nhi @Hail_Harry and all others eager to build cool lab-gear from scraps and pieces, dumpster-divers and fabbers.
we have kinda documented a whole set of simple lab gear, such as shakers, mixers, spin-coaters, wigglers, made from all kinda left-over parts from computers and other recycled hardware. an overview is here:
many times we offered this as workshops for dissassembly and building lab tools. such as this one:;
talking about centrifuges, we experimented with various motors, i see above a computer fan. i guess we can reach higher speeds using harddiscs and a motordriver (which you can buy cheap from ali).
but then… a centrifuge ist more than a fast motor and a eppi-holder… it’s primarily a solid big lid!!! to protect you from stuff flying around (or into your brains).
the all time classic DIY microscope of course is also always a great start, especially if you focus on using locally available construction material and prototyping a decent stage for sample and focusing. webcams… usually not too easy to find in a trash, but relatively affordable on various online stores, approx 3-4USD.
I started a topic abour discussing / developing specific GOSH workshop modules, to share partially the skill to build a specific equipment, but more important some fundamental understanding of the “open” source approach, hacking methods, interdisciplinary colloaboration, fast-prototyping, creativity and critical thinking. not so much response yet…
