The terraPin OSKAR Tuxedo 6X9 pinhole camera is easy to print and assemble, requiring but a single lock nut and bolt for the shutter and a flanged 1/4-20 nut for the tripod mount. The 29 mm ‘focal length’ provides for a wide angle (approx. 110 degrees) and just a bit of optical vignetting at the corners of the 6X9 frame, for a classic pinhole look. OSKAR is designed for a pinhole diameter of 0.23 mm, but that’s not a critical dimension. Exposure charts for a variety of films are included in the Thing Files.
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
