Imagine a professor who takes you and two good fellows and says these words:
"Well, you have to make this neodimyum-made sphere levitate with a couple of magnets and some inductance, resistance, capacitors and transistors. It should react to external interference and remain still in mid-air at five-six centimeters from your electromagnet.
You have a month, plus some week if it's too much difficult. Good luck."
This is my case.
And that damn sphere is still not levitating.
I'm optimist since we have something like 60% problems solved, but it's still difficult...
Meanwhile, I'm back, at least on weekends:)
