Fixing a power hub for micromanipulators

   There was overnight leakage of the cooling water for the chilling stage under dissection microscope in one of our student's electrophysiology rig. The dripped water soaked the the entire power hub for micromanipulators under the anti-vibration table. It stopped working, of course. It is Siskiyou MC1000e. It would cost $$$ if you buy a new one.

   By checking around with an electrical tester, I found a disconnected path on the printed circuit board. I had to create a new path with a hook-up wire (red arrow).



















    There was another bad news. One of the pins in the male D-SUB connector was also broken. I don't know how it could happen but it was one of the critical one that feeds current to the manipulator. I created a fake pin from a piece of hook-up wire and attached into the connector. It worked well.

    Now the manipulator is moving fine.
    You know, I can be the author of "Zen and the art of electrophyiology rig maintenance" some day.
