Wow I lost track of this thread a while ago...
the back link from here... goes back foward to the editor and not the video...

I have videos in the background(private, that I mean to append), I got 57 hours from 2 double AA batteries.
But now that I've used some store bought LED flashlights... near 3 days continuous ontime for 20 LEDs is is actually pretty good.

The real circuit doesn't look like the simulations, the spike disappates faster (it's not just resistive decay)
