einstein: You can't just choose random component values without knowing what the hell you're doing. With a 4700 µF cap, you'd nearly short out the rails on each cycle. The current spikes will cause you a lot of problems. But if you have a +5V power supply, and transistors, which can handle 10-20A peak current, (subject to be limited by wire resistance and capacitor ESR) and you don't mind the microcontroller rebooting a few times due to a brownout condition during startup, and maybe later too, then go for it.
(Or put if you can't see through the layer of sarcasm, no, you're doing it wrong.)
