Mechanical 3D Printer
April 22, 2015 by Filed Under: 3D printers, Craftsmanship, DIY, Random
“3D printing allows me to create products more swiftly and more efficiently than ever. But these products don’t feel mine. They are merely a product of this new technology. I love technology but how can I reclaim ownership of my work? Perhaps by building the machine that produces the work. Perhaps by physically powering the machine, which I built, that produces the work.”
Instead of building a traditional 3D printer, Daniël de Bruin decided to harken back to a past when pantographs and mills ruled the shop floor by making a device which doesn’t require software or electricity to work its magic. His 3D printer is driven by a 7.5 pound weight. “The weight allows me to be connected with the process because there’s no external force involved like electricity; it’s still me that’s making the print,” says de Bruin. “By physically building and powering the machine, the products that come out of it are the result of all the energy that has gone into it.”
For those who complain about the speed of FDM 3D printers, de Bruin says his machine is actually faster. It all comes down to a nozzle diameter of approximately 2mm – rather than the 0.35mm – 0.4mm which is the standard for most 3D printers. While there may be a slight loss in quality with his process, he says his old-school machine can print objects using clay material, pasta, starch bio plastics, and pretty much any material that can fit through the extrusion nozzle, which doesn’t require heat.

Can We Reboot Civilisation Without Fossil Fuels?
April 22, 2015 by Filed Under: Energy
“Would a society starting over on a planet stripped of its fossil fuel deposits have the chance to progress through its own Industrial Revolution? Or to phrase it another way, what might have happened if, for whatever reason, the Earth had never acquired its extensive underground deposits of coal and oil in the first place? Would our progress necessarily have halted in the 18th century, in a pre-industrial state?”

Let’s Grow Some Furniture: Botanical Manufacturing
April 22, 2015 by Filed Under: Random, Trees, Wood, Woodworking
“An ingenious British designer has come up with the ultimate environmentally-friendly way to create stunning household furniture – by letting Mother Nature do all the hard work. Gavin Munro grows young trees into specially-designed plastic moulds, pruning and guiding the branches into shape before grafting them together to form ultra-tough joints. Using this method he’s already created several prototype pieces and has a field in Derbyshire where he’s currently tending a crop of 400 tables, chairs and lampshades which he hopes to harvest next year.”
“You start by training and pruning young tree branches as they grow over specially made formers. At certain points we then graft them together so that the object grows in to one solid piece – I’m interested in the way this is like a kind of organic 3D printing that uses air, soil and sunshine as its source material. After it’s grown into the shape we want, we continue to care and nurture the tree as it thickens and matures before harvesting it in the Winter and then letting it season and dry.”
“Each of the pieces have grown from one tree, planted specifically for that reason, its limbs guided in an exact shape and later grafted together to produce the unique pieces of furniture, which he hopes are the pioneers of a new method of sustainable, efficient and ecologically aware production.”

Turning the Soil with a Bicycle Handlebar
April 18, 2015 by Filed Under: Farming, Hand tools
The agricultural tool shown in this video is pure genius. However, as some readers on our Facebook-page have noted, turning the soil disrupts soil organisms and brings more weeds. Another human-powered tool, the broadfork, loosens the soil without turning it. Thanks to Jean Armstrong Nick and Austin Liu.
The Case For Dangerous Roads and Low-tech Cars
April 18, 2015 by Filed Under: Cars, Low-tech cars, Random
“The design of automobiles has tended toward insulation, offering an ever less involving driving experience. The animating ideal seems to be that the driver should be a disembodied observer, moving through a world of objects that present themselves as though on a screen. We have throttle by wire, brake by wire, and electrical assist (versus hydraulic assist) brakes, as well as traction control and anti-lock brakes that modulate our driving inputs for us. What all this idiot-proofing and abstraction amounts to is a genuine poverty of information reaching the driver.”
“What’s more, the information that does get through is presented in a highly mediated way, conveyed by potentiometers and silky smooth servos rather than by the seat of your pants. It is therefore highly discreet, and does not reflect fuzzy, subtle variations. Nor is it sensitive to changes that haven’t been anticipated and coded for ahead of time, for example the vibration that might arise from a brake caliper bracket that has come loose or cracked. Perhaps most troubling, the electronic mode of presentation means that information about the state of the car and of the road is competing with information from other electronic devices that may be a lot more interesting.”
