Lux Camera

My goal is to design and produce a fully-fledged camera, using easily purchased off-the-shelf components, without having to rely on anything pulled from a potentially valuable piece of equipment. A secondary goal is also to make this camera completely open source through rapid-prototyping techniques such as laser cutting and 3D printing, and the Arduino physical computing platform.

Type 6x6 Box Camera
Media 120 Roll Film
Objective 65mm f/5.6 Single Element, Coated
Viewfinder Waist-level Brilliant finder
Shutter Electromechanical single-leaf, 1/125-1s + B&T
Aperture Rotating diaphragm, f/5.6-32
Dimensions 7.9 x 9.4 x 11.7 cm
Construction SLS Polyamide (body), Stainless Steel (shutter, aperture)

You'll need to install the Arduino IDE and Trinket drivers available from Adafruit. Adafruit has a version on the Arduino IDE compatable with Trinket
(https://learn.adafruit.com/introducing-trinket/setting-up-with-arduino-ide).

You still need to install the Trinket USB drivers (https://learn.adafruit.com/introducing-trinket/starting-the-bootloader).
The Trinket bootloader isn't as plug-and-play as say, an Uno.
Arduino Code

There are additional parts!
You will need this file to make metal parts for the aperture wheel, shutter, pressure plate, focus distance scale, etc. A laser cutting service like Pololu will know what to do with this file. (Note! There is a typo - these should be cut from 0.025" stainless steel)
Email me for the file!
