How To Calculate Anything

...e think this is pretty cool.) Need to calculate Ohm’s law? Convert women’s clothing sizes? Calculate the area of a circle? Figure out whether its better to buy or rent a home? It’s all at www.calculatoredge.com.

As Above, So Below

...eople how to make their own low-cost telescopes. As a monk, Dobson could not afford expensive materials. He kept the design inexpensive by using a simple mount and cheap materials: wood and cardboard. My Dobsonian was made by the now defunct Coulter Optical Company out of particle board and a cardboard concrete form. Its large 13.1 inch mirror makes it perfect for looking at nebulas, galaxies and star clusters even in light polluted urban areas....

This is where trial and error comes in. Sometimes the only way to find out if what will grow is to plant stuff and see what takes off. 2. Soil compaction This is a big problem in urban areas and our yard is no exception. The parkway, which gets a lot of foot traffic,...

Apartment Parking Lot Gardening in East Hollywood

...#8217;s post proves that you can start a garden even if you don’t own a house and how an otherwise useless urban space can be put to good use.

So based on the “Square Foot Gardening Book by Mel Bartholomew I bui...

Root Simple’s New CritterCam

...7;s a digital still and video camera with a infrared flash and a motion detector. If something moves in front of the camera a picture or video is taken. It also stamps the time and records temperature and moon phase. [See update at the end of this post--this is probably the wrong camera for the application I intend. Thanks Max!] My plan is to use it for some urban, backyard citizen science. Specifically I want to figure out a few things: What ma...

The High Cost of Golf

...t. Instictively, we ducked thinking that someone was shooting at us. Though my heart was racing, I soon realized the culprit: a errent golf ball sent hurdling over the fence by some anonymous, impossible to trace Tiger Woods wannabe. We circled back to the club house to file a report with the manager of the course and begin the long tedious process of settling the insurance claims. So what does this have to do with urban homesteading? A lot. It...

Journal of the New Alchemists

...d the Journal of the New Alchemists deep in the closed stacks of the Los Angeles Central Library. As revealed by their journal, what distinguishes the New Alchemists from other efforts of the time is the Todd’s science background. The Journal has a refreshing research-based approach to its subject matter. The period I reviewed (their last decade of publication) covers mostly their agricultural experiments, but occasionally dips into urban p...

A Year after The Age of Limits: 5 Responses to the End Times

...earning to be free of laws and civil constraints, to reduce our overly complex society into a simple survival of the fittest paradigm, where, at last, we perhaps can find the fulfillment we lack.  Mind, personal fulfillment is the positive spin on this fantasy–the negative one would point out that there’s some pretty fishy stuff involved here in regard to race and class, urban vs. rural, and suppressed desires to blow out our neighbor...
