Ionescu decided to use the chip’s ability to handle the old Serial Line Internet Protocol (SLIP).
With it, he turned the unit into a very basic 56K modem equivalent. He then added uIP 0.9 code to enable TCP/IP communication and web serving.
Hah, cool. I was wondering if it has WiFi, serial stuff makes more sense.
The ecig waste is tragic though.
The question is why a disposable vape needs a high performance 32-bit 24 MHz ARM MCU. What exactly does it do that can’t be accomplished by an 8-bit microcontroller.
Particle effects
the fancier models come with screens and lite OSs now where you can do useless stuff like set lights and track puffs and what have you
Yeah disposable vape pens are a massive e-waste. Usually the batteries and electronics are still totally functional. There was a YouTuber making a large rechargeable battery from discharded vape pens although you really need to have the same make and model to pull that off as you need the cells to be mostly identical at to avoid the possibility of it exploding or catching fire. So yeah if you can collect hundreds of the same disposable vape pen you can build yourself a pretty serious battery.

But does it run Doom?

The MCU only has 3KB of SRAM so probably not. I think you need at least something like a Pi Pico or an ESP32 for that.

Huh. Hadn’t looked up the original specs in… Ever? Idk. Operating system: MS-DOS 5.0 or higher Processor: Intel 486 DX2/66 MHz or equivalent RAM memory: 4 MB Hard drive: 10 MB free space Sound card: compatible with Sound Blaster
Looks like you are correct without an upgrade.
