Lux Camera

thingiverse

My goal is to craft and assemble an entirely self-contained camera, utilizing components readily available on the market, without relying on valuable equipment. A secondary aim is to make this camera completely open source through rapid prototyping techniques such as laser cutting, 3D printing, and the Arduino physical computing platform. Type: 6x6 Box Camera Media: 120 Roll Film Objective: 65mm f/5.6 Single Element, Coated Lens Viewfinder: Waist-level Brilliant Finder Shutter: Electromechanical single-leaf shutter, 1/125s to 1 second + B&T Aperture: Rotating diaphragm, f/5.6 to 32 Dimensions: 7.9 x 9.4 x 11.7 cm Construction: SLS Polyamide (body), Stainless Steel (shutter, aperture) Parts List: Electrical Part Qty Source Notes Adafruit Trinket 5V 1 Adafruit Adafruit Quarter-size Protoboard 1 Adafruit Transistors, TIP120 2 Adafruit Possibly overkill Diode, 1N4001 1 Adafruit Solenoid, 5V 1 SparkFun Rotary Switch, 10 position BCD DIP 1 Jameco Could be substituted by a 10K trimpot Rocker Switch, SPST 1 Jameco Resistors, 1/4W, Asst.

Adafruit has a version on the Arduino IDE compatible 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! 12blues@gmail.com Credit it to http://kadookacameraworks.com/open.html How I Designed This
