Hey  @piotrus-g, do you have any examples of bandpass or lowpass filters?

What do you mean by "examples"

Oh,
 
 

1. Trade secrets.

 

1. Proprietary information

 

1. Valuable R&D

 
 
That kind of thing

 
 
LOL   

 

[taiden]

Lol, nope, none of that. I'm trying to write up a quick overview on IEM filters for /r/diems and have very little experience with first order band-pass filters or low pass filters. The common example of a low pass filters makes use of an inductor but I haven't seen any IEMs use one. Any wisdom is much appreciated.

Well, there's probably all you need to know in Sonion's brochure http://www.sonion.com/~/media/Files/Academy/Academy_ProAudio__DocCode_304_V_001_Web.ashx including answer to bold portion above.
1st order LPF can be made by resistor in series and cap parallel to the ground. Just like on scheme I posted few pages back (design no.1, for easier understanding).
 
I'm also quite sure there's some of this knowledge in @Furco's DIY guide.

I wonder what your 3 driver ciem uses? does it use directly 3 driver solutions from Knowles?

Why don´t you open up custom art harmony and post the schematic on youtube

The C3's contents are listed on the site.

Piotr adds a lot to the community, and the Harmony isn't DIY friendly. That's two of many reasons why.

I just found something fantastic for shell-making:
 
CND Color Additives
 

 
 
I think that using these in combination with the existing clear UV acrylic we all use (Dreve Fotoplast, Egger UV, UV nail gel) could yield some really interesting results. Using these additives could result in some... Wizard-ry? 

 
I also found a cheaper source for bulk amounts of UV nail gel topcoat. 
 
What do you guys think?

I started receiving stuff that I ordered, among them some mica powders for nice coloring that I have ordered from aliexpress, pretty cheap 24 color samples of 5 grams each,
awesome stuff. http://www.aliexpress.com/item/24-Colors-Mixed-Healthy-Natural-Mineral-Mica-Powder-DIY-For-Soap-Dye-Soap-Colorant-makeup-and/32373805051.html?spm=2114.031010208.3.10.jq8rs7&ws_ab_test=searchweb201556_2_79_78_77_91_80,searchweb201644_5,searchweb201560_9

Now for using them I think it will be nicer looking painting a coat of uv resin mixed with mica powder inside the shell (which can be transparent or slightly tinted with the matching color) rather than mix it with resin to make the shell. Doing so will yield a nicer result "a la Wizard" if you know what I mean.

like this


I will test different method but I think that doing so I will get a nice shine from the outside as in the picture.

I also been looking into some nail art techniques and they have a lot of tricks that can be applied to make faceplates.One of them is using "nail foil" that can be ordered for cheap which have a ton of designs and can be used to mimic a ton of materials...you can look for instructions and video example all over youtube. I have received some foils and will try to mimic this material called carbon fiber shred used to make knife handles and also used as a prestige material buy Noble for their prestige line.


Now I have a question, what kind of wax do you guys recommend for dipping the ear impressions? Is candle wax good, or do I need something special that melts at very high temperatures?

 

[taiden]

I recommend using paraffin wax!

 

[ForceMajeure]

Isn't paraffin wax the same as candle wax? How do you heat it, and at what temperature does it melt?
Because the agar stuff I bought ("Nicefit" brand hearing aid molding material) have a processing temperature of 47deg celsius.

 

[taiden]

I've seen candles made of bees wax, paraffin wax, and earwax of all things! So I'd say get paraffin wax, so you don't end up with earwax.
 
I heat with a waxing pot with a modified thermostat.

 

[MuZo2]

I tried candle wax and was mess.

 

[tranhieu]

Fiy Noble's predecessor used bee wax.
