I had some spare time and moved on with the software mods on
The mods are:
- display is always on (means
you need to power by NiMH or wall supply)
- small animation after reset (test
all the LED's)
- small animation at full 5' (solid) minutes
to distribute/publish the mods if you feel appropriate.
The sketch is available for download here.
Thank you Gerard. Keep up the great work!
