by the hallway again as for the that's for the unscheduled tracks a few wanna
say something on your own
I mean look as activities downstairs like we're talking about please don't
turn off the hotel TV's
a in that lobby I know it's it's tempting
I think we've had like takeover in any way to help them out this but the
hotel's been great to us
and we're glad that it still standing I think
to ensure they keep standing was treated with respect
the respect it deserves and I'm who knows what the future will hold so on
Soria might give the official entrant um
it come a little better prepare their
are you guys ready to go okay thought your only day to give the round of
applause
well I we have a special that's about cell phone so we have cell phone jammers
appear so
it yeah it actually doesn't matter so
sorry can't wear use or sell for now all rights lol
ultra an assist for free a
little bit about us before we get started the so you know what your
which are in store for I'm senior editor
Make Magazine you guys are make okay because the way people though it always
ask for
now around almost four years we have a hundred twenty-five thousand
circulation 45,000 subscribers on a website as a lot people visit
scrapers there's use community people building things and sending
their projects to us now I our Maker Faire that we do every year
is up to 65,000 people so it's
giant event in San Francisco we'll send you one and Austin
and here's up some other things that we've been up to make see some other
covers were quarterly so comes out
every few months three branches in the craft for people who like to do more
the softer side literally acting and then
I we decided that well what other we're
we're thinking we do so we have Japanese version which is kinda taking off
which is great and I actually like it. I can't really read Japanese
but it looks cooler Japanese
and and that this is
more her business they differed yep so you could probably just like
its risk Ford so two years ago
a I talked about the wave up a project this is an open source
RF jammer which is actually if you look at counts like this
as is the beta and basically you know i i just been releasing open source
hardware
electronic kits basically more soldering
microcontroller programming firmware analog/digital
a that kinda stuff because I think that's an interesting and I found that a
lot of people also interested
in building the sort of technologies especially technologies are legal
for example it's illegal to own use operates L
a cell phone jammer so I'm you can buy them but
there's a chance at the stores will be shut down boats cool is that
if you know a little bit harder love the soldering you can create your own cell
phone jammer using parts from Mouser digikey
us a flick on cars parts you can build your own so then there's no way to stop
people from buying these components kisser just
everyday Electronix that's what I like it's create something interesting from
stuff you find around you cell
our this was an account %ah you know when they're driving and their
talking and there swerving all over cell
I and you know what it's not even think acid resin like a watch how you mustn't
de personne
units prolly get off the phone like you're not supposed to come far and he's
like I whatever
and then so if there's a lot of hello can you hear me now here in a
this an action shot you guys will enjoy this year is visiting
the cap situation may be able to stop sons and other projects in a years ago
sleeping movies oxide it said open source cheesy
303 clowns that set synthesizer from
at twenty years ago more 394 that was
a discontinued by Roland Japan I love people still want these
synthesizer boxes so a friend of mine and I
in when I was in college decided hey let's reverse engineering and because no
pants valid anymore it has been more than 20 years let's make a clone
that again you can build using off-the-shelf parts and you can make
this
to the size is no longer available does what she does not need a
you can build your own for 200 suck and here's some
you blink you like kids just want to show a couple projects cc
we're coming from this is a LED
bicycle wheel animation kids so you can
make it pac-man when you like like and I also
did some so that small educational kids is the many pockets just
video persist division toys for like under
seventeen dollars and I like the idea of low-cost
introductory electronics so when you leave its bills
so what's cool is that the tall man who's giving the top
after this he should definitely stuff stay for she said well you know I want
to build is bring sheen which is thing that makes you trip
Anna I didn't work for me but like he's he's not how the seventies he can
explain it %um sure you well
in an hour and he took this mini pocket and he modified it
and he even gives workshops down I think he's doing a workshop either today or
tomorrow on how to build these
using the many pockets at school a and this is a
out to extend mp3 charger so it's another
small educational kit am and this is a
another thing I worked with Mitch Altman on he invented the TV on
is a little remote control a contract TV's the following the TV gone is
although it's
its awesome and it turns off many TVs only works up to like thirty feet
which is totally not enough so we worked together
to build a version that you got to 200 feet and and
yeah this one %uh made its debut at CES I don't know if you
saw to commodity
it's good it has exploreli diseases like wide and narrow
and its cool is that there's a community in the form of people who are modifying
skip to like force not enough money
eighty LED's any to 6 volt battery pack I need to be attached to Mike
captain so everyone look TV's turn off there's
harkin modification love you know these existing technologies and because it's
all open source is still like
I have to understand that shipping isn't extract
firmware and use acid to take the dye out now it's all open source
it's easy to hack its you know kick-start so you just go in and say
L you know how to connect LED so I just Adam on that's it
okay cool this is hacked I can do and if you're younger this will get you started
so you can continue on to more advanced and a few lately I've been working on
Arduino based projects and open source my controller platform says is a
DIY GPS logger and tracker so
India maybe next over the next conference we go to will talk about some
the projects are doing with that
how many people here know about are green our player yeah
laugh a lot so that number every time her out it was like 60 before was like
one guy was like
we know K
so lowering it be talking about today is a new kid is a SIM card reader kit
so I don't actually own a cell phone so on a cell phone jamming other compatible
but I think it's interesting that you know a couple years ago maybe ten years
ago everyone was like million to reading next rapes
but nowadays we don't really get me now there's actually a RFID style
cards but it's interesting that I never actually learned about SIM cards and
even other in
almost every phone I and technology behind Sanford is really interesting
but on if we should try to find online was really kind of archaic it's actually
beautiful
me understand so wanted and build something that even though this is sorta
all the technology that makes it really easy
and straightforward to understand House Inc artwork and why they're secure and
how to crack that security
and one other thing that this is a
project we worked together as we decided to start a laser etching
business and open source lazer tube is a new york city so we got this laser is
twenty thousand dollars
and we paid off in about six months and what we're doing is
laser etching laptop so if you see laptops around we act these
I'm so we take perfectly good max and void the warranty is and people pay if
up
configure Steve Jobs nightmare we also tried to do other things like this is
fair
we put CC instructions santori so
we actually we put spaces a people we don't like on tortillas and then we eat
them
and it's like a weird like a laser etching
Millennials who do so I we put all this information out
and is around 20 laser shops and open since we did this little files
everything
but mostly because we retired people emailing us saying no
I can't come to new york city can I send you something you don't want people
senator
their laptops so now people and all parts %uh the world
are starting their own laser getting businesses okay so the intra
but the rest is is going to be a lot faster so two years ago we came here and
we did talk on service engineer
where we we actually did a full talk about that's the stuff this reemergence
of hardware technology
something new era love packing in freaking and take a dollar to video made
by accessing its online she have seen how much people have it
but what we what we thought about so we've been going to this conference for
like 10 years have been
I enter the first up I want to be on hold but I think that was about ten
years ago
and another thing we know is we look at some the speakers here is
I think there's a lot of people are talk about this is the last hope
and theirs is understanding or at least a feeling that
the hacking see as we knew it in the nineties and if you're
17 maybe you don't remember this but is kinda dead
but not like a bad way like oh my god I have tragic it was on its deathbed
we get oxygen but couldn't make it but there's definitely been a transition
from this early hopes you know
1994 to 2002 2002-2008 up
and there's also a lotta histology you know these conferences
are filled with things from Lee blocks red boxes
splits buffers IRC I text files
truck jerks getting kicked out of construct I'm always something you're
such about some other things that happen in like the nineties acting that you
liked
life's China's stuff yeah
yeah significant yes if that's very passe
yeah and actually and will say pretty soon it would have been the worst thing
we could possibly done probably in the late 90's but now it's like
ok all like now it's fun so it's interesting times to change
%uh so now
there's other things so instead of doing things that we all used to do
now there's white papers everyone security consultants doing
had testing they have put deals urs wait there's
a boondoggles yeah
the car to the word out they were dried its its kinda this
new old and
so we notice was that as some things and some things began
hardware start based on number people here
new Barbie no that's a lot two years and people are
buying markets makers things that
working on for a while we can't seem to keep up with demand
more and more people wanting to do are greater than ever before
so upset is an engineer
is something that we put together we wanted to look for
not back but we also want to build on the past so
I we like the idea the entire just technologies
that got us all here up and we think they're still
interesting but what we wanted to do is pull it all together
and show it maybe in a modern way so I made a video
and its core kind like a short film we just
debuted its like a few minutes ago on the web and we're gonna show you on some
snippets I its again always be non-commercial not sponsor we're gonna
try to do these is often as we can
I it's only for people like all of us here
we don't think anyone else is gonna like it kinda hope they don't
either I will say so
a stood but the the introduction yeah
one other things that we wanted to do to is a a lot of good
things that lamar's worked on she made his office box so people
take them used take the Sox box and then make interesting music so we wanted to
use that as our soundtrack so now we've got a bunch of commuting
there's also artists are using processing which is part A
the Arduino develop an environment similar ID
they do interesting art sale we talk to an artist who
does really interesting art with processing so I this introduction and
we're gonna
show you some some other snippets so out yeah picking at the house lights off
from now Ford that would be great
I don't know if anyone has access okay
issue
yeah pretty loudest think
list
past
times okay
so that's our checks now we're gonna do is skip ahead
sue the first part so what we did is we talked about GSM phones
SIM cards all that stuff you can download the video later
up and him what we do is kinda demystify sum up what goes on behind the scenes
with electronics
so up we took part store
evolve the up things that you'll you'll need
should so basically this first project is
you know every GSM phone at the sim card in it and
such a lovely few things going on in SIM card love the stuff actually
explore back in 98 suing eagleberger cracks the comp
128 31 encryption scheme basically an
love cool data that stored in SIM cards even today
for example at the last 10 phone numbers dialed from the phone even if you've
deleted your call history
and sometimes sentence he just misses are still stored so
even you know it interestingly enough even know SIM card cloning was only
really popular in the late 90's
if became popular again because that was hell I sons were originally
cracked was to duplicate samples but changeable for the information she could
use a different character than AT&T cell
but unfortunately I looked online for some information
all that was very focused on just either forensic psych really hardcore friends
its information
or basically how to hack iPhone so I wanted to sort
create a more generalized introduction two SIM cards and Heather
read that data SIM card doesn't do that by at building a very very inexpensive
a SIM card reader and show how to do that in your own home and then one
the free and open source software on your computer as for this fight for you
can sort of the house lights
that's okay so
film which will set up here got my multimeter commuter
will be used for testing circuit the few
sector which will be used to get rid of all the fumes soldering
and my soldering iron I also have a
next vice holding the circuit board like work on it this is really useful
you can use third there's three parts
%uh SIM card reader there's the power supply section
there's the oscillator section and then there's the serial port and scarred
interface section so
for the power supply need and I know battery
older will connect the battery at this for
a one in 4001
protection diode and 7805
send me if I was coming to righties mini version
Big Brother version you can use either one the power supply should also have an
LED to indicate when the device is on
so an LED and the 1k resistor and then
to keep the power supply functioning well
a bypass capaz passers necessary this one is a
100 micro farad capacitor and this is a small ceramic
second part of the circuit that we're gonna build see also section
that's the part that generates 3.57 megahertz signal
sent to the SIM card that lets it when it cracked pottery ily
3.57 megahertz crystal to
20 pick up Eric passes earth in one make your own
resistor 2k resistor and a 74 HC
04 not gay you can also
get a socket at the gate into X the third part
over the circuitry is this your port and SIM card interface
the most important part here is to get a good SIM card holder this allows you to
but the SIM card and block it so you can create
a good connection with it and a female db9
serial port connector this is what you'll be able to connect the computer
also need to zener diodes
anywhere between 3.6 26 balls perfectly fine
and three 10k resistors this part is what allows a
10 votes to report to contact with if I volts and card reader
safely also any NPN transistor
any SIM card has a bunch of contacts on the bottom that allows the SIM card
reader
talk to it now there's eight or nine or 10 contacts here
but only six little ones are really important the SIM card looks like on the
bottom now there's a sex contacts
in the middle there's one one big contact and that when they contacted
gift
sidelines that's the ground attacked that's used for power signal ground
underneath that is the programming contact that is by the manufacturer to
program the SIM card
where factory movies and napping that will be using that
serial i/o pin that's right beneath that that's how the computer talks the SIM
card
on the other side is the clock
that's where the reader sends a clock signal to the SIM card chip
tell it what the cracked moderated make sure to be using a 3.57 megahertz
clock which translate to a 9600
bought
signal above that is the reset
that's how the reader says hey wake up for a to talk to you
and above that is the five full that tasted powered
said
well
I'm a way well
dark
all well
well
I'd
well
ok
mark told
funk
all how
I all
self
car side now
the SIM card reader slide in the SIM card
that
it locks in
in the nine volt battery really
now connected
let in software it's like this year sick
for Windows public first thing will do is extract save dismissed
SIM card some phones don't overwrite seems
00 FF you can actually extract deleted SMS is
every SMS message has
recipient sender the message
and steps you can see last last
self sleep
this is all contact if SIM card sent
used as a bat sometimes
excellent interests
contact gonna look at the same information at this lol
mission serial number last location phone was used in
statistics anything just just take the reader
finally if you're interested in the local paper called a douche
the debug window see you and information was sent
art now let's say you want to close well there's no way this
Park fire the secret key
but what you can do is perform known plaintext attack
and that the SIM card tens of thousands but I music's offer
right here and if it works out to get the key
but I most since it doesn't work on any longer
and I'll sell can't disable sums sell our generous offer takes about six hours
let's give it a whirl year
do
I mom
model right so let's see how I made out
looks like that we were able to extract the SIM card
Noah we would need to do is copy this information to rate it will send
this project done writes that was a SIM card acting to the
a
it's very hard to make electronics exciting and I of a succeeded
try to get some techno music said cervix part is pay for hacking
up and a think about pay phones is there's
all being decommissioned pretty much going away there's millions of them
available and as we looked around I saw these pay phones
and we wanted to do something caught that we also on still have a red box
cell we like what we gonna do it this way so next act clip
so I'll
we decided to procure some self
some payphones to do some projects with
and probably so it was not just for the intro for this video I it's not just
explain it very quickly
but you know muscle here where there's to cut there's basically two kind to pay
phones out there
there's a standard telco style pay phones and of coconuts
and calling phone kustra
clean operate telephones and other actually have real computers insider
them and when you pick up the phone staked out town
and all the calculation about how much money to put in with this time to hang
up for a Skype call
all that is done inside the payphone up but
that took a pay phone switches had pretty much the same design for like
thirty or forty years now and because I didn't have my controllers
microprocessors when they were first invented all love
the thinking in the hard work up what monies owed in with a question but it
happened on the switch sides right at the central office
so what that means is that these patients are really done that actually
no electronics in them very violent riots in them
and also all the control is done using really strange voltages
that occur on the switch side so other will show how you can modify payphone
for home use
all the cool stuff that papon's do you can't get out of the home phone line
you can't get it out the voltages that come from home
home phone line to suck a special up phone lines which
and but you know we got this pay phone
and we decided you know the stuff is so cool we open it up and
I've never actually seen the inside of a pay phone and so i thought well
I step back pay from from the outside but at the nickel package from the
inside
instead so we can have split up the project into three parts
for parts and we show some really cool stuff
you can do is pay phones especially telco style so
let's just play the video and will be sign for
and you can play with PayPal have it the vendor table downstairs its
not plugged in here but will have white boxy can
packing to look similar a
which will look for is
fellow goes bill names anything that says you know
the local telephone company every benefit fund has its own
Tiki this used side
and her with the handset
whole front be careful cuz inside
there's applied but perhaps
kicking up paper for home use
pretty easy first you'll need a telephone wire that has
telephones fate logs on one and and
standards cooder feet
the telephone spade lugs
through the back fell then connect
the red wire which is the
bring to this terminal block
marked are second connect
that green spade lug which is tip to
the tear apart T
finally take the black and yellow wire it or not going to be used
anti than to the ground connector that
coin counting Secretary has to be jumpers so that the phone doesn't expect
according to be inserted Fort Lee
call now that's actually been done here by
jumper and in five in pin 8 on this flood
otherwise you can just solder wiring to to
now simply plug the pay phone at your home phone line
or in this case avoid box now's the time to test the wiring
pretty easy just call for frontline
ok
there is a distinct parts for PayPal on the left there's
Quoin sorting mechanism which takes valid currency and then
below that is the coin hopper this records are stored wallop
pay for makes phone call and then this is the quandary is a
as controls whether point in the hopper go into
Queen box or if they're trashy on the right side there's
the bell the phone line terminal block
that cling telling oscillator and the connectors and jumpers for
to have to the Paypal cares for the total I would live now unfortunately the
total lighter with work does pay from before
captured and the other half the pay phone there's the headsets which %uh
detector
the telling passengers on the back and the DTMF encoder and walk
to the Queen assembly first flip slash
then reach and and pressure on the wire right
part just comes out to
open at that point assembly schist but open
these magnets also with
calling is inserted into the payphone it travels down the chute
now in this case a quarter will pass by quarter separator
only if it's the crack size in WAT will overtake the separator
cuz it to pass past this magnet this magnitude than any current inside the
conductive metal up the point which costs to slow down a little bit
and bypass this year to continue into this one
where that point except the coin and drops
into the hopper where the payphone awaited switch tells it whether to
put that point and click inbox or return it
their trenches those papers ready to make phone calls from home
but better much fun well im jus modifies pay sound so
part quits for ok said there's a totalizing I want to add a sensor
checkpoint
a wonderful one here on the side of lower this entire winnie is a breaking
sensor
it in mid-air detector and when object is between
the tentacles of kinda flat peace card
supple the clue
onto the hopper trigger right here clue the flap of the hopper trigger
and now it's time to solder first part
is 0
well well was what's
well small was
what's wells
well phones
wells workers
last you home year well
files ways
this is the coin detector and phone controller that we start with
I as a past client using four AA batteries came to the
battery pack and this is the power supply has just
capacitor just to regulate the power an overall indicator LED
down and then I fucked up the
sensor that will detect when acquiring have gone down the flock
at that's connected to a flat which will
take the small piles that cultural center and convert it into
steady voltage which then controls telecom relay
that's a really that specifically designed to control the high telecom
voltages at work of a five yr old
so it's perfect so testing the sensor
type card from them include sensor
into the pic
know it would be this sensor make
two wires with spade lugs on hand
caked on spade lugs to the phone line ring and the others face blood
to the peso
now playing in those two jumper wires into really that clip the clean relay
open
now stand the test
our system turn on the battery pack and
pick up there will be a downtown
now press on that quite hopper trigger
sunsets million thousand
sir
now with the fam back together took the Queen out later
close it up now know they can make a phone call my speck case on
ballistic quarter now playing the Queen elevator make sure the careful
sensor replaced finally
wire up above sensor between the power from the battery pack and the circuit
board
so when the switch is pressed power to the forget cat
cliff a sense if so when the phone is
on ok the switch is depressed to requiring either I'm going to crimp on
some
loves onto the switch contacts
for these wires to the small hole in the PayPal bottom
into the power connector up
this paper an income with the point not someone YouTube look up instead
spot in the back finally
stash power supply and a circuit board from but the for the coin boxes
unlock it again with the Tiki slide on
of
now close at the hopes
no doubt I'll
its exporter I got out I'm somehow
front is done
cell make a payphone project works pretty well
but i wanna i'm open old-school charm to it for the Queen going directly to the
Queen box reprint an hour 27 hopper
and then when the phone is how I have the coin really will activate
and the final top into the point box making nice chick
time to crack open the paper and this is that clearly that we could open
now I wanna and club at to after this really any 230 volts
but only had a hundred rubles kicking around her cuz hooked up to a payphone
phone line
the phone can generate 48 volts but didn't have enough current to drive to
realize someone I have to build my own DC power supply from the battery pack
and clean box
for sale do is build the high voltage power
I to
this
I
it
close
class this is a basic dc-dc boost converter based on the
Lt 1073 chip this ship actually doesn't list all the work
all that's required is an inductor Schottky diode and some capacitors
for the open output and earth just to set the up footage
the input battery pack power comes in here and the output 30 volts
comes out of the screen players before wireless up to our
existing circuit and went to test the voltage just measure
for the multimeter the village with between the two liars should be around
variables now a good time to test the dc-dc boost converter
and connect at the converter to the switch
so that's only Howard when the phone is on ok but
remove the spring from the Queen relay and then try testing the two
to promise to the Queen really make sure activates
plug in the power so it's fully activated when this phone is on hook
moved it clean relay return spring this will make it easier to activate word
judges with the clean up our
connected 30 volts output 22 connectors for the relay
G in this three here the relation up today
wanted to verify to work attach the problems currently
taking a one-way makes the going going to the coin box
headed the other way the quiz we're going to return shoes were nice things
about the West elected pay for designs is that there's a little reed relay
wait where the Queen detector is that is at once the Corning
we lay activates this disconnect and the really I'm at the opens
look at this board down a little bit this link it fit later
and they can use the extra
the project then put the circuit board a little baggie the sill protect the high
voltages from touching some other
for that for okay
everything Deccan Queen box and close up a felon and test this last long
to try it out pick up the handset
and a support that the court is in the hopper
Hannah clearly the possible box
so I've got this
payphone to live for home use and I've taken it and
reverse engineer net and made it so that now requires coins
to make a phone call and also added the coin hopper and Queen really activation
but there's one more hack I want to do on this phone before I get into that the
point understand how these damn papers keep track of how much money's been
answered
in this paper on the total I there's been taken out it normally sits here
and hassle arms that sticking to the Queen validator
so that when it claimed falls through it triggers
and set up for calling town of lipid pink box here
the class letters a passive also that generates 2200 hurts at 1700 hurts
you can try the coin toss their pretty easily connect one diet
said and another diet pin for
tough j2 clip pin set into that tip
and pin for the ring
now into quarters assertiveness
pay toilet text that and it triggers the quaint
oscillator for quarter five times ok
now that toll goes down the hall is detected by the switch on the other side
the such looks at the current call rates determines how much was the deposit and
how much money is at and
asks the user to please deposit more money necessary in the late eighties
some clever person to read the belt just as many wall or
just have headphones work for observation and determined that
if you play this twenty wonder assumption hurt tens into the microphone
it was good enough online and switch and yes I did before thinking
the totalizing quite also army those towns and that's what red boxing
for let boxing became much more popular when it was noticed that the dual total
two frequencies from the Queen to ask their
addressing fortunately towns generate when you hit the star key NFL
and the last time the perfect pushups whatever Chris of that are striving
the DTMF decoder chip to make peace special calling
of where counts you don't need a point of litter box you could use a DTMF
generator
like this old Radio Shack turned out this way sixteen-years-old
all they do is change the crystal so
open it up and talk about the of crystal for this
a 6.5 factory six megahertz crystal now that I will emit
the same towns necessary when you get this turkey
now due to very sad to fry measures the emergence Cocotte
an ATT def taking a pay for online service when boxing is a rarity
it's pretty much impossible to do anymore that will change come down in a
box it would like to use it
so are they doing a lot of highest-paid thoughts like red box out
Queens for the didn't want to use
and eat enough to cover chip if the chips are used in
you know old voicemail systems like pressing one or two or three would
you open a lot to close at only uses chips and studies in the crystal it's
supposed to be used to that
and want to change it to a different crystals the same one used to hack right
boxes
so that both of them are looking for the same frequency towns
now to detect when the star key is pressed that the same as Redbox
while
where
mom mom mom whoa
the
the okay now's the time to test the red box time detector
here circuitry for the red box detector now I've got the DTMF decoder with
Newcrest also can you take red box towns
and I've got this selector lot now I make sure the only when the star key is
pressed
well alaska hi and useful indicator LEDs will
blink when it to text around Boston that's very useful for debugging
to connect up to the handset and listen to the audio coming for microphone and
winter jacket
external clock felt this is the reference crowd
number eleven and this red wire
is from the handset makers from the microphones that's gonna be audio
abdicated the train line from our Relay
and jumper that just so we can do this test having to worry about the relator
of okay pick up the handset will be a downturn
and you'll see that this board is let the Greeley the start
now red box you'll see that the green LED lights out because it detected the
star
so physicist and certain to work
but there's one problem now because the payphone is designed to be queen for
status
we don't connect the phone line until we get money or
red boxing no there's no power to the microphone
so the circuit can actually listen in on the microphone because there's no power
but worse I was pretty easy by biasing
handset ourselves by using a 50 power supply
Leslie the internal power I've headset supposed to be five also its kinda look
instance for soccer fly audio input to the circuit they'll come from here
and centering now text the ground reference
echoes appear now to connect
the fire started the handset that goes into the handset
10
as telecom really double felt the need to actually two switches inside
and then use that second switch to connect and disconnect that
ice power so only when we don't have the phone line connected
here will there be powered the handset this way r5 also compete with the phone
line football's
one more thing to do that's close up pics okay projects done
and raise it pick up the phone no doubt own
get my hand the red box now wat Kost
cops you
you
to cesaria on
the way the way this place here
like Hong Kong style like it's a little bit of so we're gonna like Chinese
like yellow to they don't have it sightseeing in the middle where I like
such as head of
yeah so this is also an HD you can download the one gigabyte
by you know actual size version you know have a big enough screen
up and I we hope to do one of these every so often
about some of the older technologies kinda with and it was too
not just yeah some special hope memorial
addition yes so you know using this video and all the
source code schematics everything we put on such as an engineer dot com
you get a pay phone and dual all these projects you can build
what are the SIM card reader so we have time for questions up
yes actually 10 minutes so if you have questions haha up
up not a you to go the microphone where
you rip your wannabes telephones whether some in the lobby do you have a truck
yeah you because there's 2.4 million
pay phones out there but does not anymore 234 million customers who pay
phones
and they're getting uninstalled if you look at our new york Elsey boots
and the pavements been taken out not stolen it has been decommissioned
ATT's been losing money on pay for it for so long
they were required to keep provide papon service do that
filbrick ill health stuff online so EVA up
crazy first recently they were free from maintaining a
its own out there yes on and selling them on Craigslist I have
an RSS feed but just as pay found and it's for everywhere
you get really weird stuff obviously from Craigslist and pay found I
doing the one about fifty dollars yeah I mean if any cheap nowadays
and people have warehouses for these so you just it believe it or not if you
look from you actually find a lot
just make sure if you want to do this hacking to get down when these
old-school 1c2
22 telco payphones because again if it's a coke II
I know you can offer for home use but it's more complicated
because basically just pick circuit board so make sure when it's open it's
like
mechanical all again along parts like to camp stuff
thank you by
evidencing with the your newer technologies
specially with like building computers stuff motherboards are actually
phasing out the serial port yeah and I was wondering where some the
alternatives because some your projects actually have serial port
entries and well there's still a lot of computers at to have serial ports
but likely to get a USB serial converter for like 10
dollars I'll social media just doing USB on board is a little difficult
so I was so real and then it's like elf you have no issue for this a fifteen
twelve dollar adapter that you can get a Radio Shack that's not
too difficult alright thanks one of the things that
a lot of our kids at making some tickets and lamar makes they have a serial port
to communicate
with them and obvious like that but as you're saying serial ports
things are changing it's not parallel port I mean people
your reports are still like not completely obsolete
so one of the things we're probably gonna do is have com part of a kid
are the USB part already assembled that usually surface mount and that beginners
can just do all the rest
with three holes so that that's something we're doing on the good side
with electronic manufacturers you now
we don't have to weed out of control still need to do like speed were
a you mentioned %uh we know here um you
there's something called wiring which is like the older brothers that were
I'll ought to be no would you ever consider making projects for
some got some I I think wiring is really awesome but is just
much more expensive and I like the simplicity and low cost
and near commodification nearly
Arduino hard work that's why I've been focusing on that
many wiring for the think about a hundred dollars that's three times as
much as far as we know
so you still about 50 pins two serial ports
yep the I found that a lot of beginners projects they don't need fifty pence or
like I wanna blinking LED when the doorbells pressed so like
this allows them to be something simple like that that's the only reason
but where is excellent and definitely a and you know a good choice to step up
to who thanks what about dialing into the payphone
an so at this time display phone doesn't allow dialing in
but it's actually really really easy and we decided
the didn't make much sense for me to do on video but basically
I a full-wave rectifier SCR in a couple resistors
and basically when he gets the 90 volts on the ring
voltage that set up the SCR and connects this online so you don't have to put
mclean
to make a phone call thank you you can do to help you could build this into a
video
and senator I don't think I'm gonna have a link on the web page how to do that
but
we decided like you know this was enough the phone hacking
to get the information for the simple
and the information sciences engineer dot com just
this interviewing owners I can if you in like 10 minutes until after our talk is
done
it'll definitely be there but we can right now because we're going to talk to
you have to get online I take up the wifi
spot to the website yeah we set to release the files tragic
okay and I think we're officially at a time I just don't legislator
lol
