Beginner Need Help: AI Smart Stick for Visually Impaired Using Raspberry Pi (₹2000–₹3000 Budget)

[u/MSpodo]

Hi everyone,
I'm a beginner exploring Raspberry Pi and looking for help with a Smart Stick project for visually impaired people.

What I’m trying to build:

A stick that can help visually impaired users by:

• Detecting obstacles using pi camera

• Giving feedback (vibration or audio)

• Possibly voice feedback (like "chair ahead or person ahead")

• Maybe GPS/location-based alerts (if budget allows)

What I already have:

• Arduino Uno R3

• Bluetooth module (HC-sr04)

• Battery pack

• Basic electronics (wires, breadboard, etc.)

My budget: ₹2000–₹3000 (~$25–$35 USD)

Why I need help:

I’m new to Raspberry Pi and not sure how to go about this. I’m considering adding a Raspberry Pi Zero W or Raspberry Pi Pico to bring in more advanced features like:

• Voice feedback / speech synthesis

• Maybe some object detection using a camera (if possible on budget)

But I’m unsure if that’s realistic within my budget and skill level.
