A tiny Arduino laser cutter
The basis for Groover's axis was the two mini stepper motors from the DVD-RW drives. The motors drive the DVD head mechanism which either moved the laser cutting head, or the cutting table. My first starting point was to find a similar set of motors, and a reclaimed laser diode. However I wanted a slightly different design. Where Groover has the cutting table move on the Y Axis, I wanted a fixed cutting table.
Arduino Laser Engraver
I started this project because I wanted to make something that had mechanical, electrical and software components. After looking around on Instructables, I figured that an Arduino based laser engraver would be an interesting machine to make, and that the machine itself could make interesting things. Laser diodes have also advanced quite a lot in the last few years, allowing reasonably powerful DIY laser engravers to be made without the hassles of laser tubes. This machine can engrave wood and cut paper. I haven't tried other materials yet because there is no fume extraction capability - plastics generally create toxic gases when burnt.
Collective Action Newsletter
Tine De Moor (PhD; Ghent, Antwerp, and London) is professor "Institutions for Collective Action in Historical Perspective" at the department for social and economic history of Utrecht University. Through an interdisciplinary approach for the study of the long-term evolution of rural commons, De Moor has been able to revise the historical basis of the widely debated metaphor of the Tragedy of the Commons, as launched in 1968 by G. Hardin. Whereas from a modern-day perspective the flaws in Hardin’s theory have been well-documented, the historical deficiencies in his theory were hardly ever studied.

The design is simple and reliable ( u can see the video )
Why Paul Mason is wrong: you can't innovate away social oppression
Excerpted from a critique of the PostCapitalism thesis by Kate Aronoff: “Matt Taibbi wrote in 2010, banks are a “highly sophisticated engine for converting the useful, deployed wealth of society into the least useful, most wasteful and insoluble substance on Earth — pure profit for rich individuals.” Technology is just another hurdle they can ably jump over. Even against the information age’s more egalitarian impulses, tech remains firmly in the hands of the one percent — albeit a nerdier, tanner and more socially progressive one.

Best Essays of 2015 (1): Bernard Stiegler on the New Desires of Post-Capitalism
A new society could arise on the same technological base that is now still predominantly destroying the social bonds. The digital networks might be the prime catalysts in the transformation from today’s consumer society into what he calls a ‘society of contribution’. This is a strongly recommended interview to get to know the otherwise difficult writing of that most p2p of philosophers alive today, Bernard Stiegler, and whose ideas on the society of contribution, rather precisely match p2p theory, though at a much greater level of philosophical sophistication, for which the p2p/commons movement must be thankful to Stiegler. * Article: ‘THIS SYSTEM DOES NOT PRODUCE PLEASURE ANYMORE’.

Build Your Own Beautiful Flat-Pack Chair
I built this Eames-like chair without touching a single traditional woodworking tool. No, it's not because I'm some kind of Luddite. I just love the immediacy of rendering a chair with 3D modeling software and then cutting out the parts with a CNC machine. Everything snaps together like flat-pack furniture, but without the cheesy fasteners—just mechanically sound through tenons and lap joints. The manufacturing process takes 2 hours. To build this chair, you'll need a $25,000, full-size CNC router, such as a ShopBot.
Easy CNC conversion of a small mill
Why not a 3D printer? I think a lot more people have 3D printers than CNC mills and they're great tools. There's a bit of an overlap with a mill, but they both have their strengths and weaknesses. Comparing a mill to a printer we broadly have: Pros Cons
Jevons paradox
The Jevons paradox has been used to argue that energy conservation may be futile, as increased efficiency may increase fuel use. Nevertheless, increased efficiency can improve material living standards. Further, fuel use declines if increased efficiency is coupled with a green tax or other conservation policies that keep the cost of use the same (or higher).[3] As the Jevons paradox applies only to technological improvements that increase fuel efficiency, policies that impose conservation standards and increase costs do not display the paradox. History[edit]
Literary gold mine for CNC millers
From 1976 to 1983, Popular Science magazine, along with the American Plywood Association, ran an annual plywood panel project design contest for its readership. Often the winning projects were items of furniture, but that was not a requirement. A potter’s kick wheel and a folding plywood boat are notable exceptions.
