This is a very simple yet effective pinhole camera that I came up with out of necessity. I wanted something small, tripod mountable, and very quick to make and reload.
The lid simply snaps on and off without needing complex clip mechanisms, and the exposed film winds into a second reverse mounted film canister to stop accidentally exposing all of your film if you absentmindedly open it. It should also be noted that one full turn on the advance dial is one frame of film, so it’s intuitive and simple.
When assembling the camera be sure to file/sand the front of the camera body, shutter blade, and shutter housing smooth so that the shutter blade moves freely.Be sure to clean out the hole for the shutter pin on both the body and the shutter housing before assembling.
The knobs should all be an interference fit and simply snap together.
As for the lens, brass shimming, or the aluminium film from a Milo tin should do the trick, be sure not to make the hole too big, and smooth off the burrs off with some fine emery paper. I made an exposure chart which can be printed and stuck into the indent at the back of the camera body, there are two versions depending on what size hole you go for. This chart should be printed at 37mm x 66mm.
I made a video showing a very quick and rough assembly which should give you the general idea, this thing is dead simple and don’t forget to enjoy the tripod screw at the bottom!
I’ll have a 120 version out in the next few weeks if anyone is interested.

Every Thursday is #3dthursday here at Adafruit! The DIY 3D printing community has passion and dedication for making solid objects from digital models. Recently, we have noticed electronics projects integrated with 3D printed enclosures, brackets, and sculptures, so each Thursday we celebrate and highlight these bold pioneers!

Have you considered building a 3D project around an Arduino or other microcontroller? How about printing a bracket to mount your Raspberry Pi to the back of your HD monitor? And don’t forget the countless LED projects that are possible when you are modeling your projects in 3D!

The Adafruit Learning System has dozens of great tools to get you well on your way to creating incredible works of engineering, interactive art, and design with your 3D printer! If you’ve made a cool project that combines 3D printing and electronics, be sure to let us know, and we’ll feature it here!
