Re: 3vdc motor PWM problem


Sam, if you want me to take a picture of the pump from the aquarium air pump
I will. By controlling the amplitude of the pulse on the coil that pushes
the pump chamber - you control the amount of fluid it pumps per pulse. This
pump is small, not the size of the whole air pump as it don't use the 120
volt coil.
You said in another post that you would prefer not to make the pump yourself
but is that not the fun of it?
I am also going to build a few of these for Christmas presents as it would
truly make unique gifts. Thanks for the inspiration :)

Yea a picture would be great. Have you tested it out? I'd like how
well it performs.

My best results are 22 drops/second, 6mm drop diameter.
