Re: [DIYbio] Stanford bioengineers develop a 20-cent, hand-powered centrifuge

The next thing they should do are tubes from clay, pipettes from bamboo straws and polymerase chain reaction using camp fire. Then someone could come up with a protocol for gene modification using only stuff you can find in the forest and claim that gene modification is organic. OpenPCR can then start selling organic free-range artisan PCR kits. :)

Inspired lolololol more like took the exact design. I love how this makes news and everyone is like "wow so creative!". The intermittent deceleration can shake up samples so I'm not sure how larger tubes will fare. Maybe a rotor with a fly wheel and a foot pedal might be more reasonable. If anyone has ever used the device, its a decent workout if the rotor is of reasonable size. Last thing I'd want is that thing spinning larger tubes in my face at 10krpm :P

Good progress, I hope they pay it forward. Its a slippery slope to cultural appropriation and in these times I'm sure someone already started to fan the hate flames. All in all it seems like a fun way to spin simple hematocrit vials or pcr tubes real quick.

This is probably as simple as a centrifuge can get. Can this design be improved? Can features be added?

"Inspired by a whirligig toy, Stanford bioengineers have developed an ultra-low-cost, human-powered blood centrifuge. With rotational speeds of up to 125,000 revolutions per minute, the device separates blood plasma from red cells in 1.5 minutes, no electricity required. A centrifuge is critical for detecting diseases such as malaria, African sleeping sickness, HIV and tuberculosis. This low-cost version will enable precise diagnosis and treatment in the poor, off-the-grid regions where these diseases are most prevalent. For more info: http://stanford.io/2j2MDjM
