Since an Arduino will be inside the rainwater tank, I will need some electricity
there as well. I could exclude using batteries since an Arduino isn’t exactly low
power and I needed to power some sensors as well.
I finally moved from an apartment to a house. That also meant, I suddenly had a garden
to take care of. The first year was spend with cleaning up the ground. There was plenty
of construction material leftovers from the construction company. And a lot of weed.
Every evening I cleaned up a small area of the ground with a sieve sifting out stones
and weeds up to 30 cm deep. I ended up with at least 600 kilo’s of stones and too many
bags of weeds to count.
