3D Printed DIYbio Opensource Centrifuge

November 21, 2017 | ProgressTH Our 3D printed DIYbio centrifuge v 2.0 is operational. With version 1, we used a brushless motor used on drones which required an electronic speed controller and an Arduino microcontroller just to get it to spin. This version uses a simple 12V DC motor controlled by simply flipping a rocker switch.

A microswitch located near the cover cuts the power when the cover opens, and returns power to the motor when it is closed. It is a common safety feature found on many laboratory micro centrifuges.

Because it is much simpler and because there is a lot of extra space in the housing, a lot of expanded functions can be added later by users. While this version does not require a microcontroller of any king, there is plenty of space to add one (for timers or other functions).
