Electronics Project

Bench Power Supply

A practical bench power supply project designed around a buck converter, fuse protection, active cooling, panel components and a custom 3D printed enclosure.

Electronics Power Supply Fusion 360 3D Printing Hardware

Overview

Project Summary

This project is a custom bench power supply built for testing small electronics projects, DC motors, modules and circuits. The goal is to create a practical, compact and usable power supply instead of relying only on loose adapters and temporary wiring.

The system is based on a buck converter module and includes panel-mounted connectors, fuse protection, cooling considerations and a printed enclosure. It is also a project for improving my practical electronics, wiring, soldering and 3D design skills.

Purpose

Why I Built It

I wanted a cleaner and safer way to power small projects while learning how real electronic systems are planned, protected, mounted and documented. Instead of leaving components scattered on the desk, I designed the project as a complete usable device.

Project Features

Key Features

This section highlights the important parts of the project. The same structure can also be used later for software, game development or design projects.

Adjustable Output

The power supply is planned to provide adjustable DC output for testing different small electronics projects, modules and DC devices.

Fuse Protection

Fuse protection is included to reduce risk during faults, incorrect wiring or accidental short conditions.

Active Cooling

Cooling is considered to keep the internal module more stable during longer use or higher load conditions.

Custom Enclosure

The enclosure is designed for 3D printing and helps turn loose electronics into a cleaner and more usable device.

Panel Layout

The front panel is planned for output connectors, controls and display elements in a practical layout.

Documentation

The project page collects explanations, design decisions, files and visuals in one place.

Build Notes

Development Notes

Notes about the decisions, limitations and improvements discovered during the build.

01

Design Approach

I focused on making the project physically usable, not just electrically working. That means enclosure design, panel placement and wiring layout are part of the project.

02

Safety Considerations

Since the project handles power delivery, protection and wiring choices matter. Fuse placement, connector quality and heat management are important parts of the design.

03

Learning Outcome

This project helped me practice practical electronics, 3D modeling, enclosure planning and documenting a hardware project in a more organized way.

Next Steps

Planned Improvements

A short list of what I want to improve or document next.

→

Add real photos of the printed enclosure and internal wiring.

→

Add voltage/current test results after final assembly.

→

Upload or link enclosure files, diagrams and documentation.

→

Write a clearer explanation of the final wiring and protection logic.
