The Heart of Maker Faire

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”.

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.

World Maker Faire

We’ll be attending World Maker Faire in New York on the 23rd and 24th of September. Will you be there?
