DIYbio Orbital Shaker V 2.0

thingiverse

UPDATE: The rail system has been updated with significant improvements. If you've downloaded this model before July 4, 2018, make sure to replace the original railing system. It utilizes M5 hex head bolts and nuts, whereas the rest of the system employs M3 cross-head bolts. A small amount of hot glue is used to secure the hex head bolts in place within the knobs as well as the hex nuts in the bars. To assemble this DIYbio orbital shaker, you will need to print out two rails, four knobs, and two bars. INTRODUCTION This is version 2.0 of our DIYbio orbital shaker project. We're adding more information, videos, and assembly instructions in the near future. The electronics remain the same as the original version, along with all the Arduino code. The electronics diagram can be found above in the images, while the Arduino code will be provided below. For hints on assembly, check out our prototype here: https://www.thingiverse.com/thing:2633507 Until we get more documentation up for this version, you're on your own. The SketchUp file is included, containing both the original prototype and the new version. It also features some designs not included in V 2.0, but feel free to use or modify them as needed.
