hey mailbag fans welcome back it's that time of the week again it's mailbag
Monday starting off as he's tradition with a beer and I'm going a little bit
out of my comfort zone on toe logger this time Redruth lager is brewed by
Fort Garry brewing in Winnipeg and it is commemorating or something or
cooperating with Salsbury hosts restaurants which are a local chain of
here in Manitoba mostly in Winnipeg of basically 24-hour diners they became
really popular because they were the only place to get food after the bar
closed for years and years and years it's I don't know it's one of those
things if you're from here if you grew up with it it's great there pies and
baking is actually really good the burgers are there diner burgers you know
but it's one of those local things anyway see what I mean about this is
nowhere near my normal comfort zone you can actually see through this but in the
interest of supporting local causes I
shall have this
yep differently lager definitely not malty or Stowe tea and I can would
normally have but as a summer beer that wouldn't actually be that bad
all right thing the first plastic sheet and plastic sheet grab the knife
first try thanks Marcel good idea okay let's see what we got in here yeah I
want assortment of things cool some more of these mini bread boards wait they're
not the same as these other meaning bread boards of god they're medium sized
mini bread boards well they still fit on the little backboard thingy yes they
will oh wow okay so to add to my ever increasing
variety of sizes of bread boards because you can just never have too many bread
boards and too many different sizes seven pieces mini 55 points breadboard
sardos prototype plus PCB adapter board ass I started maybe I got seven of them
currently they're selling for 319 I paid 316 for them from superstar
whoever that guy is I don't know from China free shipping yadda yadda and it's
little bread boards I could have bought them with an extra base but I didn't
need an extra base has already got the one you see
and also in the same package from the same seller what do we have here
okay connected oh yes ma'am USB connectors okay so say solder on to
those I guess they are just your standard USB connector I could probably
use them on a board too or I can use them in cable into mode
like this that's interesting I know what I was thinking when I bought that still
that's pretty cool a whole bunch of those P well 10 pieces type a us before
pin female socket adapter connect your plastic shell cover ass again from
superstar cuz of course it came in the same package no or 68 for the 10 on film
and these where's my note these only took 24 days to get here that's
surprisingly good okay next thing in it is it doesn't see what it is
electronics quantity one that's what it is
sure well wrap whatever you a couple of modules for modules two modules okay so
what do we have here we have you have an out plus and minus we have an N plus and
minus we have an adjustor get a capacitor at each end not three and
doctors diode diode and the brains is an Excel semi Excel six thousand nine one
so I guess I'll have to go to the listing I'll find out what that is but
with those two inductors there wondering if this is a combination
buck-boost two five ten pieces boot boost buck DC adjustable step up step
down quarter XL six thousand nine module voltage I bought two of them for three
seventy one singles go for a buck seventy one from satisfy electronics why
didn't put voltage five to thirty two volts why don't put voltage 1.25 to
thirty five volt with automatic buck any voltage can be arbitrarily okay for amp
MOSFET switches at 400 kilohertz so it shouldn't create too much noise what
else
input current three amps max output ripple five hundred or 50 millivolts
that's not horrendous that's not too bad at all
with no load it's only drawing 18 million amps yeah not great for battery
backup but you can move with that and those took pretty much exactly one month
to get here yes you should see what this thing can do huh 5 volts coming out of
my own power supply over here this power splay a lot of people ask me actually
the box I made myself and just out of plastic there's a video way back if you
look about a year and a half ago I'll link it if I can remember and it's being
power inside it's just a buck converter that's capable of constant current or
constant voltage and it's being fed through one of these little things that
I got in the last post bag from just a laptop power supply nothing fancy it can
do up to about 2 amps and yeah it it's maximum voltage is whatever my power
bricks putting out which is thinking 19 volts and it can buck all the way down
to almost nothing anyway that's an aside so
volts coming over there this is Sun split these the right way around shall
we and get out of the way the meter so you can see it's at 13.7 right now and
I'll wind it all the way to the top and all the way to the bottom okay there's
the top forty point one volts let's pin it down to the bottom still with the
five volt input
I think we bottomed out there 1.27 volts that's pretty cool so it doesn't really
matter what your input voltage is anymore
I like it alright next a big one Ankur five pack power Olli okay I think
if I remember correctly this is some USB charge cables
I think super well packaged well yeah that's like massive bubbles and we're
still a little squishy yeah anchor charging e central's oh wow not
happy okay five charging cables - of that length - of that links and one of
this phone it says right down there Oh point three meters point nine meters and
1.8 meters well that's great I suppose I'm gonna have to pull up my
little test jig and just see now the reason I ordered these if I remember
correctly is that the the power lines in them are not as like a wire they're a
much heavier gauge wire then your typical USB charging lead like these are
a dollar store ones or even you know these that's the other connector but you
know and if you remember from my my test that I did a few months back most of
them really suck the only ones that didn't suck horribly are the the
brand-name ones that came with with the Samsung and Blackberry phones so let me
go and find the listing for this and while I'm doing that I'll set up my test
jig that I had set up before and we'll just run these guys through the paces
quickly Anker 5-pack powerline micro-usb durable
charging cable 1 foot times 2 3 foot times 2 and 1 6 foot first Samsung Nexus
LG smartphones its Android etc the current price is 20 69 but when I bought
them I paid 1099 so shop around take your time you can get stuff on sale and
here's what makes these ones special they've got some reinforcing some in
them to make them a lot stiffer and stronger and they've got really thick
conductors there it is there 30 gauge data wires superfine and 20 gauge power
wires Oh a 20 gauge positive power wire and an 18 gauge power wire and sheathing
so that's super duper thick compared to your average one okay here's the same
test setup as before I've got exactly 5 volts coming out of the connector there
if I can measure it the 4.99 okay I've got my 1 amp
load here and let's just try these and expecting the short one to be able to do
it with no problem at all so we'll just
connect him on there this guy jumps up to just a hair over 1 amp expecting good
things 4.75 so that's a quarter of a drop across that wire that's better than
most of the other ones if I remember correctly I think what was my best one
for point one of the best of the cheap ones was four point four six that's
pretty good what I'm really interested in though is
seeing what the super long one does okay so we're drawing 1.08 to amps according
to that guy and getting here four point six nine four point seven that's pretty
good that's not much of a difference from the longest one to the shortest one
I'll take those and actually one of them is a boat to become my permanent one to
power my camera while I'm recording here all right next we have PCB board printed
circuit board board yay Auto translations it is though it is circuit
board oh these are some little single sided copper clad boards because I have
seen several people itching boards on their own lately big Club does it
occasionally couple other people I can't remember who you are I'm sorry
some you might be watching but using I've seen people using not the
traditional ferric chloride but some other chemistry's which aren't quite as
toxic and are easier to dispose of and more importantly to me and my cheapness
gene they're cheaper and easier with the demise of the local electronics shop
it's getting harder to find ferric chloride locally and because it's a
hazardous material it's expensive to get it shipped or at least from any place
that I found so I'm eager to experiment with some of these other chemistry's
that these guys been playing with and see if they work 10-piece one side
copper clad 50 by 70 by 1.5 millimeter single PCB board glass fiber so this is
like it says the fiber type not the phenolic resin impregnated
paper type and I know that there is some kind of there's a designation fr
something and fr something else I can't remember that kind of crap I'm sure
somebody's gonna point it out in the comments and that's cool but I'd rather
think about what the material actually is then some code number anyway I
digress this is from IC station and I paid four
dollars and seventy five cents for it and the last in we have something with
its lies covered up from Kyrgyzstan though the hats interesting I'm pretty
sure most of the stuff that I order claims to be from China so that's kind
of micro brush disposable micro applicators uh-huh in yellow fine okay
just like it says on the box now then I actually have some of these from that I
just got as a sample pack from years and years ago back when I was still actively
modeling before model making that is not actually modeling but I never bought any
despite thinking they were pretty cool because they're horrendously expensive
for what they are they are a teeny tiny little paintbrush or lubricant of
application brush things like that and so okay I got a hundred of them in here
in this cool little dispenser that's neat and I'm guessing that I paid a lot
less for them than the brand-name ones one millimetre touch up pink micro brush
100 brushes small tip s micro applicators from a sheikh who I paid no
I didn't pay for 15 I paid less than that I paid 394
he's currently selling them for 415 for 100 of them and currently shipping for
18 cents which I didn't pay yeah not much to say about them they're one
millimeter diameter ballhead small tips plastic yellow so that's a hundred of
those for that the brand-name ones are somewhat more expensive especially if
you go to Amazon CA where are they here they're seriously well that's a 400 pack
okay so still that's ten that's pretty much 10 bucks Wow so that's why the
cheap knockoffs from China see it says right there Shanghai China even though
the package said it came from Kyrgyzstan or some place like that Wow and here's
today's meal big Monday haul these micro brushes we just looked at the slightly
larger mini breadboards those are cool the USB cable ends or just ends copper
clad board for etching these two buck boosts those are gonna be handy and I
think well maybe the stereo or the good deal anyway because this was like ten
bucks for five cables two bucks each you can't much beat that from the dollar
store except for these are good and the ones from the dollar store or crap oh
you know what I've been slacking on telling you how long these things took
to get here these things one month the buck boosts one month the micro
brushes were seven weeks the SD connectors and bread boards were 24 days
I think they win the race this week and the copper clad board was five and a
half weeks so there you go I hope you found that interesting amusing living
vicariously through my my buying cheap crap that's all cool any comments or
questions or Corrections down in the comments as always and as always a
special thanks to my patreon supporters who helped me not go bankrupt buying
this stuff even though it's cheap stuff you know it adds up over time thanks
again for watching I will talk to you later
