Convert Any 3D Printer To LASER Engraver - Duration: 5:16.
What is up guys, In this tutorial I am gonna show you how to conver any 3d printer
into a powerful 2.5 w laser engraver capable of cutting wood and engraving into almost every material.
So, We are gonna start this project by firstly choosing the right laser module for our needs.
Starting with 500mw laser you will be only able to engrave some shapes into wood, plastic or leather
and you can get that one really cheap for 35 €.
Furthermore, With higher power output lasers you are able to engrave deeper, quicker and also cut some plywood
and that is the reason why I chose a 2.5W laser which is just strong enough to cut 4mm plywood with multiple passes.
And when handling with laser dont forget to put on some safety glasses.
SO, I firtsly detach a fan and extruder and remove the main holder,
so I can drill 2 holes for the screws that are gonna secure a laser to the printer.
All the links of the lasers will be in the description below.
Secondly, we are gonna need 12v to 5v voltage regulator which is necesarray to control the power output of the laser.
3d printer fan port provides 12v at full power but Laser ttl modul only accepts a voltage up to 5v
so that is why we need a voltage step down regulator.
So, after soldering that together, I connect laserd diode, fan, ttl port
and main power input to the smal motherboard that you receive with the laser.
For the main power source I am gonna use this regulated dc power supply
but you can use any 12V power adaptor capable of providin at least 2 amps.
Now lets secure the laser to the main holder with 2 screws.
For best performance I would suggest you also drill some addtional holes for the airflow
but I didn't feel almost any heat generated by the laser so I guess that is not that important.
After that, I connect a 5v regulator to the 12v fan port which is gonna send the command how strong the laser should be during engraving process.
Last thing is to connect the motherboard with the main 12v power input and that it.
Now we can start calibrating the laser by firstly finding the right focus point.
Autohome all axes and try to turn on the fan somewhere from 1-255.
As you can see the laser is turned off at 0 and outputing the maximum power at 255.
Now I would suggest you place a piece of paper on the bed and reduce the power to a minimum
minimum so we can better see if our point is in focus or not.
You can simply adjust that with a small knob on the laser itself.
After you manage to do that, lets hop to the computer and download the needed software for engraving.
Firstly, download an inkscape software and two plugins for laser engraving.
Again, I will put all those links in the description box below.
After installing the inkscape, extract both plugins and copy the content to the written location.
Now, simply open the inkscape and firstly define the workspace of your printer.
After that import your favorite logo and vectorise it by clicking trace bitmat command.
Also, dont forget to resize the image to the final dimensions and place it in the left bottom corner.
So now, the first plugin we are gonna use is the one that are going to fully engrave the whole image on our material.
Choose the right output folder and Set the speed around 1000 and click apply.
The g-code will be generated in the txt file so open it and replace txt ending with .gcode and that is it.
As you can see that method is pretty slow but it can engrave some really nice logos
and also greyscale images but I will cover that up in the next video.
So the second methond is almost the same, you need to set the right engraving speed
and how many passes you want which is very practical if you want to cut some plywood.
I managed to cut balsa wood with only few passes but that is not the most amaizing part.
2.5 w laser is also capable of cutting some 4mm plywood but it takes a bit more time
and much more passes but all in all it is very practical equipment for all tech and diy enthusiasts.
And yea if you are into electronics you would also be able to create your own circuits and many other things
If you have any questions about the build, I would love to answer them and help you with problems that occored during the build process.
Thank you again for watching, lots of cool projects and tutorials are comming up so,
hit that subscribe button and I will see you next week, peace.

5 Must Read Books For STRANGER THINGS Fans with GirlReading | #BookBreak - Duration: 5:44.
Hi guys! I'm Kate from the YouTube channel GirlReading and I've spent the
past year pining for season 2 of Stranger Things to start. Whether or not
you've watched the show you're probably at least somewhat familiar with Stranger
Things but if not, very simply put, it is a Netflix original series that premiered
in 2016 and it is set in a small town in America
and basically follows the disappearance of a young boy and the strange
circumstances in which his mother, the chief of police and his misfit group of
friends have to face in order to get him back. There are secrets and superpowers
and murder alongside family, friendship, love and humor and it is basically a
total emotional rollercoaster. So, if you're like me desperately waiting for the next
series to start or you're watching this having already watched it and you're not
entirely sure what to do with yourself anymore, today I thought I would share
with you some bookish recommendations that hopefully may help to fill that
Stranger Things hole in your heart at least until you inevitably decide to
binge watch it from season 1 all over again. I have a somewhat eclectic mix of
books to recommend today: from young adults to adult to graphic novels but
each recommendation I do have is based off one or more specific element of
Stranger Things so hopefully I'll have something in here that contains an
aspect of the show that you especially love. My first recommendation is based
on the Upside Down, alternate reality aspect of Stranger Things and that is
Dark Matter by Blake Crouch. This follows Jason Desson who is a father, a husband
and a scientist as his world is turned completely upside down as one night,
after a night out Jason is followed home and knocked unconscious. When he is woken
up by a masked stranger, he finds himself in his life, but a life that has
completely changed. He is now a celebrated genius instead of a teacher,
his wife is not his wife and his son was never born. We follow Jason as he tries
to untangle the mess he's found himself in whilst also tried to work out which
of these words is real and trying to get back to the world he once knew.
Dark Matter plays with the idea of an alternate reality in a way that will
totally mess with your mind and make you question and think about everything your
life is and everything it could have been and all the what-ifs of life. It's
basically perfect if you were looking for a more scientific, realistic
explanation of the possibility of alternate universes and the Upside Down.
My next recommendation is one that I genuinely, the entire time I was reading it,
couldn't stop thinking about how perfect it would be for fans of
Stranger Things and that is The Call by Peadar O'Guilin: this is a young adult novel
set in an island that has been cut off from the rest of the world and is
basically a place where at any moment children and teenagers are at risk of
being Called and disappearing into a horrific other world in which they have
to spend the entire day fighting for their lives against the Sidhe who are
essentially these kind of evil fairies and this basically follows a group of
teens at a boarding school where they have been trained to fight to survive in
this ruthless other world, despite the fact that the majority of the people
that do end up being Called are either murdered whilst there or they've returned
extremely injured or mutilated in a multitude of ways. This is bizarre and
creepy and gruesome and surprisingly disturbing for a young adult book and
honestly if this and the show hadn't have been released around the same time,
I would have thought one had inspired the other and that's not because they're
exactly the same but they both do have very similar elements to them. If you
enjoyed the show I'm certain you will love this and if you enjoyed this I'm
also certain that you will really enjoy the show. If the 80s setting and group of
badass kids fighting monsters is what sucked you into Stranger Things then i
110 percent recommend Paper Girls which is a graphic novel, following four 12 year
old paper girls on the morning after Halloween in 1988 when they essentially
encounter an alien invasion. There's time-travel, vanishing
townspeople, spacecrafts, these giant flying dinosaur bird kind of things. The
art style and colors in this are absolutely gorgeous. You're basically
dropped right into the action from the first page. It's incredibly fast paced
plus it is the start of an ongoing series so although you will probably get
through this quite quickly, there are currently three volumes out with more to
come. For those of you looking to read something with magic and elements
similar to Eleven's powers, I have Gilded Cage by Vic James. This is a YA novel
set in a modern-day Britain in which the magic users control everything; from
wealth to power to politics and the people. If you are not one of the magical
elite, the ultimate one-percenters, then you owe them ten years of your service.
If you do those years when you are old, you'll never get through them but if you
do them when you are young, you'll never get over them. This follows two families
that have absolutely nothing in common except that they each have three
children but after one family enters the service of the other, their destinies
begin to entwine. This is another one that is the start of a series so
you'll definitely be able to get your alternate-reality, special power Stranger
Things fix from it for quite a while. For my last Stranger Things inspired
book recommendation, I couldn't not mention IT by Stephen King. It follows a
gang of kids investigating a horrifying force terrorizing their town. It is set
in the 80s. It is dark, it is twisted (even more so than Stranger Things) and I'm
going to be honest, I have not watched nor have I read IT by Stephen King because I
have enough trouble sleeping as it is. I have seen and heard it being compared to
Stranger Things so many times even I can't deny the similarities between the
two stories plus the new movie adaptation has just been released, giving
you even more opportunities to get your Stranger Things fix. So those are the
books that I would most definitely recommend to any Stranger Things fan
looking to fill that Stranger Things void and I really hope that I have
mentioned something that has intrigued you. If so, I would absolutely love to
know which ones. If you happen to have any Stranger Things-inspired
recommendations yourself whether that be graphic novels or books or TV shows or
movies or anything please leave them in the comments because I would very much
appreciate them and I'm sure somebody else would too. Lastly, I wanted to say
thank you so much to Book Break for having me and I hope you're all having
the most wonderful day! Bye :)

Draw My Life | CosmoProf Scholarship | Fall 2017 - Duration: 2:43.
Hi there my name is Catherine and right now my life is pretty exciting because
I've decided to change my career and pursue my passion of becoming a
hairstylist I'm so eager to begin classes at the Aveda Institute in
Houston this November but enrolling was just the first step
down my life-changing journey in 2012 I graduated magna cum laude from the
University of Houston with a bachelor's degree in history and I quickly dove
into a career as a retail manager and even use my degree to become a teacher
but it wasn't until I began working at a craft store Paper Source that I realized
how much I needed creative balance in my work life I've always been an artistic
person from hand embroidering to paper crafting and even enrolling in
continuing education art classes but my favorite has always been expressing
myself through hair makeup and clothes to be able to wear my art and what I
define as beauty through styling my hair and makeup is what gives me the most
confidence and self-assurance there are so many tools you can use to express
your definition of beauty it's my goal to learn these tools at the Aveda
Institute and share with others how to express their definitions of beauty
using me as their creative hair medium by doing this I hope to change the lives
of others by inspiring them to show their confidences through hair because
feeling beautiful inside and out is a life-changing thing after I realized I
was going to make my passion happen I sat down with my loving family and
boyfriend and asked what do you guys think of me going to cosmetology school
to become a hair stylist everyone immediately jumped at the idea saying
it was the perfect fit my boyfriend even joked that I already follow so many hair
stylists on Instagram anyway we then hashed out a plan to make my career
change reality but the only what if was financial aid I already have a college
degree and returning to school for more education after the expenses of
adulthood are already piling up is a really big commitment financially and
let's face it cosmetology school is expensive the scholarship would change
my life by easing the burden of the cost of cosmetology school for someone who has
already invested in post-secondary education not only would it
cover the missing portion of my tuition not covered by student loans but it
would also help my long-term goal of becoming a color correction specialist
and educator it would allow me to save for continuing education classes after I
graduate I'm so excited to begin this career changing journey and start doing
what I've always loved but changing careers isn't always easy
the CosmoProf Scholarship would be the missing puzzle piece to all of my worries

Extreme Adjectives and Idioms to describe fear | Halloween Special English Vocabulary Lesson - Duration: 8:13.
Welcome back to Love English Halloween Special! So, are you ready for some
scary adjectives and some spooky idioms? Shall we? Let's go!
So, who's your friend he looks a
bit scary? This is my husband, Mr. bones I'm lady bones. You don't look like
you've been feeding him. Yes we like to keep on a strict diet or bat and
spiders! So, everybody welcome to our Halloween lesson. So we're going to look
at some scary adjectives for you. So the first one of these is to be scared, which
is a very very common adjective to be scared. You can also say to be afraid.
Same meaning to be scared or to be afraid.OF! And we are afraid of something. So now I'm
afraid of Leila! I think she looks quite scary! I think I look lovely. So in this case
scary is an irregular Ed- ing adjective because normally with Ed and ING
adjectives the thing that we is making us feel the emotion has ing on the end
like for example: I'm bored because the class is boring but in this case it I'm
scared because Leila is scary! NOT scaring! okay yes not scaring!
Exactly, yeah. but we also have some extreme adjectives for you because
scared and afraid they're quite common they're a bit 'meh' What do you think of
those Mr Bones? Meh! so we've got two more extreme adjectives... to be terrified
when something is terrifying or to be petrified when something is petrifying
but remember with extreme adjectives you don't use VERY but you can use
absolutely terrifying, completely, totally but NOT VERY! Yes,
Now as well as adjectives we of
course have lots of idiomatic expressions in English to describe being
scared or feeling scared! That's right!
So, the first one is to be scared out of your pants! ah!
literally in this case meaning you're jumping out of your underwear!
They're still on! it's fine! So, to be scared out of your pants means you jump out of your underwear!
You are so terrified. Hopefully that's never happened to you and I don't really want
to see you see it happen to anyone! So the next one, now when you're very
very scared it can happen that you lose control of
some of your normal bodily functions. That's a very teacher way to explain it! Like going to the
toilet. So we have a lot of expressions in English and American English which
are all about being so scared that you lose control... Now...
this can be called to crap yourself, to crap in to go to the toilet. it's SLANG!
It's important to point out that it's the number two not the number one, yes.
or we can say a brown trouser moment, yeah, not very nice is it? No it's not, that's right!
I hope you've never had a brown trouser moment? I really haven't! I'm happy to say. The worst way to say
this is to say to 'shit' yourself. But you are not going to say that, you're not.
Crap yourself is much better. it's fine. Okay so that's a bit of a vulgar
expression for you. Now as well as saying to scare someone you could say that you
gave them fright! Boo!!! So to give someone a fright is to scare them!
So the next one we have is to jump out of your skin to jump actually out of
your skin you're so afraid now this is an idiom so it doesn't make any sense if
we actually try to look at it and understand it literally it is an idiom
so to jump out of your skin be enough to just be very very afraid and you can't
actually jump out of your skin that's right just trying to express when
someone is terrified that they do you actually jump there start and actually
if somebody gives you a fright like Lena was explaining before you can say that
you made me jump you make me jump yeah that's true have
you made me jump
really okay now this is a nice spooky idiot
we often say when we feel that something is strange you feel uncomfortable you're
a little bit scared maybe but someone's just water
oh now if you don't know what a grave is is the place where you are very then you
have a gravestone those viewing rights if you feel that someone's walk do you
lie in there like that yeah looking that lovely you will so to have someone walk
over your grave feels like summer my grave
yeah it's that feeling of something so that's why if you hit with those stories
where they all the fields are some awards across my grave
so this one is very similar this is where again we feel feels good or people
to sleep we feel freaked out to us I mean right I know yes which means we
feel scared and we can say oh I've just I've just seen something strange in the
room I feel freaked out or I can say sent shivers whichever sensor shiver
down my spine this is your spine the back yesterday to send shivers down your
spine boom quick okay the last one and actually a very common one describing
the sensations and the physical response that we often have to hear you know when
your skin goes all speckly sometimes when you're cold but also when you're
just scared we call them goosebumps referring of
course to the murder yeah it does get up yeah so to have
goosebumps is when your skin is all kind of Moon Kingdom and this is scary as he
is just skinny and bony so to get goosebumps to feel who
supports to express your fear okay everybody that was our Halloween special
and we hope that you feel afraid and you're in the mood for her rude scary
things now that was also our one-year
anniversary probably less

How your muscular system works - Emma Bryce - Duration: 4:45.
Each time you take a step,
200 muscles work in unison to lift your foot,
propel it forward,
and set it down.
It's just one of the many thousands of tasks performed by the muscular system.
This network of over 650 muscles covers the body
and is the reason we can blink,
smile,
run,
jump,
and stand upright.
It's even responsible for the heart's dependable thump.
First, what exactly is the muscular system?
It's made up of three main muscle types:
skeletal muscle, which attaches via tendons to our bones,
cardiac muscle, which is only found in the heart,
and smooth muscle, which lines the blood vessels and certain organs,
like the intestine and uterus.
All three types are made up of muscle cells,
also known as fibers, bundled tightly together.
These bundles receive signals from the nervous system
that contract the fibers, which in turn generates force and motion.
This produces almost all the movements we make.
Some of the only parts of the body
whose motions aren't governed by the muscular system
are sperm cells,
the hair-like cilia in our airways,
and certain white blood cells.
Muscle contraction can be split into three main types.
The first two, shortening muscle fibers and lengthening them,
generate opposing forces.
So the biceps will shorten while the triceps will lengthen or relax,
pulling up the arm and making it bend at the elbow.
This allows us to, say, pick up a book,
or if the muscle relationship is reversed, put it down.
This complementary partnership exists throughout the muscular system.
The third type of contraction creates a stabilizing force.
In these cases, the muscle fibers don't change in length,
but instead keep the muscles rigid.
This allows us to grip a mug of coffee or lean against a wall.
It also maintains our posture by holding us upright.
Skeletal muscles form the bulk of the muscular system,
make up about 30-40% of the body's weight,
and generate most of its motion.
Some muscles are familiar to us, like the pectorals and the biceps,
Others may be less so, like the buccinator,
a muscle that attaches your cheek to your teeth,
or the body's tiniest skeletal muscle,
a one-millimeter-long tissue fragment called the stapedius
that's nestled deep inside the ear.
Wherever they occur, skeletal muscles are connected to the somatic nervous system,
which gives us almost complete control over their movements.
This muscle group also contains two types of muscle fibers
to refine our motions even further, slow-twitch and fast-twitch.
Fast-twitch fibers react instantly when triggered
but quickly use up their energy and tire out.
Slow-twitch fibers, on the other hand, are endurance cells.
They react and use energy slowly so they can work for longer periods.
A sprinter will accumulate more fast-twitch muscles in her legs
through continuous practice,
enabling her to quickly, if briefly, pick up the pace,
whereas back muscles contain more slow-twitch muscles
to maintain your posture all day.
Unlike the skeletal muscles, the body's cardiac and smooth muscles
are managed by the autonomic nervous system
beyond our direct control.
That makes your heart thump roughly 3 billion times
over the course of your life,
which supplies the body with blood and oxygen.
Autonomic control also contracts and relaxes smooth muscle
in a rhythmic cycle.
That pumps blood through the smooth internal walls of blood vessels,
enables the intestine to constrict and push food through the digestive system,
and allows the uterus to contract when a person is giving birth.
As muscles work, they also use energy and produce an important byproduct, heat.
In fact, muscle provides about 85% of your warmth,
which the heart and blood vessels then spread evenly across the body
via the blood.
Without that, we couldn't maintain the temperature necessary
for our survival.
The muscular system may be largely invisible to us,
but it leaves its mark on almost everything we do,
whether it's the blink of an eye or a race to the finish line.
