Introducing a 2D (X-Y) Joystick controlled stage I designed and built for Optical Tweezers, but could be used with any inverted microscope. This was a low budget stage system composed of parts from different vendors.

In one of the DNA-sequencing experiments based on change in pH difference due to release of proton per nuceotide added to DNA. There was considerable pH change in pH due to various factors out of which one was due to the pH-sensor position inside the well; sensor kept stable vs sensor moving in the well in circular motion gives different result. So the pH rocker is designed to simulate the hand motion for the sensor and stabilize the results. http://openwetware.org/wiki/User:Pranav_Rathi/Notebook/OT/2012/05/21/pH-rocker_for_DNA-sequencing_experiments
