One fleeting visitor was a Stock Dove. I haven't seen one of those for months so this was a welcome sighting.
Not quite so welcome was an early morning visit from a Sparrowhawk. This one was sat on the back of an old wooden chair right next to the Birdy Bistro. What I particularly noticed was the way it had its darker back facing outwards which made it blend in better with the fence in the background.
As soon as it spotted me it flew away to hunt for breakfast elsewhere.
Only a little further with the rain gauge project. Added the ability to switch off the lCD readout in software. The collector is now outside and the electronics in the conservatory while I see how well it works. 3 mm rain recorded yesterday, 4 mm so far this morning.
The unit uses a 9V wall wart power supply but also automatically changes over to a battery during any power interruption - a far from unknown event in this area.
I have decided to change the Arduino Nano for a Mega as the Mega has internal memory I can use to store the results which looks easier to program than the SD card.
