Latest Circuit Update
Well I made the changes as I understood them, but I am not sure if the results are as would be expected. I am trying to understand the issues regarding Gain and how this affects the result, but I am doing more research to see if I can figure it out.
I guess my concerns now are as follows:
1. The readings in the center of the Bridge indicated only 12.9V rather than something much closer to the 21.8V from the Constant Current Source, at the top right of the diagram. It also appears to show the ma as a negative on the side that is 12.9V…
2. I am not sure that my method of switching the sides is correct, since one of the results is based on the Timer output being OFF. Will the power be provided to each side be based off the voltage applied to the actual IC?
I have 6 NPN mps2222ARLRAG's from BenTronics and 2 NPN NTE123AP's I bought from Fry's. I need to check to see if any of these will work or I will need to buy something different when I get the PNP's (I will actually be near a Fry's Saturday and Sunday, which I hope will have more than RadioShack and BenTronics ever carry...)
I really appreciate all the help I have received and hope that my questions do not frustrate either of you, as I am trying to research as much as I can…
My daughter has a Softball Tournament Saturday and Sunday, so I will not have my laptop with me until later in the day…
Although you may get tired of hearing it, but I again can not thank both of you enough for the time and efforts that you have already provided. Thank you.
BHinote.
