tonight's opening begins with juice of the Oats Oatmeal Stout from axis Brewing
Company in Winnipeg they describe it as having a creamy smooth body and an easy drinking dark air
with the aroma of coffee and chocolate all right here we go what does this say it says electrical
equipment and supplies probably the most accurate one of these that I've seen in a while also most
vague a bunch of dip ICS it says CD 4066 there which is also what it says on the chip so that's
very likely what it really is I just wish I could remember what those are and why I ordered them 10
pieces CD 4066be new and original icy inline dip 14 bi-directional analog something either
um I paid two dollars and nine cents Canadian for this with 19 cents shipping looks like I
bought them back in January and they're supposed to arrive any day now woohoo unfortunately I can't
find the original listing for these things so I'm guessing that the guy that I bought them
from no longer exists on eBay so the link down below will be to this search which should find
you what you're looking for and even cheaper than I paid for it so what this is is a quad
bilateral switch CMOS technology old school um it can switch analog signals for routing them
or turn them on and off and stuff like that basically uh a microcontroller controlled
switch or oh doesn't have to microcontroller but you know there is the pinote and whatnot
so it's just got a bi-directional signal through it so you can put signal in pin one and it comes
out pin two or in pin two and it comes out pin one and the control lines will turn on and off
those for instance an old school uh audio visual system that's completely analog you could switch
the audio through these and actually if they're high frequency enough probably analog video as
well if you want to control which input is going to your amplifier something like that well those
were interesting let's see what's next it says USB charging cable I hope it's not another one that
I've got a hundred of now they ordered a bunch of stuff before all those cables came in from a donor
USB a to USB C oh oh I remember what this one is now Julie and I had a few
months back showed a cable that had a little Vault and current meter in it
so I think that's what this is let me just connect it up here yeah it seems to have a
little watt meter on it that's pretty cool and if I can trust that it can run up to six amps
which seems silly for a USB cable but whatever oh uh I'll take their little eyes so let's just see
if it agrees with the for nursery USB tester so we've got 4.68 volts coming in through the cable
after the losses so there's exactly five volts well 4.99 going into it so we're losing about
0.3 volts through the cable we are drawing 4.1 watts to my load this thing is claiming
4.6 Watts okay that's close it's not perfect but it's not too bad for something smaller than your
little finger at least it gives you a rough idea of what's going on 2K type c to type c cable 100
watt PD fast charge charging USB C to USBC display cable that's not huh is that a no this is e to C
oh okay uh some of them are CDC okay I got the 66 watt 8C in Brown uh one meter cable
for four dollars and forty six cents and free shipping okay there's what it calls high speed
data transmission 480 megabits per second sure it says it's got this built-in e-marker chip which
helps to stabilize the current and voltage oh so it's not just monitoring
okay I wonder what this e-marker thing is uh thick tinned copper cores
well we saw that over that one meter we had about a third of a volt uh drop which is not ideal but
I guess it's better than a lot of the cheap cables that I've got around here I'm gonna have to uh
try this out I'm thinking that my application is just going to be day-to-day charging on my normal
phone so I can quickly glance and see how close to finish I'm I am charging well you know having to
go to all the trouble of waking the phone up and looking at the screen but it it seems like a cool
little toy anyways right next thing in doesn't say what it is it's not even pretending all right
pens Oh Long nib markers oh okay I've been seeing some of the maker YouTubers using these things
lately or probably the name brand version of them so I figured when I spotted them I'd uh grab a
cheap assortment pack so this pack has five markers or pens each one in a different color
um green and red blue and black and white I guess if you're writing on something black
that would be useful let me just grab the bag from the last thing and see what that looks like
yeah that's all right but the point of these things what makes them interesting is that
long nib and the reason that's interesting is if you're marking holes in something or marking
through a hole in something that's uh got a fairly deep hole in it like this thing is about six or
seven millimeters thick you can get right down into the hole and make a nice accurate marking
for your drilling or whatever other operation comes next in your making process those aren't
you know the most earth-shattering thing in the world but I think they're pretty cool and
they will have some applications in the workshop maybe not so much in the electronics Workshop but
in the overall Workshop piece is 20 millimeter long mouth marker pen long tip bathroom carpentry
ceramic tile woodworking deep hole decoration quick drying oil uh yeah the search term you'll
want is deep hole marker deep hole pen or long tip marker or long tip pin but I will link you
to this listing I got the color five colors mix for five dollars and 29 cents Canadian they look
like they're on sale right now but I don't know if they will still be when you see this anyway if
you search for some of those Search terms you should find them anyway don't know what more
to say about them really that we haven't already said about them anyway there's the dimensions sure
and yeah the tips of them are one millimeter wide most of them except for the white one which is 0.7
and they seem to make nice marker marks similar to the super the uh 0.7 millimeter Sharpie tip I
wouldn't expect them to be as high quality as a Sharpie marker but time will tell I guess we'll
find out right the third thing in it again doesn't say in English on there what it is
I wonder how Customs does their job when they can't read what the customs declaration is
oh it's a kit hey there's a lot going on in here we have a speaker we have some shrink
tube we have a 28 pin dip socket some standoffs a circuit board in the back and even instructions
so there is the schematic we've got looks like a bunch of LEDs there
um connected to this microcontroller a bunch of resistors with variable resistors there so
voltage dividers hmm same number of those as LEDs okay the speaker which connects to the
microcontroller as well we have a little power section and even more LEDs there
and then more LEDs there but they're labeled gg1 or GG or IG something that doesn't help me those
are GG one through seven okay 40 pin chip oh it's an STC 89c52 microcontroller okay I don't have
Google translate on this phone it's a much older phone but if you guys want to uh read it go ahead
I am probably going to find out what it is by reading the listing but let's take
a quick look at the circuit board and see if it says anything those weren't variable
resistors there light dependent resistors I I guess they are variable resistors then okay
and then this snap off board up here looks like what's holding LEDs so yeah there is
ldrs in there not seeing LEDs but oh these are those little laser diode modules this is uh what
is it a laser harp I think is what this thing was called it's a musical instrument that you
play by breaking the beam between the little laser diodes and the white dependent resistors oh that's
cool yeah laser harp kit 51 SCM electronic piano kit music harp DIY electronic production kit Parts
5.91 cents and a dollar 98 shipping this is a picture of a symbol down in the corner there
I think I may install the wiring a little bit more neat than that a harp without strings
bright red laser beams representing seven notes when we need to move the beam that is block the
laser with their fingers just like you're moving the string well that's cool you can also adjust
the pitch including bass mid-range and treble 21 different tones available oh that's Nifty
so how do we I guess these two buttons will adjust the sure it's a microcontroller so
you just do it in software why not so those will be the adjustments there's LEDs for a
wool medium and high so that will be I guess adjusting the pitch or something like that
and then sure there's the variable resistors the light dependent resistors getting a voltage
divider there there is the laser diodes up top and there is just regular LEDs
okay so as you're playing it I guess it lights up other LEDs sure there's little LEDs beside
the weight dependent resistors oh that should be a cool one to put together you see I'm restocking
on kits because I went through a bunch of my kits last December in my December of Kit builds so I'm
not sure whether I'll do this one during the year or whether I will save it for December because it
promises to be an interesting little kit and the last one in this one came to my PO box
which means one of y'all sent it to me and all it says on here is board so I wonder what it is
oh it's two little boards okay any sensor series got LEDs oh that is a reflective
uh sensor one of these infrared LED one of these is infrared photodiode and if an
object is close enough the photodiode will see the LED and turn on or off depending on
the distance it's not an analog device it's not like those um ultrasonic distance finders this
is just a go no-go but and you can adjust the sensitivity of it with that part there so I've
used a bunch of these around my model railroad for detecting the presence of trains I will put
a link up there to one of those Ancient Ancient videos like six plus years ago I think probably
um but these are a cool handy little device and the other one I think I recognize this guy
yeah that's kind of what I thought it was this is a breadboard power supply
basically you take this guy and you park it on the power reels of a standard breadboard
some fit better than others that fits pretty well you see here it has positive a minus
there and positive minus there um which line up with the red and not red power rails on here
and then up here you have a jumper you can either choose 3.3 or 5 volts and over here you
have another one you can choose 3.3 or 5 volts so you can have a different voltage on each side of
the power rails for different things going on so it can take a barrel Jack input as a power switch
there says right now between 7 and 12 volts it's a little protection diode to make sure that you
connect your Barrel Jack in the right direction they're supposed to be standard not always a
little smoothing capacitor led to tell you if it's powered on or not and a 5 volt output which is
kind of Handy you can also pick up 3.3 and 5 volts off these pins if you need to run them somewhere
off board here is where the magic happens these are lm117 voltage Regulators a linear
voltage Regulators one of them is a 3.3 volt one of them is 5 volts they can handle I think
up to about three quarters of an amp they're not the most powerful devices in the world but for
most breadboard projects they're adequate the only caveat with the lem117 is that if you do overload
the output if you happen to short the output or something like that and cause them to fail
a lot of the times more often than not they will fail in a short circuit from the inputs to the
output which means instead of getting 3.3 volts going to your project you will get the full 12
volts going to your project if you damage one of these so just be aware don't be plugging stuff in
and out with a with a powered on and double check what you're doing before you power it back on
and you should be fine one thing that I've done for other ones of this same module that I've had
for a while it's a different brand but it's pretty much the same thing I have instead of using that
jumper I've made up my own jumper and it's got a little NTC fuse on it an auto resettable fuse
so if I post stupid and draw too much current out of it then that will hopefully shut down
the circuit before I blow up the regulator and if you look carefully at this 5 volt regulator
here you will see the soldering is not Factory I have replaced that one and that is how I learned
the lesson about protecting these things but as long as you're careful with them and don't uh
I said don't hot plug stuff and double check your work these are an excellent addition to
anybody's shop that uses breadboards and there is the contents of today's meal big Monday haul
lots of fun stuff in here this laser harp kit should be fun to put the other one I
get around to doing it as I said I'm not sure if we're going to save this for December kit
extravagance again if we're going to do it when I'm bored during the summer or maybe on a rainy
day or something I'm not sure um these what are they uh quad bi-directional switches should be
interesting for an audio switching project he said I'm gonna have to go back and look at my
notes but I think I remember the wanting to use these just for for messing with analog audio this
charging cable with the little watt meter in it is kind of an interesting and silly thing
I probably going to use it for a while on my uh on my phone by my nightstand just to uh is to see
how well it works for a while and yeah maybe some other applications will turn up and he's deep deep
hole Long Reach markers should be a handy thing to have uh out in my garage or my workshop just
for doing various projects just as a consumable you never know when you're going to need things
like that and then thanks to whoever sent these two modules in I've used both of them in the past
they are very useful modules and I'm sure it will get use out of them in the future again
uh well in addition to all that I want to thank my patreon supporters and my YouTube channel members
for helping me buy all this stuff and keeping the beer fridge full um thanks to everybody who keeps
watching this stuff questions and comments down below as always I'll talk to you later
