UNEB Science Project 2025 — Wacha Ryan Braston

About Me

I am Wacha Ryan Braston, a 16-year-old student at St. Joseph’s S.S.S Naggalama. My 2025 UNEB Science Project, titled “DIY Mini Fan for Affordable Cooling,” addresses the challenge of unaffordable cooling systems for rural students while serving as an educational tool for electric circuits.

Project Overview

• Duration: 17th July 2024 to 13th March 2025
• Theme: Skills and Innovation for Sustainable Living (UNEB)
• Summary:
  The project involves building a low-cost mini fan using locally available materials, demonstrating electric circuit principles and practical skills.

Objectives

• Build a working mini fan using local materials.
• Demonstrate electric circuit knowledge.
• Develop skills in cutting, gluing, wiring, and assembly.
• Meet UNEB project standards.
• Mitigate heat effects during the day.

Hypothesis

A DC motor powered by a lithium cell through a switch, fitted with a rotor, can function as a low-cost fan, generating airflow.

Results

• Produced effective airflow, portable and efficient on low voltage.
• Stable design suitable for cooling or educational use.

Challenges

• Limited battery power required higher-capacity cells.
• Initial rotor imbalance needed design adjustments.
• Loose wiring required reattachment for consistent power.

How It Works

The fan uses a simple circuit: a lithium battery powers a DC motor via a switch. When turned ON, current spins the motor’s rotor, creating airflow. This demonstrates energy conversion from electrical to mechanical.
