we are back with jrwr talking about
his crazy hard hat it has
4chan api calls or connections
it has crazy led lights on it
it has a full-blown access point
it has so much tech in it and he has
already impressed us
so much with connecting the defcon badge
out to the internet for all of us to get
to if you haven't checked out that video
i'll link it
somewhere here but right now let's talk
about
his hard hat at defcon
29 so what does it
do it looks incredible here i'm gonna
hand this to you you talk about it and i
will just get
shots of it right now uh so this is hat
chan here
and so what hat chan is is first off
it's 499
leds of awesomeness so this uses a
custom circuit board that i had printed
and designed
uh they're all neopixels in a daisy
chain
and they all support holding uh shitty
add-ons as well so i can really deck it
out with all my shitty add-ons
so uh it's running through a demo reel
from the fast led library here
and it seemed to just work out extremely
well in the process it's being ran by a
single
18 mega that i got hidden underneath the
router there
so the power system on the back is the
newest innovation for the
the hardhat group i'm using a single
rj45 connection to a cat6 cable
uh to handle 48 watts of power
into the hat i'm using dual
12 volt rails coming in from a giant
battery pack which i'll show here
you in a moment i got some voltages on
the back that you can see
and then i got the wireless router here
on the back with my university's log of
rochester institute of
technology so um
it did have a three volt rail for the
saos but three volts is hard with this
much
this much power and the magnetic
coupling issues that i was having
magnets are hard so
uh this all came about for my original
uh
hard hat that i was wearing which was uh
hat chan 1.0 which you probably all saw
at some point
uh in the last four years at 10.1 was
the pith helmet with the
dual led strains and wi-fi antennas well
it's even better is this wi-fi router
which i'll pull up here on my phone
is an image board you can connect to the
open wireless access point on it
and then you can you can post to my uh
post to my hat just like you would on
4chan
and then you can pretty much just ship
post to my hat i've got
five years of posts on here
yeah here we go this is the old board
from defcon 27 going back
i have 20 pages of stuff
you can find copies of this image board
on the internet archive as well for when
i copied it on defcon 27.
so um that actually is how i got my
my career started in cyber security is
because of that stupid hat
so i wanted a conversation piece and
i had a history with that pith helmet
anyway so i just decked it out real hard
and i had some stuff
on and i wanted to provide a service
because i'm a web developer
you know that's what i do in my past
time right so ain't hatch m 1.0 you can
probably find defcon 25 photos of it
from an eonigo but
it's actually what started the hard hat
group
because we noticed that there was kind
of a synergy of people having these hard
hats with crazy stuff on it
um but my my boss found me in the vendor
area
and said hey i need a pen tester you
look like
one mind you
i have no certs i have no schooling i'm
just a nerd
what i'm good at but the best of us are
right now i'm just a turbo nerd okay so
uh and it's just gotten crazier and
crazier over the years for sure
um but this is the the latest iteration
that i've come up with
um so here hold this for a second let me
grab
i mean this thing is truly incredible
like when it lights up
you can see it from across the room i am
so glad he was wearing it because that's
what made me come on over to him
originally
and hear about this crazy like just a
hard hat con this whole mini con that
happens inside def con
it's it's amazing i love seeing these
things
okay so we got a little bit more to the
power here so you can see i have my
ethernet coming in
and then this is where it gets really
janky so i have
two static 12 volt triggers for my
battery
for a qualcomm quick charge 3.0 so it
tells the battery i want 12 volts and i
want all of it
and so it's connected into this
connector here with some a lot of
kept on tape here and it's going into
and i'm surprised they let me on the
plane with this
50 000 milliamp hour battery
this bad boy here will last me 19
hours of run time
with the hat pulling 48 watts
did you get stopped by security on your
way in
they just let it right through they
didn't even respect my bags or anything
i get stopped for a pound of coffee
yet this thing makes it through that's
crap
tsa if you're watching which i know
you're not because it's defcon and
i'll leave that one there um my gosh
like this is incredible
like really really incredible so this
whole thing came on and came out playing
with me
this got checked the hat did in a big
pelican case and then uh the batteries
and the cables
came in with me on carry on it made me
check it anyway
halfway through the flight because bwi
likes to do that
so they're really crazy about that
i mean this is incredible like thank you
so much for sharing this
thank you so much for just the
come on i'm looking at some of these
badges i just tweeted out
one of a kind badge just just it's
amazing like go check this one out i'm
going to zoom in on it right now
like truly truly just
beyond anything else yeah thanks for
checking out the video we'll continue
going around the hard hat table
thanks for watching and hack on
