Its just that the 'componentless' version in the URL looked too fascinating.
I hear you. Yet another reason to grab a couple of 12LF1822. This one can run on the internal 31kHz osc at around 4-22uA @3V.

Looks like a fun project. I liked the other one he linked to for tripping the shutter with the microphone, but was a little sketchy on how they tripped it with thunder from lightning. The sound arrives a "long" time after the flash...

That would be a neat project if you could trip it with the lightning flash VS sound.

Let me know how this works out. I'm curious.
