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 […]

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, […]

DIY Fluorescence Smartphone Microscopy

We’ve covered several portable microscopy setups before, including Foldscope, wooden scope, and our favorite these little UV magnifiers. We like the latter so much because it is capable of both white light, and UV light, and we found we were capable of doing a little bit of fluorescence microscopy on it. That’s where a 2017 […]
