GeoPathfinder Many people currently cook in a microwave oven. It’s called “micro” because the high-frequency radio energy used to jiggle the food’s water molecules has a very short wavelength. We call our stove the macrowave because, even though it utilizes radiated infrared energy (heat) which has a much higher frequency and even shorter wavelength, the… Read more »

This book describes a way of making compost, i.e. humus, which is simply, labour saving (no turning) and quick, both in ripening the compost and in getting results in the soil. It is adaptible to all conditions and to every size and type of garden, allotment or farm, the process being based on nature’s own methods.
I have the opportunity to add “smart” technology to my house as I’m building. I’m considering using either, or both, arduino boards & Raspberry Pi computers as the main processors to which I’ll attach various sensors and switches.
