-## 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.

+The English project name remains:
 
----
+**FireFly Solar**
 
-## Hardware
-- **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)
+For blog posts, documentation, and presentation, the project also uses the Japanese name:
 
----
+**日輪蛍 / Nichirin Hotaru**
 
-## Firmware / Arduino IDE
-- 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.
+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.

+ Version: 0.1 - Attiny85 Version
+ Date   : 25.05.2026

+
+ Inspired by Karl Lunt's FireFly project I wrote some code to make this
+   Throwie lasting longer, blinking only at low light levels and morse also
+   some text.
+   http://www.seanet.com/~karllunt/fireflyLED.html
+
+ How it works (only the Morsethrowy part):
+   LED detects light level, using bleeding out time of LED pn-capacitor.
+   If dark enough blink a text in morsecode (ATTiny45 = 22 Chars, text will 
+   be defined in line 191/192 of this file)
+   To save energy go to powersave mode after blinking or light level is
+   over threshold. Tests this every 8s (maximum time for watchdog timer 
+   possible for ATTiny). Repeat this endless
+   
+ 
+     The wiring, it's very simple, see also HW part of the Project.

+ Powersaving Mode for Attiny45/85:
+   A good description by Martin Nawrath nawrath@khm.de and the folks at
+   http://www.insidegadgets.com/2011/02/05/reduce-attiny-power-consumption-by-sleeping-with-the-watchdog-timer/
+   
+   With this description I got ~5uA during sleep mode.
+   in Morse-Mode with LED OFF: 1.7mA 
+                      LED ON:  6.9mA
+   --> I hope to run this throwies ~40days with one CR2032.
+
+ Morsecode
+   To translate a text into morsecode, there are several ways. You can use
+   this fine online translator:
+   http://morsecode.scphillips.com/jtranslator.html
+ 
+   There is also a great morse coder / encoder from Matthias Esterl aka madc.
+   Works fine for Arduino, but not for ATTiny because of RAM limitations. But
+   maybe this is helpful if your project works with an Arduino.
+   https://gist.github.com/madc/4474559
+
+   For this project I use a simple case structur. Looks arkward, but the
+   ATTiny45 has only 256byte RAM but 4kFlash. A data structure is better programming
+   but needs a lot of RAM we not have. Therefore this ugly case structure.
+   This will waste the flash memory but we have enough and saving RAM for
+   our payload - the ASCII-string with the morsetext.
+ 
+ BTW - Morsecode itself:
+   
+     'A', ".-"      'B', "-..."    'C', "-.-."
+     'D', "-.."     'E', "."       'F', "..-."
+     'G', "--."     'H', "...."    'I', ".."
+     'J', ".---"    'K', ".-.-"    'L', ".-.."
+     'M', "--"      'N', "-."      'O', "---"
+     'P', ".--."    'Q', "--.-"    'R', ".-."
+     'S', "..."     'T', "-"       'U', "..-"
+     'V', "...-"    'W', ".--"     'X', "-..-"
+     'Y', "-.--"    'Z', "--.."    
+ 
+     '1', ".----"   '2', "..---"   '3', "...--"
+     '4', "....-"   '5', "....."   '6', "-...."
+     '7', "--..."   '8', "---.."   '9', "----."
+     '0', "-----"
+   
+     '.', ".-.-.-"  ',', "--..--" '?', "..--.."
+     '!', "-.-.--"  ':', "---..." ';', "-.-.-."
+     '(', "-.--."   ')', "-.--.-" '"', ".-..-."
