welcome back we find ourselves in the middle of a month of mailbag Mondays
yay today the beer that I will be sampling
along with this is diesel fitter stout from Torque brewing in Winnipeg roasty
and malty and dark 65 ibu for those who are playing along at home very nice
indeed first there man is plastic sheet oh
goody wonder what kind of a plastic sheet it isn't
ah it's actually a module cool it is
specifically a d1 mini data logger shield real-time clock and micro SD so
there is the battery to power the real-time clock it's a CR 220 it says
which I don't think I have huh and on the back side is the data logger
function there is an SD card there is a crystal that is slightly mangled and
there is the brains of the operation hmm is that chip both the real-time clock
chip and the SDR is its separate functions the s130 7 I think that's a
real-time clock chip which means that I guess it's just handling the SD card
directly there's not much to an SD card reader Datalog shield for Wi-Fi d1 mini
RTC DS 1307 micro SD for do you know us not sure what us means in this case I
got it from DIY electronic I got it at auction for a dollar 31 which is about
99 American cents or something like that free shipping of course so it can save
data files on any fat16 fat32 formatted micro sd card and it hasn't RTC that you
can use and you're still in your code to timestamp your data cool so the
real-time clock you need SEL SDA and the micro SD card
you need caulk that you note and chip select okay that's pretty
straightforward and they're all it tells me what what pins they're on which is
really handy no I gotta do is wait for some D one minis to come in because they
used the last one that I have in stock on my Christmas lights off to a good
start so far what is next it's an original IC driver x two original as
opposed to a copy one if we go even though okay it's a bunch of teo of those
oh those aren't transistors those are four pin device okay and something else
in this other bag here in blue let's look at what these guys are first hmm
says d v 2 v 2 F and 1901 you know gues 19 owns a date code nothing on the back
at all and guess I'm going to have to go to the listing to figure out what these
guys are 20 pieces QX v 2 v 2 F or QX 55 2 or 5 2 5 2 F new and original IC
driver I originally got it from this dude planet - Earth's who has all kinds
of random weird stuff but they don't have them right now so I'm guessing it
was an auction I paid a dollar 12 for the 20 of them and I'll link you to this
search but here's a random seller that's selling them there's a whole bunch of
people there selling them and buy it now seems to you about buck 30 Canadian or
99 American so if you're interested but none of them said what the hell it
actually does so I hit the resort to go into the datasheet so the datasheet
tells me that it's the solar LED powering chip thing runs from just under
one wall to one and a half volts it can it can push up to this not push
it can supply up to 300 milliamps which is wild so basically you connect it like
this solar panel to the s bat pin the actual battery to the bat pin with an
inductor a couple of LEDs in parallel and it's got a MOSFET inside that
switches this on and off so it's yeah it's kind of a little boost converter
solar charger and and darkness sensor off the solar panel all in one little
package and twenty of them for basically a buck a couple of components so this is
what's at the core of your average dollar store solar light well those
could be fun to play with even if you don't use the solar you could probably
just use them off a off a double-a battery or something to power an LED for
quite some time anyway in this other package that I accidentally sliced off
we have some blue hmm looks like oh no it's tubing oh okay
this is uh this is heat shrink tubing that I think is sized for an 18 650 yeah
that's exactly what it is it's a heat shrink sleeve so you if you are messing
around and you happen to Nick or remove the heat shrink sleeping on your 18 650
just to re-insulate it you can put this over and shrink it down and let's just
actually see how shrinky it gets
well while that goes way down so that'll get down a nice and tight and make a
nice nice skin on your battery and it's fairly strong stuff to you actually okay
every candy have a just-in-case 18 650 lithium-ion battery heat shrink tube
wrap skin PVC shrinkable film tape sleep flap from that seam seller planet -
earth and they also don't have this in stock anymore which means I also
probably got this at an auction I paid 99 cents for it and apparently
you can get it in a multitude of colors fun next thing in we have controller it
says this one shipped from Malaysia and one of the other ones did as well and I
think one of these other ones as Estonia on it I'm trying to find other countries
other than China to buy this stuff from just for some variety is controller it
is a remote control and a thing okay it's even got a manual of sorts that's
good led me dream color controller aha well that pretty much gives it away
doesn't it so we have an infrared remote control it's got a little plastic thing
in here in the battery pre is it actually battery included no they
wouldn't include a battery would they you man yet
what's painting no they didn't cr2025 huh it's 2032 fitted in there how to try
it anyways we have different colors and modes there you have an infrared
receiver there you have a DC input there and three output pins for RGB which
means this thing talks to neopixel II strips
hmm DC 5 volts Tony war volts Mini 21 key IR remote controller for ws2812 B or
dubious 2811 LED strip lights I got mine from this dude packs abou me - zero I
got it for 2 dollars and 31 cents he's got some other ones right now but he
doesn't seem to have that one for sale right now so I will link to this search
here but here's the description from some random other seller not much that
we don't already know just the input DC voltage battery and yeah and I don't
know why it says common anode because that's not really how OWS LEDs worked
but anyway let's go play with it for a second shall we
even though this says it's a cr2025 a cr2032 seems to fit so jam that in there
and i've got a strip of neopixels AKA ws2812 just a meter long strip but that
should be good for now does it probably want this thing flipped
over so that the infrared window is actually facing here got them connected
up to 5 volts from my power supply so on and they are doing what you'd expect
neopixels to do okay so make sure it off I can turn it back on okay um Auto dis
whatever blue does that
the different colors all do their magic that's full white that's a meter so
let's see that's drawing one point almost 1.8 amps
Wow for a meter let's go to blue red that's just under an amp and it wears a
green I guess there's a green green huh there's green ok yeah so they're just
shy of an amp each ok and breaking this up
bring this down yeah that all works ok very cool so I see people and read it
all the time asking where can I get a simple controller for neopixels for
ws2812 there you go right there and it was cheap oh yeah we have next expansion
board module a small one a single transistor dough is 18 B 20 oh that's
not a transistor this is something kind of bizarre and cool
Dallas D is 18 B 2018 B 2009 t 2 thermometer temperature sensor I got
this thing from good module I got it at auction for 55 cents they're currently
selling one for dollar 59 I noticed when I was searching for this listing there's
others for auction right now for fairly cheap and multi packs and stuff like
that but what makes this an in such an interesting little temperature sensor it
uses a unique one-way or interface requiring only one pin for communication
which is fine I guess but you can actually use these there's a
couple molds you can use them you can give them power on ground and then
there's one bi-directional data pin which is sort of interesting
but the other mode you can give it just ground and the communication wire and it
will derive its power from the communication line so as long as you've
got a common ground in a system you can you can run a single wire from your
controller to this thing and the other thing you can put them on a bus on that
single wire you can put them on a bus and you can address each one by its by
its unique serial number so you can put a whole bunch of them scattered around
your environment I'm not sure how long the bus can be but you can put a whole
bunch of them out there and talk to them individual with just a single wire
running around the room or running around the place which is pretty damn
cool so there's only a couple of applications where that one way or
protocol gets used one of them is in those temperature sensors and the other
one is in these little button things these are a little data thing and they
get used for keys for identification that kind of stuff for a lot turning
on/off arm systems oh I didn't know that apples Meg safe thing uses with the one
where protocol as well okay so there's a third different way that that it gets
used but really it's not used all that often he says here that with with
special bridge drivers and stuff you can run them up to a hundred meters or up to
300 meters on twisted-pair Wow that's nuts
also interesting is that there is a library for it for Arduino which is the
real reason that I got it just to play with there's actually an application
that we use them at work there's one piece of equipment that uses them the
temperature sensor to monitor cabinet temperatures they've been a little bit
hard to get from that manufacturer so I figured if I could make this one work
and also if I could make up some kind of an Arduino box to just test them to make
sure that they're installed properly and working properly at work it might be
handy yeah here it's talking about that that parasitic power option
so that works up to 20 feet away from heart we know that's pretty slick I'll
have to play with that in the future in a few months somebody remind me in the
comments that I've forgotten to do this and I'll try and get around to it okay
and the last thing in we have light oh
wait did I order ooh a horribly crushed one that sucks
thank you post office you really hmm looks like it's not damaged anyways now
let me go find my adapter and oh check the listing home at it and then we'll
come back and see what that does led bedroom baby night like you us plug
Auto LED induction sensor control light I got it from perfect store one one one
they've got a bunch of the round ones like I got up for auction right now but
those auctions are gonna expire by the time you see this so I've just link to
one that they've got on buy it now which is a square one
currently they're Buy It Now price is about thirty-five Canadian I paid 93
cents at auction and most of their auctions are running writing around that
price right now anyway for the round ones and they also got square ones and
heart-shaped ones unfortunately I got the EU one which I wasn't really
intending to but whatever that may have been a shipping air that might have been
me not reading the listing properly it says it works all the way 410 to 250
volts so I should be able to just use an adapter I think colors they have various
colors whatever doesn't say much the light becomes dim in the room the wet
will auto open power-saving right so it's a light controlled night light this
is also my first opportunity to use my new power meter so there should be
exciting how many watts do you think this thing
do oh yeah the other thing I get to use the Deaf nap there how exciting
so what's going to happen when we plug this in nothing because mmm because it's
too bright in here Oh point one watts okay now if we cover the photocell
nothing continues to happen so we're selling a bit more opaque than my finger
no hmm there we go completely dark in it there you are still only drawing 0.1
watts yeah
nine milli amps and a power factor that it just can't read it solo okay hmm oh I
guess there's nothing for should I take this thing apart right now now I'll save
it for another video to take it apart but clearly it's not well yeah it's
drawing so little power it's sort of below the threshold of the meter even to
read it and there is the contents of today's mailbag monday quite the quite
the assortment as often happens so what transit times this nightlife guy
took one month to get here these LED driver bees yeah whoa voltage LED
drivers and the heat shrink took exactly one month as well this combination SD
shield and real time clock took three and a half weeks this
lighting controller over here and it's remote control took four weeks as well
and uh-huh the Delos semiconductor one warrior temperature sensor took three
weeks well that was fun
that's gonna be a fun teardown sometime in the future this thing's gonna be
interesting to play with once I get another d1 mini back in that'll be good
to play with this is always useful yeah fun fun fun all right well thank you for
watching those of you who had the patience to make it this far through the
video I always appreciate that uh thanks to my patreon supporters for helping me
fund this nonsense you guys are awesome and generous and just generally good
people really appreciate the help yeah thanks for watching the
continuation of the month mailbag Monday's will return in 7 days
