Hackers Transform Discarded Vapes Into Musical Synthesizers, Turning E-Waste Into Art

A group of New York City makers is converting disposable nicotine vapes into functional musical instruments, offering an innovative solution to the growing e-waste crisis while promoting STEAM education and creative circuit design.

In a Brooklyn workshop, what begins as a hazardous electronic waste item—single-use nicotine vaporizers—ends as a surprising musical instrument capable of generating otherworldly electronic tones. The Vape Synth project, pioneered by a collective of tinkerers operating under the name "Paper Bag," represents an ingenious intersection of environmental upcycling, circuit design education, and creative musical expression.

The project centers on the Elf Bar BC5000, one of the most popular disposable vape devices on the American market, which has sold millions of units nationwide. While these devices are marketed as single-use and disposable, they contain remarkably sophisticated components: rechargeable lithium-ion batteries, pressure sensors, USB-C charging circuits with status LEDs, and compact plastic housings. Rather than allowing these resources to enter landfills, the Paper Bag collective developed a method to transform spent units into fully functional digital synthesizers.

The technical foundation of the Vape Synth comes from the legendary "Engineer's Mini Notebook" series by Forrest M. Mims III, specifically his chapter on 555 timer integrated circuits. The 555 timer, first introduced in 1971, remains one of the most versatile integrated circuits ever manufactured, capable of generating square waves, timing pulses, and oscillating frequencies—perfect for creating electronic music tones. By implementing the classic "astable multivibrator" circuit configuration from Mims's workbook, the makers create a variable-frequency oscillator that produces audible tones when connected to a small speaker.

What distinguishes this hack from simple circuit projects is the ingenious reuse of the vape's existing infrastructure. According to documentation published by the collective and reported by WIRED, the Vape Synth retains the original lithium-ion battery and charging circuit, eliminating the need for external power sources. The device uses photoresistors (light-sensitive resistors) mounted on the circuit board—players change the tone by covering these sensors with their fingers, varying the resistance and thus the frequency output. The original mouthpiece serves as the interface: drawing breath through it activates the pressure sensor, triggering the synthesizer circuit.

The environmental context makes this innovation particularly significant. Disposable vapes have created an unprecedented e-waste crisis. According to research by the Surfrider Foundation, volunteers documented a 150 percent increase in discarded vapes collected during beach cleanups between 2021 and 2024. Each device contains approximately 0.15 grams of lithium, and with millions of units discarded annually, the industry is effectively throwing away tons of critical battery materials that could be reclaimed.

A study published in Joule by researchers at the University of Oxford and University College London found that the lithium-ion batteries in disposable electronic cigarettes, while discarded after single use, retain the capacity for hundreds of additional charge cycles. Yet only 17 percent of vapers properly recycle their devices through appropriate channels, and just 8 percent of young adult vapers send used devices to recycling facilities. The result is millions of rechargeable batteries—containing scarce, valuable lithium—entering landfills, where they pose fire hazards. Research by Material Focus documented a 71 percent increase in battery fires in the UK waste stream in 2024, with more than 1,200 fires recorded, many caused by discarded lithium batteries from disposable vapes.

Beyond the environmental benefits, the Vape Synth project exemplifies the educational potential of "circuit bending"—the artistic practice of modifying consumer electronics to create new musical instruments. This approach, pioneered by artists like Qubais Reed Ghazala in the 1960s, has evolved into a legitimate pedagogical tool for teaching electronics, acoustics, and creative coding.

The movement has gained significant traction in maker spaces and educational institutions. In Urbana, Illinois, Colten Jackson founded the "Electronic Waste Orchestra" after reading Hackaday articles about converting old hard drives into synthesizers. His initiatives, which include bi-monthly meetups and summer camps for children, demonstrate how e-waste upcycling can serve as an entry point for STEAM education.

"Circuit bending is the repurposing of old toys, consumer electronics, digital synthesizers, drum machines and virtually any low voltage device for the sake of sonic exploration," explains documentation from ProAudioFiles, highlighting how this practice transforms obsolete technology into creative tools.

The Vape Synth project arrives at a critical moment for both environmental policy and maker culture. Several jurisdictions, including the United Kingdom and various U.S. states, are considering or implementing bans on disposable vapes due to their environmental impact. Vermont, California, and New York have introduced legislation restricting single-use vaping products, while the European Union's Waste Electrical and Electronic Equipment (WEEE) directives increasingly scrutinize these devices.

Yet as policymakers debate regulatory solutions, grassroots maker communities are already demonstrating practical alternatives. The Paper Bag collective has published open-source documentation enabling others to replicate their design, fostering a distributed movement of e-waste transformation. Hackster.io, a leading platform for hardware projects, featured detailed build instructions, while discussion forums on Reddit's r/CircuitBending and r/upcycling communities show growing interest in vape component repurposing.

The broader implications extend beyond vaping devices. The maker philosophy—examining everyday objects for their hidden potential, questioning designed obsolescence, and sharing knowledge openly—represents a cultural shift toward viewing waste as resources awaiting creative transformation. When a $15 disposable vape containing a rechargeable battery, pressure sensor, and USB charging circuit can be converted into a musical instrument, it exposes the absurdity of single-use electronics design.

Why It Matters

This project demonstrates that environmental solutions need not be purely technological or regulatory—they can be deeply creative and educational. By transforming toxic waste into art, these hackers challenge us to reconsider what we discard and inspire a generation to see possibility where others see trash. It represents the best of maker culture: open-source knowledge sharing, environmental consciousness, and the creative repurposing of consumer technology.

Background

Circuit bending emerged from the experimental music scene of the 1960s, when artists began modifying electronic toys and keyboards to produce unexpected sounds. The practice gained mainstream recognition through artists like Reed Ghazala, who discovered that short-circuiting battery-powered toys created unpredictable but musically interesting effects. Today, circuit bending functions as both an artistic practice and an accessible entry point into electronics education, requiring minimal tools—often just a soldering iron and basic components—to transform everyday devices into unique instruments.

What's Next

As environmental concerns mount and disposable electronics face increasing regulatory scrutiny, projects like the Vape Synth may influence both consumer behavior and product design. Maker communities continue expanding documentation for various vape repurposing projects, from basic battery reclamation to sophisticated microcontroller applications. Environmental organizations are increasingly collaborating with maker spaces to develop educational programs around e-waste upcycling, potentially creating new pathways for STEAM education while addressing mounting electronic waste concerns.
