These modded scanners let you play techno using barcodes
Every so typically, a tweet goes viral displaying somebody making a beat by wielding two barcode scanners in entrance of a sheet of varied line patterns. It’s like cyberpunk grocery checkout with a touch of Aphex Twin, and through the years, these movies have racked up thousands and thousands of views, shared by the likes of artists like Shawn Wasabi and membership tradition tastemaker outlet Boiler Room. But I’m at all times shocked that the clips largely keep constrained to the circles of social media and Reddit.
The different week, one other certainly one of these movies went viral (it has 1.9 million views on Twitter on the time this text was printed), and I gave in. I needed to know two issues: who’s behind this barcode techno, and the way do they make it work?

The barcode participant within the video is Ei Wada, aka Crab Feet, a Japanese artist and musician who rebuilds outdated digital home equipment into musical devices. He’s participated in an orchestral venture using 20 reel-to-reel tape recorders, supplied music for 11 Issey Miyake Paris reveals, and created artwork, music, and tech group Electronicos Fantasticos. The barcode venture was made beneath that group’s umbrella again in 2018, and so they’ve been performing iterations of it ever since.
As far as the way it works, Wada doesn’t present a lot aside from saying that the barcode scanners are modified and generate sounds by connecting scanned indicators “directly to the audio terminal to output sound.”
The printed backdrop doesn’t have barcodes within the conventional sense since a barcode is a sample of black and white bars of various thickness. Usually, the sensor in a scanner interprets mirrored mild from barcode traces, turns it right into a little bit of textual content a pc can perceive, after which the barcode system emits a beep to verify a profitable scan. The packing containers seen within the Electronicos Fantasticos video embody barcodes in addition to issues like starbursts and low-contrast patterns.
Over on Reddit, customers surmise how the scanners learn values with a purpose to morph the sound. Parameters just like the pitch and velocity look like managed by numerous actions, like shifting nearer or farther away, how briskly the scanners transfer, tilting the scanners, and aiming them at completely different blocks of patterns. As consumer xix_xeaon says, “ELI5: You can think of the images as sound samples, and the scanners are controls to play certain parts of the sounds with various different settings.”
Aside from all the barcode-inspired stuff, Wada’s additionally turned small CRT televisions into ukulele-type devices, modded a reel-to-reel tape recorder into one thing resembling an accordion, and flipped a manufacturing unit fan right into a bass guitar.
Honestly, no matter how the barcode scanners work, I like outdated repurposed tech, and maybe even extra, Wada’s description of the venture. “In the future, barcode readers will be connected not only to cash registers but also to speakers,” he writes. “DJs with daytime cash register and barcode at night. The next level of cash register!”
