Bitmain Antminer S3 - can it work?

Just wondering if anyone has any experience or tips on using ASIC technology, for Hashing or other processing.

I know Bitcoin machines are diffferent technology than graphics cards, but they process math in the same way (right?).

Any ideas or advice where to start?

thanks in advance,

PS: I've got an Antminer S3 operating at 241.81 GH/s for bitmining not clocked running OpenWrt.
