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.
