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....

A New Reality

...yle as something impossible to accomplish. The underlying message? Stay on that couch, don’t try to change the world, just buy the crap our advertisers sell. These type of realty shows are also a rigged version of the prisoner’s dilemma in which the cooperative option (what most people tend to choose in stressful situations) is not allowed. We need to tell a different story. Bloggers in the urban homesteading movement can join togethe...

Gardening Mistakes: Six Ways We’ve Killed Plants

...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, is very compacted. Very few plants do well with compacted soil, including natives. The best way to break up compacted soil is with a broadfork, a spendy item. We use a garden fork instead. 3. Soil fertility When it comes to growing vegetables, in p...

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...

Keep Those Bikes Locked, Even in the Garage!

It goes without saying that you must lock your bike when out and about. Leave it unlocked for one second in most urban areas and you can bet it will be gone when you return. In San Fransisco, for instance, bike theft outstripped iPhone theft 3:1. But there’s another kind of bike theft that a lot of folks don’t think about–theft from your home or apartment. Yes, even at home base your bike needs to be locked...

Help us With a Fodder System for our Hens

...8217;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 where you come in. Have you built a fodder system? Do you know any good instructions? How big should it be for five hens? O...
