i
good afternoon welcome to my october fourth scheduled stream
and especially welcome if you tune in after having watched my dwarf 
fortress stream a few days ago i'm probably not going to be doing some 
more streaming of that particular fortress and you know i it was nice 
to get
some other content onto the stream but it didn't prevent result in a 
huge amount of feedback or or a whole lot of subscribers or whatever 
else and
streaming it is less fun than just playing it for my own amusement so i 
am going to probably continue playing that that save i was actually 
doing that a little earlier today
at the time that i had to stop to get ready for this stream and do 
other things we were just in the middle of aware lizard outbreak so i 
dunno that'll probably cut down my population a fair bit
but i am pretty much at the point where i can take care of goblin 
sieges and maybe if i can figure out who all the weird lizards are i 
can send them out into the goblin siege and so a little bit of 
excitement there for the for the galapagos
anyway today i am back to what is more or less my usual kind of content 
here
i'm going to make some more do some more work on the qoyllur v c f's
now these are in pretty good shape now i pretty much just have to put 
the put the eye sees in the sockets to final assembly and do testing 
and adjustments on them
and
you may recall from my guess it was two streams ago i did the unboxing 
of jack sockets that came in from newark and there was a problem with 
that because i had ordered five hundred of them and there were two 
hundred and ninety eight in the box i counted them on stream and later 
i went back and counted them off stream to make sure and it now def
attlee two hundred ninety eight
i weighed a sample of jack sockets and i looked at the shipping and 
tracking information which said that the box weighed three pounds and 
even without the weight of the box and packing material just five 
hundred of those jack sockets we weigh more than three pounds and u p s 
rounds up so they sent me a bag
talks that could not possibly have weighed enough to actually contain 
all the jack sockets that was supposed to
so i sent an email to newark customer service and i got an immediate 
automated response saying here is your case number and then i heard 
nothing and that was tuesday of last week so today i went to there
chatbots i hate trying to deal with chatbots for customer services but 
that was what it said in the email issue too but the chap out was down
so then i phoned them and spent some time on hold and talked to someone 
who
let's say it sounded like she was located in about the same place as my 
pc board contractors
and she said that they had a record of my complaining and they were 
still messing around in the warehouse trying to figure out what was 
going on
but they should be able to deal with
sending me what i want is for them to send me the missing parts now 
there goes my phone and i think i'd better check it so i will put you 
on the slideshow briefly
the
okay that was just someone who thought the side from them and i hadn't 
so i think that my number is being spoofed by the
by the phone spam people anyway yeah newark says that they're working 
on it
if the the the best resolution will be that they just send me the two 
hundred and two missing jack sockets unfortunately its also quite 
possible that they're going to instead like refund the difference and 
in that case if i want to order two hundred and two more of them i bet 
they'll also have raised the price so
you know i
well we'll cross that bridge when we come to it
i still feel like i can't use the ones that they did send me until 
until it is somewhat resolved just in case they tried to demand that i 
ship it all back which i think is their main way of dealing with 
problems that you know that there's a form on their website for 
requesting an army
and that that seems to be what they think is the way that they solve 
every problem although if you didn't ship me enough of the parts me 
shipping back all the ones who did ship me doesn't really resolve 
anything
so i'm hoping to avoid that
anyhow
i
what i'm about to do now is count out
some of these trends conductance amps
ah the thirteen seven hundreds
huh
because i need one of these for each
for each toilet
huh
and these are the ones that have been discontinued so i think we are 
now not sure if we're still in the in the last time by period but i 
think we may not be i think it may now be too late to buy the new from 
the manufacturer
so i did do in a lifetime by
and i'm actually not yet through my earlier supply so i'm not i'm not 
taking into the lifetime buy yet i have a couple more rails of them 
here from my previous batch
but that'll be a thing that's on the horizon
i have the off camera here off to the side i have a big box that is 
supposed to contain all of the
all of the elena thirteen seven hundreds i need for
the projected lifetime of my of my company

these can go right into the boards











what did i just do
oh
i just bent all of the
leeds on there
sideways
i think i can
unbend them
with needle nose pliers but that's annoying






yeah

yeah a little careful attention here in the
should be fine




i'd hate to have to throw off this chip given that its one of the 
pricier ones and
one of the ones that are no longer made


so its good


i can spend a little


hair





alright everyone at the sixteen legs its in a little socket properly
he will try not to do that can i





being able to have chips and sockets is
one of the sorta little luxuries of
building things through coal
he means well i have the opportunity to put things in backwards but it 
also means that there's the opportunity to like swap trips around which 
can be useful for debugging
or some people think they can upgrade things by putting in a better 
chip on them
yeah that's rarely going to be the case with mine because i use good 
chips right from the start
ah
but there are a few little advantages to being able to put a
hi
for the chip in a socket which its pretty close to impractical for 
surface mount
some of the early surface mount chips
you could get sockets for them but the current generation
short of like the manufacturers testing apparatus you you can't really 
have a socket that he would put on a board

and if you're doing surface-mount to save money then you wouldn't want 
to anyway because sockets can with the smaller chips sockets often end 
up costing more than the chip
like these telos of enforce the sockets for these cost more than than 
until seven forty chip does
a socket is like a dollar a nice chips might be like fifty cents
not the case with the fancy
oh thx tho those those are more like two dollars each
and although they're not in the qoyllur
ah i i certainly make
i make modules that include some chips that are over ten bucks
and so for those you definitely kind of want the chip the socket 
because it helps helps preserve that expensive chip right you can test 
your board before they put the chip in the socket if the chip is bad 
you can swap it out and so on
i was thinking of middle path because i was working on one of those 
today
somebody ordered one of the custom panel ones now
longtime viewers will remember
the the whole custom panel project
i spent a lot of time on making a batch of customer painted panels
i wonder if i can just put up the
slides for that briefly
i think that at this work it'll just show slides with maya yeah that 
there is a a test piece right there here's another test piece i was 
using discarded circuit boards for the test pieces but
then once we get past those
there will be several
unfortunately i don't have an easy way to skip them so we'll just wait 
a few more seconds and then we'll get to see some of the the real 
custom panels

here we go this one was done with a tape resist and then there's 
another one that was done by marble dipping where a spray paint onto 
the surface of water and then dip
dip the board or the panel into it
so you get the idea there's a variety of custom panels here that are 
those originated with them with a batch of panels where the regular 
contractor screwed up the colors
and after we'd established that that it was their fault they said okay 
you can just keep the bad ones its not worth shipping them back to 
germany
and they gave me a new batch with the proper colors so that was good
some of my suppliers have better customer support than others and to 
the panel people do a good job



but anyway so i did the i did the custom panel project and largely it 
was sort of research because i wanted to learn about these painting 
techniques
for possible future products
but i was also kind of hoping that i'd be able to flog off the the 
finished ones to try and make back some of the money that i spent on
the experimental supplies
and so i've offered those at the same prices as regular assembled 
modules even though that's not really
good economic i mean if if i were actually charging how much it costs 
to make these i would have to charge a lot more for the custom panels
and they've been online for a couple of months now
and just yesterday someone actually put in an order for one for the 
first time
so i was pleased to have that


there were like fifty or sixty in the batch and i'm guessing that they 
won't or very few of them in fact will probably sell but each one that 
does sell is
better than it not so



hadlow to xiii clean











the other thing that's been taking up a lot of time
i
has been the writing up the manuals for the
gracious host the next module
because this the gracious hostess has a sixteen bit microcomputer in it
i want to have a complete basically programmers manual for it
so that that really implies a lot of work writing
there's probably going to be a couple hundred pages of documentation 
that
people can download for this submodule
and its a little hard to stay motivated because i don't really know i
that i'm doing anything except amusing myself writing this book these 
two books basically about how the module works i don't know
that there's going to be any significant community of people trying to 
write programs for it or
even with the best explanation i can give them the best documentation 
its not going to be an easy pro an easy modules program
i
and it unfortunately requires some tools that are free as in beer but 
not free as in speech
and that our happened to be copy wronged versions of neutrals you know 
if you run the exe c sixteen c compiler it puts up a copyright free 
software foundation notice because it really is the free software 
foundation's canoe se
with some minor modifications to make it work for this rather unusual 
cpu core
but the the fucking vendors are still going to try to charge you a 
monthly fee for a subscription license to use this
this code
they are really really pushing the boundaries and honestly in my 
learned opinion as a non lawyer theory they are beyond the boundaries 
they're breaking the the license agreement
but what you're gonna do i mean the the hardware is actually good 
hardware
and these are the tools you need to use it not actually the c compiler 
or my my firmware is not written in c its written in assembly language
but it amounts to the same thing you're using the new assembler and 
static compiler
with just enough modifications that you can't use like the the canoe 
assembler that you will get from canoe


i dunno if i should say this but there's a character in there
in the modular manufacturer community
who
let's say he is known for his abrasive abrasive manner
and there was a discussion on the mod wiggler while it was muffler in 
the day
of i forget what it was oh yeah it was about whether manufacturers 
should to publish their own test results
and this guy said something
and although i wasn't a huge fan of him personally he was right so i i 
posted in support of what he'd said
and he responded with this bizarre rant about how i shouldn't lump him 
in with the vendors of three thousand dollar speaker cables which had 
nothing to do with the subject matter of the discussion
so i got pissed off and i i've really had no use for him further i 
won't buy his products i won't recommend them and i'm not mentioning 
his name on this string but i later we still exist in some of the same 
places on on the net so i
later saw a reference to
how he'd done some some work for microchip corporation on the pick 
twenty four
the the same make a controller that i that i'm using and the gracious 
host so i don't know what is engineering contribution was but it amuses 
me to think that he's like there he is or was there a hired gun manager 
of license compliance because
their license compliance with the
the new licenses
about as good as i would expect from that guy






















okay so all of these have their chips in and they are screwed together
and in principle i should be able to just plug each of these into power 
and it'll it'll work now really that's not the case because first of 
all i have to do some quality control tests to make sure that the 
powers not sure down these if you if the power is shortage and you plug 
it in to an unprotected supply then something's
to go up in smoke most likely some part of the
of the the module that's pretty unlikely i don't actually see such 
problems very often but there's a quick and easy test i can do to make 
sure before i plug it in also i'm using a a protected lab supply that 
limits the current so even if they were shorted its unlikely that 
there would be enough current that would flow
to actually do much damage the other thing though is that this module 
has to
i
two trim pots here in the true sense of the word not the misuse of that 
term that people sometimes do in iraq to trim pots for adjusting dc 
offset and dc offset is potentially a significant problem with these 
that it may not even work if the offset is not properly adjusted
so i'm going to have to go through that routine for each of them to 
make sure that the module is going to function as a filter and not just 
be lockup
at a fixed dc voltage
sock
for a third of businesses
at this point
is to check for shorts
i dunno if you can see
the display very well and
but its not so important anyway because mostly we we use the the 
audible
beep indication from this
i've got my multi-meter sat on combo combination diode test beep 
continuity mode its kind of nice most most multi meters have both 
those functions but its kind of nice that this one does that both in 
the same function so the same setting on the dial so if there's a 
continuous
its a solid current path between the probes it'll beep
like if i touch them to each other there
but also what its trying to do is its trying to force a mila amp of 
current between the probes and if it can do that at a halfway 
reasonable voltage it'll show the voltage on the screen here
and from that i can infer because i know it should be somewhere in the 
round range of about one point six to one point eight forward on each 
of these connections
there are three
three three power connections here on the ten pins of the connector 
they duplicate across the pins so i'm going to try forward and back 
each of the each of the three combinations of three connections that's 
a total of six measurements
and i should see about one point six to one point eight on each of the 
forward connections and
that just this one which means out of range on the backward connections 
and if all that is true then i can be pretty sure that i don't have any 
power shorts and i don't have a chip plugged in backwards which are a 
couple of the biggest problems and most spectacular problems that can 
occur in a
so there's one point eight five
there is infinite which is a little surprising
but that's not necessarily okay there's one point eight


little surprising to see infinite there but that's better than going 
the other way
i don't remember exactly what the expected readings are for qoyllur in 
particular

yeah if it would be greater than
two
then he won't she won't show us anything you know and maybe i was just 
wasn't pressing hard enough
if there was a little bit of solder flux residue on
the pin
then he can act like a varnish furnishings later

okay there
just deliberately
checking two pins that are connected together to make sure
that the beeper does work

i don't often see
shorts on the power
because they basically only happen if there's a problem with your 
soldering and
i'd like to think that i have enough experience now that my soldering 
is pretty good i don't usually make serious soldering errors anymore
after a few years of doing this sort of thing but it can happen to 
anyone and much better to catch it at this stage then
then when you get a puff of smoke at the very least that that smoker 
smells bad and its really bad for you so you shouldn't be inhaling it
okay
i
so that's all of those tested
and now i'm onto the
adjustment and testing
did this short circuit test
i
i'm going to need to let's see powered up
yeah

just refreshing my memory there is the procedure for these
so i'm going to use the other multi-meter because it happens to have 
the clippy leads on it
and i'm going to power up my lab power supply which is off screen to to 
the left there
that puts your req power into these connectors
i
and i'm gonna need an adapter to get the
clip leads on there too
work with the output
so this adapter is just to
a mini jack and patch cable
the idea bang i can plug that into the the jack output of a
filter into
and read the the voltage on here
now one little gotcha with my lab power supply its a cheap chinese one
and it just has it has a voltage range of like zero to thirty five 
volts or something like that
zero to twenty four i guess
and its just a single turn part for controlling the voltage so that 
means its very sensitive if you just bump it it goes off like point 
two of a wall
and also it it changes voltage slightly as it warms up
so if i wanted to be right on twelve point all
i have to keep an eye on the dial
and adjusted and ideally i adjusted without anything plugged in because 
i don't want to be feeding random voltages to mia
to my module under test
but its usually not a big deal to get it too
hit desired voltage
red stripe down standard to your rare practice there this module as i 
just verified with my beep test it does have functioning reverse 
voltage protection diodes but much better not to depend on those

so



i'm going to aim for zero volts here


little unexpected maya
i screwdriver that i wanted to use for that is evidently a little too 
big
so i'm gonna have to find a smaller
here we go
yeah this one is i think just a little smaller

and i can just dynamite into one
close to zero

this offset voltage is very temperature sensitive and its subject to
one over f noise which means that it sir
it drifts over time
even apart from the temp the the voltage thing so i just try to get it 
even within a tenth of a volt which it is right now and you see its 
drifting up and down and all over the place

just the other one




in these interact so i have to go back and do the first one again and 
so on



















there we go
were there
point on there
that's a good to good result


the power supply is down to eleven point nine again so with it 
unplugged i'm gonna
poke at the dial a bit more
back up to twelve point one

ten point seven five


one of the reasons that
those are ellen thirteen seven hundred mod chips are no longer popular 
and that contributes to their being discontinued is that they are 
subject to this
dc offset business
they require a fair bit of trimming to get to get good results and
understandable that a lot of designers nowadays don't really want to 
have to go through that




i mean really all of analog is so
odd doctor scandalous says all right i'll bite what is a coilover v cf 
this is a module for a
a eurorack modular synthesizer so i
a conventional analog synthesizer will have different parts to it all 
in one all in one box
but if you want a greater degree of control over your music
you can go the modular route where you buy separate modules for all of 
the different parts of an analog synthesizer the way i think of it is 
that its like if you have an acoustic and musical instrument like a 
saxophone
do you have something to read that makes a noise and then that fits 
into the body which shapes that noise into a musical tone and you've 
got other parts the keys that are used for controlling controlling the 
pitch and actually the the player's own mouth is used for shaping like
articulation starting and stopping of notes
in a modular synthesizer each of those functions is performed by a 
different module sold the v cf is
a voltage controlled filter is used for shaping the timbre of the notes 
its somewhat like the body of the saxophone and then you would have 
other modules that you can put together
and patch them together with patch cables so here's here's the module
he will eventually have knobs put on these these shafts here
this this creates a tambor and what is special about this particular 
one what the qoyllur v cf in particular
is that all
it uses coils on the back of the module we have these these coils their 
inductors are a type of component that is not frequently used in audio 
circuits because of there's a lot that can go wrong with it
but that gives it a sort of a unique sound its a little different from 
any other vc up on the market so people who value having a unique sound 
in their synthesizer may want to buy one of these
i
and that's what that's what that is now i don't know if i actually saw 
doctor scandalous as a question in time for
for them to hear the answer but
it'll be on the year
it'll be on the
recording anyway





































there we go point o for there and minus point one seven their target is 
plus or minus point one

with all the knobs four o'clock counterclockwise except this cut off 
knob just a little bit above the bottom

there goes my power supply again


















it takes a sentence often several rounds of back and forth between the 
two adjustments because of the way they interact if one is way out then
one of the internal amps will be
hearing the the power supply rails on it sir
and then that prevents the other one from
having a normal response


so i have to go back and forth between the two
getting each one you know closer to where it should be
that looks pretty good on his point on there in minus point or two there















i think the reason that it continues to change is largely because of 
temperature drift
some of the components in here are quite sensitive and especially if 
they've been in
in the wrong voltage range
they may have been heated up and then once you get them closer to the
the right voltages they cool down again and so forth







like why did that suddenly jump from almost zero to about three









its even possible for there to be like magnetic effects
bearing in mind that we do have coils in here











okay so that one set
within range
try this

the idea is supposed to be that as each one gets closer to its right 
value it becomes easier to get the other one into that that one's right 
feeling also


hello meta views









okay that one's within range and
that one still isn't







henry and chair
an enraged there were done on that one






















to some extent i just sort of hit it and in a random direction and hope 
that it then lands about where i want and then try again
when there's so much interaction and so much random stuff going on
he can be hard to adjust them any more systematically than that






the
the
the
the
the
the spirit within range
this one
still its a bit more
the
the
the
the
the
the ok i'm going to do the thing
and swap the two
pimp chips and this one
the because that may give me better results
the
the two identical op amp chips
i
they may the individual chips may have different offset properties
so sometimes if there's a hard time getting it to work
to be adjusted with intolerance
ah it helps to swap them
the
the there are special tools who can get to make this job easier but i 
do it so infrequently it doesn't really seem worth the
the space in the toolbox for them for one of those
the especially in as much as the ones that are actually good for it
you need a separate special tool for each size
the fourteen pin and the sixteen pin the eighteen pin and so on
the
the go
the
the
the

okay so with the
but the op amp chips swapped
the have to redo this adjustment but it may turn out to be easier
the
the
the
the
the
the
the osama pando six okay that one's with
so yeah swapping the chips did work

alright so the
major can go off to the side
and then the next thing to do is add the the knobs i guess
the first
tighten all the
panel
hardware
that and the big one though
half inch wrench
if you're gonna work on electronic panels you end up
needing both enchant
millimeter sizes

but it is kind of a nice feeling because i'm doing this on a pro scale 
with the you know building the same
devices repeatedly
i can afford and it makes sense to actually buy a specific wrench for 
each task
so i have enough these half inch ones that i have to tighten them 
that's okay i got the half inch wrench specifically for that instead of
needing to shell out for a whole set or
or trying to use some kind of adjustable one



















so these are basically done i am going to want to probably before i 
sell it to plug each one into iraq and actually listen to feeding 
signals through it make sure it sounds ok
but because i will be doing that for sure before i sell each one 
there's probably not much point needing to do it now given that i'm
pretty sure they electrical work
the kinds of problems they can shelter in assembly would usually have 
caused one of the tests i ran earlier to fail
so given that i didn't get any any unexpected jeeps or unusual voltage 
ratings from that to diode test and
i was eventually able to tune in to
zero voltages on those offsets and so on that's pretty good indication 
that the module is not completely screwed up
so i'm going to be counting out the other little goodies that go with 
the module
when my customers buy an assembled module like this
it comes in a nice little box and they get a little goody bag that has 
a sticker and some mounting hardware
and they also get a rubber ducky

something else i will have to do but i think i'll do off stream is fill 
in a serial number on each of these
my serial numbers have four digits for unlike the actual serial number 
that starts at one and goes on up to them in the modules i make
but then they've also got a four digit suffix that is randomly chosen 
that way if somebody has a problem with the module i can ask them okay 
what's the serial number on the module
and at last the four digit suffix is kind of like a pen write it it 
lets me know that the module is really one of mine that i made
because i do sell these them as kits as well and i
and i publish all the designs so someone could sit down and to make 
their own and sell it and that will be fine except that i don't want to 
be stuck doing customer support on somebody else's problem
alright
so i guess next it'll be knobs

he's already assembled modules so they get the green arms
one big one for each module
and two little ones



huh







its an



















there's different ways that knobs can fit onto the shafts and these 
ones i'm using are a thousand with a little setscrew
onto smooth the shafts which means i can put them at any angle i want
but it also means that when i'm strolling around i have to carefully 
get it to just the right angle its not like one of the d knobs where 
it will do
it would only go on at one angle
if i were making these in a bigger factory with the
you know larger volumes and people other than me making them
then it might make sense to
use one of the other fastening methods that's more goof proof but doing 
that within
it might cost more because i'd need to get the
the pots with their shafts at the right angle and so forth to all match 
up
like on on these modules the
the three parts behind the panel are all
mounted at different angles
so if they were d obs they couldn't all take the same knob at least not 
if it has a marker line like these ones do
i would have to either get three different kinds of parts or redesign 
the circuit board to put them all at the same angle
or get three different kinds of knobs
you know it would be a lot to pay just for the convenience of not 
needing to adjust the angle by hand






























hello to elo undefined bh vr
behavior
maybe undefined behavior






























alright that's knobs are six
of these
so make a note of that


and now its time for some goody bags
ah
everybody who gets one of these modules
is due to receive let's see if i can find the right bags here
yeah i'm going to use these recycled or reused bags
they're a little bit less fancy than the brand new ones
but
i like to think that my customers want to be environmental
so
reused bags

and in each bag
it'll be one too
six a sticker




i have an extra

so let's say they get a sticker and four screws and four nylon washers














i bought the stickers from an outfit called sticker mule
and
part of how they promote their business is that when you buy a badge 
stickers
they ship you guess what a sticker that says sticker meal but they also 
ship you
as a promotional goodie they ship you like environment a little
circular chunk of them
cardboard
so you can put under your drink so that condensation won't make a 
puddle on the table
and i was using these sticker mule bar maps probably longer than i 
should have because they eventually started to started to grow mold and 
fall apart
so i suppose sticker mule
he's pleased to have that happen because of it kind of is telling me 
okay time to buy some more stickers from them
but in fact i think i'm actually going to have to get some other posters
that can be either more permanent torah
or or just replaced frequently

so for these m three machine screws and
in each goodie bag





but wait there's more
because we also get for these nylon washers the idea is when you put 
this into your rack you use the four screws through these holes to hold 
it in the rack but people
especially if they're going to sell resell the module after using it 
for awhile people don't like to have what they call rare rash which if 
you if you just drive a screw through that hole tightly it'll disturb 
the aluminum a little bit
so given that i'm selling a premium product i want to go the extra mile
i provide these
nylon washers as well so if you're going to be careful about rock crash 
you put the nylon washer on and then you drive the screw through it
and that way you won't disturb your panel it'll remain pristine
and then you can hope that you'll get a better resale value for the 
module and the used market











i dunno it would be interesting to find out but it might be very hard 
to survey this how many of my customers actually use the
nylon washers
there are going to be some who don't even use the screws i provide 
because these are standard in three screws which is your rack standard 
but
some people make racks that they call euro wreck that are like m two 
point five screws so it needs totally different screws and some even 
use like a us number four screw which is only roughly the same size
and then even customers who actually have a standard euro wrap it takes 
them three screws somewhat like a special screw
either for looks like you can get them in different colors
or people who think they're going to want to take modules in and out 
very often
they would they will get like a wingnut type screw head or a near old 
screw head
so that they can
insurgent remove screws without them
without meeting a screwdriver
so that gets back to the whole modular synth thing of customizability 
right i provide the kind of screws that i think should be the default
but
its understood that people may want to substitute something else





alright what else do we need we need power cables
now which kind do these take
to me like this ideally takes a left handed power cable
so do i have
enough left handed i think i do i'm a little low on righties but
here are five
don't know i do not have
six lefty power cables
so i guess
now would be a good time to make some more

really i probably ought to make twenty
lefty and twenty righty
geez and maybe also some sixteen pins
okay twenty of each i guess it'll be
huh
i was missing this earlier
glad to have found it


sup i am going to
briefly put up the filler animation
well i
use the restroom and get out the stuff that i will need for
the making power cables
so you should probably give me about two minutes here and then we'll be 
back with power cable making

and
i
at the
the
the
the
the
the
the
the
the
alrighty i went a little longer than i expected because i had a hard 
time finding my cable tester i didn't realize it was already on the 
workbench but here's the cable tester
you sat in a few minutes
i also then i wanted to let the piece of music play through
given that i was near the end of it anyway
that that piece of music there is one of one of my own compositions
any way
i
i don't know actually let's see i was just thinking i would make twenty 
lefty twenty righty and twenty of the sixteen
pin cables so that would be forty and forty eighty that would use one 
hundred of these
i dc connectors
i don't know if i really have that many
in fact at the moment i only immediately need one
i came off but to let's see how
how are doing you know i don't have one hundred of these connectors or 
how many do i really have
three six nine twelve thirteen fourteen fifteen
fifteen
thirty forty five sixty sixty five
so i guess i can comfortably make half as many as i'd planned ten lefty 
ten righty
that'll take forty fifty
yeah in turn ten left eaten ready in ten sixteen pin
so
actually i guess i should cut the cable first



i invested in a nice cable cutter here
because the the less fancy one just wasn't wasn't cutting it so to speak
oh and i'm going to run out of cable in this
package too but that's okay i've got plenty more more cable

so after some experiment i think that the
the optimal length for the cable
is what i get by doing
a nine inch piece of the the cable per se now the actual cable assembly 
ends up shorter than that
because there's some that gets used up in the terminations

true


three

four

five


six

seven

h

nine

ten

eleven
twelve
thirteen
fourteen
fifteenth

sixteen

seventeen
eighteen
nineteen
twenty so that should be all of these small tin pin cables
five

ten

fifteen
twenty yup

and then i need to cut ten pieces of the the wider the sixteen pin cable


sixteen pennies for them
middle path vizio and the the new module the gracious host

because those are the modules that either have fun
bus access or five four requirements or both
they need access to the other pins on your iraq bus
three

four

five
six
seven
eight

nine
ten


so that cable goes up there
and
five
ten

was ready to go
i
okay
so next i guess i do have to walk
hang on
its actually the sixteen kind ones that are in the crunch
yeah
do i even have enough for this man let's see here
so sick ever so the ten pin cables each need a sixteen pin connector on 
one end and the sixteen pin cables need a sixteen pin connector at both 
ends so ten sixteen pin cables i need twenty there and then twenties 
ten pin i need another twenty and i need forty of these three
nine ten eleven
eleven twenty two thirty three forty four i'm good
but i won't have a lot extra

five

ten
fifteen

twenty
twenty five
thirty

thirty five
forty yeah this is another item on which i'm
running low and will have to stock up in the middle of the supply chain 
nonsense
that's a prices constantly going up and that's a bad scene but
what can you do
so i
i'll do these first cause they're simpler



goes on at first just with hand pressure
its not really letting the connector bite through the insulation i'm 
just pressing it into place this way i can get the alignment right
before i really commit with the
squeezy tool


its important installing these to get the
alignment pig on here
the alignment key lined up properly with the
the stripe on the cable because
if you build a
if they don't go on in the proper orientation of one end and they're 
correct on the other then you end up with a bit a really bad cable that 
will fuck flip the
power around
and its also possible to build one that will work but that has the 
stripe on the wrong side
the fact is much as we would like to
disbelieve this the electricity doesn't care what color wire comes 
through
so
if you build one with the stripe on the wrong side you'll confuse the 
user
and you may lead them into making mistakes


i had a spam just the other day from a chinese company that they were 
trying a little harder than these chinese companies usually do because 
they had actually read my website and they knew what product i was 
making
and they wanted to offer me the service of making these cables for me
but
although making cables is a little annoying
its not so annoying that i would want to pay someone else to do it
when i could be earning the money myself
and also i would have a hard time trusting anyone else to actually do 
it right and not ship especially given my previous experience with
some of these chinese manufacturers where the issue is quality quality 
quality i actually had to fill out a
a
oh i didn't have to but i do to fill out a survey for alibaba which is 
the the higher end pro version of ali express right
ah and they asked what's what issues exist for you
and the the answer is quality quality quality every time with the 
exception of circuit board manufacturing which seems to
be pretty much a solved problem though but every time i've tried to get 
something custom made
empire chinese factory
i have had trouble with the quality
and as a result i basically just don't do that anymore
because its not worth it
you know the
front panels on my modules i'm now dealing with a company that's
head office in ireland and manufacturing in germany and
on the surface they charge a lot more than
the chinese company i tried to deal with but
the other side of it is that i know the panels will actually be ones 
that i can use or on that one occasion when they ship me some that i 
couldn't use they made good on it and didn't give me a hard time about 
it and
overall it just makes more business sense to deal with them
because i can't afford the lower price from the chinese factory if i'm 
going to be
having to deal with the the quality problems that that i did have to 
deal with last time i tried


its not a bourbon if you can't use it right


okay
so now i can press all of these





i guess it makes sense to do all the sixteen pins first
actually i think i will
i was just thinking about at what point do i want to stop and do the
electrical tests on them but i think i will actually make all my 
kittens for us to make
warm up the tester
literally because
its a pretty simple dot
resistor network that
its not quite
yeah
that one went on at a slight angle and it may end up failing the test 
we'll see if it passes it'll be okay
yeah the the testarossa
device i built myself that is electrically very simple and it wastes a 
certain amount of power so it does warm it get it gets pretty warm when 
its running





retaining clips
or actually i guess they're strain relief clips


there we go that's a finished sixteen pin cable assembly
and unlike the tenant sixteen ones
these these don't have left and right there's only the one kind







the
the
the
the
the
the
the so these are in principle ton but they still need to be
tested
and now on the
the ten pin ones i wanna make
ten with the cable with the sixteen pin thing on one end and ten with 
it at the other
the nuts one
the two
the three
the four
the five
the six
the seven
the eight
the nine
the ten
and then the remaining ten it goes at the other end
the eleventh
the twelve
the thirteen
the fourteen
the fifteen
the sixteen
the seventeen
the eighteen
the team
the twenty
so these will get crushed too
the
the


and the other ones
the
the

the
the okay i think before i put the retaining clips or the sara them
strain relief clips on there
i'm gonna do the other
the other side but thea
these bulls

can i need twenty of the song
five

ten
fifteen
twenty
the
the
the trying to keep them together summer






the
the
the
the
that's all the cables have
one handedness
and so next its the other
the
hello pitch who says getting big shout outs on the modular in a week 
discord channel
oh that's good to hear
i hope
the
the
the
the
the
the alright all the connectors in place time to print them
the


just complimenting the documentation and kick quality
well that is good
the

the
the hulk
a
i
the stream really clips
for all these
the
the
the
the
the
the
the
the
the
okay
i know the other the clips
its you know
each of the steps in making these is pretty simple there are a lot of 
little steps
i think most people when they look at her
power cable don't quite realize
how much goes into it
and of course if you're getting them
for the larger supplier you're quite likely dealing with the cables 
that were made by a robot because there are robotic machines where you 
could just sort of feed
for your great big spool of wire in one entered to
i guess a tray of the year
connectors and it'll just do everything internally
its i think a few tens of thousands of dollars for one of those 
machines which considering how many different manipulations that has to 
do is actually a pretty good deal
but i don't make enough cables for it to be worth doing that






















okay
so that's thirty cables
made but not tested and the next step is to test them
the handy dandy cable tester






i dunno how visible this will be on the camera it doesn't do well with 
the
bright lights but what i'm getting is three green lights there are five 
green lights
which is appropriate for a good
ten pin cable

hmm


you're sixteen pin

yep in all eight lights go green







surface on the camera
go






















this is one of the sixteen pins here and so far no problems
i kind of hope then i will see a band wouldn't because it would be 
interesting to
know that the
tester really works although i have tested the tester
extensively










kind of here's one of the ones of the opposite handedness




















i suppose i ought to write a weblog entry about this tester it would be
a relatively easy way to get some content and there are probably
probably people who would like to be able to build one for themselves 
but i don't really want to like make it a kid or something



if i can keep it to be just a weblog entry and not have more fancy 
published project that's probably about the right level






okay
arm
just for kicks
just a demo this chester i'm going to take one of these some jumpers
and put it across two pins of the
there
and then if i
if i hook up the cable
actually
yeah if i hook up the cable
one of the lights goes red instead of green
that indicates a short between adjacent pins
so that's the point of the tester if there's a if there's a problem 
with the cable such that too
adjacent pins etc
are shorted then it'll it'll go like it'll go go red
anything more than the picture and schematic is just extra reason 
really yeah yeah that's about the level i would put the data
picture and schematic and some text describing it as having some text 
description is important for ezio and i hate that that is the world we 
live in but it is you know that's why your recipe websites never are 
just a recipe anymore they always have to have
the description of the when the author first encountered this recipe or 
whatever but there is something to be said for having a description 
that will contain the keywords that will hit the the that the search 
engine will return
okay i
with those cables made i don't have a lot more that i really need to do 
right now
so i think that i'm going to and i am at about the right length so i 
think that i am going to call the stream here
thank you for tuning in i hope you enjoyed and anyone who's watching 
this either now or on the recording if you haven't already followed me 
on twitch it would be nice if you would wear out i think forty six now 
and that's just four more to hit fifty which is the next level
i
and there we have it have a nice day
yeah hm
yeah hm
