Kinograph is an astonishing thesis project from Matthew Epler, an artist and film historian. It’s a Pi-powered, open-source, scalable device for digitising old film stock, complete with the ability to stabilise images (another application for OpenCV) and recapture sound. A good DSLR camera is the most expensive part of the setup, at about $2000; the rest of the equipment comes to $1200. (Matthew is working on getting that figure down below the magic $1000.) Compare that to the $480,000 it would cost you to digitise 50 films on reels at a film lab, or the $175,000 it’d cost you to buy a Kinetta (the nearest commercial equivalent device) and a whole world of possibilities opens up. Film stock, be it celluloid, acetate or nitrate based, is not stable, and being able to record and save our film heritage is a pressing concern. We’ve already lost more than 90% of all silent movies, and around 50% of the films with audio made before 1950.
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.
