If the really good intentioned people on this forum want to help others learn, they will have a step by step course plan. Not the self centered shotgun blast exampled above.
Why don't you show how the simple ebay device can teach someone about electrolyte concentration, temperature, voltage and current, etc.
Then move forward.
