Hi,
I want to use my r/c electric plane motor and prop to make a fan that I can use to run off a car battery. The battery is 12V. The battery pack that is for the planes motor is 8.4V.
What is the best way to drop it from 12v to 8.4v?
I did read up about voltage regulators, but there is this thing called "vdrop" I think it was. That is like a dead spot in the voltage range where you need to have a minium of say a 2v gap between the two voltages otherwise it will not work.
So that is one way I can think of to bring the voltage down. The other way would be to get an arduino and set up a PWM circuit. I wonder how much buzzing there will be, and and also if that would run my electric motor or not.
Any ideas?
