|
||||
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.
|
||||
## About this Project
|
||||
|
||||
FireFly Solar is my **technology playground**. It is a small garden object, but its real purpose is to learn by building something complete. With it I learn about:
|
||||
|
||||
- **Circuit design at the edge**: in this case, as low power as possible
|
||||
- **PCB design**
|
||||
- **Weatherproof casing**
|
||||
- **ATtiny programming**
|
||||
|
||||
Possible next technology step: everything about DIY SMD design and soldering.

|

- Test mechanical concepts for outdoor 3D-printed parts
|
||||
- Learn what is needed to turn a small electronics project into a possible DIY kit
|
||||
|
||||
## Software
|
||||
|
||||
The firmware runs on an **ATtiny85** at 1 MHz (internal clock, ATTinyCore: `clock=1internal`, `millis=disabled`). The LED itself is used as the light sensor. When it is dark, the firefly sends a short Morse text ("TGO 26") about once a minute.
|
||||
|
||||
### Current Firmware version: v0.4 (2026-11-08)
|
||||
|
||||
Goal: lowest possible average current.
|
||||
|
||||
Changes vs v0.3:
|
||||
|
||||
- No `delay()` / `millis()`; Timer0 and Timer1 are gated off in PRR.
|
||||
- The watchdog (interrupt mode) is the only timebase: Morse units (~96 ms), the sensing window and the 8 s sleeps. The CPU sleeps in power-down in between.
|
||||
- Darkness sensing: the CPU sleeps in 16 ms steps while the LED junction discharges, instead of a busy `digitalRead()` loop. Bright light exits after the first step. `darknessThreshold` is replaced by `darkSteps`.
|
||||
- The ADC is disabled before it is gated off in PRR; pins are set up before PRR.
|
||||
- After a power-on or external reset, no blinking for `RECOVER_CYCLES` (about 16 min), so the supercap can recharge.
|
||||
- `DEBUG_TEST` switch for bench testing: 8 s cycle, no recovery wait, short flash when the sketch decides "bright". Set it to 0 for the field.
|
||||
- Optional `BOD_FUSE_ENABLED` (BOD off during sleep); unused with the BOD fuse off.
|
||||
|
||||
Tested: compiles with ATTinyCore and runs on hardware. Current draw is not yet measured.
|
||||
|
||||
## PCB
|
||||
|
||||
- Finished: a batch of 10 is assembled, tested and working.
|
||||
- Latest adjustment: fine-tuned the resistors for the LED, and the 3.9 V Zener diode is confirmed safe avoid overcharging 4V supercap.
|
||||
- Next version: the PCB should be a little shorter. The wiring space is a bit too tight now.
|
||||
|
||||
## Casing
|
||||
|
||||
Works basically as intended. Lessons for the next version:
|
||||
|
||||
- Better locking of the solar modules.
|
||||
- The rope structure works, but building it is too complicated and takes a lot of nerves.
|
||||
- Using material tension to secure the modules via rope was basically a good idea.

Date : 2026-11-10
|
||||
|
||||
- Removed unnecessary ADC enable/disable from loop()
|
||||
- Disabled ADC and analog comparator in setup()
|
||||
- Added INPUT_PULLUP for unused Arduino pins 0, 1, 2 will save power
|
||||
- Added safer watchdog setup with interrupt protection to save run near brownout
|
||||
- Added wdt_reset() before sleep for cleaner 8 s timing
|
||||
- Added lowercase-to-uppercase handling
|
||||
- Unsupported characters are now ignored without adding fake timing gaps
|
||||
|
||||
Key changes Version 0.5 (goal: lowest possible average current):
|
||||
|
||||
- No delay(), no millis(): Timer0 and Timer1 are not needed any more and
|
||||
are switched off in PRR.
|
||||
- ALL timing (Morse units, sensing window, 8 s sleep) is done by the watchdog
|
||||
in interrupt mode while the CPU is in POWER-DOWN. The CPU runs only for a
|
||||
few microseconds per wake-up. LED pins keep their state in power-down.
|
||||
- Darkness sensing by LED no longer polls digitalRead() in a busy loop (that was
|
||||
~0.3-1 s awake per cycle). The LED junction is charged, then the CPU sleeps
|
||||
in 16 ms steps and checks the pin: bright light exits after the first step.
|
||||
- ADC is disabled BEFORE it is gated off in PRR (order matters).
|
||||
- After a power-on, external, brown-out or watchdog reset the sketch waits
|
||||
RECOVER_CYCLES cycles before blinking, allowing the supercap to recharge.
|
||||
Default ~13 min 20 s (nominal); the debug option bypasses recovery.
|
||||
- Startup code saves MCUSR and disables the watchdog early (.init3), avoiding
|
||||
a watchdog-reset loop before setup() can execute.
|
||||
- Optional: BOD disable during sleep (only useful if BOD fuse is enabled).
|
||||
But found out that also BOD Fuse for 1.8V shorten unnecessary blinking time,
|
||||
will still work ~1V, meaning ~20 min longer blinking time.
|
||||
- Field Test: After a sunny day in Winter, outdoor -1 ... 8°C, with a payload
|
||||
of 10 signs) it blinks for >> 12h.
|
||||
|
||||
Timing note: the watchdog oscillator is not precise (changes with Vcc and
|
||||
temperature). All Morse timing comes from the same clock, so dit/dah/gap
|
||||
ratios stay correct; only the absolute speed drifts a little.
|
||||
The HW actual allowes 5V and 3.3V, standard is 3.3V. So don't expec exact timing.
