We love when 3D printing collides with long-standing hobbies. Enter: Todd Schlemmer, our September Hacker of the Month, and his ardour for pinhole cameras and images.
Schlemmer has been constructing pinhole cameras for a number of years out of conventional carpentry and papercraft. He began 3D printing his cameras in 2012 as soon as he constructed his Printrbot Plus package: “I used to be delighted by my preliminary outcomes,” states Schlemmer, “and I’ve continued to develop and refine new digicam designs.”
For people who do not know, a pinhole digicam, briefly, is a light-proof case with a tiny gap on one aspect which replaces the lens. Gentle is let in via the opening, creating an inverted picture of the surface world/topic onto the movie or reverse aspect of the field.
Schlemmer now prints largely together with his LulzBot TAZ 4, in addition to a couple of RepRap machines he constructed from scratch. He typically makes use of PLA, however seeks any materials with excessive opacity, as he can’t let any mild into the chamber in addition to the specified quantity via the pinhole.
“My cameras are referred to as terraPin,” describes Schlemmer, “and so they can be found in a wide range of codecs and configurations.” He has designed many different parts for cameras, however the terraPin household seems most outstanding. Try among the terraPins under.
terraPin Prime
“The terraPin Prime is a 6×6 format, with a ‘focal size’ of about 27mm,” explains Schlemmer, including that “tright here isn’t any focus in a pinhole digicam, however the time period is equally as helpful for calculating angle of view and movie quantity.”
This digicam is able to photographing each vertically and horizontally at about 90 levels, which could be very extensive. “The Prime makes a basic pinhole publicity with darkish corners and a vibrant middle,” he describes, clarifying that that is as a result of “variation within the quantity of sunshine that hits the movie throughout the body.”

terraPin Kaiju
Schlemmer states that the terraPin Kaiju “makes photographs which are unimaginable to make with a hard and fast lens digicam,” clarifying that “because the movie is curved, the body will be very extensive with a uniform publicity throughout all the body.”
The Kaiju is a 6X18 panoramic digicam with a radially concentric pinhole and a round movie ‘airplane’ – this permits the consumer to seize actually extensive photographs in a single shot.

terraPin Bijou Sidewinder
The Bijou Sidewinder is a variation of the Bijou, which “shoots an oblong 6×4.5 body and will get 16 photographs per roll of 120 movie,” says Schlemmer. When the Bijou is used recurrently, it shoots in portrait orientation, which is actually a vertical shot.
“The Sidewinder variation permits for mounting on a tripod in both panorama or portrait compositions,” he explains, “when capturing panorama, the knobs are on the aspect, thus the identify.” So, with the Sidewinder, you get one of the best of each vertical and horizontal photographs.

terraPin 2-Headed-Turtle
Based mostly on his authentic 6×6 terraPin, Schlemmer developed a stereo pinhole digicam dubbed the 2-Headed-Turtle. “This digicam makes a stereographic pair of exposures concurrently,” he states, increasing that “the two exposures are 61mm aside, which could be very near the gap between human eyes, so the 3D impact feels pure when viewing.”
On the 2-Headed-Turtle’s web page on Thingiverse, Schlemmer explains that “to view the stereo pictures, you may “trick your eyes” whereas taking a look at adjoining prints, or you should use a viewer designed for both slides or prints.” For the trick, isolate the image, and cross your eyes – the middle picture will look 3D. “It is superior,” smiles Schlemmer. We utterly agree – attempt it under!

These are only a few examples of Schlemmer’s rising digicam assortment. We’ve got a couple of posted in our Design Library, or you may test them out on Thingiverse.
