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 pictures.
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 those who do not know, a pinhole digicam, briefly, is a light-proof case with a tiny gap on one facet which replaces the lens. Mild is let in by the outlet, creating an inverted picture of the surface world/topic onto the movie or reverse facet of the field.
Schlemmer now prints principally together with his LulzBot TAZ 4, in addition to just a few RepRap machines he constructed from scratch. He typically makes use of PLA, however seeks any materials with excessive opacity, as he can not let any mild into the chamber in addition to the specified quantity by the pinhole.
“My cameras are referred to as terraPin,” describes Schlemmer, “they usually can be found in a wide range of codecs and configurations.” He has designed many different elements for cameras, however the terraPin household seems most distinguished. Try a few of 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 point of interest 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 may be very vast. “The Prime makes a traditional pinhole publicity with darkish corners and a vivid 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 images which can be unattainable to make with a set lens digicam,” clarifying that “because the movie is curved, the body could be very vast with a uniform publicity throughout all the body.”
The Kaiju is a 6X18 panoramic digicam with a radially concentric pinhole and a round movie ‘aircraft’ – this enables the consumer to seize actually vast 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 pictures per roll of 120 movie,” says Schlemmer. When the Bijou is used usually, 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 facet, thus the identify.” So, with the Sidewinder, you get the perfect of each vertical and horizontal pictures.

terraPin 2-Headed-Turtle
Primarily based 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 may be very near the space 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 images, you possibly can “trick your eyes” whereas adjoining prints, or you should utilize 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 – strive it under!

These are just some examples of Schlemmer’s rising digicam assortment. We have now just a few posted in our Design Library, or you possibly can examine them out on Thingiverse.
