i
good afternoon welcome to my november eight stream in this stream i'm 
going to be working on the qoyllur v cf
i'm down to i think three of them in stock right now so i recently had 
an order for a couple more so its its time to replenish the stock and 
build a few more of these i think last time i did this was quite 
recently on on the stream but it was with the
with the
how do you say that the kit
and this time its going to be assembled coilovers
no i last when i was working on the kits i think i spread them out over 
several weeks and i'd really like to avoid doing that because it leads 
to inaccuracies in keeping track of what parts i've used and when and 
that sort of thing its really high
hard to make sure that everything gets properly recorded here so i'm 
going to be sticking i'm going to probably not complete this project on 
the stream i'm gonna do some other work here today and then i hope that 
within the next few days i will have it have it done and not streamed 
and then i can do something else next week now
last week you saw me working on the new website that is going quite 
well i've been making pretty good progress every day that i've worked 
on it so i'm hoping that within this coming week i will be able to 
switch over the domain name and we can all look at the new new web
zine which is really my best best web design yet for the storefront i 
mean its i had the shopify storefront back in two thousand and 
eighteen and i got it to look pretty good and then i had to leave 
shopify in a rush because they screwed up browser compatibility and the 
storefront that i
i had on bigcommerce was kind of a compromise and i'm hoping that the 
new one even though i've had to design it also in a rush the new one 
actually looks a whole lot better and i'm hoping i'm going to be able 
to stick with that design for a while even if i end up moving further 
in the new year
yeah
i have a friend who's hoping to start up a business of hosting 
e-commerce sites and it may be that i'm going there but if i do i'll be 
doing it on
in less of a rush and i hope with better and better web design so let's 
get started here i've got maya six pins already for putting parts in 
and i'm going to start with board number two which is the one further 
to the back of the
of the module
so first thing i'm going to need on here is some film capacitors
sixty eight hundred puff
hello to have these two
let me see what the twitch
counter says it still says i have zero viewers so i don't know if its 
just not counting have this to properly or have this too is a bot
i would really like to be able to get more room
more more viewers on the channel but
that is ultimately something that i don't get to decide
one of the things that was really an issue for me towards the end of my 
academic career was that i was in a situation of nearly everything that 
was important to me depended on the voluntary actions of persons other 
than myself
and unfortunately that's probably part of the human condition it may 
not be something that i can really
really eliminate but i would like to reduce it as much as possible and 
that's one reason i work for myself now instead of being an employee 
somewhere
ah
and unfortunately getting viewers on my twitch channel is another of 
those things where i can
i can do my broadcast each week its somewhat under control of somewhat 
under my control or whether i actually do the work make a good blog 
broadcast and to show up every week but its not under my control 
whether people to me
and that's unfortunate it means that
twitch broadcasting is for that reason
not the ultimate in what i would really like my life to be all about
but there are two six year one hundred puff capacitors in each bin and 
next its time for the
the ceramic decoupling caps
and this is my opportunity to use up some of some of these baldwins

huh
yeah
its been a little while since i've used this this particular streaming 
setup with the laptop because
i've been doing other kinds of streams recently

i am guessing that we probably won't
be seeing mr baker this week anyway
because
he went to halifax to get a guitar
i think it was halifax
and somewhere in atlantic canada anyway
and i don't quite understand how this works but apparently part of 
getting a guitarist you have to
you have to drink a on the schooner
he was saying on twitter that
the bartender said they'd never sold that much schooner in in one night 
before

i have not done that but i do recall that on the last st patrick's day 
before the world changed
i went out with some of my friends to the hong kong noodle house and 
drink all of the beer that they had
and then an irish priest of my acquaintance
picked up the tab for the entire table so i not only drank a whole lot 
of chinese beer but didn't even have to pay for it
fun times


see if i can get these windows arranged the way i would like them
we seem to have one viewer now that's great

and it'll just take me a second to
get this adjusted
there we go
yeah
alright for for axial ceramics
in next week's electrolytic the qoyllur is actually a pretty simple 
circuit there's not a lot of complexity in it
although it does have one or two little little wrinkles
as is fairly often the case i found myself with extra extra amplifiers 
in in the chips i was using like a tale of seventy four b
op amp chip in there that has four units so if as turned out to be the 
case the basic corridor design needed seven of them all then if i use 
two chips i've got one one unit left over and then i went looking for i 
mean it is possible to just deactivate an unused unit
but i hate to do that if i'm going through the trouble of including a 
whole chip i want to use every one of the units in it
so i ended up finding a circuit online that i thought looked 
interesting which was the full wave rectifier with only one diode in it
i mean a full wave rectifiers
switches the direction of a current so when not
when the voltage is positive that puts out the the just passes the 
voltage through and when its negative it inverts so you always get 
positive on the output
and usually the natural ways to do that would involve at least two and 
sometimes four diodes
so now a diet costs like two cents so you saving one is not necessarily 
really all that important or valuable but i thought it was really cool 
that someone had come up with a clever op amp circuits that would allow 
full wave rectification with only one died so that's in
weiler and it also uses the otherwise unused
op amp unit
now
in at least some places like on the label of the do it yourself kit
i call this module
a filter and rectifier
i haven't gotten a lot of feedback from users that they really use the 
rectifier section i'm not sure all of them even really understand that 
that's what it is i think some just sort of think hello casey banner 
life i think some just sort of think that the filter has two inputs and
i don't know what they think of the fact that the sound so it sounds 
quite distorted if you if you use the one that's labeled with the diet 
symbol and its rectifier input
but
you can't always really predict or certainly can't control
how people are going to perceive or use a circuit design
its time here for the foils
he's twenty two mil or millie henry inductors
they give the coilover its
its name
don't know if you saw that but my luck white here just seem to change 
its the intensity
then i've had a few power bumps recently this morning there was a a 
power outage for
at least about ten minutes
i actually was
just getting ready to go out to one
mail a package when when the power went out
so as i was going out through the neighborhood i kind of looked around 
and saw that right where i lived
the other houses seem to have their power out
and the stop light at one nearby corner was flashing red so it wasn't 
in its normal state but it was still getting power from somewhere i 
don't know if they may be battery backed up
but by the time i got to the post office at least the lights were on 
and the post office i don't know if they didn't go out anyway or
or what but power outage was probably quite localized and it clearly 
only lasted maybe fifteen minutes at most
but there have been several like that in the recent past
kind of worries me
i mean i guess our power problems here in toronto are nothing like as 
bad as they've been
let's say california or texas but
it would be better that that not happen

male headers


putting a big part through to this morning
ah
and it was noticeable that you know there are supply issues for some 
parts
there are things that i would expect to always be in stock that were 
like well you want one hundred but there are only twenty in stock so 
will backward or the rest that kind of thing
i don't think its really going to be a big problem for for my 
production
but it certainly looked iffy for some of the well exactly the 
microcontroller chips for the upcoming
gracious host module i have those now so not too worried about them in 
particular
i
yeah
but it does mean for instance that like there were items where i ended 
up having to buy from other more expensive distributor because the less 
expensive distributor was out

viewers have probably heard me talk about the large versus the small 
resistors
and i prefer to use the large ones in kids because they're easier to 
handle and easier to read the little color codes
so today when i'm not making a kit
is my chance to use up some of these smaller ones











think these five ten home resisters though
small resistance value there
if i remember correctly they're used in this
in this design at the inputs to the
to the ot ot a chips because the ot a is a basically a voltage 
controlled amplifier although really its current controlled
and it always has a fair bit of gain
so in my case in this
in this filter you actually want the output of the amplifier to be at 
roughly the same level as the input
so what happens is the input goes through a voltage divider that knocks 
it down
significantly
to be just the low low level that can go into the gym
into the ot a input
so the divider has like a i guess its probably one hundred cave
maybe not and you know why
larger resistor on top and one of these small ones on the bottom
these ones are small in terms of size but i also mean small in value
and that's the years it down to
to the level that the
oh to your needs
and this came up recently because
someone emailed me saying that he had mis patched his qoyllur heed to
accidentally plugged the output
into the output of some other module
and since then he thought that maybe his qoyllur was had a higher noise 
floor
so he wondered if he damaged it
its actually been a little while since i designed this so i had to go 
back and look at the scheme headache and see if i could figure out was 
that at all plausible and i told them probably not
the thing is the the outputs go through
teal o seven four chips that are pants that basically serve as buffers
and so in order to damage it you buy miss patching you would probably 
have to damage
one of those chips and they're very rugged i mean
it says in the year
in the data sheet that it will withstand a indefinite duration short 
circuit on the output its never wise to really push it to to do that 
in practice but i have actually seen it happen where i i think i was 
building a a leapfrog at the time
time
and there was a solder bridge on the board that had the effect of 
shorting an op amp output directly to
ground
and the op amp i mean it was like a minute or so between when i powered 
this up and when i discovered that
it wasn't working the op amp chip in question certainly warmed up but 
it wasn't fried that leapfrog was was fine after i corrected the 
soldering year
and so i don't really expect
there's now that wasn't a qoyllur but it is the same chip that would be 
in the qoyllur i don't really expect corridors output rpm to be damaged 
by
especially because it was it couldn't have been directly short
there is a protective resistor between the the op amp chip and the 
outside world
and honestly that that resistor is there mostly to prevent the qoyllur 
from damaging other things you know the saying about an unbreakable toy 
that can be used to break other choice i don't want someone to fry 
their whiz bang expensive module that they got from somewhere else
by plugging it into a qoyllur and then blame me because i designed the 
qoyllur
so in order you wouldn't even be able to put as much load
onto the coil or softbank's as you could with a short because there is 
no direct short it would have to go through that resistor
and so
even in the worst possible case imaginable of output to output shorting
its hard to believe that you would be pushing the op amp anywhere 
outside its specifications
and it should work just fine
people don't always really understand that electronics to a large 
extent doesn't really wear out with us i mean there are certainly 
exceptions mccain anything that's of a mechanical nature sure if you're 
twisting the knob back and forth too much you know you've
play with with too much into it'll be injured
but just running
running a amplifier
within its stated range and if its not overheating or anything
you can do that day in and day out and you may actually be better than 
not
then turning it on an awful lot because you won't be thermally cycling 
it
so what i told the fellow came down to well i think most likely you're 
just our list hearing something you already that was already there and 
maybe you're noticing it more now because you're concerned and paying 
closer attention
and he was happy with that description
i
and i also told them and this gets back to what i was saying about 
voltage dividers that the coilover is never going to be
a really quiet filter because of the way this gain staging works
the ita chips have a fair bit of gain so in order to get the output 
from them at a reasonable level you have to knock down the input to 
quite a low level
and that puts its not necessarily all that much above whatever is the 
existing noise floor

and if you want a really really quiet filter then you probably should 
be using some other other filter design
it would be interesting i don't have really at the moment
a product that i will describe as really quiet that's not really with 
the direction that my musical interests go
but it might be might be fun to think about you know if i wanted to 
design a really quiet filter how would i do it
i probably won't design another filter at all in the near future because
i've got two out of seven modules in my line are filters now and
how many filters do people need
but i might want to think in that direction in terms of a v ca because
i do kind of need to have a v c a and my line and i don't at the moment
k now its trimmer time
i really ought to get some sort of frequent flyer bonus with the 
trimmer manufacturers
cause i just go through so many of these
you know like i'd like to have some kind of a
little punch card to order a thousand trimmers get one free 
unfortunately that's about what it would be


okay i think now is going to be the time when i use one of these this 
last gray one cause i need two in each bin
and
i've got blue ones and grey ones and i only have one leftover grey one
they're equally good and they don't need to be matched
but i still kind of wanted to ship nacht ones in kits
and i do normally use these two at a time
so i've been saving that one extra one
for an occasion like now when i'm building a
tyler or something
myself
that's part of the thing of having a unique handmade product right 
somebody's going to get the special quality that has a grey and a blue 
one
and then they can have a rare collectible one i guess















k to twenty k


those are two twenty games
don't have any other snow
i usually try to use up whichever bag has the fewest in it
or draw from the bag because fewest in it because that's staple like
if i take
if i take resistors i have a bag that has fewer students than after 
doing that it'll have even fewer so
so i'll also be taking from that bag in the future until it gets used up
and this will normally mean that i'm following something like first in 
first out which is how i value my inventory
and makes a lot of sense right i mean these these components don't 
really go bad but it does make sense to use the oldest ones first
although when there are some variations like like that business with 
the grey ones and the white ones not grey and white grey and blue
then
then i may vary though the policy







okay that's all the resistors
i will need a couple of dip sockets and a circuit board
so a dip sockets
i was going through those
i actually decided not to buy more
in my current
current order that i put in this morning
because i was buying so many other things i don't absolutely need more 
of these yet
what do you guys mean that i will need to have another order in the 
near future
and i don't know how necessary it really is i mean the sockets are 
expensive and they're not electrically necessary
but at the same time i know that do diy builders like to be able to 
swap chips and that does make debugging easier
if you soldering a chip and you do it backwards then ah
it'll be destroyed and you have an annoying deciding problem in order 
to replace it
whereas if there is a socket then okay you've still destroyed the chip 
that you can pull it out and put in a new one without probably needing 
to resort or anything else
the one place it would really be nice to use a socket is actually in 
the gracious hosts because there's a microcontroller chip
i
sorry yeah ok have to deal with that

hang on here

see which one is this b or
time out
banned
there we go
hello to be more
i guess its a good sign if i'm
becoming big enough to attract bots i haven't seen one of those in 
awhile

but i would prefer to have have human viewers rather than spambots

yeah so with the gracious host if you screw up the programming of the 
chip tom
then if you don't have
the equipment for in-circuit programming
you would kind of like to be able to pull that chip and put in another 
one
otherwise you may have bricked your build
the trouble is that chip has a much higher frequency on it than audio
i
clock signal was four four megahertz but the usb
bus itself operates as high as twelve megabits per second
so
in there then there's also stuff like the chip needing really heavy 
decoupling
those little axial lead to passengers i normally use are not enough for 
it
needs a bunch of special special treatment
so its kind its kind of preferable not to have a have a socket 
because the sockets are really in pairs
the ability of the decoupling capacitors doesn't stop someone to do 
their job
so between that and the fact that there are a lot of expensive parts in 
the gracious host and i'm trying to keep it at a price point people 
will be happy with
i opted to not put sockets on the digital chips there will still be 
sockets for the analog ones but
i think that to complicating the my picture and maybe making the 
decoupling not work as well as it should and so on its not worth it in 
the case of the microcontroller chip in particular
so why
so that's my call right its
i call is that you're going to have to solder the or i'm strongly 
recommend that you side with microcontroller chip right in
and i'll just say in the build manual hey
make sure that you know what you're doing before you do this and make 
sure that you put it in right way round

okay so that's all the parts for the board too
and now i can work an important one
pretty fast
i went really fast in fact for only thirty seven minutes in

i may even be able to get to do some board stuffing
here in the stream
hello meta views
i don't know if that means you are if you have views on the
artist formerly known as facebook or if that's just to
incorrect assumption okay so thirty three puff capacitors and if i 
remember correctly least they're not actually in this bin yeah i see 
twenty twos and several other sizes but no thirty three so they're 
probably on lisa schools here
let's see yeah here we are
thirty three
and i have one
pre-cut here
from previous episode
and i need five more


i'm not being as careful about labeling these right now because i know 
that
i'm the one who's going to be handling them and i know what a what a 
thirty three and and what a one hundred look like
speaking of one hundred
those are probably also on a spool
let's see yeah

i try to avoid actually behind these unspools because they're kind of 
annoying to deal with
the real as they call it is not really a spool
is what they are its what you want if you've got one of these robots 
assembly machines
because the robot will have a whole raft of like twenty or fifty 
holders for for these reels and you throw them all in when you're 
setting up to do a production run and it just zooms through
assembling all alpha
all of the parts from the appropriate reels
and they did you know for throughout the frugal era that robots were 
capable of doing through hole
through hole assembly
all this wonderful technology of wave soldering and automatic clinching 
and cutting of leads and so on that is largely seen as obsolete today 
because of surface-mount emphasis
in a surface mount machine works the same way just because you're a 
little tape with the pockets in it that
contains the surface-mount components instead of fun
i'd take this down for the third time in a few minutes and instead of 
instead of taking the
through hole components off the off the tape
hi

if i could write to
not order more of these


in my inventory lists said i had like five hundred room
how many quantity three hundred and here
so yeah that's plausible

i mean i guess they take up a lot less space from yours there in the 
above path like this that's one reason too
do you prefer



okay now the
earlier
building a full wave rectifier with just a single switching diode
and here we are here
single switching targets
like i say its
kind of a foolish exercise because
these diodes cost i think less than two cents each
hello def be
so i don't know that having a a special full wave rectifier circuit 
that only work only needs one diode
don't know that we're really saving much
but it is fun
its cool to say to someone who knows on how one of these circuits are 
constructed
hey we've got one that uses only one diode and then they can
think very hard how to how that would be possible
and i need the four point seven sceneries


i have a whole lot of little little bags with just a few zener diodes 
on them
because of the testing i had to do when i was building the fifth sign 
bank
it has zener diodes in the the feedback loops of the amps to try to 
limit the the output to the right level and i had a heck of a time 
picking something that would that would get the level i want it so i 
had to just buy like eight or ten different values and test them all 
until i got something that worked
and at such time as i reorder then i guess i'll have to check the new 
batch that make sure it still works
because i'm really using them a little outside there well significantly 
outside their rated
then their rated power level
not in a way that will damage anything its just that these these 
diodes are typically rated for like well it'll drop this much voltage 
at ten mil amps and i'm using it at a much lower power level
at which level it will drop a higher voltage but how much higher is not 
necessarily well characterized
alright these are four point seven
i use a different pendant for for them because this tape that the 
diodes are on
doesn't soak up the ink the way that the the paper tape used on things 
like resistors does
so i've already established if i use my usual black pen which is water 
based it won't market properly gotta use the solvent-based permanent 
marker



alright nuts standoffs whole bunch of
hardware here




huh






there'll be more knots needed in this project later when i get to the
mounting hardware for putting the modules into the rack but
those go into a separate little bag so it makes some sense to wait on 
counting them out



okay
yeah i have here
looks like there's more you know there aren't
looks like just enough
of these three both are teens


thanks to recover

used up
more of those are already on order
and i already have wait a minute these are elevens
yeah plenty of eleventh here
huh






machine screws




two of these in each but



when these are fresh like this they look kind of blue
but they very quickly lose that can they turn slightly duller silver 
color
i'm not sure anyone would notice them except me but
something i notice
oh boy
its time for the famous lumberjacks
i
you've heard me rant about them before i guess i don't really need to 
again
i need seven for each been six pins
that's going to mean
forty two i think
ten
fifteen
twenty
twenty five
thirty
thirty five
forty
forty two

i usually buy these five hundred at a time and it seems like i'm still 
always running out of them because they're in almost all of my products







seven








its fourteen







twenty one







twenty eight









thirty five






and forty two
he's my emo more lubricant soon

okay so next it'll be the
board to board connectors
both male and female
these are low too but they're also an order right now
and actually these were one of the items that there seems to be a 
supply crunch for
especially their female counterparts
so i'm expecting to get
enough for my immediate needs in the next few days but
then there'll be some more backward




not quite as long on females as we are in males though so that helps




okay so now the
discrete transistors
and i think at this point we're not want to where did i put my discrete 
transistors
i was expecting them right here
i think at this point we're now onto the
ss eighty eight fifty d
transistors
strange
they ought to be right here
so i probably put them in a safe here we go
i must have seen there was a space on the shelf there and i put them on
with the other
okay so i've got these ones
and these ones
usual rule i take from a smaller bin or bank
because these will be the the initial bench then i got to see whether 
they were any good
and then having determined that they were
i bought the larger
larger bag


just spot checking a few here to make sure they have the right markings 
they do
true true
two point two and two and two go
alright now we're onto resistors and i probably ought to
lubricate those scissors first
so i'll just go grab a kleenex back in the second


check one two okay








this stuff is supposed to evaporate quickly
leave behind a film or foil
it doesn't actually work as well as i'd hoped
so its kind of back to the drawing board in terms of formulation but
i want to use up that batch before i tried too hard to make a new one

and once that is somewhat dry
i'll be wanting to what
measure some one k resistors
and also some one point eight i think
yeah if those around here
one can one point change














the
the those in fact are the output protection resistors
i was talking about earlier
so in order to damage the chips in one of these coilovers you need to 
burn up one of these three sisters first
and you can't really do that because the
the output voltages from your rack modules even if evening as i say the 
most extreme case
are not going to put enough current through there to to really burn it 
up








the
the two point seven k is next



are these ones are there any others
looks like not

this is another value for which there's just one in the design
it looks like i'm up to three fevers now that's great
part of the thing for
getting special privileges on twitches you have to be able to maintain 
average viewership of three
and i think i'm probably pretty far away from that because average 
viewership means not just you get three people tuned in at one point 
but you get
like if there is a period during which you have no viewers then that 
has to be balanced by
perhaps an equal length period during which you have six because its 
average over however your last however many hours of streaming
but i am getting pretty close to
to the fifty
fifty follower mark
which is another important to
important threshold
i think it may be that when i hit fifty followers i get to define 
custom emoji or something like that
or they call them emotes which i guess is correct because they're not 
really emoji they're not registered characters with the unicode 
consortium
i dunno what i'm going to define as my emotes
i mean maybe i shouldn't count those chickens until they're hatched but 
its coming up pretty soon
hello mr lee news
ah
you know they probably should be themed
i like to follow y'all keep a goat who does cute animal pictures
and so yagi has like each of the characters has their own emotes and 
there's one good one that is like a little fox eating a taco and
i don't even know what that signifies in terms of like when is the 
moment when you would use that but its cute
but i don't know if maybe i need to use like as a few schematic symbols 
like someone once they once i and they reach the level where this is 
possible someone can type a code and get an op amp appear in the
in the chant
i guess the thing to do at that point
when it gets more imminent is is paul my viewers what kind of emotes do 
you want
might be interesting to know what the answers are i have pulled the 
wrong been there but i will need this one in a second
think i'll leave it there and grandpa next one
cause right now i'm looking for the eighteen kick
resistors

okay one of each of these one of these in each spin
hello at ten
or a tenant
turn off that's an egyptian god i think it might be






alright eighteen k
not to be confused with the one point dates that are also in this board






i do that right
think so
and next is twenty two


huh












thirty six is in the same bin
nine there there's thirty six
all these resistance values inherit between twenty two and forty six
are ones that i use a lot like significant numbers of them in popular 
modules so
they're in bigger bags and i don't have very many of the little little 
ends and remnants
because the inventory on these ones circulates relatively quickly

when i'm designing a module or building a prototype or something i 
might buy just like a hundred of these resistors it doesn't really make 
sense to buy them in a quantity smaller than that
but then once i'm actually producing the module bump up the order size 
and get them typically one thousand at a time
the whenever i run out of one hundred case i may actually get an entire 
box like you saw earlier
that came about because i ordered one thousand of them in to
the distributor screwed up they shipped me instead of two packs of five 
hundred they shipped me a pack of five hundred and a pack of five 
thousand
and i felt i was obligated to tell them
and i did and they ignored it
and given that i had other more significant issues that they had to 
sort out i dropped that one
but i have found that having the big box of one hundred k resistors is 
kind of nice so i'm thinking whenever i do run out of that big box
which won't be too far into the future because i do use a whole lot of 
those i will actually order them five thousand at a time instead of
just one thousand at a time
at that level there's not a huge quantity discount but there's always 
some
and its nice not having to restock them
i wouldn't want to do that for every resistor value because there are 
so many different ones but
i don't want to have a big ammo pack like that for every single value 
on my shelf
but hundred k in particular is
when i use so much that it probably does make sense
i mean also there'd be the expensive of all their inventory if its a
if its an item that i'm only using like one at a time in an unpopular 
module
then having five thousand of them doesn't make sense but
there's like a double handful of those hundred ks in pretty much every 
year
every module i make so
special case











hungry
okay
i
now i have to go get the
panel parts
yes them that would take me a second back in a month



there's a lot of money tied up in this spin
because these parts cost a few dollars each and then there's they're 
used in many of my products
so
is there a trade that's already started
in this case i need three of them
for each
for each of my six corners i'm building
so that'll be three
six
nine
twelve
fifteen
eighteen
try not to disturb this tray as i did last time i have a spill of them 
maybe it wasn't last time but it was caught on video in one recent 
stream anyway
this way
ab down here
maybe the one here




















ok spring musher
lock washer


















finally the nuts

each of these has its own function right the
the nut is the thing that holds it in place
but not content to loosen over time
so the lock washer his teeth in it that dig into the surface of the 
nodded
concert to stay in place especially with regard to vibration
but then in order to make the spring washer work you need to
controlled reasonable amount of pressure on it
so the spring washer does that
and also protects the panel from having the nut
the the lock washer dig into it
i have heard the claim
no
an old timer i spoke to one
the forum formerly known as my winkler
that this this thing with the teeth on it is not really a lock washer
he wanted to call it a serrated ring i think
and claim that the purpose of it was to cut through the finish on the 
panel
and form a grounding connection
and i'm sure that there are pieces of panel electronics where that 
would be true
but i don't think its the case on these parks in particular

the
the anyway if you if you believe the serrated ring theory then pudding
media
spring washer between the serrated ring and the panel would be a big 
mistake
because it would prevent their teeth from being able to to do their job
alright
three and three and three and three more threes
that's those and that's those now constituted a very significant 
fraction of the the value of the parts in each bin
because resistors cross very little

the

the
the
the
the g twenty k
go
the
the
the

the other resisters now i am not going to actually count out the tips 
yet the the chips
because those will go into their sockets basically in the last step
but i am going to count out
sockets for them
team




and that's almost all the parts
its interesting that bill of materials usually is like at the table 
laid out like this with basically exactly the parts that have reference 
designators on the schematic
then in any real build there are going to be other things that don't 
fall into that category but still need to be included like these 
circuit boards


and the panels
i don't have those within grabbing distance i think i do
i'm going to need to buy more of these panels very soon i think i have 
seven
being a hair
yeah and i'm going to need six for this build
so i won't be able to build any more of these until i get the next 
package from berlin


probably won't count out the knobs yet
then i might as well count out the
these things
cable ties
i ship two cable ties in each kit that uses them even though there's 
really only one needed for the build
because if you screw up and have to cut one away
its nice to have a spare

alright
that is awful
all the parts countered out
i've only been streaming an hour and a half
i'd like to make a little bit more progress so i guess the next step is 
going to be to do some of the board stuffing
and i'll do that on this board first because
this is the point that i normally build first when i'm doing one of 
these builds
i'm guessing i probably won't have time today and the amount of 
streaming i want to do
to actually start soldering these but i'll at least
at least to i may or may not have time to do all aboard stuffing we'll 
see how fast that goes
there's not really all that much that needs to be done this is a pretty 
simple build
yeah
if you're looking for and like it
an easy starter build this is probably a good pick
so i'm just going through here and pulling out the components that are 
going to be need need to be done in a separate step
cause i like to build from the bottom up to the the little parts that i 
cider with the small soldering iron tip first and then the next pass 
onto probably the dip sockets because i like to use the wider tip for 
those
it goes faster that way

and then after that it'll be stuff that sticks up off the board
needs to be held in place









the
the there are all kinds of gadgets you can get to help with bending 
these leads
and honestly i find it easier to just sort of learn how to do it with 
my fingers and know how bigger distance i want them to be
that does mean that they end up sometimes not being built to quite the 
perfect size but
the little bit of practice i am usually able to guesstimate it pretty 
well
and that seems a lot easier than messing around with the
little pending jigs i guess if i had one of those that was completely 
automated if i had some sort of a machine where i could just feed in 
the spool and turn the crank or whatever and have it spit them all out 
and i'm sure that does exist although
probably not a big thing because usually if you're automating it you'd 
also be automating the insertion and the soldering
so you'd have a robot that does everything not just cutting and bending





its often an issue with these coin learn how to adjust them for 
minimum dc offset
and after doing one that seemed to be especially tricky
i went and i looked back at the design
its to try and figure out if there was some design change i could make 
that would make it be better
and i actually took one of my prototypes and cut some traces and 
rearrange components on it too
see if i could apply the offset knowing at a different point in the 
circuit and have that be better
and the answer was no
at the at least moving the the connection to the other place that i 
thought might be a good idea it did not actually make it better it made 
it worse
and i was a little relieved because that meant that you know my initial 
design was not so bad after all and i was not going to end up with a 
situation of trying to redo existing boards or anything like that
but i guess i would have preferred to have that inconvenience anyway 
because it would mean that then i would have future ones that work 
better now there is my phone i think i better see what happens hang on


nobody there
at least not within the few seconds that i was willing to wait i've 
noticed that's when its a telemarketers telemarketer or something very 
often there's a pause between when i pick up and when i actually hear a 
voice
and i think that a legitimate caller
is unlikely to to have that pause
so if i don't hear a voice within just a few seconds after i pick up
then i'm inclined to hang up
there was a period of several weeks where usually daily often more than 
once a day
i would get a phone call from somebody who thought that i had phoned 
them
and as far as i can tell its because telemarketers were forging my 
phone number
on the caller id so
somebody gets a missed call that was from a telemarketer into their 
caller id says it was from my number
and apparently there is little or nothing done in the telephone 
networks to make sure that caller id information is correct
so if some foreign
telephone company issues an incoming call to the local telephone 
company they can put whatever they want in there
in the caller id information and the local telephone company will not 
check well that's not actually a phone number that your your your 
foreign companies responsible for they'll just pass it through
and it seems like that's a really bad thing but that's the way it works
and of course part of the problem is that then
i mean heaven forbid the significant number of these people are 
actually not calling me because they're picking up on the first go and 
then they think they gotta a spam call from my number
and
so on
one one fellow was borderline belligerent he said well some one from 
your number called me know nobody from your number from my number 
called you i did not call you i'm the only person here well but it was 
your number on the caller id is lying to you
i guess that's you know being someone who works with machines a lot i'm
inclined to recognize that mission machines can
ah
can lie now casey banner in life says what they do is robot i'll you 
and then only if you pick up the multiplex you want to a real operator 
yeah i mean they know a lot of people are not going to actually be 
picking up so they're trying to save time for the real operators 
because they have to pay for those
so they've got the robot that makes the outgoing calls
and then if they've got a lot of humans
it will put punt you to the first available human so that way a human 
isn't waiting for you to pick up
and yeah and its understandable and also
that's when its a telemarketer but also when it was one of these 
people who who thought i found them i don't know why but people 
returning that kind of call also often seem to have have a big delay i 
think maybe because if you miss a call on your cell phone its because 
like you're driving or something so they
i dunno maybe they push the return call button and then pull over too
try to actually talk to a person or i guess also you know if somebody 
calls me i will pick up and say hello now if they think i called them 
that they're expecting me just starting with whatever is my pitch
so if i just say hello
then there's this long pause because they're expecting me to speak
ah
and very often with that kind of call its like a confused senior or 
something so i don't want to be rude to the person they're as much a 
victim as i am
and i try to explain to them well i didn't call you i'm sorry but you 
shouldn't return calls from numbers you don't know anyway that seems to 
have tapered off in the last few days so i'm hoping that the spammers 
have moved on to greener pastures i don't know why they would choose my 
number in particular it may simply be random choice
choices and it may also be that they randomly choose from among numbers 
that actually exist

i was not pleased that rogers cable who manage my telephone connection 
didn't really seem to think that there was anything they could do 
although that probably is true that there's nothing they can do because 
you know its a
some third party is lying to some fourth party and neither i nor rogers 
can do anything about that until well until the person tries to return 
the call


rogers told me i should report it to the fraud center but
i went to the fraud center reporting form online and
there's not really much you can do with that form when
i know neither the name of a corporate nor the victim
all i can say as well some third party is lying to some fourth party 
about me

one of the more talkative callers i i told him will you know you should 
complain about this because
there's more that you can tell them then than i can
the i mean really we were hosed as soon as we allowed businesses to use 
the telephone at all
but its probably too late to do anything about that
the trainees around
i have all the color codes read in a consistent direction
from top to bottom on the board
the
the
the
the
the yeah it looks to me like if i finish this round board stuffing 
forth the six modules that will be about the right amount of str
gaming for one day
the and there we go that's two out of four
the




the
the so i mentioned the power failure this morning
but
also around midday
one of my cloud instances rebooted
for no apparent reason
i was logged in at the time and
there was a point where it just stopped responding to to ssh
and then
couple of minutes after that i was able to log in again
and i had an email from the cloud service saying yeah the watchdog 
rebooted your machine so
there didn't seem to be anything unusual in the logs i don't know
what would have caused that
i wouldn't think that's power failures happen in in the data center at 
least not
without a whole lot of other help workings you know
and also i had another instance in the same data strict data center 
that too did not did not have that happen so i dunno i have a ticket 
out to them asking hey is there anything in your logs that would 
indicate this
the instance is capable of rebooting itself but there would be no 
reason that it would that i can see
and it wasn't the instance on which i'll be running my storefront but
given that i am going into
running my storefront on on a cloud instance very soon
i'd kinda like to know that they're going to be stable
i think that that instance that rebooted had an uptime of more than a 
year at the time
so we you know if it were something like the cloud provider decided 
while we've really need to reboot these instances for security patch on 
the kernel or something
its conceivable that they could
reboot instances to do that and even if it were something really 
critical that they might do that without telling me although that's 
really stretching the point
we'll see what they what they say on the ticket
but its quite possible that its just going to be while we don't know
no real harm done especially because it wasn't a user facing instance 
but
a little bit concerning because i could have other other things going 
on that would not like to be rebooted
the
the
the
the
the
okay
its the third one




the
the like the
silk screening king is a little heavier on this woman not the last 
that's you know there's a certain amount of variation in the 
manufacturing
so as long as each one is within tolerance its good enough but
you can see that there's variation
i mean
probably nobody but me was routinely looking at two of these boards 
next to each other
so its unlikely you'd be noticed
but i like to imagine that at some point in the future when i'm famous 
there are going to be people you know trying to figure out well which 
serial number range
is your queller from was this before or after the switch to this 
manufacturer or that sort of thing
like treating them as real collectibles



































okay
its the fourth one there
yeah i'm hoping that suck
once i do this
board stuffing i'm probably not to want to work on it more today but
i'm hoping to be able to work at
all of these sided up and ready to go within the week
since we're only at monday now


and that's on top of the up the other stuff the time
doing in particular for the website its looking to me like within the 
week is also my timeline for cutting over the dns
on the website
and at least in the first stage i will still be keeping the bigcommerce 
account
and when you go to buy something it will then take you to the cart page 
that is still hosted on the old bigcommerce account
but i'd like to move beyond that at some point in the near future as 
well
he could be as simple as just telling people
if you want to buy something you're going to have to email me and then 
i'll send the way i send you an invoice through stripe
but it would be better if i could get a real shopping cart working on
on my own systems
thing is i don't know how much effort i want to put into that
because in the further future i would be moving to somewhere else most 
likely anyway
so its do i get enough orders in the next couple of months
i
orders that i wouldn't get if i didn't build my own card to make it 
worth building my own card
on the other hand i could find that i like hosting my own system so 
much that i want to keep doing that a longer time
and in that case it would make sense to build my own card
and i also have to figure out my relationship with stripe
because stripe actually did the same thing to me
one day i went to log in and couldn't
ah
and i have a pretty strong feeling that once a site has done that to me 
that's it means that i have to leave them
however stripes customer support was a fair bit better than bigcommerce 
is
they did some kind of special casing in their javascript that would 
allow me to log in
so that means its less urgent to move away from them and it also means 
that i'd like to reward them for trying to help
but it really may be wiser to treat that as well that means i have a 
longer timeline for moving away rather than that means i don't have to 
move away because its virtually virtually certain given that they're 
using all this whizzy javascript stuff that eventually there will be a 
change that is breaking and that they're not willing to do something 
about

and i don't want to have my money going through a service that
might one day just not work
so it may be even if i continue using stripe in the short term that i 
should him also as soon as that things are stable on the new system
i should also start looking for replacements because i could 
conceivably run more than one in parallel
and it would certainly be better to get the stripe replacement up and 
running
ah before such time as i might really be forced to leave stripe
i was looking at square as a possible replacement for stripe they 
seemed to be very similar of course that means they may also be similar 
in terms of also using java javascript foolishness
so it could be then i might go to create his square accountant
find that my browser doesn't work with them either and to
it would be better to know that before i commit to them


but first things first
i now have nearly all the content moved over i do have all the weblog 
entries moved over and those are the crown jewels but
there are a couple of product pages
on which i have to do some html cutting and pasting
and then a lot of sort of behind the scenes stuff i have to check that 
all my search engine meta data looks the way it should
and i guess deal with the rss generator
that's a pretty small thing but its a thing that has to be done
i don't want to cut over the dns until you know i'm really sure that
everything is as it should be on the new site because i want the new 
site to be a clear improvement
i don't want it to be and people go to it didn't say oh why did they 
break their side
because that is what you know twenty twenty twenty twenty twenty one 
there are an awful lot of websites that have broken themselves
just look at facebook
and twitter and to
everybody seems to think right now is a great time too
redesign and make your website suck so
if i am forced to redesign my website i don't want it to be one that is 
being redesigned to suck i want it to be one that just read redesigned 
and actually better one thing i have noticed even just in my own little 
testing well working on other things is that the new server is a whole 
lot faster than bigcommerce ever was because its not going
through a cdn and its not loading hundreds of kilobytes of javascript 
on every page which is why it needed the cdn
pretty much instant response and i mean i have a
fairly fast internet connection but its not swedish fast so
i figure it'll
it should be a noticeable improvement in speed for for visitors and 
that counts for something






on




























alright
that's the last the resistors on the last of the boards
so i think then i'm going to probably leave it
at that for tonight's stream
i don't know what i'll be doing by monday i'm hoping to actually have 
this project finished by then i might possibly do an extra stream in 
between but i'll probably also be doing some work off stream
because i would like to not drag this dispatch out the way i did drag 
out the last assembly batch i did on stream
i
i will say thank you for tuning in glad to see a slightly higher or 
i'll actually significantly higher viewership this stream than than 
last i guess i guess you know
board assembly is more interesting for people then then web design was 
but they both need to be done
if you haven't already please remember me to follow on on twitch 
because i'm currently at forty eight and i'd like to make fifty and i 
hope you enjoyed and thanks for watching
yeah hm
yeah hm
