This further illustrates how absolutely crazy it is to produce these devices for a single use and then just throw them away, not even making sure they can be recycled properly. It's complete madness. I hope they'll be banned soon, I think the EU is working on it.

[–] terranoid@lemmy.cafe 74 points 1 week ago (10 children)

They should absolutely ban disposable but as long as they're smart about it and don't try and make it a general vape ban. Anything with a microcontroller and OLED display should need regulation to be "disposable". So fucking wasteful.

Vapes can and have always been something you can pop a battery and cartridge and custom juice in. There's zero reason to make it disposable. Make the coil/cotton/juice cartridge disposable... Like a juul was last I checked? That's reasonable.

And then next regulate how much nicotine can be in per ml. 60mg/ml is fucking insane. That is heart issue level of nicotine. I got buzzed off 12 mg/ml, used 3 or 6mg/ml regularly, and quit at 1.5mg/ml. There's no fucking reason other than harm and addiction to provide 60mg/ml.

https://www.consilium.europa.eu/en/press/press-releases/2023/07/10/council-adopts-new-regulation-on-batteries-and-waste-batteries/

The regulation provides that by 2027 portable batteries incorporated into appliances should be removable and replaceable by the end-user

Coming soon...

Disposable vapes are already forbidden, at least in France, idk if it is union wide.

But yeah, those things make no sense. The only thing with a battery that should be disposable would be fire alarm. Not because of the battery, but because the main sensor has a 10 years lifespan due to its natural deterioration.

"it was actually a PY32F002B, powered by a 24 MHz Arm Cortex M0+ processor. The chip also carried 24KB of flash storage and 3KB of static RAM"

To process a single button.

[–] stardreamer@lemmy.blahaj.zone 49 points 1 week ago* (last edited 1 week ago) (1 children)

Because an existing SoC at scale is cheaper than a custom ASIC.

You see this all the time, custom keyboard running ARM+Linux, SmartNICs using RISC-V cores/FPGAs instead of ASIC accelerators. Even Microsoft refuses to commit to ASICs for network processing in their DCs and use FPGAs instead.

[–] wewbull@feddit.uk 31 points 1 week ago (15 children)

A vape is a battery connected to a button connected to a heating coil. You might want a single transistor. You don't need a software platform.

[–] Croquette@sh.itjust.works 24 points 1 week ago

There is also a battery management system as well.

M0 processors are dirt cheap, especially in bulk.

They probably have a BMS library that takes a few Kb of flash.

The time it would take to make the design cost effective wouldn't be worth it.

Slap a less than a dollar mcu and be done with it.

[–] I_Has_A_Hat@lemmy.world 23 points 1 week ago (2 children)

Sure, if you weren't competing with every other vape out there that has things like variable voltage settings (at least 3), a pre-heat feature, the ability to turn on/off with 5 presses, or to turn off automatically after 5-10 minutes without use, a low battery indicator, a charging indicator, a broken coil indicator...

Hmm, seems like you need a lot more than a battery, heating coil, button, and single transistor.

I used to be into vaping and a big mechanical vape fan. I still have all of my old mech vapes! Those were what you’re thinking of—a button, a conducive body, and a coil or two mounted to a post. You pop an 18650 in, no transistor or resistors needed. You adjust your wattage by changing the way you wrap your coils, and your wire gauge. Generally I’d like to run around .2 ohms, which pushes about 18-20 amps out of the 18650s.

These are NOT devices you want in the hands of regular people lawl. I’ve had friends in years past love how my setup was and get similar vapes for themselves. I’ve seen a burned-down backpack (RIP, all of his adderall XR), a table almost catch fire, and burnt carpet. No explosions because I told people “don’t get one of these, but if you’re not going to listen to me, for the love of glob make sure it’s vented.”

Anyway, yeah no way anyone should have these except electronics enthusiasts. Even with locking rings, they can just start firing if the person using it isn’t super careful. Nice batteries rated for 30a pulse are 2USD more than the garbage batteries that love to vent or explode.

You add in a transistor, that’s not gonna do anything. You add in a couple more things for protection and your cost is higher than it would have been by getting one of the chips in OP’s article, and you don’t have a nice interface for adjusting wattage and checking battery level and charging via USB and all that fun shit.

Well the PY32F002B (costing a few cents) even though it has a 32-bit (entry level) ARM core @ 24MHz is literally cheaper than older and less powerful microcontrollers.

Granted, if you don't do anything else than react to a push button it's still cheaper to use discrete electronic components than a microcontroller, but given that this device has a LiPo battery (meaning there's battery control involved) and judging by the picture a USB-C connector, there's probably a bit more digital logic in it, by which point a 3 cent microcontroller plus a cheap SMD crystal and some caps is cheaper than using discrete components.

The domain of embedded systems has evolved to the point that it's the best option for almost everything in consumer electronics, mainly because at the lower end there are so many stupidly cheap and easy to use choices were you don't run an OS in it but instead just a single block of single-threaded code directly on the bare metal accessing registers directly.

[–] KairuByte@lemmy.dbzer0.com 11 points 1 week ago (1 children)

Temperature control, likely something to keep track of how much is left in the device, and I’m betting I’m forgetting something.

I doubt discreet electronics can cut it at that point.

It's so you can have a spinny animation when you hit the button.

Reusing them, even in small experimental projects, underscores a broader sustainability opportunity.

Bigger opportunity would be banning this shit.

why does a glorified heater connected to a battery need any silicon attached to it?

[–] Kolanaki@pawb.social 83 points 1 week ago* (last edited 1 week ago) (22 children)

To control the amount of voltage used in making the heat and not immediately burst into flames, for one.

[–] stoy@lemmy.zip 68 points 1 week ago (1 children)

It is interesting to see old tech having clever solutions for stuff like this, these days the answer is 98% of the time is to slap a CPU on it.

It's boring!

[–] ImgurRefugee114@reddthat.com 27 points 1 week ago (7 children)

Wait til you hear about all the different technologies we use to generate electricity

[–] stoy@lemmy.zip 28 points 1 week ago (2 children)

99% spinning a generator and 1% direct solar panels

[–] Valmond@lemmy.dbzer0.com 10 points 1 week ago (3 children)

Hey, hasn't that panel number been going up lately?

It's probably cheaper and simpler to modify (say you suddenly want it to turn on when you click 3 times) to use a 0.1€ chip than to figure out how to do it and build it with discrete components.

20 years ago I was all "computer (chips) can do everything! We can use them everywhere! Replaceable, reprogrammable, fantastic!"

And no one cared.

Now they are everywhere and it's just a fucking mess 😔

Maybe 20 years from now the EU will have forced standards onto everything and you can (again) fix your dishwasher (and start it from work!!1!).

In my mind, nothing with a circuit board is disposable. Pains me to see it.

[–] kevinsky@feddit.nl 25 points 1 week ago (1 children)

There also has already been someone that made a home battery from batteries harvested from disposable vapes.

It is absolutely insane that these "disposable" vapes are legal.

I don't get those pieces of crap. There were these fancy electric cigarettes years ago, using those 3.7V rechargeable batteries. Custom designs (saw lightsaber designs), custom liquids, repairable, no e-waste. What is wrong with people to use those crapsticks? And why do those dumbnuts don't get that these things are e-waste not residual waste?

As a manufacturer/seller of disposable vapes, literally everyone wants refillable tanks.

Obviously the customer does too but we're vertically integrated. We grow, extract, flavor, fill, and sell. Managing the logistics from China sucks and requires a decent amount of overbuying to ensure we have a steady stream. You never know when some orange retard will close up the border to x country that makes your stuff.

I'd love to just have a CoA of the distillate, flavor mixer like a coke machine, and a fill nozzle for the customer to hand to the cashier to fill.

[–] kevinsky@feddit.nl 10 points 1 week ago* (last edited 1 week ago) (2 children)

What happened to vaping?

I specifically remember refillable vaping was exactly what you had when you vaped. You had the battery unit or a "mod" as it was called, on top of that you screwed a tank that had the coils, cotton and liquid, all that shit could be individually replaced and everybody had their own frankensteins combination of mod tank and other peripherals they liked to use.

Why did that stop being a thing in favor of these absurdly wasteful disposable pens?

24 MHz Arm Cortex M0+ processor. The chip also carried 24KB of flash storage and 3KB of static RAM.

... a 10y old phone can barely load Google, and this is about 100x slower.

Wild that you can serve anything with that hardware. Granted, static websites are basically just sending files over the wire.

[–] BCsven@lemmy.ca 17 points 1 week ago

The 10 year old phone OS probably is slowing all of that. If they flashed phone as a dedicated webserver it would probably be fine

[–] disorderly@lemmy.world 12 points 1 week ago (1 children)

The webpage he hosted was a copy of his own blog post explaining the hack. It just about fit into the 20KB of available flash storage.

We can infer that on every request, the whole static page needs to be spooled out of flash onto RAM (in chunks no larger than 3k), then sent out over Ethernet.

That's an awful lot of work for the chip. I'm not surprised at all that it errors out under heavy load. The request queue probably grows until it collides with the buffer that bucket brigades the web page to the network.

I'm afraid to look up what optimizations were necessary to get that level of performance. It's damned impressive work.

Ok here's my billion dollar idea: vapes that already are web servers!

[–] pirat@lemmy.world 9 points 1 week ago* (last edited 1 week ago) (1 children)

Ok here's my trillion dollar idea:

SmartVape CloudBar. A range of premium smart home vaping devices that connect to (and depend on) the cloud so you can smartvape remotely (e.g. in the bed, on the job, or even when travelling).

Vaping, even locally, always works, unless your subscription has expired, there's no internet connection available, or any of the necessary cloud service are down.
