.be/L9q5vwCESEQ?t=260)
Turns out to be 800 milliohms for this wire.. well that's crappy. At such a low voltage like what the sound card puts out (30mV peak-to-peak at best) that's gonna heavily attenuate the sound, no?
*measures another audio wire that I bought a while ago with the same method*
3.2 fucking ohms, and my test at 1A significantly heated up the wire too. Turns out that this DIY contraption is 4 times better than the commercial ones out there... Sometimes you really have to dial down to what common standards you're building your own stuff against. And it's relatively easy to build too.. awesome! :)
Well, all I can say is that I'm satisfied ^^
