How to DIY your own Magnetic Stirrer V2 (better than first version)

After I've published the first instructable about how to make a magnetic stirrer and after the constructive criticism I've got, I decided to make a new Magnetic Stirrer, an improved one.
Then I start the research for what materials should I use for it. I make the circuit, the design of the case and then I assembled it.
I hope you will like it, and by the way, you can also use it in many ways.

What did you make?
I made a Portable Magnetic Stirrer that can be used in the chemistry lab, home or everywhere you want yo use it. It is more efficient and it has more features than first version so as it would be a pleasure to use it. As I said above, it could be use in many way, not only as a magnetic stirrer. 

How did you make it?
Making it wasn't very hard, but to make one you need patience and time, patience for possible errors that can appear during you make it, and time for work. I started searching for a case for it, not too small, not too big. Then I continued seeking for a geared motor, which is little and efficent. After I've got it, I search for a metal disc and some strong magnets. When I finished getting all things I need (you will find a materials list next step), I made the circuit, I chose a design for the case and I painted it.

Where did you make it?
I made it home and at school, during breaks.

What did you learn ?
By making this project, I learn that almost everything can be recycled and reused for other porposes, like my project. Almost everything piece of it was recycled. The geared motor is from an old CD-ROM, the case is a CDs case...It was a bit tricky to make it customisable, but not impossible. And it was a challenge for me to make the circuit as small I can.

Let's start the work.

Nice, tight, efficient design.

I particularly like your use of as much recyclable material as possible.

I hope that you're not the only one who like my project.

Thank you.

Much better than previous! Well done, Andrei!
That's the way: make something that work, then make it better!

Two small corrections: the diameter of "filled transparent plastic tube" is 0,3 cm and the diameter of "plastic hose" is 0.5-0.7 cm. In your text this dimensions are too small.
