2022 Hackaday Prize: Disposable Vape Pens Turned Project Parts

If you’ve ever looked at a “disposable” gadget and thought, “That’s not disposable… that’s just a parts kit with marketing”,
you’re in excellent company. In 2022, the Hackaday Prize leaned hard into ideas like sustainability, resiliency, and circularityand
one of the most perfectly on-theme stories came from an unlikely place: disposable vape pens.

These little devices are engineered to be cheap, compact, and powerful (at least for a short while). They’re also engineered to be
thrown away. That’s the problem. But it’s also the twist: inside many of them are genuinely useful componentsbatteries, charge boards,
sensors, LEDs, wiring, and enclosuresthat can be repurposed into real projects instead of becoming e-waste confetti.

Why the 2022 Hackaday Prize Theme Made This Story Inevitable

The 2022 Hackaday Prize wasn’t about building the fanciest gadget in a vacuum. It challenged makers to build (or rebuild) with the
planet in mindprojects that reflect sustainability, resiliency, and circularity. In plain English: don’t just invent new stuff; get
smarter about the stuff that already exists, and keep useful materials in circulation as long as possible.

That’s why “Disposable Vape Pens Turned Project Parts” landed like a perfectly timed punchline. A disposable product with a rechargeable
lithium battery is a strange kind of irony: it’s like putting racing tires on a shopping cart. The engineering is real, the lifespan is
not. Turning those parts into prototypes, tools, or learning platforms is a very Hackaday solution to a very modern mess.

The Disposable Vape Problem: Tiny Gadget, Big Trash Footprint

Disposable e-cigarettes create a complicated waste stream. They’re small, easy to toss, and often contain a lithium-ion battery plus
residual nicotine and other materials. Communities and institutions (like schools) can face stricter disposal requirements than
households, and safe disposal can become expensive and logistically messy. Meanwhile, the devices pile upphysically in bins and
figuratively as a policy headache.

Then there’s the fire risk. Lithium-ion batteries don’t appreciate being crushed, punctured, or compacted in trucks and facilities.
This is why safety guidance typically says: don’t put lithium-ion batteries (or devices containing them) in household trash or
recycling bins; use proper collection points and take steps like taping terminals or bagging batteries to reduce short-circuit risk.
It’s not “paranoid,” it’s “please don’t set the garbage truck on fire.”

What’s Actually Inside a Disposable Vape Pen?

The exact internals vary by brand and generation, but the “anatomy” is surprisingly consistent. Many disposable vapes are essentially a
compact power system (battery + charging/protection + switching), a heating element (coil), an airflow or pressure trigger, and a
plastic/aluminum shell that’s already the right shape to be… basically anything cylindrical and handheld.

A quick anatomy checklist

• Lithium battery (often a flat pouch cell, sized to fit the enclosure)
• Charging and protection circuitry (sometimes with USB-C or micro-USB on “rechargeable disposables”)
• Airflow/pressure sensor or switch (the “it knows you’re inhaling” part)
• Status LED (sometimes multiple colors or a tiny light pipe)
• Heating coil + wick assembly (not always reusable, but educational and occasionally repurposable)
• Wiring, connectors, and contact springs
• Enclosure (shockingly useful as a ready-made case)

The big surprise for many makers is how “project-ready” the packaging already is. No screws, minimal hardware, lots of snaps and tape,
and a form factor that’s basically begging to become a flashlight, sensor tube, mini power bank, or pocket tool.

From Vape to “Parts Donor”: The Hackaday Prize Angle

In the Hackaday Prize story that kicked this off, maker Dimitar explored how to reuse as much of a vape pen as possible,
framing it as an underappreciated source of parts. The guiding idea wasn’t “yay, free stuff,” but “this stuff shouldn’t be wasted,”
especially when it contains batteries and electronics that still have a useful second life.

Dimitar’s project treated vape pens like the next “Altoids tin” of hackinga common, oddly standardized enclosure that hobbyists can
turn into dozens of small builds. He floated and developed ideas like an electric screwdriver, an LED flashlight,
a small battery bank, a sensor pod, and even experiments with the heating wire for a foam cutter.

Project Parts You Can Reuse (And What They’re Good For)

1) The battery: tiny power, big value

The lithium battery is the headline act. It’s compact, rechargeable, and capable of delivering meaningful currentexactly why it’s used
in the first place. In maker terms, it’s a power source for prototypes that would otherwise burn through coin cells or require a bulkier
pack.

A classic example from the broader Hackaday universe: using an e-cig battery to power wearable electronics like LED-adorned sunglasses,
replacing a less convenient battery format. That’s the spirittake a battery that was destined for the landfill and give it another job.

Reality check: batteries are also the part that can hurt you (or your workshop) if mishandled. Reuse only if you can
verify basic safety: no swelling, no punctures, no corrosion, no mystery heat events. If anything looks sketchy, treat it as a disposal
problem, not a salvage win.

2) Charging and protection circuitry: the “boring” part that makes builds practical

Rechargeable disposables sometimes include a USB port and basic charge management. Even when the board is tiny and barebones, it can
teach (and sometimes provide) the essentials: charging a single lithium cell, basic protection, and a convenient place to plug in power.
If you’ve ever built a prototype that worked great until you had to charge it, you already understand why this matters.

3) Airflow/pressure sensor: a free input device hiding in plain sight

Many vapes activate when you inhale. That means there’s usually a sensor or switch that detects airflow/pressure change. For hackers,
this is a ready-made triggeran input you can repurpose for touchless activation, breath-controlled interfaces, “blow to start” toys,
or simple environmental experiments (with appropriate filtering and safety).

4) LEDs and light pipes: instant UI for your prototype

A single LED might not sound exciting until you remember how often prototypes need “some kind of indicator.” Power, charging, error,
modeboom. The enclosure already has a window or diffuser, the LED is already aligned, and suddenly your project looks less like a
breadboard accident and more like a product.

5) The enclosure: the most underrated “part”

Cases are hard. They’re time-consuming, fiddly, and often the reason a fun prototype never leaves the bench. Vape enclosures are
already pocket-friendly, standardized enough to be predictable, and common enough to be available in quantity. That’s why Dimitar’s
“next Altoids tin” comment lands: it’s not just about componentsit’s about having a ready-to-go form factor.

Five Realistic Project Ideas (Inspired by 2022 Hackaday Prize Thinking)

1) Electric screwdriver or mini driver handle

This was one of Dimitar’s earliest ideas: a lightweight handheld tool that benefits from a small internal battery and a compact body.
Add directional controls, a motor driver, and you’ve got a real workshop helperespecially for quick jobs.

2) LED flashlight or work light

The enclosure shape is already perfect for a flashlight. Combine the battery, a driver circuit, and a decent LED, and you have a build
that feels “complete” fast. Bonus points if you reuse the existing charging port and status light.

3) Emergency micro power bank

A single cell won’t replace a big commercial battery pack, but it can absolutely save you in a pinch. With the right power conversion
and protection, you can create a tiny “just enough” charger for low-power devices or short top-ups.

4) Sensor pod (environment, motion, GPS, or data logging)

The tube-shaped case is a natural home for a small microcontroller board plus sensorstemperature/humidity, motion, magnetometer, or
a compact GPS module. It’s a nice fit for experiments in field logging, bicycle tracking, or environmental monitoring.

5) Hot-wire foam cutter experiments (with caution)

Heating elements are educational: they teach power, resistance, and thermal behavior fast. Some makers explore whether parts of the
heating assembly can be adapted for small cutting or heating tasks. This is also where the “be careful” signs multiply: high currents,
heat, and unknown residues are not a casual combo.

Safety, Ethics, and “Please Don’t Make This Weird”

Reuse is awesome. Unsafe reuse is not. Disposable vapes can contain nicotine residue and unknown fluids; batteries can be damaged;
circuits can be flimsy; and disassembly methods vary widely. If you’re salvaging from used devices, prioritize basic precautions:
gloves, ventilation, careful handling of any residue, and safe storage for batteries.

Also: don’t build a “parts pipeline” that encourages more disposable consumption. The point is to recover value from waste already in
circulation, not to create demand for more. If you want repeatable parts for teaching or prototyping, consider sourcing from proper
e-waste streams, take-back programs, or devices that are already being discarded.

Why This Story Still Matters After 2022

The Hackaday Prize is a competition, but it’s also a cultural signal: the maker community cares about how things are made, how they
fail, and what happens after the novelty wears off. Disposable vapes are a modern “design contradiction”highly engineered internals
packaged for short-term use. Repurposing those internals is a small, practical act of circularity.

And it scales in an interesting way. One salvaged battery won’t “solve e-waste.” But a thousand salvaged batteries used in classrooms,
prototypes, and community projects is a thousand batteries not crushed in a waste stream. Combine that with better disposal habits,
smarter regulations, and manufacturer responsibility, and you get a real shiftnot just a clever hack.

Hands-On Experiences: What It’s Like Turning Disposable Vapes Into Project Parts (About )

The first “experience” most makers have with vape reuse is surprisespecifically, surprise at how much engineering is hiding in a device
that was never meant to be loved, repaired, or even remembered. You crack one open expecting a sad little battery and maybe an LED, and
you end up staring at a compact system: a cell, a control board, a sensor, wiring routed like someone cared, and plastic parts that snap
together with infuriating confidence. It’s the emotional equivalent of finding a gourmet truffle in a fast-food wrapper.

Then comes the second experience: variation. Two devices that look identical on the outside may behave like totally different species on
the inside. One has a USB-C port and a tidy little board; another is a minimalist “one-and-done” design with fewer reusable parts. Some
batteries are labeled; others are anonymous pouches that require extra caution. Some airflow triggers behave like a clean digital switch;
others are more analog and finicky. This variety is annoying if you want consistent partsbut fantastic if your goal is learning. It’s
reverse engineering in snack-sized portions.

The third experience is a crash course in battery respect. Salvaged lithium cells can be incredibly useful, but they demand better
habits than “toss it in a drawer.” Makers quickly learn to isolate terminals, store cells safely, and treat any swelling or damage as an
immediate “nope.” You also learn that battery management isn’t optional if you want a project you can hand to someone without sweating.
In a weird way, these tiny devices teach big lessons: safety is not a vibe; it’s a checklist.

Next comes the “enclosure epiphany.” Many projects die at the case stageeverything works, but it looks like a science fair prototype
from a parallel universe. Vape bodies are already pocketable, ergonomic, and oddly durable. You can mount a small microcontroller, add a
sensor window, reuse the indicator LED, and suddenly your project looks intentional. That’s a huge motivation boost. It’s easier to keep
iterating when the build feels like an object, not a tangle.

Finally, there’s the community experience: once you start thinking this way, you see parts donors everywhere. Old gadgets become
component libraries. Packaging becomes enclosure stock. And the maker mindset shifts from “What should I buy?” to “What do I already
have that can do the job?” That’s the real win of the 2022 Hackaday Prize vibeturning sustainability from an abstract slogan into a
practical design habit. The joke is that disposable vapes were never meant to be educational. The punchline is that they accidentally
became a class in circular engineering.

Conclusion

“Disposable Vape Pens Turned Project Parts” is a perfect 2022 Hackaday Prize story because it’s equal parts practical, mischievous, and
principled. It acknowledges reality (these devices exist, and they’re piling up) and responds with a builder’s logic: salvage what’s
useful, learn how it works, and keep materials in circulation longer than the manufacturer intended.

If you take one thing from this: treat vape pens like hazardous e-waste first and a parts donor second. Salvage safely, store batteries
responsibly, and dispose of what you can’t use through proper channels. The goal isn’t to glorify the productit’s to reduce harm and
extract value from a waste stream that shouldn’t exist at this scale.
