My Final Project example

I really wanna work on something that belnds electronics and mechanics

Research

couple of ideas

real life mario kart with REAL karts or rc cars.

Research revealed very complex not so many sources of executing something like this

3D hologram fan, camera input and maybe sound

The fan blades rotate at an incredibly high speed, typically ranging from 500 to 2,000 revolutions per minute (RPM). As the blades spin, they display individual frames of the holographic image, making it appear as if the hologram is floating in the air.

Parts needed-

BLDC Motor – High-speed motor to spin the display (Persistence of Vision).
Motor Driver / ESC – Controls the speed of the brushless motor.
LED Strip (WS2812B / SK6812) – Addressable RGB LEDs mounted on the rotating arm.
Microcontroller (ESP32 / RP2040 / STM32) – Processes image data and controls LED timing.
Rotation Sensor (Hall Sensor / Optical Sensor) – Detects blade position for accurate frame display.
Magnet – Used with the hall sensor to detect each rotation.
Slip Ring – Transfers power to the rotating LED arm.
Power Supply (5V / 12V) – Provides power to motor and LEDs.
Storage (MicroSD / Flash) – Stores image or video frames.
Custom PCB Blade – Holds LEDs and electronics on the rotating arm.
Bearings / Shaft Mount – Stabilizes the rotating assembly.
Housing / Frame – Structural enclosure and safety protection.
