Hey guys, I'm the Hacksmith and this is make it real we've actually done quite a few Overwatch projects over the years.
But on this episode of Make it Real we're making everyone's favorite Overwatch character Mei!
As I was saying. Everyone's favorite character?
Several months ago. We hired a co-op student within the University of Waterloo to help design and build some projects here.
Her name's Elena and she fit right in with team here at Hackmith Industries.
This this is freaking awesome.
Ah man, i'm never going to get this done!
Elena's gonna try it now.
No, you're done
You're done
Anyway, she knows mains exothermic ice blaster on a project list and asked if she can make it. We said why not?
Hope you guys enjoy the video.
Okay, so how are we gonna do this in the game her weapon literally freezes bad guys.
So we're gonna use co2 which is also known as dry ice.
For convenience, we can use a fire extinguisher tank.
To control the flow we'll be using a linear actuator to pull the fire extinguisher lever.
To make it shoot more like a gun in the game.
We'll upgrade the nozzle. We can control this all with the wire and then make it look pretty. Piece of cake.
This episode will be amazing. I can't wait to get started
We should compare notes sometime
Wow
We actually have a more detailed
Electronics diagram which you can check out using the link in the description below to visit our project on maker dot IO
Watch this, is it getting cold in here?
You should have gone for the head.
This is awesome
Go into commercials. We'll be back after the intermission
This video has been sponsored by Simply Safe. An easy to use customizable home security system.
Which is great because Ian lives on the wrong side of the tracks
Side of the tracks.
I Lived here for two years. And in that time I've had three break-ins.
This is my back door that was kicked in. I've also had to board up the windows in my shed. I'm sick of it. I don't want another one.
Which is why we're so happy to get a Simply Safe sponsorship.
It's an incredibly effective and reliable home security system that's super easy and intuitive to install.
The sensors are tiny. You won't even notice it's there and since everything is wireless
Anyone can install themselves without any to be an electrician, but don't take my word for it
Let's hear about some of the features for Ian.
This is a freeze sensor, so your pipes don't burst.
This is my sump pump. So I'm gonna put the water sensor here.
I've got a security camera, but let's be honest. I'm gonna use it to watch my cats.
Just plug in the micro USB it's got a panic button
Plus it's super affordable with honest prices and no contracts or hidden fees. And if the power or Wi-Fi goes out it still works.
Monitored by professionals 24/7 you can sleep easy at night knowing that in case of an emergency
The monitoring center will notify the police and get you help
Check out SimplySafe.com/Hacksmith to learn more and get your own security system.
How it's going great.
Until the end.
Every connection causes a flow restriction.
Try number 343.
Thumbs up to that.
I'm going in
I'm just trying to do the best I can.
Amazing!
Loud noises!
The nothing serious
Don't worry about it!
Way to go
I've come to appreciate zip-ties.
Ta-da. Zip ties.
Did someone say overkill?
These zip-ties are only 50 cents each.
We are almost there.
Okay ready.
That's an empty tank, isn't it?
There was a hosepipe on their.
Was that a success?
Half way. That could have gone better.
Did I scare you?
Oh Yeah!
So what happened was the hose came off of the gun and it ripped off the wires connecting to the trigger
So the linear actuator stayed in position and it kept shooting dry ice around and scaring people off.
So this time I added a couple of relays so that if that happens again
Then the linear actuator goes back to its position and it stopped shooting ice.
I'm never ready Well, there's not a lot of gas left. So we'll see.
I'm getting good at this.
Wow, that's nice.
I'm ready to start a blizzard.
Oh my god it's so cold.
Nice.
What does it do?
Loud noises.
Again
Ohh nice hair.
Time to see if we could free some water.
It's empty.
What?
Disappointed!
Let's see if we can freeze this water.
All right, i'm going to blast it.
See that?
It's curling right off the edge.
Alright, let's see what's better. A Not a Flamethrower from Boring Company form Mei's Ice gun.
Scared?
Haha.
I Guess this really is not a flamethrower
So, hang on why is it so hard to make stuff freeze even though it looks effortless in the game?
Well changing the temperature of water actually takes an insane amount of energy. To cause an effective heat transfer.
As you guys know Colin Furze actually made a liquid nitrogen freeze gun a while back and even shooting liquid nitrogen at water.
Well, it took a very long time to freeze.
I know Let's try freezing like a cup of water. That is a true test.
How cool does that look? It's completely frozen.
Since dry ice isn't even as cold as liquid nitrogen
The best we're gonna do is make things a little frosty.
For example to freeze an entire liter of water
We need about 770 grams of dry ice. Assuming perfect heat transfer.
Which we don't have when we're shooting it violently from a ice gun.
Most of its being absorbed by the surroundings but it is still an awesome looking cosplay prop.
All right, so it's not actually that good at freezing things but it does work as a pretty good fire extinguisher.
Which is quite handy considering
I'm on fire.
Mei. Mei. Mei!
All Right, that was pretty awesome. Elena did a fantastic job on one of her first make it real projects
Don't forget to check out her other project that she made Pandora's box
Unfortunately, she's back at school now to finish her engineering degree.
But we've hired a new co-op student to replace her Charles. Charles get over here
Charles! If you guys are interested in working for Hackmith Industries
We do actually take on co-op students from local high schools and universities and colleges.
Unfortunately at this time we can't accommodate international students
But maybe someday in the future when we have a larger facility and our business is bigger. We'll be able too.
Well I hope you guys enjoy the video. It smells really bad
Which is pretty handy considering
You're not flammable.
