#315 mins of human labor per test doesn't sound cheap but I guess you can get the patient to do it themselves.
A bit curious, why is a cheap centrifuge hard to build? It seems like a pretty simple device and motors are pretty cheap.

Motors need power, not having (much) power at hand is often one of the first problems helpers in such situation have, so something which doesn't need power is a huge boon.

In the environments this would be used Labor is cheaper than and probably more available than electric power. This could also be built on site rather than trucked in, all you need is the knowledge of how to build it. In some instances, this kind of tool may be the only way to meaningfully accomplish testing.

It's not: https://diybio.org/2012/06/11/dremelfuge-classic/
But presumably this could be for regions in which even those materials are difficult to obtain.

Exactly. One of the reasons the recent ebola epidemic hit where it did is because there are still many areas where clean water and bleach (which would have prevented much of the outbreak) are difficult to obtain.

I can't remember using it to centrifuge blood samples, but maybe your childhood was different from mine.

While they're not that hard to build, the lab ones tend to be very heavy and not able to survive being carried around and dropped. The centrifuge they describe can be easily transported, is durable, and easy to fix. It's a great idea to be able to provide field medics with a tool like this in difficult environments where a lab grade device would be impractical.
