Rescuing Old Film with Raspberry Pi @Raspberry_Pi #PiDay #RaspberryPi

via RaspberryPi.org

When Electrical Engineer Alan Platt was given the task of converting old cine film to digital footage for his father-in-law’s 70th birthday, his first instinct was to look online.

“There are plenty of companies happy to convert old films”, he explains, “but they are all extremely expensive. In addition, you have to send your original films away by post, and there’s no way to guarantee that they’ll be safe in transit.”

Alan was given a box of Super 8 films covering 15 years of family holidays and memories. A huge responsibility, and an enormous challenge. Not content to let someone else do the hard work, Alan decided to convert the films himself — and learn how to program a Raspberry Pi at the same time.

Alan’s initial plan involved using his father-in-law’s cine projector as the base for the conversion process, but this soon proved impossible. There was no space in the projector to house both the film-playing mechanism, and the camera for the digitisation process. Further attempts to use the projector came to an end when, on powering it up for the first time, the 50-year-old machine produced a loud bang and a large cloud of smoke.

Undeterred, Alan examined the bust projector’s mechanism and decided to build his own. This began with a large eBay order: 3-D printed components from Germany, custom-shaped PTFE sheets from the UK, and optical lenses from China. For the skeleton of the machine, Alan’s box of Technic LEGO was dusted off and unpacked; an old TV was dug out of storage to interface with the Raspberry Pi Zero.

As 2022 starts, let’s take some time to share our goals for CircuitPython in 2022. Just like past years (full summary 2019, 2020, and 2021), we’d like everyone in the CircuitPython community to contribute by posting their thoughts to some public place on the Internet. Here are a few ways to post: a video on YouTub, a post on the CircuitPython forum, a blog post on your site, a series of Tweets, a Gist on GitHub. We want to hear from you. When you post, please add #CircuitPython2022 and email circuitpython2022@adafruit.com to let us know about your post so we can blog it up here.

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.
