As the title says, what do you do with un-used taps on a transformer. I have another thread going in the projects forum about making a 500v circuit for a Geiger Counter. I was able to get 500v using a transformer from a disposable camera.
My question now is what to do with the un-used center tap. I was originally not going to do anything with it since it seems to be working fine. I did however notice that in the disposable camera circuit board the center tap was connected to batt + with a 1.5k resistor.
I also noticed another Geiger Counter schematic where the center tap of the transformer went directly to batt + with no resistor at all. Here is a copy of that schematic... http://uzzors2k.4hv.org/index.php?page=geigercounter
Is there a problem with having a floating transformer tap? I can't think of a reason it would need to be connected to anything. But then again I am new at this stuff.
