i
good afternoon welcome to my scheduled stream for era
september thirteenth
in this stream i'm going to be working on the qoyllur v cf
i'm a little low on stock for those
so i'm going can build a half dozen more
now twitch has a new thing that they call goals and
they sent me an email and then went to a landing page you know how that 
works and
the idea is its supposed to be able to show a little bar or longer
overlaid on your stream seeing how many in my case subscribers i have 
and how many i want ahead and that seemed like a pretty neat idea 
because i am getting close to the fifty subscriber mark at which point 
various exciting things happen so i
went through the little process and i set up a goal and that was fine 
and then i realized oh in order to actually make this work it did there 
was no documentation of how to actually do it i there was a a video 
which i did not watch because i never watch tutorial videos that there 
are stupid waited substitute
for documentation are so i sort of managed to figure out that the idea 
was that you set up the browser display like obey obvious has a feature 
for displaying a web page as a video source so they give you where you 
twitch gives you a you
your owl and you point your ob es browser at that and then i went to 
configure such a source in my ob es configuration oh and there was 
there was actually a link for written documentation but it went to some 
weird commercial thing it was no bs even though it said it was obey us 
anyway i found that i
myopia does not actually have the browser feature so further research 
it turns out that you only get that if you compile all bs using chrome
i'm not going to run chrome so that was the end of that so we don't get 
a little bar on the screen unless i manually create software to do that 
which is probably not worth it but for what its worth we are currently 
at forty four followers and i'm hoping to get six more
i
and hello ivy a f
twitches streaming control things still says that i have no viewers 
tuned in but
i don't trust that either really there's a whole lot about twitch that 
is not trustworthy
but let's kind of get started here i have my
bill of materials here and i'm going to be making six of these so i've 
got two four six sets of bins here
and i'm going to get right stuck into counting out parts for them
two boards in the corridor v cf i am down actually a stock of two 
assembled coil or vcs here i've been holding off on making more because 
of needing to resolve the transistor situation that has been an ongoing 
saga through the last several weeks
have fun
of my stream but it is now basically resolved i have a stock of 
transistors in place
and i don't know if i mentioned this last week i think i probably did 
but the on
the gracious hosts my next module
ah there's also a supply issue for that because it uses these specific 
microcontroller chips from microchip corporation and
they mouse are both ran out of stock
so i ordered
the forty that mouser said they had in stock they shipped me thirty two
and microchip says that they will next be restocking
each day i checked it said they would restock one year after the day 
before i the day i checked so on september first it said that they 
would restock on august thirty first of twenty twenty two and on 
september second it said september first of two thousand and twenty two
i have not checked in the last few days but i'm guessing that if i 
checked today it would say september twelfth of two thousand twenty two
the bottom line being on not at all sure that there will ever be any 
more of those chips made so i have thirty two and its quite possible 
that i will never be able to sell more than thirty two gracious hosts 
in which case it'll certainly be hard to cover the fairly substantial 
development costs of that project
but what you're going to do i mean the development costs are now spent 
so if i want to make that money back at all i do have to sell as many 
as i can of these
of these modules so that is the plan for that but today i don't have to 
think to owen's that today i don't have to think too hard about it
it really kind of killed my motivation for actually finishing the 
development so although there is something though i have to do i mean i 
i'm
like that close to having the file system co-working
at the moment it can actually traverse the file allocation table
on a dos format the usb stick
and the good side of this is that that's really quite an achievement i 
mean i have this chip that i am programming it in assembly language and 
there is no support for talking to the usb hardware from assembly 
language the microchip corporation wants you to use their c language 
driver
and that doesn't work for me because c is too high level which honestly 
for this project
and
so there was a certain amount of reverse engineering involved in 
actually writing a driver that would work and the usb driver that i've 
written does in fact work
and that that's a thrill knowing that i'm able to actually do that
but
having a low level usb driver is only the start of the fun because i 
also need to have a dos file system that works and
the i in it needs to work with fat thirty two on a sixteen bit 
microcontroller
so there's a lot that can go wrong with trying to do thirty two bit 
arithmetic on a sixteen bit microcontroller i had to learn among other 
things a lot more than i ever really wanted to learn about long division
i mean you know who who actually understands long division
most people sort of learned in school and then forget it
i went to a montessori school where the montessori mathematics 
curriculum for young children is actually really good i i think its a 
very good way of learning math but at least at the place i went they 
did not do a good job with long division in particular
i ended up having to learn it again from my mom a couple of years later
but even so the
the basic long division
algorithm that everybody is expected to learn in school
it doesn't work all that well when you try to implemented in assembly 
language on a microcontroller
so i had to learn a fair bit more about
about long division in order to be able to put it into a framework that 
would work with a microcontroller
anyway
i guess i'm just sort of making excuses for the fact that my current 
fat thirty two driver
miscalculates where to look for each cluster when the clusters go 
beyond the sixteen bit limit
and i've really been putting off trying to
trying to fix that i've been doing a lot of other things including 
playing dwarf fortress a fair bit in the last few days
i was watching area silva traces
stream she's playing factorio
ah
and it didn't make me want to go download factorio but it did kind of 
make me want to get back into playing dwarf fortress
so that was part of the origin of that
unfortunately the latest version of dwarf fortress first of all it 
seems like the
hello pitch it seems like the makers of dwarf fortress have kind of 
finally succumbed to the disease of
wanting caf graphics and all of their latest development updates refer 
to things that are going on with like some kind of new graphical edition
yeah
what i think of as real dwarf fortress that i'm playing hasn't updated 
since january
and the version that's came out in january is not really stable i've 
been facing a lot of them
a lot of seg faults
so
so i've got it set to save the game every season
and its just the fact that sometimes the dungeon collapses and i have 
to roll back to the last save
and that's not what i what i'm accustomed to playing that game
but there are features
that are new that i actually like and its one reason i'm talking about 
or fortress here is to kind of test the waters for whether any of you 
would want to watch me actually playing it on stream
i
there are features that i like in particular
i don't know how new this is but it seems like the
handling of dwarves injustice is a lot more interesting now that when 
there's a crime you can actually go in and do a real investigation and 
question suspects and some of the suspect lie and he can gradually sort 
of put together a picture of what was going on crimes also
can are a fair bit more complicated now like i've had a couple of 
conspiracies and my fortress already and that was never a thing that 
existed in earlier versions
so i i actually got quite interested in okay keeping track of what are 
the personality traits of the captain of the guard and how does that 
affect the results she gets interrupt when investigating crimes and 
what sort of crimes are happening
what
what's going on in the world outside my fortress that leads these 
conspiracies to exists and so forth and so on and all that is due in 
this latest version
page says similar to the new total war games i guess so i don't really 
know anything about those but
so that partly compensates for the loss of stability
in this current version but
it does sort of concern me that
that the development effort seems to be focused now on the graphical 
version and not
not the text based graphics one



i'm counting out for two
two boards at once here so i've got the upper row of boxes is for the
for and the lower low is for bored ones so i have to keep switching back
and forth here




i was actually thinking that depending on how long the respective 
streams went i might try to do a raid on
area is strange because she was
streaming just as i was getting ready to start this one but when i went 
on twitter to post the announcements i saw that she'd had internet 
troubles
as is not unusual and had to end the stream in a few minutes ago so 
that will probably be happening but de culture
was also online
so if de culture is
still active we can do a raid
on him
i think the culture is a boy am not quite certain
never really clear with these people who use aliases
if they don't say

the culture is doing skirt this schoolgirl a month
ottawa
all month this month



when i design my jewels like quite often sort of go for circuits that i 
think are cool
and that's part of the origin of having just a single one of these 
switching diodes in each qoyllur because i'm using a single diode full 
wave rectifier
and its not at all obvious that its possible to create a single diode 
full wave rectifier so
ah
doing something that feels like almost like getting away with something 
i mean i diode costs like a one and a half cents so you're not really 
saving money by doing that but its a cool trick
normally you would need to at least
one for each direction





anyway in my current dwarf fortress game
i embarked on a glacier
so it was just you know flat ice in all directions
and
had to dig down to the caves in order to get water
because in the short term your fortress doesn't really need water
but you certainly need alcohol
and for that you need dirt
and there's no dirt on a glacier
so you have to get to the caves either to to grow things in the dirt 
that occurs in the caves or to get water so that you can irrigate near 
the surface and that was the direction i opted for
because once you irrigate you can create mud and grow your
grow your dwarf mushrooms in that and then you can brew them to get 
wine and away you go
people sometimes attempt as a sort of a challenge they tried to do the 
the sober fortress
run your own fortress without letting the dwarfs drink any alcohol
but that is only borderline possible
and i figure if i'm on on a glacier already
that's plenty challenging enough
okay now i'm onto hardware here not stand off screws
i think i will do that rather than flipping to the other side and doing 
the inductors
screws
do i even need any yeah i do two screws
i've not been consistent in making these bills of materials as to 
whether i include stuff like mounting hardware
which would go out with the
the finished module but its not really exactly part of the module
but these coilovers do use
two screws that are actually part of the module
for holding on the panel
and i have the impression that some people have a really negative 
reaction to that they they really hate seeing the screw heads on the 
front panel on the module my point of view is that its a mark of 
quality it shows that you're not just depending on the parts and the 
the jack sock
to provide the mechanical support
but there are those who think that its somehow a sign of low build 
quality and those are often the same people who think that
they think that a pcb panel made of fiberglass
album quality
which i mean i guess its just a it comes down to you can't predict 
what or or control what people will think or know
but i think there is no question that panels want to be metal in 
anything that's not metal is a compromise for for panel quality




that's screws and nuts
and more into standoffs



where are the staff here there
two each of eleven and thirteen millimeter




niesr in the fancy bags just pull open


i'm going to arrange them into sets of four as i usually do
for better
better organization in the future












so these are in groups of twenty twenty and
this next group will be forty and so on










i think its supposed to be one hundred and each of these little bags 
will see if i actually get one hundred out of the bag i probably will 
these
standoffs usually seem to be
countered quite precisely
not every item that i buy is









actually i should fish this out of the garbage because i can use this 
for
storing the
countered and organized ones










okay got twenty forty sixty eighty one hundred
so i will pull out
twelve there
and put the rest
back in the bag






its true nature
the lower pins


really low on the thirteenth here
so that'll be another thing to get one smart money comes in

unfortunately cash is a little tight right now because of
having to buy advance those up
transistors and also the
microcontrollers that i wasn't planning on buying until later in the 
development cycle for the gracious host but
given that i realized you know and there might not be any more of those 
chips i had to buy all that were still available
as well as the other digital chips that go with them
the s rams and the
the ducks
alright next let's do coils

i'm gonna need some more of these crystals as well for those digital 
modules but
crystals are much easier to come by so i don't think there is critical
what have we here
probably fuses
alright

the coils are another critical thing which currently there's no
reason to think that they'd be in short supply but
i have to keep an eye on that
really if i can't get these exact coils i'm probably going to 
discontinue the the coil or because they're so critical to the sound i 
could substitute other coils with similar specs but if they're not 
identical then
it'll mean a change in the sound
which might not even be a bad thing but it would definitely be a 
different thing its the sort of thing where i don't want to tell the 
customers oh yes still
i would want to like give it a new model number or something

but there's no sense worrying about that one it hasn't happened and 
other things are happening
for the solve the problem with god i guess


japanese philosophical concepts are often oversold
it was a hilarious tweet that i re-tweeted about how
you know you have to understand that in japan arson is not considered a 
good thing and because of the philosophical concept of martin ten i
she just means don't burn
and so even though you may be tempted you should not set fire to 
buildings in japan
and
take off on that with the
whole grid of different inspirational books
that said like you know a roku the japanese art of walking and recruit 
just means walking and
you know presenting
very straightforward and ordinary concepts that are not unique to any 
particular culture as if they were a big deal and someone somehow 
special and unique just because you translate the name into japanese
and where was i going oh yeah yeah wabi-sabi so there is a somewhat 
more legitimately unique the japanese concept
of
the aesthetic of appreciating something
with the understanding that it will not be permanent
and i feel like there's some amount of that in
building vintage electronics
vintage vintage style let's say electronics that all of the components 
i'm using here are on were borrowed time
that they won't always be available
and
what am i even doing here
i need these
one in each bin
and so we have to enjoy
each of these designs
and
and the entire style of electronic design
well its possible because it won't always be
i can be carriage a little too far
but
but it is a fact
nothing i do here will always be the same way in the future

and with the the ongoing
speed advancements a lot of things
its actually amazing that some of this stuff has lasted as long as it 
has been the op amp chips i'm using today are not exactly the ones that 
existed in the nineteen sixties but rpm for chips did
and
someone from the nineteen sixties would be able to look at a modern one 
and say okay i know what that is this is just a slightly newer and 
fancier version of
the chips i was using
and now if you compare against let's say the the duration of courses as 
a means of transportation
the duration of through-hole op amp chips is a lot shorter than that 
but its longer than my lifetime anyway






wrong bin
where's the right point
it is
i need to go through and update some of my bin labels

because as time goes by the
organization system that i said i want set out at one point may not 
always be
the best one okay so these are the ss eighty five fifty db i did not 
actually build a separate prototype for the
for the coilovers to test these because i'm quite sure
that they will really work especially given the checking i did with the
with the coil it was not quite the leapfrog the leapfrog was the one 
the one where i was most concerned about them
but here are a couple that are used in the exponential current source
and its not even really necessary for an exponential current source in 
the qoyllur to be all that great because it doesn't attempt to be 
highly accurate and tracking
so its only partially temperature compensated and that's good enough 
and it'll still be good enough with new transistors i'm quite sure
alright onto the resistors















not quite as careful labeling on these because
i am building it myself i just need it to be good enough that i can 
remind myself which one i'm looking at
and not have to squint at the color codes

i think i mentioned i watched someone build one of these on a stream or 
actually it was a leapfrog
and the fellow never use the color codes at all he would either look at 
the labels or
or haul out the alma mater
i dunno its none of my business maybe he's color blind but i was a 
little surprised
because now granted not everyone memorizes the color codes but
i one does if one builds electronics in any significant degree you 
memorize it by accident even if you don't try
so that's certainly the approach i remember i would recommend is ok you
makeup a cheat sheet to list of the the codes and then
i use it as much as you want and pretty quickly you find you don't need 
it anymore



three of these one case per billion lower bins
six

i mentioned the montessori mathematics and
at least at like the lower elementary school level which was the only 
place i
i was exposed to it one of the things they're very big on is counting 
by k okay count from
zero to eighteen by threes as i just do and that is actually useful
and then you compare it to what they teach our granted i don't even 
really know what they teach seven year olds and more conventional 
school systems but
come by however many
is a really practical and effective thing
and it leads into stuff like multiplication and
so on








one point eight is next

huh



















there are a fair bit of relatively low value resistors and
in the qoyllur and i think what it comes down to as far as how that 
came about i mean i designed the thing so i know why each individual
resistor values used but why i ended up using so many small ones
i think the general pattern is because the puts a fair bit of current 
through those inductors i mean a safe a fair bit of current its small 
a tiny fraction of the power rating of what they could handle but up
its more current than i would usually use
in in the signal carrying parts of an audio circuit
because i'm trying to push the inductors into a range where they'll 
start to sound like inductors and have a distinct behavior from
from other components
so
if its pushing like
one hundred micrograms instead of ten micrograms through a given 
component that leads to resistance is there in the few kilometres 
instead a few tens of kilometres






there are other factors to the five ten
ohm resistors in particular that i started out with
those come about because of trying to scale down the voltages of the 
inputs of the ot eight chips
i
because oh thx end up having usually a fair bit more voltage gain than 
you really wanted so
huh and you have to kind of kill the signal before it goes through 
there and that is part of the reason that there tends to be
a fair bit of noise and no th circuit like this one
cause you're you're dropping the signal down and it gets not into the 
noise noise floor but closer than normally would be comfortable before 
you let the o t a amp it up again

and that's another way in which some of my designs are old fashioned in 
spirit even if i did all the design work in a twenty first century 
because
a lot of people say oh th are too annoying we shouldn't use them 
anymore we should use
i guess at twenty one sixty four or the equivalent
which really is basically just another roti eight but its wrapped up 
more nicely and there's fewer weird things exposed on the outside that 
you have to deal with in design
alright to each of these nine point ones

















they should have been in the upper bones







it doesn't make things somewhat fair bit more confusing when i try to
count parts for more than one
i set up at a time
i
doing the two boards for one module at once is not so bad but
after last time i tried i think i'm not anymore going to want to do 
more than one completely different module in the same run at least not 
when i'm also stream because that certainly takes
takes away from my attention as well


if you look closely you can see that i've now added the warning to all 
of my bills materials this is table is not a substitute for the text 
instructions
and i went through a whole big thing of
given that i hadn't realized but apparently its true and it makes some 
sense that there are people who try to just work from the bill of 
materials and not from the texts instructions partly because with many 
kits the bomb is all you get
so they get used to doing that and
then looking at my kit which really has a lot of text instructions that 
can seem kind of intimidating and then say oh well i know what i'm 
doing i want to
won't use the resources that i was given
but it will cause trouble i mean
you go down this list one hundred k i tried to install one hundred k 
for our twenty find our twenty it doesn't have the proper footprint for 
a hundred k resistor because its not one hundred recent k resistor 
its a horizontal single turn pot
so not even reading the words in the table let alone the words in the 
the book

so it occurred to me while should i just not have a bill of materials 
because you don't need it
i
or should i just ignore the issue and let people
let people make their own mistakes and figure if i get paid for the kit 
then its none of my business whether they know what they're doing when 
they install it or
eventually the the compromise i settled on was i include the bomb but i 
have a note this table is not a substitute for the text instructions 
and there will be people who will ignore that but then
its not really not my fault if i warned them

came next
going from one from here the eighteen k





alright here is a
bag to recycle and reuse it never ends right i went through the whole 
big thing and off screen to the right i i have
reclaimed bags that
have had the
labels pulled off and
in some cases solvent to solvent soaked to remove the glue





















alright now onto this one
twenty two k
yeah
morgan


















okay
twenty seven is next

i mean i guess i myself am working from the from obama here but only 
for counting out the parts which is really what its intended for
should be able to go through
a kid whether its an actual kit that you buy or quasi kits and 
preparing here for myself
you should be able to go through one of those and check that all the 
parts match the list
and that's what the list is for
but i'm not counting these out in the order that i will use them














thirty six













one of the reasons for using the thirty six value is that it goes 
nicely with eighteen
eighteen and thirty two or
exactly and the one ratio and
there aren't all that many parents like that among a standard resistor 
values there are a bunch of near misses
but in the full wave rectifier in particular its nice to have a pair 
that to the to within precision is exactly a twenty one ratio

like many people i'm using
resistors that are in the value series that goes with five percent but 
using them at one percent tolerance
so
there's a different value series that only partly overlaps
that is theoretically the standard value series for one percent 
resistors but its more different values than you really need
so i'm basically just using one person says higher quality five percent 
resistors
that's another way these nostalgic things although i mean few people 
would say that things were better in the day when you could only get 
ten percent resistors but
things were simpler anyway
even if that wasn't better
so i guess that's a thing i would like to embrace those modern 
improvements that really are improvements
but switching to the the official one percent value series and having 
to suck
i guess five times as many different values of everything and so on 
that would not really be a good thing
















okay
next on this list is the panel pots which i think i'm going to skip 
over as with the lumberjacks
and then we're and i can do the
the chimp trimmer prompts them
you have heard me complain about beef beef about it before that people 
say trimmer pots when they mean a panel pot with a
with a plastic shaft i dunno why they think that's a trimmer pots but
this afternoon i'm putting in actual trip pots which are a different 
thing

and there are exactly five of them in this
this is israel
sancho ninety seven war
and if they don't match color wise i'm probably going to
reserve the odd one out for later
cause i'd kinda like to ship a customer
trump hops that match yeah okay they don't match so
i'm going to take four out of here and eight over here and save the one 
before something like a prototype where it doesn't matter that it 
doesn't match

just to confirm these are hundred k horizontal one turn
four
six
eight


the blue ones and the green ones are equally good they're just 
different brands
so in the interest of not chipping someone
coil or where the two parts don't match
i'll save that one of the older brand for
some other purpose
when i just have one one need one of them in the module or if it says i 
say a prototype where i don't care that they don't match or whatever



alright now we're onto the big bucks at work
one hundred kv sisters
told the story many times of how i
ordered one thousand of these and got five thousand five hundred
so i need to in the upper bin and five in the lower bin
for a total of seven per

per qoyllur






so i'm down to my last pair of pants and that's trousers for you 
europeans
and
things are still pretty fucked up here so i wasn't really eager to
try to go shopping for more in person
so i decided that for the first time in a long time i want to try to 
buy pants online
i know my size and
i had a hell of a time
just dealing with the modern web
like i
i went to one retailers shop
and i did a search and of course it its as bad as most are parametric 
search rates you there's a field for size and is that inches or is it 
centimeters or is it an arbitrary size number well they have different 
items in their database that are cattle
all raised in each of those ways so if you type thirty six
yeah
it'll match some things that are thirty six inches
and other things that are way too small because it was matching 
centimeters
and other things that actually are the right size but won't match at 
all because they're sized in some other system
anyway
i and of course the the ordering of search results is going to be 
featured items first and reset to that every time you reload the page i 
dunno why
anybody thinks that we want to see featured items but i guess they get 
that from imitating amazon so what i would do would be that i would
putting a fairly broad search that would hit everything that could 
possibly be a pair of pants that would fit me then scroll through the 
list and open each one in a tab that looked like it might be a match 
and then i would go through after and close all the tabs that were 
obviously wrong
i
but
on one of the sites i went to
they were doing clever things to try to prevent you from browsing in 
tabs so every time i would switch to a new tab it would say oh it would 
pop up have met dialog box saying some of the information on this page 
has changed and then asked me to click ok
and it would do this every single time i track i switched between camps
and then other insults like it would have a list of sizes on the page 
some of them grade out because they don't have that size but ok the 
size i wanted is not grayed out so i should be able to put it in the 
cart and buy it
and but then at you know after i've gone through all this and click ok 
several times per tab because i was switching between them then finally 
when i go to click
item in the cart then it says oh this item is sold out
what's the point of having that whole graying out logic if its not 
even telling the truth right if its going to say sold out afterwards
so it made me feel a little bit better about my own
online store because
its certainly not perfect and i'm very conscious of the ways in which 
its not perfect
especially like there are some stupid things to do with how multiple 
currencies are handled which i'm sure drew cost me sales because there 
are times when my online store will just sort of randomly switch the 
currency on you
and i do everything i can to prevent it from doing that but there are 
limits because i i don't i'm not really the person in charge of that 
code
and its all fucking javascript anyway
i
but it made me feel better using these other other storefronts that are 
run by people who
are big businesses with real i t departments have their own and people 
who are as good at writing fucking javascript as anyone reasonably can 
be
and just seeing how bad their system still are
and and you know their customers tolerate them
since two seventy i want to twenty

two twenty


and i think its true in each pin each of the twelve bins for each 
twelve
sixteen twenty twenty four



















okay that's all the resistors
just to put these in the bins


i
not going to put the actual to post season yet
but i need the sockets for them


laughs

hi
fourteen pin

sixteen pin


















it occurs to me that my next scheduled stream is going to be on the day 
of the canadian federal election
it doesn't necessarily actually have any significant effect on the 
stream because
the election festivities will really be happening later in the evening 
as the polls close
but
this is just a sign of the times
alright so that's all the parts except the couple of power components 
that i'm working for later and pcbs
so pcb is coming next


these are some of the ones from i'm from india




the silkscreen came up pretty well on this particular batch
no smudges
you can tell that its lower resolution though than the ones i used to 
get from china

also these have the defect that i mentioned that where there's a line 
that would cross over the edge its missing
one of the interesting features of this module is that the two boards 
normally i design every board to be full height but in this case the 
two boards are different heights
and i noticed that i just now that i have switched these boards 
backwards but that's okay i can swap them
it just happens that this board has to be the height of use to fit all 
the components the the panel components on it the distance the person 
they need to be but there's not actually all that much circuitry in the 
qoyllur so i was able to shrink the the backboard a little
that may make it slightly cheaper to manufacture
because its less board space where you basically pay by the square 
centimeter
although the difference really is marginal

it does give the finished module any interest in interesting book 
having a little gap there
that the
the backboard doesn't quite to
go to the full height of the the franklin
alright
now for twenty four twenties a couple of minutes after actually
i guess i can get right into starting to stuff the sports i'm not sure 
that i'm really going to wine and one solder them today but
maybe if i put in the do the board stuffing that one lie that won't 
come up to about the right length amount of time i want to
spent streaming today
so having spent all that time to put points into the banner i just dump 
american








its always a thing and if you've watched some of my previous streams 
you'll have seen me spending time on this
that its its not easy to get the
the dc offset adjustment right on lisa choirs
and so i was thinking well could i can i change the circuit to make it 
better
in particular the dc offset
is
or the the the compensation for it
is adjusted in the air by by injecting a current into the the 
integrator op amps
would it be better to injected into the ot a's instead
no i'm looking here for the five tens and not seeing them so i think i 
must have dump those into the other bin

yeah

hope i didn't have these been swamped
no it couldn't be because the this is the board that takes the doctors 
and the inductors are here
anyway i built a prototype
or i modified an existing one then cut a trace on the board and rewired 
it
to see if putting in the the offset compensation elsewhere would help 
but it turned out it didn't
which kind of makes me feel better because it means that the earlier 
development work i did deciding where to put it was probably right
but it also means that there's no easy fix that will make it better
we just have to keep messing with them
trying to get those adjustments so yes they should be
so i mean on the one hand its not nice that i can't make the the coil 
it'd be better for dc offset easily but on the other hand it is nice 
that i didn't make a serious mistake when i first designed it
and it is about the the original design is about as good as it can be 
in that respect
silly you know you always want to try to make everything as good as it 
and if if there were a way to make it better i would want him



anyhow he ended up saying
matthew scala silicon smith is
improved or in exceptional
filter masterfully that being into our fortress reference if you don't 
recognize the way that
the game messages use language








actually maybe not i'm not a silken smith i'm a crafts dwarf
or something like that
there was a list on twitter from some sociological study back in the 
day when
sociology was or wasn't even sociology anthropology i guess it was back 
in the day when there was actually serious science
i
where they'd gone through you know a whole bunch of different cultures 
around the world and ranked different activities
for how masculine or feminine they were
i think the most
most masculine activity was hunting large marine mammals whales and 
walruses
in the societies where that is done at all which granted is only a few
that was very definitely a men only thing
i forget what the most feminine activity was
mining was very masculine but not absolutely so you know like like 
eighty five percent of societies considered that to be men's work all 
but there were also summer
where mining was a thing that women did
and making musical instruments was like third most masculine
which seemed a little surprising to me there's
in my frame of reference there's no particular reason why that would be 
something that
men would do and women wouldn't but apparently
in the system in the sample of different cultures that the researchers 
looked at it happened to be the case that that was
not a thing women did
ix with a few exceptions but fewer exceptions than whaling












so as most people do i'm just putting in components that are like low 
to the to the board
and all these others
will go in in a subsequent round of soldering the the dip sockets are 
also very low to the board but i want to solder them with a bigger tip 
on the iron so i do that in a separate pass

should i actually i think i'll actually skip the schottky diodes as 
well because those would benefit from the bigger iron trip










i've never actually done a successful raid on twitch
the one time that i attempted it it appears that the other channel i 
was going to
i stopped streaming will just like within the minute or so that i was 
going through the
the menus
but i see that the culture is still streaming and
two years and at the time i finish which will be
maybe another hour
maybe even longer but we'll see
anyway and may attempted then i don't even actually know if i have any 
viewers right now the twitch stream controller says i have one but i 
think once somebody's once somebody tunes in during a streaming session
it then says that you have at least one for as long as you continue 
streaming even if they all turn out really

i guess it doesn't want you to be discouraged
although i really wish that there were a wave just having it tell the 
truth discouraging or not




here
eighteen
this is supposed to be one of two eighteen kb sisters and i'm only 
seeing a spot for one of them

yeah ok there there is only supposed to be one
in the bills so i'm probably going i probably just counted out two
in which case i'm off you know i'll save this for
next one and probably i'll have a half dozen leftover



i don't know
i probably could find out but the the leads on these diodes feel 
crunchy when i bend them
then leads on resistors usually do
i wouldn't be surprised if its like these are steel plated with copper 
ore
and the others are copper all the way through or vice versa or something
there could be a difference in the plating but i wouldn't think the 
plating will be
thick enough to affect how it feels when i bend it
but there's definitely something different about the wire
that these diode leads are made of








































one king is
almost palindromic its brown black black brown brown
its not quite the same in both directions but
pretty close


that's that them for now






no
i don't see an eighteen
in here
so i guess i can use the eighteen that i reserved from the previous one 
but
it is strange that
they were countered that right there

oh of course i don't see an eighteen because that's this is a board too
so the jury's still out on that one






















the hello to peculiar asthma












the
the
the
the
the
yeah the the five tens are missing on this board they weren't in this 
bin and i can see that they were the thing dropped into the other been 
so that's that's just what's a consistent pattern when i when i counted 
them out that's the kind of thing that happens because of trying to
juggle two
two sets of pins at the same time
the if i were making a little bit larger batch if i were making like 
ten at a time then i wouldn't have even attempted that
but
doing just six corridors in one batch and trying to
trying to do all the work of one type before i move on to the next type
ended up making things more confusing
the
the
the

ok check for eighteenth yeah here are two of the teens i've also got 
one left over from the other things so i i think it must be the case 
that i just countered out
i
two for each build when i only really need one
so i'm going to have a few leftover
yeah
the
the
so let's use this reserved
eighteen k immediately
the
the
the
the
the
the
the point
they won't stand up on the legs
the
the maybe with this one in place
the
the
the
the
the
the
the
the king
that's true drawn out of
twelve here
the
i'm gonna go through and pull out all these eight teams because i see 
that there
are two different kinds
and so this may be the chance to like use up an odd one out
me
i have to go back to the
stockland is there to figure it out
yeah
yeah so i was doing this thing of you know try and having two that 
didn't quite match and that's no longer relevant because actually
oh
there's only one in the the build so that there are always going to 
match



so i have here
six

eight ten
and i only need for some gonna have six left over
does that work

alright let's say i had
twelve and i've used to so i should have ten here and i do that's great

and then we figure which are the newer ones the newer ones are the 
darker blue ones
so i will
have a miscellaneous combination that are
leftover hair
preferentially used via the older ones
these will be leftover for some
future building
there were a lot of eighteen k resistors that are houston
double handfuls in the
in the middle path vizio

but the corridors the chance to use up the mismatched ones


okay
after stuffing boards




you can see there aren't actually all that many parts
one of these builds
that is one reason why if someone is a
beginner wanting to what
build a simple kit i think a coilover is a pretty good choice
although they always seem to want to go for the biggest kits


but whatever i mean that i make more money on a big kids so if someone 
wants to
by that i'm not going to try to dissuade them too much
still i think if someone has never built one of these before they may 
be better starting with the queller

on the other hand i mean the leapfrog is a better behaved filter once 
you get it finished and there is that finicky adjustment much really 
both of them have but its finicky in different ways on the two
i would like to think that any of my kits are resemble starting points































tens
like they couldn't remember the other been here we go













five out of twelve boards done for this stage
i'm not sure whether i really want to hang on and do
all twelve in the stream session
i meant to our strange now witches
long enough that i would consider it ok to knock off at this point
maybe i'll just finish this one and then i'll be out to
halfway through the batch

actually i'll finish this one and then i'll check whether anyone i know 
is still streaming
i think both area and the culture have to
finished their streams during this time i
was keeping an eye on twitter there
but if either of them is around or if anyone else i know is then it 
would be a good time for a raid




























































alright
that's the sixth board
and in as much as i'm not even sure
whether i still got a few years right now
i think that's going to be the stopping place

so although twitch
because of the software compatibility issues its not going to show you 
a little bar along the bottom saying that the goal is to
fifty subscribed not even subscribers fifty followers
the difference is important because you can follow for free and i hope 
you'll do that let's see if we can get that forty for up to fifty and 
other than that thank you for watching and i'll be back
a week from today on election day
and have a nice day
oh yeah
yeah the
the
