I'm working on a machine that I need to help with my business. Essentially, I am looking for something that works similar to a VHS Rewinder / Fast Forwarder that has variable speed. See this video on Youtube for what I am trying to accomplish.
What I have been looking into is having two DC motors. Each engaged separately via a single DPDT toggle One rotates clockwise when engaged, the other counterclockwise when engaged. I think I have that part down, but I would like to have one speed controller that effects whichever motor is engaged at that time.
I was thinking that perhaps the speed controller would go between the power supply and the DPDT toggle, that way whichever motor is engaged would be affected by the controller. Not sure if this is correct or not.
I've love some help/advise on this. Maybe even a circuitry diagram if anyone feels so inclined. I'm new to this so trying to research this as I go. Thanks!
