The Wally120 OpenKnit Machine
Inspired by the work of Sabetta Matsumoto and Julianna Abel, we have been looking at programmable automatic knitting machines on the cheap. Several scientists research the creation of unique metamaterials by programming them with lattices of slip-knots, a process colloquially known as knitting. A low-end industrial programmable knitting machine, from Shima Seiki costs between $90,000 […]
Precision for $100: The OpenFlexure Microscope
The OpenFlexure Microscope is an open-source 3D-printed microscope, based off a precise flexure translation stage. If you’re making them in bulk and without the high-res parts, the per-unit price is probably below $100. If you’re just putting together one, the price will probably come to more like $200 and you’ll find yourself with a lot […]
$2 microfluidic pumps made of latex balloons and stockings
Generally, microfluidic systems require an external pump system to operate. Self-sufficient microfluidic systems are microfluidic systems that have all the components they need on the microfluidic device itself. This is a key concept in lab on a chip designs (the devices from whence this website puns its name). A paper from Peter Thurgood, Sergio Suarez, […]
