On top you can see the circuit (arduino, op-amp, dip-switch, and push-button) that controls the shutter mechanism. Farthest to the right is the lens-aperture-shutter module. In the middle is the focusing module (this module is stationary and the first module slides in-and-out to focus). The largest wooden rectangular prism (on the left) is the film/digital-back module, which in this instance connects to my Nikon d90.
