The Final Project

Problem
Long hours at a desk or lab can silently damage your posture. Poor alignment affects the spine and ribcage, causes certain muscles to become inactive while others are chronically overworked — leading to pain, discomfort, and long-term injury.

Solution
A lightweight wearable device that corrects posture in real time by tracking two fixed points on the shoulders. By monitoring shoulder alignment, the device guides the neck, back, and core into a healthier position — making good posture feel natural and comfortable. Over time, it trains the body-mind connection so correct posture becomes automatic.

Experince

As a 200-hour certified yoga instructor with a background in body mechanics and mobility anatomy, I understand posture from the inside out. Being part of the Fab Academy network gives me the tools to actually build this — and I'll be the very first one to wear it.

Charging Case	The case to keep the clipper with wireless charging functionality	Laser cutting	MPF wood	Parametric design
Main Circuit Board		PCB Milling	FR1 Copper Board	Electronics production

The process

This would be the results of each weeks assignments.

Ideation: Wearable vest with sensors and vibraion

01 | Creating building block to make up the main fabric for the vest. I'm planning to keep the wiring all hiden while its being printed

02| Defining the areas to keep the gyro sensor specially the soldres, the neck , spine, chest and core

03| A wireless charging station

04| As I'm progressing during the week and get more exposure with my colleges projects, I try to simplify the project. I created a design with a fliaxble strap but wiring was an issue

05| My other design to to make a wireless connected sholder pads that can communicate with each other and can be stable on the sholder. either directly on the skin or on top of the cloth

06| reghargable station is nesessary for this kind of project and Im looking at different ways to create both a case and a charger inspired by my DJI Mic

Good Enough for now

Feedback:The excitemnet in the begining made me create and imagine alot to be done. the more I progressed the more I kept on simplifying the projects. Now I defined the point where I will start my spirale development of the projects
Challenge: The recharging case is challanging

Part 01: Shoulder Clips

01 | The mian curcit will be in a small box that can be placed inthe sholdre

02| It can be fixed by clip or magnet

03| There will be additional magnets under the case to kep the Shoulder clips in place once they are in the charging case

04| The main parts for each clip ESP32-C3-SupperMini MicroController → MUD-GY-512 → Vibration Motor and those will be programing using C++ or MicroPython

06| This is the drawing of the main parts on the board which can also be designed as a flixy PCB with Copper Tap and 3D printed board

07| I also found a way to design the rounts and wires in the 3D design as demnetstrated here

07| But I decided to start with a flat hard fixed PCB and then spiral my way to wireless charging and then a flixy curcit and

07| This is the rearranged PCB designined created with Kicad

Good Enough for now

Feedback:The excitemnet in the begining made me create and imagine alot to be done. the more I progressed the more I kept on simplifying the projects. Now I defined the point where I will start my spirale development of the projects
Challenge: The recharging case is challanging, PCB is still a challange

Part 02: Charging case

01 | The chargable case will be small and flat to fit in to a bag

02| There should be placeholders for the clips to fit in

03| The case should be holding all the parts and accessories

05| wireless charging sensor
