Week 16 – System Integration
This week is about combining different subsystems, components, or applications into a unified functioning system..
The objective is to finalize User Workflow, Electrical Diagram, Flow-Chart, System-Diagram and finally make a Mock-up of my final project.
AI prompt: "Please give an animated avatar of my self working on user flow diagram, block diagram, flow-chart of my project and doing mock up for my device casing fixing the components and fixing Bill of material and finalizing what process I will follow which machine I will use to make particular part of my project. please give landscape image. "

Contextualization
The Cultural Context : Navratri is a high-energy, multi-day Indian folk festival centered around folk dance steps. Participants wear vibrant, traditional attire and move in synchronized circles to rhythmic music. The Bheru outfit digitizes this tradition. It turns the garment into a "living" part of the performance that reacts to the music and helps people stay connected in a crowd.
The Technological Context : The Project sits at the intersection of Electronic Textiles and Wireless Communication.
- Interactive Aura : I2S Microphone and Embroidered Neopixels for audio-reactive vibrant outfit.
- BLE Control (Mobile App) : giving the user personal control
- Friend-Finder (GPS + LoRa) : helps people stay connected in a crowd or find a new fried using Long Range (LoRa) radio for large-scale outdoor festivals where mobile networks often crash.

Sketching (Form & Function) - exploded sketch
Mock ups (cardboard and glue) - Scale, proportions, form, actual component dimensions
System Diagrams
User FLow Diagram
Functional Block Diagram
System Diagram
BOM
Mobile App
Programming
Programming Logic
Microcontroller/microprocessor - resource availability check (research)
FastLED configuration code
Packaging
Enclosure Design - DFM compatibility (3D printing?, laser cutting,? machining?)
Mounting, modularity - Screws , glue, threaded inserts , snap fits,
Wiring and connectors
Electronics Integration - PCB, sensors, actuators, battery, etc..
Testing methods
Washing
Expected failures
Microphone inside or outside? - Exposed to Environment to capture soundbites
Magnetometer Location in PCB? Magnetometer Orientation?
Booster 3.7V to 5V and IN5408 Diode, to make 3.3 signal in-out work.
GPS Module Thickness - Using Mobiles GPS instead
Heaviness of module that it may fall or slag - validate weight
Copper touch response on cloth or in the badge - Removed this feature
Can this be done? first leaser cut and then print?
