There's a ridiculous amount of tech in a disposable vape

For these devices the microcontroller needs to be super cheap. Microcontrollers like the Puya PY32 Series (e.g., PY32C642, PY32F002/F030) can cost in the $0.02 - $0.05 range for the kind of many-million volumes applicable for disposable vapes. These are 32-bit ARM Cortex M0 MCUs, running at a 24 MHz clock or similar, some with 24 KB of ROM and maybe 3 KB of RAM!

To put into context: this is 3x the ROM/RAM of the ZX81 home computer of the early 1980s. The ARM M0 processor does full 32-bit multiplication in hardware, versus the Z80 that doesn't even offer an 8-bit multiply instruction. If we look at some BASIC code doing soft-float computation, as was most common at the time, the execution speed is about 3 orders of magnitude faster, while the cost of the processor is 2 - 3 orders of magnitudes less. What an amazing time we live in!

Many countries have deposits for single use bottles/cans but an electronic device with a lipo battery is seen as perfectly fine to throw away.

These things should have 100 times the deposit amount of a can of soda with mandatory requirements for retailers to take the 'empties' back.

Our whole current civilization could be construed as advanced alien tech servicing a humongous tribe of moronic apes. The fact that one fifth of the internet is dedicated to porn just speaks for itself. Just thinking about all the tech involved, from the capturing of footage using highly sophisticated camera, to the transmission over kilometers of fiber optics, to the stokage into redundant and consistent databases backed by highly optimized hardware and brilliantly engineered file format, to the distribution to your phone device, which is literally a personal computer that fits in your palm.. all of that just to show porn to satisfy your monkey brain.

It seems almost absurd to what length humanity has gone just to satisfy it's primitive needs.

As a smoker who transitioned to vaping, I see immense health benefits.

My home country (India), and others (Singapore, others?) have outright banned all electronic cigarettes which is a regulation I hate. I acknowledge that vapes reduce barriers to entry to kids. This is partly solvable in countries with strong governance.

But disposables? Ban that shit

I've just started a Salvage Pile in my workshop. Laser printer with fax modem was the first for excision and harvest. I could feel the addiction take hold before the last of the plastic shell was tossed into the refuse bin. The stepper motors alone!

I have a huge old microwave on the blocks next. After that a series of small odd ball electronic toys and a few early LED bulbs. If I ever come across a vape, I'm sure it'll make its way on to the shelf.

I still think the next evolution of these vapes is for a Tamagotchi-esque device to get built into them and to have the pet grow when you inhale through it. You're already walking around with enough tech - why not gamify it more?

Some of the COVID test kits that were popular a few years ago(!) were even more complex.

Currently working on a method to recycle / repurpose the li-ion cells obtained from the disposable vapes, trying to scale up the recycling effort by releasing products to fund the manpower required to breakdown and sort the vape components . Getting close to releasing the first 100 demo models of the product for stress testing in the wild. Currently based in the greater Seattle area and here is a link to my site if anyone wanted to know more: https://2ndchancemnd.com/

I remember the good old days when a "vape" was just a sturdy housing for a rechargable battery, some heating wire, cotton and juice. The power was determined by the resistance of the coils you built. Those things would last forever.

A few years ago I saw a vape with a full display that played a pac man clone aside from the state and settings, and now I have a drawer of random vape screens and components that I swear i'm going to use one of these years.

In 40 more years I wonder what the equivalent of "same specs in a disposable vape as home computer from 80's" will be

This is a really interesting topic but not a thorough article imo. I don't really understand how the 6 flavours come about, what the sucking positions the author mentions are etc. Would love it if you go into more detail. Also, now I have a very strong urge to buy one of these things and take it apart. Inspirational!

It feels so odd to think that the human which is self poisoning with an electronic device that will be neglectedly thrown on public area is not that different from the one who would diligently bring it to a trash, even curiosity didn't jump in to enjoy analysis of the device.

Also, it's fun to imagine someone building whole racks of these (e.g. recycled ones) for a computation farm. Or a cheap home server, whatever.

After-school tech club idea: instead of just handing kids an Arduino, tell them to get their purloined vapes out of their pockets and hack 'em till you get JTAG or semixosting working.

And they have little displays on them, OLED displays which show the battery life and remaining fluid.

Doesn't look like SMD was great. This looks like lowest cost has gone back to .. rows of people with a soldering iron patching the cheapest possible flow process.

Put it this way, from engineering and technology perpective vape is equivalent to generalization of smoking tools (cigarette, pipe, etc). Naturally it's a very complex as a system and no small feat because you are going to generalize relativity and AI, for examples general relativity and AGI, respectively.

I'm amazed there isn't more of an outcry against these things. I'm not an environmental activist, but even I'd feel wrong just throwing something like that away.

The ESP32 (with Bluetooth and WiFi) is like $5 on AMZN. Which is probably sub-$2 in any meaningful quantity in Shenzhen. We've been living, at least until the tariffs, in a StarTrek like world where whatever we want is available from Shenzhen for a ridiculously low price (which in many respects is better than "free" because "free" brings with it its own humongous problems).

These products are targeted towards high school teens and middle schoolers, carry a number of serious health risks, and anyone involved in making them can rot in hell.

Is this actually disposable if it has the rechargeable battery and display? Or is it maybe like a lighter that technically can be refilled but nobody ever does?

It's so curious why these things are addictive. Before I tried a vape (it was called an e-cigarette back then) I thought the addictive thing about cigarettes is the nicotine. That's part of it, but a huge part (possibly even bigger) is just the sensation of sucking in smoke/vapour from a little stick and exhaling it. Is it similar to sucking on a mother's teat or something? It really seems to satisfy in a way nothing else does.

In the UK truly disposable vapes are banned, thankfully, but I do wonder if it's now just "technically refillable" ones that people use one time. They should be taxed to the eyeballs to encourage reuse if so.

It's not rediculous if you look at this through a modern lens. In reality this tech is cheap. Trying to keep it around is hoarder mentality. You are stockpiling garbage which can be cheaply replaced.
