- Hello, and welcome to another "Guest Conductor" video, here on the Coding Train. Well, it's
been a minute since I had a guest video. I'm hoping that 2021, that I can really pick up
the pace here. I have a goal of having at least one guest video per month and what's
a better time to start than March. Now, in case you've missed some of the other guest
conductor videos, I featured a 3D modeling live stream from Chrissy Brimmage, a cozy
coding session with Aaron Davey and a video by Amigoscode. And you can find all of these
in the Guest Conductors playlist on the coding train. Today I am so excited to feature a
video from LeeLee James. LeeLee is channeling her engineering education, dance training,
and resourcefulness through queer, femme and black identities into a wild and wonderful
YouTube series, Twirling Tech Goddess. As a Computer Science Major, LeeLee encourages
radical diversity and inclusion by making the process of learning tech more fun, accessible
and relatable to people underrepresented in STEM. So the very first thing that you should
do right now, and I'll put up a card and maybe an animation to remind you, is go and subscribe
to the Twirling Tech Goddess. Subscribe, click the notifications button, you don't want to
miss any time LeeLee releases a new video. Now, to be honest I had a pretty hard time
picking which video of LeeLee is to feature and show here on the Coding Train. They're
all amazing and I think the word I should really use here is fabulous, but I've settled
on one and it is called, 3D Printing, a Motorized High Fashion Hat. I don't talk a lot about
hardware or 3D or fashion on the Coding Training. And this is really one of the main reasons
you should make sure to also subscribe to Twirling Tech Goddess. You really wanna round
out your YouTube education. LeeLee's creativity and using a combination of 3D printing alongside
opensource models is really aligned with the Coding Trains goals of making technology approachable.
As part of this video and thank you to LeeLee James for introducing to me to this wonderful
organization, Coding Train is making a donation to Queer Asterisk. A Colorado based 501 non-profit,
providing queer-informed counseling services, educational trainings, and community programming.
I'll include a link to the Queer Asterisk website, in this video's description, where
you can learn more and make a donation if you'd also like to support them. But we are
here to see the Twirling Tech Goddess. I will note this is a reposting of an existing video
on her channel. So what I'd really like you to do, as strange as this might sound, is
stop this video right now, pause this video, there's a link in the description, a card
will pop up, go and watch it over on her channel. If you choose to stay that's okay too. The
video will play. You'll get to experience it, but whatever you choose, make sure you
subscribe to the Twirling Tech Goddess, turn those notifications on, you don't want to
miss a video. I am so honored to be able to share this YouTube channel with you. You're
in for a real treat, if you haven't experienced it before. And I hope to see you in a future
Coding Train video.
- Hi inventors. I'm LeeLee, the Twirling Tech Goddess. I'm black, I dance, I'm queer, and
I'm an Engineer. Welcome to the Twerk shop. A show that explicitly encourages radical
diversity and inclusion by making the process of learning tech, more fun, accessible and
relatable to people underrepresented in STEM. Each month you'll come along with me as I
create something fabulous using cutting edge tools and technologies, then I'll put it through
my patented Twirl Test to make sure that it's stage ready. That's right. We twirl with our
tech because you know what they say, the family that slays together increases their socioeconomic
status together. On this episode, we're gonna be making a motorized headpiece using one
of my favorite technologies, 3D printing. I'll walk you through the hardware and software
that we'll be using for the production and design of the headpiece. And then I'll introduce
you to the motorized element that we'll use to make it move and spin. A little backstory,
when I was on tour as a figure skater, a French compatriot of mine noticed that, anytime I
saw something cute in a shop, I would hold it up to my head like so. So, fall semester,
I'm walking through the bookstore on campus here, and I spot a little heart that's like
moving in and I knew I needed to have it on my head. So I asked the sales clerk, where
can I get one of those? And I basically blacked out as he spotted off all this information
about how to make it. And I had no idea what he was talking about. So here we are two semesters
later and I finally have the tools and skills to make it happen. So let's get started. So,
this is a 3D printer. This one belongs to the school and it was about $2,000. This one
belongs to me and it's a 10th of the price and a lot less cumbersome. So this one doesn't
even work. So let's get this raggedy piece out of here and get to work. This is the bed.
It gets hot. This is the extruder. It gets hotter. This is the filament you'll use, and
you feed this filament into the extruder. It melts it, drips it on the bed, makes the
3D print. It's amazing. There's multiple ways to get the image to the extruder via this
processor. One of the ways, is using an external SD card. You can also connect it directly
to your laptop using a USB cable or your desktop. Stick the landing. When it comes to 3D printing,
you first need the document that you want to print, much like any 2D print job on a
paper printer you can print a pre-existing document or you can create your own document.
We'll touch more on creating 3D models in a future video where I'll be creating my own
high heels. Today however, we'll be using a pre-existing document to create a motorized
headpiece. The documents have authors and those authors are published as specific sites.
Sites such as Yeggi and Cults 3D, have 3D prints that authors, artists, creators post
for sale. If you purchase the right 3D printer, however it may in fact, come with some complimentary
exclusive 3D models designed by excellent designers for that specific brand, such as
Ultimaker. There are also document libraries of sorts that offer open source free download
of preexisting document models, such as Thingiverse, which is hands down the most popular, and
the one we'll be using for this project. Now let's go over to Thingiverse and download
the gear heart document. Link in the description, these downloads come in various types and
you'll want to look for the dot STL file to download that one. There are other file types,
but for now we'll just focus on our dot STL files. Next, we'll download a 3D printing
app. Think of this as our print preview for this project I'll be using Cura. Link in the
description below. From inside Cura, we'll import our Dot STL file. This takes our 3D
model and slices it creating a new render that can be printed layer by layer. Now let's
get the document to the printer and let the printer do its thing. First, I
printed a prototype and I'm glad I did because this specific print had an enclosed bottom
and I needed an open bottom for the motor after finding the parts that better suited
my needs and removing the parts that didn't. I merge those files and made a second print
which is the one that I provided for y'all link in the description. And now let's talk
post production. So depending on the PLA you use, you may or may not need or want to smooth
the surface of your print. As you can see up-close, prints leave layer lines. So to
smooth that surface you may want to use sandpaper to get rid of some of those lines. And you
can also soak your piece in acetone or nail polish remover. Once you've done that, you
could also prime the surface with a plastic dip or primer. If you gonna paint on top of
it or adhese any glitter or be dazzling effects. So this is your motor, it's a few bucks, link
in the description. You can just get these on Amazon, super simple. You power it and
it spins. This is gonna be our external power source, it's a battery pack four batteries
go inside, you can get these in the size of three batteries. This four batteries is six
volts. Three batteries is gonna be four bolts and two batteries is three volts. The thing
that I love about this is it also has this handy-dandy on-off switch so we can turn it
on and make sure we have power, if we see a little spark we know that this is working.
So I'm gonna use these alligator clips available at any hardware store, these are a few bucks.
So that I don't actually have to touch the wires, now that they're live and I'm gonna
connect one of those to each of the rivets on the motor and boom. Oh. Super handy. So
now you'll get the idea, if I take the fan piece off, pop the head piece on Houston,
we have lift-off. To turn this into a headpiece, we're gonna need a few things, essentials.
Handy dandy glue gun and glue sticks. Your favorite pair of scissors, your least favorite
head man, and a small tupperware with lid. And keep your motor nearby. So we're gonna
build from the bottom up, it's my strategy. So I take the head man, which is gonna rest
here on my head and we're gonna glue the bottom or the base of the tupperware onto our headband.
And that will house the motor and then we'll put our lid on the motor and then hot glue
our headpiece onto the lid. Which will allow the motor to stay weatherproof inside. Let's
get started. ♪ Soon it will be, better better ♪ ♪ It will, be better oh yeah ♪ ♪ Soon
it will, be better better better better ♪ ♪ Soon it will, be better ♪ So now that this thing
is fully assembled, I'm already thinking of finishing touches and embellishments that
I want to make to cover the head man and cover the tupperware, and I invite you to play and
have fun with your finishing touches and embellishments. Please share your photos and videos of your
creations down in the comments below, and they better not look like mine. Now let's
take this head piece for a twirl. A wearable isn't useful to me if it's not stage-ready.
So I'm gonna go get changed and I'll see y'all on the mountain. ♪ I love I love ♪ ♪ I
