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.

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

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 was assuming it was disposable (as so many are) and therefore no charging circuit.

99% spinning a generator and 1% direct solar panels

yep, that’s right - it goes in the square hole we’re boiling water!

it's not all steam

It's just turning water into steam again, isn't it

yeah it's more efficient this way but all you need is ne555 + mosfet tho? still no need for it to be turing complete

then you have to interface with charger anyway so ig this makes some more sophisticated chip make sense

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

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.

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.

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.

I'm sure that'd go over well.

I hope someone accomplishes it, even if it's single digit framerate.

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.
