A
A
B
Okay,
good
good
yeah,
I
I
don't
know
what
much
to
say
I
mean
I'm
a
ham.
I've
been
doing
some.
I
got
into
some
aerospace
stuff
for
professional
work
and
stumbled
across
ori
kind
of
through
you
know
amsat
and
ori,
and
I
I'm
kind
of
I'm
a
fan
of
open
source
work
and
or
I
seem
to
be
doing
some
good
stuff
in
that
area.
So
I
reached
out
to
michelle
at
some
point
and
yeah
I
mean
I
built
a
as
far
as
rotors
go.
B
I
mean
I've
been
trying
to
figure
out
where
I
can
fit
my
my
skill
set
in
with
ori
income
with
a
busy
schedule
and
when
open
rotor
popped
up
like
oh,
maybe
that's
the
way
to
help
out
I've
built
a
couple
rotors
from
scratch:
rotor
systems
from
scratch.
I've
been
using
the
yazoo
one,
so
I
mean
I've
got
a
little
bit
of
experience
with
them,
but
I'm
no
expert
so
and
I've
done
a
little
bit
of
satellite
stuff,
but
not
a
lot.
A
B
A
All
right:
well,
I'm
steve
conklin,
I'm
on
the
board
for
ori,
and
I
am
a
I'm
a
doubly
by
training.
I've
been
writing
software
for
most
of
my
career
and
I'm
a
generalist
in
a
lot
of
ways,
including
prototyping,
and
things
like
that
and
I've
converted
some
camera
systems
to
as
l
rotator
and
built
the
control
systems.
A
For
for
that
and
there's
obviously
a
need
for
satinax
covers
it
has
a
nice
little
rotor
design
that
covers
very
light
antenna
designs,
but
as
we
as
we
talk
about
geo
and
lunar
and
other
missions
that
might
be
microwave
antennas
and
be
a
little
further
away.
We're
gonna
have
to
point
some
larger
dishes
and
so
we're
looking
for
something
that'll
point
1.2
or
even
a
2.1
meter
dish,
and-
and
so
we
can
talk
about
that
later
after
we
finish
the
introductions
I'll
kick
it
over
to
michelle
next.
C
Oh
sure
hi,
no,
I'm
the
co-founder
and
current
ceo
of
open
research
institute.
My
background
is
information,
theory,
icky,
math
and
forward
air
correction,
and
things
like
that.
So
most
of
my
background
is
going
to
be
at
baseband
background
in
asic
design
and
fpga
design
systems,
design.
Things
like
that
and
there's
a
need
for
open
source,
rotor
and
rotator
designs
for
all
sorts
of
work,
but
of
a
primary
interest
to
us
is
all
of
the
amazing
amateur
missions
with
a
move
to
a
microwave
banned
and
higher
orbits.
C
Your
other
options
are
military,
industrial
or
high-end
commercial
and
those
are
really
out
of
reach.
For
for
everybody
that
wants
to
get
involved
in
amateur
work
on
the
low
end,
we
had
things
like
portable
rotation.
Sat
nags
is
a
really
good
entry
here,
but
but,
as
steve
says,
it's
for
lightweight
devices.
C
C
So
my
my
mechanical
background
is
in
automotive,
mainly
so
I
know
how
to
grind
valves
and
magnaflux
heads
and
things
like
that
as
and
I
need
to
do
basic
machining.
So
so
I
can
help
a
little
bit
there,
but
I'm
not
a
mechanical
engineer,
and
I
know
that
we
have
some
challenges
here-
that
somebody
with
a
lot
more
skill
and
mechanical
design
is,
is
going
to
have
to
fill.
C
C
There's
been
a
number
of
open
source
efforts
in
this
area
and-
and
it
serves
us
very
well
to
keep
regular
patrol
and
to
to
go
out
on
github
and
get
lab
and
in
the
community
to
see
what
people
are
doing,
because
there's
lots
and
lots
of
starts
and
runs
at
this
problem,
because
it's
it's
acknowledged
and
and
widely
perceived
as
a
problem
in
the
community.
You
know
we
don't
have
a
good
solution,
that's
accessible,
affordable
and
covers
leo
to
to
geo.
C
C
D
I'm
here
because
I
I'm
scheduled
challenged,
you
can't
read
any
schedules
to
figure
out,
because
this
is
an
interesting
place
to
hang
out
and
my
background
is
in
hardware
and
fpga
design,
embedded
systems
and
I'm
currently
vp
of
tapper
and
working
on
the
tangerine
sdr.
That's
not
no
mechanical
background.
I've
used
as
l
rotors
to
set
up
satellite
systems,
but
they're
really
expensive
these
days,
and
this
is
a
good,
be
a
good
thing.
C
D
That's
a
good
question
because
there's
been
a
lot
of
discussion
about
what
kind
of
antennas
that
we
use,
because
one
of
the
things
that
we're
trying
to
achieve
is
some
kind
of
consistency
across
the
stations,
because
we're
going
to
have
a
lot
of
different
stations
connected
to
the
internet
and
everybody's
going
to
have,
I
mean.
Hopefully
everybody
has
the
same
radio
now
that
we're
building
the
sdr.
But
the
antennas
are
problematic
because
they're
going
to
be
different,
everybody's
going
to
have
a
different
one,
their
feed
line
length
is
going
to
be
different.
D
Your
type
of
feed
line
is
going
to
be
different,
is
it
directional
or
not?
Does
it
even
need
a
rotator
or
not?
I
mean
these
are
the
questions
that
nobody's
really
answered
yet
because
we
haven't
come
up
with
a
standard
antenna,
but
if
we
could
come
up
with
some
open
source
type
of
inexpensive
rotor,
we
I
doubt
that
we're
going
to
need
anything
as
big
as
two
meters
in
it
like
in
a
dish
but
and
I'm
not
even
convinced
that
we
need
directional
antennas.
D
Yet
that's
kind
of
an
open
question
that
we
haven't
answered
and
once
we
get
hardware
it's
going
to
have
to
be
answered,
because,
ideally,
what
we
would
do
is,
we
would
say,
go
to
dx
engineering
and
buy
a
model
abc.
You
know,
put
it
on
your
hook
and
set
it
up.
But
if
it's
directional,
the
cost
of
a
rotator
is
going
to
pretty
much
be
bad
news.
It's
going
to
cost
as
much
as
the
rest
of
the
system.
A
Yeah,
that's
another.
That
brings
up
another
point,
which
is
that
we
haven't
ruled
out
here
that
we're
looking
at
a
family
of
rotators
assemblies
that
we
can
put
together
and
I
think
the
main
driver
for
doing
something
at
that
more
complex
like
that,
would
be
to
try
to
break
it
up
into
cost
cost
tiers
right.
You
you,
it's
obvious,
just
the
mechanical
parts
to
build
a
rotator
that
can
swing
a
two
meter
dish
are
going
to
cost
more
than
something
that
can
swing
a
a
one
meter
yagi.
D
A
A
The
design
goal
here
is
to
make
this
not
just
an
open
design,
but
one
that's
buildable
by
people
all
over
the
world
with
a
minimum
of
experience
with
with
hand
tools
if
possible,
which
rules
out.
You
know,
fancy
tig,
welding
or
fancy
machining,
where
you
have
to
line
a
bunch
of
things
up,
and
so
the
the
options
we
have
here
include
specifying
parts
like,
for
example,
there
are
a
lot
of
really
inexpensive
front
wheel,
bearing
sets
for
cars.
A
You
pick
a
popular
model
like
an
early
toyota
or
something
that
is
available
around
the
world
and
you
can
find
a
wheel
bearing
assembly,
for
you
know,
20
under
20
bucks.
Two
of
those
they'll
support
thousands
of
pounds.
If
needed,
they
have
ball
bearings
built
into
them
or
or
you
know,
conical
bearings.
A
D
How
how
about
you
buy
the
spindle
from
a
ford
pinto
and
a
brake
drum
from
a
ford
pinto
and
the
bearing
set?
And
you
got
something
I
mean
that's
a
bad
bottle
to
pick
but
pick
some
common
vehicle
and
you've
got
a
big
hunk
of
metal
that
costs
25
bucks
for
a
new
brake,
drum
or
50
bucks,
and
it's
got
holes
drilled
in
it
and
you
could
just
make
the
the
attachment
to
it
for
the
antenna
that.
C
A
D
A
D
What
the
thing
that
would
be
cool
is
especially
you're
talking
about.
I
mean
I'm,
this
big
modular
fan
right.
You
want
to
run
a
little
antenna.
You
want
to
run
a
big
antenna.
Well,
maybe
you
say
we
don't
care
what
model
car
you
use.
I
mean
you
have
to
get
the
bearing
and
the
spindle
and
the
drum
to
match.
C
D
C
C
You
know
the
kind
of
like
the
first
stake
in
the
ground
was
okay.
Well,
instead
of
making
people
make
it
themselves
or
using
something
commercially
you
know
available,
for
that
was
specific
as
a
rotator
which
narrows
your
field
by
quite
a
bit.
Why
don't
we
take
advantage
of
something
that's
available
globally,
so
that
anybody
anywhere
through
the
most
widespread
automotive
parts
that
you
buy
this
that
and
this
and
then
you
may
only
need
to
build
that.
You
know
and
and
if
you.
C
D
A
Makers
will
be
able
to
use
this
as
a
basis
for
many
different
variants
and
then
the
another
part
of
this
is
that
there
will.
I
anticipate
there
will
be
pieces
that
you
can't
just
buy
off
the
shelf
that
are
specific
to
this
design
and
for
those
will
try
to
manufacture
those
in
a
way
that
or
or
make
them
manufacturable
by
people
in
the
community.
A
C
C
Yeah
so
the
first
I
mean
the
first
round
of
reviews
from
the
local
mechanical
engineers
that
that
looked
at
it.
You
know,
after
the
first
kind
of
after
they
first
stepped
back
and
went
oh
well.
Well,
that's
an
interesting
way
to
do
mechanical
design.
You
know
that
it's
not
a
blank
paper
that
they
don't
get
to
design
something
from
scratch
and
then
and
then
machine
or
or
you
know,.
C
C
B
D
A
C
A
We
need
to
repeat
that
medical
engineer
right,
I'm
a
I'm
a
basher
right
now.
This
is
covered,
the
the
repo
which
the
link
was
posted
in
chat.
The
repo
contains
sort
of
seed
documents
for
the
overview
of
the
mechanical
designer
to
try
to
lay
out
these
principles
and
we
take
pull
requests
yeah,
it's
the
strongest
way.
I
can
put
it
if
you
have
opinions
that
are
backed
by
engineering
knowledge,
then
we're
happy
to
do
that.
D
A
B
D
C
Was
I'm
not
saying
that
that
was
bad?
That
was
like
wow,
that
was
and
by
the
way
it's
cheap,
like
they're
like
you've,
you've
quota
busted
here,
you've
you've
gone
way
past
what's
commercially
available,
and
but
you
know,
but
having
said
that
that
that
one
engineer
was
like
wow.
This
is
great
and
the
other
one
was
like
nah.
This
will
never
work.
So
that's
that's!
That's
where
we're
at
with.
C
C
Seeing
if
it
lasts,
and
and
and
all
of
that
that
to
me
that's
the
next
step,
I'm
I'm
firmly
biased
in
the
get
it
working
over
the
air
as
quickly
as
possible.
You
know
making
a
prototype
or
clapping
this
stuff
together.
So
so
that's
that's
kind
of
my
point
of
view
and
I'm
I'm
ready
ready
to
write
checks
or
with
a
credit
card
to
what
I
don't
know
what
we
need
to
get
next.
I
don't
know.
A
C
I
oh
they're,
pretty
standard,
I
mean
we
have
the
data
sheet
for
the
dishes.
They
were
a
very
nice
donation,
so
we
have
upwards
of
30
of
these
ready
to
go
to
to
put
together
on
stations
and
and
send
out
you
know.
So
that's
a
a
nice
asset
to
have
but
they're
pretty
standard,
they're,
they're,
nice
sheets.
C
Oh
yeah,
I
think
we
were
still
looking
for
the
mass,
though,
because
jay
pointed
out
that,
like
they
didn't
have
the
mass,
you
know
the
the
weight
of
the
dish
and
I
actually
wrote
back
and
forth
with
the
the
tech
support
from
the
company.
Who
was
who
insisted
that
the
information
was
in
on
their
website.
I
don't
think
I
ever
actually
got
an
answer,
so
I
think
what
we're
gonna
have
to
do
is
ask
our
volunteer,
who
has
them
in
storage
to
go
away
them.
A
C
Of
chicago
and
then
we're
going
to
move
them
to
the
remote
lab,
that's
being
set
up
in
arkansas,
so
remote
lab
south
is
where
they'll
eventually
be.
You
know,
because
the
volunteer
has
been
very
generous
in
storing
30
1.2
meter
dishes
for
us,
and
in
addition
to
that,
we
have
three
six
foot
dishes,
you
know
are
essentially
two
major
dishes
that
will
also
get
set
up
as
an
antenna
farm
for
all
sorts
of
citizen
science,
open
access
dishes.
A
You
said
all
of
the
dishes
will
fit
in
at
like
an
18-foot
flat,
trailer
yeah.
The
other
thing
is
that
those
dishes
have
one
one:
one
there's
only
one
arm
for
them
to
support
the
lna
or
antenna
at
the
focal
point,
but
we
can
use
that
as
a
model
to
manufacture
all
the
rest
that
we
need,
and
I've
already
committed,
along
with
the
the
person
at
the
southern
lab
headquarters,
to
to
go
ahead
and
figure
out
that
out
and
get
those
cranked
out.
C
B
B
B
B
B
B
It
was,
I
think
it
was
probably
12
pounds
or
something,
and
so
then
I
said
well,
if
we're
doing
the
two
meter,
then
I'll
just
make
it
50
kilograms
as
a
target,
but
I
think
vertical
load
from
some
of
the
other
specs
I've
seen
on
rotors
vertical
load
is
not
usually
the
limiting
problem
because
you're
just
on
bearings
and
it
I've
seen
specs
for,
like
even
the
yeezy,
I
think,
can
take
hundreds
of
pounds.
No
problem.
D
You're
using
automotive
grade
parts
they're
rated
for
you,
know
tons
of
force
some,
even
even
if
you
use
a
pipe
with
two
conical
bearings
and
mount
the
dish
on
top,
then
you
get
the
sideways
the
torque
wind
load.
It's
still
not
very
much
compared
to
like
the
cornering
that
the
wheel
gets
on
a
car.
Well,.
C
C
Yeah,
that's
a
good
that
was
kind
of
our
hope
is
by
you
know,
saying:
okay,
what's
commonly
available,
that
we
have
a
background
in
I'm
like
well,
why
not?
You
know
they're
talking
about
bearings
and
and
the
failure
of
rotors
and
the
stories
of
all
my
friends
who
have
like
I'm
on
my
third
yeah
rotor.
You
know
in
a
couple
of
years
and
oh,
why
is
this
the
weak
link?
You
know
what.
C
Didn't
make
sense
to
me
with
an
automotive
background,
but
it's
like
okay,
it
may
not
be,
and
we
need
to
have
this
reviewed
like
by
when
we
need
more
eyeballs
and
and
do
the
full
open
source
treatment
on
it.
But
you
know
that's
that's
one
of
the
the
things
that
we're
saying
is
like.
Okay,
we
can
address
this
part,
that's
been
a
a
weak
link
in
the
chain
in
the
past
and
then
okay.
What's
the
next
thing
that
breaks
yeah.
D
C
Thing
that,
like
steve
conklin,
found
some
really
amazing,
portable
or
mobile
deployable
dishes,
where
it's
not
up
on
us
on
a
on
a
mast,
and
you
know
turning
and
as
al
the
traditional
azel
rotor
it's
down
on
the
ground
and
it's
a
sort
of
a.
I
don't
know
a
stator,
almost
like
a
push-pull
doodad
and
the
whole
thing
is
in
a
frame-
and
I
know
I'm
not
being
very
super
clear.
C
It's
like
a
linear
actuator,
that
is,
that
is
making
an
entire
frame
lift
up,
and
it's
it's
sitting
on
the
ground.
So
this
is
one
of
those
things
that
you
buy.
If
I
guess
you're,
you
know
a
spy,
I
don't
know
you
know
so
you're
going
out
and
you
have
your
briefcase
and
you
you
fold
it
out
on
the
ground
and
and
it
there
is
still
some
moving
parts
and
then
going
beyond
that
to
to
some
of
the
other
products
that
that
have
been
available
or
or
been
floated.
C
Before
is
a
phased
array
that
you
literally
just
throw
on
the
ground,
and
you
you,
you
open
your
briefcase
and
you
you
fling
out
your
phased
array
antenna
and
that's
it.
It's
just
a
phased
array
that
lays
on
the
ground
and
all
of
the
smarts
and
all
the
expense
is
then
in
this
electrically
steerable
doodad.
D
C
You
can
see
it
scattered
around
in
some
ieee
journals
and
papers.
So
so,
yes,
I
don't
know
of
any
affordable
prototypes
or
affordable
products
in
that
category.
It's
all
stuff,
that's
it's
very
expensive,
but
you
know
the
basic
math
is
accessible
to
us
and
you
know
if
we
back
up
and
approach
it
in
an
open
source
sort
of
pragmatic
maker
fashion.
D
C
D
So
if
you
make
the
mechanically
steerable,
then
you
could
bolt
any
old
antenna.
You
want
on
there
and
you
can
use
it
to
make
it
electrically
steerable.
Now
you
got
to
design
it
into
the
antenna
like,
I
think,
that's
what
you're
saying
steve
now.
It
becomes
part
of
the
kind
of
design
and
that's
not
what
you
want.
B
C
C
A
C
C
C
C
So
when
we
get
out
to
this
area,
there's
not
a
strong
tradition
of
open
source
involvement
or
or
open
source
work.
So
I
mean
are
we
are
we
looking
at
like?
Should
we
should
we
step
back
from
ambition
and
like
scale
things
back
or
or
should
we
just
accept
the
fact
that
we
might
need
to
contract
out
and
pay
people
to
do
the
evaluation
that
we're
talking
about
doing
like
in
software
design?
C
We
could
pull
off
and
have
and
frequently
do
pull
off
design
reviews
for
software
and
open
source
community
and,
like
you,
mentioned,
pull
requests
but
like
to
to
the
mechanical
engineers
that
I've
talked
to.
They
have
no
idea
what
a
pull
request
means.
They
have
no
idea
what
what
you
do
for
open
source
involvement.
A
One
well
within
the
realm
of
mechanical
engineers
that
don't
understand
open
source.
They
certainly
understand.
If
we're
going
to
pay
somebody
or
whether
they're
volunteer,
go
and
do
this
thing
and
provide
a
set
of
prints.
It
can
be
used
to
build
it,
and
then
it
would
be
up
to
us
if
we
hired
them
to
decide
whether
to
open
that
design
or
not.
And
of
course
we
would
so
hiring.
B
D
D
So
if
we
say
we've
got
a
1.2
meter
dish,
it's
this
high,
it's
this
big.
It
weighs
50
pounds
or
50
100
pounds.
How
much
torque
do
we
need
to
get
our
azimuth
to?
Because
what's
going
to
happen,
is
I
see
it
says
six
degrees
per
second,
but
that
includes
startup
time
and
breaking
time.
So
that's
going
to
depend
on
the
mass
of
the
thing
that
you're
trying
to
turn
and
the
size
of
your
motor
and
the
size
of
your
gears
right
and
then.
A
D
Well
suppose
the
mechanical
guy
says
well,
you
need
a
25
horsepower
motor
to
do
that,
but
you
could
get
three
degrees
per
second
with
a
three
horsepower
motor,
or
I
mean
it's
something
along
those
lines
you
could
say:
well,
okay,
maybe
six
isn't
really
that
important
if
it's
going
to
cost
us
a
fortune,
so
let's
get
and
so
what
we
did
on
the
weather
station.
We
said:
okay
for
the
dollar
figure
that
you
have
as
a
target.
This
is
what
you
can
get.
Is
that
worth
it
or
not?
Okay,
is
it?
D
A
Right
or
maybe
that's
the
cost,
that's
the
upgrade
option.
That's
the
cost!
Difference
right
that
you,
you
need
mechanically
if
it's
all
the
same
and
you
can
buy
speed
by
buying
a
bigger
motor
and
tuning
the
control
system
differently.
Then
that's!
Okay,
if
you,
if
you
need
that
ability
you
pay
for
that
ability
right.
D
Especially
if
you
over
design
the
mechanical
support,
because
it's
cheap,
because
you
could
buy
five
dollar
bearings
and
then
that'll
support
a
one
horsepower
or
a
five
horsepower
or
ten
horsepower
motor
you
pay
for
the.
How
much
horsepower
you
want
all
the
other
stuff
remains
the
same,
because
it
handles
any
of
them.
C
C
D
A
You
know
one
of
the
things
we
could
do,
which
we've
done
before
we
did
it
for
some
orbital
calculations
that
we
need
is
we
we
we
hit.
I
have
a
pretty
good
network
of
nasa
and
nasa
contractor
people,
and
I
could
just
put
out
a
call
for
volunteers
and
some
of
those
guys
are
mechanical
guys
and
I'll
bet.
They're.
C
A
A
Let
me
start
shaking
the
tree
and,
and
you
can
too,
I
know
you
have
contacts
and
generally
as
long
as
the
rules
kind
of
are
as
long
as
this
doesn't
conflict
with
anything
that
nasa
is
doing
and
as
long
as
we
don't
claim
that
these
people
are
like
and
nasa
is
endorsing
our
project
or
whatever,
and
we
just
name
them
as
as
individuals.
Then
there's
not
a
conflict
right.
C
A
C
B
D
D
C
D
D
B
Similar
note
there
I
have
a
question
I
think
michelle.
Maybe
you
can
help
out
with
this
one
if
we
want
to
hunt
down
parts
like
that
are
common
for,
say
the
toyota
corolla,
what's
a
what's
a
good
resource
to
do
that
with?
Is
there
like
a
toyola
corolla
parts
book
with
the
part
numbers
in
it
somewhere
that
I
don't
know
what
it
would
be
called.
C
Yes,
there
are
there's
a
cross
reference
for
for
auto
parts.
So
what-
and
so
the
answer
is
yes,
the
information
is
there
and
we
have
people
that
can
can
help
with
that.
It's
a
little
tricky.
Sometimes
you
can
find
this
this
stuff
on
the
on
the
internet.
You
know,
but
the
cross
reference
books,
you
you
wander
into
a
friendly
shop
or
or
or
what
have
you
and-
and
you
can
get
the
information
and
toyota
themselves
actually
might
be
very
interested
in
helping
support
this
direct
from
the
essentially
direct
from
the
manufacturer.
C
I've
done
similar
things
for
this
in
in
amateur
auto
racing.
So
I
I
was
just
like.
Well,
I
mean
we
just
use
the
same
sort
of
sort
of.
You
know
part
service
that
you
get
when
when
you're,
putting
together
projects
for
for
racing
and
then
in
terms
of
like
actually
getting
the
parts.
What
what
we've
done
here
for
for
maker
and
burner
projects
is
just
go
to
the
u-pull
at
auto,
auto
yards.
You
know
it
one's
named
econo
out
here
and
it's
this
gigantic
field.
C
D
So
how
much
are
you
willing
to
leave
up
to
the
builder
to
customize
himself
rather
than
say,
here's
the
plans
go,
buy
part
number
one,
two,
three,
four
five!
The
problem
is
the
part
number
one,
two,
three
four
five
might
cost
you
50
bucks
and
it
might
cost
me
200
because,
but
if
I
change
the
part
number
to
two
three
four
five
six,
it
might
work
just
as
well,
but
be
a
little
different
configuration
right.
A
I
think
we
produce
a
reference
design.
That's
that's
guaranteed
to
work
as
built
with
a
set
of
reference
parts.
Just
like
you,
you
get
a
a
development
board
from
intel.
It
has
fixed
parts
on
it.
You
build
it.
You
know,
you
know
that
that
works.
If
you
build
it
exactly
that
way,
you
know
it
works.
If
you
want
to
go
off
on
your
own
and
do
part
substitutions
and
then
that's
fine
and
that's
encouraged,
but
that's
on
you.
D
A
D
A
A
four
with
like
four
m
10
volts
or
whatever
they
are
right
so
such
right
right
because
they
put
studs
on
there,
yeah
so
and
and
the
whole
reason
we
keep
coming
back
to
automotive
parts
is
because
they're
plentiful,
they're,
relatively
cheap
and
they're.
There
are
millions
and
millions
and
millions
of
cars.
C
D
C
C
D
D
C
D
C
No
ice
so
yeah,
you
know
so
there's
been
satnag
stations
that
have
survived
some
bad
storms.
High
winds,
brutal
conditions,
you
know
I
mean,
and
it's
like
well
you,
but
you
just
make
another
one.
You
know
so
you
just
keep
printing,
you
know
and
you
have
it
in
stock
and
you
just
keep
going
and
it's
you
know
the
design
is
yeah.
Last
time
I
the
last
time
I
did
any
printing
for
satnags
was
version
three
and
it's
it's
progressed
beyond
that.
You
know.
So.
C
This
is
one
of
those
things
that
attracts
this
entire,
huge
swath
of
makers
with
3d
printers.
You
know
that
are
that
have
the
and
and
also
lightweight
antennas.
It
is
it's
lighter
weight
than
what
we're
talking
about,
but
they
really
want
to
move
up
in
frequency,
and
then
you
move
up
in
frequency.
You
start
talking
about
dishes.
B
A
And
the
commercial
options
are:
are
they
they
run
a
spectrum
from
cheap
and
terrible
to
outrageously
expensive
for
what
they
are
and
that's
because
I
don't
think
they're
selling
too
many
of
them.
It's
a
there's,
a
name
for
that
problem,
they're
priced
so
high
that
they're
not
selling
too
many
of
them.
So
there's
no
mass
production
right.
A
A
C
B
C
And-
and
you
know
so-
six
foot
dishes
that
are
publicly
accessible
over
the
internet.
You
know
that
here
you
go
here's
additional
capacity
for
a
larger,
getting
into
larger
discharge.
I
know
six
foot
doesn't
sound
like
a
lot,
but
it's
it's
something
that
is
hard
for
an
individual
to
field
and
it
adds
to
the
the
capacity
that
we
have
in
the
the
amateur
core.
You
know
technical
core
and
that's
the
spit
is
the
rotor
to
get
that's
just
the
the
one
choice.
Yeah!
That's
the
thing
that
you
get
like.
C
D
C
D
D
A
Now
now
for
control
speaker
since
we're
talking
about
network
stations
and-
and
you
know,
satnags
is
built
on
that
principle,
and
we
want
to
extend
that
there
is
a
it's
it's
a
simple
matter
of
software.
Once
we
get
the
control
system
going
to
convert
one
frame-
and
I've
done
this
before
I've
written
these
translators
and
ham,
in
fact,
hamlib
or
hemlob,
depending
on
how
you
pronounce
it
has
a
bunch
of
different
rotor
interfaces
and
a
common
language
that
you
can
use
to
drive
them.
So
I'm
not
I'm
not
too
worried
about.
A
A
B
What's
the
what
are
the
expectations,
because
you
know
like
yay
zoo,
you
can
spend
700
750
and
get
something
that
you
might
maybe
it'll
move
a
half
meter
dish.
Maybe
it'll
move
a
meter
dish,
I'm
not
sure
so,
like
you
know,
if
you're
in
the
thousand
dollar
range
that
you
we
may
end
up,
that
a
thousand
dollars
is
not
an
unreasonable
price
for
the
parts
once
you
start
adding
motors
and
other
stuff
in
so
so.
What's
what
is
the
feel
of
the
expectation
of
where
we're
shooting
for.
B
C
B
C
Oh,
that's
a
big
problem
right
now.
No,
so
I
know
that
that's
I'm
being
partially
facetious,
but
like
I'm
starting
like
okay,
what
is
because
750
you
know
for
for
some
of
these
rotors
a
thousand
up
to
3
000
for
and
I'm
like.
I
think
we
can
do
a
whole
lot
better,
but
the
the
unknown
is
what
kind
of
motor
do
we
need
and,
as
steve
said
early
on
like
well
leverage
you
know,
gearing
up.
Is
your
friend
you
know
look
you
can
you
know
so.
A
A
A
Right
but
a
dish,
one
method
of
of
doing
a
dish
is
to
do
a
flat
mount
in
the
center
of
the
dish
right
and
count,
and
you
still
counter
weight.
But
it's
a
it's
a
different
mechanical
structure.
If
you
look
at
the
the
way,
a
lot
of
camera
mounts
look
are
used,
that's
typically
what
they
do.
So
the
end
of
the
the
back
side
of
the
dish
ends
up
being
offset
from
the
the
elevation
rotational
axis
by
you
know.
A
I
don't
know
eight
inches
if
you,
if
you
get
that
all
or
six,
if
you
can
get
it
all,
really
tight
yeah,
and
that
is
essential
to
whoever
is
going
to
do
the
mechanical
evaluation
of
this.
Knowing
sure,
if
you
take
a
200
pound
dish-
and
you
say,
that's
the
dead
weight
where's
the
center
of
gravity
of
that.
Well,
if
that's,
if
that's
a
foot
off
of
the
rotation
and
then
you've
got
counter
balances,
that
means
you're
hanging,
probably
I'm
just
going
to
roughly
say
400
pounds
off
of
the
thing.
C
C
Yeah,
this
is
why
we've
punted
on
some
of
this
stuff
over
the
past
year.
This
is
exactly
why,
because
it's
like
it's
wandering
outside
of
what
we
know
and
and
because
we
we
did
figure
out
that
okay
say
it's
a
three-inch
mast,
just
say
it
that's
what
it
is
and
that's
that
and
that
covers
an
enormous
quantity
of
commercial
dishes
that
somebody
might
have.
So
the
other
alternative
is
that
we
specify
exactly
which
dish
we
want.
We
just
say
that
this
is
what
you
get.
A
Well,
we
can
also
specify
it's
a
three
inch
mast,
but
we
want
the
swing
we
want.
We
want
to
be
able
to
swing
something
at
180
degrees
within
x,
x,
number
of
centimeters
of
that
or
x
number
of
inches
of
that
mass,
and
then
it's
up
to
you
to
attach
to
that.
If
you,
what
I'm
getting
at,
is
you
if
you
have
a?
C
So
maybe
the
next
step
is
to
start
talking
to
the
people
that
you
have
in
your
network
and
and
I'll
do
whatever
I
can
to
make
a
meeting
happen
as
soon
as
it's
safe
as
soon
as
we
can
meet
in
person.
That
sounds
like
an
in-person
like
a
symposium
or
something
like
that
might
be
the
right
thing
and
that
we
take
this
particular
recording
and
we
we
put
it
out
there
and
say,
show
us
where
we're
wrong
come
tell
us
where
we're
wrong.
C
Please
please
do
and
listen
carefully,
and
then
you
know,
based
on
those
two
things.
You
know
the
feedback
from
essentially
the
open
source
community
and
from
the
rest
of
our
eye
and
then
working
through
our
network
to
try
to
put
together
an
intentional
meeting
at
that
point
once
we
are
educated
enough
from
these
efforts
that
we
should
hire
somebody
and
that
you
know
we
say
okay
now
we
need
to
need
a
design
review
it
and
then
move
forward.
That
might
be
a
good
plan.
D
See,
I
think
the
thing
that
the
more
you
know
about
what
you
want
is
the
end
product,
the
less
it's
going
to
cost
you
yeah
and
the
more
likely
you
are
to
get
somebody
who
will
actually
be
able
to
do
it.
If
you
just
say
well,
I
need
a
nozzle
rotor
and
it's
got
to
use
a
brake
drum
and
a
spindle
you're
not
going
to.
I
agree
if
you
say:
okay
now
take
this
toyota
brake
drum
and
you
take
this
toilet
spindle
and
these
bearings
and
then
you
gotta,
have
the
dish.
Mount
is
like
this.
A
D
Been
the
bane
of
the
existence
at
the
company
in
our
company
is
that
the
guy
comes
in
the
door
and
he
says.
Oh,
I
got
this
great
idea
and
of
course
he
thinks
that
his
idea
first
is
worth
millions,
because
it's
the
idea,
I
mean
that's
what
really
counts.
You
know
you,
you,
people
that
implement
it.
You
just
the
workers
right.
D
D
So
that's
his
million-dollar
idea:
now
you
peons
go
off
and
figure
out
how
to
do
it.
Well,
I
go
the
decisions
we
make
here
and
the
designs
that
we
put
forth.
This
is
going
to
determine
really
whether
you're
going
to
be
a
success
or
a
failure
with
this
product.
If
we
pick
some
screw
ball
solution
and
go
off
down
that
road,
you're
going
to
spend
a
whole
bunch
of
money,
it's
not
going
to
work
and
then
it's
going
to
fail
and
you'll
that'll
be
the
end
of
it.
D
But
if
we're
really
smart
and
we
happen
to
figure
out
something
that
will
work,
then
it's
going
to
be
a
success.
It's
going
to
cost
you
less
money,
but,
and
so
so
that
piece
right
there
picking
the
the
architecture.
If
you
will
that's
the
valuable
part
we
could
never
get
paid
for
that
we
get
paid
for
building
circuits
yeah,
but
what
the
circuit
is
that
you're
going
to
build
that
nobody
pays
for
that.
They
want
that
for
free,
yeah.
D
D
D
B
C
C
Clapped
together
here,
yeah
we
it
works,
you
know
it
looks
cool
and
everything
it
makes
great
art.
You
know
you
know,
but
that's
you
know,
and
it
works.
It's
like
okay.
This
is
neat
and
the
you
know
the
so.
The
traditional
sort
of
you
know
you
know
there's
vertical
and
horizontal,
you
know,
so
you
go
this
way
and
you
go
this
way.
C
A
B
C
C
Well,
you
know,
being
in
a
in
a
fairly
tightly
packed
neighborhood.
You
really
have
to
start
worrying
about
how
how
loud
is
it,
and
especially
with
satnag
stations?
That
has
been
a
recurring
issue.
So
if
you
put
your
satanog
station
in
in
a
regular,
suburban
neighborhood-
and
it
tends
to
be
a
little
loud
and
it's
running
all
night
long,
your
neighbors
are
going
to
come.
Ask
you
what
exactly
is
going
on
here
and
that
that
three
o'clock
in
the
morning
you're
right
outside
their
window,
is
not
great,
so
sat
nags
does
not.
C
It
just
assumes
that
you're
available
24
7
and
it
will
schedule
your
station
for
tracking
stuff
all
over
the
sky.
You
know
and
a
loud
station
can
be
loud.
You
know
so
so
that's
a
consideration
that
we
we've
learned
about.
You
know
when
you're
looking
at
like
a
a
nice
big
yard,
you
know
what
I
would
consider
growing
up
to
be
a
normal
yard
like
an
acre
or
so
you
can
have
a
loud
thing
out
there
and
nobody
minds
much
right.
