On my way into town this morning, I stopped by Walmart to return an old truck battery. Found this:
I figured, "well ****, if a redneck can make a bacon bowl, I can certainly solder!"
Went down to Radio Shack, picked up some goodies. Namely:
62/36/2 Rosin-core Solder (1.5 oz roll)
Desoldering Vacuum Bulb
Misc project wire
A 500-pack of assorted resistors (they didn't have any 270 ohm loose)
A rigid jumper wire kit for breadboards
Haven't soldered in over 10 years, since I had to build an FM transmitter to retrofit an RC aircraft. Watched a quick refresher video to re-familiarize myself with the finer points of soldering:
Jumped right in, using only a scrap piece of cardboard, soldering station and wet sponge. I don't think my results are professional-grade, but they look like they'll get the job done.
Parts from the kit:

First row of the IC socket done (soupy looking stuff is rosin that hasn't dried yet):
IC socket completed, plus the two 8-port ground headers (top row) and two 8-port I/O headers (second row). The capacitor at bottom was certainly the hardest joint. I know it looks like I bridged there, but it's just the viewing angle. There's a pretty decent gap between them.
GPIO header soldered on (bottom right rows), MCP23017 read to snap in.
Total build time was about 45 minutes. Would have been much shorter, but I was taking my sweet time.
If you're buying solder, grab .032" instead. With .022", the feed rate was pretty fast. Hard to stay steady at that rate.
Bend the capacitor pins to hold it in place. Don't fight with gravity while trying to solder.
My iron came with an ST2 tip. It was larger than most of the pads on this project. I would have felt much more comfortable with an ST1 tip or even smaller.
