show all recycling/reuse new to old

compost temperature

Knowing the temperature deep in my compost pile gives me an idea of how well decomposition is going. As shown by a thermocouple 24 inches into the pile, roughly in the center, temperature is almost 127F!

weatherproof rotation switches from recycled thermostats

A good source for rotational switches can be had in old thermostats which contain a mercury switch or two.

new use for old television antenna towers

We have a large west facing deck which can become unbearably hot on a summer afternoon. I used old tv antenna towers to create horizontal struts on which to hang landscape fabric and created a very effective sunscreen that did not catch the wind.

new uses for old tv towers 2

Old television tower sections are low- or no- cost structural components that can be re-used for horizontal spans like this small footbridge that was made over a single weekend. The boards I used for the top and sides are salvaged 2x4's that otherwise would have been scrap.

useful springs from old printers

Everyone who builds things needs to find sources of parts. A discarded printer is a gold mine of small springs for your projects.

sources for gear motors

I've had an interesting ongoing email conversation with a person in Mexico who bought my plans and was very interested in building a solar parabolic heating system for himself. He had been having trouble getting the specific gear motor that I recommend in the plans. In any DIY (Do It Yourself) project sometimes it is necessary to improvise.

when used is even better than new

Our economy depends on our collective desire to own more, the newer the better. Whatever the sponsors tell us, we want. But our behavior creates enormous problems for society in terms of credit and waste.
