Technology for Luddites
The Culticycle is a pedal powered tractor that can cultivate, seed, spray, or pull gear for most low horsepower tasks. We talked about the first prototype almost two years ago. A new version has now been released, built around a modular tractor frame. Tim Cooke explains us how it’s built and how it works: [Read more…]
“A highly unusual bicycle, designed to help recycle unwanted woollen clothes, unravels any clothing item back into its pre-knitted form. It has been selected as one of the best student design projects of 2012 by the British National Centre for Craft and Design.”
“The un-knitting machine is based on pedal power and built around an old bicycle frame. The un-knitter sits on a chair pedalling and wool passes through steam coming out of a kettle before being collected on a spindle. The machine was designed by Imogen Hedges, a student at Kingston University.” Read more. Via Treehugger.

“The bicyclean is a safe, affordable, and efficient alternative for
harvesting electronic waste in developing regions. The bicyclean is a modified bicycle, where a processing chamber replaces the rear wheel and an external steel frame supports the rear hub. Processing of the circuit boards occurs within the sealed chamber and the particles are removed in a covered tray. A feed tube presses circuit board pieces into a large grinding wheel and become pulverized.”
“The particles pass a magnet that extracts ferrous metal particles. The particles then flow over a small eddy current rotor, which is positioned underneath the grinding wheel and powered by a 3:1 gear ratio with the bicycle chain. The changing magnetic fields of the eddy current rotor repulse conducting metal, but have no effect on non-metals; the metal particles are projected horizontally while the nonmetals fall vertically, separating particles in the bottom collection tray. The bicyclean requires a single operator.”
The Cyclocarder by Fibershed-contributor Katharina Jolda is a wonderful update to the article on pedal powered machines. The Cyclocarder can turn your backyard, community center, or farm into a human powered wool processing station.
“Originally designed to serve the load carrying requirements of the Tri-Sled factory, the FlatBed Truck is a high-bulk load carrier. We use one of these for getting around our local industrial estate, transporting frames and fairings to our powder-coating and painting contractors, or picking up steel and other oversized materials.”
“The FlatBed Truck is far more convenient than carting large items to and from a car or van. With this maneuverable vehicle, you can simple roll straight in and out of your business or factory. It even serves as a handy rolling work bench for working outside on sunny days.”
“The FlatBed Truck is also incredibly easy to store. Just flip it up on its end when not in use, and use the rear rolling wheels to move it against a wall or into a small space. The rolling wheels also serve as a back bump stop.” Trisled FlatBed Truck.
