Pedal Powered Electronic Waste Recycling Machine
“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.”
Human Powered Washer & Spin Dryer
The GiraDora is an interesting design for a foot powered washer and dryer that costs less than $40. More here:
“GiraDora is a blue bucket that conceals a spinning mechanism that washes clothes and then partially dries them. It’s operated by a foot pedal, while the user sits on the lid to stabilize the rapidly churning contents. Sitting alleviates lower-back pain associated with hand-washing clothes, and frees up the washer to pursue other tasks. It’s portable, so it can be placed nearby a water source, or even inside on a rainy day. It reduces health risks like joint problems, skin irritation, and mold inhalation. Most importantly, it uses far less water and cleans clothes faster than conventional hand-washing.”

Chinese Wheelbarrow Lives on in Angola, Africa
The ingenious Chinese wheelbarrow lives on in Angola, Africa. The contemporary design is similar to the Ancient Chinese vehicle, except it uses straight boards and a car tyre.
The machine and the men pushing it are both called “roboteiros”.

Pedal Powered Wool Carding Machine
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.
When Low-Tech Goes IKEA
What happens when two industrial design students from Sweden end up in Kenya creating a pedal powered machine for small-scale farmers who are often illiterate and speak more than 60 languages? You get a do-it-yourself design that seems to have come out of the IKEA factories – pictoral manuals included.
“Made in Kenya”, the bachelor project of Niklas Kull and Gabriella Rubin, is a textbook example of low-tech made accessible to everybody, regardless of their native tongue and language skills.
