I wanted to focuse that even with NiCd batteries, for what the circuit was actually 'designed' in the link, the circuit will not work reliably.

I understand that emotions can rise up. That's typically for us men, having so much testosteron in our blood. I am becoming angry too, when someone is not accepting good arguments. But why becoming angry before having good discussion, at a moment when big arguments can still help us to keep a cool head?
