sorry i did not do the step by step i said i would until six months after the fact.
i'm pondering the idea of doing some iptv how-to's. if that happens then i'll link the vid.
as you see here, i wrapped some wire around a piece of wood that has notches spaced the same as the soic foot print. sand it flat so that you can set the chip on it. if you don't sand then it just falls off the round surface.
pin it down with a rubber band to keep it from moving while you place your first dab of solder paste and solder it. once it's been "tacked" down you may remove the rubber band.
i recommend applying the paste and soldering one at a time.
after you finished soldering and checking all your joints for good connections you may spread the legs out and bend them the way you want while leaving the "bridge" of wire for support. if you clip them before manipulating the wire you risk snapping off the pin from the chip.
when your all set and done go ahead and clip them and be careful while placing your chip as your still at risk of snapping them off.

Yeah, most of the cutting edge sensor chips do not even come in DIP anymore. We are lucky enough to have a local retailer here that sells reasonable adapters.
In a jam some UDMA ribbon cable, a machined DIP socket, and some steady hands also works.

I noticed sparkfun has quite a few breakout boards for different devices, including SOIC, in the form of a SOIC to DIP board. They have a few sizes, but seem to lack a 16 pin version. You could still put a smaller chip on a larger board, you'd just have some extra pins left over. Here's the 20 pin version. Though it may not be in 'true DIY spirit' to use one, I think there are far more interesting problems to tackle, and $3 is worth it to avoid the frustration of soldering those tiny $!%&ing things.

i solder 26ga copper wires to a machined pin DIP socket, and use a needle nose to bend them into like a rib cage with soic pitch. then just solder the chip on.
