Thank you for the tips again, gentleman.
I got it now what's with the logarithmic curve: It's normal.
Since adjusting PWM adjusts linearly driver's current-output, it's only logical that our "constant" current driver ramps up the voltage, which together with linearly raising current acts as a logarithmic wattage scale.
I (kind of) knew that part. Sorry for maybe mixing terms or facts. (That's also what our PM said, after getting caugth lying that he's proposal has 90-10 support. Actual numbers were opposite. ) It's just not exactly clear for me what "bipolar transistor" means, but I've had the impression that most people mean those when talking about transistors (at least on Arduino-community). While a rally car and a family wagon both are cars, other we call a car and another we call a rally car.A MOSFET is also a transistor
