Okay,
yeah
I'll
do
that
I'll
I'll,
put
them
on
the
OSC,
download
them
and
put
them
in
so
a
1-1
good
news
here,
if
you've
heard
through
the
grapevine
finally
there's
one
gig
internet
in
the
area
and
we're
getting
that
must
all
currently
there's
gonna
be
online
about
30
days
or
so
so
we're
gonna
actually
have
real
bandwidth
coming
up
pretty
soon.
So
that's
gonna
be
good.
E
E
B
I've
got
some
notes
on
that,
but
we
don't
need
to
start
with
that,
and
most
of
the
last
meeting
was
talking
about
ways
to
break
down
the
different
projects
into
effective
things
for
the
hackathon
and
then
Chaz
who
I
want
to
say
is
in
Minnesota,
but
it
might
be
Michigan
a
was
listening
in.
He
used
to
be
a
builder
I
think
with
OSE,
and
he
was
he
he
was.
B
He
joined
the
meeting
and
then
he
talked
about
his
press,
I
wanna,
say
CV
seam
press
something
talked
about
his
projects
and
then
we
got
into
a
big
conversation
about
scale
models
and
how
scale
models
would
be
an
interesting
project
like
for
coding,
for
you
know
for
scaling
them
down.
They
get
good
for
toys.
They'd
be
good
for
demonstrating
they'd,
be
good
for
practicing
building
a
lot
of
the
benefits
of
scale
models
and
yeah.
D
E
B
E
G
I'm
here
attending
I
haven't
been
deep
into
anything
lately,
but
I
am
going
to
be
presenting
in
a
few
months.
The
3d
printer
here
at
MSU,
so
I
need
to
get
that
up.
Oh
nice.
E
Nice
and
then
it's
talking
about
3d
printer
you've
got
you
still
have
the
on
your
printer.
You've
got
when
you
work
here:
the
proofs
I
three
m'kay
m'kay
extruder,
which
we
could
not
get
that
thing
to
work
without
with
retraction
I.
Don't
know
if
you've
followed
that
conversation,
so
it
works
really
well
when,
when
we
disable
retraction
in
it,
so
you
get
a
little
bit
of
kind
of
like
these.
E
These
stringing,
artifacts
it
works.
I
would
actually
suggest
upgrading
to
the
latest
greatest
I
mean
you've
got
100
bucks
for
an
authentic
III,
D
extruder,
which
is
what
we
use
in
a
current
version.
The
e3d
titan
arrow
extruder,
which
for
us
our
sake,
is
positive
in
a
sense
of
it
works
very
well
with
flexible
filaments
as
well
as
normal
filaments.
That's
the
preferred
choice
and
we're
really
going
with
that.
E
In
fact,
for
the
Titan
Aero,
the
omnidirectional
fan
shroud,
guess
what
I
did
I
just
downloaded
design
from
lulzbot
from
the
lulzbot
mini
to
printer
in
freecad
native
freaked
out,
because
those
guys
are
real
and
they
use
free
CAD
for
their
designs.
So
if
you
go
to
on
the
wiki
to
the
see
3d
printer
shooter.
E
E
You
guys
want
to
take
a
look
at
that,
so
the
3d
printer
extruder
page
on
the
on
the
wiki
and
the
index
go
to
part
library
under
strong
underslung
extruder
full
files
there.
So
you
see
the
titan
arrow
and
the
fan
shroud.
Look
at
that
crazy
thing.
So
I
took
that
from
lowe's
bot
and
modified
it
to
mount
it
on
existing
in
a
same
universal
access
system
that
we
have.
So
it's
pretty
nice
and
tight
and
the
picture
there
that
you
see
in
the
first
in
the
in
a
gallery
there.
E
That's
what
the
actual
thing
looks
like.
So
it
looks
pretty
tight.
It's
got
the
fan
shroud
with
a
fan
blowing.
It's
got
the
large
sensor
there
and
the
titan
arrow
as
the
cornerstone
of
that
and
now
the
carriage
because
of
the
flexibility
of
the
universal
axis,
the
carriage
could
be
vertically
oriented
or
it
can
be
horizontally
oriented
because
the
bolt
mounting
holes
on
the
carriages
can
you
can
attach
things
both
way.
So
it's
got
that
4
bolt
pattern,
but
anyway,
the
actual
picture
of
what
that
looks
like
would
clearly
be
under
D
3
D
genealogy.
E
So
if
you
look
at
I
know,
it's
called
D
3
D,
the
18
point
12,
because
I
did
this
in
December.
Here.
If
you
go
to
the
D
3
D,
the
1812
page
on
the
wick,
you
can
see
actual
pictures
of
the
Machine
of
the
extruder
as
built,
and
if
you
go
to
the
workshops
page,
you
probably
see
some
pictures
of
the
actual
printer
with
a
thing
mounted.
E
So
you
can
take
a
look
at
that,
but
that's
kind
of
like
the
latest
thing
and
you
see
the
same
carriage
and
then
the
whole
extruder
assembly
mounts
on
a
carriage
and
now
using
the
standard
triangular
like
that,
it's
called
the
mount
bracket
using
that
right
now
so
using
the
stock
mounting
bracket
that
attach
is
gonna
clamps
around
our
carriage.
So
you
can
see
the
take
a
look
at
the
Freak
app
file.
You
can
unravel
that
whole
assembly.
E
So
now,
if
flows
about
minis
got
some
of
the
highest,
if
you
look
at
the
ratings
of
loads,
about
Mini
2
and
make
magazine
last
year
was
like
third
place
or
so
or
very
much
near
the
top
of
ratings
of
like
20
top
3d
printers.
So
the
print
quality
is
really
high,
using
this
style
of
extruder.
Okay.
So
that's
the
update
on
a
3d
printer
right
now,
there's
a
workshop
happening.
So
there's
a
Kansas
Highland
Community
College
in
Kansas,
so
that's
happening
on
February.
E
Just
today
received
some
communications
from
people
in
New
Orleans
or
might
be
running
workshops
soon
after
in
New,
Orleans
and
there's
some
other
stuff
happening
in
Europe
in
terms
of
some
teachers,
potentially
teacher
training
they'll
be
in
and
then
their
Netherlands.
If
that
goes
through
and
the
guys
from
Canada
there's,
there's
Russ
Purvis
who's
working
on
on
build
getting
the
basically
sourcing
the
materials
in
Canada
right
now,
so
I
can
do
a
build
up
there
for
about
12
printer
builds
in
Canada.
E
So
there's
there's
a
bunch
of
stuff
going
on
and
trying
to
really
develop
that
to
the
final
completion,
I
mean
it's
kind
of
been
slow
over
the
Christmas,
and
now
that
I
must
update
on
a
brick
press.
Let's
go
into
that
because
that's
kind
of
take
it
took
me
a
little
bit
off
track
on
the
brick
press
and
sensed
in
a
sense,
that's
so
Scott
made
or
who
bought
the
vert,
the
the
brick
press
a
couple
of
years
ago.
He
never
picked
it
up
here
since
we
used
it
for
the
CD
go
home
build.
E
So
it's
actually
still
here
and
I'm.
Adding
a
new
controller
on
that
and
I
want
to
just
talk
a
little
bit
about
that.
So
look
at
numbers
slide
number
seven.
So
this
is
what
we
have
right
now,
that's
the
brick
press
actually
without
the
hopper.
That's
when
we
were
using
it
to
make
some
bricks
for
the
CD
go
home,
some
of
the
floor
bricks
and
some
thermal
wall
bricks,
but
yeah
we'd
be
getting
seven
books
per
minute
there.
E
So,
historically
speaking,
we
used
the
controller
that
used
MOSFETs,
so
basically
get
your
Arduino
brain
activating
mas,
activating
MOSFETs
to
run
some
hydraulic
solenoids.
The
things
that
switch
to
hydraulic
power
on
and
off
the
hydraulic
fluid.
So
right
now
we're
simplifying
that
greatly
before
use
the
custom
board
and
now
I,
don't
know
what
happened
a
long
time
ago,
when
maybe
that
cut
that
relay
Shield
for
Arduino
did
not
exist,
but
we
went
with
a
custom
board
before
and
it's
like
man
that
was
so
much
harder.
So
right
now
we're
using
an
Arduino
a
custom.
E
A
simple
custom
board,
simple
non
custom
board,
a
simple
shield
that
mounts
right
on
top
of
the
Arduino
on
page
eight,
so
that
mounts
on
top
of
the
Arduino
and
that
switches,
the
the
solenoid
solenoids,
the
hydraulic
solenoids,
which
are
you're
2,000
or
3,000
psi
hydraulic
pressure,
switching
solenoids,
as
you
see
on
page
9
there.
So
that's
the
actual
breakdown
of
the
hydraulic
valve
detail
more
details
about
the
switch,
but
man.
The
system
is
very
simple
like
if
you
look
at
page
8
you've
got
the
Arduino.
You
connect
that
to
power.
E
You
connect
the
shield
on
top
of
the
Arduino
through
the
headers
directly,
and
then
you
just
plug
in
one
plug
that
holds
the
selector
switch
DuPont
connectors
so
that
the
headers
there
on
the
on
top
of
the
the
shield
you've
got
a
pressure
sensor
and
a
selector
switch
through
this
10
pin
header.
So
just
basically
one
plug
into
that
very
little
custom,
wiring,
no
custom
board
all
off-the-shelf
materials.
E
E
It's
a
high-pressure
2000
to
3
like
1500
to
3000
psi
pressure
switch
for
the
brick
press,
so
that's
what's
going
on
there
and
what
I'll
probably
do
is
end
up
printing,
a
nice
and
closure
for
that.
Where
this
mounts
simply
in
a
small
enclosure,
that's
3d
printed
and
then
a
band
I
were
talking
about
Abe's
looking
into
little
LCD
displays
that
can
plug
into
this
Arduino
so
that
we
can
have
a
brick
counter
display.
So
we
want
to
get
the
longevity
of
the
Machine
data
like.
E
Let's
see
see
how
many
bricks
we
press
thousands
of
bricks.
So
that's
good!
Now
this
brick
press
is
going
right
now
to
Florida,
actually
cuz,
that's
where
Scott
is
living
right
now
and
we've
considered
actually
doing
a
I
mean
we
were
looking.
We
are
looking
into
a
build
in
Florida,
but
we
know
that
of
a
Seabee
house,
a
small
demo
house
and
now
Katrina
is
actually
back
in
business.
She's,
designing
a
brick
small
version
of
the
CD
go
home
with
brick
Seabees
we're
looking
at
the
possibility
of
Florida.
E
The
Florida
doesn't
work
out
because
they're
some
of
the
strictest
hurricane
codes
there,
which
means
that
would
add,
significant
cause
to
the
to
the
build,
but
we
are
considering
either
Florida
or
Belize,
so
Belize
might
be
in
November.
Now
we're
still
looking
at
October
for
the
Utah
build
another
guy
there.
Who
has
our
brick
press
also
a
friend
of
Scott's,
so
Scott's
gonna
been
seminal
in
this
funding.
The
brick
press
work
here
because
he's
he's
bought
two
of
these
machines.
E
One
is
in
Utah,
and
this
one
is
the
factory
farm
here,
but
that's
the
kind
of
the
schedule
we're
looking
at
a
build
late
in
a
year,
so
we
can
get
back
to
the
the
house
builds.
So
that's
where
we
are
on
the
brick
press
and
that's
the
3d
printer
update.
One
thing
I
did
want
to
talk
about
scale
models,
because
if
we
talk
about
OSC
clubs,
so
we
do
have
our
London
International
Academy,
there's
William
there
who's,
currently
working
on
an
on
a
cordless
drill.
E
Now
what
he's
doing
is
quite
interesting,
he's
gonna,
open
source,
the
there's
that
opens
not
open
source
3d
printed,
electric
motor,
the
600
watt,
one,
if
you
guys,
haven't
seen
that
Google
3d
printed
electric
motor
he's
gonna
open
source
that
for
the
cordless
drill,
so
that's
actually
really
cool
that
it's
gonna
be
3d
printed
with
magnets.
It's
got
many
uses
magnetic
PLA
for
the
core
around
which
the
magnets
go.
So
it's.
If
we
can
open
source
a
nice
decent
performance,
3d
printed,
electric
motor,
that
would
be
a
great
contribution
now.
E
William
is
working
on
that
for
the
cordless
drill.
That's
great
stuff.
Let's
talk
about
scale
models
for
any
of
the
machines
like
this
occurred
to
me
for
the
brick
press
right
now,
because
why
not
print?
First
of
all,
you
can
print,
of
course,
is
the
thing
in
miniature
and
you
can
print
it
in
the
sections
just
like
we
cut
it
out
of
steel.
E
So
say:
that'll
be
a
great
student
project.
You
know
with
OSC
clubs
or
something
where
we
can
3d
print
the
individual
parts
and
then
just
glue
them
together,
they're
kind
of
notched.
So
you
know
how
you
know
how
but
glue
them
together
and-
and
you
can
document
at
scale
at
a
scale
model,
how
the
thing
goes
together.
Now,
what
about
adding
the
controller
and
active
elements
like
the
hydraulics?
E
Well,
why
not
take
a
small
50
psi
hydraulic,
not
hydraulic
water,
water
pump
like
a
small
diaphragm
water
pump,
12
volt
use
that
to
pump
water
and
3d
print
your
cylinders.
So
you
can
see
some
online.
You
can
find
3d
printed
hot
water
cylinders
and
there
you
could
have
the
actual
motion
elements
of
the
brick
press
using
a
small
water
pump
so
hydraulics.
While
we
run
them
at
three
thousand
or
two
thousand
psi
for
the
real
machine.
So
you
can
run
it
at
small
pressure
like
50
psi
and
run
small
components
that
run
with
water.
E
So
it'll
be
safe
for
kids
to
play
with
that
or
if
safe
for
prototyping
during
hackathons.
So
that
would
be
excellent.
Now
you
can
do
that
for
the
brick
press
for
any
of
the
hydraulic
machines,
so
like
prototyping,
the
tractor
or
anything
else
that
could
be
a
whole
realm
of
activity
that
can
happen
along
with
the
real
machine
development.
So
so
there
could
be
a
whole
function
of
people.
E
Whole
whole
team
of
people
working
on
the
scale
models
which
would
be
an
exciting
contribution
that
eventually
does
contribute
to
the
real
builds
and
the
people
who
build
the
scale
models
would
be
qualified
to
actually
go
the
next
step
and
do
the
full-scale
machines
now
the
advantage
of
the
scale
models
is.
You
can
also
do
the
electronics.
Like
the
whole
controller
scheme.
You
can
test
that
out
on
a
scale
model.
You
can
have
the
small
washer
solenoids
that
could
activate
the
water.
You
can
have
a
small
pressure
sensor.
E
Those
are
all
inexpensive,
off-the-shelf
components,
so,
there's
point
being
there's
a
lot
that
can
be
done
with
the
scale
models,
so
I
would
encourage
discussion
and
maybe
open
that
up
to
discussion.
What
are
the
thoughts
on
that
like
Jan?
Is
there
a
way
to
do
that
now?
Jenna
I
wanted
to
find
out
more.
The
hackathon
that
you're
talking
about
is
that
something
that
you
plugged
into
that's
already
exists
there,
or
is
this
something
that
you
created
I
plugged.
B
E
B
Have
a
good
packable
bite-sized
chunk
for
the
next
one,
so
I
can
get
people
working
on
a
team
they
even
bring
in
they
don't
call
them
scrum,
Lords
I,
don't
know
facilitators
to
help
keep
the
team
on
track
because
they
don't
expect
all
the
project
leaders
to
be.
You
know
facile
with
that,
but
I
need
to
project
something
something
finite.
Yeah.
E
B
Sign
up
for
all
these
free
classes
and
that's
how
I
found
the
hackathon
to
like
you
know,
there's
always
like
the
coat
there's
like
four
or
five
coding
dojos
in
Seattle
and
I.
One
of
them
got
back
to
me
to
find
out
if
I
was
interested
in
taking
courses
and
I
talked
about
like
the
stuff
I'm
working
on
and
that
it
didn't
seem
like
there
were
any
courses
that
were
really
applicable
to
what
I
need
it's.
Nobody
does
any
blockchain
stuff
and
that's
what
really?
What
I
want
to
learn
about.
B
But
I
pointed
out
that
if
they're
graduates
needed
something
that
they
could
work
on,
so
that
they
could
commit
gifts
and
such
like
and
stay
active
in
the
community
until
they
get
hired
that
they
should
consider
our
project-
and
she
actually
got
pretty
excited
about
that.
So
that
would
be
a
good
way
to
get.
People
on
the
team
would
be
to
interface
with
various
coding,
schools,
ya,.
E
B
B
D
B
Do
we
need
people
for
this?
You
know
what
do
we
need
people
for
absolutely
and
it's
okay,
and
so
two
things
that
employers
are
looking
for
here
are
actually
there
looking
for
committed
gifts,
which
you
know
that
goes
to
our
need
for
people
to
document,
they
need
commit.
They're.
Looking
for
committed,
gets
and
they're
looking
for
open
source
work.
They're,
like
did
this
person
volunteer
on
any
projects?
Are
they
really
actually
interested
in
what
they're
doing
these
are
perfect?
B
E
No,
that's
great,
so
I
would
say
like
the
brick
press,
it
is
a
low-hanging
fruit,
because
out
of
this
could
also
come
out
an
education
kit.
So
we
create
this
and
it
serves
both
to
teach
people
during
the
build
of
it
about
coding,
like
once,
they
get
to
the
actual
components
and
3d
printing,
and
then
we
could
end
up
packaging
that
as
a
kit
for
education
and
like
death
kit,
you
know,
like
okay
say
you
want
to
develop
new
functions
for
the
CB
press
right.
B
E
That's
the
that's
the
thing
like:
if
somebody
had
you
know
model
like
I,
wouldn't
have
to
do
that
right
here,
like
we
could
outsource
or
work
as
a
team.
So
then
somebody
actually
tests
and
verify
the
code.
Then
then
I
can
go
into
my
real
brick
press
right
now,
download
it.
It
would
probably
work
you
know,
so
you.
E
And
that's
that's
kind
of
the
way
I'm
thinking
like
if
you
get
the
fast
internet
here,
I
was
thinking
along
the
lines
of
preparing,
so
so
by
the
way,
I
am
definitely
spending
time
on
a
book
and
writing
writing
some
of
the
getting
my
head
around
writing
the
book.
Cuz
I
do
believe
writing
the
book
on
open
source
ecology
after
a
decade
of
work
here
is
important
to
align
the
community
and
get
a
clear
direction
now.
E
Part
of
that
I
was
thinking,
develop
a
course
like
a
online
course
where
we,
we
train
people
for
various
development
work
where
the
prototyping
and
the
skill
models
could
be
a
part
of
that.
So
imagine
getting
a
whole
bunch
of
OC
clubs
started
out
of
that.
We're
kind
of
give
them
get
the
ball
going.
So
yes,
definitely
huge
potential
for
school
schools
and
that
could
plug
into
the
real
prototyping
program
as
well,
so
definitely
worth
worth
trying
for
the
brick
press.
E
What
I
would
just
so
we
do
have
all
the
files
like
as
far
as
what
we
built
from
the
last
build
was
2017.
That
was
a
machine
that
went
off
to
Utah
actually,
but
that
was
2017.
You
can
look
at
the
CB
press
genealogy
on
a
wiki.
You
can
download
the
latest
the
Excel
files,
which
are
the
two-dimensional
cutting
files,
and
you
can
pretty
much
from
that.
If
you
you
can
download
the
files
and
just
print
them
out,
extrude
them
print
them
out.
E
So,
first
of
all
from
the
2d,
you
have
to
extrude
them
to
the
third
dimension
which,
because
they
have
a
finite
dimension,
like
there's
half-inch
steel,
so
say
when
you
these,
you
scale
that
down
say
a
factor
of
four
that
means,
instead
of
a
half-inch
the
piece
of
metal,
the
little
skill
model
thing
would
be
like
saying.
The
eighth
inch
and
a
quarter
scale
model
is
something
that's
realistically
doable.
E
E
So
if
you
do
a
one-sixth
scale
model,
that
means
the
largest
member
is
now
one
foot
long
that
could
fit
on
a
print
bed
like
say
our
one
foot
be
3d
or
some
other
printer
that
can
print
one
foot,
so
that'll
be
usable
right
now,
it's
the
it's
process
would
be
to
download
the
files
print
them
out
start
building
it
together
and
now
the
thing
that
we
have
to
figure
out
is
okay.
How
exactly
do
you
do
the
cylinders?
E
So
you
have
to
pretty
much
open
source
that
there's
there's
some
models
on
Thingiverse,
but
we
have
to
pretty
much
design
one,
that's
our
particular
size,
3d
printed
and
the
way
it
typically
works
is
you'd.
Have
the
in
order
for
a
water
not
to
leak
in
there.
You
have
rubber
o-rings
around
the
piston.
So
once
you
get
to
the
cylinder
part
to
look
at
the
details
of
how
a
cylinder
is
made,
it's
essentially
a
piston
like
a
like
a
needle
plunger.
E
You
know
like
a
hypodermic
needle
kind
of
deal,
it's
a
plunger
that
press
it
up
and
down.
There's
fluid
that
just
gets
pushed
in
and
out.
Essentially,
all
it
is
now
what
you
want
to
do.
If
you
use
3d
printing
is
you
can
either
print
the
o-ring
or
you
could
get
it
off
the
shelf
and
for
the
smooth
surfaces
it
will
be
easy
to
use
PVC
pipe
like
say,
one
inch,
PVC
pipe
to
provide
a
smooth
surface
for
the
cylinder
to
to
actually
work.
E
You
can
also
3d
print
it,
but
you
have
to
have
really
fine
resolution,
so
it
be
a
long
longer
print
a
while.
There
is
an
easy
option
of
taking
PVC
pipe,
which
is
a
few
cents,
for
you
know
a
few
inches
for
a
cylinder
so
that
wouldn't
be
a
big
cost.
So
it's
so
combining
like
off-the-shelf
PVC
with
3d
printed
cylinder
ends
and
things
like
that,
etc.
E
So
I
would
say:
Jenn
I
mean
going
go
ahead
and
propose
that
they
can
see
all
the
files,
and
you
can
do
that,
they'll
be
awesome,
so
and
and
what?
When
is
the
next
time
that
you're
meeting
with
the
people,
the.
D
B
Hoping
to
get
some
like,
they
provide
the
paper.
You
know
that
for
everybody
to
write
their
projects
on,
but
I
would
like
to
have
since
it's
an
ongoing
thing
and
I'm
sure
there'll
be
other
opportunities
to
present
for
open
source
ecology.
I
would
like
to
actually
invest
in
some
sort
of
classy
assets.
To
hang
for
us,
when
we
do
these
things,
yeah.
G
B
Have
something
that
look
you
know
it
I
cannot
tell
you
how
much
our
professional
website
and
wiki
helps
and
just
the
fact
that
we
have
TED
Talks,
because
people
are
kind
of
like.
Oh,
that's
like
this.
Oh
that's
like
that
and
I
just
say:
hey.
We
have
TED
Talks
and
you
know
I'm
being
plural
right
and
they're
like
oh
I,
like
TED,
Talks
and
then
I.
You
know,
stick
them
on
the
ose
TED
talk
and
handing
back
their
phone
yeah.
E
Yeah,
that's
cool
all
right
yeah!
Well,
that's
pretty
cool
excellent!
So
let's
keep
moving
on
here.
So,
let's
see
who
else
who's
next?
Who
wants
to
report.
E
E
H
I
hadn't,
let's
see
I,
keep
meaning
to
get
back
to
Mort
cat
at
least
I.
Keep
saying
that
because
I
do
think
that
there's
lots
of
cab
that's
important
to
do
and
it's
hard
to
find
people
to
work
on
CAD,
so
kind
of
been
one
of
the
few
people
doing
that
I
haven't
worked
on
the
PVC
printer
stuff
in
a
while
I
think
that
the
C
as
I
recall,
the
the
clamp
I
think
was
pretty
good.
H
The
design
there
and
I
was
trying
to
finish
the
assemble
sub
assemblies
and
assembly
of
the
whole
printer,
which
was
it
was
a
little
difficult
just
fitting.
All
those
sub
similes
together
see
that's
that's
an
older
photo
you're
looking
at
there,
but
yeah
I
think
it
was
a
was
delayed
up
with
a
two
piece.
Clamp
I
think
I
think
is
what
we
showed
before
right.
It
was
yeah,
I,
think
snow,
it's
two
bolts,
so
yeah,
that's
one
of
those
things.
I
need
to
get
back
with
and
I
was
I.
H
Think
John
I
think
suggests
the
different
points.
I
think
he
was
in
one
of
the
last
meetings,
or
at
least
there
was
I,
think
messages
or
something
I
saw
on
his
log.
He
was
hoping
to
get
back
to
working
on
his
PVC
3d
printer
I
think
it's
pretty
close
I
think
he
suggested
to
being
put
together
so
so
I'm
gonna.
E
E
B
E
H
Started
that
project
kind
of
a
few
years
ago,
hoping
to
utilize
it
just
to
kind
of
check
temperatures
with
some
cheap
sensors
and
so
on,
and
you
know
just
a
box
of
different
electronics
or
do
we
know
stuff
from
from
Adafruit
or
something
and
I
think
I
finally
solved
some
bugs
on
it.
I'd
kind
of
mostly
been
working
on
it
in
the
winter
occasionally
and
so
I
get
kind
of
lost
on
that.
H
But
if
I
think
I've
said
some
of
the
major
issues
recently
so,
but
but
I'm
also
thinking
I
need
to
change
to
different
hardware,
because
when
I
started
it
I
didn't
have
Wi-Fi
or
wireless
or
internet
really
here
so
and
now
now
I
think
wireless
would
be
helpful,
so
I
may
eventually
get
around
to
getting
a
wireless.
Almost
all
those
requires
a
more
advanced
board.
H
A
different
microcontroller,
probably
I,
think
the
what
is
it
the
mkr1000
I
think
was
a
good
one
with
Wi-Fi
but
they're
they're
different,
they're,
more
advanced,
so
there's
different
considerations,
but
and
that's
kind
of
why,
with
the
information
Ginn
was
talking
about
the
hackathon
on
what
I
think
it
is
could
use.
You
know
maybe
like
a
there's,
a
lot
of
libraries
that
are
open
out
there.
Some
of
these
LCDs
and
things
are
looking
at
four
different
projects:
I'm,
not
sure
that
the
boards
are
open
and
then
I'm.
H
You
know
some
of
the
software
is
just
totally
unlicensed
for
some
of
those
LCDs,
but
then
I
looked
and
I
found
open
source,
libraries
or
licenses
that
looked.
You
know
acceptable
for
some
of
those
things,
so
they
exist
if
you
hunt
around
but
connecting
all
of
those
different
libraries
together
for
some
of
these
more
complex,
you
know
microcontroller
projects,
it's
likely
could
probably
use
some
people
to
code
and
at
least
organize
more
on
the
weaking.
H
Maybe
a
big
project
page
with
you
know
all
the
libraries
kind
of
like
a
parts
library
but
software
libraries
that
are
open
that
can
be
used.
I
notice
that
that
Marlin
I
think
it
it
kind
of
a
lot
of
software
to
simplify
things.
There's
a
bunch
of
different
versions
of
possible
boards,
like
with
that
that
RepRap
LCD
kit,
there's
multiple
possible
versions
of
chips
and
and
different
versions
of
that
board,
maybe
ice.
That's
what
I
think
I'm
seeing
in
the
software
there?
H
So
sometimes
you
know
they
just
make
the
software
so
that
it
can
identify
the
different
chips
and
work
with
multiple
boards.
But
that
has
complexity
and
there's
a
lot
of
different
projects.
I
notice,
I
think
you've
got
a.
You
met
a
wiki
page
recently
about
a
universal
microcontroller
sort
of
design
so
that
some
of
these
people,
hackers,
I
guess
with
the
hackathon
stuff,
could
could
maybe
work
on.
You
know
organizing
libraries
and
making
libraries
that
can
help
make
it
easier
to
work
with
kind
of
putting
the
libraries
together.
H
I
don't
know
if
you'd
call
that,
like
an
API
but
there's
almost
always
a
need
to
interface,
multiple
libraries
together,
even
if
they're
already
in
existence
and
open
source,
it
can
be
a
little
more
complicated
to
write
the
code
using
all
of
them
together.
So
there's
a
need
for
that
yeah,
so
I've
been
kind
of
in
software
mode
and
other
hardware
stuff
lately,
but
and
I
think
there's
a
lot
of
possibilities
for
free,
CAD
software
too.
Right
because
we
talked
about
workbenches
before
openscad
I
mean
we
really
need
people
to
do.
H
Cad
and
I
keep
mewling
meaning
to
learn
more
up
and
SCAD,
because
I
think
it's
useful
for
a
bunch
of
things.
So
software
people,
maybe
they're,
not
familiar
with
openscad,
but
maybe
there'll,
be
some
people
that
are
interested
in
learning
that
because
that
would
probably
be
more
helpful
but
yeah.
There's
lots
of
project
software.
H
I
was
trying
to
tell
what
the
status
of
risk
5
is
because
that's
a
big
open
thing
that
seems
to
be
getting
very
popular,
which
is
great
but
I'm,
not
sure
I,
understand
the
openness
of
like
sigh
5
I,
don't
think
there
arduino-compatible
board,
isn't
necessarily
all
that
open
and
it's
still
expensive,
but
it's
a
more
advanced
board.
So
it's
hard
to
compare
but
I
think
some
of
the
software
stuff
they
use
to
make.
The
hardware
is
somewhat
it
seems
to
have
open-source
license,
but
I'm
not
sure
that
the
board
is
open.
H
H
I
mean
there's
a
lot
of
things
that
could
be
done
for
create
freecad,
I,
think
to
make
it
work
better
because
doing
assemblies
and
sub
assemblies
I
think
is
the
hardest
thing
right
now,
I
mean
it's
pretty
easy
to
teach
people
to
do
parts
and
stuff
like
that,
but
a
lot
of
times
getting
you
know.
All
of
that
organized
together
is
the
harder
part
and
freecad.
H
H
E
Putting
my
mic
off
again,
people
hear
me
now:
yes,
okay,
yet
house
gladly
talking
to
myself,
but
there's
a
page
called
getting
involved
on
the
wiki
and
in
it
you
can
feel
free
to
jot
down
some
concrete
ideas
on
code
works,
so
that
so
you
know,
there's
different
realms
of
engagement
there,
but
yeah
for
coding.
If
we
could
write
down
some
explicit
things
now,
is
that
that
page
is
open
for
edits
so
a
but
feel
free
to
put
the
code.
E
I
think
the
coding
notes,
as
far
as
what's
what's
important
right
now,
like,
for
example,
getting
the
brick
counter
added
to
the
brick
press
controller,
that's
they'll
be
cool.
That
should
be
an
easy
thing.
Things
like
that,
okay,
next,
let's
keep
going
then
miles.
Can
you
tell
us
a
little
bit
more
I
was
looking
at
the
DC
DC
converter,
stuff
and
I
saw
this
also
this
instructable
and
about
to
boost
converter
converter.
C
C
I
think
it
in
the
the
example
that
you
posted
to
use
that
p-channel,
so
that
could
work,
but
the
p-channel
MOSFETs
seem
to
be
a
bit
slower
and
they
have
a
bit
more
resistance.
It
wouldn't
be
would
still
be
less
than
a
watt
uh-huh
energy
losses,
but
yeah.
If
he's
in
he
works
fine.
It
could
be
depending
on
how
much
how
much
you
want
to
change
the
voltage
by
because
you
could,
you
could
change
it
like.
E
The
faster
the
frequency,
the
the
smaller
inductor,
you
can
use
yeah
yeah.
Okay,
do
you
have
any
of
these
components
resourced?
Er?
That's!
Is
that,
like
your
next
step
or
I,.
C
E
D
C
Could
I'm
just
not
sure
how
much
the
input
resistance
of
the
we
know
is,
and
so
I
just
put
the
op-amp
in
there
to
be
a
buffer.
It's
only
27
so.
E
Okay,
uh-huh
and
that's
like
a
tiny,
that's
like
a
little
chip
like
a
thing
with
like
big
pins
or
something
or
yeah,
okay,
yeah.
That
could
be
cool.
So
what's
the
limit,
so
it's
it's
30
amp
max
current
or
like
the
voltage.
Okay,
the
voltage
rating
is
determined
by
what
which
components
fry
if
you
go
higher
so.
E
Volts
I
see,
aha,
are
those
MOSFETs
like,
let's
see
I
mean
if
we
wanted
to
do,
let's
see
30
a
clamp
smacks
current
say
you
got
12,
24
volts,
that's
that's
pretty
decent
for
now
and
talking
about
scalability
like
if
you
do,
is
it
just
replacing
those
those
two
things
or
is?
Would
it
be
a
lot
of
liquid
the
driver
be
the
same
or
the
driver
changes
to
I
I.
E
E
720
watts,
that's
good
what,
if
you
want
to
charge
more,
if
you
wanna
do
like
no,
you
just
need
more
power.
How
do
we
do
that?
I?
Guess
we
will
do
one
thing
at
one
step
at
a
time,
but
when
you,
when
you're
designing
this,
are
you
giving
thought
to
like
okay?
What
happens
when
I
just
use
the
fat,
some
batter
components,
I
mean?
Are
they
gonna
be
way
way
more
expensive
or
it
still
will
be
affordable?
E
C
E
Cool
yeah
yeah,
so
this
is
like
35
parts
per
pot,
35
bucks
for
parts
shown
here.
That's
awesome,
let's
see
what's
the
okay,
can
you
explain
to
me
like
this
hole
so.
E
F
E
E
E
Okay,
right
right,
you
have
that
documented
anywhere
else
like
about
the
system
system
design,
oh
yeah,
okay,.
F
E
Right,
well,
that's
cool!
What
should
what's
your
schedule
on
on
this
like?
When
would
you
think
you
could
actually
prototype
this
thing.
A
E
E
G
C
C
C
Well,
they
act
to
to
have
charge
storage
elements
so
when
the
switch
is
on
the
the
inductor
occurs,
the
current
flows
through
the
inductor,
and
so
the
inductor
wants
to
keep
whatever
current
is
flowing
in
it
flowing.
So
when
you
turn
the
switch
off,
if
the
current
little
one
want
to
keep
current
flowing
in
the
same
direction
to
it,
but
without
this
with
the
switch
open,
they
won't
be
able
to
go
back
for
the
input.
So
the
only
way
it
will
be
able
to
go
is
do
the
output
uh-huh.
C
E
That's
good
and
there's
in
this
circuit
design,
there's
not
really
a
limit
like
this
basic
design
pending.
Of
course,
some,
like
heat
dissipation,
I,
say
you
make
this
larger
I
was
asked
about
larger
here
like
this,
for
us,
like
the
real
interesting
stuff
gets
into
things
like
resentful
welder
right.
E
So
if
you
scale
the
the
capacitor,
the
inductor
and
and
the
transistor
or
make
a
bunch
of
those
transistor
happen
like
a
bank
of
them,
so
you
can
scale
those
transistors,
so
you
can
even
use
the
same
one
and
multiple
Wow
goodness
like
one
way
to
scale.
The
circuit
would
be
to
simply
use
multiples
of
the
same
components.
That's
work.
C
C
E
E
We're
kind
of
talking
about
a
basic
anyone,
who's
kind
of
like
what's
in
there.
It's
definitely
basic,
not
like
I,
have
a
clue
of
what's
going
on
in
there
altogether,
but
it's
not
to
not
to
conflict.
Okay,
thank
you
and
if
anybody
else
wants
to
get
involved
who's
watching
this
and
prototyping
this
and
make
this
a
scalable
system,
that's
that's,
then,
put
into
an
electrical
3d
printed
enclosure
made
into
the
real
product
join
the
team.
Ok
moving
on,
so
thank
you
miles.
Do
we
have
anyone
else
reporting
today?
Please.
E
That's
good:
your
salon
is
not
here.
B
Yeah
I
haven't
I
thought
I
had
a
spreadsheet
that
had
some
contact
information
for
the
different
things,
I'm
actually
kind
of
overwhelmed
with
that
I'm
underwhelmed
with
the
number
of
states
that
offer
money
and
I
still
haven't,
figured
out
how
to
get
into
the
into
the
different.
Like
funding
programs,
you
know
like
I,
guess:
I'd
need
to
just
start
contacting
people
I
think
we
need
to
put
together
something.
A
B
B
Oh
I
know
I
put
it
on
I
put
it
on
my
page,
so
let
me
see
behind
it,
so
the
because
some
some
of
the
things
that
they
pay
for,
like
they'll
pay
for
website
access.
So
if
we
could
have,
we
could
have
I,
don't
know
if
we
want
to
do
that,
but
we
could
have
like,
but
then
that's
not
open
source
and
they'll
pay
for
clubs
and
they'll
pay
for
ongoing.
You
know
for
like
ongoing
access
to
teaching.
B
G
B
B
This
is
the
link
to
the
idea
programs
homeschooling
page
when
at
their
page
it
talks
about
the
different
ways
that
allotment
can
be
used
and
how
much
allotment
there
is,
for
example,
there's
nineteen
hundred
year
for
grades
K
through
three
2100
for
grades,
four,
through
eight
and
twenty
four
hundreds
for
grades
nine
through
twelve
and
the
typical
homeschooling
family
has
three
kids.
A
typical
homeschooling
family
is
going
to
have
over
six
thousand
dollars
a
year
that
they
can
spend
on
allotment.
A
lot
of
that's
going
to
go
for
my
experience.
A
lot.
B
That's
gonna
go
at
a
hockey,
Space
Camp,
there's
a
really
good
space
camp
on
the
Kenai
Peninsula,
for
example.
Alaska's
got
a
lot
of
really
good,
interesting
things,
so
we'll
pay
they'll
pay
for
books,
general
homeschooling
supplies,
literature,
social
studies,
materials,
I,
really
think
that
oh
s,
he
can
integrate
unit
studies
and
like
homes
in
in
social
studies.
Because
because
we
are,
you
know,
economics
in
social
studies,
math
manipulatives
I
was
thinking
if
we
sold
like
3d
printer
packages,
that
included
the
programs
for
doing
like
different
kinds
of
math.
B
Manipulatives,
like
the
older
kids,
could
be
printing
up
stuff
for
the
little
kids
to
use
and
then
they're,
fully
recyclable,
or
you
can
make
your
math
manipulatives
out
of
your
recycled
water
bottles.
They'll
pay
for
software
internet
subscription
boxes,
I,
don't
know.
If
there's
any
way,
we
could
do
a
subscription
box
electronic
hardware,
they
do
pay
for
Hardware.
Now,
educational
toys
and
brain
games,
curriculum
packages
and
online
subscription
based
programs
are
all
things
that
I
think
that
we
could
take
advantage
of
somehow
ways
that
we
can
help
the
community
and
also
generate
some
funding.
B
That's
that's
what
the
ideal
homeschool
program
pays
for
and
I.
Don't
know
if
it's
better
I,
don't
know
if
it's
better
to
start
trying
to
break
in
or
like
one
really
dialed
in
homeschooling
program
like
that
or
really
dialed
in
state
like
Alaska
and
then
spread
from
there
like
get
some
legs
somewhere
and
then
spread
or
if
I
should
just
start
hitting
everybody
and
hitting
all
the
different
programs.
I
mean
it's
a
really
professional
gig.
It's
not
like
we're
trying
to
sell
something
that
doesn't
work.
Yeah.
B
E
B
E
E
B
E
C
E
Can
copy
it
still
too,
but
that's
that's
me.
Maybe
we
could
yeah,
like
maybe
some
education
materials
are
something
around
like
even
putting
together
a
curriculum.
Okay,
here's
you
know
say
they
have
a
3d
printer,
but
after
they
would
have
a
3d
printer
to
do
the
product
say
the
prototyping
of
the
scale
models
and
put
a
little
package
around
that
and
some
guidance
around
that
or
even
classes
around
that
for
people
who
would
find
it
compelling
I
mean
seriously.
D
B
Big
there
I
really
could
have
been,
because
you
know
my
kids
used
to
all
the
kids.
You
know
did
they
go
outside
and
they
build
things
yeah,
not
that
much
to
do
and
we
don't
homeschool.
So
our
kids
can
watch
TV
all
day.
You
know
you
boot
their
little
butts
outside
and
then
they
get
a
think
of
stuff
to
do.
