PROJECT DEVELOPMENT OF S H O W S A C K

🌟 MY PRETTY Project Overview 🌟 The SHOWSACK is a fabulous, motorized backpack designed to enhance outfits with dynamic movements, perfect for drag queens and fashion designers who want to elevate their ensembles. This project brings together a range of skills from 2D and 3D design to electronics and system integration, creating a truly unique and dazzling accessory.

🌸 Project Questions Answered 🌸

What does it do?

The SHOWSACK moves accessories attached to the backpack using servomotors, all controlled by a chic embedded microcontroller. It features multiple movement modes that can groove to the beat of your music or be controlled via WiFi.

Who's done what beforehand?

While there are other projects with motorized elements and wearable tech, none quite match the glam of SHOWSACK. Inspiration came from a fellow Fab Academy student and various LEDlit backpacks, but nothing else shines quite like this.

Soooooo This particular backpack maybe can be put in here because of the output situation it has going on (kinda like my servos) and wifi access point controls:



• Cool Backpack with leds

And also take a look! it has a QR situation going on! just like mine awww

Where did the idea came from sis?🌈🔥

❥So, here in Mexico we have a Drag Race of our own, kinda like Ru Paul´s Drag Race but Mexa.

❥It is called La Mas Draga and here you can see the kind of costumes these gurls pull off, that's why I wanted a structure that could move in 4 axis, because I really want to dress them one day!

What did you design?

I designed the backpack structure, servo mounts, and the electronics setup. The design includes 2D and 3D elements, ensuring everything is lightweight, functional, and fabulous.

Structure

Now, I've gotta design and build the structures that the servos will move. Thinking about how to make it look fab and not too heavy is key.

• So, the back of the Showsack is where all the action's at. We're talking four servos, one in each corner. These little guys are moving whatever we hook up to 'em in the accesories attachments. The servos are hooked up to this ESP thing, which tells 'em what to do. It's like the brains behind the operation. Each servo gets mounted in a corner of the backpack in different heights, nicely so they can do their thing without wobbling around.

I NEED TO: Define size and slots, infuse with foldable grooves. Craft a LiPo battery compartment with precision, adding PCB holes and mounting four servos. Prepare foam layout, remove excess, and construct cover with flair.

How does this work gurl? Give me sum details

So let me tell you about how the magic happens through the synchronized dance of this four Tower Pro MG995 servomotors:

• These motors have a specially designed 3D-printed attachments that snap right in, allowing you to insert any material you want to animate.

• With three fabulous modes that you can switch between with just a button, everything is controlled by an ESP8266 12F microcontroller with built-in WiFi.

• The inspiration behind this creation comes from the electrifying performances of drag queens, syncing perfectly with the rhythm and lyrics of their music. I researched the most popular beats and crafted three unique servo movements to groove along with them.

• The base and the chic attachments are all made using 3D printing technology.

• To ensure the backpack straps don’t put too much pressure on the wearer, I designed a Y-shaped mold for the intersection of the three straps on the chest using 3D printing, then casted it with silicone. This brilliant move has made the backpack incredibly comfortable.

• Also I laser cut this eva foam cushion for the back of the device to give so much more coooooommmmmfort in the user´s back.

• For this personal project, I filled the cute motor´s attachments with black feathers to test its fabulous capacity hole setup.

❣️🍓ALL ABOUT THE DESIGN 🍓❣️

Soooo here´s the T honey bee..

I used Catia for this design because I just love this software, it´s so much easier, here´s all about the design bae step by step

• THE CODE

Planning

First things first, I'd sketch out what parts I want to move and how I want them to move. Do a little brainstorming and figure out what the backpack is gonna look like. Also it was super important to use everything I learned here, of course I couldn´t use everything but it ended up looking 🎀✨gorgeous✨🎀.
