# ToGo-Lab FireFly Morse Blinker # FireFly Solar / 日輪蛍
**DIY kit**: ATtiny-based Morse blinker. Through-hole. No mains. Simple on purpose. **Nichirin Hotaru**
**Default license**: [CC-BY-NC-4.0](https://creativecommons.org/licenses/by-nc/4.0/) *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.*
## Intro ## Overview
This is my “Hello World” hardware project on the new ToGo-Lab server. 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.
Years ago I built a tiny Morse throwie: ATtiny + one LED + one resistor, plus firmware. This version adds a supercapacitor and small solar cells. It uses the LED as a light detector, so it only blinks in the dark. During the day, the solar cell charges the energy storage.
At night, the circuit wakes up and sends a simple Morse-style light signal.
It's not a throwie anymore. Hang it anywhere with decent light (for charging) and dry conditions and let it blink Morse on its own during night. The project is partly a small garden object, partly a low-power electronics experiment, and partly a design exercise for future DIY kits.
Goal: a beginner-friendly DIY kit with clear docs and hackable firmware. ## Project Goals
Checkout also the [blog about this project](https://https://togo-lab.io/?p=82). - Build a solar-powered outdoor Morse blinker
ToGo-Lab Cloud [link](https://nextcloud.togo-lab.io/index.php/f/1176), actual internal link only. - Keep the hardware simple and robust
Suggestions welcome. Open an issue or email [tgohle@togo-lab.io](mailto:tgohle@togo-lab.io). - 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
## Repo layout The English project name remains:
```
0001_FireFly/
├─ KiCad/ # .kicad_pro, schematic, PCB, fabrication outputs
├─ CAD/ # 2D/3D mechanical drawings, panel outlines (if any)
├─ Program/ # firmware source, hex, Makefiles / Arduino sketches
└─ Documentation/ # assembly guide, quick start, FAQ, photos, BOM CSV
```
--- **FireFly Solar**
## Hardware For blog posts, documentation, and presentation, the project also uses the Japanese name:
- **MCU**: ATtiny45/85 (internal RC clock, no crystal).
- **I/O**: 1× LED + series resistor. Unused pins broken out to breadboard-style pads.
- **Burning Attiny**: external ISP programmer via Arduino IDE; PDIP-8 ATtiny45/85 footprint.
- **Power**: 3V DC (coin cell & & solar cell + supercapacitor with Schottky diodes to extend battery power).
- **Safety**: low voltage only. Observe polarity.
- **PCB**: hackable; access to unused ATtiny pins. (big pads for beginners, clear silks, LED polarity marks)
--- **日輪蛍 / Nichirin Hotaru**
## Firmware / Arduino IDE 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.
- Follow `Documentation/ToGo-Lab_FireFly_ArduinoIDE_Program_Guide.md`.
- Board core: any stable ATtiny45/85 core.
- Clock: **internal**. No fuse change required for first tests.
- Programmer: USBasp / AVRISPmkII / Arduino-as-ISP.
- Open the sketch in `0001_FireFly/Program/`.
---
## Assembly
- Follow `Documentation/ToGo-Lab_FireFly_Assembly_Guide.md`.
- First power-up: LED should blink test pattern. If not, recheck polarity and bridges.
---
## Test / Bring-up
1. Visual check; no shorts.
2. Power at 3–5 V. Current < 10 mA idle.
3. Program firmware over ISP.
4. Verify Morse timing; adjust WPM in `config.h` if needed.
5. Optional: measure current.
---
## BOM
- Follow `Documentation/ToGo-Lab_FireFly_BOM.csv` as source of truth.
---
## Files to fabricate
- Gerbers and drill files from `KiCad/fab/` (board house-ready).
- Project file: `0001_FireFly/KiCad/ToGo-Lab_FireFly.kicad_pro`.
---
## Known constraints
- Through-hole only. No reflow.
- Minimal I/O to keep it beginner-friendly.
- Low power is nice but optional; optimize after the basic release.
---
## Roadmap (tech only)
- v0.1-proto: breadboard + first PCB, single message, speed presets.
- v1.0: build guide, BOM with alternates, pilot 10 units.
- v1.1: docs polish, optional brightness setting, minor PCB tweaks.
