Hi Robin
Thanks for your comments. I think I should say that all of my DIY mics (wi=
th the exception of the zoomable parabolic) are really copies/development o=
f ideas gleaned from contributors to this Group. So, many thanks to all wh=
o have stimulated my thoughts and actions via their posts here in the past.=

Thanks for that Mike
I had completely overlooked that the MX391 is, in fact, a Wl183 already mou=
nted on a very small boundary and does therefore might have some boundary e=
ffect benefit as is. I wonder by what amount the effect is increased by in=
creasing the size of the boundary - to 5 1/2 inches square in my case?
This thought raise a second question. Will my EM172 capsules perform in a=
similar way to the MX391s if I reduce the size of their boundary to say, a=
3 inch diameter disc. My limited knowledge suggests they will, but I do n=
ot have the skill or equipment to test this.
I do not have a commercial blimp to follow your ideas with the Rode blimp. =
However, I have been thinking about getting one because I plan to make som=
e cardioid Alice mics (I bought the makings for them some years ago) and ex=
periment with ORTF and NOS techniques. Because the bodies will be DIY they=
can be made quite short and the two mic array should fit nicely in a Rode =
type blimp.
In fact I think I can make a suitable blimp type blimp using some bits I ma=
de some five years ago. Following ideas generated by Rob Danielson, and Al=
lan Haighton IIRC, I made a ORTF arrangement for two Rode NT1As from plasti=
c pipe. This was cumbersome and difficult to support satisfactorily even w=
ith a medium duty tripod - it was therefore put to one side. Looking at it=
once more it should make a very suitable blimp for small size barrier mics=
and the longer term Alice mic based ORTF/NOS experiments.
Five photographs have been placed in a "Two into One Blimp" album. The fir=
st photo shows the components of the original NT1A arrangement. The second=
, one of the arms with support bands at each end. The distance between the=
two sets of rubber bands is 5 1/2 inches. Serendipity? The third photo sh=
ows the fabric mesh end cap. The next photo shows the fine fabric first co=
ver, and the last one shows the dead cats (in fact two of them that meet in=
the middle).
It seems the Alice mic project will have to wait a while. The photos are h=

If any readers think they have stumbled across the Micbuilders Group by mis=
take a nature recording follows.
I went to a nearby wood at about 6pm today. My plan was to catch the eveni=
ng chorus. I got chased home before dusk by heavy rain showers but manged =
to record the barks of a Muntjac deer - at least I think thats what it was.=
Apologies for the traffic and aircraft noise - a fact of life in these pa=
rts I'm afraid. Here is the recording, made with the hand held EM172 bound=
ary rig and the LS-10.
