i wanted to play with microcontroller for drip irrigation, pumps, solar powered etc<p>Simpler, natural solution exists for plant+fert+pesticide:
wet field: a combo of rice+azolla+sheep+duck+fish
dry field: a combo of rice+white clover<p>Similarly, i wanted to play with microcontrolled fish-keeping, pump, filter, aerator, heater, fertilizer ... fancy stuff<p>Simpler, no-tech natural solution again exists:
just use soil+aqua plant+sunlight<p>Really, nature amazes me to no end, to the point that i hate my engineering knowledge ... i truly concern that my creation will be inferior to nature<p>For reference, the natural books:
one straw revolution: masanobu fukuoka
the power of duck: takao furuno
