When there's no time to mess around with baby blinkies, grab your favorite astable setup and swap out those cute little Nancy transistors for a matching set of Darlington pairs like you see here!
Scoped this one on the net the other day- I'd wondered previously about implementing darlingtons into our beloved astable, but it went on the back burner of my mind cuz honestly, I really wasn't tryin to mess with anymore damn blinkies lol. But then I spotted this one (and a few others) and I had to give it a shot.
The schematic (which can be found at Techlib.com) called for 2N4401's, and pretty straightforward component values- but I had to adjust those to get the circuit tuned up nice for show and tell. My thoughts?: it's cool- and, remarkably stable actually.. <=^)
