A new paper shows the practicality of using Super Resolution Radial Fluctuation (SSRF) on an OpenFlexure Microscope. SSRF microscopy is a form of Super Resolution microscopy that relies on a post-processing method to generate a radiality map for each frame. This map is used to look for temporal correlations across frames to create an image […]

MicrobeMeter: A cheap Turbidimeter
MicrobeMeter is a compact turbidimeter designed to measure aerobic and anaerobic microbial growth dynamics. A formal description of the device is available on bioRxiv. You can buy one pre-assembled for $600, or you can assemble it yourself for $420. You can also download the design for non-commercial use for free if you register with humanetechnologies. […]
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 […]
A qPCR device for $300
A real-time polymerase chain reaction (real-time PCR), or quantitative polymerase chain reaction (qPCR), is a modification to normal PCR where one monitors the amplification of a targeted DNA molecule during the PCR. We’ve written before about our favorite cheap solutions for PCR, but check out this interesting paper on building your own quantitative-PCR (qPCR) machine written by Geoffrey Mulberry, […]
