Zeros and ones

This should be easy, but short of writing something specific to do it,
I am not getting my head around how.
It is easy and convenient to use /dev/zero to write out a number of
zero bytes to somewhere - as in:
dd if=/dev/zero of=zerofile bs=512 count=1770000
dd if=/dev/zero of=/dev/da1 bs=512 count=1770000
But, I would like to write all ones - as in 0xff or maybe some
other pattern - as if there was a /dev/one also.
Is there a nice way to do this using UNIXistic stringing existing
stuff together? Or do I have to write a little piece of code?
Thanks for any [positive] suggestions.
