I've been wanting to sit down and finish soldering sync cables since December, but finally got around to doing it. (Not having to worry about setting off a smoke detector or trying to complete the task outside with bitter winter wind also helped, oh, and a proper iron too.)
While waiting for bits to heat up, I broke out an old macro bellows thingy and grabbed a few shots of the clutter on my desk.
Aperture dial on an old 50mm lens
ISO "reminder" dial on the film magazine to a medium format camera. It has no actual controls, just reminds you what speed you've got loaded. Funny that it tops out at ISO650 too.
