Happening
on
the
D
3d
3d
printer
in
Ohio,
and
maybe
some
other
things
so,
let's
see
so
quickly
getting
right
right
into
the
bio
digester
work.
It
looks
like
somebody
has
produced
an
interest
very
interesting,
a
badge
for
ourselves,
I
cracked
up
when
I
saw
that,
but
the
by
that
just
is
pretty
much.
We
started
it.
We
started
feeding
it
with
digestate
from
the
sink
we're
connecting
the
toilet
to
that,
and
then
your
futures,
so
in
progress
happening
with
quite
a
complex
system,
takes
a
bit
of
time
tip
to
make
it
work.
A
A
Okay:
let's
talk
about
the
open
source,
Leadership
Summit,
real,
real,
quick
update
on
that
it
was
a
very
interesting,
interesting
meeting.
My
comments
from
it
are
is:
are
that
I
remember
a
few
years
ago?
It
used
to
be
the
rivalry
between
open
source
and
closed
source,
and
the
clear
case
right
now
is
that
open
source
has
one
I
mean
every
just
about
everything,
including
noun,
artificial
intelligence,
machine
learning.
It's
all
it's
all
going
open
source
in
the
in
the
conference
itself.
A
A
lot
of
those
peoples
are
Google
Microsoft,
and
it's
kind
of
like
there's,
also
the
critique
of
that
that
the
kind
of
the
Libre
aspect
of
it
has
been
lost,
and
it's
just
business
because
because
it
works,
open-source
works,
it's
recognized
as
a
as
an
effective
development
methodology
and
everyone's
using
it
so
hands
down
it.
Linux
has,
you
can
say
in
some
way
won
the
battle,
but
in
some
way
it's
it's
kind
of
lost
the
war
in
some
way.
A
A
The
that
85mm
of
the
world's
richest
people
have
as
much
wealth
as
3.5
billion
at
the
bottom
of
the
pyramid,
and
let's
take
a
look
at
that,
because
all
kind
of
like
all
the
discussion
out
there
in
public
seems
to
be
that
wealth
is
still
a
huge,
huge
bad
issue.
But
if
you
look
at
in
the
next
in
this
slide,
here,
look
at
the
Gini
Gini
coefficient.
So
that
is
the
Google.
It
look
it
up
on
Wikipedia,
that's
a
measurement
of
the
distribution
of
wealth,
0
being
let's
see,
Gini
coefficient.
A
What
is
it
0
being
perfect
distribution,
meaning
that
each
person
as
much
wealth
as
the
next
person,
whereas
one
one
person
in
a
world,
has
all
the
wealth
in
the
world?
Well,
so,
since
1800
that
that
Gini
coefficient
has
been
like
about
3
or
0
point
4
or
so
around
1988,
it
was
at
around
point
six
or
seven
point
six
or
point
seven.
But
if
you
look
at
1988,
if
you
this
is
actual
data,
you
see
the
Gini
coefficient
going
down,
meaning
towards
better
distribution
of
wealth.
Well,
that
is
good
news.
A
It's
like
that's
the
ultimate
data,
so
it's
showing
the
coincidence
of
the
information,
age
and
distribution
of
wealth.
Actually
getting
better.
Is
that
so,
even
though,
in
the
bottom
right
hand
graph
here
still
that
number
of
the
60
you
know
this
picture,
85
of
the
world's
richest
individuals,
that's
going
down
and
went
down
to
62
and
apparently
in
2017,
it
was
down
to
8
and
a
number
of
billionaires
is
increasing
like
mad
it's.
A
This
is
the
graph
here,
there's
around
2000
billionaires,
but
when
we
talk
about
billionaires
like
in
the
90s
1990s,
they
used
to
be
like
5
billion,
and
now
the
richest
people
are
like
50
billion.
So,
even
with
that,
if
the
Gini
coefficient
is
saying
that
that
the
Gini
coefficient
is
going
down,
if
it's
going
down,
distribution
is
happening.
In
other
words,
the
pie
is
growing
for
everybody,
which
is
good,
that's
awesome,
but
at
the
same
time
open
hardware
doesn't
exist,
and
that's
that
was
kind
of
talking
about
that.
How
do
you
do
that?
A
So
it's
about
internalizing
the
history
of
evolution,
historical
evolution
of
economy,
is
about
internalizing
different
aspects
into
the
economy.
Like
slavery
has
been
a
cop
abolished
in
1865,
Linux
rose
up
in
the
1990s
1999.
The
concept
of
natural
capitalism
has
tried
to
push
to
the
mainstream
that
earn
internalization
of
social
and
environmental
issues,
and,
to
me,
like
the
last
frontier
of
internalizing,
the
performance
of
an
economy
is
the
distribution
question.
A
The
distribution
issue
is
pretty
much
unaccounted
for
in
our
economic,
accounting
and
environmentalism,
social
issues
they're
starting
to
come
into
the
system,
but
that's
it's
interesting,
and
but
you
know
one
way,
I
was
somewhat
disappointed
that
yeah,
like
mixed
feelings
from
this
conference
like
in
one
side,
it's
it's,
you
know
open
source
is
dominating,
but
on
the
other
side.
Well,
for
one
open
hardware
is
like
really
unknown
still
like
the.
We
are
basically
in
a
competitive
kind
of
warfare,
economy
and
so
to
say
so
it
kind
of
had
mixed
feelings,
but
definitely
you
know
it's.
A
The
case
is
to
be
made
for
open
hardware,
economics
and
the
main
three
points
that
I
pointed
out.
So
at
the
end
of
my
presentation,
I
talked
about
like
the
the
milestones
that
we
have
achieved
as
far
as
showing
the
the
workshops
happening
like
when
we
build
the
sadhika
home
we
make
like
running.
This
is
an
educational
event.
A
A
The
cost
of
industry
standards
like
have
a
turnkey
package,
where
a
client
pays
the
total
of
like
set
about
seventy
thousand
dollars
for
a
turnkey
product
compared
to
at
least
like
where
we
are
you'd,
probably
pay
like
a
hundred
sixty
thousand
around
for
a
house
like
that,
but
typically
houses
like
the
city
go
home,
I
mean
they'd,
be
more
like
two
hundred
fifty
thousand
or
something
so
definitely
like.
There's
a
cost
advantage,
so
we
think
the
market
is
there
and
then
on
things
like
the
brick
press.
A
When
we
build
a
brick
press
and
sell
it,
we
can
make
ten
thousand
bucks
in
a
three
day
workshop
five
thousand
in
tuition,
five
thousand
net
in
the
product
sell.
So
there's
definitely
a
revenue
model
there
for
the
3d
printer.
When
we
run
the
workshop
and
twelve
people
show
up,
we
make
thirty
six
hundred
bucks.
A
So
there's
all
these
possibilities
to
to
generate
revenue
from
this
workshop
based
production
model,
and
that's
that's
where
we're
going
for
this
September
I'm,
still
planning
on
we're
planning
on
the
immersion
program
where
people
would
actually
do
this
for
a
real
job.
You
know
this
is
this
is
what
you
do
for
a
living,
because
there's
there's
revenue
in
this
and,
of
course,
there's
a
lot
of
work
to
get
that.
Do
that,
but
that's
that's
kind
of
my
summary
of
the
what
I
talked
about.
C
A
A
A
C
D
C
A
B
A
Okay,
ten
megabytes,
okay,
so
here's
here's
one
thing:
your
your
files
getting
pretty
fat,
so
so
we've
been
through
this
actually
in
the
last
iteration.
But
what
you
want
to
do
is
you
use
the
simplified
files,
so
there's
a
whole
whole
deal.
We
did
about
file
simplification,
where,
when
you
use
the
axes
in
all
the
parts
you
wanna,
you
want
to
use
the
simple
files
and
where,
where
is
that?
Do
you
know
where
have
you
run
into
any
of
that.
C
A
Let's
see
well
I
know
what
happened
was,
for
example,
for
the
d
3d
CNC
circuit
mill
yeah
that
worked
really
well
well,
where
we
did
the
design
from
scratch
using
the
simplified
model.
Let's
see,
let's
see
what
we
can
learn
from
that.
Can
you
paste,
let's
see
I'm
trying
to
orient
myself
where
the
simple
files
are.
Do
we
recall
where
the
simple
files
are
there?
They
are,
for
example,
single
Y
ax
right,
because
this
is
where
we
really
want
to
have
this
workbench
that
Rousillon
is
working
on,
but
let's
see.
C
A
A
A
C
A
C
C
A
C
C
C
C
C
A
And
in
the
circuit
mill,
I
would
actually
suggest
using
those
they
are
dimensionally
correct
and
they
have
all
the
critical
features
like
that,
the
ones
that
are
important
and
relevant
to
what
you're
gonna
do
like
the
bulk
holes
like
on
the
edge
the
nut
catchers
so,
and
look
at
that,
if
you
click
on
one
of
them,
they
are
this
one's
like
19
k,
the
one
I
yeah,
which
means
that
you're
gonna
be
just
able
to
really
do
it
fast.
Let's
see,
though,.
E
C
C
C
B
B
A
C
C
B
B
B
B
A
I
think
yeah.
The
only
thing
you
want
to
add
then,
is
just
from
the
d3d
cnc
circuit
mill.
Add
those
because
those
are
the
the
smallest
files
available.
I
mean
I
thought
we
did
that
at
another
place,
but
no,
no,
the
the
ones
that
DVD
integration
are
more
like
on
a
megabyte
size.
The
one
understands
you,
sir
c'mon
yeah,
that's
what
you
want
to
use.
That's
the
that's!
The
ultimate
now
I'm
just
curious,
where
those.
B
C
A
I
mean
the
thing
we
want
to
do
is
is
keep
track
off
the
development
template
is
supposed
to
be
the
place
to
organize
everything,
build,
buy,
build
and,
as
you
see
as
we
just
keep
blasting
through
one
build
after
another,
and
things
tend
to
kind
of
collapse,
so
yeah,
but
the
3d
landing
page,
that's
good.
If
we
can
make
that
work,
so
I
added
that
2d
3d
d,
3d
page
as
a
note
on
top
CD
three
language
for
off
effort
to
organize
the
latest,
build.
A
C
A
A
E
C
C
A
Right,
it's
right
below
there,
okay,
okay!
So
we
got
that
and
it's
modified
it's
the
modified
version
with
the
larger
sensor
holder,
which
those
those
STL
files
are
not
anywhere
that
you
have
to
I
think
export
it.
So
when
you
put
all
your
assets
together,
you
have
to
generate
the
STL
file
where's
the
STL
file
here.
C
C
C
A
C
C
C
C
A
C
C
C
A
It
might
take
take
a
little
bit
yeah,
let's
just
keep
cranking
on
it.
Yeah
I'll
be
probably
getting
back
to
the
I.
Have
the
build
with
the
metal
frame
here,
which,
which
is
18
point?
Oh
one,
so
that's
that's!
The
one
I'm
working
on
you've
got
18
point
o2,
but
yeah
I'm
getting
I
just
ordered
that
that
big
sensor,
you
started
a
couple
of
days
ago
yeah,
but
it's
gonna
take
like
twelve
days
or
something
twelve
day.
Shipping.
C
A
C
A
D
C
C
A
C
A
E
A
C
A
A
Yeah,
okay,
so
yeah,
we
can
call
that
make
it
a
short
meeting
this
time
around
and
continue
back
we'll
touch
back
in
next
week,
see
where
we
are
at
that
time
and
go
from
there
so
yeah,
okay,
all
right
guys!
Well
thanks
a
lot
we'll
just
keep
it
here
short
meeting
and
we'll
see
you
guys
next
week,
Tuesday
2:00
p.m.
okay.
