A low cost microfabrication toolbox

If you are interested in working with microfluidics and are having difficulty getting started, check out a paper by Jérôme Charmet, Rui Rodrigues, Ender Yildirim, Pavan Challa, Benjamin Roberts, Robert Dallmann, and Yudan Whulanza. The paper describes cheap solutions to several chamber fabrication techniques including photolithography, micromilling, 3D printing, xurography (knife cutting) and screen-printing. The […]

OpenRAMAN, a $3000 DIY Raman spectrometer

Raman spectroscopy is a technique in which light from a laser interacts with a sample to shift the laser wavelength. Recording the shifts with a spectrometer gives information about the sample. We’ve covered general cheap spectroscopy more than once here. OpenRAMAN is a project to assemble a Raman spectroscopy setup using about $3000 in (mostly […]
