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. The site has lots of formulas for the urban homsteader even if you never have to perform a Sallen-Key Butterworth Low Pass Filter equation (except, perhaps, for recreational reasons). Thanks to Bruce Nolte, N1BN for the...

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...

Help us With a Fodder System for our Hens

...e need something much smaller! I feel somewhat guilty about having our five hens in a confined coop/run. Ideally they’d be grazing on green pasture all day. But our abundant urban predators, lack of space and dry climate make the vision of hens clucking on verdant fields a challenge. I’m thinking of building a DIY fodder system but I’m a bit confused by the instructions I’ve seen floating about the interwebs. Which is wher...

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....

Apartment Parking Lot Gardening in East Hollywood

...ucky neighbors in my apartment building, not to mention bragging rights and a sense of eco-green accomplishment. These boxes can be easily made and you can even have all the pieces cut at your local Home Depot or lumber yard and you just nail or screw them together. I would recommend that you use 1 x 8 x 6 ft. fence boards instead of the 1 x 6, though, and fill the soil about an inch below the boards so when watering the water doesn’t spill...

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...

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...
