It
could
be
practical
with
solar.
Only
awesome
now
I
just
got
an
idea
about
the
heat.
So
for
this
version
we
were
talking
about
the
Descent
Abe
last
meeting,
we're
talking
about
the
separate
power
cube
with
parking
that
has
a
separate
engine
and
a
separate
hydrolytic
/
cooling
part.
Well.
Why
don't
we
take
that
cooling
part
with
the
fan
and
make
that
the
cab
heater?
So
if
you
have
those
two
things
separate,
that
makes
it
easier
for
the
heater
part.
So
maybe
we
could
think
about
that.
How
that
could
be
done?
Cuz?
C
Definitely,
the
power
cube
has
got
the
high
drop
reservoir
and
the
engine
next
to
each
other.
But
if
we
make
those
two
modules,
it
doesn't
matter
where
we
put
one
popular
with
module,
which
in
a
winter
could
be
a
heater
right.
It's
just
like
the
heating
in
your
car.
It
works
by
a
heat
exchanger
from
the
fluid
radiator
fluid
here.
We'd
have
this
this
hydraulic
thing
with
a
fan
on
it
that
could
be
blowing
hot
air
inside
the
cab.
So
something
like
that,
so
he
can't
be
the
hydraulic
cooler
parts:
hey.
B
D
C
In
the
chat
box
and
we've
got
Nathan
Jenn,
Abe,
Katarina,
Katie
myself,
okay,
so
go
to
the
document
in
the
chat
box.
Let's
talk
about
so,
let's
just
start
getting
right
down
to
it.
First,
let's
list
all
the
parts
and
on
the
wiki
page,
the
part
library
is
seated.
So
as
soon
as
we
have
files,
we
upload
them
to
the
part
library.
So
first
we're
gonna
get
to
get
there
on
okay.
C
What
are
all
the
parts
here
so
so
to
make
a
copy
of
those
bubbles
and
start
putting
things
in
so
Motors
motor
mounting
play
start
listing
components
if
you
wanted
in
there
put
it
in
there
we'll
draw
it
up
and
the
idea
is
it's
modular.
So
we
can.
We
can
or
cannot
include
things
as
needed,
so
people
yeah
go
ahead,
start
making
copies
of
this
stuff
and
adding
items.
That's
collaborative
development.
C
Now
what
you're
seeing
here
is
OSC's
somewhat
pathetic
way
to
do
collaborative
developing
we've
been
at
it
for
some
time
we're
developing,
like
what
you
see
is
somewhat
of
a
prototype
process
of
how
we
can
work
together,
but
we're
working
towards
the
fact
like
that.
The
key
thing
is
people
the
number
of
people
that
show
up
and
how
many
of
those
people
know
the
basic
collaborative
literacy
on
a
development
process
and
freaking.
C
C
We're
kind
of
plateauing
like
we're
going
on
like
yearly
cycles
of
higher
development
of
some
are
shutting
down
for
the
winter
up
and
down,
but
it's
not
growing
exponentially
you're
growing,
yeah,
it's
kind
of
dawn,
but
I'd
like
to
see
that
graph
of
developer
numbers
way
up
and
through
designs
trends
through
the
real
co-op
additions
through
design.
Sprints
like
this.
C
So
that's
a
little
little
advertisement
for
this
with
incentive
challenges,
because
one
of
the
things
that
are
an
issue
for
the
project
I
think
our
retention
no
kidding,
there's
very
few
people
that
stick
with
a
project
for
years
upon
years,
there's
only
a
handful,
whereas
many
people
just
kind
of
come
and
go.
So
it's
important
to
keep
the
interest
up
and
so
forth.
Okay,
but
with
my
book
coming
up,
oh
yeah
I.
Think
that's
gonna.
C
C
C
Why
cuz
you
want
this
thing
to
stop
when
you
let
off
the
the
speed
like
you,
don't
want
to
park
on
a
hill
and
keep
rolling
down
the
hill,
which
is
what
you'll
do.
If
you
don't
have
cylinder
valves,
because
motor
valves
they
spent
freely
that's
insights
on
the
hydraulics.
Okay,
it's
two
frames
where's
that
hitch
pitch
roll
cage,
roll
cage
is
gonna,
be
the
frame
because
we're
gonna
do:
let's
do
a
power
Q
black
frame,
it's
a
thing
that
it
closes.
The
whole
thing
frame
has
a
roll
cage.
C
C
Yeah
we
can
actually
for
the
art
library
we
can
put
in,
like
the
whole
power
cube
library
in
there
just
to
make
it
all
in
one
place
and
therefore,
if
we
have
all
these
parts
here,
you
can
modify
this
to
make
your
own
make
your
own
different
versions
of
this
golf
cart
because
there's
different
versions
of
golf
carts,
you
can
make
one
that's
like
long
like
ten
we've
we've
seen
that
there's
the
goal
from
anywhere
like
seven
to
like
twelve
feet
or
something
like
that
bad
wow.
That's
so
many
parts.
B
C
B
C
D
C
C
Controls
electrical
diagram
right,
left,
throttles,
okay
for
controls,
we
okay,
electrode
diagram,
that's
a
thing
that
comes
up,
but
it's
starter,
switch
for
the
controls,
there's
gonna
be
a
starter
switch
which
is
going
to
be
connected
to
the
engine
which
is
gonna.
Have
engine
start
both
like
Poole
will
start
an
electronic
electric
start
right.
Let
throttle
is
the
valves.
C
B
D
C
D
Yeah
couple
yeah
sounds
good
R.
C
C
D
C
C
C
C
You
can
also
learn
freak
out.
If
you
can
download
freak
out
16
telling
you
it
could
possibly
do
it
in
an
hour
with
my
brand-new
video
from
last
year,
so
I'm
gonna
put
a
link
to
that
it's
under
freak
out
101,
and
it
wasn't
that
email
freak
out
101
in
the
video
number
three
take
a
look
at
that
workflow
tutorial
draw
things
in
sketcher,
extrude
them
to
3d,
and
you
can
make
as
complicated
things
as
you
like
everything.
C
You
need
for
this
project
that
we're
working
on
right
now,
so
I
put
that
link
on
page
one
free
tutorial
accident.
If
anyone
ever
uses
that
tutorial,
let
me
know
if
it's
any
useful,
how
we
can
make
it
better
cuz
I'm
trying
to
do
is
that
standard,
OSC,
workflow,
that's
always
used
and
how
we
work
here.
So
freecad
tutorial.
C
Idea
is
that
if
you
can
draw
like
you,
could
you
can
make
lines
on
a
two-dimensional
screen
and
then
you
can
extrude
them
and
then
you
can
make
further
shapes
on
each
face.
You
can
get
to
infinite
complexity
and
3d
CAD,
so
the
success
of
a
mass
collaboration-
and
this
would
be
if
if
a
lot
of
people
would
learn
how
to
do
that,
and
then
we
can
turn
ideas
and
the
real
technical
designs.
C
Okay,
I
want
to
do
the
frame
because
there's
a
trick
to
the
frame
cab
frame
so
frame
I
think
that
we
did
that
twice.
I
think
that's
cab
frame,
so
I'm
going
to
put
my
name
on
that.
F
F
A
D
D
So
like
it's
it's
this
component,
that's
made
up
of
all
these
other
actual
parts
and
it's
good
to
just
draw
those
and
make
it
in
the
cab
the
way
it
might
actually
be
built
or
machined
and
manufactured,
because
that
actually
also
makes
sense
in
the
long
term,
and
it's
just
a
convenient
way
to
think
about
breaking
stuff
down
to
dry
in
pieces.
Okay,.
C
You
got
Nathan
Nathan.
How
can
you
take
one
of
these
things
on
it?
Let's
see
so,
okay
on
motor.
Let's
look
at
how
much
data
we
got
on
the
motor,
so
we
click
on
that
and
go
to
surplus
Center,
which
is
the
source.
So
when
you,
whenever
sometimes
a
little
frame
around,
it
means
it's
hyperlinked,
that's
the
OSE
Convention,
of
course,
if
you
go
there,
I
will
be
looking
for
a
diagram.
That's
typically
to
have
parts
like
we
need
some
diagrams.
So,
let's
see,
then
they
have
this
questions.
Warranty
info.
C
C
C
Anthony,
here's
a
working
dock
there.
It
is
okay,
he's
gonna
start
with
that
face
blade,
that's
porn,
seven
up
to
eight
inches
and
that's
all
we
know.
Sorry,
let's
say
anyone
else:
oh
no
hold
on
a
second!
So
there's
one
more
step:
you
can
do:
okay,
okay,
it
says
it's
a
5.4
cubic
inch
white
part
number
hydraulic
motor
in
the
part
description.
Take
that
google
it
and
see
if
you
can
pick
out
a
technical
internet
Hey.
C
Because
I
can
tell
you
on
the
tractor,
for
example,
the
micro
tract
that
we
build
once
again.
The
CAD
was
a
guess.
We
guess
how
the
motor
would
look
and
we
ended
up
having
to
do
major
reconstructive
surgery.
You
had
to
actually
cut
up
the
frame
because
the
motor
wouldn't
fit
and
we
had
to
redo
so
that
kind
of
stuff
is
we're
in
an
open-source
world.
C
C
C
C
C
C
D
D
So
there's
a
lot
of
parts
and
subparts
there
I,
you
said:
you're
gonna,
take
the
frame
I'm,
just
that's
gonna
determine
a
lot
of
the
shape
and
it
sounds
like
you
and
his
slats
full
of
it.
I
guess:
there's
different,
maybe
parts
the
frame
I
think
before
on
some
of
the
other
tractor
cabs,
and
things
like
that,
we
talked
about
using
some
lighter
steel
tubing.
Is
there
anything
like
that?
Cost-Effective
you
think
for
for
this
or
you
you
want
to
go
at
all
like
slats
and
no.
C
H
C
D
H
D
D
C
3D
print
it
sure,
okay,
Park,
you
genealogy.
A
B
A
C
C
E
C
F
Yeah
I
can
do
that.
I
am
while
I
was
looking
there.
I
see
that
they
also
offer
hydraulic
brakes.
Is
that
something
that
we
need
separately
or
does
the
hydraulic.
B
C
C
C
C
C
If
you're
asking
about
the
work,
dr.
work,
doc
is
organized
well
by
pages,
so
you
can
put
a
title
on
each
page
like
it's
good,
because
any
piece
of
the
puzzle
here
can
use
a
lot
of
supporting
information.
So
one
page
for,
like
even
one
page
for
part,
is
eventually
good.
Cuz,
you
yeah,
okay!
So
now
the
open-source
golf
cart
page,
it's
got
an
index
on
it,
click
on
free,
which
is
the
part
library
and
that's
where
the
things
go
into.
C
H
D
C
D
C
C
C
A
C
A
A
A
A
C
C
A
A
C
Continuing
okay,
so
we
have
the
PV
panel.
So
that's
Catarina
got
the
solar
panel.
C
G
C
D
E
C
C
C
A
C
Area,
okay,
so
we
missed
all
these
parts
and
in
our
overall
modular
breakdown.
So
any
can
you.
C
A
A
A
C
C
C
C
There
so
the
power
cube
library
has
the
engine
in
it.
That's
the
ripple
engine
out
by
deleting
things
and
train.
Oh,
that's,
really!
Good
thanks!
Sam,
that's!
Actually
that's
pretty
comprehensive
there.
This
is
amazing,
okay
and
in
a
few
years
when
we
have
like
parts
for
everything,
we're
will
literally
be
able
to
fly
on
this.
C
C
G
C
Yeah,
that's
that's
right.
C
C
C
Jen
can
I
get
you
to
the
tires
fine
ourselves
wheels
like
or
draw
them
up
like.
Basically
like
six,
the
entries
in
there
already
ate,
you
can
start
with
the
ones
on
the
ones
part
page,
six
I
think
the
one
pick
up,
nah,
that's
probably
too
big
pick
up.
It's
probably
feel
big
Jen.
Can
you
find
us
some
or
dross-
and
we
add
like
a
cylinder,
but
the
big
picture
has
put
that
into
the
part
library.
So
that's
a
placeholder
can't.
B
C
G
D
Kind
of
a
frame,
actually
something
such
as
metal
after
the
metal
frame,
maybe
it'd,
be
easy
to
use
like
plywood
and
then
put
some
kind
of
you
know
actual
pad.
What
kind
of
padding
I'm
gonna
stick
on
it
for
just
some
comfortability,
you
know,
plywood
plywood
might
make
it
easier
to
do
that
and
just
put
plywood
in
a
frame.
Is
that
sound
good
yeah.
B
E
I
E
A
B
C
A
F
F
C
F
C
F
Yeah
I
found
the
right
one.
It's
a
page,
ten
of
I
think
it
looks
the
same
as
the
link
that
you
put
on
the
present.
Eight
I
followed
that
the
manufacturer
they
have
a
manual
with
specs
for
all
of
their
motors
of
this
type,
yeah
and
I
found
the
right
series
so
I'm
pretty
confident
that
this
is
the
right
diagram.
B
C
Okay,
so
it's
217
we're
an
hour
into
it.
We're
gonna
go
till
3:00,
but
let
me
just
review
the
kind
of
the
workflow.
So
what
we've
done
so
far
has
broken
down
the
thing
on
page
three
into
as
many
modules
as
we
can
do,
and
we're
trying
to
translate
those
into
meaningful,
dimensional
CAD,
which
means
technical
drawings,
that
we
then
take
to
a
repo
repository
which
is
going
to
be
the
page
on
the
wiki
called
open-source
golf
cart,
which
has
the
art
library
in
it.
C
At
this
point,
I
see
three
pictures
of
the
power
cube
in
there
in
the
part
library,
but
the
goal
is
to
embed
a
picture
and
an
actual
CAD
file
to
substantiate
that
picture
that
the
part
library.
So
if
in
the
next
45
minutes,
maybe
you
can
do
like,
even
if
you
don't
finish
it
just
seed
it
so
maybe
upload
the
first
version
of
the
file
like,
for
example,
if
you're
working
on
a
motor
you
got
that
face
plate
that
you
just
drew
up
out.
C
C
Then,
wherever
you
are,
you
can
have
somebody
else
work
on
it,
an
idea
there
is
like.
Well,
how
do
you
know
you
don't
get
into
conflict?
Even
if
you
have
low
coordination
like
say
you
uploaded
a
CAD
and
you
say
well
what,
if
somebody
is
gonna
upload
it
and
there's
gonna,
be
an
edit
conflict
because
they
did
another
version.
So
what
you
do
for
that?
You
just
check
if
there's
an
upload
like
after
yours,
when
you
start
working
on
something
just
see.
C
If
somebody
did
something
yet
and
if
so
download
that
new
version,
if
not
you're,
assuming
that
okay,
yours
is
the
latest
version
and
you're
doing
the
latest
work.
So
that's
kind
of
a
rough
way
to
think
about
it.
But
the
idea
of
how
do
you
control
that
kind
of
process
with
many
many
people
it's
complicated?
They
have
this
checkout
system
and
professional
cat
packages.
B
B
B
B
B
B
B
C
C
C
To
keep
everybody
updated
on,
what's
going
on,
you
can
put
in
a
slide
for
your
thing.
What
you're
working
on
to
show
me?
It
results
like,
for
example,
look
at
this.
This
immediate
result
on
the
frame
that's
the
base
of
the
frame,
so
you
can
kind
of
keep
people
up
to
speed
where
you're
at
and
that
keeps
the
excitement.
C
C
G
So
this
guy
is
actually
looking.
Do
you
have
it
turned
off.
C
G
To
share
yours,
I
haven't
been
able
to
hear
how
to
do
that.
I'll
keep
breaking
it.
I
think
I
may
I'll
try
chromic
dead.
C
C
C
To
the
library-
and
it's
we've
got
a
three
sided
frame
right
now,
but
where
the
three
sides
me
do
there's
an
angle,
the
effective
angle.
So
that's
that's
how
it
looks.
I
try
to
upload
the
latest
image.
I
see
their
thing.
There's
a
bug
on
this.
Well
there
it
is.
If
you
go
to
the
history
of
the
GC
frame,
dot
PNG,
it
shows
the
latest
yeah
I
should
be
able
to
see
it
as
it
doesn't
consist
of
three
sites.
F
F
C
Good,
so
that's
open-source
golf
cart
page
on
the
wiki.
Just
as
it
says
you
can
see
it
in
the
recent
wiki
changes
Jenna,
so
Jen
fu
yeah
the
working
pages
on
recently
wiki
changes.
Okay,
so
that's
kind
of
review
or
at
so
gone
back
to
D
slide
number
four
got
some
progress,
so
cab
frame
is
one
half
done
actually
got
three
sides
of
six
and
my
product
demo
is
right
and
slide
number
three.
C
So
there
it
is.
I
went
from
a
single
side
to
two
sides
to
three
sides,
and
it's
actually
useful
to
that
there,
because
an
average
sucker
would
take
angle
and
try
to
weld
a
frame
out
of
that.
I
can
guarantee
you
that
this
method,
what
I'm
showing
here
is
self
aligning
and
it'll
be
much
easier
than
starting
from
angle,
and
that's
by
learning
to
do
that
with
all
the
frames.
E
C
We've
done,
but
I've
got
three
frames
out
of
six
and
it's
useful
to
kind
of
see
the
screenshots
cuz.
You
see
how
the
process
goes,
one
by
one
step
by
step,
so
now
I'm,
just
gonna
copy
those
parts
to
the
other
sides
and
that's
a
full
frame
and
that's
up
on
a
wiki
at
the
part
library.
So
if
you
go
to
the
part
library
on
the
wiki
that
is
already
there
soon
know,
anybody
can
take
that
and
take
it
from
there.
So
now
we
made
it
accessible
globally.
F
Trouble-
and
you
just
think
has
won
six
on
my
Mac
since
I
have
available
yeah,
so
we're
close
a
little
bit
different
I
have
a
10
dimensional
the
schematic.
Well,
so
I
have
a
schematic
that
I
found
and
I
have
it
as
a
layer
and
I
can
edit
that
model
there.
But
it's
being
really
stupid,
like
a
my
image,
is
blocking
anything
that
I
create.
E
C

Put
the
pieces
of
plywood
with
if
you
want
a
comfortable,
you
know
seat
with
some
foam
on
a
the
easy
way
to
put
foam
or
whatever
on
is
on
wood
right.
So
you
just
you
know,
there's
different
ways
to
do
upholstery
for
seats
yeah
if
that's
usually
done
on
a
piece
of
wood
and
that
gets
bolted
to
your
frame.

Actual
picture
that
was
pasted
it
into
the
freecad,
but
if
it
were
to
scale
then
then
reverse
engineering.
Now
that
would
be
BAM.
You
reverse
engineer
it
right
off
technical
drawings
that
you
find
online,
which
is
very
useful.
So
here
I'm
gonna
go
to
close
that
sketch,
selecting
that
sketch
extrude
it
out
and.
C
Yeah
cool,
oh
sure,
you
did
look
at
that.
We
just
extruded
something
a
little
bit
of
reverse
engineering,
101
right
here
now,
let's
see
like,
if
I
do
the
measurement
like
what
what
is
the
actual
scale
I'm
at
here,
so
I'm
measuring
that
and
it's
showing
me
three
point:
five,
eight
inches,
that's
close
because
that
that
should
be
four
point:
eight
five!
So,
let's
see
can
we
that's
an
instruction
can
be
scaled
as.

To
wrap
up
well
we'll
continue
working
on
this
as
far
as
the
individual
cat
files
and
keep
uploading
things
to
the
wiki
and
report
on
this
on
a
social
media
and
I
guess
for
the
people
on
the
dev
team.
So
we'll
see
you
on
Tuesday
again
and
Kati
and
others
thank
you
for
participating.
Many
questions
are
like
who
can
you
Katie,
maybe
fault
of
doing
that,
workflow
that
we
discussed
just
some
time
to
do
that.
F
F
C
Let's
see
as
far
as
I'd
say,
let's
continue
working
on
this
for,
like
a
couple
of
weeks,
I
would
say:
let's,
let's
hold
another
small
design-
sprint
like
this
in
a
couple
of
weeks
to
see
where
we
are.
If
we
pulled
it
all
the
files
and
hopefully
we
get
towards
the
finished
design
in
like
a
couple
of
weeks.
