DIYbio Orbital Shaker V 2.0

cults3d

UPDATE: The rail system has been improved. If you've downloaded this model before July 4, 2018, make sure to switch out the railing system immediately. It uses M5 hex head bolts & nuts whereas the rest of the system employs M3 cross head bolts. A simple hot glue holds the hex head bolts in place within the knobs, just as it does with the hex nuts in the bars. You will need to print out (2) rails, (4) knobs, and (2) bars right away. INTRODUCTION This is version 2.0 of our DIYbio orbital shaker. We'll be adding in more info, videos, and assembly instructions very soon. All the electronics are still the same as the original version. So is all the Arduino code. The electronics diagram is included above in the images. The Arduino code will be provided below. Check out our prototype here for hints on assembly: https://www.thingiverse.com/thing:2633507 ...until we get some more documentation up for this version right now. The SketchUp file is included. It contains both the original prototype and the new version. It also has some designs not included in V 2.0 but you're free to use them or modify them as needed.
