Dubbed “Lux,” the 6×6 box camera (120 roll film) was originally prototyped using an Arduino Uno (ATmega328). Key project components include include Adafruit’s quarter-size protoboard, transistors (TIP120), diode (1N4001), 5V solenoid, rotary switch (10 position BCD DIP), rocker switch (SPST), resistors, 7.4 battery, connectors (JST PH, JST BEC), and a momentary button (SPST w/LED).
Additional specs? PCX lens, positive meniscus lens, mirror, and an electromechanical single-leaf shutter.
“Until now, all of my camera- building efforts utilized parts repurposed from old, obsolete cameras, and for good reason,” Kadooka explained on the project’s official page. ”Each constituent part of the modern camera, from the shutter, lens, aperture diaphragm, and film transport, are much too complex and delicate for the average hobbyist to reproduce. Borrowing parts from old cameras is usually the go-to solution for most DIY’ers (myself included), however I don’t think this is a sustainable technique.”
As such, Kadooka’s primary goal is to design and produce a fully-fledged 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,” he added.
