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.

[–] Pollo_Jack@lemmy.world 13 points 13 hours ago (2 children)

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.

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?

Not sure what they're implying about being forced to sell non refillable vapes. I bought a Centaurus kit (refillable) two years ago and they're still selling. Though the same brand also has lines of disposables...

In reality the people buying disposables don't want to deal with the hassle that is e-juice (and changing coils). But the modern refillables are pretty good at not leaking every time you look at them wrong, though in my experience the big ones still don't like being upside down.

...commodified cannabis is garbage and distillate is hotdog water, though

Right after porting Doom.

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

Bigger opportunity would be banning this shit.

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

[–] pirat@lemmy.world 7 points 12 hours ago* (last edited 12 hours 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.

Next up, turning these into AI web scraper bots!

"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.

[–] LovableSidekick@lemmy.world 4 points 11 hours ago* (last edited 11 hours ago) (2 children)

Yes, where "process" means measuring instantaneous changes in airflow as the user inhales (or doesn't), and regulating a heating coil accordingly by running actual program code - which requires a controller to run it and memory to store it in. I mean when you click "Reply" on this page all it has to do is process one button, but that involves a lot.

[–] kevinsky@feddit.nl 1 points 15 minutes ago* (last edited 14 minutes ago)

All that logic is still a choice though. You could also just instruct the user to not press the button unless they're inhaling and just actually have it be an on and of button. That's how vapes used to work. Worst thing that could happen there is that you burn the wick, which is only a problem because it's not serviceable.

Some of them have games like snake you can play in class on them. I mean that's what I assume its for, any adult would use their phone.

[–] Melobol@lemmy.ml 2 points 11 hours ago* (last edited 11 hours ago) (1 children)

There were couple series of: full lcd screen, bt connected to smartphone for notifications and a speaker versions. Plus the rechargeable battery and usb c charging port (obviously).
It was selling about 35 bucks.
Forgot the game one: had controller buttons and 3 games: pacman, tetris and a lying shooter inbuilt. With full lcd and speaker. (Thus wasnt bt connected tho) Price was similar.

[–] Sylvartas@lemmy.dbzer0.com 1 points 1 hour ago

Forgot the phone one too. Or was it a phone "case" ?

[–] Aceticon@lemmy.dbzer0.com 20 points 21 hours ago* (last edited 21 hours ago) (2 children)

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.

[–] merdaverse@lemmy.zip 6 points 14 hours ago* (last edited 14 hours ago)

It's crazy to think that this is basically more powerful than the Apollo Guidance Computer that got people onto the moon. It costs 3 cents, and we use it for shit like this and then throw it away. What spectacular waste.

[–] KairuByte@lemmy.dbzer0.com 11 points 20 hours 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.

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.

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.
