Perhaps Chinsettawong should consider employing his unique cloning skills to brew some better beer? :-)

A brewer friend of mine once told me that the live yeasts used in some of the worlds best beer can be 'harvested' from a nearly finished bottle and used to produce very high quality home-brew 'copies'.

Best beer brand EVER ( imvho.....)

On topic too! ( diy/cloning, intoxication as a hi-fi tweak! )

At last, they are singing now.  :L3000:

 

 

I use just enough tension to get rid of the wrinkles on the diaphragm this time, and so far I think the phones have been pretty stable.  However, things might change when I put a headband on them.

Aren't you afraid of getting dust between the stator and diaphragm?

You probably can't see from the pictures, but I've put a dust cover on already.

 

By the way, about the noise from dust problem, the easiest way to help solve it is to paint your stators.  I always do that on all my stators.

 

 

I cover the stators with spacers and pray paint them.  I use permanent ink to cover the area where the paint misses out.  Then I chemically etch away the copper on the uncovered area.   If the paint is still in good shape after the etching process, I'll just keep it as is.  Otherwise, I might repaint the stators again.

 

If you do a good job, the copper on your stators is well insulated.  And you'll have less chance of noisy drivers.

The Float number 2 is now singing.  :biggrin:

 

 

The stability is quite a bit better than the previous pair when using 0.5 mm spacers.   But I'm not sure if it's the hole in the middle or the shorter width of the spacer that helps. 

 

Anyway, the phones now have pretty good dynamic and very wide sound stage.  The low bass still rolls off a bit when compares it with my Orpheus clone.  But, it's not bad at all.

Any chance this will turn commercial?

Maybe when I'm old and retired.  :wink_face:

 

However, I highly encourage you to try to make them by yourself.  I'm sure that you'll have a lot of fun.  :bigsmile_face:

The Float v2 looks super awesome. I hope I'll get to listen to it some day. Keep up the good work Wachara

You might be capable of doing something like this, but I know nothing about how to build of stuff like this. I was looking at the directions on how to assemble an Odac and I turned around and ran the other direction. :(

Currently on vacation but will start something when I'm back. Might have to get a few workshops to help with the parts as I have no tools or machinery.

After spending more than 10 hours with the phones, I'm glad to say that the phones are stable with 0.5 mm spacers.  And they certainly sound very good with my KGSSHV.

 

 

Here are the details of my build.

 

1.  The active area is 120 mm x 76 mm. 

2.  The perforated holes are 2 mm with the exception of the large 6 mm holes in the middle

3.  The spacer thickness is 0.5 mm.

4.  The diaphragm is 3 micron.
