there's even more if the target is x86 -- nasm/yasm, and masm (Windows).
there's also dev86 which hasn't been updated in a while, but seems to be
used in a few places still.

creating an assembler can certainly be a useful learning exercise.  going
beyond that, everything Nick said is certainly true -- it's already a pretty
competitive landscape, so you'd want to identify a significant shortcoming
to make yours stand out as something people would care about.

just don't morph into something like High Level Assembly (HLA) :).
