Energy & Sustainability

If you’re a maker just starting out your journey in sustainability, it can be overwhelming to figure out how to get started. From understanding the types of materials to utilize, learning what steps will help reduce waste and emissions, and finding inspiring new ways to explore creativity that don’t have a negative environmental impact. The good news is there are plenty of resources available for DIYers looking for ways to make their projects more sustainable – from simple switches you can make today, big-picture ideas for longterm change, or exciting new ways makers are helping push sustainability into the future. In these blog posts we’ll look at tips tricks and ideas specifically tailored towards diyers and makers on the road to creating projects with greater eco consciousness so that not only will you create something beautiful but also respect its impact on our planet!

Homemade Play Kitchen

Erin Woodward, who runs the blog Sutton Grace, has created a fabulous play kitchen for her daughter out of an old entertainment center. You know, the kind you see for sale at almost every garage sale you’ve ever been to in the burbs. Although the one she used in her reuse project was a bit […]

Visual structure of a zen rock garden

Just ran across this fascinating little paper published in Nature back in 2002 by Gert J. Van Tonder, Michael J. Lyons, and Yoshimichi Ejima. In it, the authors apply a simple shape analysis to the layout of the 15 boulders in Japan’s most famous karesansui (or “Zen garden,” as they are often called in the West) at the Ryōan-ji temple in Kyoto. The technique they use is called “medial axis transformation,” which, by my understanding, basically means that they took the Voronoi diagram of the boulders in the garden as viewed from above. The paper’s authors explain their method with an elegant analogy:

Portable automated greenhouse

Portable automated greenhouse

My project is a portable greenhouse / seed starter that has high tech features and collapses for easy storage. Since a standard greenhouse can overheat if it is closed up or get too cold if it is opened up, mine includes an automatic vent that controls to a user selectable temperature. The user first selects a temperature between 60 and 95 degrees Fahrenheit, by 5 degree increments. Then the greenhouse’s built in sensors and microcontroller automatically adjust how much the vent is opened or closed to help maintain that temperature. And because of its ultra low power design the whole thing can run 24/7 for about a month on just four penlight (AA) batteries!
