Hey everybody guess what time it is? It's mailbag Monday time
And I've just noticed that this is in fact the 50th mailbag that I've done
Wow amazing, how time flies
anyway
Start with the traditional opening we have beer from stone angel brewing in Winnipeg red-handed Irish red ale
four and a half percent alcohol
When no.22 IBUs, I'm not too bitter
ingredients berry water and hops I
Already kind of did the opening a little bit
Stone angel brewing began production in 2017 specializing in easy drinking euro style beers
noise
I'm not gonna read all that you can go to the web page and read it if you want look there's a web address there
Hmm I don't like the color of that
Interesting flavor
not not super multi, you like the south supporters, but
Not crazy lightweight either I like it
All right, let's start with this guy one plastic sheet and five modules
Wonder what plastic sheet really is this time?
As it's never actually plastic sheet is it
Everybody gets stuff that oh
It's a bunch of spools of wire. Okay?
So what do we got here?
These guys call themselves
0.1 millimeter jumper wire are they all the same? Yes, they are
They look like they're enameled wire
Which means?
You can wind inductors and magnets and whatnot out of them
So if they're enameled they've got a thin enamel insulation on them, so I should not
be able to get
continuity across them and
I'm not
That's great. So
Wonder why there's Oh
looks like there's only really a
couple of layers
On the spool there
So it's not huge amounts on each spool, okay. Well that's that's something
Let's go take a look at the listing for that one and then we'll come back and take a look at this
five pieces one millimetre copper soldering solder PPA enameled repair real wire
currently selling for at over 58 or a buck 19 American I paid at over sixty six way back when so
You'll get a deal
Maybe unless the price changes again free shipping. Of course one roll of point one millimeter enameled wire
length about 15 meters
So is that 15 meters for each roll or?
divided by the five rolls
Mm-hmm can be used to connect fly line jump wire
Okay, so they're suggesting using it as bog wire basically
I suppose or I could use it for winding inductors the coils or pickups or things like that
which is I think why I probably bought it but
Yeah, you could definitely use that as bard where it's insulated
okay, and the other thing that is in here is
0.6 milliliter the finest-quality solder
64 percent tin 37% OLED
1.2 percent
Something
40 grams worth though
Just says the same thing on the other side
The high pure degree does not need though I of soldering in Queen silk
Quality first reputation first so the reason that I got this other than that's always handy to have solder around
He's oh that's nice and fine too. Okay, is that last couple of kids
You may have noticed that I've been using this monsterous stuff
Which is one point five seven millimeters 60% lid oh
This is 37% lid
Okay, that could be a bit of a pain in the ass disorder with actually
And I'd I'd lost this piece which is a little bit thicker than that, but I don't have much of it left
So I figured I'd better order some more before I complete you ran out
So that's what that is. I
Guess I should try it out. That's fairly soft. Yeah. That's what the same as that
Let's go see what I paid for it and then all fair soldering iron and
Just see how it behaves
soldering wire tin lead rosin core solder
sixty-four
1037 LED 0.6 milliliter 40 gram 1.2
unspecified units
from GC supermarket
Actually, it's currently going for 264 Ora Buckman United American. I paid 277 for it back when I bought it
What do we say down here?
Good wettability conductivity thermal conductivity easy to climb on the tin
hmm
Climb tin with good speed and a few residues no, not and winding, right?
Ah there 1.2% flux now that make sense
Okay, let's play with this solder. I've got my
iron set for about
420 or so
That melts fairly easily
Well, not quite as easily as this old solder which is probably more leaded
So I got a couple of things on here I got a
couple pieces of stranded wire and I've got an LED
down here, so
We'll do the stranded way or the standard way is not tinned or anything
So I'll do that with that solder and wait the iron tip off nice and clean and
Do it at this with this sort at the same temperature you need to push a lot more in
Okay, well that I
Mean, it's it's a little bit higher temperature. I'm gonna bump my iron up or is it now? It's
About two-thirds of the way between 400 and 450, but before it was one-third or so
So clean the tip again do this side of the OED with my ancient solder
Between the tip again do this side of the led with the new solder
Again it's taking a little bit longer to melt
So I'm probably gonna have to run at a higher temperature that I'm used to but let's see what we got here
So the two on the right of the new solder and the two on the laughter the old
Higher-ed sardars
No
It works it's not quite as bright and shiny maybe if I crank my iron up just a little bit more to 450 focus
Wow Rita nori whit those
Yeah, it's not quite as shiny is it I guess that's the higher tin and warhead content oh
well, it was only a couple of bucks and
It's Sauter's and it's not a complete waste of time
Maybe I'll pick something else up and try that too
okay, the next thing is
finding
I'm told that's a jewelry term for just odd little bits and pieces that you for making jewellery
This isn't the first time I've seen an eBay seller call it Nicole something of finding
elastic band is
This it's a bunch of little circuit boards. Oh
Okay, you know what, these are these are a little capacitive touch sensor. I
Don't know why I even bother trying to get these gently out of the bag I'm gonna put them in a component drawer
Anyway, yeah
These are these little capacitive touch sensors don't think that I've used a whole bunch of them on my railroad not that long ago
A link that video up there
It's I built a control panel for my model railroad or part of my model railroad using these guys
Hidden just behind a layer of
paper for the graphic
So that I control some switch machines
Just looking closely at them so that a and B jumper pad jumped one or the other
one of them's for momentary or
toggle and the other one is for normally higher normally low I output I think and
This pad up here is for putting a capacitor on
To change the sensitivity of it. It's a really small
picofarad value I think
but anyway
These work pretty well just ground and five volts and then the output I think was higher low
depending on what you've got that to a jumper set for
What 10 pieces TP 2:23 capacitive touch switch button self walk module four do we know?
from good jewelry
$8 97 for the 10 of them or door 49 American
and
free shipping, of course
Power, you know, it'll range between two and a half and five and a half volts
so it'll run either on a 5 volt Arduino or on a
3.3 volt thing like Raspberry Pi or
Esp8266 or stuff like that
So here's those two jumpers that I was talking about
you know, they have soft walk or no lock which is
latching or momentary and you can have either a high or a low TTL output high being
essentially VCC and a low being zero
You can choose between any permutation of those two things
Okay, next let's look at this big guy this actually was shipped to me by Canada Post from
Mississauga, Ontario
Even though the order I'm pretty sure said China
And also for some reason it says from Mississauga, but it's got a YVR code which is Vancouver
Strange. Oh
It's a crimping tool
Excellent
Got here
professional crimping tool for the best
technicians the best electricians tools
Okay
So this one is
For sleeve type terminal. Oh
is that for those feral things I
Did order one of those that's a neat way that those jaws go in
Sorry, doesn't they square krimpets? This is zoom. You know that
So it comes from all four sides and crimped in a square crimp and then it's a latching crimper
Get all the way down and then it opens back up again. Cool. I
Know I ordered some of those Ferrell's but I don't have them yet
Here's another cheap crimper that I got. And again, it's a latch. You know, it's
It's for the dupont style connectors or other small
Connectors and again it ratchets Ian. So it doesn't reverse until it's crimped as tight as it claims
that is the
specification
But this is a completely different action this one sort of
squishes it
It doesn't prayer prevents it from going sideways instead of squishes it between the hammer and the anvil whichever one a switch like that one
That before we actually pretty cool. Oh
And it's got some serration, can you see that
There's some serrations inside the jaws to
That's needed
Okay, so what happens we put some serious thickness in there
Okay, it's still
crunches down pleat tight onto them
But I think there's some kind of spring action behind. Oh, yeah, look at the
Serrations that it puts into there. That's slick
self adjusting ratcheting ferrule crimper player HCSC 8
6-4 a whatever that means
Point to five to six millimeters squared or a WG 23 up to ten wire. I
Got this from comfy lifer who no longer sells it
From him I paid 16 dollars and eight cents
This random seller that I found is currently selling it for 1744 Canadian or 1316 American
So a capacity like it's set up above
0.25 up to 6 millimeters squared or 23 up to 10 AWG
23 is nice and tiny 10 is that's like heavy house AC wiring good for
One in the 30 amp range or something crazy like that
So there's a couple of different versions of it
This one up here with 4 jaws is the one that I got looks like there is also a 6 jaw version available
So just be careful when you're ordering you get what you want
self adjusting to the size of the wire in ferrule size easy operation
Ok, and crimping pressure has been set precisely in the factory. Well, that's good to know
What is next one times driver
Motor driver LED driver
Car and driver
Mmm, what do we have on the board? We have an inductor and a capacitor?
You have a bunch of diodes and we have a little chip. That's an LED driver
If the rest of the components weren't to give away
That right there is it says l DB output
Pretty sure we saw something almost exactly like this a week or two ago on another
Mail bag, so I'm not gonna go too deep into these things
5 pieces 10 watt LED drivers 850 to 900 milliamp power supply for 9 watt 10 watt LEDs elect lamp bulb
I bought it from
electronic - firms and I
Paid door 84 the five of them at an auction
But electronic doctor firms, it doesn't sell it anymore
so I had to go and take a
Search around and here's a random seller pan-pan and supermarket have dealt with them before and they have it there
but when we got here input voltage 9 to 24 volts waterproof not
Output 8 to 11 current 850 milliamps up to 900 it said in the listing
Yeah for 110 watt LED
3 in series and 3 in parallel, which is how they are laid out on those little Cubs
and the last thing for today LED quantity 20 development board quantity 5, ah
That sounds like fun if I don't cut through them
Nothing else in there
Well packaged
Bubbles upon bubbles and in anti-static bags
Ok, so we do have 5 things here
And they're probably all the same it is a relay module
So we have a 5 volt DC coil on it
You have three screws over here, which are labeled with Chinese characters. Ah
But they are also labeled with a pictorial over here. So
normally closed
Contact common contact and normally open contact normal being the de-energized estate. So with as it sits right now
These two pins are connected if you energize the relay coil these two here
The switch flips over and these 2 will be connected
nice
but the reason for the module is that you can
Connect. Well, the coil of this is going to draw way more current than an Arduino pin or any microcontroller pin and can provide so
there is a we transistor in here which sits in between so that input
Will go to the base of the transistor or the gate of the MOSFET
and
these resistors will bias it properly that diode will be
across the coil of the
relay
Backwards in parallel to it but backwards so that basically when it
Gets power normally through its in the normal clarity. Nothing happens when the really drops out
So the transistor shuts off that really drops out
the
Magnetic field in that coil of the relay is going to collapse and while that's happening. It's going to induce a current
backwards through the circuit so that
reverse biased diode is going to clamp that voltage down to it's
it's forward voltage was gonna be about 0.6 volts unless it's a Schottky and
That will protect the rest of the circuit from a massive voltage spike. Nice. And then we've got two LEDs here. I assume
One is power and one is energized
and VCC and ground in
five pieces one channel DC 5 volt really switch module 4 Arduino Raspberry Pi thick arm AVR are
your shop - are sold it to me for
Well, he's selling five of these now for six dollars and 32 cents Canadian. I paid five eleven
He's not listing any other currencies, so you'll have to do the translation for yourself
Not much to see down here that hasn't already been said 5 volts one channel relay interface board
Standard interface directly connects to microcontrollers. Ah, the red LED is
for power on and the green LED is for
indicator for really the switch
so there and I was a little bit hasty in
Tossing out that packaging because he's buried in
The bubble wrap I found this when I was cleaning up before
This little order they call them piranhas style LEDs. I think they are
Looks like but 20 of them. Hmm
If I remember correctly these things were stupidly bright, okay, I got the power supply set for 5 volts and current limiting
at about 20 milliamps
so it looks like
soom doing this
So it looks like these two pins are common and these two pins are common. So
Guess if that's oh there we go. Oh, well, that is a very bright red
LED
Weight to balance it off here
There's the color a nice bright red, so these are those subtle piranhas are super flux
Also from our your shop - r is for pinning red piranha. Fuck's the wide angle bright LEDs
They're not selling them in 20 packs anymore
but here's their price for a thousand so their price for Tanner for a hundred would be
470 price for 10 would be 47 cents, so
Yeah, not too bad. I paid a dollar 38 for the 20 that I got
And these things are LED crystal-clear 5 milliliter. I thought the ones that I got were 3 no regardless
Anyway a 2 point 2 volts
622 625 nanometers is the way waiting for the light 30 degree view angle
And we're over here. Yeah
so
It doesn't matter if there's three or five millimeter
there's still two - two point two volts like most red LEDs these days and the different colors have a different forward voltage is
Just all totally common and normal for LEDs
Alright here. Is everything from this mailbag?
as
Usual a very wide range of stuff just because I can to order kind of randomly
So how long do these things take to get here?
The crimpers took 21 days because they shipped from canadian warehouse belong to one of these Chinese companies
That's interesting
Instead find it interesting these LED drivers took six weeks to get here the solder and the enameled wire
Took two months eight weeks
These touch sensors took nine weeks to get here
And these led these prana LEDs. Well, maybe that's why they called piranhas get off
the pronto LEDs and the
Relays took 4 and 1/2 months to get here
speed winner
slowpoke of the month
So as I think I mentioned off the top this is my 50th mailbag and
I wouldn't keep doing these things if it wasn't for the encouragement from you guys. Thank you so much and
as usual and extra special thanks to the
To the people over on patreon for kicking a buck or so into the tip jar every month helps me not go broke doing this
I'm having fun doing it. So I'm gonna keep on doing these so about every second week throughout the year
Maybe some extras on long weekends and stuff. I
have a playlist of all my
Mail bags if you go to my main page or if you just stick around to the end of the video
You know in minute or so. There'll be a link to the playlist of all my mail bags
the other thing
overrun reddit I've got
I've got a subreddit that I'll link down in the description of
Mailbag videos in general not just mine, but any of the channels that I watch that do mail bags
I've got them all well as many as I can anyway linked from there
Now if any of you guys do mail bag videos on your own channels, feel free to drop a link in there on reddit
Take some load off me and even if you know of other mailbag videos, they don't have to be electronics
Absolutely, drop them in there the more the merrier, right? There's not a lot of followers right now, but
You never know any little bit of publicity helps, right?
Thanks for watching. I'll talk to you later
