A
Hey
welcome
everybody.
We've
got
the
April
third
Tuesday
meeting
of
the
osc
dev
team.
Let's
go
to
the
development
team
agenda
here.
Let
me
share
my
screen
as
well,
so
he
can
follow
where
I
am.
It
looks
like
jitsi
has
changed
a
little
bit
and
jitsi
interface
looks
like
it's
changed
a
little
bit.
Okay,.
A
A
Okay,
okay,
sounds
good,
so
let's
continue
all
right
so
so
agenda
for
today,
progress
reports,
so
I'll
talk
a
little
bit
about
Elysee
developers,
the
personal
microfactory
and
the
long
curve
of
development
and
then
FIRST
Robotics
Oklahoma,
meeting
John's
filling
in
on
a
d3d
Ohio
he's
absent,
ruslan,
more
work
on
a
piping
work.
Bench
Michael
is
working
on
he's
in
the
background
working
on
an
internet
part
on
the
backup
storage
for
OSC.
So
we're
getting
that
all
into
place.
A
Then
Abe
more
work
on
a
power
cube
and
Lex
I
haven't
heard
from
here,
but
he
is
working.
The
long
nice
thread
about
the
filament
maker
and
and
the
plastic
shredder
sets
that's
good.
Let's
see
task
allocation.
Can
we
have
somebody
take
notes
and
aid?
Maybe
you
could
do
that
or
okay
sounds
good,
so
take
notes,
yeah,
yeah,
what's
good,
so
on
always
see,
devs,
hey
I,
just
looked
at
the
sum
of
the
numbers.
A
If
you,
if
you
look
at
the
OSE
developers
page,
we
do
have
people
moving
up
in
numbers,
so
we
have
1
2,
3,
&,
4,
star
developers.
Ie
people
have
completed
the
full
90
day
terms,
two
stars
for
two
of
the
90
30
day
terms:
there's
three
stars,
one
for
star,
so
on
the
one
star
we've
got
Christian
who's.
Still
in
the
background
he's
doing
our
hour.
Oh
I
see
Linux
ISO
IO
he's
not
with
us
anymore,
Joseph,
Dixon,
Hosea,
those
are
all
past
developers
and
to
star.
A
We
have
some
past
people
like
Emanuel
and
Oliver,
and
then
Ruslan
and
Edmund
are
still
where's.
Arman
are
still
on
the
team
and
then
three
star
we
got
Roberto
who's
been
on
vacation
for
some
time
now.
Lex
is
still
on
and
Abe's
going
strong
here
and
four
star
Michael's
been
quite
consistent
back
on
the
internet
issues
and
myself
as
well.
So
that's
that's
where
you
are
right
now:
okay,
team
team
hours
are
looking
at
we're
at
about
like
a
hundred
hours
per
week
or
so
so
definitely
we
want
to
grow
and
grow.
A
The
team
as
I
keep
saying
and
I
think
that's
gonna
happen
once
once.
The
the
immersion
program
is
gonna
happen
and
also
the
hero
acts,
that's
still
in
the
works.
So
that's
all
good.
Now,
as
far
as
the
the
personal
microfactory
are
pretty
much
that's
for
the
immersion
training
program,
that's
what
we
can
offer
right
now,
the
3d
printer
with
some
interchangeable
heads.
So
it's
this
is
the
personal
micro
factory
is
the
basic
small
tools
of
the
of
the
micro
factory.
So
we've
got.
We
definitely
have
the
capacity
developed
for
3d
printing.
A
We
have
not
done
the
laser
cutter,
the
small
laser
cutter
attachment,
there's
plenty
of
that
evidence
and
and
videos
on
YouTube
of
how
to
do
that.
Using
the
same
tool
chains,
clay
extruders
are
still
out.
That
would
be
good
to
add
a
clay
extruder
head
to
the
platform.
There
are
some
clay
extruders
out
there.
I
haven't
really
looked
deeply
as
far
as
how
well-documented
any
of
that
is
I
know
our
friends
from
most
the
Michigan
open-source
tech
lab.
They
have
worked
with
that.
A
So
there's
possibility
there
for
forgetting
that
tech
transfer
happening,
but
that
would
be
you
know
if
you
could
bake
your
own
pots
and
things
and
clay
objects
that
so
so
things
earthenware
or
ceramic
ware.
That's
useful
for
some
parts
and
also
for
practical
applications
like
cups
and
things.
So
imagine,
printing
out
swag
for
people
in
our
open-source
little
everything
store
using
our
own
clay
printer.
A
But
you
have
to
bake
that,
though,
so
there's
a
there's,
a
little
furnace,
that's
needed
for
that,
and
then
the
last
head
here
that
we
have
for
the
personal
micro
factory,
the
scene
seam
circuit
mill
head,
which
is
now
well
developed
and
looking
forward
to
run
a
workshop
on
that
this
year
and
have
that
included
for
circuit
milling
of
all
kinds
of
different
circuits.
So
that's
very,
very
useful,
then.
On
top
of
this,
we've
got
the
plastic
grinder
in
filament
maker.
That's
so
so.
A
Currently,
we've
as
we
said,
the
Thunderhead
tech
for
trade,
one
is
not
available
right
now,
we're
working
still
with
the
Lyman,
which
is
still
a
good
choice
and
and
that
can
produce
a
spool
of
filament
every
every
two.
So
so
in
terms
of
production,
that's
acceptable
like
as
a
minimum
level
of
production.
You
can
have
multiple
ones
of
that
to
actually
produce
filament
for
sale
or
for
use,
and
then
a
price
plastic
grinder.
The
best
one
we
know
of
is
is
from
the
the
precious
plastic
project
by
Dave.
A
Hawkins,
so
that's
that's
one
that
we
can
definitely
use
and
between
David
Hawkins
extruder
and
the
Lyman
filament
extruder
one
comment
I
do
have
is
Lyman
has
only
got
a
1/2
inch
screw,
so
the
limitation
to
that
would
be
the
regularity
of
the
of
the
pellet
feed
like
right
now,
mr.
Lyman
uses
pellets
to
feed
that
they're
very
regular,
but
they're
a
commercial
product.
It's
not
like
you
can
not
sure
how
well
the
Lyman
filament
maker
would
work
with
pretty
much
regrind
or
just
shredded
plastic,
like
from
the
from
the
precious
plastic
shredder.
A
So
one
way
to
move
on
from
the
filament
maker,
the
Lyman
is
to
use
a
larger
screw
so
I'm.
Actually
looking
at
that
here,
using
a
larger
screw,
the
the
the
precious
plastic
uses
a
1
inch
screw,
whereas
the
Lyman
uses
a
1/2
inch
screw.
So
obviously,
if
you've
got
a
1
inch
screw,
you
can
just
press
much
more
through
that
and
and
Dave's
version
the
precious
plastic
one
they
work
with
regrind.
So
that's
good.
They
have
more
of
that
tool
chain
developed.
A
A
A
So
this
you
know
this
is
all
all
work
takes
a
long
time
and
I
just
ran
into
this
thing,
and
the
long
nose
of
innovation
I
was
looking
at
doing
some
internet
searches,
and
this
is
actually
a
useful
thing
for
what
what's
happening
here
like
in
terms
of
how
technology
is
adapted,
because
we
definitely
see
that
at
OSE.
It's
like
it's
taken
a
long
time
to
to
get
started
as
in,
like
only
now.
A
Are
we
getting
to
the
immersion
training
where
we're
trying
to
very
deliberately
get
more
people
going
on
this,
because
by
itself
it's
like?
We
can't
escape
this
invention
area
here.
Invention,
refinement,
augmentation,
it's
a
long
process
and
then
you
start
getting
traction
I
think
to
get
to
that
traction.
That's
where
the
immersion
program
comes
in,
just
more
people
doing
this
full-time.
So
so
we
can
actually
have
a
significant
impact.
A
So
it's
just
a
useful,
useful
framework
because
development
does
take
long
time
and
if,
unless
you
get
those
final
steps
of
refinement,
you
always
be
like
in
this
invention
and
refinement.
Augmentation
stage,
like
you
know,
like
with
our
power
cubes,
for
example,
I
mean
we've
been
going
through
so
many
different
versions,
but
that's
just
the
reality
of
the
game.
It's
it's
to
get
something
to
from
a
project
to
a
product.
That's
a
lot
of
iteration.
So
it's
just
a
useful
framework
to
look
at
okay,
a
quick
report
from
the
FIRST
Robotics.
A
This
is
that
we
went
Katrina
and
I
visited
FIRST
Robotics
in
Oklahoma
I.
Don't
have
I,
didn't
upload
pictures
I'll
do
that
later,
so
we
spoke
there.
We
actually
gave
versions
of
our
TED
Talks
there
to
an
audience
of
1,100
students.
The
event
was
really
nice.
A
lot
of
the
students
there
are
quite
quite
savvy.
It
was
kind
of
like
a
bit
basically
like
a
big
hackers,
fest
kind
of
a
deal.
They
make
robots
that
don't
have
like
really
much
meaning,
but
they
do
have
great
educational
value.
A
So
that's
a
great
way
to
prototype.
If
we
get
their
team
of
students
going,
then
that's
something.
That's
a
totally
collaborative
effort,
a
team
of
people
outside
of
factory
farm.
You
get
to
do
that,
make
some
improvements,
and
that
would
be
great,
we'll
see
if
we
could
get
them
going
on
free
cat
or
not
I
mean
we'll
see
we'll
see
if
they're
up
for
that.
But
that's
that's
one
good
outcome.
A
There's
a
lot
of
sort
of
contacts
I
made
were
with
like,
for
example,
the
tech
there's
tech
centers
in
Oklahoma,
then
Oklahoma's
actually
six
hours
away
from
us.
So
it's
a
little
bit
of
a
drive,
but
they
have
tech
centers
and
there
is
definitely
problem
possibilities
of
with
the
people
that
we
met
there
to
promote
policy
projects
to
students.
So
that
was
a
the
interesting
thing.
A
There
was
that
a
lot
of
the
people
there
were
very
quite
very
much
interested
some
professors
from
universities
who
are
involved
in
first
several
contacts
them
following
up
with
right
now
regarding
having
students,
do
that
for
student
projects,
master's
thesis
and
there's
possibly
like
we
typically
look
for
things
like
master's
thesis.
That's
an
excellent
thing
cause.
A
You
know
that
a
student
has
to
put
in
a
lot
of
hours
to
some
development
and
why
not
actually
work
on
something
very
meaningful
like
what
we're
doing
or
for
even
for
the
tech
centers,
which
are
basically
kind
of
like
technical
education
for
students.
They
have
projects
projects
where
it's,
where
a
team
of
three
students,
for
example,
works
for
eight
months.
So
once
again
there
that's
that's
a
great
opportunity
for
having
some
serious
traction
on
develop.
So
that's
it.
A
That's
in
the
in
the
works,
we'll
see
what
what
comes
out
of
this,
but
definitely
I'm
interested
in
going
back
down
there.
At
the
very
least,
to
present
to
one
of
these
tech,
centers
and
they've
got
many
of
those
that's
kind
of
unique
how
it
works
in
Oklahoma
that
the
way
they
have
the
tech
sensors.
It's
not
community
colleges.
It's
not
high
schools,
it's
somewhere
in
between,
but
it's
kind
of
a
unique
structure.
They
have
down
there.
A
We
could
go
down
there
and
so
possibly
do
a
thing
like
okay
run
a
3d
printer
workshop
and
then
do
a
presentation
so
that
we
can.
We
can
get
both
people
building
3d
printers.
As
well
as
running
well,
possibly
joining
the
dev
team
or
or
some
student
project
version,
so
that
was
that
was
pretty
good.
I
like
that
even
was
quite
inspiring.
Was
it
was
quite
nice
to
see
that
kind
of
excitement
from
the
students
there.
These
definitely
were
all
kind
of
like.
A
Definitely
you
can
see
how
the
leadership
qualities
in
these
these
young
students
was
we're
being
cultivated
as
they
work
on
the
teams
together
and
projects,
those
very
nice
environment,
okay.
So
let's
move
on
so
John's
log
here,
let's
see
what
he's
up
to
he.
He
can't
make
the
meeting,
but
let's
see
what
he's
got
so,
let's
see
built
the
d3
single
d3
axis,
working
on
a
CAD.
A
Yeah,
we
should
definitely
do
so
he's
ready,
getting
ready
for
the
build
and
definitely
wanna.
We
want
to
review
the
CAD
to
see
where
we
are
on
the
quality
control
on
the
CAD,
so
make
sure
we're
building
a
right
thing.
That's
actually
gonna
work.
Some
thoughts
expect
to
be
able
to
remotely
see
the
status
of
manage
my
factory
so
yeah
management,
so
that
would
be
the
like.
I
mentioned
on
slide
4.
There's
the
Arduino
controller,
Raspberry
Pi
wireless
control,
open
source
power
supply
the
Raspberry
Pi
wireless
control
is
something
we
can.
A
A
Yeah,
continuous
bed
printing-
that's
something
to
consider
for
the
future
that
basically,
when
you
print
like
a
like
on
a
45
degree
angle,
there's
3d
printers
that
they
basically
have
a
conveyor
and
you
print,
and
they
they
it's
a
totally
continuous
print.
So
you
can
print
forever.
That's
something
to
look
at
in
the
future.
Perhaps
yeah
products
pop
out
the
other
and
the
other
side
of
that
is
having
automatic
part
harvesting.
A
If
you
have
a
print
bed
and
a
finished
part,
you
can
simply
like
bump
it
off
or
have
a
small,
robotic
arm
like
there's
a
lot
of
small,
robotic
open-source,
robotic
arms
out
there,
maybe
have
a
small,
robotic
arm
actually
pick
it
off.
I
was
looking
at
trainable,
robotic
arms,
which
basically
you
touched
the
arm
and
you
around,
and
that
arm
memorizes
what
you
moved.
So
you
can
actually
train
it
by
physically
touching
that
arm
and
moving
it.
How
you
want
to
do
that
want
to
be
moved?
A
That's
a
great
interface
moment
like
if
we
can
get
to
that
yeah.
Definitely
points
of
development
and
on
robotic
arms
and
3d
printing
working
together,
open
source
and
wheel
base,
POC
programmable,
logical
controller.
Some
can
program
with
ladder,
logic
or
Broten
block
diagram,
I'm,
not
sure
what
that's
referring
to
cuz
I
mean
that
we
already
have
open-source
Arduino
controlling
the
whole
system,
but
ok,
all
right,
hey!
Do
you
wanna,
continue
on
the
power
cube
where
you're
at
right
now.
B
A
D
D
B
B
B
D
B
You
create
solid,
then
you
cannot
modify
the
day
tomorrow,
flamingo
and
then
performing
that
limitation
allows
you
to
change
the
parameters
and
then
there
is
a
final
code
which
will
redraw
it.
The
only
disadvantage
now
with
one
implementation
elemental,
but
my
implementations
in
experimental
stay
with
the
soliton
parts.
When
you
save
it
you
you
are
dependent
on
my
implementation.
D
B
D
B
D
So
guess
one
board
man
there's
how
hard
I'm
absolutely
using
Python,
it's
tough
to
do.
Creating
the
workbench
you're
drawing
up,
gets
GUI
interface
stuff.
Is
it
much
harder
to
move
from
like
doing
CSV
to
maybe
doing
something
more
complicated
with
the
GUI,
where
you
can
enter
more
data
to
generate
the
parts
like
just
by
entering
the
data
with
the.
B
D
You
know
obviously,
and
draw
them
with
different
methods,
so
some
are
more
edible
than
the
others,
but
it
would
almost
be
nice
in
some
cases
to
have
a
well
a
macro
that
in
co2,
but
just
to
be
able
to
have
like
a
tool
that
would
draw
a
bunch
of
different
parts
by
entering
or
simular
parts
by
entering
different
dimensions.
You
know
right
into
a
into
a
one,
don't
think
Julian
freaking
if
it
could
any
welcome
everybody
now.
D
D
D
The
National
pipe
thread
standard,
okay,
you
know
which
I
guess
it's
materials
Danner,
but
yeah.
It's
used
for
the
metal
pipes
before
and
I.
Don't
know
how
detailed
to
get
with
that
I
know
some
of
the
apt
parts.
They
even
have
the
taper
up
threads
because
the
threads
in
the
apt
are
actually
you
know,
taper
what
these
parts
I've
been
trying
to
haven't
done
that,
but
I
don't
know
how
hard
that's
it
well,
obviously,
we
don't
want
to
draw
them
threatened
too
much.
D
Other
people
think
the
only
reason
to
vote
the
detail
of
things
like
the
caper
and
all
in
the
future
was
was,
if
eventually,
some
machines
are
made
to
actually
machine
some
of
the
stuff
right.
So
that's
not
an
immediate
priority
for
that.
Much
detail
so,
but
it'd
be
nice
to
be
able
to
end
woman.
Some
of
that.
D
Okay,
so
yeah
I
guess
this
power
keep
you
still
get
some
plumbing
details
but
kind
of
slow
on
that
puppy.
I.
Think
it's
pretty
close
before
the
next
about
the
tractor
figure
issues.
It's
looking
back
at
I
gotta
go
back
to
do
more,
follow
work,
I'm,
pretty
close
on
the
cat
stuff,
but
putting
the
cat
so
up.
First,
results
in
issue
I.
Think
last
week
we're
talking
about
the
file
management
just
like
the
template
and
everything
getting
to
burn
down
right,
yeah.
E
D
Sometimes
it's
things
change
I'm
gonna
actually
try
to
concentrate
more
on
cleaning
up
some
black
file,
stuff
figuring
that
out
because
the
cab
gets
done,
but
the
other
stuff
is
a
lot
more
technical
details
figured
out
in
there,
so
I
think.
There's
a
page
I
think
marching
last
week,
you've
hit
a
page
up.
Don't
we
give
up
managing
up
files
for
the
burn
down
so
I'll?
Look
into
that
more
now,.
D
D
A
D
D
A
D
A
A
A
A
Can
take
I
mean
all
right,
I
mean,
but
why
is
that
I
mean
I'm,
not
really
seeing?
How
is
that
difficult
I
mean
I,
say:
you've
got
3d
CAD,
you
know
you
just
give
it.
The
general
amount
like
if
it's
totally
complete
it's
ten.
If
it's
just
started
it's
one
and
then
it's
somewhere
in
between
I
kept,
you
think
you're
halfway,
it's
like
five.
You
know
just
kind
of
estimate.
The
percentage.
D
A
I
mean
what
I
was
saying
is
that
yeah
I
mean
I
mean?
That's
that's
true
like
if
you
think
that
you
were
complete,
but
but
you
discovered
something
along
the
road
that
makes
it
no.
This
has
actually
got
a
lot
of
work.
I
mean
that's,
that's
how
it
could
that's,
how
it
could
change,
but
it's
just
kind
of
still
qualitative.
D
A
Yeah,
that's
yeah
exactly
exactly,
but
that's,
but
that's
the
point
I
mean
yeah.
You
have
to
keep
track
of
that
very
carefully.
Like
I
mean
this.
Is
this
this
development
template
is
very
information-rich.
You
can
click
on
each
link
and
then
you
have
to
see.
What's
in
there,
so
I
mean
there's
no
shortcut
to
really
managing
this
properly.
I
mean
there's
just
so
many
different
tasks
need
to
be
done
and
tracked.
A
D
A
I
mean
that's
the
issue
like
we
do
some
work
and
and
then
we
might
not
update
the
development
template,
but
that's
that's
the
that's.
A
discipline
we
have
to
build
up
is
that
we
go
where
whatever
exists
is
represented
in
the
template.
Otherwise,
I
mean
the
template
should
be
a
place
where
you
say:
okay,
if
it
doesn't
exist
in
there.
That
means
it's
not
done.
It's
supposed
to
be
that
summery,
but
yeah
I
mean
point.
A
A
A
Let's
see
what's
under
that
right
now,
yeah
I
mean
that's
it's
a
big
page,
yeah
yeah.
That
needs
to
be
a
that's
a
lot
of
old
hump
man
tell
me
about
it,
a
lot
of
old
stuff.
It's
got
like
all
the
theory,
but
but
as
far
as
actually
doing
it
I
think
we
have
to
settle
on
okay,
here's
a
basic
procedure
for
all
the
developers.
You
know
like
okay,
just
summarizing
the
main
points
that
need
to
be
be
there.
D
A
I
think
what
would
we
need
is
something
like
a
developer's
manual.
You
know
here's
your
operations
manual
for
when
you're
a
developer,
what
you
should
do
just
making
sure
that
you
do
on
a
regular
basis,
yeah
yeah,
we
need.
We
need
to
update
some
of
that.
That's
some
of
the
stuff
I
want
to
update
for,
like
once
we
get
the
immersion
program,
so
we're
very
clear
on
that
and
all
that,
if
you
want
to
take
a
stab
at
it,
stab
at
it,
go
ahead,
but
yeah.
A
D
A
D
C
A
B
E
B
B
A
So
I'm
gonna,
Leslie
piping,
workbench,
you
know
say
I
want
to
try
to
do
the
do
something,
let's
say
create
coupling,
so
I
should
be
able
to
like.
Actually
let
me
show
you
one
I
was
I.
Think
I
was
doing
this.
One
sweep
elbow,
do
an
8-inch
one:
okay,
I
pressed
okay.
What
happened
here,
I'm,
not
seeing
anything,
is
that
above
now.
E
B
B
B
A
B
A
A
B
B
B
B
B
A
B
B
B
B
A
B
A
B
B
B
B
B
B
B
A
A
C
A
A
A
A
A
B
A
B
B
A
B
A
B
A
A
B
B
B
A
B
B
A
B
A
Now
it
is,
there
is
a
lot
of
options,
but
I
mean
it,
for
example,
would
be
useful,
I
mean
I
could
see
cases
where
say
you
got
a
cross
and
you
just
want
little
outlets
on
the
top
and
bottom
the
non-symmetric
crosses
they
would
be
useful
sometimes,
but
yeah.
You
really
do
have
a
lot
of
options.
There.
B
B
A
A
B
A
A
A
B
A
A
B
B
G
A
Serial
numbers
typically
apply:
don't
they
typically
apply
more
to
larger
products
when
you're
say
manufacturing
and
then
you're,
just
keeping
track
of
which,
which
of
the
same
you're
manufacturing,
which
which
are
the
same?
It
is
so
it's
more
for
record-keeping
of
inventory
and
stuff
like
that,
yeah
like,
for
example,
once
we
have
a
bunch
of
3d
printers
that
we're
producing
out
there,
we
should
put
a
serial
number
on
them
so
that
we
know
who
has
what
copy
of
the
Machine.
You
know
what
what
version
correspond
to
the
time
which
corresponds
to
versions
probably
yeah.
H
H
A
A
Yes,
yeah
there's
a
lot
of
lot
of
luck.
There,
probably
the
biggest
most
important
is
the
loader
arm
geometry,
told
the
proper
cylinder
mounting
and
then
the
mounting
of
the
tensioner
/
motors,
which
we
completely
kind
of
well,
not
completely,
but
we
definitely
change
that
mm-hmm
because
of
spacing
issues.
Yep
ya
know.
If
you
speed
up
time.
H
H
H
H
A
I
mean
haven't
used
it,
it's
I
mean
it's
been
pretty
much
winter,
this
whole
time,
so
we
haven't
been
using
it,
but
yeah
I
mean
last
fall.
It
was
was
good,
it's
pretty
good
I
mean
it
wasn't
any
issues.
One
thing
I
was
one
actually
one
weird
thing
was
when
curling,
when
releasing
the
bucket,
somehow
the
bucket,
like
one
cylinder,
would
go
down
and
the
other
one
wouldn't
and
I
act.
I
could
not
still
could
not
figure
it.
What
what
that
was?
A
A
That's
the
that's
the
other
thing
we
talked
about
that
would
be
they
don't
like
to
make
it
totally
like
product
level.
I
do
want
that.
That
part
where
you
can
literally
like
just
spin
in
place
I
think
that's
important
for
some
tight
when
you're
in
a
tight
space.
That's
I
think
that's
pretty
important
so
that
the
part
of
having
more
torque
would
be
one
thing
to
resolve
as
well.
A
A
So
after
the
bucket
was
in
place
and
this
platform
couldn't
couldn't,
do
it
anymore,
if
I'm
just
I'm
standing
on
it
on
the
platform
with
the
bucket
couldn't
do
the
360s
in
place
so
I
think
it's
just
marginally
a
little
bit
too
little.
Torque
and
I
know
that
when
that
happened,
the
machine
would
stall.
A
Now
are
nice
and
inexpensive
and
pretty
good,
so
I,
don't
know
if
we
can
find
we'd
have
to
just
start
another
search
for
parts
we
wanted
to
change
motors,
but
I
mean
we
should
we
should
try
to
make
it
work
with
what
we
have
since
we've
got
experience
with
these
already
so
to
go
to
the
next
motor.
That
would
involve
more
testing
and
complication.
H
H
H
H
A
Does
add
a
lot
more
complication,
but
I
mean
that's.
People
do
do
that.
The
good
thing
about
Hydrox
is
the
motors
are
strong
enough.
You
don't
really
need
that.
Gearbox
I
mean
that's
the
advantage,
because
otherwise
that's
a
wearable
part,
so
that
definitely
would
not
be
preferred.
If
we're
gonna
go
to
a
gearbox.
I'd
would
rather
look
for
another
motor.
You
know
I.
A
H
A
Well,
I
mean
to
change
it
on
a
go.
You'd
have
to
have
the
lever
for
the
flow
control
valve
in
front
of
you,
and
then
you
would
just
change
that
to
change
the
speed
as
you're
going,
but
you
typically
don't
need
to
change
speed
as
you're
going
well
I
mean
that
depends
what
you're
doing.
If
you
do
want
to
change
in
mid-course.
A
H
A
We'd
have
to
look
at
the
exact
numbers
like
we
say.
Okay,
if
you
got
there's
simple
formulas
that
you
say:
if
you
got
such
a
size
of
a
motor
based
on
such-and-such
flow,
it
will
spin
so
fast.
So
we
have
to
go
through
that
and
based
on
what
we
know
right
now.
We
we
know
that.
Okay,
the
current
speeds
are
good.
A
Like
you
know,
we
know
that,
let's
say
about
like
two
miles
per
hour:
that's
a
really
good
speed
or
like
4
miles
per
hour.
That's
pretty
fast
for
a
machine
like
this,
but
if
you
get
down
to
like
half
a
mile
per
hour,
okay,
that
might
be
pretty
slow,
so
you
have
to
look
at
actually
all
those
numbers
and
kind
of
scratch,
our
head
and
and
see
what's
best,
but
right
now
definitely
would
be
advisable
to
go
from
the
eight
to
six
that
we
can
possibly
do
that
as
step.
A
One
we
say:
okay:
now
we
just
needed
more
torque
on
a
turning
part,
so
we
we
get
the
30%
more
by
going
from
eight
to
six
and
that
might
solve
it.
And
then
we
can
say:
okay,
this
actually
works
good,
and
if
not,
then
we
would
go
to
to
a
smaller
pump,
which
would
be
just
slightly
slower,
but
would
give
us
more
torque
and
wouldn't
stall,
because
because
right
now
it's
actually
stalling
when,
when
I
do
the
360
in
place
yeah.
So
it's
just
it's
like
marginal.
It's
I
mean
10
20,
30
percent.
A
A
H
A
A
Okay,
so
you
got
a
3,000
psi
pump.
You
just
got
one
of
them.
Pressure
is
the
important
part
like,
for
example,
the
tiny
power
cube
which
tom
was
working
on,
which
is
just
the
solar
panel
based
one.
It's
got
a
very
tiny
pump,
but
it
still
produces
3000
psi.
That's
the
beauty
of
it
yeah.
Typically,
they
you
get
that
high
psi,
so
you
can
still
that
little
power
cube
can
drive
an
entire
tractor,
but
it's
very
slow,
very,
very
slow,
but
that's
the
that's
the
whole
point.
A
H
A
H
A
H
A
A
A
H
A
G
C
H
A
A
Okay,
you
missed
that,
but
the
point
about
the
open,
the
personal
micro
factory.
So
the
idea
is
that,
just
with
a
3d
printer,
a
small
laser
head
like
a
four
or
five
watt
laser
a
four
watt,
laser
can
actually
cut
1/8
inch,
wood
or
like
cardboard
between
3d,
printing
and
laser
cutting
of
cardboard.
You
can
actually
make
an
entire
mock-up
of
this
thing.
A
There's
a
page
on
the
wiki
I
believe
it's
called
OC.
Let's
see,
oh
I
see
rapid
prototyping,
but
the
point
is
before
the
the
proper
thing
to
do
to
make
sure
that
everything
works
now,
given
that
we
know
exactly
what
the
motors
are
cuz.
That
was
the
big
question
from
last
time
that
we
just
didn't
have
a
good
file
for
the
motor.
A
Take
a
look
at,
for
example.
Obviously,
rapid
prototyping
I
show
the
ok
look
at
this
link
here,
but
the
flat,
cutouts
and
I
show
that
on
the
bottom
there,
the
flat
cutouts.
So
while
you
can,
for
example,
prototype
the
CB
press
out
of
flat
cutouts
of
plywood
laser-cut
or
you
can
do
like
the
laser
cutting
of
the
little
materials
of
basically
paper
or
cardboard
or
wood,
and
you
can
make
an
absolute
complete,
accurate
model.
That
would
be
the
proper
thing
to
do
so.
A
We're
not
wasting
any
metal
or
time
and
that's
why
we
actually
want
to
do
the
the
small.
My
personal
micro
factory.
One
of
its
function
is
not
only
that
you
can
do
them:
3d,
printing
or
little
laser
cutting
or
like
the
CNC
circuit
milling,
but
that's
relevant
to
real
scale
model
prototyping,
and
that's
how
we
can
involve
a
lot
of
people
remotely
I
mentioned
in
another
meeting.
That
we'd
also
like
to
start
physical,
like
design
jams
or
like
extreme
design
Sprint's.
A
Where
we
go
to
a
location.
We
have
these
3d
printers
laser
cutters.
Maybe,
since
these
circuit
mills
we
built
some
of
those
and
then
we
can
prototype
real
stuff,
so
between
freecad
and
and
scale
prototyping,
we
can
get
a
lot
of
accurate
models
prototype
and
then
we,
when
we
build
it,
we
just
minimize
the
number
of
surprises
that
come
about.
So
that
would
be
the
proper
way
to
go
about
a
prototyping
effort.
A
So
I
mean
one
thing
that
I
would
really
suggest.
I
mean,
if
possible,
is
that
you
would
build
yourself
the
the
be
3d
or
get
your
hands
on
a
3d
printer
and
a
small
laser
head
on
top
of
a
3d
printer.
We
can.
We
can
retrofit
that
readily
there's
a
lot
of
info
on
that
on
the
internet.
So
that's
something
that
all
of
our
devs
should
have
eventually
and
and
I
think
it's
kind
of
a
priority,
because
that
that
way,
whenever
we
build
something
we
are,
we
were
ready
to
do
it.
H
H
H
A
Yeah,
the
metal
frame
is,
and
one
off
it
might
cost
more,
but
you
can
do
it
in
the
the
PVC,
which
is
we're
going
forward
with
that
John
is
working
on
a
PVC
version.
We
just
really
got
to
test
it
and
make
it
we
know
we
could
make
it
work
it's
we
might
have
to
strengthen
it
even
by
doing
like
filling
it
with
cement
or
something,
but
that
should
be
quite
workable.
H
H
A
Yes,
that's
that's
yeah!
Definitely,
that
would
be
if
you've
got
a
MIG
welder
for
someone
who's
versed
at
welding
or
spot
welding,
even
yeah,
that's
absolutely
doable.
Then
you
can
have
strip
that
you
can
buy
locally
and
at
that
point
the
material
waste
is
zero,
except
the
advantage
of
the
CNC
cut
route.
Is
you
can
do
the
holes
if
you,
if
you're,
attaching
the
axes
not
by
magnets
but
by
my
bolts,
then
you
can
get
the
bolts
in
there
with
the
CNC,
so
Souza's
advantages
and
disadvantages,
but
definitely
for
a
low
cost
version.
A
H
A
Yeah
that
would
be
recommended
to
try
to
I
mean
it
would
take
much
more
time
to
build
the
frame
because
you
got
a
now
instead
of
having
that
cut
by
by
a
CNC
shop.
You
have
to
first
cut
the
pieces
to
length
and
then
weld
them
together
so
and
then
grind
that
stuff.
So
it's
gonna
be
much
more
time,
but
but
it's
worth.
A
H
A
Right
exactly
and
that's
that's
why
it
took
much
longer
than
its
then
it
could,
but
it's
definitely
doable
and
we
should
document
like
for
say
we're
building
the
3d
printer
frames,
which
are
very
uniform
they're.
You
know
they're
all
the
same
pieces
there,
then
it's
worth
knowing
how
much
time
that
takes
you
know
compared
to
okay.
How
much
does
it
take
to
cut
a
frame
on
a
CNC
torch
table
versus
how
how
much
by
hand
using
the
strips?
A
A
Yeah,
because
we
never
really
got
to
that
point
of
actually
drawn
that
that
that
needs
to
be
updated.
So
maybe
if
you,
if
you
do
do
that,
we
don't
have
a
version
where
we
actually
show
the
the
hole
locations,
because
all
the
frames
we
got
before
we
were
using
using
magnets
to
do
that,
and
then
it
turned
out
people
really
hate.
The
magnets
I
mean
that's
just
after
a
couple
of
those
workshops.
People
just
could
not
do
the
magnets
cuz.
A
They
would
jump
out
on
you
it's
too
hard
to
put
them
in
so
so
definitely
we
want
to
do
a
bolt
hole
through
the
frame
so,
but
we
just
didn't
get
to
the
cat
of
that.
So
if
you
could
do
that,
no
be
it
would
be
good.
So
that
means
an
accurate
model.
The
key
part
to
the
modeling,
which
is
what
going
with
jonathan,
is
working,
not
John
Jonathan
but
John
John
is
working
on
that.
A
But
the
key
point
is
to
make
sure
that,
after
everything
is
said
and
done,
you
can
tell
from
the
cat
exactly
how,
where
the
nozzle
moves
to.
So
you
can
know
exactly
what
what
area
print
area
you
have
available?
That's
the
that's
the
tricky
part,
because
you
can
definitely
build
it,
but
then
you
you'll,
find
out.
H
A
Are
still
issues
on
that
like
on
the
wall
on
the
previous
version
that
was
kind
of
easy
because
we
could
shift
the
axis
to
there
mathematically
connected.
So
we
just
shifted
like
from
side
to
side
a
little
bit
and
then
we
would
make
it
fit,
but
definitely
like
on.
If
we
have
the
8
inch
version
yeah,
you
have
to
work
that
out.
Definitely
we're
not
using.
We
don't
have
the
optimized
version
right
now.
A
You
can
make
little
changes
in
the
design
like
we
use
little
spacers
and
things
like
that
to
make
it
fit
better,
but
that
we
have
not
optimized
for
for
print
area
like
the
complete
optimization
from
print
area,
we
might
be
missing
like
an
inch
on
one
side
or
something
like
that
or
an
inch
on
the
other,
and
if
we're
doing
right
now,
we're
also
doing
the
12
inch
print
bed
version.
So
that's
a
totally
different
story
than
an
8
inch.
So.
H
H
A
H
H
A
A
A
A
Okay,
well,
it
sounds
good,
so
yeah,
that's
yeah!
That
sounds
good,
so
yeah.
If
you
could
get
back
right
into
it,
that
would
be
awesome
and
we
can.
When
we're
ready,
we
can.
We
can
take
a
look
at
a
date
for
a
build
and
then
yeah.
So,
let's,
let's
cut
it
off
here
and
then
the
next
meeting
next
week
same
time,
Tuesday
at
2:00
p.m.
so
we'll
see
you
there
guys
thanks
a
lot.
