Hey guys in in the middle of building another bator. Im using an old evian water cooler. Im still fuzzy on the motor to turn the trays. Im wanting to use a motor I got off of a pair of xmas yard decoration. I think it was two dolphins dancing .. anyways I need some ideas on how to slow down the motor? Maybe a big gear drive??? And another question can I wire 2 computer fans to run off one 12v powers supply? maybe both series or paralell?
