Digitising film reels with Pi Film Capture

via Raspberry Pi

Joe Herman’s Pi Film Capture project combines old projectors and a stepper motor with a Raspberry Pi and a Raspberry Pi Camera Module, to transform his grandfather’s 8- and 16-mm home movies into glorious digital films.

We chatted to him about his Pi Film Capture build at Maker Faire New York 2016:

What inspired Pi Film Capture?

Joe’s grandfather, Leo Willmott, loved recording home movies of his family of eight children and their grandchildren. He passed away when Joe was five, but in 2013 Joe found a way to connect with his legacy: while moving house, a family member uncovered a box of more than a hundred of Leo’s film reels. These covered decades of family history, and some dated back as far as 1939.

This provided an unexpected opportunity for Leo’s family to restore some of their shared history. Joe immediately made plans to digitise the material, knowing that the members of his extensive family tree would provide an eager audience.

Building Pi Film Capture

After a failed attempt with a DSLR camera, Joe realised he couldn’t simply re-film the movies — instead, he would have to capture each frame individually. He combined a Raspberry Pi with an old Super 8 projector, and set about rigging up something to do just that.

He went through numerous stages of prototyping, and his final hardware setup works very well. A NEMA 17 stepper motor  moves the film reel forward in the projector. A magnetic reed switch triggers the Camera Module each time the reel moves on to the next frame. Joe hacked the Camera Module so that it has a different focal distance, and he also added a magnifying lens. Moreover, he realised it would be useful to have a diffuser to ‘smooth’ some of the faults in the aged film reel material. To do this, he mounted “a bit of translucent white plastic from an old ceiling fixture” parallel with the film.

Software solutions

In addition to capturing every single frame (sometimes with multiple exposure settings), Joe found that he needed intensive post-processing to restore some of the films. He settled on sending the images from the Pi to a more powerful Linux machine. To enable processing of the raw data, he had to write Python scripts implementing several open-source software packages. For example, to deal with the varying quality of the film reels more easily, Joe implemented a GUI (written with the help of PyQt), which he uses to change the capture parameters. This was a demanding job, as he was relatively new to using these tools.

The top half of Joe’s GUI, because the whole thing is really long and really thin and would have looked weird on the blog…

If a frame is particularly damaged, Joe can capture multiple instances of the image at different settings. These are then merged to achieve a good-quality image using OpenCV functionality. Joe uses FFmpeg to stitch the captured images back together into a film. Some of his grandfather’s reels were badly degraded, but luckily Joe found scripts written by other people to perform advanced digital restoration of film with AviSynth. He provides code he has written for the project on his GitHub account.

For an account of the project in his own words, check out Joe’s guest post on the IEEE Spectrum website. He also described some of the issues he encountered, and how he resolved them, in The MagPi.

What does Pi Film Capture deliver?

Joe provides videos related to Pi Film Capture on two sites: on his YouTube channel, you’ll find videos in which he has documented the build process of his digitising project. Final results of the project live on Joe’s Vimeo channel, where so far he has uploaded 55 digitised home videos.

We’re beyond pleased that our tech is part of this amazing project, helping to reconnect the entire Herman/Willmott clan with their past. And it was great to be able to catch up with Joe, and talk about his build at Maker Faire last year!

Maker Faire New York 2017

The Heart of Maker Faire

via Raspberry Pi

We at the Raspberry Pi Foundation find it incredibly rewarding to help people make and share things they love. It’s amazing to be part of an incredibly creative community of makers. And we’re not the only ones who feel this way: for this year’s Maker Faire UK, the team over at NUSTEM created the Heart of Maker Faire, a Pi-powered art installation that is a symbol of this unique community. And to be perfectly frank, it’s bloody gorgeous.

The Heart of Maker Faire

NUSTEM’s new installation for Maker Faire UK 2017, held on 1st & 2nd April at the Centre for Life, Newcastle-upon-Tyne. Visitors wrote notes about things they love, and sealed them in jars. They then read their heart rates, and used the control boxes to associate their jar and heart rate with a space on the shelves.

A heart for the community

NUSTEM is a STEM outreach organisation from Northumbria University, and the makers there are always keen to build interactive projects that get people excited about technology. So at this year’s Faire, attendees passing their installation were invited to write down something close to their heart, put that note in a jar, and measure their heart rate. Then they could connect their heart rate, via a QR code, to a space on a shelf lined with LEDs. Once they placed the jar in their space, the LEDs started blinking to imitate their heart beat. With this art piece, the NUSTEM team wants to say something about “how we’re all individuals, but about our similarities too”.

Still beating. Heart of #MakerFaireUK

Making the heart beat

This is no small build – it uses more than 2,000 NeoPixel LEDs, as well as five Raspberry Pis, among other components. Two Pi 3s are in charge of registering people’s contributions and keeping track of their jars. A Pi Zero W acts as a central hub, connecting its bigger siblings via WiFi, and storing a MySQL database of the jars’ data. Finally, two more Pi 3s control the LEDs of the Heart via a script written in Processing. The NUSTEM team has made the code available here for you “to laugh at” (their words, not mine!)

A heart for art

Processing is an open-source programming language used to create images, graphs, and animations. It can respond to keyboard and mouse input, so you can write games with it as well. Moreover, it runs on the Pi, and you can use it to talk to the Pi’s GPIO pins, as the Heart of Maker Faire team did. Hook up buttons, sensors, and LEDs, and get ready to create amazing interactive pieces of art! If you’d like to learn more, read Matt’s blog post, or watch the talk he gave about Processing at our fifth birthday party earlier this year.

It’s been five years since we made our first appearance at Maker Faire New York. Back in 2011, we were still showing demonstrations of the Raspberry Pi, prior to its release the following spring. This year, we had prominent billing alongside the robots and rockets!

Robots, rockets, and Raspberry Pi!

Maker Faire New York ran from 1-2 October, and was as great an experience as ever. We brought a bunch of Raspberry Pis showcasing our brand-new Pixel desktop environment. Greg Annandale’s gorgeous photo of the Brooklyn Bridge was a stunning backdrop to the Sense HAT activities we had organised.

Joining the stalwart US Pi team of Matt and Courtney were Carrie Anne, Sam, and Lorna, as well as Raspberry Pi Certified Educator Kerry Bruce, who came all the way from Albuquerque, New Mexico. A community college instructor with a passion for STEM education, Kerry was a real trouper and a valuable addition to the team.

When we arrived at Corona Park to get set up, we were concerned about the inclement weather. Given that the Faire is outside, the prospect of running our Pi activities in an open-sided marquee was somewhat daunting.

The team tried hard not to let the rain dampen their ardour for STEM...

We braved the elements to take a photo in front of the famous Unisphere, to explore the park a bit, and to geek out over the history of the place. I can’t have been the only one who was excited to see the towers on the New York State Pavilion in real life, after multiple viewings of Men in Black.

Fortunately, the weather improved for the Faire; we didn’t have to remove electrical equipment from puddles! Resident design genius Sam decorated our tables with Pi-themed cartoons, including one answering this common question: how do you connect a Raspberry Pi to a computer?

Here’s what happens when @samalderhyde shows up at your event! #MakerFaire #wmfny16 @makerfaire

We loved pointing to Sam’s cheery Pi character when explaining that the tiny board was the computer. It was great to see people’s surprise at the Pi’s power.

Matt and Carrie Anne both gave speeches: Carrie Anne’s presentation, “Digital Making: Encouraging Creativity in the Classroom and Integrating STEAM Project-Based Learning”, was part of the Make: Education series, while Matt explained how to get started with the Raspberry Pi on the Show and Tell stage.

Go see @MattRichardson at @makerfaire’s Show & Tell Stage at 11:30 (in 10 min). He’s giving a intro to Raspberry Pi.

We heard great reports from the attendees, and we saw a lot of visitors to the stand who had been enthused by what they heard. 

As in previous years, there were many excellent Raspberry Pi-based projects, as well as familiar faces from the Pi community. There was an excellent display of Pi-controlled Lego Mindstorms robots. We also met the guys from Pi Supply showcasing their new JustBoom equipment, bringing affordable high-quality audio to Raspberry Pi users. Eager experimenters of all ages came to try out our Sense HAT activities, and to tell us about the Pi projects they had made at home. One man was even wearing a Pi Zero as a necklace! Other visitors included Steven Welch, who updated us on the work his team are doing with Pis at CERN (we’ve blogged about this), and Henry Feldman of the Beth Israel Deaconess Medical Center, who is using the Raspberry Pi and Camera Module for edge detection in laparoscopic surgery.

We also found a number of excellent projects with more artistic applications. Joe Herman had uncovered a cache of old 8mm and 16mm family movies, and was digitising them and projecting them via a modified vintage movie projector equipped with a Raspberry Pi and Camera Module. You can find out more on Joe’s GitHub.

Joe’s project wasn’t the only great Pi art project. Following on from Sam Blanchard’s amazing SeeMore, one of the main showpieces of last year’s Faire, we were incredibly excited to see another Pi-powered art piece in pride of place this year. The first thing to greet attendees visiting the Faire in the New York Hall of Science was the Pi-powered Sisyphus kinetic art table. We think it’s so amazing, we’ll be devoting a whole post to it, so keep an eye out!

For several of us, it was our first visit to the Faire and to New York, which really added to our excitement. One of the greatest things was meeting so many happy Pi fans, and introducing newcomers to the fun you can have with one. We lost count of the excellent animations we saw kids (and adults) create on the Sense HAT, and the joyful exclamations as another person got their first piece of Python code working; this is one of the most rewarding parts of our work. We can’t wait for the next Maker Faire! If you couldn’t attend, be sure to check out our tour video here:

A 3D-printed reimagined Game Boy prototype

via Arduino Blog

With a shape reminiscent of a Game Gear, revised controls and hardware, Anthony Campusano’s rig looks extremely fun!

As reported on 3DPrint.com, Campusano’s Game Boy-inspired prototype was quite the crowd-pleaser at World Maker Faire in New York. Although wider than it is tall (like most portables to follow), and with many more buttons, this handheld console still screams “original Game Boy.” Perhaps this is because of its color scheme, or even the angle of the buttons.

Hardware consists of several platforms, including an Arduino to handle tasks such as status lights and battery level. The idea was inspired by Florian Renner’s similar concept, though he replaces the ideal of separate game cartridges with an SD card for storage.

I’m a trained architect, though I have industrial designer envy. In terms of electronics, I’m self-taught. When it comes to machine specs, the handheld is based on an Intel Core M. Controls are Teensy-based, and the status lights and battery level, etc. are run from an Arduino. Estimated battery life is about 3hrs +/- depending on the game.

You can see more photos of Campusano’s project on his Facebook page, and read all about it on 3DPrint.com.
