I emailed the guy running McEar, and he sent me this:   https://drive.google.com/open?id=0B-y9m_RlOls-d254VC1ZeV8zV3lubktwWFVIUjhLV0RfMFpR   Apparently it's fotoplast? I've had trouble curing the resin from McEar too, albeit that may be due to a bad uv light.

Shiloh, I found a viable agar-agar recipe specifically for the negative of CIEMs.     "The usage is very simple, the proportion of agar powder and water, 1: 25-35. The optimum ratio of 1 and 30. The side thrown into cold water while stirring. Until completely dissolved, then heated to boiling...

Shiloh, could you add an independent CI to pretty much any setup, along with a red damper, to add bass? (Without any problems, IE. to a GQ 30783)   ALSO, does anyone want to try a $8 a side triple?   The cross over option on here for $7.50 a...

Does anyone know whether I could substitute a low pass cross over for a CI 30120 with a red damper?   It'd be this set up: (Furco's Opus 3)   GQ-30783  +  no-crossover               +  20x1.93mm tubing  + Orange Damper (3300ohm) CI-30120    + LP@2x(10ohm/33uF)  +  20x0.85mm tubing  + No...

Using the nail base coat leads to a really thin shell, it bends by touching it.   I've tried to increase curing time, from 5 before emptying excess to 15, but it doesn't seem to make a difference.

Thanks!

What does everyone use for prototyping shells?   I've been using medical acrylic until now but it's fairly annoying due to its long shipping time.   I tried using Nail Polish but it wouldn't set, would nail topcoat or base coat set and form a shell?

Thanks! I was just curious because I saw a thread made by a guy who used a similar DIY package.   http://www.head-fi.org/t/817125/my-first-diy-custom-iems   It seems we can significantly reduce start up costs via materials from China.   The armatures I've bought from there are decent, and...

Those armatures are legit - I've bought some CL varients from Taobao before for $1.50 each - the actual cost is mostly the shipping with the forwarding agent.   I've been away for a while , and during that time I compiled a list of materials from Taobao, using these would significantly reduce...

I'm having trouble using agar-agar powder to produce a mold.   I'm using it as a substitute for Knox in a 1:1 ratio.   I've been using about 45g of AgarAgar + 240 ml of water, this yields a mold that falls apart upon the slightest pressure.   Adding too much AgarAgar makes the mold very...

Ah, ****. I saw acrylic and instantly thought UV.

If you want cheap, safe bulk UV resin I found a dental source.   http://dentala2z.co.uk/epages/eshop133027.sf/en_GB/?ObjectPath=/Shops/eshop133027/Products/PRE10054

So I'm getting these cheap armatures (CLs) that I'm testing out shipped out from China today, I've got some photos of them from the warehouse who received the local package. I'll report back with testing against Mouser Armatures in a week or two.   Here are the pictures of the armatures from...

Guys, I've found some really, really cheap drivers on Taobao, like $1.50 for a CL.   I've ordered them and I'll let you know how it turns out when I get them, and compare them to some actual Cl drivers.

Thanks, I'm probably just going to stick with project wire.
