i
good afternoon welcome to my scheduled stream for monday june seventh
see if i can get my lights not to interfere too much here
so i have really been spending a lot of time recently on this usb host 
project because its really interesting but it doesn't make for 
wonderful tv and also i am kind of at a stopping point and i've got 
other things that i have
the work that i really need to be doing now so i am going to set that 
aside a little bit i recently ordered some new test equipment for 
debugging a usb connections and i'm hoping that that will make some of 
the issues facing a little easier to deal with and in the meantime 
while i wait for that to be shipped i have
got a whole bunch of modules to make now i mean i'm pretty i'm pretty 
much ok for stock for my assembled modules but if i'm going to be able 
to s r baker says he has conflicting meetings so he'll be in and out
appreciate you when you are in and you can watch the video d later 
anyway
yeah so i spent all that effort on making custom panels and now i'd 
like to be able to sell them and if i'm going to be able to recover 
anything like the the money that i spent making those i think i pretty 
much have to sell them as part of assembled modules and all my actual 
stock assembled modules
of course have their own panels and its a real pain to put panels on 
and take them off and that puts wear on the threads and there's always 
the risk of
always the risk of over tightening things yes as our baker says he saw 
the word naked and had to tune in i think that that's what you need to 
do to get
real real viewership on on on twitch is nudity into pandering so hello 
to you and hello to a page and what we are going to be doing today is i 
went through the list of panels that i have i think that the ones that 
are
going to be most popular are going to be the ones on the middle path
and the leapfrog
and
the qoyllur
and i don't know if i'm even going to be able to sell the ones for the 
octave switch but i would like to have an octave switch module ready to 
go the idea is that i'm going to be making modules here and i guess 
i'll have to use one of my spare panels for alignment but they're 
basically going to be modules without the panels and then when someone
orders a
orders a module with a custom panel i will put on whichever custom 
panel they choose and i'll have that ready to go i'm probably also 
going to have to warn people though that if you ask for accustomed 
panel one there may be some delay if i'm low on these naked modules and 
so on i really have no idea how many are going to sell like that so i 
don't know
how much stock i need to build up but i've printed off bills of 
materials here for a total of let's see one to four
six or seven modules and i'm going to start by counting our parts for 
them and its really warm in toronto today and i don't really want to 
be running a lot of time with my window open and defeating the air 
conditioning so i'm going to try to do as much of the stuff that 
doesn't need a lot of vin
isolation first as possible before i proceed onto stuff like soccer so 
let's do that msk or eight first i have prepared
bins here with the
the
modern marvels on there
and i'm going to have one bin for the making just one of these modules 
i'm going to have one bin for the board and one in one bin for the 
cheap boy too

oh
and i'd probably better replace the masking tape on my a
multiple phone cable here
the microphone has just a little thin wire that goes to the actual 
microphone but then the much more substantial cable that's in the 
junction the preamp for the microphone is actually in this black 
connector here so i i taped that to the table whenever i'm not to
up and about because i don't want it falling off and landing on the 
floor and then the all the string goes on the microphone cable itself 
so actual ceramics

this is my chance again too
use up some of these ones that were bulk in the box
and it looks like i can even use up this entire box because there's 
four needed and that's how many were in the box
so although i'm not doing it on stream i am excited about this usb 
project because this morning i for the first time got all the way 
through the the configuration phase of the year
usb handshake when you
plug in a
a device there's this whole thing where the host interrogates it and 
tries to figure out what kind of device it is
and it was one thing after another including i think that i found a 
buffer overflow that is the fault of my hardware

tomorrow are these for the
other board there
i'm not sure what i can do about it if i give the hardware a buffer 
that is big enough and then it writes three three bytes after the end 
of the buffer
except just make the buffer that much longer
and if i can be sure that that that that three bytes is the limit then 
that's no problem
i'm programming on a very limited microcontroller but its not that 
limited basically and these buffers are on the stack
so its not a permanent loss of space
okay so i also need a thirty three puff ceramic i think those are the 
spool in the back but
just check here if there
iranian here no
so yeah i'll have to get those off the spool
check here
sorry i was just a little confused about what was in that bin that i 
saw my
bench there
okay
hundreds
thirty three
and i need to have them



the first device driver that i'm writing for this
usb host is one for a mouse the idea is going to be that you can plug 
your mouse in
and into the
the modular module and then the two control voltage jacks on the front 
represents x and y so as you move around you are
you you're adjusting the control voltage there and then
then when you click it'll send a gate so you can have a
you can control your your module are there at least one voice maybe two
just by moving and clicking a mouse i think that will be sort of neat
i
and the idea of modular controllers is
okay so this is board one
or to some that something that's kind of a whole both in the market and 
in my product line
so it'll be something that'll do
good to have i don't really see that as the main
the main application for the module the main thing its really for it 
is an interfacing like a midi controller but ah
the mouse is relatively simple usb device
probably a good one to do first and it is also a cool little extra 
feature to have in the in the module
okay
these general purpose diodes
twelve of them in this bin two and four in the spin
the
the shack is
the two are these four room
reverse power protection


the member at one point
i had set aside some bins that were partly counted out for this project
because i'd accidentally prepared more than i thought i actually 
intended to make i think i already resolved that so
i am going to starting from fresh on here
in the early days
i have different ones including some that look the same like there are 
a couple of different at least by color lcd ones
with different to current capacity so it is kind of important to know 
which of these ones here are the ones for the msk boys so that's fine
and they go on board one

no
why am i seeing
standoff son here twice i guess i must have when i was writing this i 
was not absolutely consistent since on these sheets i listed all the 
parts that are used in preparing this even though some of them are then 
used a second time later in the build
maybe something i want to look at
i




all of these
of the some documents
are open to revision over time
now i need the standoffs for the air
to each attendant eleven
tens
tunes elevens










and i'm going to need to reach screws and nuts


if i can find the tagging here that's open
here we go












ah


here is a chance to use up some of these parts from this bin that may 
be why i thought of it earlier
see this is a twelve pin low profile socket and there's nothing wrong 
with that it can go on the board but its not the kind i usually use so 
when i bought these and realized that was what what i had
i decided to set them side and only use them in
my own builds
so that i can ship to the customers who buy kids ones that look exactly 
like the the photo
sorry
now and because i the twelve pin ones are only used in this module and 
this is not my most popular module
those those twelve pin low profile sockets have been sitting on the 
shelf for a long time
so now's a chance to use up one of those and one of the matching males

and let's put in a
power hitter as well and we've got those out




eight panel jacks
true

three
six
there are six more for eight


yeah the trimmers
one vertical multi turn one k

these and i'll also need to vertical multi-trip fifty ks

its
nice
let's get this out of the way
current

stab myself just under the fingernail there
yeah that's the one k

hi



that doesn't seem very secure attachment cream butter but they haven't 
fallen out yet so it may be ok
the and then we're onto resistors
the nine ten one
think these are used for
current limiting the only genes
if i remember correctly i had to do a fair bit of calculation to figure 
out just what size resistors i wanted on the ladies in this module so 
that the grid in the green
would be at roughly the same brightness
that's a complicated question because the human eye is not equally 
sensitive to those wavelengths
and in any given by color lcd
the red and the green sides of it may not be equally sensitive to 
current either
so i had to do a bit of experiment to figure out just what current 
levels i wanted to use for the two the two sides in order to make them 
be about the same perceived brightness
what i'm doing here is looking for the end of this tape
its not easy to find
here we go
ninety ten
for those

trying to put this back together in a way that'll be easier to see
untangle next time i go in there
i love commander root
so then once i knew the current levels i wanted
ah
in this module all the the thing that sets
the l e d currents or or that drives the ladies is basically the output 
of
contrary to chip the shorts to ground in one said not in the other so i 
had to figure out a network of
resistors that would put the right current through the lds in both 
cases and i think that was one where i ended up actually optimizing it 
using prolog
because i worked out the the formula for how much current would go 
through in the high and low states based on the resistances and then
spent
and then had to iterate through different choices of of the resistor 
values from standard standard choices hello to surplus d and thicker
i bet
because there are only certain resistance values that are available as 
standard right in with like three
resistors in the circuit
why did i cross off one point eight k on there
shouldn't have done that
and they all affect each other
so although one could probably solve it with algebra
it was easier to just effectively simulated
one k goes in there and then
i'm going to skip ahead and do the one point eight case so that what i 
wrote here will be correct
its in the same bin
as these others anyway
one for the key





alright and also in the spin one point two
oh
well i have this one one k resistor here that i probably should have 
used up taking the opportunity but
not really an issue
one point two
hear here
couple of one point two so i called earlier i can use those
no


alright next is two point seven














and six point eight k











revolution put that away because i care i am going back into it i need 
the eight point tos
four of them
a lot of these resistors are in the older packaging here because
this was one of the first modules i started sewing
solid parts that i bought specifically for it and some of them are not 
actually used in any of my other products
those i have packaging from the early days
hello academy impossible
i'm never quite sure with some of these names i see joining the chat if 
any of them are bots but
i generally err on the
side of greeting people even if they do turn out to be bots i mean i 
guess bots should be thought of as people too
robot rights represent or whatever

forty seven k









seventy five over on the other side here


basic principle when i have more than one container of
item like this is that i take from whichever one has the fewest
because that way it will continue to be the fewest and it'll run out 
sooner
and in practice that usually means i will end up getting
something close to first in first out
which seems a reasonable way to use up the oldest stock first 
theoretically its the way i handled my inventory for accounting 
purposes its on the assumption of coke costs are first in first out
although i may not actually work out exactly the way for some reason i 
acquire just a small container or something
which was the case for instance
with those phone jack sockets because
these clowns and
newark for now element fourteen whatever
i
they like to ship me all the ends of reels and bits and pieces of 
leftover whatever
so sometimes i get to
like a bag that has three attached to another bag that has nine hundred 
and ninety seven according to the label
that kind of thing
also i make exceptions when like i have a bag of parts that i can't 
hear this is the one i should draw from instead of this one
if i have parts like those low profile twelve pin connectors that
i can't use in the normal way
then i'll use those wherever i i can use them
so it seems it up again








wrong been there
so right



inspec is
not in great shape
its still on my list to try to figure out something sensible to do 
with the
all these empty packs that pile up
i can't really use them while they have stickers on them so any that i 
am going to reuse i have to remove the stickers
i was thinking that might be a good use for some of that to 
butoxyethanol i wouldn't be surprised if although plane as appropriate 
alcohol will work ok for removing the stickers i wouldn't be surprised 
if adding mixing in some of that stuff well
it'll help it to dissolve secret glue
and that would be a good way to use up what i now have a substantial 
oversupply of
but that would also mean i have to re
restock those natural light gloves which i am
basically used up exactly the box on the panel project
no
its time for the famous precision resistors
poop says i just use markers to write on top of a stickers that's great 
when you are using them for your own use but the main use i have for 
little bags is in
kits that i sell to my customers and for those i want them to look nice 
and i don't want information leakage of all the details that are on the 
stickers and so on to be going out there i would like them to have no 
stickers on them so i think if i'm going to use them in that 
application i need
to remove the stickers
elise
i don't think this will show up on camera
but its sort of interesting that on these precision resistors normally 
on the tape the resistor code all reads one direction on this its its 
back random write these to read this way this one reads this way this 
other one reads this way this one reads this way here are two more that 
read this way i think that what's going on there i
doubt that you could see it but it may be worth a try
i think what's going on there these are the ones that are zero point 
one percent precision i think a signify they the way they manufacture 
them they make them and then test them to see whether they're within 
spec i think maybe a significant number of these ones are not in spec 
and so you know it also may simply
be that they manufacture than the manufactured one is going to have 
been there loose and then once from there bien get drawn back into the 
machine that puts them on a tape or something so that they end up in 
random orientation
but its not something i usually see with resistors usually they read 
the same way all down the tape


alright and now the one hundred k precision
i've got that big box down there of
one hundred k regular one percent but
these are the fancy ones that go in the
in the octave switch because these are part of what determines its 
accuracy

now these ones even though they are also precision they
read the same way all the way down the tape
so i guess they didn't go through the same process



yeah when i am just reusing a bag for myself
i just write on the tape on the sticker

but i i only have a use here locally for
a few of these
most of them if i'm using and then reusing them at all it'll be for 
outgoing
okay so now i need two switches
and then we get into the more serious semiconductors





huh



notwithstanding the
controversy about what order to put the hardware onto the switch one 
kind of nice thing about putting it all on the outside with the 
customer panels in particular is that then something like this locking 
ring can hide any little imperfections around the in the finish around 
the edge
edge of the hall
because especially on the debt on the
hendrick graphics panels
they don't always look good right next to the hall
so if that area of the panel is covered by the washer its
probably good for the overall fit and finish

given that with these little
many switches there isn't like a what on some bigger switches would be 
called to address nut
a cosmetic thing to make it look nicer there

the
the think i will leave the chips that don't actually get soldered in 
for later
oh yeah
and the next i'm going to need
voltage regulator or two




and then its just sockets on these lists although i guess i should 
also include pcps


putting the date on there because it may be a little while before i get 
around to actually entering these sheets into inventory
and i will want to have the right dates on them
okay
laughs



wherein there
chilling there


and then its just the circuit boards

if i get rich there
oof
i bought these boards when i
thought i was going to be selling more of these modules than i actually 
did so i haver
larger
large collection for oid board
basically a lifetime supply there
which did mean that i got them for cheap although they're not cheap if 
i don't end up selling them
but at least it means i'm
spirit concerned about this continuations
nearly all of these modules that i'm
working on today
alright so these ones are basically done
you can set them aside and start the next nearly all these modules that 
i'm working on today the qoyllur or the leapfrog middle path
use this
elam thirteen seven hundred operational transfer conductance amplifier 
chip
and
mid-may texas instruments who makes them announced that they're going 
to stop
that's an issue they're not taking the chip itself completely out of 
production they are
if they're stopping packaging it in dip the that you know the
dual in line package through hole package for
for chips
which ah
is the form that i want to use them in
and
they're are only going to be making surface mount
so after some
debate and gnashing of teeth
i ended up doing a lifetime buy i bought
as many of those as i think i will use for the
useful life cycle of of the products that use them
and i have those now so
even in the event of further further issues
and even if the supply chain goes further for fluid than it already has 
i am good for ellen thirteen seven hundreds
but the synthesizer hobby as a whole is going to have to
figure out how to do that how how to
either surface mounted them or use a different chip or something
and that was basically the last of the through-hole operational trans 
conductance amplifiers now there are no no more chips of that kind not 
even that specific model available from major manufacturers at all
and her friends in latvia
by which i mean a gertz of erica synths and alpha corp which i'm not 
clear on whether that's his project or if its just one that he is 
connected with or if its his buddies or what but anyway they are making
revivals of a number of old synth related chips in particular the ca 
three to eighty which really i don't know how their revival version is 
i think it doesn't have the original specs but the original one was 
actually better than the thirteen seven hundred anyway
that was like the premium
ot a chip
ah and its been out of production for a long time

i gather that the way that worked was that in all the former soviet 
republics
when the
when the soviet union collapsed
the military came through
all this semiconductor manufacturing was connected with the military in 
soviet days so the military came through and went into all the 
factories and took out everything that they considered secret and then 
they just left what was left of the factories so those factories fell 
into the hands of private enterprise
and in latvia in particular some people managed to dust off all of this 
equipment that is by most standards obsolete
by the standards of the west the russian system was obsolete anyway but 
its even more so today
but they they still have the tooling that it takes to make some of 
these old analog chips
so
with the this repurposed factory that was basically abandoned by the 
soviet military after they took out their secret things
they are they're using that equipment to make old fashioned style new 
manufacture of chips like the thirty to eighty
i'm going to do the smart thing and remove some of this extra tale of 
them
paper tape here
so that's kind of cool
and its a project i might like to support but i'm not sure that i 
really wanted depend on it as the source for
for a critical component that used three of my major products







and its further incentive for me to keep on developing new products
like the usb gadget in particular and planning to call it the gracious 
host
think that's a neat name

oh i got so into them
the idea of building just one module with as i was for the oboe eight 
that i forgot for this i need to have it everything
so back to the schools
this is the one hundred puff
huh



the
the
the okay now the ceo appointment
the two in each of these and four in each of these
two
true
four
info

the
the
the
the film camps too
and
two

the
the sort of the usual power filter stuff
though nearly all of my modules end up containing at least two of these 
electrolytic for room power filtering
a couple of
schottky diodes for reverse protection and so on
the

and here are the schottky diodes



the coils

hence the name quaker



basically the
this module that sells itself on the strength of coils are cool
that's pretty much the design concept
and they do have some disadvantages but there's they are cool they they 
sound interesting and
its an unusual thing people want to buy a thing that has a story so 
with this the story is that
core conductors are rarely used in audio and

sort of
its a different kind of filter








the tape on
diodes here
doesn't accept the ink from this pin have to use a different one for it





senior diodes
four point three i forgot where they put the four point seven i think 
they're in here
yeah

huh
these ones call for caution because they look exactly like those 
general purpose diodes i just handled
yeah
there are nearly microscopic numbers printed on the barrels of the 
diodes
and its not terribly difficult to test them electrically to figure out 
which are which but
preferable not to have to


if you do want to test them electrically what you do is you take a 
power supply at a somewhat higher voltage like baby ten or twelve volts 
for this in series with a decent size resistor like ten k and then you 
apply it reverse against the the diode of a z
learner drivers will break down at that voltage they're supposed to 
that's what makes them zener diodes and then you can measure the 
voltage across it and say oh yeah that's a four point seven
and the general purpose diodes are supposed to resist reverse voltage 
or block reverse voltage up to at least fifty volts
and you don't want to exceed that or there'll be destroyed so if you 
don't if you see the power supply voltage across it
then you know that you're dealing with the of the of diet that does not 
break down at that voltage
and if you see something like sip zero point six sports then you know 
you've got the diverting backwards is forward biased but in that case 
the resistor will be preventing it from being damaged
so not a terribly difficult thing to do if you need to but
better to already know what kind of you you're looking at

nuts







alright this one takes eleventh and thirteenth

was it the thirteen's
the blevins



i
the screws are next


hmm
yeah
huh
thought for a moment there that i had screws listed twice on the list 
but no its machine screws and nuts four machine screws
so two different items




and once more into the pile of
jack sack its okay for this project i need seven of these so here's 
four and three more
should leave me with seven on this chain yes

i have this other bay here in which they're just loose which is 
actually nicer to deal with
but again i use the ones that are kind of worse or more annoying first
so then i can spare my customers and my future self having to deal with 
them
and i mean
i should speak carefully there that jack sockets themselves are 
identical its not like there are good ones and bad ones its just that 
the way they're packaged individually like this is an annoyance

okay
power hitters i always did that

i need
one of each of these forward to port headers
per module




this is actually another issue for reuse of bags is that these 
suppliers use basically the creamiest bags they can get away with and 
they they fall apart so
i have to look carefully at each bag is it in good enough condition to 
use and
is it a good enough quality bag for my purposes




alright now
now we're gonna use i guess some of these last few p n two hundred days

is there some of the discontinued parents
i have to replace them with
a different high gain pnp transistor said tx something
i forget the number although i'm sure i will end up memorizing it
you saw me in some of my earlier streams building prototypes to test 
whether the the new transistors will actually work and they will
there's somewhat more expensive than those p n two hundred days were 
though
but that's the march of progress i guess
alright until the resistors





again using the ones from the smaller container first

these ones are nicely rolled up










now the one case and i will remember this time to use this one leftover 
one k
cause this is a quick moment to do that
huh

and then i need two more for the first binge
three more for the second









one point eight k
shouldn't have put that away
needed it again almost immediately

















yes this one
but i did make the effort to keep the end hanging out here so i could 
easily find it again this time









nine point one is next







nine point ones i actually have on a spool back there but suck
i've been taking i took a chunk off the spool and stuck it in this bag 
for
easier handling




















eighteen k















twenty two is next
lie here
this one's a real price its like bringing coral in there

huh
here we go

it was relatively easy


huh


i do wonder sometimes what goes on at the distributors how
these packages of different components get into the shape they are in 
when they arrive
at my location
you know why do they have a little bag that contains three attached to 
the other bag that contains nine hundred and ninety seven or
you saw the fancy packaging that those precision resistors were in
cool wasn't made the decision that they needed an anti static box for 
resistors
i dunno
so the anti static box becomes another item that i don't want to throw 
away because i know its worth something but i don't actually need very 
many and aesthetic boxes so
once its emptied it sits around











she grabbed the twenty seven kate while i held them out


three
twenty seven














fifty one k
what's next

fifty one k there
see if i have any others
i've got three bags here labeled seventy five



the
the





okay two of the hundred k fixed resistors and
in five in the other ones i'm having to
check and recheck there because there are a couple of other things on 
the list labeled hundred k

seven there for the two boards
another seven
in addition to these there are going to be like parts and tremors and 
stuff that are also valued at one hundred k so
have to keep track of which is which on the list


yeah two in there and five in there



five

no
guess i'd better go and grab the
panel parts
which are over here off screen although you should probably still be 
able to hear me
i can have to lower that mike to the ground there

alright
counterparts parts in there

i don't seem to have a whole lot of those somewhere
that may be another thing that goes on the reorder list
laughs



yeah i'm going to make a note that five remain

those are going to be expensive to reorder too
though but if i have to i have to
alright let's see these
i guess they do
i know
i couldn't even remember these gifts
lock washers are just spring washers now i think they only get spring 
washers here
peering at my ear
my ones synth in the background there
they do get lock washers so i'm going to have to dig those out of a 
different bin i guess
huh yeah these these picchu sixty ts take the same hardware as the p to 
sixty ps so in the past i have sometimes folded over the wrong bag and 
that means then i ran out in one bag and i have to pull it out of the 
other peg
i have to stick my mic cable as well to get over here
alright
yeah okay so
off
this
three

aha
they were both large and a small bag of those in the bin so i think 
what happened was i just put the
small bag from the small supply of teas into the bin with the large
larger bag for the be the ps
you know the
tumultuous rise and fall of monday afternoon here where to put my lock 
washers


oh well i'll tell you where you can put your lock washer
which as as i've mentioned with the
toggle switch isn't even always an easy question to answer


okay
spring washer lock washer nut
that's the
lineup four for this kind of pot










all these that i throw down here now i'm going to have to earn thread 
later when i assemble it but i still think that doing it this way is 
what i wanna do if i'm not going to be building up the module 
immediately which i'm not because i have to count out all of
these bins full of stuff first before i start any of them or that's my 
plan anyway
so inserting a full set of hardware onto each part here just to make 
sure that each part has its exactly right set of hardware

and keep that true across however long delay there is between when i 
counted out when i actually use it

these pigs here are some of the nice ones they're are small and useful 
for components
and they don't have stickers on them




okay
no arm trimmers

one hundred k trimmer horizontal single turn
i'm trying to move more towards using a single term trimmers they're 
easier to deal with
there a little bit cheaper although not as much as you would think
huh
this bag has not yet opened so maybe there's an open door and i can 
start with
the
yeah

the
usually these ones are blue but this time they were white or grey
it depends you know just exactly which manufacturer i ended up getting 
there are a couple that are considered basically good
burns is the brand name but
the burnt parts have become overpriced because they are the brand name 
more often i end up buying some that are vishay brand
palm which is still pretty good
and the chinese knockoffs are often like if you look really close you 
see it says bones or boons or some other something that you could 
mistake for burns if you were were not looking carefully i'm not sure 
why the knockoff manufacturers just
just don't write borders on there
its not like they're going to be facing any meaningful consequences 
for trademark infringement
but
and sweat when it when you look at the pardon it says bones and you 
know what they're aiming for
its a joke really but that is how how they do it



i'm sure there are some counterfeits that actually do purport to really 
be burns brand
but there are probably more
that are knock offs with a name that's close




two of those in each bin
so i need a couple of a few more








two twenty two twenty two twenty two twenty
panels before i'm going to skip over the
the pisces which in this module includes one of those famous selling 
one through seven hundreds

and there were then we're onto the dip sockets
two fourteen and sixteen
the fortunes first


fortuna fourteen
fourteen


yeah fuck are these the sixteenth
look for sixteen


the elam one through seven hundreds are basically the only chips i use 
at the moment that are sixteen pin so all of these sockets are for those



just started
when i should have gone for that first



sure sockets are packaged in the anti static rails unless its just that
whoever is shipping them only bothers to even keep anti static rails on 
the ground
which would make sense finding similarly i only have a stock of anti 
static bubble wrap even though a lot of the things i use it for don't 
really require that
okay so that's all those components except for the piece of bs



nice pcbs are packaged a little differently cause they're from india
and i think the indian manufacturers still working out their procedures 
because it comes through a little differently every time
just fine
in this module
somewhat unusually the two pcbs are not the same size
the one on the back is a little smaller
they still line up at the mounting holes though so it works
and there came about just because i needed a certain amount of space on 
the front one for
the panel components and then i needed to have a back one at all 
because i didn't have enough space on there for all the other stuff but 
then the remaining components that had to go on the back were not so 
many as to require a full sized board so i made it a little smaller 
which makes it a little bit cheaper to manufacture


alright

that's all of the
parts prep for
the one nines

so i can get these out of the way and then proceed to the oil sevens
which are more complicated to
build
three boards and the all seven

two three




alright now
of tear and
axial ceramic camps
radial ceramic twenty two pamphlets do ceramics first
those in a moment
twenty two
i think these are going off screen but that's okay you can see my hands 
move anyway
one in each of the board one bins

and hundred
those i'll have to get off the spool










then until the famous
zero point ones
tune board one two and board one seventeen in each board too
solids
four
eight

twelve

sixteen seventeen


four
eight
twelve
sixteen seventeen




electra lyrics

two in here into me

huh
two
and two
two
and two


the credit on there
to put a pin there
the film caps
the zero point four my preferred

there's going here

didn't i say zero point forward zero point four seven



okay now for the
fancy expensive for seventy puff polystyrene
integrated
its interesting you say that most people polystyrene the right cheap 
plastic foam
but in fact that is the preferred material for a fancy audio caps if 
you're not going to honey two up
beeswax




so five of those in there
this is another item on which i'm a little low
i generally keep less stock for the pricier components because
takes a fair bit of cash to buy a bunch of these and also i don't want 
to have a lot on hand if i don't end up selling the modules made from 
them

you pay less if you buy in bulk but its not a bargain if you don't end 
up using what you buy so
its an eternal questioning measure managing a small business its 
weird what size orders do you really want to make



shocking and regular downloads
shock he's ever been basically every product i make and regular regular 
diodes are most of them so


















okay
this one
i need four point seven and six point dogs
these are meant to provide a bit of distortion
on the output
that's supposed to be like really gentle distortion so as the voltage 
goes up the first it hits the four point seven and those roll it back a 
little and then if it keeps going up the sixth point always come into 
play

but it does mean that on that board one
i have six diodes of three different kinds that all basically look alike
so it does call for caution in assembly and labeling












the right hardware time
standoff screws
yeah more screws or stand offs do
let's do the standoffs first


curtains and thirteen's

and elevens
eight of these in each module
these are another thing that people don't understand that they cost 
money you know these these stand officer
like fifty five sixty five cents canadian each
and i just put twelve of land to each module so that's a few dollars 
right there
but someone who looks at the bill of materials is inclined to only 
think about parts like these these capacitors
in resistors and say oh well it doesn't cost very much to build one of 
those cars we've you know capacitors and resistors don't cost very much
but those standoffs alone cost more than all the resistors in the in 
the module


she unscrews
and nuts


so i need four screws in each of the board ones


four
and four

and for nuts












okay
do those
jack sockets next looks like i have some chance day of using up these 
individually packed ones which would be nice

the individual packs like this make them easy to count but
its really an annoyance separating them out of packs
i prefer the bulk of balkans
just four left in there
huh

hitters
there are a lot of hitters in this build
first of all the
power hitters
one


mail ten pins three in here two in here permit
three
and three
did i say three and two it should be three and one and one wanted one



and the females
to match

three
three
and one and one





okay
now its time for pie and two hundred days
again
i'm like going to i think i have enough here for for these modules 
budget
getting close to the bottom of the bag there
and there won't be any more because they're discontinued so
i probably will not mix them even though that will be okay electrically
but if i have like three or four left at the end
i'll just keep them
okay so i need
eleven eleven and
one in one
total of thirteen per module no
right total of twelve per module

that's eleven there


toe in there
one in one






those ones nearly ended up in my lap
okay and three the five away dates

also discontinued sadly enough
although those
i found out about it in
enough time that i was able to do a lifetime by
actually it was a couple of years ago i have not actually dug into that 
lifetime buy box yet this is still my last my last batch from before 
they were discontinued
but i have i think ten thousand if i'm sitting on the shelf
what i hoped would be a lifetime supply
because unlike the two hundred days
i couldn't find any really good replacement
the going to spin cycle in these bins
and there we go

oh boy now and to all these three sisters
kind of putting that off
yeah actually maybe i think what i'll do on stream today is all of this 
stuff except
the little fixed resistors cause those are a lot of work into
i'm starting to be aware of how much tolerance i have for doing more of 
this stuff right now so
i think that'll probably be my stopping point i will do all the stuff 
in these accepts the resistors and leave those for probably tomorrow 
but for now
i do still have a fair bit of other stuff to do so five hundred on the 
horizontal multi-terrain
see if i had any others of those
huh
huh

really its the leapfrog alone this particular module that is 
responsible for a lot of my

yeah i kind of have a multi-terrain trimmer problem
there are let's see one too
three four ten
thirteen thirteen journalists in this build
which again is a symptom of the fact that it was not originally 
intended for commercial production
and then once i rolled it out as a product and
then a lot of people started buying it
i was kind of stuck with the design didn't want to say oh well i've 
simplified the designed to make it cheaper to build good that's not 
going to sell well
but you end up with
just the
the sort of frozen version of the the experimental thing i built for 
myself once
these are vertical and the horizontal










hundred k vertical while i have them out
three of them for the launch module

there are over a dollar each these things
saying i'm going to have thirteen of them in the module
that that right there sets
a floor under the price
but really its not even the money of buying them that's the issue its 
the fact that they all then have to be adjusted after you build it
which is a procedure i could do without
about what you're going to do
having them all precisely adjusted doesn't mean that you get a very 
accurate filter curve which is one of the cool things about the 
leapfrog filter so it they are there for a reason
what next two hundred


i was watching pulp fiction
one of my favorite movies
and there's a bit near the start where the guy goes to buy drugs
and the dealer is telling him well you know you can get this kind and 
it costs this much and its really good and you can get that kind and 
it costs more but when you use it you will know where that money went
and although i hope
my products are a little more pro-social than than heroin
that is kind of the
the proposition here when you use it you will know
why it was worth the money
okay there's the hundreds
and i need the one ks and two case

two kids that's not going to be enough of them no problem
here's the one case



i'll look for more to case in a minute

first the two hundreds

when in japan

the one case
one of these in each


now the two ks i need six for each bit so this bag is not going to be 
on it from
i didn't check the inventory count before i started this i hope i'm not 
going to run out
but if so i guess i just put in another mouser order and they won't 
really be a big deal
maybe take that opportunity to restock those some
others the the the panel pot
but first let's go through here carefully

no i do not have
i
what have i got i've got eight of these and i need twelve

so i'll have to order more




make a note here on this tape










stick this in here
so i won't forget


the that is all
that i'm planning to do right now for board threes
i think there are a few more items on there
bored ones and twos
yeah
voltage regulators

are involved and two point five

the two point five
the leapfrog in order to walk
be somewhat protected from fluctuations in the synthesizer power supply
which are often are a big problem for people it has its own internal 
regulated nine volt supply
that goes to some of the parts of the circuit that are a little more 
sensitive
so that's regulated by these these seven eight or nine seven eight l 
nines
in the first version of the bill though i actually used a seven eight 
one nine not without an l and that's the much bigger chip in the 
relatively high power package
but for the amount of power that is going through this that's really 
not necessary
and it takes up a lot of board space
so i cut it back to the elo nine and the the small package that that's 
going to need some dip sockets
as for board one
i don't have enough of the pg sixty ti pots either so that's going to 
have to be another
reorder

but i can put in with her mistress

temper temperature variable resistors every resistor response to 
temperature a little bit but usually that's undesired so they try to 
minimize it
these ones
are meant to respond to temperature in a controlled way so that 
basically you can use them to measure temperature
and then that becomes part of compensating for the temperature effect 
on other components







d p d swick d p d t switches
individually packaged again
it does make it more convenient to handle them just now in that that 
context its
a shame that's annoying later


dip sockets

these are the sixteens
three in each of these


three


three

and frequently the fourth teens here

fourteenth one in here and one in here for four

so that's one on one

these are running low too
probably candidates for inclusion in that
lazarus order

four
four









alright now
have to unleash myself to get over here

i may actually use up this first order of board sometime in the near 
future

it'll be kind of a nice milestone












alright i think i'm going to want to call it about here i have done
all of the o o eight and the one nine and all the o seven except the 
fixed resistors and a few parts that i ran out of so now i have a 
pretty clear idea of what things i definitely need to reorder and in 
order to
finish filling these bins and some other time i will probably want to 
do the all those resistors which are you know as you've seen a fair bit 
of work so i will say thank you for watching and please remember to 
follow me on twitch if you haven't already because i get points for for 
that time
at thirty four and i'm hoping to hit fifty four at the next level of
twitch special coolness
and hope you enjoyed and have a nice day
oh yeah
it
it
