Description
Remote Labs and FPGA discussion for 31 January 2023
A
B
A
A
A
B
I,
don't
remember,
I,
don't
think
we
have.
We
don't
have
a
standing
meeting
on
Wednesday,
but
we
we
sometimes
meet
up
to
talk
about
stuff
on
various
days.
I
know
that
we
have
had
we've
had
Wednesday
meetings
in
the
past,
but
we
try
to
keep
them
on
Tuesdays,
at
least
for
the
for
the
phase
four
stuff.
B
We
do
try
yeah.
This
is
what
this
is,
is
a
sort
of
a
weekly
meeting
for
all
of
our
field,
programmable
Gatorade
work.
So
what
we're?
What
we
focus
on
is
fpga
stuff
and
what
we
do
for
the
meeting
is
talk
about
what
we've
done
over
the
past
week
and
then
what
we're
going
to
be
planning
to
do
over
the
next
week
and
then,
if
we
have
any
resources
that
we
need.
B
So
if
somebody
needs
something
to
get
get
things
done
or
if
there's
any
roadblocks
that
are
in
their
way,
so
something
that
they
don't
know
how
to
do
or
hit
a
wall
on,
and
then
we
can
call
in
help,
and
so
those
are
the
kind
of
the
four
things
that
we
try
to
do
every
week
in
in
a
lot
of
traditional
management
structures
that
use
agile.
This
is
done
every
day,
but
we
don't
do
that
so
for
for
a
volunteer
organization.
We
do
it
once
a
week
on
when
on
on
Tuesdays.
Well.
A
B
B
No,
that's
a
that's
a
good
point.
That's
something
that
we
we
come
up
against.
A
lot
is
that
there
is
there's
a
lot
of
good
tutorials
that'll,
get
you
up
and
running
with
your
fpga
board
or
that'll.
Get
you
to
the
point
where
you
can
do
some
sort
of
hello
world
and
then
there's
pretty
much
nothing.
You
kind
of
get
dropped
on
the
floor.
B
If
you're
trying
to
do
some
sort
of
adaptive
or
or
ambitious
project
and
I
think
what
we're
trying
to
do
with
the
multiplexing
transmitter
for
microwave
is
is,
is
complex.
There's
a
lot
of
stuff
that
just
that
hasn't
been
done
before
in
open
source
work.
Then
then
you're
you're
kind
of
like
well.
How
do
you?
How
exactly
do
you
do
it
and
there
may
not
be
any
good
examples
or
good
pedagogy
out
there?
B
So
there's
not
a
lot
in
the
middle
in
that
vast
center
part,
and
you
can
find
some
good
examples
of
some
some
very
complex
code
like
at
the
PHD
level,
but
these
are
snapshots.
So
you
know
it's
a
the
learning
curve
is
is
exceptionally
steep,
I
I
believe
for
for
any
sort
of
fpga
work
and
the
crossover
or
the
the
number
of
people
that
are
good
at
radio
and
that
have
a
a
working
knowledge
of
like
digital
Communications
and
RF,
and
the
people
that
also
know
how
to
write
HDL
code.
B
That
overlap
is
very
small
and
those
people
are
in
hot
demand,
so
getting
a
volunteer.
That
knows
both
is
deeply
appreciated
and
valued
for
us,
because
well,
we've
helped
a
lot
of
people
get
better
jobs
and
we've
put
a
lot
of
people
into
PHD
programs.
But
you
know
it's
a
constant
battle
to
try
to
to
staff
up
and
to
stay
staffed
in
a
in
a
we're
competing
with
with
lots
of
companies
that
would
really
like
to
pay
people
out
of
money.
So
we
we.
D
B
That,
as
like
part
of
our
educational
Mission,
we're
we're
helping
just
like
the
the
amateur
license,
says
that
you're
supposed
to
help
with
the
technical
core
in
the
U.S
and
I
can
tell
you.
We've
certainly
done
it.
You
know
this
is
just
an
area
where
there's
not
a
lot
of
people
and
a
huge
amount
of
demand.
So.
A
B
B
I
guess
my
goal
is
to
make
it
not
that
harsh
of
an
experience
to
make
it
a
little
bit
better
and
also
to
make
it
repeatable.
So
so
what
I?
What
we've
done
with
the
remote
Labs
is
to
try
to
make
it
to
where
okay,
here's
a
reference
design
from
a
from
a
company
and
it's
open
source,
so
Analog
Devices
reference
designed
for
the
xilinx
chipset,
and
then
here's
how
you
fit
in
your
code.
B
So
you
have
a
DSP
idea
or
something
that
you
really
want
to
do
and
we're
able
to
to
fit
it
in
to
an
existing
reference
design
that
operates
the
rest
of
the
radio
and
the
rest
of
the
fpga
and
the
general
purpose
processor
and
we're
getting
there.
It's
it's
really
hard.
This
is
not
easy
stuff
at
all,
but
enabling
people
to
focus
on
what
they
really
want
to
work
on
their
particular
part.
You
know
that's
the
goal,
so
that's
the
that's
part
of
what
we
do.
B
Probably
will
not
improve
in
the
short
term,
but
it'll
improve
one
day
and
we'll
we
all
need
to
be
ready
as
far
as
cheaper.
There
is
at
least
for
the
xilinx
side
of
the
house.
We
know
that
there's
a
inexpensive
part,
that's
been
introduced
and
announced
and
we're
looking
to
make
a
board
with
that
part.
B
So
Leonard,
the
guess,
is
the
lead
for
that
at
Ori.
So
that's
pretty
exciting
delivery,
though
like
actually
getting
the
parts.
As
you
know,
this
has
not
been
real
fun,
but
it
again,
you
know
you
just
I
think
we
all
will
will
just
have
to
keep
trying
and
be
vigilant-
and
this
is
the
sort
of
thing
where
eventually
one
day,
we'll
start
getting
better
and
we'll
get
better
pretty
quickly
and
I.
Don't
know
when
that
will
come
paying
attention
to
to
Industry
folks.
B
A
B
And
like
for,
for
those
of
us
doing
this
sort
of
prototype
or
or
low
volume,
work,
100
is
kind
of
a
lot.
You
know,
that's
that's
our
high
volume
in
a
lot
of
cases,
and
it's
just
not
it
just-
does
not
seem
to
be
enough
where
it
used
to
be
so,
it
will
get
better,
but
not
as
quickly
as
we
would
like.
I
think
we're
very
fortunate,
because
we
do
have
development
stations
for
ultrascale
plus
and
for
Ultra
scale
and
7000
series.
B
We
have
a
Pluto,
we
have
some
other
donated
gear,
we
get
an
sr1
Pro
so
and
we
have
some
dvbs2
and
S2X
gear,
so
we're
lucky
that
we
have
things
that
people
can
log
into.
But
remote
operation
is
hard.
You
know,
even
with
dedicated
people
supporting
it,
it's
still
much
less
of
a
sort
of
a
nice
experience.
It's
it's
it's
not
as
good
as
having
it
on
your
own
desk
or
being
able
to
order
some
of
these
development
stations
yourself.
So
we're
very
lucky
that
we
have
Hardware
that
we
can
make
progress
on.
B
D
B
Were
expecting
to
be
able
to
to
be
in
layout
and
to
produce
these
to
have
already
gone
through
the
process,
so
I
think
we
are
not
on
that
track.
We.
We
are
further
ahead
on
some
of
the
other
aspects,
like
the
software
design
and
htl
design
that
but
like
only
because
we
had
the
dev
boards
and
good
good
for
us,
but
like
I,
talked
to
other
companies
and
other
organizations,
and
it's
that's
no
fun.
So
that's
that's
the
way.
B
It
is
right
now
and
you
know
I
guess
we
just
watch
and
wait
and
there's
a
lot
of
inelastic
parts
to
the
supply
chain
that
they
it'll
work
out.
But
it's
like
it.
Those
inelastic
parts
are
the
bottleneck
and
and,
like
you
said,
if
we
were
able
to
order
a
Million,
Parts
I
think
we'd
get
what
we
want,
but
we're
not
gonna,
be
We're,
not
gonna,
be
ordering
a
Million
Parts.
So.
A
B
B
Varies
it's
these
are
stations
all
of
the
stations
in
remote
labs
are
intended
for
open
source
development.
Primarily
you
know
targeted
for
amateur
radio
bands
but
available
for
any
open
source
work
in
digital
Communications.
The
development
boards
are
are
pretty
big,
they're,
the
expensive
ones,
but
we
do
have
like
a
basis
three
and
a
Pluto,
and
things
like
that
so
and-
and
we've
done
some-
some
good
work
there.
So
so
pretty
much
it's
for
r
d.
B
A
B
I'd
say
that's
generally
correct.
Our
our
main
project
is
the
phase
foreground
transponder
for
space
and
terrestrial,
and
so
this
is
the
five
gigahertz
up
and
10
gigahertz
down
digitally
multiplexing
transponder.
So
that's
what
the
most
of
the
traffic
on
the
fpga
channels
on
soccer
is
about,
and
that's
that's,
probably
the
the
biggest
consumer
of
the
of
the
stations
so.
B
Yeah,
no
it's
it's
coming
along.
The
the
downlink
part
with
the
encoder
is,
is
a
decent
shape.
The
problem
that
we've
had
there
is
trying
to
feed
it
with
data
where
we're
getting
some
weird
timeouts
from
the
processor
side.
So
that's
where
we
were
at
right
before
Christmas
break
and
that's
where
so,
a
lot
of
attention
is
being
paid
now,
the
multiplexing
part
is
probably
the
part
that
we
have
not
spent
anything
other
than
a
lot
of
whiteboard
and
and
simulation
time
on.
B
D
B
D
B
No
I
think
that's
you've
got
the
you
got
the
story,
that's
what
we
talk
about
and
also
any
other
way
for
the
remote
labs
to
to
serve
the
community
and
to
serve
open
source
work,
and
so
with
that
I
will
because
I
know,
James
hello,
James
James
has
he's
our
our
lead
for
remote,
Labs
South.
This
is
located
in
Arkansas
and
I.
B
D
B
I
I
talked
offline
with
them
and
they're
like
well.
If
they
can,
if
they
can
manage
to
get
a
contractor
out
to
to
the
middle
of
nowhere
in
Colorado,
which
is
where
they're
amazing
facility
is
located.
So
if
you're
not
familiar
with
deep
space
exploration,
Society
check
them
out
online.
This
is
a
really
neat
project
and
it's
been
wonderful
to
be
a
supporter
for
the
past
five
or
six
years,
but
the
you
know
it's
really
nice
to
have
another
group.
That's
also
attempting
to
to
bring
amateur
image.
B
Interferometry
to
you
know
to
Citizen
science
and
open
source,
because
we
can
trade
back
and
forth
and
just
getting
kind
of
the
confirmation
that
the
way
that
we
want
to
do
it
is
you
know
the
way
that
they
the
way
that
they
saw
to
do
it.
It's
a
it's
a
it's,
a
really
good,
solid
Echo,
so
that'll
be
another
effort
to
bring
over
those
larger
dishes
and
I've
I've
started
floating
sort
of
a
schedule
for
that.
B
It'll,
probably
it
looks
like
it'll
be
later
than
the
lab
equipment,
so
getting
the
the
remote
lab
there
online
will
probably
start
happening
pretty
soon
and
then
we'll
we'll
be
something
that
will
last
through
the
spring
and
I
know
this
is
this
is
about
a
year
later
than
I
wanted
to
do
it,
but
I'm
I'm
really
happy
that
it's
coming
together
now,
and
it
sounds
like
that.
The
physical
plant
is
in
a
better
place
anyway.
B
B
C
B
Is
it
seems
to
be
yeah?
Thank
you.
It's
a
it's,
not
bad
news
that
there's
nothing
going
on.
So
the
the
one
thing
that
has
been
added
to
remote,
lab
West
is
that
we
got
a
year
extension
to
our
Matlab
license.
So
we
have
all
of
the
toolboxes
as
a
startup
license.
Even
though
we're
not
Tech
I
guess
we
are
a
startup
but
we're
a
non-profit,
Research
Institute.
B
So
the
neat
thing
about
the
HDL
coder
in
Matlab
is
that
the
code
it
produces
is
completely
free.
You
can
use
it
for
whatever
you
like,
and
our
experiences
over
the
past
year
have
shown
that
the
HDL
code
that
HDL
coder
produces
is
very
human,
readable
and
of
good
quality.
You
do
have
to
put
in
the
effort
to
make
the
input
code
to
Matlab
kind
of
comply
with
some
rubrics.
It's
pretty
simple.
B
So
that's
some
good
news
for
remote
lab
West
and
then,
in
terms
of
our
the
designs,
we've
gotten
a
tremendous
amount
of
interest
from
someone
who
wants
to
Port
the
down
link,
fpga
encoder
for
dbbs2
over
to
the
zc
I.
Think
it's
a
zc
711,
but
I'll
have
to
go
back
and
look
so
we
do
have
a
customer
who
is
who
needs
some
support
for
building
it
and
porting
it
over
to
a
slightly
different
Dev
board
and
their
application
sounds
sounds
really
neat.
So
that's
that's
moving
forward.
B
B
This
is
a
lot
of
slog
through
some
some
fairly
difficult
math,
but
we're
making
progress
and
we
have
a
good
reference
design
from
Theseus
cores
the
team
that
did
this
for
the
for
the
F
for
the
xylex
fpga,
that's
in
the
usrp
x310
and
they're
super
friendly.
They
don't
have
a
lot
of
time
to
help
us
with
this,
but
they're
able
to
answer
questions.
There
is
a
bug:
that's
they
called
it
a
bug.
Their
limit
is
eight
channels.
B
So,
for
some
reason
the
the
filter,
Bank
or
the
channelizer
was
limited
to
to
eight
channels,
and
we
did
see
this
when
we
demonstrated
this
in
2018
at
Defcon,
so
that
particular
implementation.
If
we
take
that
and
figure
out
how
to
extend
it
up
to
like
oh
96
channels
or
so
then
we'll
be
we'll
be
in
very
good
shape.
But
right
now
there
was
some
sort
of
a
weird
limit
with
that
particular
code
and
it's
the
last
time
that
that
I
that
I
checked
in
about
it.
B
So
if,
if
you're
listening
to
this
and
and
you
go-
oh
that's
stale
information,
then
please
accept
my
apologies
and
I
over
the
next
week.
I
will
get
completely
educated
about
it
and
next
week
I'll
have
a
a
updated
report,
so
we're
looking
to
leverage
their
open
source
code
base
in
order
to
provide
a
good
receiver
for
us
for
the
spacecraft
or
ground
sat
terrestrial
node
for
any
of
these
implementations.
B
B
B
B
One
of
the
things
that
that
we're
we're
doing
over
the
next
quarter
is
looking
for
for
partners
for
integrating
the
spacecraft
and
advice
there.
So
that's
that's
something
that
we'll
start
talking
a
lot
more
about
in
in
these
meetings
and
also
on
Slack
all
right.
Everybody
thanks!
So
much
any
last
questions
before
we
close.
