Agree on all points . . .
I fiddled with it a bit and became quickly frustrated with
the latencies associated with remotely accessed applications.
We've go 3meg down/.7meg up connectivity here.

For $13.00 on Ebay, this is a very good basic package, with
a lot of capability to open and edit cad files from Autocad and others.

For very comprehensive information about metal detectors,
take a look at www.geotech1.com. You will find very
extensive pursuit of the subject, and projects that
are examples of good work.

Good question. When the 9004 was conceived, I still had
access to some alternators mounted on drive stands and the
preliminary work suggested the idea was worth developing.
I acquired my own drive stand.
http://aeroelectric.com/Pictures/Alternator_Test_Stand/Alternator_Test_Stand_1.jpg
and started to modify it for development of an aircraft
electrical system and install it in my shop. Even
acquired the single-phase to-three-phase converter
and got a 60A 240 line run out to the garage.
Then I moved to M.L. The fat wire 240 line is 130 feet
away . . . and taxations on my time took a quantum
jump by the unintended acquisition of too much
rental property (houses we intended to sell the
same time the housing market was diving off the cliff).
So now, I have this big machine sitting in my garage
and more man-hours away from a utilitarian state than
before.
Plan C . . . or is it D? I forget. The 9024 is
going to be done first. I'm going to convert the
electrical system in my '87 Jimmy to look like Z-11.
I'll install a suite of 9024's in the truck to make
sure I'm satisfied with the way they work. When
that's done, the truck will become the test bed for
the 9004.
I've got to pick up the drive stand for a third time
and haul it back to the project's benefactor who
requested that I return it when I was finished with it.
In the mean time, the pressure is off on perfecting
the 9004. Many of you will recall my visit to MPA's
overhaul shops and development labs a few years back.
(See chapter 3, in 12th edition 'Connections.)
I witnessed some spectacular demonstrations of five,
max-temperature, max-rating load-dumps in a row on
exemplar alternators.
The engineer in charge asserted that any alternator
builder worthy of the name puts out a product that
is not vulnerable to the occasional b-lead disconnect.
I've concluded that all the floobydust thrown into
the air about AeroElectric crowbar systems being
the kiss of death to otherwise 'perfectly good'
alternators had more to do with throwing sand than
with a sharing of useful information.
