So far, so good
The PCB arrived on schedule yesterday, and after the weekly GROCS meeting, I got started with assembling our actual prototype. Before I touched the PCB, I wanted to get basic serial communication working over Bluetooth. It turns out that our new PIC Microcontroller is so new, the manufacturer didn't finish updating the library that makes serial (USART) easy to implement. So I had to build the library myself, and got a simple test program working shortly thereafter.
And with that, it was time for circuit assembly onto the PCB. The moment of truth for the layout, and my soldering skills. The bluetooth connector was a little too close to the exposed pins on the back, so I angled it out a bit. Everything else kind of dropped into place. And when I powered it up, the example program I had written previously fired up and functioned just as it did in the breadboard. The In-Circuit Serial Programming port worked, too. However, several other parts remain to be tested, so we need to wait a bit before breaking out the champagne (or, alternatley, the sparkling grape juice if on University premises). Check out a time-lapse MPEG video of circuit assembly!
(Video made using our new Axis camera.)

Jeff, you're my hero!
That video needs calliope music playing behind it!

Awsome video. I'd say the camera quality is pretty good. It should be good enough to detect locations of blimps, right?

I hope so! In fact, that video was 640x512 or something of that sort. I have another version of the same video in the camera's native resolution -- 1280x1024! But it's 100MB and in XVid format, so not very crowd-friendly.
