[sdiy] ASM Capacitors/Bench Power Supplies

> Anybody know a geologist that we can ask?.


finally, something that I actually know something
about...Indian Ruby like Mike said is a great mica for
electrical applications.  But how pure can nature
produce these minerals?  Once you start looking at the
angstrom scale, you start seeing that small
inconsistencies can cause all sorts of
physical/chemical defects.  Inconsistencies including
solid-solutions, varying inter-layer cations, crystal
discontinuity, polymorphs, etc.  

In fact, I battle this every day at work.  We've been
trying to figure out how to automate our "easy"
diffraction analyses but it's almost impossible since
chemistry varies widely in almost all
naturally-occurring mineral species.  That's the
reason why the International Centre for Diffraction
Data has tens of thousands of diffraction patterns on
file to help people identify these minerals by X-ray
Diffraction.  So how many mica caps out there suffer
from all of these things?  Probably many, but I also
know that I like the way they sound in some of my
stompboxes...

p.s. did you know that muscovite de-waters when
heated...
p.p.s. Can I be the resident synth-diy geologist?
