Just a quick update on progress with this project. All of the parts, including the 3D printed pieces (Shapeways) and PCB (Fritzing) have been ordered. I'm going on vacation until the 26th, so I probably won't be able to update until then.

Edit (March 24 2015):

I've shot through another two rolls with the Canon P, and I'm still loving it. I'm still adjusting to focusing by rangefinder (coming from many SLR/TLR's) but it's a fun process. I can only imagine it'll get better with a TTL meter in it!

I return to Seattle in another two days, and the Fritzing/Shapeways parts should have arrived by then. By no means am I looking forward to going back to Washington from Hawaii, but the prospect of a project ready and waiting for me at home softens the blow a bit!
