November 11, 2017 | ProgressTH Orbital shakers are used to agitate substances in closed vessels such as jars, test tubes, and enclosed bioreactors.
Our design utilizes 608zz bearings (x6), a 12v stepper motor and driver, a potentiometer, and an Arduino Micro Pro to create variable, smooth, and reliable orbital motion control.
The files are all up on Thingiverse here: https://www.thingiverse.com/thing:2633507
Wiring diagrams and additional resources will be added soon. The platform itself was specifically designed to be removable via 3 bolts. This allows users to create custom holders to keep their vessels secure while in motion. The platform moves very quickly at full speed.
A quick video demo can be seen here:
Our projects are designed to give an example and a starting point for DIYbio and community labs a starting point for creating their own custom lab equipment.
