We're building a DIYbio lab, including custom-building the equipment.
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.
October 26, 2017 | ProgressTH Our 3D printed DIYbio centrifuge v 2.0 is operational. The rotor still needs to be balanced. On version one, we used a brushless motor used on drones and the spindle was very easy to mount the centrifuge rotor onto. Our 12V DC motor has proven to be a bit more difficult.
Despite that, it does work. The microswitch cuts the power to the motor when the cover is opened, a feature v 1.0 didn't have. 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 by users.

October 21, 2017 | ProgressTH This new version of our original F.Lab centrifuge we are working on will use a 12v DC motor, and a basic rocker switch to make the simplest and easiest centrifuge design possible. However, the design includes provisions to add in a microswitch to automatically turn off the motor when the cover is open, and a microcontroller (Arduino Nano) for timing functions.
Additionally, the actual centrifuge rotor has been slightly modified in SketchUp to include more sides and thus produce a smoother circumference. This may help further stabilize the rotor while in motion.
While the brushless 1806/2400 drone motor was strong and fast enough, it was expensive, a bit more difficult to find for those who don't order online, and interfacing with the ESC via an Arduino is not easy for many beginners who might otherwise want to tackle the project.
The thought process behind this new version is to make a platform simple enough, and with enough options for modification and improvement so that more people build the design.
From the beginning, we plan on offering two versions that will be available on Thingiverse, one with a solid fully 3D printed cover, and one that integrates acrylic so the rotor can be viewed when in motion. This lets makers who have access and experience working with acrylic have the option for a window, while the solid cover is easier for anyone with a 3D printer to make regardless of their resources and background.
We were pleased to see others make our original centrifuge including Make Magazine. Japan-based maker Shingo Hisakawa has already improved upon the original design, offering his improvements here for free on GitHub. We hope this new version attracts even more enthusiasts to try out opensource DIYbio hardware.
May 10, 2016 | ProgressTH We had to start on Hackaday.io all over again because we couldn't log into our old account. No worries, we've decided to consolidate all our DIYbio projects into one log since they really are all inter-related anyway.
We've just finished up 3D printing our DIYbio electrophoresis system. We've been developing a protocol to use to test it. It will require the use of our previously completed systems, the centrifuge and magnetic stirrer. If all goes according to plan, it will go up on Thingiverse and Instructables. Until then, follow along here for updates.
