IgnisLink

A remote firework ignition system controlled through your smartphone — built to ignite fireworks safely and precisely, even in harsh weather.

Overview

IgnisLink is a project I built about two years ago. It’s designed to ignite fireworks remotely using your phone from a safe distance. In Sweden, fireworks are typically used only on New Year’s Eve, and weather can make lighting them tricky — especially in heavy rain.

Instead of trying to time the fuse perfectly to ignite at midnight, IgnisLink lets you press a button on your phone exactly at 00:00 — and fire the firework instantly and reliably.

How It Works

The system uses a small ignition box with an internal igniter that activates on command from your phone. The main goals were:

• Keep the user at a safe distance
• Guarantee perfect timing (exactly at midnight)
• Work in rain, snow, and cold Swedish winter conditions
• Provide a simple “press to ignite” interface

Improvements I Want to Make

The project is not fully finished, and although I paused it, these are things I want to fix:

• A reusable igniter instead of a single-use one
• A more compact ignition box
• A small antenna to increase communication distance
• A proper mobile app with customizable interface

What I Learned

IgnisLink taught me about wireless communication, ignition circuits, weather-proof design thinking, user timing precision, and how to plan a hardware product that interacts with a mobile interface.
