stop click-bait extension: it uses a miniature generator to create a spark.

...which is exactly what I expected, but there were some little extras that I did not-
-The NO switch at the bottom so that the circuit is only closed at the end of the stroke, when the generator is going full speed
-The ratchet so that power isn't generated on the upstroke (well, I guess that's covered by the switch as well)

Bigclive opened up a more recent one the other day, which may be what prompted Cody to open his: https://www.youtube.com/watch?v=FbAxn5dgoic
Both really quite cool.

In college, one of the senior design projects had a guy who re-engineered gas grill igniters, to improve on the push-button type. He wound up doing a pull-cord style igniter, like you'd use to start a mower or weed eater.
I had thought that was the best slightly-ridiculous hypothetical grill starter. Until today.

Big Clive has a really straightforward explanation of how they work.

Whatever happened to the crisis of blasting cap danger? In the 70's, Saturday morning PSAs convinced me that I was very likely to be killed by stray blasting caps.

A TV PSA I remember from my childhood featured Willy Mayes saying - Play with these (holds up bat and glove), not with these (picture of blasting caps.) Being young and impressionable I too expected to find these things lurking about everywhere. But no, not a one ever appeared. And since these PSAs seem to have disapppeared, is the danger really gone? And why?

I also thought the self-amplifying output-to-field trick was clever. I wouldn't have thought to do that right away if I were trying to re-create one from my mental image.

I'd never really considered how the cartoon-style TNT plunger might have worked internally, so I was really interested to see what goes on in there. I don't think I would have guessed using magnets to generate electric charge, but given the amount of thought I'd put into it, I'm not sure I would have had an answer other than "magic". Anyway, this was interesting stuff, and I generally enjoy Cody's Lab (although I wish he'd do more chemistry and less gardening).
