Orbital Shaker DIYBio

This is an orbital shaker with a modular design that employs simple electronics which require minimal soldering skills to assemble. The removable tray has an array of M5 holes into which special mounts can be screwed. Mounts for 125ml and 250ml Erlenmeyer flasks, as well as that for a a 125ml tissue culture flask are included.

I used a 100 RPM motor, but other speeds are available if you need something a little faster. The motor controller allows the speed to be continuously varied as needed.

Required materials:

608 bearings (http://a.co/d/4amTGEh)
