Hello guys,
I'm building the light electro-mechanical shutter from a Hard disk drive mentioned here:
**broken link removed**
So I opened a hard-disk (different kind), and took the shutter part (as shown in the pictures), and by putting current in the coil, we can control the shutter. So, to drive the shutter effectively, there's a circuit to be designed (also available in the same page):

The coil of the hard-disk I have has a resistance of 6 Ohms, but I don't know whether this circuit is valid to drive it. There are big capacitors in the circuit, and I'm afraid I'd burn stuff, where the circuit drives almost 3 Amps.
How should I look at this matter? should I just design the circuit blindly and just use it? or should I do some relevant calculations before building the circuit?
Thank you for any efforts.
