Hey guys!
It's time for another crack at the annual Maker Secret Santa
We've been challenged to make a unique gift for
less than 80$ for one of the other youtubers in this event
Last year we made the nuclear maker phone and gave one to each maker, they were a bit buggy though...
Hi James! I'm calling you on the hack phone!
Hello?
The channels are: Kids Invent Stuff
James Bruton of xrobots.co.uk
The one and only Colin Furze
This Old Tony
Sam from LOOK MUM NO COMPUTER, who gave us the awesome Furbtrio last year
My good friend Allen Pan of Sufficiently Advanced
And finally, the ecstatic is Stephanie
This year we're making something for Kids Invent Stuff, so we're going to try and
make them their own metal sign just like our awesome Hacksmith logo we have on the wall
Let's get started
It's gonna be tricky to keep it under eighty dollars...
I've got the laser set up to cut out the steel pieces, all I need to do is press start
Let's do that
All right while the paint's drying we actually just got a special package in the mail
I think it's our secret Santa gift
The real question is: Will we be able to tell who's it from based on what it is?
It's a lot of padding
Fills the box
Suspicious...
More suspicious...
I'm really not sure what this is
The packaging kind of makes me nervous
I gotta say I'm impressed with the packaging on this
This looks freaking cool
Wow
Happy Christmas Hacksmith
It's got a screen on it too!
It's a robot head, I think it must be from James Bruton
The superhero alert system from James Bruton to the Hacksmith
Set up info: Place orange light on top and connect the xt60 connectors
Batteries not included, use a 12 amp volt 5 amp power supply or a 3s lipo battery to power it
Okay we might have to go grab the battery
Wow!
Okay I'm gonna go grab a power supply I'll be right back
Good thing we have a whole box
All right let's go try it out
All right we got the power supply, now we just have to plug it in
All right, okay so explanation
What he's done here is he's got an NVidia Jetson in there and a little webcam and
basically it's actually using image recognition using AI to determine if the superhero is nearby
So apparently he's trained it to have four different categories
He's trained it with a hundred images of my face because I guess I'm a superhero
30 images of Captain America's shield
30 images of Thor's hammer
And 50 images of random people with short hair and no beards
and if you fall into that category you're not a superhero apparently
I guess Chris Evans would have something to say about that
Anyway let's see what happens
Yep it recognizes me as the Hacksmith, that's pretty cool!
Check it out, Captain America's shield
What about a different Captain America shield? Yep
How about Thor's hammer?
Recognizes all three at once!
This is actually a really cool bit of engineering and utilizing neural networks-
Is it even using neural networks?
I don't know, I'm not a software guy but this is pretty awesome
Owen why don't you stay in front of it see if it recognizes you
Not Hacksmith!
Yeah 93%
What if the real Hacksmith's here?
There we go
Well I guess we're not upgrading our security system to facial recognition anytime soon
All right the painting's done and this sign is looking awesome which means
all we have to do is the final assembly
Got some vhp tape, got some tools, power supply, screwdriver and the LEDs so let's get started
So to connect the two led strips together we're actually just going
to connect the communication wire which is the green one right here
We're going to use this nice little quick connect thing
Connect the red wires together
All right the LEDs are plugged in and working
Let me show you how they work because these are actually RGB addressable LEDs which means
a little controller that we added means we can actually add tons of cool animations
So the software is really cool you can do a lot with
it as you can see there are tons of options here
You can actually program in which strip is which
So the inner strip is actually LEDs 0 through 22 on the rgb LEDs
And then the second strip is the LEDs from 22 to 43
So we actually have the outer LEDs doing a mirror effect
Right now the effect is actually going up to the
top and stopping and then starting again but we can actually take that off as well
And then that kind of changes how the effect works, now it's just going in a full circle
So really cool software, super easy to use and it's open source which is awesome
If you guys were paying attention we're actually missing the center of the D
and the center of the E
So what we're going to do is glue this down from the back side and then
we can glue the missing E and D center pieces to the plastic
All right so unfortunately we used our entire budget making a sign which means I had to make
this box out of pieces of old boxes that we got in the mail so hopefully it arrives okay
Time to mail it off!
All right let's hope they like it
But the real question is: Did we stay within budget?
Let's see well we used about 16$ worth of steel
3$ worth of nitrogen gas for the laser
10$ of LEDs
A 15$ LED controller
5$ of acrylic
A 10$ power supply
10$ worth of paint and we managed to save some money by using old cardboard for the packaging
That comes to a grand total of 69$
(Not including labor)
Oh wait that didn't include the shipping fee of 278$... Crap
Well that's what we get for doing this last minute anyway
I hope you enjoyed this video maybe learned a thing or two about making awesome LED signs
and of course don't forget to check out all the other awesome makers involved in the Secret Santa
We've put links in the description below
Happy Holidays!
