what is patented what is not. this circuit was my own idea

sorry about the language, sometimes I forget that not all posters are well versed in englis. "Patent solution" is an expression used for solutions that are not thought through.

The fact that after Charles were criticised for publishling a "solution" without knowing what type of battery Ayman were going to use you published a "solution" again knowing what type of battery made that a "patent solution"
