B
Yes,
so
recording
here
so
meeting
with
Matt
from
the
tech
portrayed
project,
so
Marcin
here,
reporting
on
a
state
of
the
open
source,
filament
maker,
with
P
et
so
we're
discussing
how
to
move
forward
on
the
open
source
version
of
the
PE
T
filmmaker
from
tech
portrayed,
where
Matt's
team
has
agreed
to
open
source,
that's
or
discussing
how
to
make
that
happen,
most
strategically
so
Matt.
What
are
some
of
your
questions
that
I
can
address.
A
When
I
guess,
I'll
just
make
sure
that
we're
we're
having
good
impact
with
our
work
instead
of
just
posting
it
out
on
the
corner,
get
up
and
well
having
it
sit
there
or
I
guess
the
other
thing.
That
kind
of
you
know
we
hatched
through
a
little
while
we
had
done
a
bunch
of
work
that
another
group
was,
you
know,
kind
of
implying
they
had
done,
which
was
kind
of
frustrating
to
see,
especially
in
the
world
where
you
know,
there's
a
lot
of
competition
for
funding.
B
Yes,
so
I
think
we
can
start
this,
this
discussion
with
documentation
how
how
to
document
this
effectively.
So,
for
example,
if
you,
if
you
were
keeping
a
log
or
public
presence
on
this,
no
one
could
even
begin
to
make
that
claim
right.
Naturally,
so
so
it's
about
working,
transparently
and
public
out
there.
That's
that's
a
way
to
to
protect
your
work.
So,
let's,
let's
take
some
notes
here
so.
A
B
B
A
A
B
A
B
A
Not
even
know
I
mean
I,
don't
know,
I
think.
Basically,
like
things
didn't
really
turn
out
the
way
we
have
anticipated
yeah,
it's
just
like.
Oh,
so
that's
what
we're
gonna
get.
You
know
it
was
more
like
I
think
that
kind
of
led
us
to
like
okay.
Well,
maybe
we
should
just
you
know,
wait
until
everything's
totally
ready
to
go
and
then
just
say:
okay,
here's
what
we
have,
here's,
what
we
have
done,
no
I
think
it
was
like
concerned
about
getting.
You
know,
beat
to
the
punch
line
in
the
last
few
years,
birds,
yeah.
A
A
You
know
definitely
linked
to
going
out
and
searching
for
funds,
and
you
know
if
you
can't
you
can't.
You
know
if,
basically
when,
when
groups
say
well,
you've
been
working
on
this
for
a
long
time.
What
impact
have
you
had
and
you're
like
God,
you
know
how
do
we
make
sure
that
that
we
can
demonstrate
that
we're
having
that
impact,
you
know
so
even
other.
C
A
The
work
and
having
impact
them
to
me,
it
just
seems
like
well,
we
can
just
point
you
know
to
what
we're
doing
into
what
other
groups
are
doing
and
say:
yeah
we've
had,
you
know,
active,
multiple,
no
ways.
One
way
is
by
allowing
other
groups
to
have
impact,
but
I,
don't
know
what
you're
kind
of
feel
as
long
I'm
sure
you've
kind
of
gone
through
similar
sort
of.
B
B
B
B
A
I
think
when
I
get
back
to
the
u.s.
so
far
as
we've
been
talking
right,
you
know
with
everybody
on
the
team.
A
big
part
of
my
focus
is
gonna,
be
getting
this
documentation
and
so
on.
But
so
like
one
of
the
things
that
everybody's
been
saying
is
hey,
let's
get
it
up
and
out
there,
but
it
seems
like
it's
more
than
just
the
documentation
like
getting
our
story
out
there.
You
know
and
all
the
calms
side
of
everything
as
well
right.
A
B
A
B
B
B
A
A
B
A
B
A
B
Uh-Huh
you're
getting
ready
ready
to
build
your
own
pie
phone,
though
you
know
raspberry
pie,
telephone,
okay,
anyway,
I'm
thinking
about
it,
yeah,
that's
the
setup
right
now,
wow,
that's
that's
a
little
cluster
of!
Are
you
able
to
make
these
replicable,
just
like
you
show
in
this
picture,
like
pretty
replicable
to
that
to
that
level?
As
far
as
the
printers.
B
A
A
They're,
like
we,
we've
been
working
on
them
being
able
to
make
filament
nice
that
mark
just
kind
of
has
been
on
hold
I,
think
we
kind
of
jumped
on
it.
Thinking
we'd
get
through
the
filament
process
a
lot
faster
than
we
did
so
now
that
you
know
now
that
we're
starting
yep,
recycle
filament,
like
all
that
kind
of
stuffs,
gonna
gonna,
coming
back
up
yep.
A
A
A
B
A
A
A
A
So
I
would
I
would
think
like
in
terms
of
you
know
again-
and
this
is
just
speaking
from
the
perspective
more
I-
could
do
it
much
faster
if
I
had
stayed
got
to
our
nice
free
cab
designs
that
release
you
know,
but
I
mean
I,
don't
know
so.
I
haven't
worked
with
spri
Kent,
for
when
we
really
on
when
we
did.
The
pre-cut
out
is
actually
writing
Python
scripts.
A
A
A
A
Focused
on
like
using
absolutely
as
much
waste
as
possible,
which,
while
it
made
the
printer
very
low
cost,
was
you
know
like
I
mean
it
was
set
up,
so
you
could
use
like
on
the
say
hello
say
on
the
y-axis.
You
could
use
a
10
millimeter
food
rod
on
the
6
millimeter
smooth
rod.
The
same
access
would
adjust
all
of
the
3d
printed
parts
to
make
all
work.
A
You
just
go,
get
a
bunch
of
scrapping
and
the
free
cab
with
little
rest,
but
it
just
became
really
cumbersome
in
terms
of
reduction
had
to
be
super
super
organized,
or
else
you
end
up
with
3d
parts
that
didn't
match
the
printer.
You
thought
you
were
building
the
sort
of
thing
so
yeah
I
mean
it
had
some
mechanical
issues.
A
B
Now
we're
basically
I
mean
right
now,
most
of
our
revenue
is
coming
from
the
workshop
model.
So
basically
we
do
extreme
builds
over
a
weekend.
We
build
a
machine
of
some
sort,
so
the
idea
here
would
be
that
we
streamline
and
document
everything
and
create
it
into
an
event
experience
where
people
can
actually
be
building
these
and
I
think
that's
a
huge
scaleable
revenue
model
and
that's
that's.
What
we're
working
on
developing
basically
create
a
franchise,
a
franchise
model
where
we're
training
the
people
who
are
running
these
workshops.
B
We
can
only
run
so
many
of
them
right
now.
I've
been
running
one,
maybe
every
month
or
every
other
month,
because
it's
a
lot
of
work,
but
once
you
refine
it,
you
can
make
it
a
regular
product
offering
and
refine
the
publicity
around
that
such
that
you
have
a
viable
enterprise,
and
then
you
can
be
teaching
that
to
your
people,
whether
it's
it's
your
digital
blacksmiths
or
another
kind
of
immersion
program
like
for
us
right
now.
B
We're
gonna
do
a
much
deeper
immersion
program
where
the
people
who
come
to
us
learn
to
do
both
like
the
3d
printers,
the
micro
tractors.
Cnc
torch
tables
and
other
products,
and
the
micro
house
and
CD
CD
go
home
and
aquaponic
greenhouse
like
we're.
Gonna
teach
people
through
an
immersion
program
how
to
do
the
whole
thing.
So
there's
revenue
from
education
and
from
running
workshops
so.
C
B
Think
of
it
as
a
University
of
Maine
University
is
a
well
proven
business
model
right
teaching.
So
that's
that's
the
direction
we're
going
now,
we're
being
very
deliberate
about
not
getting
into
manufacturing
we're,
not
a
manufacturing
organization
work,
we're
an
educational
organization.
We
also
happen
to
produce
things,
but
that
comes
through
education
and
that's
a
totally
different
ballgame.
It's
about
replication.
It's
about
teaching
an
open
source
as
opposed
to
you,
go
out
there
and
just
make
dumb
factory
workers
right,
we're
creating
smart
producers.
B
So
we
focus
on
the
education
aspect
in
order
to
transition
to
a
different
kind
of
economy
where
it's
not
about
just
consumerism,
but
it's
about
people
really
synergistically
working
with
with
production
to
have
that
happen
in
micro,
factories
and
local
communities.
So
so
the
idea
here
is
a
micro
fact.
I
mean
we
could
collaborate
on
the
open
source
micro
factory
model,
where
I
think
the
the
film
and
maker
and
the
3d
printer
can
be
a
core
to
that
kind
of
operation.
I
mean
you
can
do
a
lot
of
different
products
that
you
can
talk
about.
B
A
B
Yep,
that's
right,
so
it's
a
very
exciting
thing
and
I
would
definitely
suggest
I
mean
pretty
much
claiming
a
space
space.
Of
that
you
know.
Educate
people
about
I
mean
claim
first
of
all,
start
publicizing
this
stuff
start.
You
know
start
documenting
all
that
you
have
done,
and
then
the
history
will
kind
of
write
itself
around
that
and
and
by
by
going
open-source.
If
you
use
a
license
like
creative
commons,
share-alike
you're
saying
everyone
also
has
to
keep
the
work
open.
B
So
it
also
helps
you
you're,
not
just
throwing
it
out
for
nothing,
but
the
improvements
that
you
get
from
the
community
also
come
back
to
you
and
you
can
improve
your
own
business
model
with
that.
That's
the
idea,
yeah
yeah,
so
that's
I,
mean
that's
the
nutshell
of
this
revenue
model
that
I
think
I.
Think
it's
huge
I
mean
that's
that's
what
we're
pursuing.
We
don't
have
the
results
as
far
as
having
taught
and
scaled
operation,
yet
pretty
much
myself
and
Katharina
my
partner
here,
who
does
the
open
to
building
institute?
B
That's
pretty
much
a
spin-off
of
open
source
ecology
in
terms
of
it
uses
a
lot
of
its
rapid,
build
techniques
plus
machinery.
But
beyond
that,
we
have
to
distribute
this
work
to
others.
For
this
to
this
movement
to
grow
so
and
that's
where
the
open
source
comes
in
I.
Think
anybody
who
save
the
world
so-called
or
changed
the
world
I
mean
you
got
to
be
open
source
in
order
to
scale
it
so
that
the
uptake
happens
both
from
independent
players
and
also
from
a
very
deliberate
program
of
making
it
happen.
B
Because
what
you'll
see
is
that
it's
hard
to
make
it
happen?
You
really
have
to
nurture
that
process
in
order
to
facilitate
others.
Doing
that,
like,
for
example,
with
me
and
a
brick
press
I
thought
you
know,
people
will
be
starting
businesses
left
and
right
with
a
brick
press
that
we've
developed,
that
now
costs
us
five
thousand
and
materials
four
and
a
competitor
costs.
Fifty
two
thousand
dollars
right,
I
thought
as
soon
as
we
get
that
out.
B
You
know
people
will
be
starting
hundreds
of
businesses
around
it,
but
it's
not
it's
like
like
there's,
not
a
lot
of
entrepreneurs.
True
entrepreneurs
out
there
so
I
think
it's
very
useful
that
we
nurture
those
kinds
of
people
as
much
as
possible
to
help
that
and
create
the
people
who
are
future
developers
like
from
the
workshops.
We
find
a
lot
of
people
who
are
developers.
Word
gets
out
like
that,
so
I
just
want
to
keep
doing
more
workshops
and
and
hopefully,
by
next
year,
I
have
a
few
people
that
are
also
doing
that.
B
A
A
B
Absolutely
I
mean
I
think
you
can
run
workshop.
We're
I
mean
if
this
is
a
serious
product
like
I
mean
after
all,
you
have
to
have
a
product.
If
it's
a
serious
product
I
mean
it's
highly
relevant
to
the
United
States,
so
you
can
use
that
as
a
way
to
fund
the
further
work
like,
for
example,
through
some
of
that
work,
you
can
attract
interest.
You
know
you
raise
the
raise
the
interest
in
America
and
people
find
out
about
it
and
and
people
love
supporting
Africa
projects.
B
You
know
so
they'll
be
like
oh
yeah
fund
this
for
Africa
and
that's
how
you'll
find
more
more
interest
in
more
people,
but
in
Africa
I
mean
it'll,
be
training.
The
digital
blacksmiths
here
would
be
for
others
who
just
want
to
have
this
thing
and
start
their
own
businesses
too.
I
mean
it
really.
The
visual
blacksmith
applies
to
Africa
as
much
as
America
I.
Think
I
mean.
A
C
A
A
B
A
So
I
think
some
next
steps
for
us
know
in
terms
of
say,
like
the
document
you
got
going,
there
is
also
you
know,
especially
if
you
take
a
look
at
what
we
have
online.
That's
probably
us
that
we
don't
have
in
terms
of
our
documentation.
We
don't
have
a
structure
that
you
know,
I
mean
even
I
would
say
for
me,
like
even
say
version
you.
C
B
From
I
mean
yeah,
I
mean
the
wiki.
The
world's
largest
successful
project
is
a
wiki,
that's
Wikipedia
I
mean
start
a
wiki,
a
wiki
has
actual
versioning
you
actually
conversion
files
on
the
wiki
itself,
like
we
use
media
wiki.
If
you
upload
a
file,
the
the
old
file
is
kept
there
and
you
see
the
whole
revision
history,
so
I
mean
start
with
a
wiki
like
media,
wiki,
I
think
that's
a
great
tool.
Anyone
can
edit.
C
B
A
B
A
A
B
Yes,
I
mean
we
want
to,
we
want
to
use
it,
I
mean
for
us.
We
want
to
we
want
plan,
we
want
low-cost
film
and
we're
working
with
alignment,
film
and
extruder
right
now
we're
we
have
done
a
partial
prototype
of
that.
So
we're
gonna
continue
with
that
as
well.
That's
for
abs,
so
it'll
be
maybe
simpler
or
easier,
but
you
guys
have
the
high
tech
stuff
so
I
mean
that
would
be
extremely
useful
for
us
and
once
again
to
do
the
work
shops
where
we
run
a
workshop.
B
B
A
A
A
A
A
B
A
A
A
B
B
A
A
C
B
B
So
that's
open
source
ecology
is
kind
of
like
not
just
appropriate
technology
for
the
developing
countries,
but
in
general
yeah.
That's
just
yeah
anyway.
I
mean
that
a
Pepita
is
a
good
place.
Our
wiki
is
a
good
place.
I
mean
until
you
get
your
own
by
mean
you
can
just
set
up,
presents
on
open
and
we'd
love
to
have
that.
A
B
A
B
I
mean
just
to
get
your
feet
in
the
water
here,
I
mean
think
about
okay.
What
state
of
development
is
the
film
and
maker
in
and
the
width
sensor
to
make
good
use
of
different
filament
and
then
I
mean,
let's
think
about
when
we
could
organize
a
a
build
workshop.
You
know
where
we
invite
a
bunch
of
people
and
that's
as
a
revenue-generating
opera.
A
A
B
B
B
A
A
B
A
A
So
I
think
the
issue
is
like
finding
finding
something
that
will
work
with
one
of
those
smaller
lower-cost
Arduino.
Otherwise,
what
happens
is
like
the
cost
of
everything
big
sensor.
That's
really
high
resolution.
There
really
fast
maker
across
us
or
with
a
lot
of
memory,
faces
just
go
up,
but
maybe
not
you
know.

A
A
B
A
No
I've
been
kind
of
getting
my
toes,
wet
and
a
whole
bunch
of
different
don'ts,
but
I
am
definitely
not
an
expert
in
any
of
them.
Uh-Huh,
basically
they'll
say

If
you
look
at
the
extruder,
the
circuit
isn't
long
breadboard
still
like
I
just
test
them
half
the
time
to
learn
how
to
draw
that
up
and

whereas
I
know
their
million
people
out
there.
That
can
do
that
with
their
eyes
closed
yeah.
So
definitely
there
are
a
lot.
