@Eokboy
what wire is the braid? and where did u get those neutriks? id love to get muh hands on them man.

i use a lighter for the heatshrinks

@yeahs4.1
wats that thing u used for the split on ur mini-rca?

Just normal 22 awg tin plated copper wires. And those Neutriks are ~RM5 from RS. Its the gold plated version of the common REAN plugs, which RS also has for ~RM3.

yeahs4.1: Looks like a ferrite bead...

RS??

whats RS? u mean rsmalaysia.com? u actually went to their place n bought ah?

Yea. RS is 5 minutes from my house. How convenient

I just place an order. They don't have all parts in stock, so they put an ETA and if the total order is >RM20 you get free delivery.

yeap, it's a ferrite ring.. for beauty purposes only..
but overall, i'm quite satisfy with this cable although it's my 1st time making a mini to rca..

Just get mini-mini cable tat made by yeah 4.1.
One word to say,great job u done!
good price and good skill u hv

thx, enjoy ur cable~

check it out....

this cable is a 3-wire rounded braid. was initially thinking of making a stereo mini-mini just for fun and to test to see how it sounds...but i couldnt find a plug where the cable would fit the barrel...

the cables are so thick that it cant even fit through the barrel of the Canare F12!!!! all the braiding work wasted



as for what cables they are... theyre spare speaker cables from my car's previous ICE system

cables used in car audio system is damn thick.. and u even took 3 cable to braid them together? lol

yeah....but there are thinner ones out there oso...only thing is these are the only ones i had...and was hoping to be able to use them instaed of just collecting dust

looks like theyll continue to collect dust

just now a bit boring,.
made this cable to play play...







but heatshrink tube is not evently long. hahaha. nvm lah. just for fun..
anyway... i still can't find the shinny heatshrink.. that day walk with lAh0s and akabane in jalan pasar cannot find it... =(

whoa, neat work. especially the braided part.

p/s : i'll try to look out for shinny heat shrink for u next time. will take note of the shop's name

TQ TQ TQ very much..
once i get it. i will replace all my Hong Shan heat shrink.. =P

How much is a 1meter canare cable L-4E6S? i guess can get from pasar road right? didnt DIY cable b4 so i dont raelly noe.

RM7/meter at IC Electronics.

tq very much. appreciate it

finished a new mini-RCA last night. this one with BLING!!!

i also got muhself a new soldering iron...more of an impulse buy

free delivery includes delivery to Penang?

the cable looks evil man...
welcome to GOOT family.
haha i myself love goot more than my hakko.
last time the one i use (roughly RM 150) is not bad.

Me and Eok were talking, sure we lead ears can't hear the difference between cables, but we surely do agree that from an engineering standpoint, superior cabling can be made with enough knowledge. I sure can't hear or can't see the point of building a BMW M6 to drive around the jammed streets of Kuala Lumpur....butbutbut.....it's there and it's a dream.

The price point is high since i've relegated this to be my best work with no real expenses spared. I'll be building building a 3 meter IC, finished depending on my finances to the highest of standards. So here's a list to design goals.

- Minimum Resistance (but enough to kill off reflections)
- Zero Inductive Coupling
- Minimum Impedence mismatch
- Minimum Reflection
- Optimized Conductor use
- Maximum RFI and EMI rejection
- Minimum Inherent body noise
- Minimal handling
- 80dB of 100khz Attenuation
- Intererence free dedicated ground
- Minimized temperature coupling (this part i seriously don't know how to achieve, besides putting heat sinks on the damned thing)

The base core idea is simple, 2 cores of silver wire (best material for low resistance) within clear teflon insulation given the maximum twist ratio without resorting to flat cabling (that becomes a big ass antenna), which then are then twisted with another pair of silver wires in teflon.

If possible here i will pad it with some sort of polyeurathane foam, but so far i have been unable to find a source. It reduces handling noise and increase temp insulation, keeping the wire from heating up due to other sources that can cause thermal agitation and noise. But we'll skip this.

Ok, now for the noise shielding. I seriously have no source on this, but for filtering out high frequency RFI, this is a must due to it's lack of holes like braid (anything with a high enough lamda can slip through a braid shield). So i devised a plan of using either bulk foil with a polymer backing as a shield, or good old cooking aluminium foil cut into strips and then slotted (following the Belden Method) and then wrapped around the two conductors, and then sealed with a proper epoxy.

Secondary noise shielding will be provided by 95 percent coverage copper braid from Alpha wire, this is to absorb EMI and due to it's low resistance it does have very good qualities even when it comes to higher frequencies.

Tertiary noise shielding is provided by a ferrite core, specifically selected to filter out the frequencies that i have calculated to lack in attentuation from the all the above interference rejection methods. The ferrite core has a curved attenuation ratio depending on frequencies, so the ferrite acts as a spot cleaner, patching up attenuation gaps that i might have missed and/or augmenting the other shields.

Finally added on top is plain strong high AWG PVC jacket. The boundaries between the RCA pluges and the stripped shields after the single cable splits into an L and R plug each is to be shielded with 3M copper embossed tape and the material of each plug is to be as closely matched to the wire as possible (WBT silvers )

A point i'd like to make, it's simple why people put connectors with resistance into their ICs, to reduce reflections from the impedence mismatch, depending setup, i don't plan to offer any resistance on the cable itself, although i might add a resistor in series for it. It's trade off between both sides, resistance increases noise, but so does reflections, so i'll let a sampling decide instead. All connections are made with eutectic solder

Lastly the shield ground will be a post meant to be connected to chassis grounded device. This is to make sure no ground contamination occurs. And in theory the noise level should even plunge further.

So i guess that's it. All of the above are generally made with science, matlab (for materials analysis) , mouser, digikey, hakko, qualitek, alpha and 100 percent overkill.

If the first batch goes well, i'll start selling outrageously overpriced ICs to rich goons which keeping them cheap for hobbists! YAY for Capitalism!
