DIY Portable Magnetic stirrer in action!

IMPORTANT:
All content here meant to be Educational,None of the above experiment should be repeated on your own.

This is a stirrer I made previously for my experiment, it is a very common apparatus in laboratory.Although I have the commercial one, I made this to serve the demonstration where portability is critical. I hope you can get an idea how a magnetic stirrer work, and eventually get some inspiration if you plan to make one!

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.

[LY1113]

i would like to have one of it (=

[Cforchemistry]

You can make one easily

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

Thanks

I made it for $2

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