Threshold, or levels or curves (I went with Threashold)

Some Gausian blur to smooth it up a bit, followed by levels, curves or threashold again. I actually gave it a low value Gassian blur after this to give it some antialiasing.

Scale it to suite, which means start with a big canvas if you want to end up with a tighter pattern.

For white edges you could use an Inner Glow Layer Style.

Couldn't resist making more automated than an action. No error checking, so you have to be careful what you enter.
