# FireFly Solar / 日輪蛍

**Nichirin Hotaru**  
*A small solar-powered Morse firefly for the outdoors.*

**太陽を宿し、夜にモールスを灯す蛍。**  
*Taiyō o yadoshi, yoru ni Mōrusu o tomosu hotaru.*  
*A firefly carrying the sun, lighting Morse in the night.*

## Overview

FireFly Solar is a small outdoor LED blinker inspired by the idea of an LED throwie, but powered by sunlight instead of a disposable coin cell.

During the day, the solar cell charges the energy storage.  
At night, the circuit wakes up and sends a simple Morse-style light signal.

The project is partly a small garden object, partly a low-power electronics experiment, and partly a design exercise for future DIY kits.

## Project Goals

- Build a solar-powered outdoor Morse blinker
- Keep the hardware simple and robust
- Improve practical low-power design skills
- Test mechanical concepts for outdoor 3D-printed parts
- Learn what is needed to turn a small electronics project into a possible DIY kit

## Naming

The English project name remains:

**FireFly Solar**

For blog posts, documentation, and presentation, the project also uses the Japanese name:

**日輪蛍 / Nichirin Hotaru**

The name roughly means **sun-disc firefly**. It keeps the solar theme, adds a slightly mythic tone, and still fits a small piece of outdoor hardware.
