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.

As someone who vapes quite a bit, I would genuinely love to see this. Disposables are an absolute shitshow and never should have existed in the first place.

Seriously. I struggle to fathom how running out for disposables is even slightly more convenient than refilling a proper tank every so often and replacing the coil. It tastes better, lasts longer and makes much less waste.
- new_world_odor@lemmy.worldEnglish4 hours
I think it’s the marketing of it. A decent amount of people I’ve talked to genuinely don’t know that there’s a reusable option. This also changed when the tobacco industry got involved. Vaping used to have more of a culture of cessation. It was talked about how you could transition from cigs at a higher nicotine level, then bring it down until you’re vaping zero nic, then quit that. I barely hear anyone talk about the quitting pipeline anymore. I don’t think it’s an accident, I think it’s intentional.
Edit: I also think it’s the fact that you only have to buy one thing, and the 3 things (device, coils, juice) aren’t available in every gas station like disposables are. And the user experience - open the box and it starts right up, no refills, all it needs is a charge once in a while. People are really fucking lazy, by nature. But the cost of all those conveniences is indebted tenfold upon the environment, as destruction and waste.

- Aceticon@lemmy.dbzer0.comEnglish9 hours
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.
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.
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.

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.
- I_Has_A_Hat@lemmy.worldEnglish10 hours
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.
- 9 hours
With the major caveat that dispos dont offer more than 2 of those features at best. Almost all those features you specify are on reusable devices. There are going to be some that do have those additional features, but at a price point that makes them nearly as or more costly than a reusable device.
The only IC you need for a disposable really, is a BMS, and a temp sensor (technically a timer so it also doesnt over draw, but timer ICs are built into everything) so it doesn’t willfully light itself on fire in unusual circumstances.
All that to say: there is effectively 0 difference between most disposables released today and reusables, with the sole exception that you cant refill or recharge them. There should be no device with a battery deliberately intended to be thrown away, for anything, save for medical uses.

You’re sooooo right, check my response to that guy. I was into vaping years ago and loved mechanical vaoes, which were legit just a battery, heating coil mounted to a platform, button, and conductive tube. Super simple devices, so easy!
Except they’re INSANELY DANGEROUS! I loved them but I’ve had friends treat them carelessly and they WILL start on fire or even explode if not vented. You need a thorough understanding of Ohm’s law, batteries’ amperage limits, how to rewrap batteries with nicks in the wrap, and to never leave them unattended even with manual locking rings.
The person you replied to mentions adding a transistor which would do nothing. Add some more bits and just like you said, you’re competing with fully functional vapes with all those features and they’re cheap as hell. The chips cost nearly nothing, so that’s the route they go. Those vapes aren’t impervious to blowing up, but they’re much safer than simple mechanical vapes.
- Rai@lemmy.dbzer0.comEnglish9 hours
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.

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

Digipart is showing me price for PY32F002B with a minimum purchase of 5000 as less that $0.10 (not the factory price, just the cheapest store).
The price for the cheapest NE555 (random manufacturer implementation of a 555) variant in Digipart is $0.13
(Granted, you also need at least a crystal and 2 caps, plus 1 power filtering cap per power line for the microcontroller, but those are all cheap)
It’s ridiculous how modern microcontrollers are so stupidly cheap that even though they can run a lot more digital logic (in the form of software running in them) they almost always beat using older and much simpler digital parts even for something as simple as this.
Even microprocessors are getting stupidly cheap: somebody recently pointed me out the Allwinner F1C100s, which is about the smallest microprocessor that can run Linux, and it costs $2 in bulk to the point that some embedded engineer has made a business card with one running Linux which he just gives away.

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.

- Aceticon@lemmy.dbzer0.comEnglish6 hours
Yeah, it doesn’t make much since if you think in terms of how many transistors are needed to implement each of them as the microcontroller probably uses hundreds of thousands more transistors than a 555.
That said, given reasonably recent processes die size for both are probably pretty close (I reckon most of the size of a modern 555 die would be the points to place the wires to the package) and with pretty similar yields (pretty close to 100%)
I wouldn’t be surprised if the reason has something to do with economies of scale since a cheap microcontroller can pretty much be used for the same things as a 555 and a whole lot more than that, so it makes sense more of the former are manufactured than of the latter, plus I bet the process generation used in making the microcontroller is probably more recent and hence one where there are more fabs operating. This latter reason would also explain why this more recent 32-bit microcontroller is actually cheaper than older 8-bit ones with less built-in memory and fewer peripherals (such as the ATTiny ones).

When production volume and turnaround time is the only things that matter in this shovel waste crap, “wasting” silicon is less expensive financially than building out the optimal solution.
- Aceticon@lemmy.dbzer0.comEnglish8 hours
Designing a board to run a microcontroller like that is actually pretty simple.
I’ve done it for fun with a couple similar microcontrollers, and whilst I’m an EE by training I don’t do it professionally plus my training is from before embedded system, so I count as a Junior EE for that.
I’m pretty sure that even a freshly graduate Chinese EE can even on their own figure out the general recipe for integrating something this (following the datasheet, add crystal + load caps, plus about 1 caps each power pin for power filtering plus 1 global power filtering cap, plus possibly a pull-down/up resistor on the RESET pin) in a week or two and then for subsequent projects it will be feasible to do it in a few days.
Really, there’s other shit in there (say, battery management) that’s more work to figure out than how to add and place the parts for an entry level ARM microcontroller to work.
my guess would be it’s a parts commonality thing, it’s not hard to make it the old way, there are datasheets for it too. sure you could probably make tiny and cheaper (30x10mm? maybe smaller) analog board with two chips and mosfet working as pwm controller and current limiter, but it’ll have different passives for different battery sizes and heater powers. or you could make one design with optional usb port that you might just not solder on, and depending on model you just put different firmware inside
- Hitchie_Rawtin@lemmy.worldEnglish14 hours
The old way is actually the analog style you’ve mentioned, but that was the very early days of ecigs well before they became mass market, the cottage industry modding scene had no hope of creating sophisticated microcontrollers and the charger wasn’t even USB, it was a DC jack & plug. Lavatube was the first time we had that kind of microcontroller regulation & then the DNA15 and DNA20 came out, got cloned by China and that changed the game forever.
The problem with the older way is consumers understand watts alone as a relatively consistent measurement of power much better than they would the relation between voltage, resistance & current draw. They didn’t want to learn Ohm 's Law back then and wouldn’t want to know about it now. Microcontrollers simplified that massively.

Thanks for the interesting read. Real nifty little timing/switching circuit!
it’s kinda dogshit but for this application it (cmos version) would be good enough. or better than that, there are dedicated pwm signal generators. i meant this thing in terms of complexity needed
It was a good insight into how the lightbulb dimming tech of the 80s/90s worked. Also why the dimmer switches back then were so dangerous with the capacitor likely just a few mm’s away from the light switch which might not have been properly wired because UK homes back then didn’t run a neutral back from the switch, but daisy-chained the switch and the bulb together and then ran the neutral back from the bulb
Some of the larger disposables do have a charging port. I guess it allows them ship a smaller battery which is good
then you have to interface with charger anyway so ig this makes some more sophisticated chip make sense
ok fine i’d put there a current limiter which you can make with 2 transistors and a diode. no need for an entire microcontroller. it’s often included with batteries these days anyway
- terranoid@lemmy.cafeEnglish17 hours
I believe lithium ion batteries need custom chips just to charge and discharge smartly
Shit, even connecting to modern USB c to negotiate voltage you need a controller
i think you can get away with resistors when you can work with 5V, up to 1.5A. lithium batteries need current limiter in series with voltage limiter, and this alone can be made in a very simple way, unless you want to know when battery is charged, or if you want extra efficiency that smps gives you, but this only makes sense for larger batteries (phone-sized and up) or when you want to handle everything to charger and connect battery to charger directly. then i think you need controller

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.

(The issue with 10-year-old phones on Google is that Google isn’t designed for low-end hardware anymore. It’s overloaded with scripts, styles, and other things that aren’t necessary for doing its job. Present a ten-year-old phone with a page with no client-side script and restrained styling, and I’d bet it would do fine.)
