“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.
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.
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.
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.
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.
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 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.
Disclaimer: I don’t smoke anything, so I don’t know any details.
Wouldn’t a button connected to a heating coil be a fire hazard? Is there no automatic shut-off based on temperature? If you add enough safety features, it might end up costing about the same as an embedded SoC.
All it would need is a thermal fuse/cutoff, like those in portable heating appliances (air fryers, grills etc.). I wonder what’s needed to include a 10 second on & 30 seconds disabled timer, maybe it’s cheaper
I wonder what’s needed to include a 10 second on & 30 seconds disabled timer, maybe it’s cheaper
555 timer and a transistor or two, I think?
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.
Economies of scale have been doing really funky things to chip prices, then. Yet another demonstration that the universe Does Not Make Sense.
They also do some BMS stuff, and some support limited graphics and UI. Depedns on the moddle
An RC circuit charging up to some threshold voltage. You can even make it adjustable with a variable resistor.
You’re 100% correct. I have mechanical vapes—no safety cutoff, just an 18650 in a conductive tube with wire coils attached to posts. They’re amazing, and they’re extremely dangerous. Turning one into a protected vape with basic features like wattage adjustment? Way cheaper and easier to go SoC!
i disagree with the single transistor. overcharge prevention requires something more (i am not a batteriologist don’t ask me what. i’d do it with a tesla coil because that’d look cooler)
I was assuming it was disposable (as so many are) and therefore no charging circuit.
Huh. The disposables I am occasionally “forced” to get (put it in a 510 thread gramma) have charging ports. I usually have to charge once or twice to get through the full gram.
That being said, the good local dispo just rebranded and gave me a bunch of 510 batteries with the old name on them. These batteries are fantastic and look about the same size as the server in the article
There is a little more to it, pressing the button 5 times turns it on and off. Three times often lets one cycle through power settings. But yeah, anything more than a very minimal programming is frankly suspicious.
It could be a lot is used to get the charge right idk.
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.
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.
Yeah, as per the analysis I did in another post, even a 555 and a couple of transistors to just blink an LED is more expensive than putting a microcontroller like this one there.
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.
Its so you can have a spinny animation when you hit the button.
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.
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.
that’s more powerful than my first computer
can it play Grover Teaches Typing?
Yeah, ZX81, 1k RAM lol
You don’t need a CPU at all for this trash
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.Forgot the phone one too. Or was it a phone “case” ?
Reusing them, even in small experimental projects, underscores a broader sustainability opportunity.
Bigger opportunity would be banning this shit.
outright bans just allow black markets to flourish. harm reduction and public safety campaigns would go much further
We wouldn’t be banning vaping, we’d be banning disposable vapes.
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.
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.
I can’t argue with that. I started to preemptively keep myself OFF of cigs (entire family smokes and I knew I would eventually pick up the habit). For a while now, most of the talk around it I’ve heard is just whether or not it’s cool or cringe rather than how it can be used to quit smoking.
Maybe the disposables wouldn’t be so egregious if you could keep the battery like you used to be able to and just replace the disposable tanks. I think that’s what bothers me the most. We had an okay system before that wasn’t really complicated and wasn’t NEARLY as wasteful.
you’ve not met humans before ?
Vapes should never have existed? Smoking rates and nicotine addiction were finally going down… Then the good old invention of the vape brings it rocketing back again.
This, cartridges make me feel dirty, let alone wasting a entire li-ion cell too.
There are some shops that will actually collect the vapes and send them back to the manufacturer for recycling. But it’s less common than it used to be, which frustrates me to no end, it should be the reverse if anything.
It makes you feel dirty, but the question is do you still do it anyway - and if the answer is yes, that’s the problem. because that’s what drives the whole industry.
Individuals having desires is not “the problem”. That would be corporations having free reign to behave however the fuck they want, so long as they can pay the fed.
There’s more than one problem. Even if politicians weren’t bribey and Citizens United didn’t give corps a license to bribe them, we would still have pollution and other problems because individuals choose convenience over doing the right thing - which is “the” problem I meant.
we should ban all forms of smoking
I’m sure that’d go over well.
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.
they made it harder to get pods and liquid for normal vapes compared to these, and because most ppl by these they primarily stock them
In my mind, nothing with a circuit board is disposable. Pains me to see it.
But can it run DOOM?
Probably
You can run Doom on a literal potato
But not on a Neo Geo!
https://www.youtube.com/watch?v=4f1-7c6WX10
TL;DW - the Neo Geo has a uniquely bad architecture for FPS games making them nearly impossible to get working on the console.
I have seen people run Doom on a pregnancy test, and you are telling me that the Neo Geo can’t run it!?
That video is a hoax. It’s a small screen inserted into a pregnancy test, cables run out the side which is never brought into frame.
It seems since I have made this post that a huge amount of progress has been made in getting FPS games running on the neogeo.
The positive pregnancy test still runs Doom if you are a teenager or a dude with a mistress
That’s being changed, however, as a bunch of determined devs are using raycasting to go around the console’s limitations, being heavily optimized to run SNK’s arcade titles.
I hope someone accomplishes it, even if it’s single digit framerate.
He updated the video a few hours ago saying that some genius accomplished that
Disclaimer: I didn’t actually watch the video, only saw the thumbnail on my feed
I’m curious who your sole downvoter was. Was it a potato producer that dislikes gaming ? Perhaps a lemon farmer who feels their fruit could run doom on 4k. Was it someone who purchased a $5000 dollar rig only to find out they could have bought a singular potato? I guess we’ll never know
Skyrim port for it when?
Right after porting Doom.
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.
Yeah I’ve still got some of mine somewhere. I think the main reason the disposables took the market was partly that they are much cheaper, and partly that many people think they taste better. In my country the government has mandated that they be rechargable and have the flavour thingies replaceable, so they are, but they still seem to get thrown away a lot.
At the early days we had just that. I bought vegetable glycerine, nicotine and some flavour we were set.
…commodified cannabis is garbage and distillate is hotdog water, though
Will it run OG Doom?
This is the new, “Will it blend?” question.
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?
They are too lazy to refill a pod, and replace a pod - not even a coil.
They dont want to bother, and that’s too complicated and they would just loose it anyway - better to buy those throwaway ones.
These are the most common excuses.Instead of asking why people are buying disposables, ask why nobody is buying those reusable vapes. These disposable companies must be doing quite a few things better if people are willing to throw away money and tech.
Price.
That is what they do better.
Many many MANY people would sooner buy something for 5 dollars 20 times then something for $100 once whether financial necessity or not feeling guilty for buying the super expensive thing.
Not to mention people being too lazy to want to do even basic maintenance. Also companies that prefer to sell something people need to keep buying over and over might not offer a longer term version.
Not vaping or even disposable, but my manscaped face trimmer, which is supposedly a higher end one, was the first electric trimmer I’ve gotten that didn’t come with a little bottle of lube and the instructions even said “you don’t need to lube this!” Knowing that they hadn’t changed the laws of physics, I lubed it anyways and I’m convinced that’s the only reason it hasn’t permanently seized up by now because even with the lube and a full charge, there have been times where it didn’t want to start going without a good tap after turning it on.
IMO it’s quality for the price more than just price, I’ve bought and used so many brands of refillable pods/tank mods and they always have quality problems that just don’t happen with the disposables. For anyone that’s experienced them, all I have to say is e-juice leakage.
Ads and influencers pushing them.
Ok here’s my billion dollar idea: vapes that already are web servers!
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.
ಠ__ಠ
OK, but can it run Doom?
x86 at 25MHz could barely run it. This is ARM at 24.
Also 3KB of RAM. That has to be too little.
Yeah, I think I had 2-4MB, but it was a long time ago, so I could be mistaken.
It also had an FPU addon, which I don’t think the M0 has.
When I was a kid we had a 386-33MHz with 4MB RAM, it ran Doom at about 1-2FPS. Upgraded to a 486 DX (66MHz I think?) and 8MB RAM and it ran great on that. It’s possible that the 386 would have been fine if we put more RAM in though, I think the biggest issue was swapping.
Set it to low quality and hit Ctrl+Minus until the window is the size of a postage stamp and it’s buttery smooth.
People got it running on a pregnancy test once, so…
To clarify, it wasn’t running on the pregnancy test, it was just outputting to one.
And the screen had been replaced… so it was truly pointless.
Lmao, I didn’t know that part. Yeah, at that point who fucking cares. 😂
Came here looking for this question
Next up, turning these into AI web scraper bots!
/pleasedon’tdothis
But does it run doom?
What can I do with my samsung smartphone whose screen is broken?
Hardware isn’t the limitation, its willingness to fight locked down hardware and the power management of android. You might be able use ADB to control it, install termux and then with that, SSH server and then a server of some sort.
In my experience, most phones don’t seem to boot sans battery, so its just a matter of time until the battery goes poof and your system goes down. Some manage it though - you do get a decent amount of hardware for the power consumption.
How broken is it? Touch still works? Display visible?
Probably only replacing the screen would work at this point. Android is quite flexible but you need some touch input to operate it.
Android can take keyboard and mouse input actually
You’re right, I haven’t thought of that. Maybe connecting it to a monitor through an HDMI enabled USB-C hub could work.
It just got dramatically worse, screen jumps up and down, unusable I won’t even be able to take phone calls. I can’t even restart it.
If it’s an OLED and it’s cracked you have only a couple hours to get your shit off of it before it goes completely blank. LCDs are usually somewhat fine depending on how they’re broken. They don’t get worse
Depending on how security is, you can plug a USB-c hub and connect it to a KBM and run it that way…
I had to read your comment several times before I realized you didn’t type USB-chub.
It took a day to go from partially fucked to unusable, the entire screen is like seizuring. There was no actual crack though, must have hit a rock or something getting lobbed onto the ground.
Interesting stuff
