From “How to make everything ourselves: Open modular hardware” by Kris de Decker:
Reverting to traditional handicrafts is one way to sabotage the throwaway society. In this article, we discuss another possibility: the design of modular consumer products, whose parts and components could be re-used for the design of other products.
Initiatives like OpenStructures, Grid Beam, and Contraptor combine the modularity of systems like LEGO, Meccano and Erector with the collaborative power of digital success stories like Wikipedia, Linux or WordPress. An economy based on the concept of re-use would not only bring important advantages in terms of sustainability, but would also save consumers money, speed up innovation, and take manufacturing out of the hands of multinationals. A modular system unites the advantages of standardisation (as parts can be produced cheaply in large amounts) with the advantages of customisation (since a large diversity of unique objects can be made with relatively few parts). Modularity can be found to a greater or lesser extent in many products (like bicycles and computers) and systems (like trains and logistics), but the best examples of modular systems are toys: LEGO, Meccano, and Erector (which is now the brand name of Meccano in the US).
In spite of the similarities, there is one fundamental difference between modular construction systems such as OpenStructures, Grid Beam and Contraptor, and modular toys such as LEGO, Meccano and Erector. The first group consists of “open” modular systems, where everyone is free to design and produce parts, while the second consists of “closed” modular systems, where all parts are designed and produced by one manufacturer. Closed modular systems produce uniform parts. For instance, all LEGO building blocks are made of plastic. LEGO does not produce building blocks made of wood, aluminium, glass or ceramics. There is a limited range of colours. And because LEGO is a closed system, nobody else is allowed to produce LEGO pieces.
An open modular system has many advantages over a closed modular system. Since anyone can design parts in an open system, it generates a much larger diversity of parts: they can be made in different colours and materials, and none of the producers can set a fixed price for all consumers. And because many designers constantly review, adapt and improve each others’ work, innovation is accelerated. All open software systems described above are arguably better than their closed counterparts, and some of them have become more successful. A closed modular system only has one advantage: the one who holds the copyright makes a lot of money.
Open modular construction does not mean that everyone should make their own consumer products. An object like a coffee maker or a workbench could be obtained in at least three ways. Firstly, the consumer can download the digital design and then assemble the object with parts that he or she buys, re-uses, or makes using a 3D-printer or laser cutter, whether at home or at a fab lab or tech shop. It can also happen in a more low-tech fashion, as is the case with Grid Beam: the consumer buys wood or metal beams, and drills the holes himself.
A second option is that a company buys the license of the design (if it is not free) and converts it into a building kit, comparable to a kit from LEGO, Meccano or Erector. In this case, the consumer would not have to search for the parts himself, but he still assembles the product himself, just like he would assemble a piece of furniture by IKEA. Similarly, a company could offer a more general building kit, which can be used to make whatever one would like, similar to a box of basic LEGO bricks. Bit Beam, Contraptor, Open Beam, Maker Beam and, recently, Grid Beam offer one or both of these options.
The third possibility is that a manufacturer places the object on the market as a finished, assembled product. The coffee maker or the workbench would then be sold and bought just as any other product today, but it can be disassembled after use, and its parts can be re-used for other objects.

From “FarmHack: Collaboratively Retooling Agriculture” by Benjamin Brownell:
FarmHack is a network for sharing open source know-how amongst the distributed fringe of DIY agricultural tech aficionados and innovators. In the same vein as Appropedia or Open Source Ecology, a collaborative digital knowledge-base facilitates the harvest of crowd wisdom to address challenges and inefficiencies in modern ecological (and economical) farm operation. It is a project of Young Farmers Coalition and somewhat angled to the exuberant and tech-savvy eco-preneurial demographic, but inclusive and supportive of all open earthy inhabitants.
A primary focus of the organization is toward intensive development meet-ups, teach-ins, and hackathons, in person, on the farm. Just after landing at my new rural summer farm home and hack-factory in Vermont, I learned of one such get-together nearby on Lake Champlain. It appealed as a chance to meet peers, learn about the local Intervale organic agricultural enterprise collective, and practice some “agile” collaborative protocols in fresh context.
We were first treated to a tour of the Intervale Center, and the predominantly “hacked” implements and equipment of its Farmers’ Cooperative, such as automated greenhouses, root vegetable washer (designed in conjunction with University of Vermont engineering students), salad greens dryer (Amana brand washing machine uncased and set to spin), four-barrelled flame-throwing weed exterminator, and electric tractor-to-be. Use of these is on a per-hour honor system basis, with a proportional pooled fund (plus lots of good-natured volunteer effort) to cover maintenance, repairs, and new purchase. It’s effective, productive, and proliferating (link is an “idea worth sharing” pdf pamphlet on farm equipment co-ops from University of Sasketchewan Center for the Study of Cooperatives).
Rural areas–so many in stark economic decline today–are in fact a wealth of raw materials, practical skill, and entrained devotion towards creative repurposing and sustainable initiative. Some of the best comfort and satisfaction about life on and with a piece of land, is that there is always plenty to “do;” to explore, to evaluate and improve upon, to hack away at in a mechanical or strategic manner–with room for creativity and eclectic flair–leading directly to concrete (frequently delicious and/or nutritious) result.
Commercial crop production and domestic animal management is intensely context-sensitive and dynamic vocation. It’s frequently demeaning and discouraging. It’s relatively crap pay. And, it is occasionally a paramount satisfaction returned for gritty labors in the public interest that are literally life-giving. Sustainable food systems are the long-range engine and “money supply” of our civil society. Open sourcing the know-how and effective story lines of successful ventures within this realm will invite citizens back into the processes and rewards of collaborative solving for abundance, ecology, community, and culture.
