Mode Zero

Amazing, innovation rulez ok!

I havent seen one of these 10-second chips yet, maybe I've not looked closely enough or maybe its a certain type of vape?

I thought so when I first saw his video, but I checked the last few (ordinary, non rechargable) vapes I found: Lost Mary, etc. and they all had them!
Most seem to be stuck to the cap you pull off, at the opposite end of the vape to the mouthpiece. Look for a tiny watch-battery type of thing - it's the combined switch chip (inside on a tiny PCB) with, I think, a 'suction sensor'. Anyway, you don't need to worry about the suction thing - watch his videos for how to connect a 'start-timer-switch' - and he links to some other YouTuber who's done a more in-depth investigation with circuit diagrams and such.
