Where did you get that dc motor with that metal plate? I am trying to find one.

Thanks

[Ubojica6661]

I made it for $2

This is a very good demonstration! One question though, won't you waste a lot of energy in the rheostats? Why not use a linear regulator or transistor?

[Cforchemistry]

It actually waste a lot of energy, PWM is the best to control such motor. However, rheostat is cheap and readily avaliable.

Why use two potentiometer and not just one?

[Cforchemistry]

I use one at first, but I found using two is better for me to control the speed.

i would like to have one of it (=

[Cforchemistry]

You can make one easily

[polanskiman]

@Cforchemistry Could you please provide schematics then :p. Ratings of all used material (power supply, motor, rheostasts... )

[ChemHow2]

Great Video, I love the logo!

Keep up the good work, 5stars once again.

[Cforchemistry]

You can also make one yourself

[Kuwaiti55]

I've always wonder how this stuff works

Did the magnet attach on a motor?

[Cforchemistry]

The magnet is attached to the metal plate on the motor, which the motor spin and spin the stirrer bar too.
