I'm liking the cable and artwork man!

Thanks.
 
In the end, the resin on the faceplates did not cure.... :/
My guess is that I haven't mixed the 2 parts properly....
Going to re-do this test soon.

Aww. Well keep your hopes up borisu

UPDATE 22/08/2012:
 
The resin for test 1 never cured and it turned yellowish.
I repeated the test thinking I may have not mixed the 2 parts properly...
the result? EXACTLY THE SAME.
 
So now I'm suspecting that the hardener part (B) may have reacted with something else causing this to happen.
Because the hardener part is not the most stable substance to begin with. 
White smoke comes out of the container the moment I open it, this is caused by a reaction with water vapor in the air.
(I do all my stuff under a stove hood of course.)
 
So anyway, to test this I placed a drop of the hardener in the plastic transparency film I used to cover the paper with.
and.... as I suspected, it turned a red-ish color meaning some reaction must have occurred.
 
Now I'm back to square 1 with the faceplates.... Damn.
 
After that I went to see if the hardener would react with the surface of a photo-paper 
since it does not absorb liquid and I could print on it.
So far, nothing unusual happened. I went ahead and added some epoxy base (part A) in the mix to see if it'll cure properly on a photo-paper.
Results will be in by tomorrow.
 
That's all for now.

So scientific man!

Hope your new diy works out!

Get a new hardener?

Also, try asking people more experienced with working with these kind of materials for advice.

LOL.

I tried using photo paper instead.

I did, my dad.
He works in the Dept. of Physics and Material Science in a certain Uni in HK

LOL another phase for "I have no idea what you're talking about"
Yeah, sorry about that. It's quite hard to explain what went wrong if you don't know the basic chemistry of resin polymers and hardeners.

Yay I do!

I once asked my dad when I worked with some other kind of resin.
(he went to lab school and did pharmaceutical and organic chemistry)

You probably know more about this than I do, because I haven't gotten to the organic chem topic yet (Still on redox)
And I didn't do any additional research on it.

All I know about Organic chem right now is Meth- Eth- Pro- But- Pent- Hex- etc. and C-C-...-C
LOL

UPDATE 23/08/2012 - Pt.1:
The epoxy on the Glossy Paper cured this morning, It seems to be fine.
Just Laser-printed the Artwork on 240g/m^2 HW Glossy Paper and cut out the faceplates.
Going to do the resin pour when I get home later today...

CONGRATS MAN!

 

[PLUSSOUND]

Very interesting. Curious to see how it turns out.

Me too...  I have been curious as to what it would take to make a set of DIY in-ears.  Keep up the great work!

Just got home with the artwork-printed glossy-papers and poured some epoxy resin on them.
Here's some pics:

It's impossible for me to walk around like that
 
What does IA/01 stand for?
 
What girl is in the pic?
