A
Recording
recording
we're
going
to
go
for
about
an
hour
with
respect
to
the
introduction
to
today's
day,
so
the
apprenticeship
involves
there's
the
design
sessions
and
then
there's
the
workshop
sessions
and
then
saturdays.
What
we
do
is
think
more
heavily
about
how
we
involve
the
whole
global
community
in
development.
A
The
big
problem
that
open
source
hardware
is
still
trying
to
solve
is
people
showing
up?
How
do
you
get
a
lot
of
people
to
contribute
and
continue
contributing,
and
the
answer
to
that
is
ultimately
has
to
be
livelihood,
and
that's
that's
why
we're
shifting
a
lot
from
so-called
project
development
to
product
development
so
that
people
can
get
meaningful
livelihoods
out
of
this
kind
of
work?
A
Now,
over
the
years
that
we've
done
kickstarters
we've
done
some
crowdfunding.
I
initially
started
on
on
doing
fundraising
by
after
I
ran
out
of
money
out
here
on
the
land.
With
a
little
bit
of
savings
I
had
from
college.
I
started
crowdfunding
and
basically
put
up
crowdfunding
web
baskets
on
the
internet
and
found
that
wow
people
are
willing
to
contribute
to
this.
I
was
publishing
a
lot
of
videos
with
the
early
work.
A
How
we
settled
on
the
land
and
how
we
started,
building
the
machines
and
pretty
soon
we
got
to
the
world
stage
and
and
today
just
continuing
a
bootstrap
method
and
deliberately
doing
it
in
a
crowd-sourced
way,
so
that
it's
replicable
so
we're
not
we're
not
relying
on
foundation
funding
to
to
do
this.
We
did
get
some
foundation
funding
around
the
ted
talk
time.
I
also
became
a
shuttleworth
fellow,
so
some
money
from
that,
but
by
and
large,
in
order
to
make
it
largely
replicable
we
want
to.
A
A
We've
done
the
crowdfunding
and
various
various
other
methods,
hackathons
other
things,
and
through
all
these
times,
we've
done
the
development
team,
the
remote
development
team
and
and
on-site
events,
but
at
all
times
it's
the
amount
of
people
you
can
get
to
show
up
is
is
limited,
you're
talking
about
volunteer
time
and
once
again
it
has
to
get
into.
Are
you
doing
something
for
a
living,
or
is
this
just
a
pastime,
something
that
you
can
only
do
when
you
have
free
time?
A
I
want
to
bring
up
the
concept
of
an
incentive
challenge
so
that
that
is
what
we're
actually
planning
right
now
and
we're
actually
allocating
100k
to
that
and
that's
actually,
where
is
that
coming
from
that's
actually
coming
from
all
the
bitcoin
donations
that
we
can
cash
in
on,
but
we're
planning
right
now
to
allocate
100k
to
an
incentive
challenge.
A
So
if
you,
google,
that
it
didn't
mention
a
lot
about
the
concept
of
the
incentive
challenge,
and
I
think
that
is
a
model
that
can
work
so
basically,
you
put
up
a
prize
for
some
development
and
then
you
you
reap
the
benefits
of
that
so,
but
also
structuring
that
and
making
that
work
is
the
challenge.
How
do
you
do
it,
and
also,
how
do
you
do
it
collaboratively?
Because
if
we,
if
you
look
at
a
lot
of
the
challenges
out
there,
everything
is
pretty
much
proprietary.
The
results
are
proprietary.
A
There
are
some
open
things,
but
when
you
do
an
incentive
challenge
today,
typically
it's
that
the
result
is
is
proprietary.
I
mean
look
at
the
platform
called
hero
x
and
we're
actually
planning
to
use
hero
x.
It's
a
well-known
platform.
It's
an
offshoot
of
the
of
the
xprize,
which
is
a
very
well
known,
global
incentive
challenge.
A
A
So
what
do
we
do?
We
start
with
with
a
problem
that
we
think
is,
is
worth
solving
and
then
go
about
it,
and
the
psychology
of
the
incentive
challenge
is
such
that
historically,
a
lot
of
these
incentive
challenges
have
been
such
that
the
amount
of
effort
people
put
in
is
much
greater
than
the
actual
prize,
and
especially
the
collective
effort
collectively.
A
A
People
do
want
to
do,
spend
extraordinary
amount
of
time
on
these
kinds
of
challenges.
And
the
thing
is
it's
like
a
game.
It's
a
it's!
The
human
psychology
people
are
some
somewhat
competing
against
each
other
and
and
that
kind
of
psychology
makes
people
put
in
much
more
effort
than
a
reward
price.
So
even
you
know
when,
when
somebody
want
wins
whatever
like
the
car
challenge
like
say,
wikispeed
entered
the
car
challenge
to
get
a
hundred
mile
per
gallon
car.
A
They
put
x
effort
the
reward.
A
Well,
I'm
not
sure
about
wikis,
because
wikispeed
did
it
on
a
cheap,
but
but
many
many
teams
would
put
in
tons
of
money.
Like
if
their
reward
is
one
million
they'd
put
in
like
five
million
you
know
or
whatever
so
and
of
course
collectively
it
adds
up
to
much
more
than
say
that
one
company
put
in
say
5
million
to
develop
this
entry
for
a
prize.
Imagine
what
happens
when
you
do
that
collectively.
A
A
A
Now,
it's
a
it's
a
problem:
it's
not
super
hard,
but
definitely
there's
there's
collaboration
needed
in
order
to
get
low-cost
equipment
and
techniques
and
everything
around
that
that
makes
it
feasible
so
right
now
the
idea
is:
we've
got
a
large
printer.
The
property
of
that
is.
It
has
to
have
an
enclose
a
high
temperature
build
chamber
because
without
such
a
thing,
you're
reduced
to
printing,
just
with
a
few
plastics
like
pla
tpu,
which
is
rubber.
Some
of
the
rubber
plastics
like
abs.
A
Even
I
mean
you
can't
print
abs
meaningfully
without
a
heated
chamber,
even
layers
would
delaminate.
If
part
of
a
print
is
cold,
so
so
3d
printing
is
depositing
just
just
for
the
plastic
version,
depositing
plastic,
the
heated
chamber
is
much
needed
when,
because
a
lot
of
plastics
are
so
hard
to
print
with
that,
if
you
don't
have
a
very
highly
controlled
environment,
they
simply
delaminate.
If
it's
too
cold
the
layers
just
separate
and
it
doesn't
work
so
right
now
you
cannot
print
with
the
most
common
plastics
like
like
polyethylene
polypropylene,
like
even
abs.
A
You
can
do
a
little
bit
right
next
to
the
heated
bed.
Once
you
come
off
like
say,
you
try
to
print
a
very
tall
thing,
no
way
without
a
heated
chamber,
so
completely
limited
without
that,
and
we
have
to
do
that
and
there's
no
single
open
source
hot
chamber
out
there
there's
been
a
prototype
done,
for
example,
by
the
most
people
of
michigan
tech.
They
did
a
prototype
of
a
of
a
printer
that
does
have
a
heated
chamber,
but
it's
not
designed
to
the
point
where
you
can
do
it,
continuous
and
and
scalable.
A
A
A
A
So
this
is
talking
about
serious,
serious
product
now
before
you
get
to
this
this
printing,
if
you're
gonna
go
from
trash
because
the
deal
is
one
kilo
of
filament
is
about
twenty
dollars
right.
So
that
means,
if
you
were
to
print
a
house
which
weighs
20
tons.
So
that's
40,
000
well,
20
tons
is
what
20
000
kilos
times
20.
A
well
right,
so
20
per
kilo.
If
you
were
to
3d
print
the
house
out
of
plastic-
or
you
can
do
like
plastic
composites
with
wood
like
wood
dust
sawdust,
which
makes
it
look
like
actually,
your
printing
smells
like
like
wood
and
looks
like
wood,
but
okay,
20
tons.
A
What's
that
20
000
times
20
400
000
dollars
for
printing,
that's
the
one
1
000
square
foot,
cdca
home!
There
would
be
about
ten
tons
of
equivalent
lumber
weight
in
there.
Now
that
we
could
displace
and
pretty
much
get
most
of
the
structure
and
everything
out
of
waste.
But
four
hundred
thousand
dollars
is
not
doable.
That's
weird!
We
want
to
get
to
more
like
four
thousand
dollars,
maybe
like
a
hundred
x
better
than
that
and
that's
you
have
to
go
to
the
waste
stream
to
do
that.
So
waste
stream
plastic.
A
A
20
per
kilogram
to
like
maybe
10
or
20
cents
per
kilogram,
so
a
factor
of
a
hundred
x
if
you
go
to
recycling.
So
that's
that's
an
important
point,
but
you
have
to
have
the
infrastructure
to
do
that,
so
you
need
a
shredder
and
you
need
then
a
plastic
filament
maker,
those
things
we
have
built
already
here.
We
we
know
something
about
that
and
the
challenge
is
to
reduce
the
cost
of
this
entire
system.
A
A
A
I
think
it's.
I
think
the
problem
is
such
that
it
would
require
a
number
of
people
to
do
it,
especially
if
you're
going
to
say
we're
going
to
use
this
challenge
and
a
six
month,
probably
like
a
six
month,
development
period,
six
to
one
year,
leverage
a
lot
of
contributions,
something
that
solvable
pretty
much
readily,
but
it's
more
than
any
single
person
can
do
or
like
any
single
company
can
do
it's
just
too
many
things
to
make
it
work.
I
mean
product
r
d
is
intensive.
It's
a
lot
of
prototyping.
A
So
that's
so
we
want
to
throw
up
an
incentive
challenge,
that's
impossible
by
one
person
and
therefore
you
you
demand
that
collaboration
is
the
way
to
do
it.
So
you
cannot
have
say
a
hundred
teams.
Okay,
so
say
at
the
price
point
of
like
a
hundred
thousand
dollar
incentive
challenge
the
way
it
goes.
Typically,
it's
like
about
a
thousand
people
show
up
or
so
thousand
teams.
A
A
I
looked
for
that
and
I
was
blown
away
to
see
that
all
the
rules,
as
I
mentioned
other
days,
all
the
rules
are,
if
you
borrow
from
others,
you're
cheating
and
you're
disqualified,
which
is
nonsense.
That's
that's
absolutely
ridiculous.
So
we
have
a
value
proposition.
Let's
say
we're
collaborating
here
great!
So
that's,
I
think,
that's
a
good
start
and
als,
but
a
lot
of
this.
A
It's
really
about
creating
collaborative
culture
right,
so
we're
doing
something
a
little
different,
and
I
think
that
is
the
value
we
can
provide
to
the
world
because,
as
we
do,
this
people
will
look
at
this
and-
and
we
want
to
set
an
example
for
more
people
to
follow
this,
because
why
shouldn't
everything
be
collaborative
like
that,
even
the
incentive
challenges
which
you
think
would
be
for
the
common
good.
It's
like
it's
so
obvious.
A
So
that's
the
way
I
see
it
so
on
a
technical
front,
I
think
at
osc
we're
best
positioned
out
of
anybody
else
in
the
world.
As
far
as
doing
low-cost
technology,
that's
industrial
grade
and
that's
where
we
can
leverage
and
we
can
leverage
the
collaborative
development.
I
would
also
like
to
see
the
inclusion.
A
A
That's
a
possible
outcome,
it's
not
impossible!
It's
there's!
So
much
volume
of
waste
that's
generated,
and
specifically
that's
300
million
divided
by
2..
300
million
tons
is
the
annual
plastic
production
people.
That's
a
global
figure.
Half
of
that
ends
up
in
the
waste
stream,
probably
across
the
earth
and
in
the
oceans.
Well,
a
lot
in
landfills.
A
It's
waste!
What
happens
to
it,
some
of
it
may
be
recycled.
I
don't
know
what
percentage
it
is
recycled.
I'm
not
sure.
I
don't
think
it's
a
lot
altogether.
A
A
Now,
one
single
person
is
not
going
to
solve
the
plastic
problem,
this
has
to
be
distributed
and
global
worldwide
and
technology
has
to
be
accessible,
low
cost
enough
that
this
can
spread
widely
widely
that's
the
requirement
we
have
to
optimize
it
to
the
point.
So
so
the
problem
statement
is
simple:
let's
optimize
this
system
and
if
we
look
at
the
actual
components
we
can,
we
can
say
this.
This
is
the
price
of
a
system
that
starts
with
a
bale
of
trash
and
which
produces
your
building
panels.
A
We
could
even
say
something
like
the
challenge
maybe
like,
so
we
have
to
be
very
clear
on
defining
goals.
What
is
the
winning
entry?
Maybe
it's
an
actual
house,
that's
been
produced
by
this
printer.
That's
that's
your!
That's!
A
that's
big!
Imagine
here
we're
developing
this
whole
thing
and
it's
not
just
that
machine
because
you
might
question
well
what
can
it
do?
Well,
how
about
we
make
it
even
the
house
itself.
A
We
want
to
relate
this
to
the
cdca
home.
We
do
plan
on
making
our
own
lumber
trim
and
stuff
going
forward,
but
why
not
leverage
the
entire
world
to
help
us
on
that
yeah
that
that
sounds
good,
and
then
you
have
to
look
at
some
of
the
practicalities.
How
long
would
it
take
to
print
one
of
these
houses?
A
Well,
the
current
rates
using
existing
open
source
extruders,
you
get
20
pounds
per
hour,
20
pounds
per
day
for
24
hours.
So
that's
the
super
volcano
nozzles
and
super
volcano
heater
blocks.
They
are
open
source.
You
can
actually
do
that
and
we
can
increase
that
a
little
bit
we
can
probably
get
to
you
know
to
more
than
that,
but
multiple
print
heads
would
solve
that.
So
you
have
a
printer
that
the
the
solution
would
probably
have
to
be
multiple
print
head
so
that
you've
got
one
machine
with
multiple
heads.
A
Then
that
does
it
so
you're,
not
printing
one
panel.
At
a
time
you
might
be
printing
like
four
or
eight
at
a
time-
maybe
just
plain
replicas-
that's
that's
feasible,
but
four
or
eight.
So,
let's,
let's
say
we
get
to
four
four
would
be.
I
think
rather
easy.
Eight
is
eight,
I
think,
is
quite
doable.
It's
not
major
technical
challenges
for
getting
eight
printheads
on
a
big
printer,
but
let's
say
we
get
to
eight
times
twenty.
You
can
probably
optimize
the
20
to
more
like
40.
A
Possibly
I
don't
there's
no
technical
reason
that
says
you
can't
so
let's
say
we
get
eight
heads
times,
forty
three
hundred
twenty
pounds
per
day.
So
how
long
would
it
take
to
print
the
house?
A
A
That
would
be.
That
would
be
good
that
the
numbers
do
add
up.
So
this
is
not
a
far-fetched
thing.
The
num,
the
amount
of
plastic
that's
out
there
in
the
waste
stream
is,
is
huge
and
also
the
the
productivity
of
a
printer
like
this
could
be
quite
good
and
then
some
of
the
challenges
are
okay.
Let's
make
this
a
multiple
print
head.
Let's
do
the
the
challenges,
the
heated
chamber,
technology.
A
As
far
as
extrusion
technology,
I
mean
that's
pretty
much
a
done
deal
the
way
we
do
things.
We
can
actually
scale
the
the
heater
blocks
in
order
to
to
make
higher
extrusion
happen.
That's
something
we
can
readily
do
here,
so
we
can
actually
have
no
problem
on
the
frame
on
a
motion
system
on
the
extrusion
system.
A
The
challenges
that
the
things
we
have
not
done
are
simply
the
height
high
temperature
chamber,
but
I
don't
see
technical
issues
on
that
there's
a
design
and
I'll.
I
will
get
into
that
because
I
think
that's
one
of
the
most
core
components
that
plus
a
low-cost
shredder.
So
how
do
you
get
to
a
low-cost
shredder?
You
need
some
blades
to
do
it.
A
You
could
do
it
the
cheapest
motor
out
there
you
can
do
that
with
is
actually
a
treadmill
motor
that
costs
50
bucks
and
it's
quite
replicable
for
three
horsepower
or
five
horsepower
at
fifty
dollars.
You
can't
do
better
than
that
for
any
kind
of
motor.
That's
just
one
thing
for
the
shredder
blades
I
mean
possibly
include
the
torch
table
as
a
way
to
get
there
a
simple
torch
table
that
could
perhaps
be
a
bootstrap
machine.
You've
got
this
printer
that
you're
making
but
say
you
want
to
replicate
this
machine
at
scale.
A
If
you
have
one
of
maybe,
if
you
have
a
torch
table,
you
can
do
it
very
inexpensively.
But
what?
If?
What?
If
perhaps
I
mean
one
one
consideration
could
be?
Can
we
actually
include
the
torch
table
as
part
of
the
infrastructure?
That's
required
here,
because
that's
what's
going
to
get
you
the
whole
system
at
rock
bottom
price
like
say
the
shredder,
blades
or
other
components
for
the
system,
so
you
can
think
think
like
that
or
think
about
here's
a
part
of
this
challenge.
That's
how
do
you
make
this
large
machine
at
ridiculously
low
cost?
A
A
You
know
that's
100,
that's
not
too
much,
but
but
you
can
also
think
about
okay,
here's
the
how
about
if
some
of
the
components
of
the
entire
system
are
also
from
waste
plastic,
so
so
that
the
system
would
be
a
bootstrapping
system
where
you
can
do
a
smaller
printer
just
to
get
you
some
of
the
parts
from
trash,
so
you're,
starting
with
bootstrapping
this
this
plastic
recycling,
to
build
to
get
to
the
actual
thing.
So
technically,
you
can
think
about
a
lot
of
creative
ways
to
to
solve
this
problem.
A
If
you
want
to
do
something
at
a
very
low
cost,
but
it's
a
very
interesting
problem
because
I
mean
if
the
fruit
is
clean
up
plastic
waste
and
then
maybe
by
the
the
kind
of
collaborative
protocols
that
we
develop
here,
we
can
make
this
a
pattern
for
more
people,
and
then
the
thinking
here
is
this
kind
of
thinking
gets
us
to.
A
I
mean
really
like
this
is
like
about
transcending
artificial
scarcity
here
that,
like
pretty
high
up
the
goals
of
osce,
if
we
create
a
new
pattern
for
doing
this,
like
actually
show
that
collaborative
development
can
do
something
like
this.
So
I
think
on
many
fronts.
This
is
this
is
quite
interesting
and
and
could
produce
cultural
change
and
tangible
results
at
the
same
time.
A
A
I
want
to
see
this
happen
and
open
it
up
to
the
whole
world
and
see
if
a
bold
call
to
for
collaboration
can
get
more
resources
in
terms
of
prize
money
in
terms
of
hero
x,
the
platform
there
there's
a
charge
for
that
platform
too,
so
and
we're
thinking
about
using
it
and
they
charge
like
10
so
like
if
we
have
a
prize,
if
we
collect
say
up
to
a
quarter
million
quarter
million
sounds
good.
That
sounds
like
something
considerable
well
the
charge
for
that
would
be.
A
That's
when
everyone
gets
to
pay
in.
You
know
the
conditional
acceptance
we
say
we're
following
we're
pursuing
this
goal.
Once
we
can
collect
enough
support,
we're
going
to
do
it,
so
we
can.
We
can
frame
it
that
way.
So
it's
a
it
mitigates
risk.
It
says
that
okay,
we
have
enough
resources
to
make
this
go
forward
well
and
incentivize.
A
lot
of
people
and
people
are
more
willing
to
collaborate
and
throughout
this
process,
invariably
we're
going
to
run
into
a
lot
of
interesting
people
collaborators.
This
is
a
huge
publicity
thing
too.
A
I
mean
to
do
something
like
this
will
will
get
you
into
media,
so
I
think
this
it's
quite
exciting,
and
maybe
so
today
what
we
wanted
to
do
on
this
is
actually
so
one
get
into
the
some
of
the
technical
aspects
and
talk
about
all
the
other
resources
that
are
required
to
do
this.
So
I
mean
what
are
some
of
the
resources
there's
going
to
be
a
promo
video
for
this
going
to
be
marketing
copy
here
here?
Here's
what
the
world
hears!
A
Here's
our
posting
actually
on
the
incentive
challenge,
there's
going
to
be
reward
structure!
Okay,
how
do
you
actually
grade
the
entries
from
the
get
go?
I
could
see
things
like,
so
this
is
going
to
be
once
again.
The
cultural
shift
will
be.
Some
of
the
rules
might
be
free,
cad,
uploads,
uploads
downloads,
like
you
get
rewarded
for
how
much
you
upload
and
download
how
much
you
upload
into
the
design
and
how
much
you
actually
build
upon
other
people's
work
by
downloading
and
then
re-uploading.
A
We
can
track
that
through
time,
logs
on
a
wiki
or
through
simple,
commit
logs
on
a
wiki,
so
there's
a
whole
whole.
What
do
you
say
algorithm
for
how
we
would
grade
the
actual
entries,
but
it
has
to
incentivize
the
fact
that
we're
collaborating
and
probably
something
like
a
grand
prize
with
many
small.
A
Secondary
prizes,
because
the
thing
is,
we
probably
wouldn't
be
may
or
may
not
be
wise
to
say:
oh
we're,
gonna
con
divide
the
reward
money
simply
by
how
much
people
contributed.
I
don't
know
we
have
to
think
about
the
psychology
of
that
and
maybe
kind
of
vet
that,
but
typically,
what
happens
in
these
challenges.
Is
you
get
this
grand
prize
and
a
few
smaller
ones?
A
A
That's
the
question
we
want
to
answer.
I
would
propose
we
launched
this
perhaps
and
I'll
open
it
up
to
the
crowd
here,
but
I'm
thinking
so
we
need
a
few
months
to
prepare
this.
We
wanted
to
do
the
saturdays
on
all
these
collaborative
global
collaborative
protocols,
so
so
we're
going
to
continue
this
every
saturday
for
the
next
six
months.
A
We
do
need
some
time
to
prepare,
and
so,
when
we
launch,
we
have
a
a
solid
offer,
some
good
videos,
like
maybe
an
apprenticeship
right
now
we
are
going
to
be
building
the
large
printers
and
the
summer
x
we're
going
to
be
building
the
large
printers
and
shredders
the
high
temperature
chamber.
Yes,
so
we
can
be
feeding
all
that
through
the
process.
A
Saying:
okay,
hey
people,
we've
got
this
already
built
upon
it.
I
think
the
idea
of
admissible
parts
is
a
good
idea
to
focus
people
on
okay.
This
is
what
we
know
works,
so
we
get
people
onboarded
rapidly
for
what
are
the
best
practices,
all
the
knowledge
that
you
know
that
we
know
about
this
problem.
That
means
large,
high
temperature,
printers
shredding
and
recycling
get
all
the
knowledge
in
the
world
collecting
collecting
around
this.
So
I
think,
there's
a
lot
of
possibility.
A
From
here
I
just
want
to
like
technically
why
why
I
feel
pretty
good
about
the
possibility
here
is:
is
the
two
technologies
that
we
do
have
are
the
universal
axes
right
now
and
the
high
temperature
chamber,
which,
as
I
mentioned
the
motion
systems,
do
exist
in
open
source
people
make
various
versions.
I
think
the
universal
axis
is
the
I
mean
humbly
speaking
the
best
there
is,
I
don't
see
anything
else,
that's
as
scalable
in
size
or
simple
to
make
in
terms
of
part
count.
I
mean
I
study
this
thing.
A
That's
and
I,
and
I
would
actually
venture
to
say
that
a
system
like
the
universal
axis
would
be
is
degenerate.
What
do
I
mean
by
that?
Degenerate
means
that
if
you
have
the
requirements
of
highest
performance
and
lowest
cost
and
some
of
the
other
features
modularity
scalability
you're
going
to
get
something
that
looks
like
that.
A
So
I
mean
I
I
can
pretty
much
guarantee
you
that
so
it's
the
general
design,
we're
saying
these
are
some
of
the
best
practices
that
we
reduce
to,
because
we
know
they
work
and
we
can
vet
that
too.
It's
like
part
of
the
challenge
could
be
okay.
Can
you
devise
a
better
universal
access
system,
meaning
a
general
purpose,
xyz
and
rotary
motion
cnc
system?
A
Well,
we
think
we've
got
that
we're
on
our
system,
we're
also
using
ramps,
just
simple
20
board
to
control
the
entire
system.
That's
all
we
can
do
for
the
entire
printer,
just
put
external
stepper
drivers
which
allow
you
to
drive
any
size,
stepper
motors
for
whatever
size
of
3d,
printer
or
device
that
you
need
so
that
the
controller
technology
is
completely
open.
Source
universal
axes
are
completely
open
source.
A
I
also
know
so
monofilament
making
there's
people
working
on
it.
I
mean
I
I
like
to
talk
about
michigan
tech,
lab
people,
so
josh
joshua
appears
there
because
he's
actually
working
on
an
extruder
screws
that
are
diy
open
source.
Actually
they
are
open
source,
cnc
grinder.
That
actually
makes
them
that's
not
out.
Yet
it's
it's
common,
but
you
know
it's
problems
here
are
not
not
super
challenging
they're
they're
good
they're,
just
I
think
at
the
right
right,
complexity,
level
that
lends
itself
to
large
development.
A
I
do
want
to
talk
about
the
the
chamber,
the
the
high
temperature
chamber,
just
so
you
can
get
the
the
understanding
of
what's
involved
and
what
problem
we
have
to
solve
because
that's
yeah.
So
we
would
like
to
today
what
we
want
to
do
is
break
into
different
groups
and
work.
Okay,
here's
the
technical
group
that
will
assess
and
define
here's
what
we
think
like.
Ultimately,
it's
going
to
be,
I
think,
price
point,
because
we
know
the
technology
that
works
here.
A
We
know
how
much
it
costs
what
it
can
do,
that
you
can
define
in
an
engineering
sense,
and
then
we
say,
after
a
very
careful
analysis
of
that
in
a
technical
group.
Here
we
can
say
this
is
what
we
expect
as
the
price
point,
based
simply
on
the
amount
of
materials
we're
using
the
technologies.
We're
using.
You
can
be
very
rigorous
in
defining
that
and
I
think
that's
the
value
we
can
produce
here.
A
A
I
think
there's
business
development
on
this,
where
okay,
here's
the
actual
model
of
how
much
you're
producing
what
the
costs
are,
etc.
There's
posting
the
incentive
challenges.
Video
like
let's
come
up
with
a
video
script,
so
various
assets
that
are
required
so
I'll,
maybe
continue
for
about
20
more
minutes
on
what
all
we
could
do
and
then
I'd
like
to
break
down
into
groups
and
start
a
working
dock.
A
So
for
now
I
want
to
get
into
the
actual
high
temperature
chamber
technology,
and
I
want
to
explain
that
really
briefly,
so
that
you
appreciate
something
that
doesn't
exist
because
nobody's
done
it.
I
mean
the
problem
statement.
Is
this:
it's
in
a
high
temperature
chamber.
You've
got
a
nozzle
with
a
with
a
stepper
motor.
Typically,
you've
got
this
thing
where.
A
The
problem
with
that
is
that,
at
that
kind
of
temperature,
you're
melting,
your
electronics
and
other
structures,
if
they're,
if
they're,
not
steel,
so
you're
melting
things
like
the
the
windings
within
the
stepper
motors,
the
stepper
motors
are
rated
only
for
60c
typically,
so
you
cannot
put
any
of
your
sensitive
elements
within
the
hot
temperature
area,
so
the
problem
statement
is
rather
simple:
keep
everything
out
of
the
heat,
except
for
the
tip
of
the
nozzle.
That's
what
it
boils
down
to
other
people.
A
Try
to
do
clever
things
like
oh
yeah,
throw
that
in
there
and
maybe
cool
parts
of
it,
water,
great
sure,
that's
complicated!
Just
keep
everything!
That's
sensitive
out
of
that
chamber
start
with
that
idea
and
solve
for
that,
because
that's
a
robust
design
can't
beat
it
simplest
solution
to
this
problem
of
frying
things
in
a
hot,
basically
think
about
an
oven.
You
got
to
keep
your
sensitive
things
out
of
the
oven,
so
we
know
right
now
we
can.
A
We
can
do
this.
I
think
there's
a
good
way
to
do
this,
so
I'll
describe
what
we
can
do
so
ideas,
you've
got
your
high
temperature
chamber,
it's
insulated
and
you
have
a
shield
on
top
very
simply,
the
head
moves
with
the
shield
and
it's
enclosed
at
the
top.
So
I
have
a
diagram
of
this,
so
I
want
to
show
this.
So
it's
let
me
share
my
screen.
A
You
have
a
hot,
the
red
stuff
is
the
hot
chamber
you
have
so
the
universal
axis.
On
top
y-axis
z-axis
there's
a
build
plate,
the
z-axis
has
to
go
up
and
down.
So
the
problem
is,
if
you're
moving
in
three-dimensional
motion.
How
do
you
get
all
those
motion
systems
out
of
that
hot
area?
Well,
in
this
diagram,
you
see
that
definitely
the
x
and
y,
which
are
on
top
the
the
carriage
this
should
say
carriage
x.
A
That's
the
x-axis
call
that
where
the
extruder
rides
on
the
x-axis
back
and
forth,
you
get
the
y-axis
which
mean
goes
in
and
out
of
the
page,
so
you've
got
2d
right.
There.
There's
two-dimensional
motion
x
y
that
if
you
sep
that
would
be
easy
to
to
do
like
two
dimensional
drawings,
where
you
know
you're
just
drawing
on
a
on
a
high
temperature
surface.
A
But
here
you
gotta
go
up
in
z.
So
the
way
we
we
do
that
here.
What
we
do
is
we're.
Attaching
this
see
this
red
thing
here.
That's
a
guard!
A
A
A
So
what
I
see
here
is
you
have
a
one
or
two
like
if
it's
the
universal
axis,
which
we
typically
support
on
two
rods,
just
cut
two
slots
or
even
like
make
it
one
rod
and
make
that
make
a
vertical
slit
in
that
hot
temperature
chamber
put
some
wipers
around
that
soft
material,
like
maybe
carbon
fiber
blanket
or
something
like
fiberglass
that
wipes
against
that
the
rods
that
are
sticking
into
the
chamber
so
that
you
get
temperature
enclosure.
You
can
definitely
heat
the
chamber.
A
You
can
put
heaters
inside
there,
so
the
limit
to
this
system
here
is
depend
depends
on
what
the
material
for
that
wiper
at
the
top
is.
I
was
thinking
for
a
lightweight
transparent
one.
You
can
actually
use
pei,
which
is
what
we
use
on
the
print
bed
surface
right
now,
that
material
is
good
for
up
to
167
c
continuous,
so
right
there.
If
we
do
that,
we
have
the
technology
to
create
a
high
temperature
chamber
for
167c,
and
I
think
that's
that's
more.
A
I
think
that's
enough,
I
don't
think
we
need
to
go
higher
than
that.
What
you
need
to
do
is
for
proper
print
bed.
Adhesion
is,
you
have
to
be
below
the
melting
temperature
of
the
plastic.
A
I
think
167
for
ambient
temperature
can
probably
get
us
there
and
if
you
stand
up
some
thermal
gradients,
such
as
the
heater
being
at
the
the
bottom
convection
makes
heat
go
up,
so
it's
a
little
cooler
at
the
top,
so
you
can
have
the
print
area
pretty
hot.
Now,
because
the
the
the
guard,
the
red
guard
there,
the
red
closure,
is
against
ambient
temperature.
On
the
other
side,
it's
you
know,
one
one
side
might
be
quite
hot.
The
other
side
will
be
cooler,
so
this
could
probably
not
only
get
you
like
167.
A
It
might
get
you
10
or
20
degrees
even
higher,
because
it's
getting
cooled
from
the
top
just
by
ambient
temperature
so
and
the
thickness
of
that
is
like
0.1
of
an
or
0.05
or
so
of
an
inch
it's
standard.
This
is
already
stuff
we're
using
already
so
I
have
experience
with
this.
We
we
have
a
lot
of
experience
with
this,
so
you
can
cut
out
a
sheet
like
that
now.
A
A
So
I
don't
see
this
costing
150
000
or
more
like
a
comparable
printer.
This
could
cost
us
about
5k
or
so
for
a
large
for
a
large
one
for
a
small
one.
You
know
maybe
500
above
our
ticket
price
right
now.
It's
so
you're
talking
about
an
insulated
heated
chamber,
probably
take
take
plates
of
steel.
Put
some
insulation
in
that
build
it
around
weld
it
around
or
do
some
other
comparable
mechanism.
A
So
does
anyone
have
any
questions
on
this
just
technically
speaking,
because
I
think
this
is
kind
of
like
this
right
here
does
not
exist
in
the
open
source
and
you're
going
to
pay
tens
of
thousands
of
dollars
for
this
right
here.
A
A
Here
you
can
just
by
again
temperature
the
build
plate
hot
enough,
it'll
stick
and
you
can
still
use
pei
as
the
as
the
basic
substrate
get
it
high
enough.
It
will
stick.
You
have
to
control
the
temperature,
that's
fine.
We've
got
temperature
controls
open
source,
that's
marlin
and
ramps.
That's
fine,
not
a
problem,
so
there
we
go
any
questions
on
this.
Does
this
make
sense
or
or
like?
A
Is
there
like
a
type
one
error
on
this
that
this
somehow
is
flawed
in
concept,
because
we
start
this
with
this
concept
and
then
we
go
about
implementing
it?
I
mean
this
is
obvious
and
simple
in
my
view
yet
nobody's
like
the
people.
I've
seen
do
this.
A
The
common
thing
is
they've
got
these
bellow
shaped
things
that
fold
on
top
like
a
bellows
that
that
would
fold.
On
top
great,
I
mean
why
the
complexity,
that's
there's,
patents
on
that
they,
I
think,
expired
already,
but
that's
too
complicated
just
do
a
simple
sheet.
Just
make
it
right
on
top.
What's
the
big
deal
here,
I
don't
know,
I
don't
see
any
problem
with
that.
C
A
A
C
Yeah
yeah
so,
and
this
is
on,
but
so
so
what
you're
describing
that
seems
pretty
straightforward
to
you,
then
the
the
question
that
I'm
I'm
unclear
on
kind
of.
What
would
people
be
trying
to
figure
out
for
this
competition
like
like
just
building
this
like
according
to
what
you've
described
or
are
there?
Are
there
still
tons
of
questions
about
implementation.
A
Yeah,
I
see
what
you're
asking
and
I
think
the
answer
is
one
communicated
effectively.
That's
all
that's
called
graphics
and
media
and
pr
get
enough
people
to
show
up
make
a
compelling
case
for
this.
But
second,
we
have
not
built
this.
Yet
we
will
in
the
summer,
but
I
mentioned
the
other
day,
that
you
need
a
hundred
or
a
thousand
iterations
before
it
works
to
the
best
product
in
the
world.
That's
where
we
need
the
collaboration.
A
A
A
Yes,
so
so
there's
two
phases:
one
is
actually
posting
this
challenge.
So
posting
this
challenge
is
effectively
a
communications
question.
This
is:
writing
and
media
video
so
forth.
We
can
do
some
of
that
here
and
maybe
we
can
get
collaborators
remotely
that
can
help
us
on
that,
so
we
can
actually
feed
assets
like
okay.
So
in
a
promo
video
of
this
you
see.
Okay
and
now
you
can
use
this
universal
axis.
You
can
make
this
big
thing.
We've
already
done,
maybe
like
we
just
prototyped
the
small
heater
chamber,
now
we're
gonna
size
it
up.
A
A
A
I
think
a
lot
of
that
would
be.
Of
course
here's
the
development
of
the
actual
machines,
but
let's
make
it
even
bigger-
let's,
let's
let's
say
we're,
actually
developing
a
commercially
viable
way
to
produce
this,
so
there's
business
development.
Let's
make
this
into
a
product.
The
idea
here
is
extreme
enterprise.
A
This
is
we're
collaboratively
developing
the
product,
but
product
is
different
than
enterprise
product
is
or
even
project
like
this
project,
product
and
enterprise.
A
project
is
not
a
product.
A
If
you've
got
a
product,
you
don't
necessarily
have
prototy,
have
an
enterprise
like
a
refined
enterprise
like
right
now
we
can
sell
the
3d
printers
it's
somewhat
enterprise
level,
but
to
take
it
to
okay.
Now
we're
like
actually
making
a
lot
of
money
and
many
people
are
doing
the
same
around
the
world.
That's
what
I
mean
that's
when
the
enterprise
has
been
developed,
so
we're
gonna
try
to
push
the
world
towards
that.
A
Saying
that
okay,
here's
not
only
the
the
device,
but
here's
the
dissemination
of
it,
so
training
materials,
perhaps
training
problems,
and
the
question
is
how
much
of
that
do
we
throw
under
the
bus
here
in
terms
of
putting
that
into
the
challenge?
We
have
to
say
okay,
this
is
what
we
want
in
a
challenge
and
make
it
realistic
so
that
it's
actually
doable
right.
So
maybe
we
decide
oh
well,
maybe
just
leave
it
at
the
technology.
A
A
That
would
be
like
the
minimum,
but
I'd
like
to
see
an
enterprise
around
it,
a
distributive
enterprise,
meaning
we're
actually
producing
assets
of
education,
so
that
all
the
people
here
go
to
to
their
parts
of
the
world
and
start
this
enterprise
or
every
or
many
other
people
do
that
or
we
we
train
more
people
like
next
year.
We
we're
starting
to
train
people
to
actually
build
these
franchises
out
like
boxable,
so
actually
right.
So
you
guys
heard
about
it
so
right
box.
Look,
you
know,
boxable.
A
That's
a
franchise
for
for
this
house.
That's
actually
competitive
with
us,
it's
very
close
to
us
in
price.
Actually
so
they're
gonna
cost
about
200k.
I
looked
at
their
numbers
and
they
have
a
small
micro
house
that
they're
creating
a
worldwide
franchise
about
that
cost.
Fifty
thousand
dollars
for
375
square
feet,
but
that
doesn't
include
foundation,
installation
transportation
of
that
thing
to
your
place.
So
I
think,
at
the
end
of
the
day
I
kind
of
went
through
the
numbers.
It's
gonna
be
a
minimum
of
170
to
200
000.
A
So
it's
around
our
price
point
we're
saying
100k
for
us
without
the
land,
so
they're
close,
I
like
it
because
they're
just
becoming
efficient.
They
basically
say
that
they're,
like
wes
talking
about
that
boxable
they're
they're
efficient.
I
looked
at
their
stuff,
they're
they're,
saying
yeah.
We
just
you
know
they're
just
optimizing.
A
You
know
because
housing
is
super
inefficient.
That's
it's!
That's
the
that's!
The
real
advantage
there
house
house
building
today
is
very
inefficient
and
very
wasteful
in
terms
of
material
use
and
various
things
that
basically
stemming
from
the
the
fact
that
the
designers,
not
the
engineers,
not
the
designer
designers,
not
the
builder,
the
builders,
not
the
user.
The
user
is
not
the
service
person
stuff,
like
that.
A
lot
of
that
break
and
the
way
that
things
work
and
financing
and
all
that
adds
up
to
a
high
cost
of
housing.
A
So
the
concept
for
the
heated
build
chamber
is
it's
there
for
the
regarding
the
actual
technology
of
grinding
is,
I
think,
there's
a
lot
of
creativity.
We
can
put
our
heads
around
with
that.
I
think
there's
there's
a
lot
of
work.
The
way
you
can
reduce
that
price
is
being
very
effective
about
it
and
you
can
do
things
like
3d
printed
belts.
If
you
want
super
low
cost
gear
down,
tpu
does
exist.
It's
an
amazing
material,
thermoplastic
urethane,
which
which
is
rubber.
A
We've
printed
some
prototype
belts.
Here
you
can
think
about.
How
do
you
make
that
device
super
low
cost?
Imagine
like
what
I
see
here
is.
If
you
have
access
to
low
cost
plastic
through
a
bootstrap
plastic
operation,
then
you
can
get
the
entire
infrastructure
for
this
life-size
system
that
produces
house
panels
at
very
minimal
cost
like
for
the
shredder.
A
You
can
get
it
to
near
free
minus
the
motor
is
going
to
cost
you
fifty
dollars
for
three
horsepower,
but
that's
enough
for
industrial
grade,
for,
like
probably
like
a
thousand
or
so
pounds
of
grind
per
day.
At
least
you
can
do
3d
printed
bearings,
so
any
electromechanical
devices,
a
motor,
shaft,
couplers,
bearings
bearings.
We
have
prototype
here,
you
can
take
commercial
balls
which
cost
only
a
few
cents
and
you
can
create
the
3d
structure
for
a
high
high
force
bearing
otherwise
a
bearing
like
that
is
75
dollars
each.
A
So
this
is
like
where
the
costs
are
hanging.
You
start
looking
at
here's
each
element:
let's
3d
print,
that
from
waste
plastic
and
add
a
little
bit
of
metal
to
it
and
you've
got
a
high
powered
device
at
low
cost.
So
the
bearings
we
can
nail
the
belts
we
can
nail,
the
motor
is
50
and
for
the
actual
rotor,
how
about
metal
tip
inserts
so
that
into
a
large
plastic
rotor
structure.
A
Like
that's
one
way
I
can
see
because
the
blades
are
going
to
cost
a
bit.
You
know
if
you
go
in
industrial
grade,
you've
got
a
cnc
cut
them.
What?
If
it's
just
we're
we're
doing
the
tips
like
insertable
tooth
blades,
like
on
some
sawmills
and
things
like
that
insertable
teeth,
replaceable
teeth,
adjust
the
tooth
is
the
high
performance,
metal,
abrasion
resistant
metal?
The
rest
is
plastic,
you
know,
so
you
can
talk
about
a
lot
of
different
tricks
to
to
make
this
low
cost.
A
E
Is
that
the
goal
is
to
be
able
to
melt
existing
plastic
like
credit
and
melt
it
and
then
yeah
turn
it
into
filament?
Is
the
heated
enclosure
only
needed
for
this,
and
not
at
all.
A
It's
needed
for
everything
for
the
point
about
the
heated
enclosure
is
that
you
can
only
print
with
some
select
low
temperature,
lower
temperature
plastics.
You
cannot
print
with
any
high
temperature
plastics,
because
when
it's
at
ambient
temperature
or
not
high
enough
like
the
higher
the
temperature,
the
higher
you
need
the
enclosure,
otherwise
the
the
layers
don't
stick.
E
Oh
so
it's
durability
like
higher
temperature
of
plastics
like
right
now,
this
3d
printer
doesn't
fit
with.
A
It's
not
a
high
performance
printer,
it's
a
it's
just
your
it's,
not
hobby,
because
we
produce
large
parts
on
it,
but
it's
not
industrial
grade
or
high
performance
in
the
sense
of
printing
with
high
temperature
plastics
like,
for
example,
there's
pei,
which
is
actually
the
bed
surface
which
we
use
on
the
the
heated
bed.
You
can
actually
print
with
that.
That's
a
thermoplastic,
but
not
in
this
printer,
so
you
can
actually
do
things
like
with
that
high
temperature
printer.
A
So
things
like
that,
but
yeah
you,
you
need
it
for
anything
like
right
now.
That's
why
that's
the
point
I'm
trying
to
make
right
now,
3d,
printing,
in
an
open
source,
is
in
a
stone
age.
We
came
out.
We
we
had
the
major
breakthrough
about
2011
or
12
when,
when
the
reprap
project
came
out
and
the
first
3d
printers
became
a
reality
that
were
open
source,
so
you
didn't
have
to
pay
10
000
for
a
printer.
You
can
build
one
for
like
500
bucks.
A
We
got
to
take
this
to
the
next
step
and
that
is
the
high
temperature
chamber
and
large
size
printers
that
work
so
you're
opening
up
to
like
and
the
other
thing
is
plastics
are
not
necessarily
like
super
high
temperatures
like
polyethylene.
It
will
not
stick
to
itself
in
in
ambient
temperature.
You
cannot
print
with.
It
won't
stick
to
your
bed.
It
won't
stick
to
yourself
to
itself
the
way
that
the
3d
printers
work
when
you
extrude
the
plastic,
it
actually
melts
the
layer
below
it.
That's
how
it
works.
A
A
A
We
can
be
processing
everything
every
single
part
here,
this
your
old
cell
phone,
that
you
shred
and
get
the
plastic
out
and
separate
the
metal
and
all
the
bottles
everything
so
you've
got
now.
You've
killed
off
the
waste
plastic
issue,
which
is
like
half
a
trash,
the
organics,
you
can
all
compost
any
metals
you
shred
and
reuse
and
re-melt
with
that's
our
next
problem
statement
in
a
year
or
two
with
induction
furnace
right
now
we're
at
the
level
of
let's
solve
plastic.
F
A
The
second
part
of
that
is
there's
both
there's
certain
plastics
that
completely
are
miscible
and
blendable.
Others
are
not
so
part
of
this
would
be
developing
formulas.
So
certainly,
if
you
have
a
single
single
trash
bill,
they
typically
separate
them
for
you
already
or
you
can
separate
it
yourself
if
you're
collecting
it
yourself.
A
But
now,
if
you
start
mixing,
you
just
got
to
pay
attention.
You
have
to
know
which
ones
you've
mixed
so
that
you
know
they're
going
to
stick
together
or
you
can
say:
oh
I've,
just
just
got
a
little
bit
of
this
other
plastic
like
a
little
ball
of
it
in
this.
In
this
big
bell,
it
won't
matter
right
so
there's
strategies
of
how
you
do
that
and
then
with
when
you're
printing
with
large
nozzles.
It
doesn't
matter
that
the
plastic
is
is
dirty
because
all
the
dirt
will
go
right
through
the
nozzle.
A
It
is
the
more
heat
it
has,
so
it
can
melt
the
layer
below
it
better
and
it
it's
much
stronger
prints.
So
actually
our
prints,
even
though
they're
pretty
ugly
they're,
actually
much
stronger
than
typical
prints
yeah.
So
there's
a
whole
thing
about
material
science
and
developing
blends
like
what
blends
well
with
each
other.
A
That's
a
whole
productization
part:
okay,
here's
how
here's
a
process
for
taking
for
going
to
your
cafeteria
and
making
cafeteria
tables
from
your
trash
or
whatever
you
know.
A
You
can
try
it,
but
the
limits.
A
A
A
Yeah,
if
it's
easier,
but
I
I
if
we
can
show
that
that's
easier
than
two
stepper
motors
and
metal
rods,
penetrating
the
chamber
in
the
metal
rods
penetrating
the
chamber-
it's
not
technically
complex.
You
can
have
wipers
around
the
rods.
Recently
I
ran
into
we
use
carbon
fiber
blanket.
That's
a
really
nice
material.
That's
like
2
000
celsius.
Melting
point
like
really
high.
That's
like
welding
blanket
carbon
fiber,
that's
a
great
wiper
for
example!
A
So
I
don't
think
that
that's
too
difficult
to
do.
You
could
do
a
single
rod
like
a
say,
a
one
inch
or
even
or
like
a
more
of
a
vertical
rod
on
a
z-axis,
so
it
cuts
through
that
slit.
It's
only.
I
would
do
that.
It's
a
single
rod,
you're
going
up
through
a
slit
in
a
high
temperature
chamber,
so
you've
got
two
penetrate
two
linear
slits
in
a
high
temperature
chamber
that
go
up
the
side,
not
not
difficult.
I
don't
see
that
we
can
do
better
price
wise.
We
can
consider
it.
A
We
can
definitely
evaluate
okay,
here's
the
actual
cost,
because,
with
that
you're
gonna
have
to
have
a
compressor
or
hydraulic
system
which
would
add
a
bit
of
cost
unless,
unless
we
say
oh,
this
is
a
system,
you
can
run
off
a
tractor
for
example,
or
something
like
that.
We
want
to
make
it
as
accessible
as
possible
so
that
meets
our
criteria
of
transparent,
collaborative
open,
scalable
replicable.
We
can
definitely
look
at
it
and
that
could
be
a
technical
point.
That
would
definitely
actually
be
good.
As
a
point:
hey
we've
evaluated
the
hydraulic
system.
A
This
is
the
lowest
cost
and
performance
we
could
get
out
of
that.
It's
primarily
going
to
boil
down
to
cost
and
complexity
of
the
system,
so
you're
adding
another
system.
We
already
have
stepper
motors
like
when
you
add
another
system,
that's
more
complexity,
but
what?
If?
What?
If
we
end
up
doing
the
shredder
on
hydraulics
or
something
I
don't
know,
but
I
see
the
electrical
systems
at
this
scale
like
with
the
actually
the
treader
mill
motors.
A
B
Yeah
yeah.
A
So
I
mentioned
the
carbon
fiber
blanket,
which
is
over
1
000
celsius,
that's
or
fiber
carbon,
not
carbon
fiber,
but
glass,
fibers,
so
fiberglass,
yeah,
they're
soft
materials
that
are
high
temperature
for
wipers
like
that
and
then
see
in
the
high
temperature
the
design
there.
What
I
do
about
that,
I
didn't
do
much
there,
but
there's
also
some,
let's
think
about.
What's
the
chamber
like,
do
you
do
like
fire,
brick?
A
No,
I
said
just
let's
do
just
metal
and
put
some
fiberglass
or
or
more
like
rock
wool
in
it,
which
is
higher
temperature
than
well.
This
is
not
high
enough
for
for
just
plain
fiberglass,
just
plain,
cheap
fiberglass
that
we
use
in
our
house
insulation.
That
would
be
perfect
for
the
actual
insulation
on
a
high
temperature
chamber.
A
That's
only
up
to
like
say
200c,
so
you
only
need
like
the
restriction
here
is
200c,
but
the
thing
is
that
your
electronics
don't
go
more
than
like
60
or
so
like
a
stepper
motor
at
60,
that's
kind
of
the
limit
and,
as
I
said,
you
can
cool
them,
but
that's
a
whole
other
complexity.
Just
keep
it
out.
Simplest.
Just
think
about
the
simplest
solution
from
the
start,
and
I
don't
see
any
technical
reasons
why
this
this
the
simplest
would
not
work.
A
E
E
A
E
B
A
E
A
Yeah,
that's
that's
a
good
point
because
you,
as
paul
pointed
out,
if
you're
closing
the
chamber
with
the
simplest
simplest
mechanism
which
is
just
a
piece
a
sheet
attached
to
the
carriage
on
the
x-axis,
then
in
order
to
cover
the
entire
chamber
in
all
places
that
that
closure
has
to
be
twice
the
size
of
the
chamber.
So
yes-
and
that
means
your
frame-
is
going
to
be
correspondingly
larger.
So
this
is
now
getting
into
the
details,
but
this
is
this
is
structure
and
we're
scalable
on
structure.
So
that's
not
a
big
issue.
A
A
A
If
not,
let's
continue
so
we
have
one
person
david,
who
actually
seated
like
the
the
templates
that
we
we
were
talking
about.
So
let's
actually
get
into
templates
documents
that
we
start
editing
and
dividing
up
roles.
So
on
recent
wiki
changes,
there's
go
down
to
120
design,
lessons
day
three,
so
they
actually
david.
Just
put
this
thing
up:
it's
not
seated
with
documents
yet
because
we
don't
really
have
assets
for
day
three,
but
let's
put
a
document
in
there.
A
That
would
be
I'll
start
a
dock.
Let's
start
a
dock
and
put
it
in
there,
which
we
typically
work
off,
just
a
simple
template.
So
let's,
let's
share
a
doc,
and
now
let's
try
this.
Let's
try
once
again,
we
want
to
get
to
the
point
where
all
of
us
are
collaboratively:
editing
a
single
doc
have
a
mouse,
make
it
easy
for
yourself,
let's
all
edit
a
doc
and
and
contribute
to
it.
So,
let's
try
to.
A
I
want
to
practice
this
like
as
much
as
we
can,
because
the
power
of
this
is
getting
massive
massive
results
collaboratively
real
time,
like
all
the
information
being
caught
and
developed.
At
the
same
time,
if
people
know
how
to
work
this
process,
so
the
why
is
is
significant.
We
can
get
to
transcendent
levels
of
collaborative
development
if
we
know
this
very
basic
capacity,
which
is
many
many
people
collaborating
on
on
a
dock.
A
But
you
have
to
know
something
about
how
you
break
it
down.
So
people
don't
step
on
each
other's
toes
and
all
that,
especially
if
cat
is
involved.
So
there
is
some
knowledge
required
to
do
that,
but
let's
practice
it
at
the
simplest
level
here,
which
is
just
collaborative
edit
of
a
doc.
So,
let's,
let's
make
a
make
a
copy.
A
A
E
E
A
Box
the
chat
box-
I
just
pasted
this
thing-
the
working
dock,
which
I'm
gonna
embed
right
now
into
the
page,
which
is
called
120
design
lessons.
Let's
see
I'll,
send
the
link
for
that.
B
A
A
A
A
A
A
Already
take
a
look
at
that
link,
so
what
are
the
assets
we're
going
to
generate
and
we
want
to
say
here's
the
assets
and
here's
who's
gonna
work
on
today.
So
today
is
a
real
working
session.
We're
actually
doing
this.
We're
collaborating
we're
gonna
start
working
on
here's
the
things
that
are
required,
let's
put
a
little
bit
of
time
and
go
at
it
until
five
spend
all
day
on
it.
A
We
need
a
video
okay
people
type
in
type.
In
some
of
the
things
we
talked
about,
promo
video.
A
A
Now
this
video
is
something
we
can
work
on
so
collect
our
assets
throughout
the
program,
get
the
cameras
out
there
and
when
we're
building
some
of
the
larger
printers
like
this
is
gonna,
be
in
the
next
month.
When
we
build
a
printer
and
build
a
torch
table
and
shredders
and
things
we'll
get
that
capture
that
and
edit
it
that's
gonna,
be
our
assets.
F
B
B
A
A
G
Anything
to
do
with
marketing,
I
could
I
mean
I
feel
like
I
can
communicate
things
give
me
time
to
write.
A
Okay,
do
you
want
to
spend
the
time
writing
some?
We
will
call
this
right
copywriting
or
like
what
technical
writing
copier.
So
what
do
you
need
to
do
that.
G
I
mean
just
to
be
clear
on
the
goals
I
feel
like.
I
can
already
get
started
on
a
lot
of
it.
B
A
So
this
is
we're
getting
into
role,
division
here
already
on
page
two.
So
doom
does
so
you
want
to
do
scripts,
so
scope
it
out
like
so
what
what's
your
goal?
Maybe
yeah
yeah.
So
you
have
some
ideas
for
so
you're.
Thinking
of,
maybe
you
could
start
working
on
a
script
already,
so
the
video
script
like
yeah?
How
many
minutes?
Two
minutes,
I
would
say,
there's
probably
a
couple
of
videos.
A
Ken,
what
do
you
think
you
can
do
to
so?
We
can
succeed
in
this
amazing
challenge
which
we're
gonna
launch
probably
december.
First,
if
it's
six
months,
it's
five
months,
maybe
we
should
should
we
say,
like
five
or
six
months,
maybe
january
1st,
we
launch
it
for
christmas,
launch
it
at
christmas,
christmas
gift
to
the
world.
Well,
I
think.
E
Busy,
well,
I
would.
I
would
say
that
you
should
we
should
watch
it
while
we're
all
here,
because
there's
going
to
be
a
lot
of
ongoing
support,
I
think
that
we're
going
to
discover
anytime,
you
launch
a
contest.
You
know
people
are
going
to
ask
questions,
that's
going
to
be
changes
that
you
need,
you
might
need
to
make
into
the
criteria
or
the
rules,
and
so
it's
going
to
require
that
condolences.
Of
course
you
push
it
out
to
the
world.
A
No,
you
gotta,
we
gotta
talk
about
support
roles
too.
That's
one
of
the
requirements
or
someone's
got
to
manage
it
and
respond
to
it.
How
about
we
do
it
like
december
1,
then,
which
still
leaves
us
because
we're
officially
this
program
ends
december
22nd
before
people
go
home
like
20
seconds,
or
what
do
you
think?
A
Yes,
saturday's
is
dedicated
time
where
we
talk
about
global
collaboration.
This
is
certainly
global
collaboration.
So
let's
focus
on
this
all
the
saturdays,
so
we've
got
six
months
of
saturdays,
which
is
like
24
sessions
or
so
so
we
just
move
forward,
but
yeah
absolutely
like
work
on
it
any
time
off
hours.
If
you
get
time
to
do
it,
yeah.
E
A
So
three
months
takes
us
to
like
october,
but
that's
like
the
middle
of
summer
x,
where
it's
going
to
get
a
little
more
intense,
because
it's
like
back
to
back
oh
yeah,
so
at
that
time
we
can
either
separate
from
the
rest
of
the
activity
and
work
on
this,
but
you're
going
to
want
to
see
most
of
the
probably
most
of
the
activity
that's
happening,
and
a
lot
of
that
will
be
around
housing
right.
A
So
I'm
just
saying,
like
the
amount
of
time
we
have
these,
this
time
is
going
to
just
fly
by
so
I
just
want
to
make
sure
we
have
enough
time
to
do
it
unless
we
get
the
resources
where
somebody
can
sit
in
the
corner
and
like
work
on
this
full-time,
you
know
because
it's
going
to
be
a
bit,
you
know
all
this
work
is
going
to
take
a
bit
of
time.
It
takes
people
launched
like
for
launching
on
the
hero
x
project.
A
A
E
That
I
was
sort
of
like
asked
to
participate
or
contribute
to
this
challenge
like
to
be
part
of
the
launch
team.
So
that's
like.
A
So,
let's
yeah,
so
let's
maybe
leave
that
as
an
open
question
we
can.
We
can
refine
that
do
people
have
comments
elsewhere,.
F
Yeah,
it
seems
like
one
of
the
hard
things
about
managing
collaboration
with
this
project.
Is
that
it's
really
expensive
to
prototype
the
hardware
you
said.
B
B
A
One
thought
about
that
would
be
like
anyone,
who's,
actually
building
stuff
and
actually,
if
they're,
one
of
the
people
they're
building
they're
likely
to
get
far
in
terms
of
their
score
and
that's
where,
if
we
have
a
bunch
of
rewards
for
like
say
it's
a
hunt
say
we
have
a
hunt
250k.
Let's
look
at
some
numbers
250k,
we
got
a
reward,
maybe
do
a
grand
prize
of
100
g's
and
then
150
g's
5
000,
each.
A
That
makes
for
like
what
20
30
30
times.
Five
that
makes
for
30
rewards.
So
30
people
have
gone
all
that
way.
But
now
there's
the
idea
of
partial
prototyping
there's
little
things
you
can
build,
like.
Maybe
pro
develop
this
bearing
this
3d
printed,
bearing
that's
going
to
cost
you
20
bucks
in
off-the-shelf
printer
filament
stuff,
like
that,
I
could
see
like
ideally
a
person
picks.
Okay,
here's
we
do
the
cad,
that's
that's
free
outside
of
your
time
and
then
people
can
prototype
individual
aspects
of
it.
A
F
Need
to
work
with
like
recycling
companies.
A
If
they're
selling
garbage
bales,
then
they'd
be
willing
to
support,
it
could
be
a
thing
to
do
so.
That
could
be.
That
would
be
more
like
that's
that'll,
be
in
the
sponsorship
thing.
So
yeah
record
all
these
things
type
them
in
so
under
what
why
doesn't?
Let's?
Let's
have
each
person
do
a
do
a
page,
but
ken
we're.
A
The
technical
team,
the
assessment
of
the
technology
and
and
preparing
that
okay
start
a
page
on
that.
So
let's
do
let
me
do
I'm
gonna
slide
duplicate,
so
it's
got
our
branding
at
the
bottom.
A
F
A
So
keep
thinking
but
keep
keep
refining
you
on
page
three
for
can
so
wesley
outreach
to
recycling
centers
yeah
keep
going
wes.
F
One
thing
is,
you
know,
I
think
we
like
we
need
to
start
with,
like
maybe
refining,
like
our
existing
d3d
printer.
B
F
F
Building
like
a
decentralized
hardware,
collaboration
protocol
or
like
an
editor
for
some
of
this
stuff.
F
Like
I,
ideally,
I
think
we've
got
to
like
combine
like
all
all
of
this
data
into
a
single
like
like
like
real
time,
multiplayer
systems,
so
you
know
like
we
need
to
have
the
slide
like.
Basically
it's
like
google
slides
technology.
You
know.
F
In
a
graph
to
a
cad
model,.
B
F
And
so
jindal-
and
I
were
talking
about
like
maybe
experimenting
with
blender's
3d
blenders,
multiplayer
plugin.
A
B
Yeah
write
it
down
paul.
What
do
you
think
you
could
contribute.
E
I've
run
programming
competitions
in
the
past,
like
college
programming,
competitions
and
so.
B
A
Participants-
and
I
don't
like
how
to
phrase.
E
E
This
is
where
people
start.
You
know.
I
ran
a
programming
competition
in
college
for
the
winter
break
and
we
had
a
reference
bot
that
people
had
to
work
or
do
better
than
actually.
You
know.
Many
of
them
couldn't
do
better
than
our
reference,
but
then
gave
them
the
source
there
for
it
and
they
yeah.
They
were
encouraged
to
build
on
it
and
learn
from
it.
A
A
A
What
would
you
need
to
begin
working
on
that?
Do
you
have
enough
insight
at
this
point?
Yeah
probably
need
more
information
like.
J
The
reward
structure
and
maybe
get
in
line
with
you
know
whatever
the
copy
is
going
to
be
in
the
video
or
the
script.
I
don't
know
if
you
want
the
same,
I
don't
want
to
like
be
repeating
ourselves,
probably
or
maybe
we
do
across
different
videos.
H
A
A
Slide
duplicate
slide
margin
now
with
the
prior
work,
just
there's
something
back
there
that
it
piques
your
interest.
Take
a
look
at
that,
but
it's
you
know
I
document
everything,
so
I
wrote
down
all
the
thoughts
I
had
before,
so
you
can
trace
up
most
of
what
I've
been
thinking
and
it
may
not
be
relevant
or
it
may
be
so
take
it
with
a
with
that
in
mind,
but
I
want
to
do
reward
structure
not
well
judging
criteria.
That's
it's
related
to
reward
structure
of
two
separate
things,
though,.
A
Judging
criteria,
let's
see,
did
anyone
take
reward
structure
yet
because
I
can
tackle
both
of
them
like
the
plain
assets
that
we,
if
we
think
about
a
hero
x,
incentive
challenge.
What
are
you
can
start
by
looking
at
okay?
What's
a
typical
challenge?
Look
like
and
here's
how
they
structure
it
and
here's
the
assets
that
we
need,
because,
because,
literally
right
now,
just
to
separate
the
two
different
phases
phase,
one
is
we're
designing
the
challenge
for
a
posting.
A
You
should
be
careful
about
the
language.
It's
true
polo
was
a
good
thing.
What
do
we
call
it?
We're,
collaborating
and
we're
collaborating
participating,
and
therefore
we
say
that
participation
is
open
to
all.
Do
we
get
to
enter
as
contestants
enter
as
well?
We
should
have
a
name
for
the
people
who
participate
and
to
enter
as
a
participant.
A
The
contributor
are
we
going
to
be
a
contributor,
so
we
call
and
contribute,
and
any
contributor
can
be
graded.
Well,
can
be
judged
for
the
prize,
because
judging
criteria.
F
That's
the
thing
like
with
there's,
not
really
a
precedent
for
like
distributing
a
prize
yeah.
F
H
F
F
There's
like
those
things
would
be
like
like,
for
example,
like
the
godot.
They
have
a
patreon.
They
raise
like
15
they're,
getting
up
to
like
20
000
a
month
and.
F
They
just
hire
people
to
to
fix
the
things
that
no
one
else
wants
to
work
on.
B
B
F
To
develop
that
support
for
x11
on
linux,
because
that's
like
notoriously
difficult
and
it
takes
a
long
time.
A
Okay,
okay,
so
I
have
to
shift
my
thinking
on
that
if
I'm
taking
the
so-called
judging
criteria,
reward
structure-
okay,
that's
good.
I
E
B
I
Yeah
yeah,
but
I'm
I'm
thinking
about
what
to
do
exactly.
I've
basically
do
some
research
because
I
don't
know
much
about
the
technical
side,
but
yeah
I
was.
I
was
thinking
about
the
reward
structure
as.
A
Yeah
well,
that's
kind
of
what
I
was
thinking
about
doing
so
maybe
we
can
share
notes
on
that.
So
there's
some
overlap.
There.
B
I
Like
I've,
there's
incentives
and
like
videos
about
it,
like
that's
one
of
the
two
notes
I
got
about
it:
incentives
in
one
site
and
video
about
your,
but
I'm
not
I'm
not
really
sure
on
like
how
does
the
business
model
kind
of
fit
into
this.
A
A
I
No,
I
think
it's
about
the
collaboration.
B
A
A
A
B
B
A
B
A
Yeah
for
imagery
of
seed
house
prototypes
is
you
can
do
the
our
house
right
now,
it's
looking
quite
nice.
Have
you
guys
seen
it
or
that's
photographable,
that's
that
we
can
set
up
and
then
we
have
to
build
one
which
we
are
right
now
so
yeah.
That
would
work.
I
mean
oh
yeah,
so
some
aerial
photography
on
that
oh
yeah,
that
will
be.
B
Interrogate
here
paul,
are
you
available.
B
B
B
B
A
With
a
big
3d
printer
that
can
print
from
trash
plastic
and
that
can
print
another
cd
ca
home
for
under
ten
thousand
dollars,
so
actually
there's
some
funky
verbiage.
We
can
create
around
that
how
to
create
a
really
compelling
story
around
that
story
of
cleaning
up
plastic
production
distributed
production.
How
does
it
relate
to
housing?
What's
credible,
how
can
we
communicate
it
effectively.
A
A
That's
the
clean
up
the
environment
and
print
a
house
to
print
your
own
house
for
ten
thousand
dollars
or
less
there's
a
lot
of
credibility
that
like
for
me,
I
can
say,
because
I
I
could
see
the
technology
working
on
that
and
for
me
it's
pretty
obvious
that
that
can
happen.
I
think
one
of
the
challenges
will
be.
A
Oh,
I'm
sorry,
sam,
I'm
sorry!
I
was
talking
to
myself.
A
A
Oh
well,
okay,
so
whoever
we
we
came.
We
went
through
a
bunch
of
little
discussion
here,
so
you
can
review
the
video
once
it
goes
online,
but
we're
gonna
say
so
so.
Sam
hearing
you
so
you're
gonna
bring
some
equipment
down
to
when
when
you
participate
here
for
the
three
months
summer,
acts.
D
A
D
Yeah
and
actually
was
mean
to
talk
to
you
about
that,
it's
possible
I
might
be
able
to
free
up
august
and
december
if
I
was
able,
if
yeah,
if
you
wanted
me
to
come
down
for
the
for
that
period
as
well.
A
All
right,
that's
great,
so
yeah
we
can
talk
about
more
details
on
that,
but
that
definitely
would
help
us,
and
because
I
mean
it's
really
about
once
again
showing
for
people
solving
for
people
showing
up
and
enough
energy
coming
into
the
project,
to
make
it
better.
That
I
mean
it's
an
obvious
statement,
but
here's
an
opportunity
and
that's
that's
what
we
intend
to
do
with
with
what
we're
doing
right
now
to
make
it
available
for
people
to
participate
full-time.
A
Ideally,
after
the
apprenticeship
there's,
we
are
actually
getting
geared
up
to
to
open
this
pretty
much
for
a
year
round
operation,
and
so
possibly
some
people
from
the
from
the
event
here
may
stay.
Most
people
probably
may
go,
but
we're
going
to
continue
the
apprenticeship
after
as
well
so
yep.
A
That's
great
and
in
terms
of
today,
do
you
have
some
time
available,
let's
see
like
regarding
some
of
the
the
actual
so
sam,
like
the
photography
and
stuff
like
that.
Are
you
sticking
around
for
the
day
today
or
oh
yeah?
How
long
are
you
planning
on
running
until
we're
gonna
run
till
five?
So
basically
we're
gonna
work
on
like
we're,
trying
to
divide
rolls
up
and
then
actually
get
some
work
done
on
them
and
get
some
meaningful
progress.
A
A
There's
a
it's
called
video
gallery.
Let
me
paste
the
link
for
everybody.
The
video
gallery
is
there
and
it's
got
a
lot
of
topics.
I
mean
there's
so
much
there
there's
starting
in
2008,
so
you
can
just
scroll
through
all
of
that
and.
A
See
a
bunch
of
stuff,
I
mean
there's
some
gems
in
there
and
a
lot
of
stuff
is
just
in
process
stuff
too.
So
maybe
I
mean
actually
one
role
is
actually
organizing
those
assets
as
they
are
like
annotating
them
or
possibly
moving
them
into
galleries
such
as
at
the
very
bottom.
A
You
see
a
gallery
where
I
have
some
thumbnails
of
what
the
videos
and
media
assets
actually
look
like.
So
if
you
want
to
that's,
I
mean
it's
a
task.
If
you
want
to
do
that,
but
start
taking
a
look
at
this
and
see
what
what
what's
relevant,
that
you
can
pull
out
for
like
if
we
have
the
promo
video,
there's,
probably
stuff
on
a
torch
table
or
some
3d
printing
stuff.
A
We
might
have
a
little
bit
on
the
shredder
and
filament
maker
and
stuff
like
that,
so
you
can
start
taking
a
look
at
that,
but
other
than
that,
what
do
you
think
would
be?
You
know,
learning
about
role,
division.
What
do
you
think
like
say
we're
collaborating
like
this?
What's
how
can
there
is
there
a
way
to
synergize
on
that
with
you
today,
as
we,
you
know
we're
working
on
various
assets,
any
thoughts
on
what
what
you
would
you
could
do
today.
D
Well,
not
being
in
person
there.
I
can't
do
any
actual
photography
or
videography
for
you,
but
remotely.
I
can
you
know,
take
a
look
at
those
videos
like
you
said,
and
I
have
a
bit
a
bit
of
graphic
design
experience
if
anything
like
that's
necessary.
If
we
don't
have
an
actual
designer
enough
to
make
some
print
materials
or
you
know,
whatever
else.
K
A
A
Who's
actually
a
pretty
good
graphics.
Guy
too,
we
should
pull
them
in,
but
maybe
I
don't
know
maybe
like
seed
something
cedar
since
we're
starting
on
it,
maybe
seed
something
like
a
logo
or
something
or
I
don't
know.
I
guess.
K
A
A
You
can
take
a
look
at
our
fonts
and
colors
and
stuff.
Let
me
paste
that
in.
D
Yeah
and
in
the
next
month
I'm
gonna
be
sort
of
I'm
gonna,
try
and
participate
in
the
online
as
much
or
digital
participation
as
much
as
I
can,
but
I
will
be
a
bit
spotty
yeah
due
to
internet
connection,
etc,
not
gonna
be
home.
So,
but
as
soon
as
I
can
make
my
way
down
there,
yeah
I'm
whatever
you
guys
need
me
to.
G
D
In
that
case,
it'd
be
good
to
be
looped
in
with
whoever's
working
on
like
the
copy
and
then
copy
marketing
and
branding
for
the
event.
D
B
K
B
K
B
K
A
How
do
we
do
that?
So
if
we
have
some
graphics
assets
we
could
generate,
we
can
maybe,
like
start
passing
around
invitation.
Blurbs.
That's.
K
Like
like
ads,
I
don't
know
if
you've
done
that
before,
but
you
can
run
ads
that
start
to
target
certain
markets
on
the
social
media
platforms
and
you'll
have
more
visibility.
That
way,
rather
than
just
like
my
network
or
the
various
networks
of
the
people
here,.
G
News
because
I
think
this
will,
that
will
give
us
free
advertising
and
a
very
targeted
audience
is
this
first
slide
like
what
needs
to
be
done
or
like
a
list
of
tasks.
Those
like
the
software
pieces,
like
the.
K
Web
website
updates
there's
the
gaming
that
what's
going
to
do,
there's
marketing
and
copywriting
there's
you
know
all
of
any
of
the.
A
Yeah,
it's
just
some
and
I'll
link
to
on
the
pro
in
the
prior
work.
There's
there's
a
bunch
of
stuff
written
there.
So,
for
example,
prior
work,
incentive
onboarding
is
reward
structure.
Okay,
there's
already
a
bunch
of
stuff
there,
so
I
one
thing
we
can
do
is
just
study
that
and
copy
that
into
the
current
work
or
start
wiki
pages
like
if
you
do.
Your
slide,
add
to
your
wiki
pages
now:
who's
who's
logging
in
their
logs.
A
Let's
see
please
log
in
your
logs
because
right
now
it's
going
to
get
into
the
issue
of
like
what
are
people
doing
so
one
way
to
organize.
It
is
okay,
we
have
the
slide,
but
you
can
immediately
go
joshua
log
what'd!
You
do.
I
can
see
what
you
did
today
right,
so
we
can
coordinate
effectively
that
way.
That's
the
purpose
of
the
log
also
try
to
keep
your
hours
if
it's
working
for
you.
A
Place,
oh,
let's
maybe
slide
with.
A
B
L
Yeah
I
placed
mine
into
live
I'll
I'll.
Just
tell
you
the
thing,
because
I
need
you
to
do
something.
B
B
H
A
B
A
L
B
L
B
B
L
Yeah
before
I
started,
I
went
through
the
to
the
wiki
and
I
made
a
video
about
it.
Actually.
B
L
I'll,
actually,
no,
I
I
have
to
upload
it
now.
Oh
please.
A
Yeah
yeah,
that's
great.
A
A
L
D
G
No,
some
headphones
from.
B
B
A
It
up
front
under
yeah.
That's
definitely
useful.
D
L
Okay,
so
this
is
a
tutorial
on
how
to
give
other
people
access
on
your
youtube
channel
without
giving
sensitive
information.
Now
you
go
to
the
youtube
studio
right
and
then
you
go
to
sites,
and
then
you
go
to
permissions.
