Construction of an open source rail for motion-controlled time lapse photography

Arduino Uno
Arduino Proto Shield (Use Arduino's own brand if following the developer's instructions, but this can be adapted to any prototyping shield.)
Header Pins
DB-9 Female Connector
DB-9 Male Connector
Wire, various colors
4 momentary pushbuttons, suitable for rugged case use. I used item 69755K31 from McMaster-Carr.
DryLin W16-A Linear Motion System (Amazon.com)
1/4 - 20 Right Hand Acme Screw (Roton) You need about one meter. Order 40 inches and cut to fit. I ended up ordering two to make Roton's minimum order, and was glad when I screwed up cutting my first one.
1/4 - 20 Right Hand Acme Flange Nut (Roton)
Stepper Motor Driver Carrier (Pololu) This is the one the developer recommends. I went with a drop-in replacement that has better heat tolerating characteristics.
Small Heat Sink (Sparkfun) Optional, depending on which motor you choose. See the developer's notes.
7-Segment Serial Display (Sparkfun) I linked to the yellow version, but choose any color.
Optoisolator with Darlington Driver (Sparkfun)
2 1KΩ Potentiometers (Parts Express)
2 3.5mm Stereo Panel Mount Jacks (Parts Express) Developer recommended these; but I went with beefier Switchcraft jacks.
2 Miniature Snap-Action Micro Switches with Lever (Parts Express)
2 knobs (Parts Express) Developer specified some other knob, but I love these chickenheads.

Developer Chris Field hosts his instructions on Sourceforge. Some of the written documentation is there.

Some of the documentation is only available in video form, at Vimeo.
