🔋 DIY Battery Pack
A simple sixth-grade electronics project that repurposed a 12V car USB charger circuit into a homemade portable USB power source inside an Altoids tin.
Early Electronics
Power Conversion
Soldering
Repurposed Hardware
Overview
This was one of my earliest hands-on electronics projects. I built a small portable battery pack using an Altoids tin, a 9V battery, and a repurposed USB charger circuit.
What I Learned
- How to take apart electronics and reuse components
- Basic power conversion concepts
- How circuits, batteries, and outputs connect together
Reflection
This project was simple, but it sparked my interest in engineering and building real systems from scratch.
