He makes a little noise and also quite a bit of wind (for me a little too much)
But the noise does not come from the fan - I have broken down and rebuilt the whole thing.
There are potentiometer (variable resistor) I've hung between them, 100 ohms potentiometer.
Simply hang between power supply and motor.
That makes what noise that is the rotary motion, the bells and whistles is.
These are 3 small gears and make the move right noise. I walk with a little effort, since the rest is in the box.
In my now no longer alone turns, he is running as fast as I want.
He is 40cm away from me, makes a slight breeze and beautiful looks damn good.
Whoever trusts to a conversion (3V DC) can not really happen that has a beautiful and quiet fan.
Provided a switching power supply to at 3V and one has the possibility to operate the stationary and mobile (with normal 1.2V AA batteries or batteries). What more do you want.
With Ready-2-use batteries of the fan runs smooth 2x 8 hours. The colleagues envy me to work for it: D
Back there is a small box (the one can open) in there are the gears.
Simply gears rausmachen (now he no longer turns to the left / right) in this little box is space for a small potentiometer - for example, there when you moved well the additional cable Reichelt, he looks like the original. But turns just as fast as you want it, the effort and costs 20 cents for the potentiometer are worth my 4 stars.
Who only just a fancy fan wants, which makes air well, can also strike who it wants to quietly build him around;)
