I woke up yesterday to the normal sounds and sights of kookaburras and magpies. Though this time they had a brand new perch to spot worms from..my weather station
One kookaburra was even cheeky enough to land on the wind speed buckets and spin round and round
all I could do is laugh as the birds played musical chairs with my weather station. Then I spotted one magpie using the rain gauge as a toilet was the final straw.
Several 1mm thick SS tig welding filler wire rods later along with some twisting cutting and manipulation I think I have it sorted. The trick was to try and create a spiky deterrent that would have little to no impact on the rain gauge and do the same with the wind cups. The birds gave it a miss this morning so must have worked.
I also added some weight to the wind direction vane. I was finding at times with very mild wind speed combined with disturbed air at the location it was just to sensitive. I was getting way to erratic wind direction plots. The weight has helped a lot to tighten the graph up a bit. Though I still just have to expect less than perfect wind direction graphs in the disturbed air location.
Having to run a windows pc running 24/7 was a consideration being offgrid. My little mini pc (that's getting a little long in the tooth at 9 years old) was very efficient at the time (20 - 30W) but by today's standards it's terrible.
I had a 7" windows 10 tablet that I was given as it had a bad internal lithium battery and would shut down (even when externally powered) after a few mins. I removed the internal battery for safety and soldered a USB cord to the BMS terminals.Then drilled a small hole in the back cover to run the USB cord out and I can now power it from a tiny 5v 1A USB wall plug (phone charger)
The amazing thing is when this windows 10 pc is running the logging software and uploading it over WiFi it consumes 2.8W with the screen on and 1.5W when the screen is turned off. We really are lucky now days this little device most likely has more power than a desk top pc from not that long ago and uses less power than bedside alarm clock. You can pick this kind of thing up new for about $50 at times or even less 2nd hand.
Looks like it will hit around 30C today so things are starting to warm up. Some rain tomorrow and the plants and the weeds
are loving this combination.
